DETAILED DESCRIPTION OF EXEMPLARY MODALITIES

The exemplary embodiments discussed in this document are directed to systems, methods, and devices for contact mechanisms for electrical receptacle assemblies. While the exemplary embodiments in this document are directed to electrical receptacle assemblies for use in a potentially hazardous location, other exemplary embodiments may be used in other types of applications. Exemplary embodiments can be used with electrical receptacles found in one or more of a variety of environments, indoors or outdoors, where the electrical receptacle (also referred to herein simply as a receptacle) can be exposed. Examples of such environments may include, but are not limited to, humidity, dirt, exhaust fumes, vibrations, possible explosions, and noise.

In one or more ways, the electrical receptacle can be part of an eonfecnedeii? ¹ explosion-proof and / or located in some other potentially hazardous location. An explosion-proof container (also known as a flame-proof container or a hazardous location container) is a container that is configured to contain an explosion originating within the container. Furthermore, the explosion-proof container is configured to allow gases from within the container to escape through the joints of the container and cool them as the gases exit the explosion-proof container. Junctions are also known as flame paths and exist where two surfaces meet and provide an uninterrupted path, from within the explosion-proof container to the outside of the explosion-proof container, along which one can travel. or more gases. A joint can be a coupling of any two or more surfaces. Each surface can be any type of surface, including but not limited to a flat surface, a threaded surface, a grooved surface, and a serrated surface.

In one or more exemplary embodiments, an explosion-proof container is subject to meeting

<img file="MX348371B_D0006.tif" />

certain standards and / or requirements. For example, NEMA sets standards that a container must meet to qualify as an explosion proof container. Specifically, NEMA Type 7, Type 8, Type 9, and Type 10 containers establish standards that an explosion-proof container must comply with within a potentially hazardous location. For example, a NEMA Type 7 standard applies to containers built for indoor use in certain hazardous locations. Hazardous locations may be defined by one or more of a number of authorities, including but not limited to the National Electric Code (for example, Class I, Division 1) and Underwriters' Laboratories, Inc. (UL) ( eg UL 1203). For example, a Class I hazardous area under the National Electrical Code is an area in which flammable gases or vapors may be present in the air in amounts sufficient to be explosive.

As a concrete example, the NEMA standards for an explosion-proof container of a certain size (for example, (100) cm³) or range of sizes, may require that in a Group B, Division 1 area, any flame path from an explosion proof container must be at least 25.4 mm long (continuous and unbroken), and the space between surfaces cannot

Standards created and maintained for exceeding 0.04 mm.

NEMA can be found at www.nema.org/stds and are incorporated herein by reference.

Exemplary modalities can also be used with containers that are used in non-hazardous locations that do not require compliance with an explosion-proof container. For example, receptacle assemblies using exemplary contact mechanisms can be part of a NEMA Type 3R enclosure, which can be used indoors or outdoors and which can provide a degree of protection against the penetration of solid foreign objects (e.g. , dirt, dust), the penetration of water (eg rain hail, snow) and the formation of ice in the container.

The exemplary receptacle assemblies (or their components) described herein can be made of one or more of a number of suitable materials to enable the receptacle assemblies to meet certain standards and / or regulations while also maintaining durability in view of the one or more more conditions to which canister assemblies can be exposed. Examples of such materials can include, but are not limited to, aluminum, stainless steel, fiberglass, glass, plastic, and rubber.

Housing (110) may also include a base portion (114) that is configured to mechanically engage a body of a container (eg, junction box, explosion-proof container, motor control center). . Base portion 114 may include one or more mating features 118 (in this case, openings) that are configured to engage corresponding mating features of the body on the container. The mating features 118 of the base portion 114 may include, but are not limited to, openings, slots, clips, clamps, and tabs. The base portion (114) can be mechanically coupled to the body of a container using one or more of a number of coupling methods, including but not limited to clamping devices (eg, bolts), welding, compression fittings and bracketing .

