telecommunications, such as splices, termination panels, power dividers, and wavelength division multiplexers.

It is often preferred that telecommunication boxes be re-accessible. The term reaccessible means that the telecommunication boxes can be reopened to allow access to the telecommunication components housed in them, without the need to remove and destroy the telecommunication boxes. For example, certain telecommunications boxes may include separate access panels that can be opened to access the insides of the boxes, and then closed to reseal the boxes. Other telecommunications boxes are in the form of elongated sleeves formed to wrap covers or half shells that have longitudinal edges that are attached by clamps or other retainers. Still other telecommunication boxes include two half pieces that are attached to each other through clamps, wedges or other structures. Telecommunication boxes are typically sealed to inhibit the entry of moisture or other contaminants.

Detailed description of the invention

FIG. 1 is an exploded view of a splice confinement assembly 100 that includes a base 101 and

INSTITUTO MEXICANO OF LA FRQFIEDAf »NWOSTWIAL ~ * a cover 102 that cooperate to form a box 103 defining an interior 104. Locking systems 105 detachably fix cover 102 in a closed position with respect to base 101. The locks 105 may be released to allow cover 102 to be removed from base 101. A splice tray assembly 106 is mounted within Interior 104 of box 103. Several cable port assemblies 107, 108, 109 are arranged in the cable ports defined by box 103 to allow the fiber optic cables to run into and out of box 103.

In particular, a first input cable port assembly 107, a second input cable port assembly 108, and a plurality of output cable port assemblies 109 are arranged in box 103. In the example shown, the box 103 includes a first cable entry port assembly 107, a second cable entry port assembly 108, and five cable exit port assemblies 109. In some implementations, box 103 may include multiple first cable entry port 107 assemblies and / or multiple second cable entry port assemblies 108. In still other implementations, box 103 may include more or fewer cable entry assemblies. cable outlet port 109.

As used herein, the terms entry and exit are used for convenience and are not

<img file="MX339488B_D0016.tif" />

intended to be exclusive. The optical signals carried through the optical fibers can travel in one or both directions. Accordingly, fiber optics cloned through any of the cable entry port assemblies 107, 108 can conduct input and / or output signals. Similarly, the optical fibers routed through the cable exit port assemblies 109 can carry input and output signals.

The optical fibers introduced into box 103 through the input cable port assemblies 107, 108 are optically coupled to the optical fibers inserted into box 103 through the cable output port assemblies 109. For example, the optical fibers may be coupled to each other in splice tray assembly is 106 as will be described in more detail here. In certain implementations, one or more of the optical fibers can also be directed to a splitter (see Figure 38) as described in more detail here. Fibers leaving the splitter can be routed to splice tray assembly 106.

As shown in Figures 2-9, case 103 has an upper part 110, a lower part 111, a first side 112, a second side 113, a first end 114, and a second end 115. The port assemblies of cable 10725 109 are arranged in the cable ports on the first ¹⁶ IMPI?

INDUSTRIAL end 114 of box 103. The second nfi Hq box 103 is generally robust (ie does not define cable ports). Base 101 forms Bottom 111 of box 103 and cover 102 forms top 110 of box 103. Base 101 forms most of first end 114 of box 103 and cover 102 forms most of second end 115 of box 103. Base 101 and cover 102 cooperate to form sides 112, 113 of box 103.

Base 101 Includes a Bottom surface 142, a back wall 143, and side walls 144 extending upward from the Bottom surface 142 and forward of the rear wall 143 to a front wall. The sides 112, 113 of the base 101 (i.e. the side walls 144) are i5 higher towards the first end 114 and shorter towards the second end 115 of the box 103. The higher parts and the first end 114 of the base 101 provide protection to the cable port assemblies 109 when the cover 102 is removed from the base 101. The shorter and second end 115 sides of the base 101 facilitate access to the assembly of splice tray 106 when cover 102 is removed from base 101. In certain implementations, the side walls of the base 101 remain cut along a greater part of the length of the splice tray assembly 106. In one implementation, the side walls

INDI / miAl of base 101 remain short along the length of splice tray assembly 106.

A gasket or sealing ring 116 (Figure 32) is provided between base 101 and cover 102 around the perimeter of box 103. Gasket 116 prevents dirt, water, or other contaminants from entering box 103 when cover 102 is secured to base 101 with latches

105. In some implementations, base 101 defines a gasket channel 117 in which gasket 116 can be seated. In certain implementations, cover 102 forms a tongue

118 extending down into the cover in alignment with gasket channel 117. When cover 102 is disposed on base 101, tab 118 compresses gasket 116 into channel 117. In other implementations, cover 102 may define a second channel in place of tongue 118 to accommodate gasket 116. In still other implementations, cover 102 can define the channel and base 101 can define the tongue.

