Power connector set

A single-pole electrical connector adapted for carrying high electrical current comprising:

• a conductive receptacle member adapted to be coupled to an electrical cable;
• a conductive plug member adapted to be coupled to an electrical cable;
• said receptacle member incorporating a pin contact portion;
• said pin contact portion including a longitudinally-extending cylindrical rod-like member with a free end, said rod-like member having an external diameter at the free-end, said rod-like member being coaxial with said pin contact portion and having a portion with a diameter smaller than the diameter of said rod-like member at the end opposite said free end;
• said plug member incorporating a cylindrical socket contact portion having an internal diameter;
• said receptacle member and said plug member being adapted for sliding mechanical engagement along a common longitudinal axis;
• said rod-like member having one or more slots formed therein to form at least one pair of resilient finger members by fabricating at least one diametrical slot extending across the external diameter of said rod-like member and through the portion of said rod-like member having a smaller diameter than the diameter of said rod-like member;
• said rod-like member having an external diameter slightly larger than the internal diameter of said socket contact portion prior to having the slots formed therein;
• each of said finger members extending radially outwardly relative to the longitudinal axis of said pin contact portion as a result of the slots contained therein, whereby the external diameter of a pair of opposite finger members is greater relative to said external diameter of said rod-like member before the formation of said slots;
• said finger members being further adapted to be compressed in a radial direction and to engage a corresponding surface of said socket contact member when said receptacle member and said plug member are engaged.
