Description

2350944 WIRE RETAINING STRIP

Technical Field

The present invention relates generally to wkimig blocks Ibr use pfly in the communications industry, and more specifically to a novel wire retaining strip with spaces between adjacent connection modules for cable routing therebetween.

Wire connecting systems of this type described herein are well known and have been commercial.ly available for a number of years as the common 11 0-type connector systems. The 11 07type wiring systems are described in several prior patents, including U.S. Patent Numbers 3,611,264; 3,798,587; 4,118,095 and 5,312,270, all of which are hereby incorporated by reference. The wiring strip described in the above references commonly is characteri2ed by a plurality of locking mechanisms extending from the lower surface of the strip to engage the spaced mounting apertures of a base, and a singular row of longitudinally aligned, consecutive contact receiving apertures or openings.

- The conventional 11 0-type g strip suffers from several disadvantages and problems. The longitudinally aligned contact receiving apertures or openings compr the mwd density of connections that might ultimately be made. Additionally, le die b adjacent contact receiving apertures or openings provides significant distance from the firW twist point of wired pairs to termination to the contacts. This feature has been increasingly important with the advent of Category 6 termination requirements. The higher the transmission speeds the closer the final twist 1 point must be to termination. Furthermore, conventional 11 0-type wiring strips are extremely cumbersome to terminate the wires, since the bulky Category 5 and Category 6 cables must be routed over the outertriost wiring strips in order to be able to reach the innermost wiring stfips for termination. This incmases the height dimension of the assembly. Summary of the Invention

The.wire retaining strip made in accordance with the present invention is depicted in Figures 1-9.

Figure I shows the My assembled environment in which the wire retaining strip of the present invention is used. A rack 10 is provided to which many panels can be moume& On each panel 12, a bow 14 is secured to which the wire retaining strips 16 are attacbed. A jumper trough IS may alm be provided to assist in the proper routing of the cables 20. Tbe individual rwimd P Mires 23 from the cables 20 are positioned in their respective slots in the wiring retaining strip 16 and a connector block (not shown) is attached thereto such that additional cables may be electrically connected to the previously attached cables.

4 The'wire retaining strip 16 of the present invention is shown in more detail in Figures 2 and 9A-E. It is a generally rectangular member having first and second pairs of opposing surfaces 25, 27. On one of the first surfaces 25 are a plurality of discrete electrical connection modules 30 disposed equally spaced along the longitudinal extent of the wire retaining strip. A space 32 is provided between adjacent modules 30. The space 32 is of such a din=ion that a connection cable, subs=tially similar in height to the connection modules 30 when properly oriented, can be placed therein.

Each discrete module 30 includes a p"ky of spaced apart teeth 35 extending normally upward from one of the first surfaces 25. Since the teeth 35 are spaced apart, a plurality of wire retaining slots 37 are defined. The teeth 35 alternate in height to assist in the differentiation of the plurality of wire retafflin8 slots 37 between adjacent teeth 35. As can best be seen in Figure 9C, the teeth 35 have a chann 140 in opposing sides thereoú The channels define a plurality of staggered openings or contact receiving aes or cavities 41. These openings 41 accommodate the contacts of a connector block, discussed below.

On the laterally-facing exierior surfaces of alternating teeth 35 are disposed substantially circular shaped retention aids 42. As can be seen from Figure 91), the aids 42 have angled surfaces. These retention aids 42 engage apernires or recessed portions of the connector blocks to physicalky retain the blocks in contact with the connection modules 30 of the wire retaining wip 16.

77he teeth 35 are A #to With retention ribs 43 that are depicied in Figures 6 and 9E. Such a rib 43 is pro along both sides of each tooth 35. Opposing ribs 43 along each slot 37 in reg or gripping the wire poshioned therebetwem As seen in Figures 3 and 9B-E, the wire retaining strip 16 has a plurality of polarizing features 45 that limit the installation of the wire retaining strip 16 to only one proper and correct orientation. Each polarizing feature 45 comprises a member that extends normally downward from one of the surfaces 25. The plurality of polarizing features 45 interact with slots formed in the base for proper orientation of the strip 16.

in addition to the polarizing features 45, the strip 16 is provided with a plurality of snap-lock devices 49 extending downwardly from surface 25. Each snap-lock device 48 comprises a post 50 extending downwardly from surface 25 and a pair of resilient arms 53 extending upwardly and outwardly from one end of the post 50. These devices 48 interface with apertures formed in the base to adequately secure the wire retaining strip 16 in a wcwe, removable fashion to the base.

One of the advantages of the present invention m be appreciated from Figure 4. Figure 4 depicts a base 14 with a number of wire retaining strips 16 attached thereto. The individual twisted pair wires 23 from the cables 20 are positioned in their respective slots in the wiring retaining strip 16 and a connector block 22 is attached thereto such that additional cables may be electrically connected to the previously attached cables. The present invention enables a significantly increased ease of wiring flexibility with the bulky Category 5 and Category 6 cabling while maintaining the same connector density as conventional 11 0- type devices. In particular, the tc ion density is virtually identical to the single row longitudinally aligned 1 10-type configuration. Also, since the staggered contact receiving apertures we -closc)y Waced than the traditional 110 system spacing, the critical final twist poig to tennhmion distance is kept extremely small.

6 To better understand the manner in which a connector interacts with the wire retaining strip, reference should be made to Figures 5-7. Figure 5 shows a partially assembled device with the wire retaining strip 16 attached to the base 14 while Figure 6 shows an exploded view of each of the elements described as assembled in Figure 5. The snap-lock devices 48 of the wire retaining strip 16 are inserted into and in enmement with apen=s 55 disposed in the base 14. Once the wire retaining strip 16 is physically secured to the base 14, a row of wires 23 may then be inserted inio the individual slots 37 of the module 30 and retained therein. Once the wires 23 have been inserted into the slots 37, a connector block 22 with internally disposed insulation displacement contacts 62 may then be fitted onto the individual connector module 30. As can be seen in Figure 5, the wires 23 are terminated by the lower contacts 62 of the connector block 22. The structure and function of the connector block 22 is similar to those commonly used in 11 0-type connection assemblies.

In addition to showing the interface between a partially cut away wire retaining strip 16 and connector block 22, Figure 7 clearly illustrates the available spaces 32 between the connector modules 30 for routing the bulky cables 20. The presence of the spaces 32 also facilitates the wiring of the base, the positioning of punchdown tools, and the locating of "h cords.

11be height advantage achieved with the present invention is illustrated in Fig= 8. The figure dplets an %W view of a fully assembled wiring block wherein the flml cables 65 have bM attached to the top of the connector blocks 22 and routed between each connection module 30. It is an important advantage of the present invention that the overall height of the assembly does not exceed the hei& of the base ends 67. Even 7 though the cables 65 shown are routed above the label panels 69, these cables 65 may in fact be routed underneath the label panels 65 for additional clearance.

While the particular embodiment ofthe present invention has been shown and described, it will be obvious to those skilled in the art that changes and rnodifications maY be made without departing from the invention and its broader aspects. The manner set forth in the foregoing description and accompanying drawings is offered by way of illuaration only and not as a limitation.