As shown in Figure 9, gasket channel 117 extends along the perimeter of box 103 on a non-flat path. Base 101 walls are taller at first end 114 of box 103 and smaller at second end 115 of box 103. Higher walls at first end 114 define a first plane along which it extends a first section 120 of the joint channel 117 and

IMPI

INSTITUTO MEXICANO Di LA PROPIEDAD INDUSTRIAL the Lower walls at the second end 115 define a second plane along which a second section 121 of the joint channel 117 extends. The walls pass between the first and second planes to define a section transition joint 122 of the channel joint 117. In the example shown, the base walls transit on each side 112, 113 of the box 103 to define two transition sections

22.

In some implementations, the first section 120 of the joint channel 117 defines a greater part of the joint channel 117. For example, the first section 120 of the joint channel 117 extends along a greater part of the lengths of the box 103. In other implementations, the second section 121 and / or transition section 122 may define most of the joint channel 117. In some implementations, transition section 122 has a non-planar outline. For example, in the example shown, the transition section 122 is contoured with a convex slope (see Figure 9). In other Implementations, transition section 122 is flat, but forms an angle relative to the first and second planes.

In some implementations, gasket channel 117 defines tabs 119 (Figures 28-32) that aid in retaining gasket 116 within gasket channel 117. For example, tabs 119 can help retain gasket.

In some implementations, the tabs 119 have been rounded. In other implementations, the tabs 119 may be of any suitable shape (eg, triangular, rectangular, etc.). In certain implementations, flanges 119 extend between a Lower portion of channel 117 and an upper portion of channel 117. In the example shown, flanges 119 extend at a non-orthogonal angle to the Lower surface of channel 117.

As shown in Figures 1 and 12-14, the cover

102 it is attached to base 101 using latch arrangements 105. For example, in certain implementations, each latch arrangement 105 is configured to removably latch cover 102 to base 101. Each latch arrangement 105 includes a clamp element. 123 and at least one tension member 127. In the example shown, each clamp member 123 includes two tension members 127. One end of tension member 127 engages base 101 and the opposite end of tension member 127 connects to clamp member 123 (eg, through a passage or recesses in clamp member 123).

In certain implementations, tension member 127 is configured to pivot relative to base 101 to

Tension member 127 is also configured to pivot relative to clamp member 123 to allow clamp member 123 to engage cover 102. In particular, clamp member 123 is configured to rotate relative to tension member 127 between an unlocked position (see figure 12C) and a hold position (figure 13) as will be discussed in more detail here.

In some implementations, at least one latch member 105 is disposed on each side of the case 103. In certain implementations, the clamp members 123 of the latch members 105 cover a greater part of the perimeter of the cover 102. In the Example shown, two latch members 105 are arranged on each side 112, 113 of the box and a latch member 105 is arranged on each end 114, 115 of the box 103 (eg see Figure 2). In other implementations, however, a larger or smaller number of hook members

one 05 can be arranged on each side 112, 113 and / or at the end

114, 115. In some implementations, the clamp element 123 has a generally trapezoidal shape, the stop section 124 being formed on the longest side and the grip section 125 on the shortest side. Members of

Vertical notches 136 lead to vertical recesses 139 defined in the side walls. 138. Notches 136 and recesses 139 are shaped and sized to accommodate tension members 127. Two raised structures 137 are disposed on opposite sides 112, 113 of the upper surface 130. Each of the relief structures 137 extends from the perimeter of the box 103 into the Inner channel 132. The raised structures 137 are shaped to accommodate the shape of the clamp members 123 when the clamp members 123 are secured in the cover 102. In the example shown, the raised structures 137 have angled sides that ²² IMPI

INDUSTRIAL extend along the angled sides of adjoining caliper mlombrec 123 (see figure 13).

The clip members 123 of the hook members 105 are configured to fit the cover

102. Each 123 caliper element Includes a stop section

124, a grip section 125, and the notches 126 (see figure 12A). In some implementations, the grip section 125 is provided on an opposite side of the clamp member 123 of the stop section 124. The notches 126 are arranged io on the same side of the clamp member 123 as the stop surface 124. In certain implementations, the stop section 124 defines a generally S-shaped contour (see Figure 12A). For example, the stop section 124 defines a concave section 124A extending downward from the upper surface of the clamp member 123 and a convex surface 124B extending downward from the concave surface 124A.

