TECHNICAL FIELD
The subject matter disclosed herein relates generally to cable assemblies, and more particularly, to a multi-piece cassette for use in a cable assembly.
BACKGROUND
FIG. 1 depicts a cable assembly 10 having a cassette 12 on each end of a bundle of cables 16. Each cassette 12 houses a plurality of individual telecommunications connectors 14 (e.g., six telecommunications connectors in each cassette). The plurality of telecommunications connectors 14 are connected by the bundle of cables 16 (e.g., six cables, each cable having eight wires). Pulling a cable assembly 10 of this type through an installation area of walls, conduits, and/or narrow spaces to a telecommunications closet is challenging and limited by the size of the cassette 12.
SUMMARY
A multi-piece cassette including a first portion having a plurality of first ports; a second portion having a plurality of second ports; the first portion including a first joining portion; the second portion including a second joining portion; wherein when the first joining portion and the second joining portion are connected, the first ports of the first portion and second ports of the second portion are aligned on a common, single axis.

DETAILED DESCRIPTION
FIG. 2 is a top view of a multi-piece cassette 100 in an example embodiment. The multi-piece cassette 100 includes a first portion 102 and a second portion 104. Each of the first portion 102 and the second portion 104 includes a tab 106 to secure the multi-piece cassette 100 to an opening in a patch panel. The first portion 102 and the second portion 104 are separable.
FIG. 3 is perspective view of the multi-piece cassette 100 showing the first portion 102 detached from the second portion 104. The top and bottom of the first portion 102 are parallel. The side walls of the first portion 102 are perpendicular to the top and bottom. Second portion 104 is constructed in a similar manner The first portion 102 and the second portion 104 each include a joining structure 103 and 105, respectively, to removably couple the first portion 102 and the second portion 104. Joining structures 103 and 105 are formed on the interior side walls of the first portion 102 and the second portion 104. In one embodiment, the joining structure 103/105 is in the form of a dovetail joint. FIG. 4 is an exploded view of the joining structure 103/105 of FIG. 3. Embodiments may use other joining structures such as pins/holes, biscuit joints, finger joints, mortise/tenon joints, tongue/groove joints, etc. The joining structures 103 and 105 are configured to coact mechanically to removable secure the first portion 102 to the second portion 104.
Also depicted in FIG. 3 is a telecommunications connector 110 received in each port 112 of the first portion 102 and the second portion 104 of the multi-piece cassette 100. Telecommunications connector 110 may be an outlet, adapter, coupler, plug, etc., and may terminate to a variety of types of cable, including copper, optical fiber, coax, etc.
FIG. 5 is a front view of the multi-piece cassette 100. The multi-piece cassette 100 includes openings 120 on a front face thereof to receive a mating telecommunications connector that connects with telecommunications connector 110 in each port 112. When coupled by the joining structures 103/105, the openings 120 and the ports 112 of the first portion 102 and the second portion 104 are aligned on a common, single axis, A.
FIG. 6 is perspective view of the multi-piece cassette 100 rearranged in an example embodiment to facilitate pulling the cable assembly, including the multi-piece cassette 100, through installation areas. As shown in FIG. 6, the first portion 102 and second portion 104 are stacked over each other to minimize the overall length of multi-piece cassette 100 during cable pull. Another set of joining structures may be formed on the top and/or bottom of the first portion 102 and the second portion 104, to hold the first portion 102 and the second portion 104 in the stacked position shown in FIG. 6. The joining structures formed on the top and/or bottom of the first portion 102 and the second portion 104 may include a dovetail joint, pins/holes, biscuit joints, finger joints, mortise/tenon joints, tongue/groove joints, etc.
As shown in FIG. 2, the largest dimension of the multi-piece cassette 100 is L2, when first portion 102 and second portion 104 are joined side by side by the joining structure 103/105. By contrast, in FIG. 6 the largest dimension of the multi-piece cassette 100 is L1, when first portion 102 and second portion 104 are stacked one on top of the other. L1 is less than L2 which facilitates pulling the multi-piece cassette 100 through installation areas.
FIG. 7 is perspective view of the multi-piece cassette 100 mounted in a flat patch panel. FIG. 8 is perspective view of the multi-piece cassette 100 mounted in an angled patch panel. A multi-piece cassette 100 is inserted into panel with a simple push-in action and secured by tabs 106. For removal, the two rear tabs 106 are squeezed while pulling back on multi-piece cassette 100.
The multi-piece cassette 100 may be part of a cable assembly having a multi-piece cassette 100 attached to one or both ends of a cable bundle. When it is necessary to pull the cable assembly through an installation area, the first portion 102 and second portion 104 may be detached from each other and stacked (as shown in FIG. 6) to facilitate pulling the multi-piece cassette 100 through the installation area.
Embodiments described herein relate to a 6-port cassette that may be separated into two, 3-port cassettes. It is understood that the cassette may have more or less than 6 ports and may be divided into more than two portions. Further, the number of ports in each portion need not be equal.
