Switch wiring improvement device

The present invention relates to a switch wiring improvement device; in particular, a switch wiring device is provided with a limiter, a contact piece, a combined metal dome to facilitate direct pivoting of the wire; and, in the case of a higher rigidity, the limiter is A new type of auxiliary that fixes and regulates the path of metal shrapnel movement.

The switch wiring device is a power switching element having a connection circuit or a line, and is installed in an operation panel or a distribution box of an electronic or electrical device to connect the wiring circuit. The switch wiring device is applied to a conductive component, a screw-locked electronic device, a wiring circuit or a wire of a motor device, which is covered in an insulating case (usually made of a plastic material), and controls the conductive component and the wiring circuit with the operation of the switch button or It is a well-known technique to establish the power supply of the open and close circuits by energizing or de-energizing the wires; for example, Taiwan Patent No. 103206602 "Switching Terminal Block Structure" patent provides a typical embodiment.

One problem related to the operation and structural design of such a switch wiring device is that the insulating housing is provided with a connecting wire hole and a locking hole for the operating screw, and a person operating tool is provided to control the screw locking from the wire insertion hole. wire. In practice, the screw must be in the released state so that the wire can be inserted into the plug hole; when the screw is in the released state, the screw will be skewed, so often the person operates the screw to align the lock wire and connect The operation of the electric head (or electric terminal) becomes troublesome and difficult.

In order to improve the above problems, the old method also discloses a structure in which a guide groove and a guide bar and a spring are provided on an insulating case and a power receiving head. However, the structure is not only complicated, but also increases the manufacturing cost; and, it is usually necessary to increase the volume of the casing to avoid interference between the guiding structure and the conductive member. Furthermore, increasing the volume of the housing is also detrimental to the evolution and design trend of miniaturization of the switch terminal device.

In some environments (such as the vibration of the machine equipment), the long-term use process, it is easy to loosen the screw, causing the wire to loosen. In particular, the screwing mechanism of the screw mechanism and the wire or wire must use tools to operate the locking and relaxing work, which is relatively cumbersome; this situation is not what we expected.

The old method also reveals a structure that fits the internal structure of the casing, and uses a metal dome that is shaped like an α-profile to press a wire or a wire to replace the structure of the screw-locking wire. However, as those familiar with the art know, in addition to bending into a special shape, the α-shaped metal dome must also have a mouth on the metal dome so that the other end of it passes through the mouth, at the mouth. A swingable structure is formed thereon to press the wire. Therefore, the α-type metal shrapnel is cumbersome and complicated in structure fabrication; this situation is not what we would expect.

Representatively, these references show the skill in the design of the switch wiring device and related combinations; if the re-design considers the structural combination of the insulating housing and the conductive components, the connector, and the switch, the structure is different. The learner will be able to change its use form, which is different from the old one; in essence, it will also increase its application range. For example, under the condition that the volume of the switch wiring device is not increased, the structure thereof is easy to manufacture and operate, and the operation and the difficulty of the conventional operation screw for aligning the locking wire and the power receiving head are improved, and the insulating housing combination guiding groove is improved. , guide bars, springs, the application of complex structures such as α-type metal shrapnel, etc.

And, it is considered to provide a terminal device provided with a limiter; the limiter has a first space and a second space, and at least two parallel wires can be inserted into the casing to respectively combine the mechanisms of the metal dome. Or further enabling the switch wiring device to allow a person to directly operate the wire into the pivotal connection head without using a tool, and to have the conductive head and the auxiliary fixed metal dome under the condition of high rigidity or high hardness. And guiding the metal shrapnel movement path and other means. None of these topics have been specifically taught or disclosed in the above references.

Therefore, the main purpose of this creation is to provide a switch wiring improvement device, which provides an easy operation and increases the stability of the operation movement under the condition of compact structure. The utility model comprises a conductive element fitted in the insulating housing, a switch button for combining the conductive elements and a power receiving head.

Referring to Figures 1 and 3, the switch wiring improvement device of the present invention comprises a combination of an insulative housing and a switch button; respectively, indicated by 10 and 20. The housing 10 has a chamber 11 for receiving the switch button 20; the switch button 20 is combined with a conductive member 30 and a spring 35 (this portion is of a prior art and is not described in detail). According to the direction of FIG. 1, the housing 10 is provided with a wire insertion hole 12 communicating with the chamber 11 at the lower end regions of the two sides, and a wiring circuit or wire 90 for the electronic or electrical equipment is inserted into the housing chamber 11, and the connection terminal 40 is combined. .