The tension member 127 of each latch member 105 includes two legs 128 connected at a first end 20 129. In certain implementations, the legs 128 of the spring members 127 are connected at both ends. The first end 129 of tension member 127 is disposed within a downward facing recess 141 in base 101 (see Figures 12B and 12C). The recess 141 allows the legs 128 of the tension member 127

IMPI

INSTITUTO MtXICA / H, di LA mWlEDAD INXrSTRMt pivot around the first end 129 between the secured position and the released position. The second end of tension member 127 extends toward clamp member 123 to allow clamp member 123 to pivot around the second end.

To engage cover 102 to base 101, legs 128 of tension member 127 are pivoted upward until gripper member 123 is moved to a position adjacent to cover 102. Clamp member 123 is positioned so that that the convex section 124B of the stop section 124 is disposed in the outer channel 134 of the upper surface 130 of the cover 102 and the grip section 125 extends upward from the upper surface 130 (see Figure 12C). The outer lip 135 fits within the concave section 1 24A of the stop section 124 of the clamp member 123. When the stop section 124 is disposed in the outer channel 134, a user pushes the grip section 125 towards the upper surface 130 of the cover 102, thereby causing the clamp member 123 to pivot around the convex surface 124B of the stop section 124.

When the clamp member 123 has been pivoted to the locked position (FIG. 13), the grip section 125 is disposed on the inner channel 132. The clamp member 123 tapers inward from the stop section 124 toward clamping area 125. Accordingly, gripping section 125 is spaced upward a distance from the surface of Inner channel 132. The distance is sufficient to allow a user to grasp the grip section 125 by inserting the fingers into the space above the inner channel 132. Accordingly, a user can disengage the clamp member 123 from the cover 102 by lifting the grip section 105, thereby causing the clamp member 123 to pivot 10 around the convex surface 124B of the stop section 124 until grip section 125 extends upward from cover 102.

Figures 33-46 illustrate an implementation example of the splice tray assembly 106 isolated from the box.

103. Splice Tray Assembly 106 Includes a base plate 180 on which one or more slotted plates 160 are arranged. Each slotted plate 160 is configured to contain one or more splice trays 150. In certain implementations, the base plate 180 may also be configured to contain one or more splice trays 150. In the example shown, base plate 180 is configured to store two splice trays 150 and four slotted plates 160. Each slotted plate 160 in the illustrated example has nine splice trays 150.

In other implementations, however, the 180 baseplate

may have a larger or smaller number of slotted plates

160 and each slotted plate 160 may have a greater or lesser number of splice trays 150.

As shown in Figure 34, the base plate 180 includes side walls 182 that extend upward from a bottom surface 181. One of the side walls 182 defines a plurality of openings 183 and the other of the side walls 182 defines a plurality of elastic tabs 184. Each of the tabs 184 has a latch 185 that extends inward from the tab 184. Each latch 185 defines a ramp that tapers outward as the ramp extends to the bottom surface 181. Each latch 185 defines a shoulder to the bottom surface 181. Each tab 184 is configured to flex outward to move the latch 185 out of the openings 183. Each tab 184 can be moved Independently from the other tabs

In certain implementations, the channels of the first retaining arrangement 187 are sloped down toward the bottom surface 181. The second retention arrangement 188 Includes fingers of retention that form a passage channel. In certain implementations the detent fingers are spaced far enough apart to form a gap at the top of the second detent arrangement 188.

In some implementations, the base plate 180 is configured to support the splice trays 150. For example, in certain implementations, the base plate 180 also defines a recess 186 that will be described in more detail here. In certain implementations, the baseplate 180 defines one or more splice tray mounting structures 189 in each of which a splice tray 150 can be pivotally attached. In certain implementations, the splice tray mounting structures 189 are arranged on a raised platform above the bottom surface 181. In Example 25 shown, the base tray 180 includes two 'NDUSTRMl' structures

splice tray assembly 189 arranged on a raised platform adjacent to landing 186.

