Definitions

  • the present invention relates generally to electrical connectors, and more particularly, to a modular communication jack design with an improved wire containment cap.
  • a second problem that exists when terminating wire pairs to the IDC terminals of a jack is variability.
  • a technician is typically called on to properly terminate the wire pairs of a twisted pair cable to the proper IDC terminals of the jack.
  • Each jack terminated by the technician should have similar crosstalk performance. This requires the termination to remain consistent from jack to jack.
  • different installers may use slightly different techniques to separate out the wire pairs and route them to their proper IDC terminals.
  • a solution that controls the variability of terminations from jack to jack would be desirable.
  • a final issue that arises when terminating wire pairs to the IDC terminals of a jack is the difficulty of the termination process.
  • Typical jacks provide little assistance to the technician, resulting in occasional misterminations (e.g. a wire being terminated at an incorrect location in the jack).
  • Even if detailed instructions are provided with the jack technicians may not read these instructions prior to installing the jacks.
  • a jack with a difficult termination process can increase the installation time for the technician and result in a costly installation for the customer.
  • a jack solution that simplifies the termination process and minimizes the possibility of technician error would be desirable.
  • the present application meets the shortcomings of the prior art by providing a wire containment cap having a first side including a plurality of retainers for retaining wires, a second side being opposite the first side, two sidewalls extending between the first side and the second side, and wire pair holes or slots between the first side and the second side.
  • the communication jack comprises a front portion including a retention clip, and a wire containment cap including a retention recess for securing the wire containment cap to the front portion.
  • the wire containment cap comprises a first side including a plurality of retainers for retaining wires, a second side being opposite the first side, two sidewalls extending between the first side and the second side, and wire pair holes or slots between the first side and the second side.
  • Wire containment caps and communication jack assemblies according to the present invention may be provided in shielded or unshielded embodiments. Further, the second side of wire containment caps according to the present invention may be provided with a slot and other features allowing for the use of an integral strain relief clip.

  • the front portion 102 may include such components as plug interface contacts, a mechanism for coupling the jack to a plug, crosstalk compensation circuitry, and wire-displacement contacts to provide an electrical connection between the jack and a communication cable. Additional details on the wire containment cap 104 are described with reference to Figs. 3-11, below.
  • Fig. 2 is a front upper right partial-exploded view of the communication jack 100 of Fig. 1.
  • the wire containment cap 104 is slidably mounted within the front portion 102.
  • a retention clip 106 on the front portion 102 and a retention recess 108 on the wire containment cap 104 may be included to secure the wire containment cap 104 to the front portion 102.
  • a retention latch 110 is also provided in the embodiment of Fig. 2. Other mounting and securing techniques may also be used.
  • Figs. 3-11 illustrate the wire containment cap 104 in further detail.
  • the wire containment cap 104 includes a large opening 112 in the back to allow a cable to be inserted, and allow the pairs to separate in a short distance as they transition toward IDC terminals.
  • the back of the wire containment cap 104 also has a strain relief guide slot 114 and strain relief latch teeth 116 to accommodate a strain relief clip as shown and described in U.S. provisional patent application serial number 60/636,972, filed on December 17, 2004 and entitled "Wire Containment Cap with an Integral Strain Relief Clip.” Shoulders 117 are provided on the left and right along the rear of the wire containment cap 104.
  • the opening 112 provides easy access to two slots 118 having funnel-shaped slot entrances 120.
  • a rear spine 122 separates the slots toward the rear of the wire containment cap 104 and a front spine 124-as shown in Fig. 3-separates wire pairs at the front of the wire containment cap 104.
  • a saddle area 126 serves as a lower support for a cable when the cable is clipped by the strain relief clip.
  • wires are separated and crossed-over as necessary toward the rear of the wire containment cap 104, before the wires are inserted into the slots 118.
  • the saddle area 126 is sufficiently low and the rear spine 122 is sufficiently offset from the rear end of the wire containment cap 104 to provide an installer with ample room to separate and cross-over or "flip" wire pairs as necessary on the rear sides of the slots 118.
  • One reason this flip may be necessary is because the wire pair layout on one end of a twisted pair cable is a mirror image of the wire pair layout on the opposite end of the twisted pair cable. Another reason this flip may occur is because the Telecommunications Industry Association (“TIA”) standards allow structured cabling systems to be wired using two different wiring schemes. Finally, a flip may occur because not all cables have the same pair layout.

  • the technician need only place wire pairs through appropriate slots 118, secure individual wire pairs in the upper and lower wire restraints 128 and 130-as shown in Fig. 3-and attach the wire containment cap 104 to the front portion 102 of the communication jack 100.
  • the slots 118 are preferably sized so that lateral or vertical shifting of wires after the wires have been inserted into the slots 118 is reduced or eliminated.
  • the wire containment cap 104 is constructed of a plastic material, such as a thermoplastic. Alternative materials, shapes, and subcomponents could be utilized instead of what is illustrated in Figs. 3-11.
  • the shoulders 117 serve as support and stopping mechanisms to place the wire containment cap 104 in a correct physical position with respect to the front portion 102 shown in Figs. 1 and 2.
  • Alternative support and/or stopping mechanisms could also be used, such as one located on the front portion 102, or on the wire containment cap 104 in such a position that it abuts an interior location in the front portion 102, rather than the exterior abutment shown in Figs. 1 and 2.
  • Fig. 5 is a rear view of the wire containment cap 104 showing the slots 118 and the funnel-shaped slot entrances 120.
  • Fig. 6 is a right-side view of the wire containment cap 104.

  • a shielded wire containment cap 204 according to one embodiment of the present invention is shown.
  • a rear portion 205 of the shielded wire containment cap 204 is constructed of metal.
  • the metal portion comprises the rear portion of the strain relief guide slot 214, the strain relief latch teeth 216, and the saddle area 226.
  • a front portion 207 of the shielded wire containment cap 204 is preferably constructed of plastic.
  • the slots 218 and the slot entrances 220 of the shielded wire containment cap 204 are larger than the slots 118 of the wire containment cap 104 to accommodate wires with larger diameters.

  • the region around the opening 212 in the rear of the shielded wire containment cap 204 and the setback of the rear spine 222 provides ample room for crossing-over of wires before the wires are inserted by an installer into the slots 218.
  • FIG. 14-20 Additional details of the shielded wire containment cap 204 are shown in Figs. 14-20, similarly to the illustrations of the wire containment cap 104 in Figs. 5-11, above. Elements of the shielded wire containment cap 204-and of other wire containment caps, below-are numbered similarly to similar elements of the wire containment cap 104.
  • Figs. 21-29 show a wire containment cap 304 with four closely-spaced wire-pair holes 309 for accepting wire pairs.
  • Hole entrances 311 (shown in Fig. 22) are offset from a rear end of the wire containment cap 304 to provide room for an installer to cross-over necessary wire pairs before inserting the wire pairs into the hole entrances 311.
  • the hole entrances 311 are preferably provided with funnel-shaped entrance surfaces. According to one embodiment, the holes 309 are sized to accept twisted pairs with conductor diameters of approximately 0.040 inches.
