Abstract
Abstract An electrical connector having a contact pin carried by a body and selectively movable into contact with a conductor received in a body socket. The pin is provided with a blunt end having a peripheral cutting edge, and with an end-open recess inside the cutting edge, the recess receiving the conductor material displaced by the cutting edge as the pin penetrates the conductor. The pin is threadedly mounted to achieve a tight, intimate contact with the conductor upon pin rotation. A pair of such contact pins engage diametrically opposite sides of the conductor, each pin providing a back-up for the other. The body includes adjacent sections interconnected by clamping means located between a pair of conductor-receiving sockets, the body sections acting as leaf springs urging contact pins against the conductors. When the contact pin pierces the insulation of an insulated conductor, the severed insulation pad is received in the end-open recess to avoid wedging of insulation between the contact areas.