One or more slotted plates 160 (Figures 35-39) can be attached to the base plate 180 (eg, see Figures 40-42). Each 160 slotted plate includes a base

161 having side walls 162. In some implementations, a single grooved plate 160 is dimensioned to extend over a greater part of the length of the base plate 180. In other implementations, however, multiple grooved plates 160 are arranged so length of base plate 180 (see figure 33). Each grooved plate 160 is dimensioned such that the outer surfaces of the side walls 162 abut the inner surfaces of the side walls of the base plate 182 when the grooved plate 160 is disposed on the base plate 180. Hitch tabs 163 (figure 33) are arranged on one of the side walls

162 and hooking shoulders 164 (figure 35) are arranged on the other of the side walls 162.

To attach the slotted plate 160 to the base plate 180, the latch tabs 163 of the slotted plate 160 are inserted into the openings 183 of the base plate 180.

160 The latch shoulder 164 is pivoted to move over the ramp defined by the latches 185 of the flexible flanges 184, thereby bending the flanges 184 outward. When the slotted plate 160 has been pivoted enough so that the latch shoulders 164 release the latches 185, the flexible tabs 184 close in position again so that the latches shoulders 185 adjoin the latch shoulder 164 of the slotted plate 160. To release the slotted plate 160 from the base plate 180, a user flexes the tabs 184 outwardly from the slotted plate 160 until the engaging shoulder 164 of the slotted plate 160 releases the shoulders of the latches 185 from the tabs 184.

Each grooved plate 160 includes one or more splice tray mounting structures 167 in which splice trays 150 may be pivotally coupled to slot plate 160. In certain implementations, splice tray mounting structures 167 are arranged in a row in the center of the slotted plate 160. Each slotted plate 160 also includes structures for guiding the optical fibers of the base plate 180 to the splice trays 150. For example, in certain Implementations, each slotted plate 160 includes tube feed guides 165 and fiber feed guides 166 for each construction structure.

In some implementations, one or more of the fibers received in the first retention arrangement 187 may be routed to an optical splitter 192 where the io optical signals carried by the fibers 193 are divided into a plurality of optical fibers 194. The Figure 38 shows an exemplary optical splitter 192 disposed in a splitter assembly area 171 in a cavity 170 defined in the Bottom of the slotted plate 160. In the example shown, a single divider 192 is arranged in the assembly area of ​​divider 171. In other implementations, however, more or less number of dividers 192 may be arranged in cavity 170. In the example shown, the divider 192 is postcloned at one end of slotted plate 160.

An inlet opening 172 is defined through the top surface 161 of the slotted plate 160. Inlet fibers of the divider 193 are directed from the top surface 161 of the slotted plate 160, through the inlet opening 172, toward the divisor 192.

Each of the openings 173 is elongated in the direction that extends between the sides 162 of the slotted plate 160. In certain Implementations, the top surface 161 defines ramps 174 leading to the outlet openings 173. In the example shown, nine outlet openings 173 extend through top surface 161. In other implementations, however, top surface 161 may define more or fewer outlet openings 173. In certain implementations, the outlet of openings 173 are

arranged on two or more of the tube guides 167 of the slotted plate 160.

Two or more exit fibers from divider 194 extend from divider 192 toward exit from openings 173. One or more radii of curvature limiters 176 are provided to aid in the separation of exit fibers from divider 194 around the cavity 170 towards outlet openings 173. In some implementations, the radii of curvature delimiters 176 are positioned to provide a first path of expansion 177 extending from divider 192, along a first end of slotted plate 160, beyond the row of outlet from openings 173, around a bend radius limiter

As shown in Figures 38 and 39, in certain Implementations, a retention arrangement 175 is provided at each outlet opening 173. Each retention arrangement 175 defines a slot aligned with the outlet opening 173 that guides the outlet fiber of the respective divider 194 through the opening 173 and onto the top surface 161 of the slotted plate 160 (see Figure 39).

Each slotted plate 160 includes one or more splice tray mounting arrangements 167 on which splice trays 150 are mounted. In certain implementations, each splice tray mounting arrangement 167 includes a hinge bracket through the which a hinge pin of a corresponding splice tray 150 is inserted to pivotably engage grooved plate 160. Base plate 180 may also include one or more splice tray mounting arrangements 189. Optical fibers received in base plate 180 are directed through slotted plates 160 toward splice trays 150.

Figure 45 shows an example of a splice tray 150 suitable for use with the ranüri and / or base plate 180 described above. The front of each splice tray 150 includes a splice area 151 in which two or more optical fibers can be optically coupled to each other. Each splice tray 150 also includes a first inlet 152 through which at least a first fiber optic enters splice tray 150 and a second inlet 154 through which at least a second fiber optic enters the splice tray 150. In certain implementations, inlets 152, 154 are located adjacent to the hinge pin of splice tray 150, but point in different directions. For example, the first inlet 152 of each splice tray 150 can be aligned with a corresponding one of the fiber directing guides 166 and the second inlet 154 can be aligned with a corresponding one of the tube directing guides

165.