Housing (110) may also include at least one wall (112) that extends from base portion (114) at some angle. The wall (112) may have an inner surface (113) and an outer surface (111). The wall (112) may form a cavity (119), defined by the inner surface (113) of the wall (111), in which one or

<img file="MX348371B_D0008.tif" />

More components (eg, inner body (180), outer body (400)) of electrical receptacle (100) can be provided. The cavity (119) may be formed by multiple adjacent internal surfaces (eg, internal surface (113), internal surface (115)) of wall (112). The cavity (119) can pass through the base portion (114) of the housing (110). Figures IB and ID also show the external body (400) disposed within the cavity (119). Specifically, a portion of the outer body (400) is shown mechanically coupled to the inner surface (113) of the wall (112). The inner surface (113) of the wall (112) and / or the outer surface (429) of the outer body (400) may have one or more mating characteristics that allow the outer body (400) to mechanically engage the inner surface ( 113) from the wall (112). Furthermore, said engagement features may allow movement (eg, rotary) of the outer body (400) within the cavity (119) formed by the wall (112) of the housing (110).

Such a portion of a housing (110), as well as the clamping devices (185), may be made of an electrically conductive material.

Figures 2A-2E show different views of the internal body (180) of the electrical receptacle (100) of Figures 1A-1D according to certain exemplary embodiments. Specifically, Figure 2A shows a bottom view of the inner body (180). Figure 2B shows a lower side perspective view of the inner body (180). Figure 2C shows a top view of the inner body (180). Figure 2D shows a lower side perspective view of the inner body (180). Figure 2E shows a cross-sectional side view of the inner body (180). In one or more exemplary embodiments, one or more of the components shown in Figures 2A2E may be omitted, repeated, or substituted. Accordingly, exemplary embodiments of an inner body (or portions thereof) should not be considered limited to the specific arrangements of the components shown in Figures 2A-2E.

Referring to the figures'^&gt;'^sé ^ Lr&gt;

Inner body (180) may have multiple sedCluiiea ·: —- goc For example, as shown in Figures 2A-2E, the inner body (180) may have an upper section (220), a central section (250), and a lower section (290). The lower section (290), shown in detail in Figures 2A and 2B, may include the lower surface (182), the raised section (181), and one or more channels (183). With the fasteners (185) and posts (184) removed, an end portion (301) of a number of resilient elements (300) is shown disposed on the bottom surface (181). These resilient elements (300) are described in more detail below with respect to Figures 3A-3C. In certain exemplary embodiments, the resilient elements (300) are overmolded into the inner body (180). Alternatively, the resilient elements (300) may be pressed or otherwise mounted to the inner body (180). For example, the end (301) of the resilient member (300) can be mechanically coupled to the bottom surface (182) of the inner body (180) using a clamping device (185). The resilient elements (300) can be considered a separate component, or part, of the internal body (180).

The end portion (301) of the resilient elements (300) may be substantially on the bottom surface (182). ΆΗΡΓηΑΐ-ινΑπίΡη ^) the end p ^ rr-ίήη (301) of the resilient elements (300) can be raised from, or sunk within, the bottom surface (182). The raised section (181) may have a side wall (275) that has a height. The height of the wall (275) (and therefore the height of the raised portion (181) relative to the bottom surface (182)) may be greater than the combined height of the end portion (301) of a resilient element (300) (or, more precisely, the portion of the end portion (301) that protrudes over the lower surface (182)), an electrical conductor, a terminal (184) and a clamping device (185) . In such a case, all these components are arranged within a channel (183) and are protected within the walls (275) of the raised section (181).

The central section 250 of the internal body 180 may have one or more than a number of recesses (hidden from view) each having a shape and / or size that is substantially similar to the shape and / or size of an end portion (301) of the resilient element (300). Additionally, other portions of the resilient member (300) may be disposed in one or more openings (hidden from view) through the central section. In such a case, the end (301) of the resilient element (300) which is

<img file="MX348371B_D0012.tif" />

opposite the end portion (301) may be exposed in the upper section (220).

The center section (250) may also have an outer surface (222) that has one or more of a number of engagement features disposed thereon. Examples of such engagement features disposed on the outer surface 222 may include (as shown), but are not limited to, engagement threads, grooves, tabs, retainers, and clips. In certain exemplary embodiments, the engagement features provided on the outer surface (222) of the central section (250) of the inner body (180) may complement the engagement features provided on the inner surface (113) of the wall (112) of the housing (110), within which the internal body (180) is arranged.

