The present invention generally relates to routing twisted conductor pairs of a cable to a jack module and, in particular, to devices, systems and methods for controlling the consistency with which the twisted conductor pairs are routed.
DESCRIPTION OF THE RELATED ARTAs is known, communications patch panels frequently incorporate the use ofjack modules 100, as shown in
Referring now to
Such methods of routing twisted pairs on the back of existing jack modules 100 have proved adequate for existing performance levels. This is because in the past variation of the routing of twisted pairs, from pair to pair, has had little effect if any on performance. However, recent developments, such as patch panels requiring category 6 performance levels, are much more sensitive to variations in twisted pair dress and routing.
Therefore, there is a need for improved devices, systems and methods that address variations in twisted pair dress and routing and/or other shortcomings of the prior art.
SUMMARYBriefly described, the present invention relates to devices, systems and methods for reducing variations in how twisted pairs from a communications cable are routed to jack modules.

The cap includes an upper portion, a bottom portion, a plurality of twisted pair channels extending between the upper portion and the bottom portion, and a pair of opposed end walls, each of the end walls including a plurality of wire constraints disposed thereon. Each wire constraint has opposed surfaces configured to retain one of the conductors and each twisted conductor pair extends through one of the twisted pair channels and the conductors of the twisted conductor pairs are disposed in the plurality of wire constraints such that each conductor is aligned with one of the insulation displacement connectors when the bottom portion is disposed adjacent the jack module.
Another embodiment of the present invention provides a method of routing twisted conductor pairs from a cable onto a jack module including insulation displacement connectors. The method includes the steps of: providing a cap having a top portion and a bottom portion; passing each of the twisted conductor pairs through the cap from the top to the bottom portion; engaging a portion of the cap with each of the conductors such that each conductor is immobilized; and disposing the cap on the jack module such that the bottom portion is adjacent the jack module and each of the conductors electrically engages one of the insulation displacement connectors.
Another embodiment of the present invention provides a jack module system configured to receive a plurality of twisted conductor pairs and at least one communication connector. The system includes a housing having a front portion including a jack opening configured to receive the communication connector and a back portion including a terminal connection region configured to receive the twisted pair conductors. A jack receptacle, a printed wiring board, and a plurality of insulation displacement connectors are disposed within the housing such that the jack receptacle is aligned with the jack opening and the plurality of insulation displacement connectors are accessible through the terminal connection region. The jack receptacle and the plurality of insulation displacement connectors are disposed on opposite sides of the printed wiring board. The system further includes a back-end variation control cap including an upper portion, a bottom portion, a plurality of twisted pair channels extending between the upper and the bottom portions, and a plurality of wire constraints disposed on the bottom portion, wherein each wire constraint is configured to retain one of the conductors. Each twisted conductor pair extends through one of the twisted pair channels and the conductors are disposed in the plurality of wire constraints such that each conductor is aligned with one of the insulation displacement connectors when the bottom portion slidably engages the terminal connection region.

Referring now to
A plurality of punch-down walls 170 also are included. One punch-down wall 170 is provided for each conductor 126 that is to be routed within the back-end variation control cap 140. Preferably, the punch-down walls 170 are disposed in substantially parallel pairs, each pair including a punch-down wall 170 disposed on opposing sides of each twisted pair splitter 160 and extending to an associated wire constraint 156. Preferably, as shown in
As previously noted, the embodiment shown is configured for use with a standard communications cable 120 that includes a cable jacket 122 and four twisted conductor pairs 124, as shown in FIG. 7. For ease of description, the four twisted conductor pairs are designated 124a, 124b, 124c and 124d.
During use, each twisted conductor pair 124a-d is routed through the corresponding twisted pair channel 146a-d, as shown in FIG. 7. The twisted conductor pairs 124a-d are pulled through the twisted pair channels 146a-d until the cable jacket 122 abuts the upper portion 142 of the back-end variation control cap 140. Next, as shown in
For ease of description, reference will now be made only to twisted conductor pair 124a. After the conductors 126a of twisted conductor pair 124a have been separated at the twisted pair splitter 160, each conductor 126a is extended outwardly toward a corresponding wire constraint 156a. The conductors 126a are disposed adjacent the bottom ledge 172 of an associated punch-down wall 170 (FIG. 5B). After the conductors 126a have been routed along the punch-down walls 170, the conductors 126a are frictionally restrained by the wire constraints 156a, thereby maintaining the conductors 126a in the desired routing positions. As well, by frictionally engaging the conductors 126a with the wire constraints 156a, the communications cable 120 is held in place such that the cable jacket 122 remains adjacent the upper portion 142 of the back-end variation control cap 140. By repeating the above steps discussed with regard to twisted conductor pair 124a for twisted conductor pairs 124b-d, the twisted conductor pair routing arrangement as shown in
After the twisted conductor pairs 124a-d have been routed as desired, the back-end variation control cap 140 is positioned above the back portion 110 of the jack module, see, for example, jack module 100 (FIG. 4), such that the twisted conductor pairs 124a-d are aligned with the appropriate terminal slots 118. For the routing configuration shown in
As shown in FIG. 6B and
The foregoing description has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Modifications and/or variations are possible in light of the above teachings. The embodiments discussed, however, were chosen and described to illustrate the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention and various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and/or variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly and legally entitled.
