DETAILED DESCRIPTION

(10) FIGS. 1-7 show various views of an embodiment of a female welding lead connector 100. FIG. 1 shows an exploded view from a first perspective of the female welding lead connector 100 in a disassembled configuration and FIG. 2 shows an exploded view from a second perspective of the female welding lead connector 100 in a disassembled configuration. FIG. 3 shows a perspective view of the fully assembled welding lead connector 100, FIG. 4 shows a cross-sectional side view of the fully assembled welding lead connector 100, and FIG. 5 shows a plan view of the fully assembled welding lead connector.

(11) The female welding lead connector 100 includes a main body 102 including a first end 104A and a second end 104B. A cover 106 is hingedly connected to the main body 102 proximate the first end 104A of the main body 102. The cover 106 is preferably round and preferably completely covers the first end 104A of the main body 102 when the cover 106 is in a closed position as shown, for example, in FIG. 5 and FIG. 7. The hinge connection between the main body 102 and the cover 106 permits the cover 106 to rotate from the closed position to an open position (shown in FIG. 3 and FIG. 4) or from the open position to the closed position. When the cover 106 is in the open position, a male welding lead connector can be inserted into a female receptacle 108 of the female welding lead connector 100. When the cover 106 is in the closed position, the cover 106 shields the female receptacle 108, thereby diminishing the chance of an electrical arc or electrocution to a bystander.

(12) The main body 102 preferably includes an external shell 110 made of nonconductive material (such as, for example, rubber or plastic) and an internal core 112 made of conductive material. The cover 106 is preferably made of nonconductive material (such as, for example, rubber or plastic). The internal core 112 includes the female receptacle 108. A welding lead can be connected to the female welding lead connector 100 through an aperture 113 along the second end 104B of the main body.

(13) The hinge connection between the main body 102 and the cover 106 preferably includes a pin 114 which is inserted through a main body first aperture 116A, a cover aperture 117, and a main body second aperture 116B. The main body first aperture 116A is located in a main body first appendage 118A and the main body second aperture is located in a main body second appendage 118B. The cover aperture 117 is located in a cover appendage 119 used to connect the cover 106 to the main body 102. A biasing apparatus 120 is preferably used to either bias the cover 106 in the open position or in the closed position. The biasing apparatus 120 is preferably a torsion spring including an open center 122 through which the pin 114 is inserted. A first leg 124A of the torsion spring is preferably inserted into a main body small cavity 126 as shown in FIG. 1 and FIG. 4, and a second leg 124B of the torsion spring is preferably inserted into or proximate to a proximal edge 128A of the cover 106.

(14) The cover 106 preferably includes a fastener 130 including a male member 132 extending out orthogonally from a distal edge 128B of the cover 106 and a female member 134 located along a distal edge 136B of the first end 104A of the main body 102. The male member 132 and female member 134 are configured to mechanically engage with one another to secure the cover 106 in the closed position when it is closed. The male member is preferably a two-pronged clip and the female member is preferably a gap along the distal edge 136B of the first end 104A of the main body 102. FIG. 6 shows the cover 106 in an almost closed position right before the male member 132 engages with the female member 134, and FIG. 7 shows the female welding lead connector 100 after the cover 106 has been closed to the closed position wherein the male member 132 is physically engaged with the female member 134. The terms “distal” and “proximal” as used in this context are referring to positions relative to the hinged connection between the cover 106 and the main body 102.

(15) The cover 106 preferably further includes a tab 138 extending out radially from the distal edge 128B of the cover 106. The tab 138 is present to provide traction for a user's finder to open the cover to an open position.

(16) 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 108 using the cover 106 to prevent contact with the female receptacle 108 from outside the cover 106 when the female welding lead connector 100 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 female welding lead connector 100 including the cover 106 as described herein significantly reduces this risk because it blocks access to the internal core 112 of the female welding lead connector. The biasing apparatus 120 is an advantage because it can either be configured to bias the cover 106 in the open position or bias the cover 106 in the closed position. The tab 138 provides a way to more easily open the cover 106 to the open position when engaging the female welding lead connector 100 with a male welding lead connector. The fact that the cover 106 is connected to the main body 102, forming a part of the female welding lead connector 100, is advantageous over using some type of separate plug or other separate device which could easily be misplaced or unavailable because it does not form part of the female welding lead connector. By making the cover 106 a part of the structure of the female welding lead connector 100, the cover 106 is always readily available as a safety feature.

(17) The foregoing description of preferred embodiments of the present disclosure has been presented for purposes of illustration and description. The described preferred embodiments are not intended to be exhaustive or to limit the scope of the disclosure to the precise form(s) disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the disclosure and its practical application, and to thereby enable one of ordinary skill in the art to utilize the concepts revealed in the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the disclosure as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.

(18) Any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specific function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. § 112, ¶6. In particular, the use of “step of” in the claims herein is not intended to invoke the provisions of 35 U.S.C. § 112, ¶6.