Once positioned within the cavity (119) of the housing (110), the inner body (180) can remain stationary. In such a case, the mating features arranged on the outer surface (222) of the inner body (180), the mating features arranged on the inner surface (113) of the wall (112) of the housing (110), and / or Some other feature (e.g. a weld, a clamping device) can be used to ensure that the inner body (180)

maintain a stationary position within the cavity (119).

In certain exemplary embodiments, the center section (250) also includes one or more fastener receivers 285 that traverse at least part of the center section (250). Fastener receivers 285 are configured to receive and engage fastener devices (185). In such a case, the clamping device (185), as well as the components (for example, a resilient element (300), a terminal (184)) of the electrical receptacle (100) arranged between the clamping device (185) and the lower surface (182) of lower section (290) of inner body (180) can be mechanically coupled to inner body (180).

The upper section (220) of the inner body (180) may have at least one wall (224) and a bottom wall (254) that forms a cavity (299). The wall (224) may have an inner surface (253), an outer surface (289), and a top surface (252). In certain exemplary embodiments, the at least one wall (224) has one or more features that are disposed along its inner surface (253). For example, as shown in Figures 2A-2E, the inner surface (253) may include one or more (in this case, three) of a number of recesses (256). Said breaks can be arranged in

The width of the recess (256) may be greater than a width of the end (302) of the resilient member. Thus, the end (302) of the resilient member (300) can be pushed out toward the recess (256) with a displacement less than the distance (257) without touching the wall of the recess (256). The number of recesses (256) can be at least as large as the number of resilient elements (300).

Referring to Figures 1A-3C, the resilient element 300 (sometimes known by other terms, such as a laminated spring) is made of a ²³ iMPie&gt;

Mexican institute oe la monedad V * V- ** ST industrial electrically conductive material. As indicated above, the resilient element (300) has a first end (302) and a second end (301). End (301) and end (302) may be substantially perpendicular to each other. In other words, the angle (377) between the end (301) and the end (302) can be substantially 90 ° under normal conditions (for example, when no lateral force is applied to the front surface (332) and / or the front surface (350) of the end (302)).

The end (301) and the end (302) of the resilient member (300) may be joined by a curved section (315). The curved section (315), t he end (301) and the end (302) may be made in one piece (such as from a mold). Alternatively, curved section (315), end (301), and / or end (302) may be multiple pieces that are mechanically coupled to each other by one or more of a number of coupling methods, including but not limited to welding. , compression fittings and restraint devices.

In certain exemplary embodiments, the curved section (315) and / or the elongated length of the end (302) provides an amount of flexibility that allows the end (302) to be moved rearward, causing the angle (377) between the end (301) and the end (302) is ²⁴ WICKED

In certain exemplary embodiments, the end (301) has an opening (385) through it. Such opening (385) may be large enough to receive a clamping device (185). The end (301) can have any number of shapes. For example, as shown in this example, end 301 has a substantially circular shape when viewed in cross section from above. Other shapes can include, but are not limited to, a square, a hexagon, and an octagon. The shape and / or size of the end (301) may be substantially the same as the shape and / or size of the recess in the lower surface (182) of the lower section (290) of the inner body (180).

In addition, the top surface (301) and the bottom surface (311) of the end (301) can have a width (measured from the outer perimeter of the opening (385) to the side (312)). The depth and width of the end (301) can be

Sufficient to ensure solid mechanical and electrical contact with an electrical conductor, a terminal (184) and / or a ground connection (186). The depth and width of the end (301) may also be sufficient to maintain the resilience of the resilient element (300) from lateral forces applied to the end (302) while the end (301) maintains mechanical and electrical contact with an electrical conductor, a terminal (184) and / or a ground connection (186).

In certain exemplary embodiments, some other clamping and / or mating features, in addition to or in place of the aperture (385), may be used to mechanically and electrically couple the end (301) to an electrical conductor or ground (186 ). For example, a slot, tab, or clamp may be used in place of an opening (385) and a clamping device (185) to mechanically and electrically couple the end (301) to an electrical conductor or ground ( 186).

