DETAILED DESCRIPTION

[0033] FIGS. 1-9 show various views of an embodiment of a female welding lead connector collar 100. The female welding lead connector collar 100 includes a collar main body 102 and a cover 104 hingedly connected to the collar main body 102. The cover 104 is preferably round and preferably completely covers a first end 106A of the collar main body 102 when the cover 104 is in a closed position as shown, for example, in FIG. 5 and FIG. 7. The collar main body 102 extends from the first end 106A to a second end 106B. The hinge connection between the collar main body 102 and the cover 104 permits the cover 104 to rotate from the closed position to an open position (shown in FIGS. 1-4 and 6) or from the open position to the closed position. When the cover 104 is in the open position and engaged with a female welding lead connector 108, a male welding lead connector can be inserted into a female receptacle 110 of the female welding lead connector 108. When the cover 104 is in the closed position, the cover 104 shields the female receptacle 110, thereby diminishing the chance of an electrical arc or electrocution to a bystander.

[0034] The collar main body 102 is preferably made of nonconductive material (such as, for example, rubber or plastic). The cover 104 is also preferably made of nonconductive material (such as, for example, rubber or plastic).

[0035] The hinge connection between the collar main body 102 and the cover 104 preferably includes a pin 112 which is inserted through a collar main body first aperture 114A, a cover aperture 116, and a collar main body second aperture 114B. The collar main body first aperture 114A is located in a collar main body first appendage 118A and the collar main body second aperture 114B is located in a collar main body second appendage 118B. The cover aperture 116 is located through a cover appendage 122 used to connect the cover 104 to the collar main body 102. The cover appendage 122 is located along a proximal edge 132A of the cover 104. A biasing apparatus 124 is preferably used to either bias the cover 104 in the open position or in the closed position. The biasing apparatus 124 is preferably a torsion spring including an open center 126 through which the pin 112 is inserted. A first leg 128A of the torsion spring is preferably inserted into a collar main body small cavity 130 as shown in FIG. 8, and a second leg 128B of

[0036] Attorney Docket No. 08.03471.0529 the torsion spring is preferably inserted into or proximate to a proximal edge 132A of the cover 104.

[0037] The biasing apparatus 124 preferably includes a first leg 128A and a second leg 128B. FIG. 8 shows an exploded view which include the biasing apparatus 124 and the cover 104.

[0038] An internal surface 134 of the collar main body 102 preferably includes a plurality of collar main body grooves 136 to facilitate tight engagement with an outer surface of a female welding lead connector which often includes bulges such as the female welding lead connector bulges 138 shown in FIGS. 2-7. The collar main body 102 with the plurality of grooves 136 is configured to engage tightly with various models of female welding lead connectors such that it is a universal safety collar for female welding lead connectors. Additionally or alternatively, the internal surface 134 of the collar main body 102 preferably includes collar main body bulges 140 which facilitate tight engagement with an outer surface of a female welding lead connectors which often includes female welding lead connector grooves 142 like those shown in FIGS. 2-7. The collar main body grooves 136 and collar main body bulges 140 are seen more clearly in FIG. 8 which shows an end view of the female welding lead connector collar 100. When used, the collar 100 is preferably slid onto an outer surface of a female welding lead connector. When sliding onto a female welding lead connector, the female welding lead connector bulges 138 are preferably lined up with the plurality of collar main body grooves 136, and the collar main body bulges 140 are lined up with female welding lead connector grooves 142 so that the collar 100 fits tightly onto the female welding lead connector.

[0039] In addition to the collar 100 described above, a kit is disclosed which includes a plurality of collars identical or substantially the same as the collar 100 described above. The kit preferably includes at least three collars (and preferably more) wherein each collar is a different color. By using the kit of different-colored collars, persons using a large number of welding leads on a single project can easily visually distinguish between the different welding leads being used and, thereby, more quickly identify each individual welding lead and the apparatus(es) to which that particular welding lead is electrically tied.

[0040] The previously described embodiments of the present disclosure have many advantages. One advantage is the significant increase in safety created by shielding the female receptacle 110

[0041] Attorney Docket No. 08.03471.0529 of a female welding lead connector using the cover 104 to prevent contact with the female receptacle 110 from outside the cover 104 when the female welding lead connector on which the collar is engaged is not in use. Even if a contemporary female welding lead connector is not in use, it can still have a current of electricity flowing to it, creating an electrocution and electric arcing risk. The collar 100 including the cover 104 as described herein significantly reduces this risk because it blocks access to an internal core of a female welding lead connector on which the collar 100 is engaged. The biasing apparatus 124 is an advantage because it can either be configured to bias the cover 104 in the open position or bias the cover 104 in the closed position. The plurality of main body collar main body grooves 136 and the plurality of collar main body bulges 140 help the collar 100 fit tightly onto various models of female welding lead connectors and accommodate outer surface features of such female welding lead connectors, thereby making the collar 100 a universal collar 100 for female welding lead connectors. The grooves 136 and bulges 140 also prevent the collar 100 from rotating when in use along the outer surface of a welding lead connector on which the collar 100 is attached. Current models of female welding lead connectors can be retrofitted with the collar 100 to provide an extra layer of protection against electrocution and electric arcing.
