Abstract
Abstract A modular telephone jack has a plurality of cantilever spring wire contact members extending down from a top part into an aperture which receives a modular plug. Instead of being positioned in holes extending through the top part, being then bent down and then back, the contact members are molded in at one end into the top part. This avoids bending of the wire, with possible cracking of corrosion preventive plating and also reduces the amount of wire. As an additional feature the jack may be of two parts, slid together and held together at front end by interengaging formations, with one or more resilient members engaged in detents at the rear ends.