Basically, the present switch wiring device is selected to allow at least two juxtaposed wires 90 to be inserted into the casing 10 in accordance with the practical application type, and the structure of the power receiving head 40 is combined as an illustrative embodiment. That is, one of the power connectors 40 can be pivotally connected to the shape of at least two wires 90 or 95.

Two electrical terminals 40 are shown disposed within the housing chamber 11; each electrical connector 40 includes a limiter 50 and two portions of the contacts 60 of the connection limiter 50. The restrictor 50 selects a material having a high rigidity or hardness (for example, iron, steel, etc.) to form a slab billet, and causes the restrictor 50 to form a rectangular frame structure shown in FIG. 1 from the form of the slab billet. And the combination of the contacts 60.

The figure also depicts that the limiter 50 has a first side 51, a second side 52 connecting the first side 51, a third side 53 connecting the second side 52, and a fourth side 54 connecting the third side 53, connecting the fourth A portion of the side 54 and the fifth side 55 extending in the direction of the second side 52, together with a rectangular frame structure, accommodates a metal dome 70.

In the adopted embodiment (see FIGS. 2-1 to 2-5), at least one of the first side 51 and the fifth side 55 (as shown in FIG. 2-1) faces the third side. The direction of 53 is bent to extend to form a first secondary side 56 (for example, an angle between the first side 51 and the first secondary side 56 forming an acute angle, a right angle or an obtuse angle), and the fifth side 55 and the first side 51 are in the same position. In the plane, the fifth side 55 can be further bent in the direction of the third side 53 to extend to form the second secondary side 57 (as shown in Figures 2-1 to 2-5, the fifth side 55 and the second side are made The secondary side 57 forms an acute angle, a right angle or an obtuse angle, and the first secondary side 56 and the second secondary side 57 are parallel and juxtaposed; thus, the restrictor 50 can be divided into a first space 58 and a second space. Structure of 59.

2-2 to 2-5 particularly depict the formation of a gap s between the first secondary side 56 and the second secondary side 57 due to the bending operation, and the absence of the gap s (Fig. 2-2). situation. Further, in FIGS. 2-4 and 2-5, the first secondary side 56 is protruded toward the second secondary side 57 to form a first convex portion 56a, and the second secondary side 57 faces the first secondary side. A second protrusion 57a is formed in the direction of the 56; the first protrusion 56a and the second protrusion 57a are used to compensate or reduce the gap s between the first side 56 and the second side 57 to reduce the operation. When the metal dome 70 moves, the first secondary side 56 and the second secondary side 57 are not caused to cause too much bias or sway, and the role of the normal movement of the metal elastic piece 70 is established; and the above gap s exists. The first secondary side 56 and/or the second secondary side 57 may be provided to maintain proper elasticity to accommodate slight deflection of the metal dome 70 during the transition and frictional engagement with the first secondary side 56 and/or the second secondary At the side 57, a moderate off-card margin can be provided.

In the embodiment taken, the contact piece 60 has a first end 61 and a second end 62; the first end 61 corresponds to the first side 51 and the fifth side 55 of the limiter (or the first space 58, the second space 59) a second fork portion 61a and a second finger portion 61b are respectively connected to the first side 51 and the fifth side 55 of the restrictor, and the second end 62 is inclined and tilted to face the conductive element. The direction of 30 extends. The switch button 20 controls the conductive element 30 to selectively energize or de-energize the second end 62 of the contact.

In detail, when the person presses the switch button 20, the conductive member 30 is driven to contact or leave the contact piece 60 or the contact second end 62, so that the power receiving head 40 is energized or de-energized.

The metal dome 70 is also shown to resemble a "V" shaped body having an opening, including a first segment 71, a second segment 72, and a curved segment 73 connecting the first segment 71 and the second segment 72. The first segment 71 has a combined end portion 74 of a tip end 74 and a hole type, which can be combined on the combined portion 53a of one of the convex portions of the third side 53 of the restrictor, so that the first segment 71 of the metal dome is positioned at the limiter. 50; and, the head end 74 of the first section 71 of the metal dome and the upper end of the third side 53 of the restrictor are fixed together in a groove portion 13 of the housing chamber 11. And, the metal dome bending section 73 is wound around the column pile 14 of the housing chamber 11, so that the metal elastic piece second section 72 projects into the limiter 50 to form a swingable shape.