The first inlet 152 guides the fibers over the splice tray 150 along a first direction, and the second inlet 154 guides the fibers over the splice tray 150 along a second direction. The optical fibers entering splice tray 150 at second inlet 154 cross the optical fibers entering

The front of each splice tray 150 also includes a first declining channel 157 for the fibers extending through the first inlet 152 and a second declining channel 156 for the fibers extending through the second inlet 154. The re-cloning channels 156, 157 guide the fibers from the entrances 152, 154 to the junction zone 151. In certain implementations, the first re-cloning channel 157 extends from the first inlet 152, along a recessed channel 153, and into the first re-cloning channel 157 that guides the fibers around one or more reel 158 arranged in a central portion of splice tray 150. In the example shown, the first straddle channel 157 is wrapped around two fiber spools separated in the middle by a slit to allow the fibers to be wound in a "number 8" configuration.

The second declining channel 156 extends from the second inlet 154, through an upper part

of the recessed channel 153, and in a helical outer channel located on an outer edge of the splice tray 150. The helical channel 156 guides the fibers around the splice tray 150 and opens in the first directional channel 156 in one direction opposite the first inlet 152. In some implementations, the routed optical fibers in the splice tray of the second inlet 154 are arranged in a loose tube 195 (see Figure 46). One or more retention fingers 155 are provided at second inlet 154 and along helical targeting channel 156 to assist in retaining tube 195.

In the example shown in Fig. 40, splice trays 150 are arranged in a row with a first splice tray 150A at a first end and another splice tray 15 at a second end. Each splice tray 150 is pivotally mounted to the respective slotted plate 160 or base 180 so that each splice tray 150 can be pivoted separately between a rest position and an unlock position. When in the home position, each of the splice trays 150 is oriented such that the front of tray 150 generally points toward the first splice tray 150A. In certain implementations, the front of splice tray 150 also points at least partially toward

In the example shown in Figures 40-43, all splice trays 150 are arranged in the home position. Each splice tray 150 rests on the splice tray 150 behind it. The rear of splice tray 150N at the second end of the row rests on recess 186 in base plate 180. Recess 186 maintains splice trays 150 in the home position. The first splice tray 150A is accessible to a user. No splice tray 150 blocks access to the first splice tray 150A and the front of the first splice tray 150A partially points up. In some implementations, the splice trays define a rounded edge 159. For example, as shown in Figure 44, the perimeter along the back side of each splice tray 150 may have a rounded contour 159. The rounded contour can improve the movement of splice trays 150 between rest and unlock positions.

To access an additional selected splice tray 150 along the row, all splice trays 150 facing the selected splice tray 150 are moved to the unlock position and the selected splice tray 150 remains in the rest position. Accordingly, there are no splice trays 150 blocking access to the selected splice tray 150 and the front of the selected splice tray 150 partially points upward.

Splice tray assembly 106 is configured to be disposed within base 101 such that row of splice trays 150 extends between first end 114 and second end 115 of box 103 (see Figure 1). In the example shown, splice trays 150 are oriented such that the front of each splice tray 150 is generally oriented toward the second end 115 of the box when it is in the home position. In certain implementations, the front of each splice tray 150 also points in part toward cover 102 when it is in the home position. In other implementations, however, splice trays 150 may be oriented to generally point in a different direction from box 103.

As shown in Figures 10 and 11, a buffer strip 190 can be arranged under cover 102 to help retain splice trays 150 in the home position, while cover 102 is attached to base 101. Damping strip 190 extends along the length of deck 130 of deck 102 between first end 114 and second end 115. The buffer strip 190 is thick enough to contact the tops of splice trays 150 when splice trays 150 are arranged in rest positions and cover 102 is attached to base 101. In certain implementations , the cushioning strip 190 is formed from foam or resin. In other implementations, however, the buffer strip 190 may be formed of any elastic material or a material otherwise capable of retaining splice trays 150 in position.

