## Background
FIELD OF THE INVENTION
The present invention relates generally to a routing assembly for wires in electronic assemblies and the like. More specifically, the present invention relates to a rotary wire loom assembly for routing and retaining high power wires in electronic assemblies and the like. This rotary wire loom assembly serves to organize, separate, protect, and isolate the high power wires, allowing them to be packaged very densely.
BACKGROUND OF THE INVENTION
Conventionally, in electronic assemblies and the like, high power wires are simply routed from point A to point B and “zip-tied” to one another and to anchor points along their path. Disadvantageously, this leads to disorganized wires that are not adequately and/or effectively separated from one another (e.g. power supply wires from return wires). This also leads to wires that chaff against one another, as well as against sharp objects. This further leads to high current wires that are inadequately isolated from one another—resulting in interference and heat build up that impacts the efficiency of power delivery, for example. One considerable challenge in dealing with high power and high current wiring is that such wiring is typically heavy and stiff, and, therefore, difficult to manipulate.
Thus, what is needed in the art is an improved routing assembly for wires in electronic assemblies and the like.

DETAILED DESCRIPTION OF THE INVENTION
Again, in various exemplary embodiments, the present invention provides a rotary wire loom assembly for routing and retaining high power wires in electronic assemblies and the like. This rotary wire loom assembly serves to organize, separate, protect, and isolate the high power wires, allowing them to be packaged very densely.
FIG. 1 is a perspective diagram illustrating one exemplary embodiment of a densely packaged power distribution unit (PDU) 10 that is configured to handle eight individual power feeds 12 (the relative positions of which are illustrated in FIG. 1) that must be logically organized as they are routed from the front panel 14 to their respective filter boards 16 (the relative positions of which are illustrated in FIG. 1). It will be readily apparent to those of ordinary skill in the art that the contributions of the present invention may be utilized in conjunction with an electronic assembly other than the PDU 10, with wires or cables other than the power feeds 12, and between components other than the front panel 14 and the filter boards 16, these contributions being flexible and robust.
FIG. 2 is a perspective diagram of one exemplary embodiment of the rotary wire loom assembly 20 of the present invention, highlighting the rotary wire looms 22 and the elongate member 24 that make up the rotary wire loom assembly 20. Each of the rotary wires looms 22 includes an annular structure 26 defining and having a primary inside surface and diameter 28 and a primary outside surface and diameter 30. The primary inside surface and diameter 28 may have any suitable dimension and shape for mating with a corresponding primary outside surface and diameter 32 of the elongate member 24 (substantially octagonal surfaces and diameters are illustrated in FIG. 2). Preferably, the primary outside surface and diameter 30 of the annular structure 26 defines and includes a plurality of channels 34 configured to receive and retain the power feeds 12 or any other wires or cables of interest. Although substantially circular channels 34 are illustrated in FIG. 2, it will be readily apparent to those of ordinary skill in the art that other cross-sectional shapes may be utilized. Preferably, the primary diameter of each of the channels 34 is slightly smaller than the primary diameter of the insulation of each of the power feeds 12 or other wires or cables of interest so that each of the power feeds 12 or other wires or cables of interest is securely retained in the corresponding channel 34 of the annular structure 26. The annular structures 26 may be made of a metal, an impact resistant plastic, a ceramic, or any other suitable material. The elongate member 24 is slid through the primary inside surface and diameter 28 of each of the annular structures 26, and the relative position of each of the annular structures is selected and fixed using a screw 36, bushing (not illustrated in FIG. 2), and/or the like. Preferably, the retention member utilized does not interfere with the desired routing of any wire or cable. The elongate member 24 may also be made of a metal, an impact resistant plastic, a ceramic, or any other suitable material.
FIG. 3 is a perspective diagram illustrating one exemplary embodiment of the rotary wire loom assembly 20 of FIG. 2 packaged in the PDU 10 of FIG. 1. In general, the rotary wire loom assembly 20 is disposed within the PDU 10 or other electronic assembly or the like and oriented in a direction that is conducive to routing wires or cables as desired. In the exemplary embodiment illustrated, the rotary wire loom assembly 20 spans the PDU 10 from side to side, and is anchored at each side via a raised receiving platform 40 and one or more retention screws 42 that are disposed through the housing 44 of the PDU 10 and into the elongate member 24 of the rotary wire loom assembly 20. It will be readily apparent to those of ordinary skill in the art that other retention mechanisms may also be used to hold the rotary wire loom assembly 20 in a given electronic assembly or the like, provided again that the desired routing of the wires or cables is not interfered with.
FIG. 4 is a perspective diagram illustrating one exemplary embodiment of the load side power feeds 12, 50 routed from the breakers 52 through the rotary wire loom assembly 20 of FIG. 2, with the elongate member 24 of FIG. 2 supporting the weight of the wiring. Preferably, each wire 12, 50 is routed from the corresponding breaker 52 and into/through a channel 34 (FIG. 2) of the adjacent annular structure 26 (FIG. 2) of the rotary wire loom assembly 20. The wire 12, 50 is then routed into/through the corresponding channel 34 of each of the annular structures 26 adjacent to the first annular structure 26 to one side or the other, thereby being threaded through and retained by the rotary wire loom assembly 20 until it exits to a termination point of interest directly or indirectly adjacent one end of the rotary wire loom assembly 20. The same is true for each of the wires 12, 50.
FIG. 5 is a perspective diagram illustrating one exemplary embodiment of the return side power feeds 12, 60 routed from the terminal blocks 62 through a second rotary wire loom assembly 20 of FIG. 2, with the elongate member 24 of FIG. 2 again supporting the weight of the wiring. Preferably, each wire 12, 60 is routed from the corresponding terminal block 62 and into/through a channel 34 (FIG. 2) of the adjacent annular structure 26 (FIG. 2) of the rotary wire loom assembly 20. The wire 12, 60 is then routed into/through the corresponding channel 34 of each of the annular structures 26 adjacent to the first annular structure 26 to one side or the other, thereby being threaded through and retained by the rotary wire loom assembly 20 until it exits to a termination point of interest directly or indirectly adjacent one end of the rotary wire loom assembly 20. The same is true for each of the wires 12, 60. Again, in the exemplary embodiment illustrated, the rotary wire loom assembly 20 spans the PDU 10 from side to side, and is anchored at each side via a raised receiving platform 40 and one or more retention screws 42 that are disposed through the housing 44 of the PDU 10 and into the elongate member 24 of the rotary wire loom assembly 20. Again, it will be readily apparent to those of ordinary skill in the art that other retention mechanisms may also be used to hold the rotary wire loom assembly 20 in a given electronic assembly or the like, provided again that the desired routing of the wires or cables is not interfered with.
Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results. For example, the rotary wire loom assembly for routing and retaining high power wires in electronic assemblies and the like of the present invention may take the form of a variety of assemblies for organizing, separating, protecting, and isolating wires, may be utilized in conjunction with a variety of wires or cables, and may be utilized in a variety of applications, not necessarily limited to high power wires in electronic assemblies as illustrated and described.
