Abstract

A rotatable connector installed in a telephone transmitter and used for connecting a coiled conductor and the transmitter to effectively prevent the coiled conductor from twisting. The connector includes a housing, four conductors for connecting to a microphone and a receiver in the transmitter, four annular guide pieces which can be mounted on a rotation seat and held in the housing and composed of four semicircular piercing guide pieces and four semi-circular guide pieces, a jack for the coiled conductor held in the housing and having several electrically conducting spring strips thereon. The jack can be freely rotated relative to the housing while keeping the spring strips in electric contact with the corresponding annular guide pieces.

Claims

1. A rotatable connector for a telephone transmitter comprising:

a housing, a rotation seat, a plurality of annular guide pieces, a jack adapted to receive a transmitter conductor, and a plurality of electrically conducting spring strips;

wherein

said housing includes a hollow interior and has two insertion holes on a first end thereof;

said jack includes a central cavity at a first end thereof to receive said transmitter conductor, and said jack further includes two insertion holes on a second end thereof to receive said insert insertion hooks on said housing, a top surface of said jack includes a recessed area with axial slots on a top surface thereof, said axial slots being adapted to receive axial projections on a lower surface of a lid, the recessed area further including on each side a groove adapted to receive a tongue included on each side of said lid;

said rotation seat including four conductors extending from a forward end, and further including four annular grooves on a rear portion thereof, each annular groove including a through notch, each said notch occupying a different circumferential position;

each said annular guide piece including a semi-circular piercing guide with a piercing member and a semi-circular guide piece, each said annular guide piece being received in a corresponding annular groove, with the piercing member of the piercing guide piece being received in said through notch of said groove, said piercing members piercing insulative layers of said conductors to form electrical connection therewith;

said electrically conducting spring strips being four in number, and being kept in position in said axial slots on said top surface of said jack, said spring strips being different in length and having front and rear ends that bend downward, said front ends each being in tangential sliding contact with a corresponding annular guide piece.
