The male connector element is having a first and a second portion configured by longitudinally bi-furcating the male connector element and includes a chamfered portion, a radially adjusting mechanism and a screw. The chamfered portion is axially configured on male connector element and receives the radially adjusting mechanism that moves the first and second portions relative to each other. The screw axially passes through male connector element and radially moves the radially adjusting mechanism to adjust the gap between the first and second portions to adjust external dimension of male connector element. The female connector element is having a tubular configuration that receives male connector element and is having a plurality of longitudinal slits configured thereon, walls of the female connector element are urged radially inwards towards the male connector element to maintain contact there-between by a spring element. ## Claims ### Claim 1 A connector assembly comprising: a male connector sub-assembly comprising: a conductive male pin contact having a first and a second portion configured by longitudinally bifurcating said conductive male pin contact, said conductive male pin contact comprising: a chamfered portion axially configured on said conductive male pin contact; a radially adjusting mechanism received within said chamfered portion and adapted to move said first and second portions of said conductive male pin contact relative to each other; and an adjustment screw axially passing through said conductive male pin contact and adapted to interact with and radially move said radially adjusting mechanism to adjust the gap between said first and second portions to adjust the conductive male pin contact's external diameter; and an insulated cover body assembled over said conductive male pin contact; a female connector sub-assembly comprising: a conductive female sleeve contact having a tubular configuration adapted to receive said conductive male pin contact, said conductive female sleeve contact further having a plurality of longitudinal slits configured thereon, wherein walls of said conductive female sleeve contact are adapted to be urged radially inwards towards said conductive male pin contact received therein to maintain contact there-between by a spring element circumscribing said conductive female sleeve contact; and an insulated cover body assembled on said conductive female sleeve contact. ### Claim 2 (depends on 1) The connector assembly as claimed in claim 1, wherein either of said conductive male pin contact and conductive female sleeve contact of the respective male and female connector assemblies are self-adjustable for facilitating adjusting of respective external and internal diameters thereof. ### Claim 3 (depends on 1) The connector assembly as claimed in claim 1, wherein both of said conductive male pin contact and conductive female sleeve contact of the respective male and female connector assemblies are self-adjustable for facilitating adjusting of respective external and internal diameters thereof. ### Claim 4 (depends on 1) The connector assembly as claimed in claim 1, wherein said first portion and said second portion are identical as said first and second portions are configured by longitudinally bifurcating said conductive male pin contact along a plane passing through center of said conductive male pin contact. ### Claim 5 (depends on 1) The connector assembly as claimed in claim 1, wherein said first and said second portion are non-identical as said first and second portions are configured by longitudinally bifurcating said conductive male pin contact along a plane passing offset from said center of said conductive male pin contact. ### Claim 6 (depends on 1) The connector assembly as claimed in claim 1, wherein said radially adjusting mechanism is a Belleville washer sub-assembly comprising: an operative bottom Belleville washer adapted to rest on said chamfered portion and functionally coupled to said first and second portions of said conductive male pin contact; and an operative top Belleville washer spaced from said operative bottom Belleville washer and adapted to be moved relative to said operative bottom Belleville washer by said adjustment screw to cause radial movement of said operative bottom Belleville washer for facilitating adjusting of the gap between said first and second portions of said conductive male pin contact, thereby adjusting conductive male pin contact's external diameter. ### Claim 7 (depends on 1) The connector assembly as claimed in claim 1, wherein said radially adjusting mechanism is a conical spring sub-assembly comprising: a conical spring element adapted to rest inside a conical cavity configured on an operative top end of the conductive male pin contact and functionally coupled to said first and second portions of said male connector element; and a washer disposed over said conical spring element and adapted to be moved relative to said conical spring element by said adjustment screw to cause radial movement of said conical spring element for facilitating adjusting of gap between said first and second portions of said conductive male pin contact, thereby adjusting conductive male pin contact's external diameter. ### Claim 8 (depends on 1) The connector assembly as claimed in claim 1, further comprising a safety cap secured to an end portion of said conductive male pin contact for providing selective access to said adjustment screw for permitting factory adjustment of said conductive male pin contact only. ### Claim 9 (depends on 1) The connector assembly as claimed in claim 1, wherein said adjustment screw engages with a threaded hole that is axially extending through the conductive male pin contact. ### Claim 10 (depends on 1) The connector assembly as claimed in claim 1, wherein said conductive male pin contact and said conductive female sleeve contact are shrouded by insulated cover bodies.
