Abstract
A self-shearing connector for electrical conductors comprises a helical spring of rectangular cross-section wire around a central member extending from a body member. The spring has an upper or end turn with an end part of an external diameter smaller than the inner diameter of the next or lower turn. On compression of the spring the end part of the upper or end turn is pushed down into the next turn shearing off the end of the conductor. The conductor is gripped between the lower turn and the body or between the spring turns. If the conductor is insulated, the gripping pressure splits the insulation at opposite sides of the conductor to provide electrical contact.