The end (302) of the resilient element (300) can be an elongated segment having one or more of a number of characteristics. The elongated segment that forms the end (302) can have one or more of a number of shapes. For example, in this case, the end (302) is formed by a larger rectangular section adjacent to

The lower (and larger) rectangular section may have a front surface (332), a pair of side surfaces (338), and a rear surface (333). The corners where these surfaces meet can be substantially square, similar to the corners of the end (301).

The upper end section (302) has a front surface (350), two side surfaces (336), and a rear surface (339). While the corners formed by the rear surface (339) and the two side surfaces (336) may be substantially similar to the corners formed at the lower end section (302), the corners (337) formed by the front surface (350 ) and the two side surfaces (336) can be beveled. These beveled corners (337) can be used to assist end (302) in interacting with various portions of outer body (400), as described below with respect to Figures 4A-4D. The angles between the top surface 330 and the front surface (350), the side surfaces (336) and the rear surface (339) may be beveled or substantially the same as the end corners (301).

Furthermore, the front surface (332) and the rear surface (333) of the lower end section (302) may have a width that is greater than the width of the front surface (350) and the rear surface (339) of the top end section (302). Similarly, the curved section (315) may have a width (substantially equal to the width of the front surface (332)) and a depth (substantially equal to, or a range between, the depth of the side (312) and / or the lateral surface depth (338)).

The depths and widths of the end (302), as well as the curved section (315), may be sufficient to guarantee a solid mechanical and electrical contact between the front surface (350) and an extension (475) of the external body (400), as described below with respect to Figures 4A-4D. The depths and widths of the end (315) and the curved section (315) may also be sufficient to maintain the resilience of the resilient member (300) from lateral forces applied to the end (302) while the end (301) maintains mechanical contact and electrical conductor with an electrical conductor, a terminal (184) and / or a ground connection (186). Although many of the surfaces (e.g. front surface 350, chamfered corners 337, front surface 332) of resilient member 300 are shown to be substantially flat and smooth, such surfaces may, in addition, or alternatively, have one or more of a number of other characteristics, including, but not limited to, curvature (eg, concave, convex), serrated edges, and texture.

Figures 4A-4D show different views of the outer body (400) of the electrical receptacle (100) of Figures 1A-1D according to certain exemplary embodiments. Figure 4A shows a bottom view of the outer body (400). Figure 4B shows a side view of the outer body (400). Figure 4C shows a transverse side perspective view of the outer body (400). Figure 4D shows a bottom perspective view of the outer body (400). In one or more exemplary embodiments, one or more of the components shown in Figures 4A-4D may be omitted, repeated, and / or substituted. Consequently, exemplary embodiments of an external body (or portions thereof) should not be considered limited to the specific arrangements of the components to be

IMPT ^^ shown in Figures 4A-4D.

Referring to Figures 1A-4D, the outer body (400) can have one or more of a number of different portions. For example, as shown in Figure 4B, the outer body (400) may have an upper portion (477), a central portion (478), and a lower portion (479). In this example, all of the portions are concentric, with the upper portion (477) and the lower portion (479) having substantially the same outer perimeter, which is slightly smaller than the outer perimeter of the central portion (478). The space formed between the lower portion (479) and the central portion (478) forms a shelf (471). Likewise, the gap formed between the outer surface (403) of the upper portion (477) and the outer surface (429) of the middle portion (478) forms a shelf (405).

One or more plug assemblies (424) can be positioned within the outer body (400). Each plug assembly (224) can be part of a terminal receiver. In such a case, the terminal receiver may also include an opening (not shown) provided in the upper surface of the outer body (400). Each plug assembly (424) can traverse part or all of the height of the outer body (400). The plug assembly (424) may be made of an electrically conductive material so that the ³⁰ IMPIOS institute me or

The plug assembly (424) can have one or more of a number of configurations. The purpose of each plug assembly (424) is to receive a terminal from an electrical plug and provide substantial mechanical contact with the terminal so that the electrical coupling between the plug assembly (424) and the plug terminal is consistent and not clamped. to bowing, faults, or other adverse conditions that can lead to an interruption in the flow of electricity between the plug terminal and the plug assembly (424).

