DEVICES FOR MAKING ELECTRICAL CONNECTIONS

摘要

Identical miniature plugs are attached to both ends of a telephone cord. The plugs are mated with miniature jacks in the handset and in the base of a telephone. A plurality of stand-up, blade terminals are positioned in spaced troughs of a housing of the plug with each of the terminals having tangs that pierce the insulation of insulated tinsel conductors of the cord placed in the troughs and pressed into engagement with the tangs by associated ribs formed in a lid of the housing which is welded ultrasonically to the housing. The mating jack has a plurality of U-shaped stand-up, blade terminals with provisions similar to the plug for making electrical contact with conductors leading into the jack. One leg of each of the U-shaped terminals of the jack is caused to engage an associated one of the terminals in the plug when the plug is inserted into the jack. The plug and the jack have facilities for providing strain relief for both the cords and the individual conductors.
