Description
APPARATUS FOR ORGANIZING EQUIPMENT CABLES
This invention relates to apparatus for organizing equipment cables, and is particularly concerned with such apparatus for grouping cables associated with individual circuit cards.
In telecommunications equipment and the like, interface circuits are provided on printed circuit cards for connecting cabling to the equipment. As the density of such circuits increases, through component integration and miniaturization, a greater number of interface circuits can be provided on each card. The number of cables that can be connected to an individual card is thereby increased, and becomes limited only by the relative physical sizes of connectors and the card. This may result in cable routing and organization problems.
Typically, cables are grouped and secured using tie straps, a satisfactory solution for static systems. However, with software configurable systems, individual cables or whole sets of cables may need to be relocated.
An object of the present invention is to provide an improved apparatus for organizing equipment cables.
In accordance with the present invention there is provided apparatus for organizing equipment cables, comprising: an elongate panel having a substantially flat face and a flange projecting substantially perpendicular from an edge of the panel and extending along its length, the flange having therein a plurality of elongate slots spaced apart from and aligned with each other along the length of the flange; and a plurality of resilient wire members, each having a substantially U-shaped base receivable in a respective slot of the flange, two substantially parallel arms projecting from the ends of the base, and two fingers projecting from the ends of the arms, said fingers having portions substantially adjacent one another to form a resiliently openable gap for receiving a cable therebetween; said elongate panel including means for engaging the base of each wire member to retain said member within the respective slot.
The present invention will be further understood from the following description with reference to the accompanying drawings, in which:
Fig. 1 illustrates an isometric view of parts of apparatus in accordance with an embodiment of the present invention;
Fig. 2 illustrates an isometric view of details of the apparatus of Fig. l;
Figs. 3, 4, and 5 are respectively plan, elevation, and end views of a resilient wire member of the apparatus of Fig. l; and Fig. 6 is an end view of an alternative form of resilient wire member.
Similar references are used in different figures to denote similar components.
Referring to Fig. 1, there is illustrated parts of apparatus in accordance with an embodiment of the present invention. The apparatus for organizing equipment cables comprises an elongate panel 10 of sheet metal, formed to J-shaped cross-section, a mounting bracket 12 for attaching the panel to the equipment frame and a plurality of resilient wire members 20, retained by the panel 10. The panel 10 includes a substantially flat upright 14, a flange 18 projecting substantially perpendicularly from the upper edge of the upright 14 and a transverse cable channel 16. The transverse cable channel 16 has a substantially horizontal portion 15 projecting substantially perpendicularly from the lower edge of the upright 14 and an up-turned portion 17 projecting substantially perpendicularly from the horizontal portion 15. The flange 18 extends along the length of the panel 10 providing therein a plurality of elongate slots 22, spaced apart from and aligned with each other extend the length of the flange 18. Slots 22 are arranged so that one edge of the slot is approximately flush with the surface of the upright 14.
Slots 22 are sized each to receive the wire member 20. The wire member 20 is retained in the slot by raised tabs 24, 26, and 28 as shown in Fig. 2. Tabs 26 and 28 define a final position of the resilient wire member 20 by being raised sufficiently above the surface of the upright 14 to prevent the wire member 20 from slipping over their ends during use of the wire member 20 to group cables. The tab 24 extends over a portion of the wire member 20 thereby holding it against the upright 14.
Each resilient wire member 20, as shown in Figs. 2-5, includes a U-shaped base 32, two substantially parallel arms 34 and two fingers 36. Fingers 36 form a V-shape with a gap 38 at the bottom. Preferably, the length of members 34 is approximately equal to the depth of the cable channel 16.
The size of the tabs 24, 26 and 28 are dependent upon the thickness of the sheet steel used for the upright 14, the thickness of the wire of the resilient wire member 20 and the limitations imposed by the die used to form the tabs. For an embodiment wherein the upright 14 consists of 1.22 mm (0.048 inch) thick sheet steel and the wire member 20 consists of 2.44 mm (0.096 inch) diameter type 304 stainless steel wire, the tab 24 has approximate dimensions of 6.4 mm (0.25 inch) at its base, 5.1 mm (0.20 inch) for its extension and 5.0 mm (0.196 inch) for the height of its raised portion. Tabs 26 and 28 have a base and an extension of approximately 50 percent and 70 percent, respectively, those of the tab 24.
The mounting bracket 12, formed of sheet steel, comprises an elongate substantially flat surface for attaching and reinforcing the upright portion of panel 10 and substantially perpendicular legs 42 having out-turned mounting flanges 44 providing mounting holes 46.
In operation, the apparatus is fastened to an equipment frame (not shown in Fig. 1) using mounting holes 46 in the mounting bracket 12. Each resilient wire member 20 is inserted into a slot 22 corresponding to an installed interface card position 48 in the associated equipment frame as shown in broken lines in Fig. 1. The lower edge of the wire member 20 is resiliently deflected by and resiliently deflects the tab 26 as it is inserted, snapping ;nto position between tabs 26 and 28. The tab 24 is resiliently deflected by the side of the resilient wire member 20 thereby providing a retaining force substantially perpendicular to the surface of the upright 14. Cables 50 are then routed along the cable channel 16 to the desired position, an example of which is shown in Fig. 1. The cables to be grouped are pushed inwards and downwards between fingers 36 until positioned between arms 34. The resiliency of arms 34 both closes the gap 38 after the cables have passed through and retains the cables in the desired grouping.