Each plug assembly (424) can be configured in one of several ways. In this case, the plug assembly 424 is circular with four quadrants that are divided by two cuts that run along the diameter through the center and are perpendicular to each other. When a terminal of an electrical plug is inserted into the

IMPI Terminal Receiver (424), the plug assembly (424) can be expanded while applying sufficient internal force towards the terminal, thus maintaining solid mechanical contact with the terminal, leading to solid and consistent electrical contact between the terminal and plug assembly (424). The electrical plug carries electrical energy, which is transferred through the terminals of the electrical plug to the plug assemblies (424) when the terminals of the electrical plug are mechanically coupled to the plug assemblies (424).

In certain exemplary embodiments, an extension (475) is attached to the lower end of the plug assembly (424). The extension (475) can be made of an electrically conductive material, which can be of the same or different material as the plug assembly (424). The extension (475) can be used to contact another electrically conductive element (in this case the front surface (350) of the resilient element (300)) positioned adjacent the lower portion (479) of the outer body (400) when the body is rotated external (220) to a determined position. In such a case, the distal end of the extension (475) protrudes through, or is accessible in, an opening provided in the lower portion (479) of the outer body (400).

The extension (475) may be integrally formed (such as from a mold) with the pin assembly (424). Alternatively, the extension (475) may be a separate piece that is mechanically coupled to the plug assembly (424) by one or more of a number of coupling methods, including but not limited to welding, fasteners, and compression fittings. In addition, the plug assemblies (424) can traverse the upper portion (477), the central portion (478), and at least a portion of the lower portion (479). The extensions (475) may be arranged at the bottom (479).

The plug assemblies (424) and extensions (475) may be contained in bushings (415). Each bushing (415) can be made of a non-electrically conductive material. Each socket may abut directly against, or be adjacent to (have a gap between), a plug assembly (424) and / or an extension (475).

In certain exemplary embodiments, the central portion (778) has an outer surface (429) in which one or more of a number of engagement features (in this case, engagement threads) are disposed. Therefore, by using the mating features on the outer surface (429), the central portion (778) (and thus the outer body (400)) can be mechanically coupled to the inner surface (113). from the wall (112). The mating features provided on the outer surface (429) of the central portion (778) and on the inner surface (113) of the wall (112) can allow the outer body (400) to move (eg, rotate) within the cavity (119) of the housing (110). Specifically, the outer body (400) can be moved between an off position (electricity does not flow through the electrically conductive components of the electrical receptacle (100)) and an on position (electricity flows through the components electrically conductive electrical receptacle (100).

In certain exemplary embodiments, the lower portion (479) is where the extensions (475) are exposed, allowing the extensions (475) to do

Specifically, the extensions (475) may protrude through one or more openings (hidden from view) in the side wall (469) of the lower portion (479). In such a case, the ends of the extensions are exposed.

In addition to the extensions (475), the lower portion (479) can include one or more than a number of features. For example, the lower portion (479) may include at least one retainer (467) located on the side wall (476) adjacent to an extension (475) on one side of the retainer (467) and the start slot (461). to the other side of the retainer (467). Each retainer (467) is positioned relative to the adjacent extension (475) such that the front surface (350) of a resilient member (300) contacts the retainer (467) when the outer body (400) is between the on position and the off position. The front surface (350) of a resilient element (300) contacts the start slot (461) when the outer body (400) is in the off position, and the front surface (350) of a resilient element (300 ) makes contact with extension (475) m Γ1 f

The shape and size of the retainers (467) provide a level of resistance when the outer body (400) is in the off position (that is, when the front surface (350) of a resilient element (300) contacts the start slot (461)), which prevents the outer body (400) from rotating relative to the inner body (180). Similarly, the shape and size of the retainers (467) (in this case, the outer edge of the retainer, positioned adjacent the extension (475)) provides a level of resistance when the outer body (400) is in the off position. on (that is, when the front surface (350) of a resilient member (300) contacts the extension (475)), which prevents the outer body (400) from rotating relative to the inner body (180).

retainers (467) can be large enough to prevent inadvertent repositioning of the outer body (400). For example, retainers (467) can provide sufficient resistance against resilient members (300) to prevent outer body (400) from moving out of the on position when vibrations are present. However, a sufficiently large rotational force applied to the outer body (400) can overcome the resistance provided by the retainers (467) against the resilient elements (300). For example, when an electrical plug is inserted into the plug assembly (424) and applies a rotational force in the correct direction, the outer body (400) may change position.

