ABSTRACT:
A connector to prevent tangling of a cord having modular plug at its end which is to be connected to a telephone handset. The connector includes a first part which is rotatable relative to a second part. A circular printed circuit board with circuit conductors laid thereon is mounted on a mounting base of the first part. The modular plug with its conductive laminates which are in contact with the circular circuit conductors on its rear surface is extended from the mounting base. The second part includes a shell having a plurality of holes therein in line with the circuit conductors. A wire guide is pressed onto the top portion of the shell. The wire guide and shell form and acute inclined angle receptacle for accepting a modular type plug which is separate from the connector. Spring wire contact elements fixed inside the wire guide are electrically connected to a plurality of spring loaded contact assemblies. Each of the spring loaded contact assemblies is inserted through the respective hole and then contact one circuit conductor on its front surface. This makes individual electrical contact between the circuit conductors and respective spring wire contact elements.
