Description




BACKGROUND




The disclosures herein relate generally to an identification system and method for cables utilized in electronic installations.




In electronic installations, such as those that includes patch panels, hubs, switching apparatus, racks, or the like, a multitude of cables usually extend from the electronic components in the installation. Due to the high number of cables that often are identical or similar in appearance, the individual cables are hard to identify, locate, or trace. Although stickers, adhesive labels, and the like, have been placed on the cables, they are less than satisfactory since they tend to wear out, lose their adhesive properties, and often fall off the cables.




Accordingly, what is needed is a cable identification system and method according to which identifying indicia can be placed on cables easily and quickly, without the danger of it coming off.




SUMMARY




To this end, according to an embodiment of the disclosure, a cable identification system and method are provided according to which one or more rings, having identifying indicia thereon, extend around the cable, and a cover extends around the ring and has a window formed therein, so that rotation of the ring relative to the cover exposes the identifying indicia.




Significant advantages are achieved with the above embodiment since identifying indicia can be placed on cables easily and quickly, without the danger of it coming off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIG. 1

, the reference numeral


10


refers to a cable which is to be identified in accordance with an embodiment of the present disclosure. To this end, five identical split rings


12


are placed around the cable


10


in a side-by-side relationship. Each ring


12


is preferably manufactured of a firm plastic, such as nylon, and is split to form two slightly-spaced ends


12




a


and


12




b.


This enables the ends


12




a


and


12




b


of each ring


12


to be pulled apart and the ring placed around the cable


10


, after which the ring


12


springs back around the cable under its inherent spring tension, as shown in FIG.


1


. Each ring


12


has alpha-numeric indicia formed on its outer surface and extending around the circumference of the ring. In the example shown, the indicia is in the form of a series of circumferentially-spaced letters and numbers which are used, in a manner to be described, to identify the cable


10


.




A cover cylinder


16


is shown in

FIGS. 2 and 3

and is formed by two split, arcuate portions


16




a


and


16




b.


Each cylinder portion


16




a


and


16




b


is preferably manufactured of either a high impact plastic, such as ABS, or a relatively firm plastic, such as nylon. The junction between the two cylinder portions


16




a


and


16




b


is preferably of a reduced cross-section to form a hinge to permit the portions to be pivoted relative to each other from the opened position shown in

FIGS. 2 and 3

, to the closed position shown in

FIG. 4. A

window


18


is formed in the cylinder portion


16




a


and is sized to selectively expose one of the numerals or letters of each ring


12


in a manner to be described.




As better shown in

FIG. 3

, a pair of spaced retaining wings


20


and


22


are located on the inner surface of the cylinder portion


16




a,


and a pair of spaced retaining wings


24


and


26


are located on the inner surface of the cylinder portion


16




b.


Each wing


20


,


22


,


24


and


26


is arcuate in shape to conform to the inner surfaces of the cylinder portions


16




a


and


16




b,


and is preferably formed by a resilient material, such as rubber. One side wall of each wing


20


,


22


,


24


and


26


extends substantially flush with the corresponding end of the cylinder portions


16




a


and


16




b.


The wings


20


,


22


,


24


, and


26


can be attached to their respective cylinder portions


16




a


and


16




b


in any conventional manner. A pair of spaced internal ribs


30


and


32


are formed on the internal surface of the cylinder portion


16




a,


and a pair of spaced internal ribs


34


and


36


are formed on the internal surface of the cylinder portion


16




b.


The ribs


30


,


32


,


34


, and


36


are spaced from the corresponding ends of the cylinder portions


16




a


and


16




b


to maintain the corresponding wings


20


,


22


,


24


and


26


in the flush positions described above.




As shown in

FIGS. 2 and 3

, an axially-extending groove


36




a


is formed in the distal end portion of the cylinder portion


16




a


to form an adjacent tab


36




b,


and an axially-extending groove


38




a


is formed in the distal end portion of the cylinder portion


16




b


to form an adjacent tab


38




b.


The tabs


36




b


and


38




b


are sized relatively to the grooves


36




a


and


38




a


so that the tabs can be inserted in the respective grooves in a friction fit to permit the cylinder portions


16




a


and


16




b


to be locked in the closed position of

FIG. 4

, as will be described.




After the rings


12


have been installed over the cable


10


in the above manner, and as shown in

FIG. 1

, the cylinder portions


16




a


and


16




b


are placed proximate to the cable and pivoted from their open position shown in

FIGS. 2 and 3

to their closed position shown in

FIG. 4

, in a manner to capture the cable


10


and the rings


12


within the cylinder


16


. The tab


36




b


of the cylinder portion


16




a


is inserted in the groove


38




a


of the cylinder portion


16




b,


and the tab


38




b


of the cylinder portion


16




b


is inserted in the groove


36




a


of the cylinder portion


16




a,


to lock the cylinder portions in their closed position. In this closed position, the wings


20


,


22


,


24


, and


26


engage corresponding portions of the cable


10


, with the thicknesses of the wings being designed relative to the diameter of the cable so that the cable compresses the wings slightly to insure that the wings firmly grip the cable.




The design is such that, after the above installation, the diameter of each ring


12


is equal to, or slightly smaller than, the inner diameter of the cylinder


16


. The above-mentioned spring tension of each ring


12


maintains it in position, yet permits a pin, or the like, to engage each ring and rotate it relative to the cylinder


16


and the cable


10


until the desired alpha-numeric indicia on each ring is exposed by the window


18


. In this manner the cable


10


can be identified with five of alpha-numeric indicia corresponding to the number of rings


12


.




Thus, identifying indicia can be permanently placed on cables easily and quickly, without the danger of the indicia falling off the cable. Also, the identifying indicia can easily be changed and the identifying system of the above embodiment can be easily removed and placed on another cable. Moreover, the resilient wings


20


,


22


,


24


and


26


will accommodate cables of different diameters.




It is understood that variations may be made in the foregoing without departing from the scope of the disclosed embodiment. For example, the number of rings


12


that are utilized can vary. Also, other techniques can be used to permit the relative pivotal movement between the cylinder portions


16




a


and


16




b,


such as, for example, the use of a separate hinge, or the like. Further, the mechanism disclosed above for locking the cylinders can vary. Also, spatial references, such as “inner”, “outer”, “over”, “under”, etc, are for the purpose of illustration only and do not limit the specific orientation or location of the structure described above.




Since other modifications, changes, and substitutions are intended in the foregoing disclosure, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosed embodiment.
