Abstract
A rotary electrical connector apparatus for receiving and transmitting electrical energy. The apparatus comprises a hollow housing having opposite ends and a centrally located longitudinal axis of rotation and each opposite end has an opening. A spindle has a first section and a second section. Means on the housing and spindle cooperate to mount the spindle and housing for rotation about the longitudinal axis independently of each other. A plurality of electrical conducting means through the spindle rotate with the spindle. Each of the electrical conducting means comprises a first portion contiguous to the outer surface of the spindle's first section and a second portion extending longitudinally through the spindle's second section. A plurality of electrical contact means each having opposite ends is mounted for rotational movement with the housing. Means at one end of each electrical contact means engage the contact means with electrical energy receiving means. Means at the other end of each electrical contact means engage electrical conducting means contiguous to the outer surface of the spindle's first section and maintain the electrical engagement during rotation of the spindle and housing relative to each other. Second portion of the electrical conducting means comprises means for electrically connecting the conducting means to the electrical energy transmitting means. The connector apparatus is used between a telephone and handset cord and prevents the handset cord from becoming twisted.