Another feature of the lower portion (479) of the outer body (400) is at least one protrusion (472) that extends outward of the side wall (476). The bulge (472) may be disposed on the side wall (476) adjacent to a start slot (461), a retainer (467) and / or an extension (475). The bulge (472) may have a width that is less than the width of the recess (258) in the inner body (180). In this case, the protuberance (472) can be placed inside the recess (258) ”IMPI instituto mexicana 11

FROM THE INDUSTRIAL Cn-v ™ INNER BODY (180). Because the inner body (180) remains stationary when the outer body (400) moves (for example, rotates), the recess (258) of the inner body (180) can limit the movement of the bulge (472), which in turn limits the movement of the external body (400).

The positioning and orientation of the seals (467), The bulge (472) and the side walls (469) through which the extensions (475) are disposed may be arranged to correspond with the positioning and orientation of the recess (258) and the ends (302) of the resilient elements ( 300) so that the ends (302) of the resilient elements (300) make contact with the retainers (467) when the protrusion (472) is positioned at one end of the recess (258) (corresponding to the outer body (400) in the position of off), and thus the ends (302) of the resilient elements (300) make contact with the extensions (475) when the protrusion (472) is positioned at the other end of the recess (258) (which corresponds to the outer body (400) being in the on position).

Unless otherwise indicated, the various components of the outer body (400) may be made of one or more of a number of non-electrically conductive materials.

The figures

5A-5D show different views of a subassembly (500) of the electrical receptacle of Figures 1A-1D according to certain exemplary embodiments. Figure 5A shows a cross-sectional side view of the subassembly (500). Figure 5B shows a side view of the subassembly (500). Figures 5C and 5D each show a transverse side perspective view of the subassembly (500). In one or more exemplary embodiments, one or more of the components shown in Figures 5A-5D may be omitted, repeated, and / or substituted. Accordingly, exemplary embodiments of a subassembly of an electrical receptacle (or portions thereof) should not be considered limited to the specific arrangements of components shown in Figures 5A-5D.

In this case, the subassembly (500) includes the inner body (180), the outer body (400), and a faceplate (510). Referring to Figures 1A-5D, the interaction of the components of the upper section (220) of the inner body (180) and the lower portion (479) of the outer body (400) can be seen more clearly. In Figures 5A-5D, the outer body (400) is in the off position, which means that the ends (302) of the resilient elements (300) come into contact with the retainers (467) of the lower portion ( 479) the outer body (400) instead of the extensions (475).

When the inner body (180) and the outer body (400) are positioned within the cavity (119) of the housing (110), the cavity (299) formed by the at least one wall (224) and the bottom wall (254 ) of the upper portion (220) of the inner body (180) is contained (or substantially contained) by the lower portion (479) of the outer body (400). In this example, because the outer body (400) rotates along with the mating threads between the off and on positions, there is some vertical displacement in the position of the outer body (400) relative to the inner body (180 ), which remains stationary as the outer body (400) moves between the off and on positions.

Therefore, in this example, if the body

<img file="MX348371B_D0018.tif" />

outer (400) is in the off position, there is a gap (525) between the shelf (471) of the outer body (400) and the upper surface (252) of the wall (224) of the inner body (180). As shown in Figures 7A and 7B below, when the outer body (400) in this example rotates from the off position to the on position, the gap between the shelf (471) of the outer body (400) and the upper surface (252) of wall (224) of inner body (180) may taper. When the exemplary electrical receptacle (100) is coupled to the body of a container that is used for certain applications, such as potentially hazardous environments, the upper portion (220) of the inner body (180) and the lower portion (479) of the outer body (400) can form their own explosion proof container, forming cavity (299).

In certain exemplary embodiments, the outer body (400) is mechanically coupled to the face plate (150). As shown in Figure ID, the inner surface (115) is located on the inner surface (113) of the housing (110). In certain exemplary embodiments, the inner surface (115) is smooth and has no features disposed thereon. The inner surface (115) may be sized and / or shaped to receive

The outer perimeter of the inner surface (115) may be substantially the same, or different, from the outer perimeter of the inner surface (113).

