DETAILED DESCRIPTION

(16) Various embodiments will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the appended claims.

(17) A telecommunications connector 10 for connection with a plurality of wires 6 from a cable 4 is shown. In one example, the cable 4 includes a plurality of insulated copper wires 6 while the connectors 10 are modular or RJ-type connectors. As shown, the telecommunications connector has a connector part 12 which includes a jack cavity 14 for receiving a corresponding plug (not shown). In one aspect the connector part 12 includes a plurality of electrical contact members 16 for which electrical connection to the wires 6 will be made through the below described termination process. The connector part 12 is further provided with a pair of cutting edges 18 which are designed to cut the wires 6 of the cable 4 during the termination process.

(18) The connector 10 is also provided with a cable manager part 20 having a main body 22 and an initially attached separable lacing fixture 24. The connector part 12 and the cable manager part 20 used in the various embodiments may be configured in a complementary manner, so that the connector part 12 is able to engage with the cable manager part 20 only in one orientation. As shown, the main body 22 is provided with a central aperture 26 through which the cable 4 and associated wires 6 extend. Referring to FIG. 3, the cable 4 has been stripped to expose eight insulated copper wires 6 and has been inserted through the central aperture 26 of the main body 22.

(19) The main body 22 also includes a plurality of channels 28, each of which is configured to receive and retain an individual wire 6 of the cable 4. As shown, eight channels 28 are provided so as to accommodate a cable having eight wires 6. Aligned with the channels 28 of the main body are an equal number of lacing fixture channels 30 are also configured to receive and retain an individual wire 6. Accordingly, each wire 6 is received and retained by both a channel 28 and a channel 30. As shown at FIG. 4, the wires 6 have been oriented from the position shown in FIG. 3 to a position in which each wire 6 is held within corresponding channels 28 and 30.

(20) As shown, the separable lacing fixture 24 is attached to the main body 22 via a plurality of breakaway portions 32 which extend one each side of the channels 30. The breakaway portions 32 are aligned such that the cutting edges 18 of the connector part 12 are aligned when the connector part 12 is attached to the cable manager part 20. Thus, when the connector part 12 is fully installed onto the cable manager part 20, the cutting edges 18 not only cut the wires 6, but also cut or break the breakaway portions 32, thereby separating the separable lacing fixture 24 from the main body 22. FIG. 5 shows the connector part 12 being initially aligned with the cable manager part 20 such that the cutting edges 18 and the breakaway portions 32 are aligned with each other. FIG. 6 shows the connector part 12 inserted onto the cable manager part 20, but not up to the point where the cutting edges 18 will sever the breakaway portions 32.

(21) In one aspect, the separable lacing fixture 24 includes a first portion 24a and a mirror image second portion 24b, wherein each of the portions 24a, 24b has an equal number of channels 30 and breakaway portions 32. As shown, each portion 24a, 24b has four channels 30 and five aligned breakaway portions 32. The separable lacing fixture 24 may also be provided with a bridge portion 34 extending between the first and second portions 24a, 24b. The separable lacing fixture 24 may be provided with one bridge portion, two bridge portions, or no bridge portions. The bridge portion 34 allows the separable lacing fixture 24 to remain intact as a single component after the separable lacing fixture 24 has been separated from the main body 22.

Wire Termination

(22) A termination tool 7 is frequently used for the purpose of terminating the wires 6 to form the fully assembled connector 2. Such a tool 7 is shown at FIG. 7. Termination tools 7 are known and described in US Patent Application Publication 2011/0304343 A1 and in European Patent EP 1 484 824 B1, the entireties of which are herein incorporated by reference. As shown, the termination tool 7 may be provided with a handle portion 8 and a base portion 9. The force used by squeezing the handle 8 to the tool body 9 is generally normal to the cable axis which is to be terminated.

(23) Once the connector part 12 has been initially inserted onto the cable manager part 20, as shown at FIG. 6, the cable manager part 20 and the connector part 12 are then placed in the tool 7, with the tool 7 being in a retracted position. The handle 8 of the tool 7 is then squeezed so that a pusher element 9a moves laterally into an extended position and thereby forces the connector part 12 fully into engagement with the cable manager part 20. The body 9 of the termination tool 7 provides the necessary opposing force for the terminal insertion within the connector part 12. As this occurs, each wire 6 is additionally pushed further towards an appropriate slot in one of a plurality insulation displacement contacts in the connector part 12. The operation of the wire termination tool 7 from the retracted position to the extended position is shown sequentially shown from FIG. 8 through FIG. 10, wherein the tool 7 is in the fully retracted position in FIG. 8, is in an intermediate position in FIG. 9, and is in the fully extended position in FIG. 10.

(24) As the tool 7 is advanced towards the fully extended position, the cutting edges 18 of the connector part 12 also advance towards the breakaway portions 32 and the wires 6 and eventually cut entirely through the breakaway portions 32 and the wires 6. As a result, severed wires 6a are formed which are retained onto the separated lacing fixture 24. As can be seen at FIG. 11, the tool 7 has been moved back to the fully retracted position and the terminated cable 2, having a fully connected connector part 12 and cable manager part 20 to form the connector 10, has been removed from the tool 7.

(25) In addition to holding the portions 24a, 24b together, the bridge portion 34 of the separable lacing fixture also prevents the separable lacing fixture 24 from being removed from the tool 7 until the terminated cable 2 has also been removed from the tool 7, as shown at FIG. 11. This function is accomplished by virtue of the bridge portion 34 being sandwiched between the tool base portion 9 and the base portion 22 and/or connector part 12 of the connector 10. FIG. 12 shows the separable lacing fixture 24 after being fully removed from the tool 7, at which point the separable lacing fixture 24 and attached wires 6a can be discarded.

(26) Typically, the termination process occurs in the field where the cables 4 are being installed. In such instances, it is common that the excess wires 6a created by the termination process are allowed to fall to the floor and must be collected afterwards. When many termination processes are conducted in the same area, a significant number of excess wires 6a can accumulate which can be problematic. As such, the above described connector 10 having the separable lacing fixture 24 allows for the excess wires 6a to be retained together, whereby the installer can simply discard a single item from the tool 7 with each termination operation.

(27) In one embodiment, the cable manager part 20 can be formed from a polymeric material as a single component, for example, an injection molded plastic component having the separable lacing fixture 24, the main body 22, the bridge portion 34, and the breakaway portions 32. In one example, the base part 22 and the separable lacing fixture 24 are formed together with the breakaway portions 32 being formed as an area of reduced thickness or weakness. Other suitable materials may be used as well, for example a plastic compound filled with metal particles.

(28) The various embodiments described above are provided by way of illustration only and should not be construed to limit the claims attached hereto. Those skilled in the art will readily recognize various modifications and changes that may be made without following the example embodiments and applications illustrated and described herein, and without departing from the true spirit and scope of the disclosure.