Alternative arrangements of the fingers 36 are possible, for example the fingers 36 are shown as overlapping J-shaped fingers in Fig. 6. Further, the fingers 36 could be abutting instead of overlapping and of a number of varied shapes, such as C-shaped and V-shaped, without detracting from the operation of the apparatus.
Numerous modifications, variations and adaptations may be made to the particular embodiments of the invention described above without departing from the scope of the invention, which is defined in the claims.

The present invention will be further understood from the following description with reference to the accompanying drawings, in which:
Fig. 1 illustrates an isometric view of parts of apparatus in accordance with an embodiment of the present invention;
Fig. 2 illustrates an isometric view of details of the apparatus of Fig. l;
Figs. 3, 4, and 5 are respectively plan, elevation, and end views of a resilient wire member of the apparatus of Fig. l; and Fig. 6 is an end view of an alternative form of resilient wire member.
Similar references are used in different figures to denote similar components.
Referring to Fig. 1, there is illustrated parts of apparatus in accordance with an embodiment of the present invention. The apparatus for organizing equipment cables comprises an elongate panel 10 of sheet metal, formed to J-shaped cross-section, a mounting bracket 12 for attaching the panel to the equipment frame and a plurality of resilient wire members 20, retained by the panel 10. The panel 10 includes a substantially flat upright 14, a flange 18 projecting substantially perpendicularly from the upper edge of the upright 14 and a transverse cable channel 16. The transverse cable channel 16 has a substantially horizontal portion 15 projecting substantially perpendicularly from the lower edge of the upright 14 and an up-turned portion 17 projecting substantially perpendicularly from the horizontal portion 15. The flange 18 extends along the length of the panel 10 providing therein a plurality of elongate slots 22, spaced apart from and aligned with each other extend the length of the flange 18. Slots 22 are arranged so that one edge of the slot is approximately flush with the surface of the upright 14.
Slots 22 are sized each to receive the wire member 20. The wire member 20 is retained in the slot by raised tabs 24, 26, and 28 as shown in Fig. 2. Tabs 26 and 28 define a final position of the resilient wire member 20 by being raised sufficiently above the surface of the upright 14 to prevent the wire member 20 from slipping over their ends during use of the wire member 20 to group cables. The tab 24 extends over a portion of the wire member 20 thereby holding it against the upright 14.
Each resilient wire member 20, as shown in Figs. 2-5, includes a U-shaped base 32, two substantially parallel arms 34 and two fingers 36. Fingers 36 form a V-shape with a gap 38 at the bottom. Preferably, the length of members 34 is approximately equal to the depth of the cable channel 16.
The size of the tabs 24, 26 and 28 are dependent upon the thickness of the sheet steel used for the upright 14, the thickness of the wire of the resilient wire member 20 and the limitations imposed by the die used to form the tabs. For an embodiment wherein the upright 14 consists of 1.22 mm (0.048 inch) thick sheet steel and the wire member 20 consists of 2.44 mm (0.096 inch) diameter type 304 stainless steel wire, the tab 24 has approximate dimensions of 6.4 mm (0.25 inch) at its base, 5.1 mm (0.20 inch) for its extension and 5.0 mm (0.196 inch) for the height of its raised portion. Tabs 26 and 28 have a base and an extension of approximately 50 percent and 70 percent, respectively, those of the tab 24.
The mounting bracket 12, formed of sheet steel, comprises an elongate substantially flat surface for attaching and reinforcing the upright portion of panel 10 and substantially perpendicular legs 42 having out-turned mounting flanges 44 providing mounting holes 46.
In operation, the apparatus is fastened to an equipment frame (not shown in Fig. 1) using mounting holes 46 in the mounting bracket 12. Each resilient wire member 20 is inserted into a slot 22 corresponding to an installed interface card position 48 in the associated equipment frame as shown in broken lines in Fig. 1. The lower edge of the wire member 20 is resiliently deflected by and resiliently deflects the tab 26 as it is inserted, snapping ;nto position between tabs 26 and 28. The tab 24 is resiliently deflected by the side of the resilient wire member 20 thereby providing a retaining force substantially perpendicular to the surface of the upright 14. Cables 50 are then routed along the cable channel 16 to the desired position, an example of which is shown in Fig. 1. The cables to be grouped are pushed inwards and downwards between fingers 36 until positioned between arms 34. The resiliency of arms 34 both closes the gap 38 after the cables have passed through and retains the cables in the desired grouping.
Alternative arrangements of the fingers 36 are possible, for example the fingers 36 are shown as overlapping J-shaped fingers in Fig. 6. Further, the fingers 36 could be abutting instead of overlapping and of a number of varied shapes, such as C-shaped and V-shaped, without detracting from the operation of the apparatus.
Numerous modifications, variations and adaptations may be made to the particular embodiments of the invention described above without departing from the scope of the invention, which is defined in the claims.
