Welding lead connector and welding lead connector including locking mechanism

A method of securing a male welding lead connector to a female welding lead connector, the method comprising:

• a. providing a male welding lead connector comprising:
• i. a slide button;
• ii. a core member including a first end and a second end, the core member further comprising:
• 1. an annular space defined in part by an annular channel proximate to the second end of the core member;
• 2. a slot extending at least partially along the core member to the second end of the core member;
• and
• 3. an annular ring along the second end of the core member, the ring including a flat edge including a notch defining a second end of the slot;
• and
• iii. a slidable member engaged in the slot and configured to slide from a first position wherein the annular space is clear to a second position wherein a second end of the slidable member blocks a first portion of the annular space, wherein the first end of the slidable member is connected to the slide button for moving the slidable member to or from the first position or the second position;
• and
• b. providing a female welding lead connector comprising:
• i. a cavity defined by an interior surface of the female welding lead connector, the cavity configured for receiving the second end of the core member;
• and
• ii. a protrusion along the interior surface of the cavity;
• c. inserting the second end of the core member of the male welding lead connector into the cavity of the female welding lead connector a distance sufficient for the protrusion to clear the flat edge of the annular member of the core member such that the protrusion is aligned with a portion of the annular space;
• d. rotating the female welding lead connector relative to the male welding lead connector such that the protrusion of the female welding lead connector enters the annular channel;
• e. moving the slide button such that the slidable member moves from the first position to the second position, thereby blocking the annular channel with the second end of the slidable member and preventing the female welding lead connector from rotating relative to the male welding lead connector, thereby locking the female welding lead connector to the male welding lead connector.

A male welding lead connector comprising:

• a. a core member comprising a first end and a second end wherein the second end is configured for being inserted in and rotated in a female welding lead connector, the core member further comprising:
• i. a slot extending lengthwise at least partially along the core member;
• and
• ii. a protuberance extending radially outward proximate to the second end of the core member;
• b. a slidable member comprising a first end and a second end, the slidable member engaged in the slot and configured to slide from a first position wherein the second end of the slidable member is farther from the second end of the core member to a second position wherein the second end of the slidable member is closer to the second end of the core member;
• c. a slide button;
• d. the slidable member wherein the first end of the slidable member is connected to the slide button for moving the slidable member to or from the first position or the second position, the slidable member further comprising a plurality of teeth aligned in series together along the slidable member;
• and
• e. a multiple-dial combination lock comprising a plurality of rotatable discs configured to rotate around the core member and including alpha-numeric characters along outer surfaces of the discs, wherein the plurality of discs are configured to selectively align with the plurality of teeth of the slidable member based on the rotational positions of the plurality of rotatable discs wherein the slidable member is free to move from the second position to the first position when the plurality of discs are selectively aligned with the plurality of teeth and wherein the plurality of discs prevent the slidable member from moving from the second position to the first position when at least one disc of the plurality of discs is misaligned with the plurality of teeth of the slidable member.

A method of securing a male welding lead connector to a female welding lead connector, the method comprising:

• a. providing a male welding lead connector comprising:
• i. a slide button;
• ii. a male welding lead connector core member including a first end and a second end, the male welding lead connector core member further comprising:
• 1. a male welding lead connector core member slot extending lengthwise at least partially along the male welding lead connector core member;
• and
• 2. a protuberance extending radially outward proximate to the second end of the male welding lead connector core member;
• and
• iii. a slidable member comprising a first end and a second end, the slidable member engaged in the male welding lead connector core member slot and configured to slide from a first position wherein the second end of the slidable member is farther from the second end of the male welding lead connector core member to a second position wherein the second end of the slidable member is closer to the second end of the male welding lead connector core member;
• b. providing a female welding lead connector comprising a female welding lead connector core member, the female welding lead connector core member further comprising:
• i. a cavity extending into the female welding lead connector core member, the cavity configured for receiving the second end of the core member;
• ii. a first longitudinal segment of the female welding lead connector core member further comprising:
• 1. an entrance aperture defining an entrance to the cavity along a first end of the first longitudinal segment;
• and
• 2. a first longitudinal segment slot extending from the first end of the first longitudinal segment to a second end of the longitudinal segment;
• iii. a gap directly adjacent to the first longitudinal segment along a side portion of the female welding lead connector core member wherein the first longitudinal segment slot extends to a juncture where the first longitudinal segment slot meets the gap and wherein the gap extends around the side portion of the female welding lead connector core member beyond the juncture;
• c. inserting the second end of the male welding lead connector core member into the cavity of the female welding lead connector a distance sufficient for the protuberance to move through the first longitudinal segment slot and into the gap;
• d. rotating the female welding lead connector relative to the male welding lead connector such that the protuberance moves along the gap beyond the juncture;
• and
• e. moving the slide button such that the slidable member moves from the first position to the second position causing the second end of the slidable member to enter the first longitudinal segment slot, thereby blocking the female welding lead connector core member from rotating relative to the male welding lead connector core member and thereby locking the female welding lead connector to the male welding lead connector.
