Abstract
Abstract The invention is to a connector for connecting end-to-end line cords of telephone sets, to provide for joining standard lengths of line cord to give increased mobility to telephone sets where miniature plugs and jacks are used. The connector is double ended, having a central body member with conductors extending longitudinally in grooves in a lower surface, the conductors bending up and over the top surface, the conductor ends extending inwards towards each other. A top member fits over the top of the central member and has comb-like members for aligning the ends of the conductors. A cover fits over the bottom of the central member, and at each end of the connector is an aperture profiled to accept a miniature plug, the contacts on the plug contacting ends of the conductors.
