ELECTRICAL CONTACT ABSTRACT OF THE DISCLOSURE An electrical contact (100) for terminating an elec- trical conductor including an inner sleeve member (10) stamped from a flat sheet of conducting material and formed in a cylindrical shape, with its rear portion (16) including a plurality of round holes (19) extending through the sleeve member and internal circumferential grooves. The round holes are arranged in radially spaced portions, each including a closely-adjacent pair of axially spaced holes (19a, 19b) and a third hole (19c) spaced axially from the pair of holes. The internal grooves or grooved indentations (18) extend circum- ferentially around the inside periphery of the formed cylindrical contact sleeve. The grooved indentations are located in the rear conductor-receiving portion (16) of the sleeve, preferably forwardly of the rear-most holes (19c). A conductor, inserted into the rear end of the formed sleeve member at least as far forward as the is crimped into tight contact within the sleeve by a crimping apparatus having a plurality of radially spaced bi-lobed crimping members positioned for crimping the sleeve member in the region of the holes and grooves. The bi-lobed crimping members are positioned to have one lobe in the region of the pair of holes (19a, 19b), the other in the region of the third hole (19c). One of the crimper lobes is also preferably in the region of the grooved indentations (18). The finished contact pre- ferably includes a second (liner) sleeve (30) surrounding the crimped sleeve and a forward hood 140) mounted to the contact to form a three piece contact assembly (100).