Referring to Figures 47-61, the optical fibers are routed to the splice assembly 106 in box 103 through cable ports 145-147. Conduits 200 extend through first end 114 of base 101 to define cable ports 145-147. For example, a first conduit 201 extends through first end 114 on first side 112 to define round entry port 145, a second conduit 202 extends to ιμρι ^ 5 Mexican property iNsrrnrrc through first end 114 in the first I to So *¹**! 1 Z * -to define the oblong entry port Í46; and multiple conduits 203 extend through first end 114 on second side 113 to define outlet ports 147.

In the example shown, five conduits 203 extend through the first end 114 to define the five outlet ports 147. One of the outlet conduits 203 is located on the first side 112 of the base 101 above the second conduit 202.

As shown in Figure 47, each of the conduits 200 has a first end that partially extends into the interior 104 of the box 103 and a second end that partially extends out of the box 103. By the arrangement of a portion of each duct 200 is within the interior of the box 104, an overall length of the box 103 is reduced compared to a box having ducts 200 extending only outside the box 103. In some implementations, approximately half of each conduit 200 is disposed within interior 104 and about half is disposed outside of enclosure 103. In other implementations, most of each conduit 200 may be disposed within interior 104 or outside the box 1 03.

In some implementations, a cut seal member 209 is provided in one or more of conduits 200.

The sealing members 209 are connected to the conduits with weak bands or other frangible connections that facilitate removal of the sealing members 209. of the conduits 200. Accordingly, the sealing members 209 temporarily seal the conduits 200 until the cable port is needed. In certain implementations, the sealing members 209 are configured to come off cleanly (eg, with pliers). Additional information regarding examples of implementations of sealing members 209 is provided in Annex A, attached at the end of this description. The description in Annex A is incorporated herein by reference in its entirety.

In some implementations, the first conduit 201 and the outlet of conduits 203 are round. However, the first conduit 201 is smaller than the output of conduits 203. In some implementations, the first conduit 201 is sized to receive an input cable having one or more optical fibers, and the output conduits 203 are sized to receive multiple fiber optic tubes from one or more optical cables. In certain implementations, the second conduit 202 is generally oblong. In some implementations, second conduit 202 is sized to receive two input cables, having

In other implementations, however, each of the conduits 200 may be dimensioned to receive more or less fiber optic cables.

Figures 49-53 show a first exemplary assembly, port 107 is suitable for sealing one or more fiber optic cables entering the box through round entry port 145. The first exemplary orifice assembly 107 includes a body 210 extending between a first end 211 and a second end 212. Port body 210 defines a through passage 213 that is extending between the first and second ends 211, 212.

the optical fibers may be held in tapes or may have no buffer tubes. In some implementations, fiber optic cable 220 also includes additional reinforcing members (eg, aramid yarn) 224.

The reinforcing member retention arrangement 214 provides the structure to which the reinforcing elements 223, 224 of the fiber optic cables 220 can be anchored to secure the cable 220 to the first port assembly 107. The retention arrangement 214 It includes a flange 215 defining a recess 219 in which a central reinforcing member 223 of cable 220 can be disposed. Reinforcing element 223 can be held in recess 219 with epoxy or other adhesive. Inclination of cable 220 through displacement opening 218 at first end 211 of port body 210 guides the cable to one side of second end 212, thereby facilitating adhesion of reinforcing element 223 within recess 219.

The reinforcing member retention arrangement 214 also includes two teeth 216 that extend outwardly from flange 215 generally parallel to the longitudinal axis of port body 210. Teeth 216 are angled to form a narrow channel therebetween. A wall 217 extends through at least part of the channel. For example, in some implementations, wall 217 extends from flange 215 to one end of teeth 216. In others

<img file="MX339488B_D0041.tif" />

Implementations, however, wall 217 extends over only part of the height of the teeth (see figure 50). To secure a cable 220 to port body 210, additional reinforcing members 224 of cable 220 can be wound (eg, one, two, or three times) around flange 215 and slide between teeth 216 toward the flange. 215 (see figure 53).

The wall 217 between the teeth 216 is brittle enough to allow the reinforcing members 224 to cut or cut a slot through the wall 217 so that the reinforcing elements 224 are captured in the slot. For example, in one implementation, wall 217 is significantly thinner than teeth 216. In some implementations, wall 217 has a thickness ranging from about 0.25mm to about 0.7mm. In certain implementations, wall 217 has a thickness ranging from about 0.35mm to about 0.5mm. In certain implementations, wall 217 is approximately 0.3 mm thick. In certain implementations, wall 217 is approximately 0.4 mm thick. In certain implementations, wall 217 is approximately 0.5 mm thick. In certain implementations, wall 217 is approximately 0.6 mm thick.