In detail, the second segment 72 of the metal dome has a fork structure and has a first leg portion 78 and a second leg portion 79 that are respectively received or protruded into the first space 58 and the second space 59 of the restrictor. Moreover, at least the second side 52 and the first secondary side 56 of the limiter assist the specification of the path of movement of the first leg portion 78 of the metal dome, and the fourth side 54 and the second side of the limiter 57 assist the specification of the metal spring second leg portion 79. The path of motion. It can be understood that, as described above, the second side 52 of the restrictor, the first secondary side 56, the fourth side 54 of the restrictor, and the second secondary side 57 cooperate with the structure of the gap s to allow the limiter 50 to have an elastic margin. Reducing the frictional jam between the second side 52, the first secondary side 56 and the metal spring first leg 78, the fourth side of the restrictor 54, the second secondary side 57, and the second spring portion 79 of the metal dome, but Increase the smoothness of the movement of the metal dome 70.

In the embodiment taken, the metal dome 70 is fitted behind the housing chamber 11 with its opening arranged in the direction of the conductive element 30 such that the configuration of the second segment 72 facilitates the insertion of the wire 90 or 95; and, the wire The 90 or 95 insertion direction or angle is about the same as the angle of inclination of the first end 61 of the contact (the first finger 61a or the second finger 61b) such that the wire 90 or 95 and the first end 61 of the contact (the first finger) The 61a or second finger 61b) forms a larger contact area than the conventional structure, and closer to the conductive member 30, also increases the conduction efficiency and the combined stability. It is obviously different from the conventional art application type of α-type metal shrapnel or screw mechanism locking wire.

Figures 3 and 4 specifically show that a person directly operates a single wire 90 or two parallel wires 90, 95 are inserted into the wire hole 12 and the limiter 50, and the tail end of the metal spring first leg 78 presses the wire 90 against The first finger portion 61a of the sheet is formed in an on state; the tail end of the second leg portion 79 of the metal dome presses the wire 95 against the second finger portion 61b of the contact piece to form a conductive state. At this time, the conductive member 30 is in a position in contact with the second end 62 of the contact piece to form an energized state. If the person presses the switch button 20 to drive the conductive member 30 to move downward in the figure to cause the conductive member 30 to leave the second end 62 of the contact, a power-off state is formed.

Referring to Figures 3 and 4, the structural form in which the metal dome 70 is received in the restrictor 50 is depicted, at least the second side 52 of the limiter and the first secondary side 56 collectively regulate the movement of the first leg 78 of the metal dome. The path is not yawed to the sides; the fourth side 54 and the second side 57 jointly define the path of movement of the second leg portion 79 of the metal dome without yawing to the sides; this helps to increase The movement of the metal dome 70 and the operation of the metal dome 70 combine the stability of the wires 90 and/or 95.

In particular, when the operating wires 90 and/or 95 are inserted into the first space 58 and/or the second space 59 of the housing chamber 11 and the restrictor 50, the wires 90 and/or 95 are limited to the first limit of the high hardness limiter. In the space 58 and/or the second space 59, there is no case where the bare metal end of the conventional technical wire is inserted or scraped, or because of the operating environment, occasions (for example, vibration of the machine equipment, etc.) or Inadvertent collision, causing the wire to swing excessively inside the casing, twisting, etc., and expanding the casing.

Figures 3 and 4 also show that the human operable tool 80 extends from the lower end of the housing 10 into the chamber 11 and the restrictor first space 58 or the second space 59, pushing the metal spring first foot 78 or The second leg portion 79 causes the tail end of the first leg portion 78 or the tail end of the second leg portion 79 to leave the wire 90 or 95, and the second portion 72 of the metal spring piece is released from the state of the wire 90 or 95, so that the person can directly remove the wire. 90 or 95 leaves the housing 10.

Referring to Figure 5, the limiter 50 and the contact piece 60 form an integrally formed structure. That is, the first finger portion 61a of the first end 61 of the contact piece and the first side 51 of the restrictor are integrally connected, and the second finger portion 61b is engaged with the structural form of the fifth side 55 of the restrictor.

Referring to FIG. 6, in a possible embodiment, according to the shape of the housing chamber 11, the second side 52 and the fourth side 54 of the restrictor 50 are formed with recesses 52b, 54b formed in the housing 10 in a reliable manner. Or the shoulder 16 on the chamber 11 makes the combination of the restrictor 50 and the housing 10 more stable.

