ABSTRACT:
A coupler (30) for electrically connecting ends of telephone cords which have been terminated with modular plugs (24--24) includes a first portion (31) made of a dielectric material and having a plurality of compartments (45--45) which extend from end to end and which are formed between partitions (41--41), each of which has a centrally disposed bifurcated stem (46). A contact element (42) in the form of a wire having a linear portion (51) and two retroflexed end portions (52--52) is mounted in each compartment with each retroflexed end portion extending between adjacent furcations of the stems. A second portion (32) made of a dielectric material is joined to the first portion and includes an abutment (71) which extends between the furcations (47--47) of the first portion to stabilize the partitions. The second portion cooperates with the first portion to form a pair of back-to-back externally communicating cavities (60--60). Each cavity is adapted to receive a modular plug such that terminals (54--54) of the plug which is inserted into one of the cavities electrically engage associated retroflexed end portions of aligned contact elements between the partitions.
