<p>"ROTARY ELECTRICAL CONNECTOR APPARATUS" A rotary electrical connector apparatus for receiving electrical energy and for 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. The first spindle section has a circular cross sectional area and an outer surface. The spindle also has a longitudinal axis of rotation which coincides with the longitudinal axis of the housing. Means are on the housing and spindle which cooperate to mount the spindle and housing together for rotation about the longitudinal axis. The rotation of the spindle and housing are independent of each other. Means are provided for preventing the longitudinal movement of the spindle in the direction of one end of the housing. A plurality of electrical conducting means for conducting electrical energy through the spindle and which are rotatable 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. Means mounting the electrical contact means for rotational movement with the housing. Means at one end of each electrical contact means for electrically connecting the contact means with electrical energy receiving means. Means at the other end of each electrical contact means for electrically engaging the electrical conducting means contiguous to the outer surface of the spindle's first section and for maintaining the electrical engagement during rotation of one of the spindle and housing relative to each other. The 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 preferably used by releasably mounting the plut end of a telephone cord into the opening of the apparatus and releasably mounting the plug end of the apparatus into the opening of the handset. The connector apparatus can also be inserted into the plug opening at the base of the telephone. Once mounted, the apparatus prevents the handset cord from becoming severely tangled or twisted.</p> |