Referring to Figures 7 and 8, a modified embodiment of the power head 40 is disclosed. According to the combination of the housing 10 (or the chamber 11) and the switch button 20, the second end 62 of the contact of the power head 40 faces the limiter 50 (or the first space 58, the second space 59 or the lower part of the figure Or the direction of the opening of the metal dome 70 is bent to form a secondary end 63 (for example, the second end 62 and the secondary end 63 form an acute angle, a right angle or an obtuse angle); and from the secondary end 63 toward the conductive element 30 Or the direction of the switch button 20 is bent to extend to form a trailing end 64 (e.g., such that the secondary end 63 and the trailing end 64 form an acute angle, a right angle or an obtuse angle).

Figure 8 shows that when a person operates the switch button 20 to drive the conductive member 30 to the lower side of the figure, the conductive member 30 touches the tail end 64 of the sheet to form an energized state. If a person operates the switch button 20 to move the conductive member 30 upwardly in the figure, the conductive member 30 will leave the contact tail 64 to form a power-off state.

Typically, this switch wiring improvement device has the following advantages compared with the old method in that it has the trend of not increasing the housing volume and conforming to the miniaturization design of the switch terminal device: 1. The structure of the housing 10, the switch button 20, the conductive member 30 and the limiter 50, the contact piece 60, the metal dome 70, and the like have been redesigned. For example, the limiter 50 includes a first side 51, a second side 52, a third side 53, a fourth side 54 and/or a fifth side 55; the first side 51 is bent to form a first secondary side 56, a fifth side 55 is bent to form a second secondary side 57, and a frame structure having a first space 58 and a second space 59 is jointly formed to receive the first leg portion 78 and the second leg portion 79 of the metal dome 70; the metal dome 70 has The first segment 71 is fitted or connected to the third side 53 of the restrictor, and the curved portion 73 is wound around the stud 14 of the housing 10 such that the first leg portion 78 and the second leg portion 79 of the second segment 72 are standardized in the limiter. The first space 58 and the second space 59 move, and the personnel directly operate the wires 90 and/or 95 to be inserted into the chamber 11, and are respectively pressed by the metal elastic first leg portion 78 and the second leg portion 79 on the limiter 50. The first end portion 61a and the second end portion 61b of the first end 61 are respectively connected with the first side 51 and the fifth side 55 of the limiter, and the second end is connected. 62 and the conductive member 30 form a contact or non-contact type and the like, which is significantly different from the conventional one, and also changes its use and operation type, and is different from the old method. 2. In particular, the old method must be used for the disassembly and assembly of the wiring circuit or the wire. It is necessary to operate the screw to lock and loosen the troublesome operation. When the screw is in the released state, the screw will be deflected, causing the personnel to operate the screw to align the locking wire and The operation of the power receiving head becomes troublesome and difficult, or the application of the α-type metal dome, the guiding groove and the guide bar and the spring-fitted structure on the insulating housing and the power receiving head make the structure more complicated and increase the manufacturing cost. And the volume of the casing, or the vibration of the machine equipment, causing the screws to loosen, causing the wire to loosen, etc., have been significantly improved. 3. The electrical connector 40 has the functions of good electrical conductivity, auxiliary fixed metal elastic piece 70 and guiding metal elastic piece 70 under the condition of high rigidity or high hardness. Moreover, the limiter 50 corresponds to the structure for accommodating the metal dome 70 and the wires 90 and 95, and not only provides the user's simple operation, but also improves the bare metal insertion of the old method wire or causes the metal dome to yaw and scrape. Broken shell, unstable clamping, etc. 4. The limiter 50 forms a first space 58 , and the second space 59 corresponds to the metal spring first leg portion 78 and the second leg portion 79 , so that the second side 52 , the first secondary side 57 , and the fourth side 54 . The second secondary side 58 defines the motion paths of the first leg portion 78 and the second leg portion 79, respectively, and allows the disassembly and assembly of the different or juxtaposed wires 90, 95 to provide a structural design that is more desirable than the prior art.

Therefore, this creative department provides an effective switch wiring improvement device, its spatial type is different from the well-known, and has the advantages unmatched in the old law. It shows considerable progress, and it has fully complied with the new type. The requirements of the patent.

However, the above is only a feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications made by the scope of the patent application of the present invention are covered by the scope of the creative patent. .