In certain exemplary embodiments, the faceplate (150) acts as an interface between the terminals of an electrical plug and the plug assemblies (424) of the outer body (400). The faceplate (150) may have one or more of a number of features and / or configurations. An example of a faceplate (150) can be found in the US patent application entitled Locking Features for Electrical Receptacle Mounts, as referenced and incorporated by reference above in connection with the first paragraph of this description.

Referring to Figures 1A-7B, when the outer body (400) is in the off position (900), the end (302) of the resilient elements (300) is in contact with the retainers (467) of the portion bottom (479) of the outer body (400). In other words, the end (302) of the resilient elements (300) is not in contact with the extensions (475) of the outer body (400). As a result, with the lack of mechanical coupling between the resilient elements (300) and the extensions (475), electrical energy does not flow through the electrical receptacle (100).

Furthermore, as indicated above, there is the gap (525) between the shelf (471) of the outer body (400) and the upper surface (252) of the wall (224) of the inner body (180). If the electrical receptacle (100) is used in a hazardous environment, then the container formed by the upper portion (220) of the inner body (180) and the lower portion (479) of the outer body (400) can be considered a test container. of explosions. In such a case, the gap 525 (in this case, a flame path) may be too large. However, because there is no electrical path between the

As the outer body (400) is rotated from the off position (600) to the on position (700), the retainers (467) can apply an external force to the ends (302) of the resilient elements (300 ). As a result, the distance (257) between the end (302) of the resilient member (300) and the adjacent recess (256) may decrease until the retainers (467) stop contacting the front surface (350) of the resilient members. (300). When this occurs, the outer body (400) is in the on position (700), and the front surface (350) of the end end (302) of the resilient elements (300) makes contact with the extensions (475). In other words, because the resilient members (300) are resilient, the distance (257) between the end (302) of the resilient member (300) and the adjacent recess (256) is restored when the retainers (467) stop applying an external force to the front surfaces (350) of the resilient elements (300).

Furthermore, when the outer body (400) is moved to the on position (700), a smaller gap (725) results between the shelf (471) of the outer body (400).

and the upper surface (252) of the wall (224) of the inner body (180). The gap (725) is smaller than the gap (525) that exists when the outer body (400) is in the off position (600). When the outer body (400) is in the on position, the resilient elements (300) make contact with the extensions (475). As a result, electric current flows through resilient elements (300) and extensions (475) within cavity (299). In such a case, when the electrical receptacle (100) is used in a hazardous environment, the gap (725) may be a flame path. In certain exemplary embodiments, the outer body (400) and the inner body (180) are configured and oriented such that the gap (725) formed when the outer body (400) is in the on position (700) complies with one or more standards and / or regulations for the flame path of an explosion proof container.

Referring to Figures 1A-8, the electrical plug (800) (also called simply a plug (800)) may include a plug body (822). The plug body (822) may be shaped and sized to allow at least a portion of the distal end to be disposed within the cavity (119) of the housing (110) to allow engagement between the plug (120) or the electrical receptacle (100). In this case, the transverse shape of the plug body (822) is circular, which coincides with the transverse shape of the cavity (119) of the housing (100).

A number (in this case three) of terminals (858) extending outwardly from the end surface (851), are disposed on the end surface (851) at the distal end of the plug body (822). The terminals are made from one or more of a number of electrically conductive materials, including, but not limited to, copper and aluminum. The shape, size, orientation, and positioning of the terminals (858) are configured to be substantially complementary to the shape, size, orientation, and positioning of the terminal receivers traversing the faceplate (510) as well as the plug mounts ( 424) from the body

If the shape, size, orientation, and positioning of the terminals (858) are not substantially complementary to the shape, size, orientation, and positioning of the terminal receivers traversing the faceplate (510) and pin mounts (424) of the external body (400), then plug (800) cannot mechanically and electrically couple to electrical receptacle (100).

Specifically, Figure 9A shows a side view of the subassembly (900) with the outer body (400) and the front plate (510) in transparency. Figures 9B and 9C each show different cross-sectional side views of subassembly (900) with outer body (400) and front plate (510) in transparency. In one or more exemplary embodiments, one or more of the components shown in Figures 9A-9C may be omitted, repeated, and / or substituted. Consequently, exemplary embodiments of an electrical plug and electrical receptacle (or portions thereof) must not
