Abstract

Abstract A modular coupler is used to interconnect two modular plug-ended telephone line cords. The coupler includes a first and a second section, each having a base and side walls extending along a length. The first section includes a center wall extending in a width direction between the side walls. A plurality of slots are oriented in a lengthwise direction across the center wall. The second section includes first and second forming walls extending in a width direction and separated by an aperture of sufficient size to receive therebetween the center wall of the first section. A plurality of slots extend in a lengthwise direction across the first and second forming walls and slope inward toward the aperture. A plurality of wires are positioned within the slots of the first and second forming walls. During assembly, the center wall is moved between the first and second forming walls to bend the wires toward the first section while clamping them within the coupler. Once assembled, the first and second sections snap together and form two back-to-back hollow jacks opening out opposite ends of the coupler, each for receiving a plug or jack on the end of a line to be coupled to another line. The plugs and lines are electrically interconnected by the wires in the coupler.
