ABSTRACT:
This specification describes an improvement in miniature plugs that are used for connecting together a telephone handset to a jack in the base of a telephone, and for connecting the base to a wall outlet or jack. Such plugs, particularly when used for handset cords, are pulled and flexed during normal use, and this causes movement that results in damage to contacts in miniature plugs so that reception becomes progressively more noisy, and the miniature plug has to be eventually replaced. This invention provides an effective structure for eliminating the motion and the problem that the motion causes.
