Abstract
An electrical connector comprises a first body rotatably mounted in a hollow second member. In one form, the second member is a hollow cylinder and the first member has a cylindrical portion to fit the cylinder and a tapered portion of snail-cam cross-section to clamp a conductor inserted between the tapered portion and the bore of the second member. Clamping is achieved by relative rotation of the members, a recess for an Allen key being provided in the first member, and projections or serrations are provided to rupture insulation. In a second form, the second member is frusto-conical and the first member is correspondingly tapered. Also described, are an end-cap for the connector with projection-and-recess means to retain it in place, and the use of projections and corresponding recesses for axial location of the members and limitation of the degree of rotation. A double-ended connector is also shown.
