DETAILED DESCRIPTION

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.

A telecommunications connector assembly 10 is disclosed for connection with a cable 4 having a sheath 5 and a plurality of wires 6 is shown. In some examples, the sheath 5 can be formed from a metal braid, mesh, or foil. In one example, the cable 4 includes a plurality of insulated copper wires 6 while the connector assembly includes a main body 12 configured as a modular or RJ-type connector. As shown, the telecommunications connector main body 12 includes a jack cavity 14 for receiving a corresponding plug (not shown). In one aspect the main body 12 includes a plurality of electrical contact members 16 for which electrical connection to the wires 6 is made. In one aspect, the connector assembly 10 can include a cable management part 20 connected to the main body 12 for receiving and retaining the wires 6 from the cable 4 such that the wires 6 can be properly terminated to the connector assembly 10. The main body 12 can also be provided with a retention structure 18 having members 18a and 18b, opposite the latch member 30, to further secure the connector assembly 10 within the opening 102.

In one aspect, the telecommunications connector assembly 10 includes a latch member 30 that can be removably attached to the main body 12. The latch member 30 is for securing the connector assembly 10 within an opening 102 of a connector panel 100. In one example, the latch member 30 is a unitary structure formed from a metal material, such as steel. A plastic material may also be used, although metal is preferred due to more suitable strength and flexibility properties, and because metal allows the latch member 30 to be made from a relatively thin material. Where metal is used, the latch member 30 can also serve to provide a grounding pathway.

As most easily seen at FIGS. 1 and 3, the latch member 30 can be provided with a first portion 32 and a second portion 34 that are joined by a third portion 36. As presented, the third portion 36 is curved or represents a bent portion of the latch member 30 such that the third portion 36 enables the latch member to perform a spring function. As shown, the third portion 36 holds the first portion 32 at an non-zero angle with respect to the second portion 34.

In one aspect, the first portion 32 includes a pair of locking rib structures 38, wherein each of the locking ribs includes a first rib 38a and a spaced apart second rib 38b. The locking rib structures 38 are for engaging with the connector panel 100 adjacent the opening 102. Once installed, the first ribs 38a engage a front side 100a of the connector panel 100 while the second ribs 38b engage a back side 100b of the connector panel 100 such that the connector assembly 10 is locked in place into the opening 102.

In another aspect, the second portion 34 includes a retention structure 40. The retention structure 40 is for providing a secure connection between the latch member 30 and the main body 12 of the connector assembly 10. As shown, the retention structure 40 includes a pair of tabs 42. The tabs 42 are disposed at an angle relative to remainder of the retention structure 40, thereby creating a height difference between the tabs 42 and the remainder of the retention structure 40. With reference to FIG. 1, it can be seen that the main body 12 is provided with a pair of slot structures 19 which are configured for receiving the side edges 40a, 40b of the retention structure up to the tabs 42. To facilitate installation of the latch member 30 onto the main body 12, the retention structure 40 also includes a ramped section 44 to offset the retention structure from the remaining portion of the second portion 34. This offset allows the latch member 30 to be installed such that at least part of the second portion 34 can be adjacent to the main body 12, as shown in FIG. 2.

Referring to FIG. 1, it can be seen that the latch member 30 is aligned with the main body 12 such that the side edges 40a, 40b of the retention structure 40 can slide into the respective slot structures 19. As the side edges 40a, 40b enter the slot structures 19 and the latch member 30 is pushed in a direction towards the cable manager part 20, the tabs 42 will eventually elastically deform over the top edge 12a of the main body 12 and snap down into cavities 17 located in the main body 12. Once the tabs 42 are within the cavities 17, the latch member 30 is secured to the connector main body 12 such that the latch member 30 cannot be displaced in a direction towards the cavity 14. Other approaches for attaching the latch member 30 to the main body 12 may also be used without departing from the concepts disclosed herein, for example, fasteners, adhesives, differently configured tabs, barbs, and other methods and structures may be utilized.

Referring to FIG. 6, it can be seen that the connector assembly 10 can be installed from a back side 100b of a connection panel 100 and into an opening 102. FIG. 7 shows that the connector assembly 10 can also be installed from a front side 100a of the connection panel 100 into the opening 102. This feature of being able to insert the connector assembly 10 into the opening 102 from either side of the plate 100 is an improvement over prior art connectors that can only be inserted from one direction.

As can be seen at FIG. 8, the connector assembly 10 has been fully installed into the opening 102 (from either direction) such that the ribs 38a and retention member 18a are secured against the first side 100a of the plate 100 and such that ribs 38b and retention member 18b are secured against the second side 100b of the plate 100. In order to move the connector assembly 10 from either of the positions shown in FIG. 6 or 7, a user simply depresses the free end 32a of the first portion 32 of the latch member 30 towards the main body 12 until enough clearance exists to insert tabs 38a or 38b (depending on direction of insertion) through the opening 102. Once this position has been reached, the user can release the first portion 32 and the spring action caused by the third portion 36 will urge the main body 12 towards the top of the opening 102. At this point, the connector assembly 10 is secured to the plate 100.

A primary benefit of the disclosed structure having a spring-type latch member 30 and a low profile main body 12 is that the same connector assembly 10 can be installed in panel openings of various different sizes. For example, in the embodiment shown at FIG. 8, a remaining height H1 exists between the main body 12 and the bottom of the opening 102 that can be accommodated by the latch. Referring to FIGS. 9 and 10, the same connector assembly 10 is shown as being connected to a different plate 200 having an opening 202 that is smaller than opening 102, resulting in a remaining height H2 that is less than height H1. Referring to FIGS. 11 and 12, the same connector assembly 10 is shown as being connected to yet another plate 300 having an opening 302 that is larger than opening 102, resulting in a remaining height H3 that is more than height H1. In one example, connector assembly 10 can be mounted into plates having opening heights of 19.3 millimeters (mm), 20.07 mm, and 20.6 mm, all of which are standard sized telecommunication openings that typically each require differently configured connectors.

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.
