Abstract
Abstract A rotatable electrical connector for preventing twisting and kinking of cords such as telephone and portable appliance cords includes a shell having an open-ended cylindrical bore with a series of contact elements projecting radially inwardly from the wall of the bore and a barrel rotatably received and retained in the bore with the circumference of the barrel having a series of contact rings in alignment with the contact elements. First and second electrical connectors are provided on the ends of the shell and the barrel, respectively, with the corresponding contacts electrically connected through the contact elements and contact rings.

Claim 1
Independent Claim
313 words
A rotatable electrical connector for use with flexible cords to prevent twisting and kinking thereof comprising: a. a shell of molded plastic material having a cylindrical side wall and an end wall together defining a cylindrical bore extending axially inwardly from one end thereof, a first electrical connector extending from said end wall and having a plurality of electrical contact members, an equal plurality of electrical contact elements carried by and projecting radially inwardly from said cylindrical wall, and an equal plurality of conductors each connecting one said contact member to one said contact element; b. a barrel of molded plastic construction, of a diameter slightly less than that of said bore and having an equal plurality of electrical contact rings on the circumference thereof in alignment and engagement with said contact elements, a second electrical connector of complementary configuration to said first electrical connector extending inwardly from an end of said barrel and having an equal plurality of electrical contact members, and an equal plurality of conductors each connecting one of said last mentioned connectors to one of said rings; c. means for rotatably retaining said barrel in said shell; d. means for retaining said barrel comprises a retainer cap having a top wall partially overlying the end wall of said barrel, an annular side wall and a radially inwardly projecting flange connected to said side wall in spaced relation to said top wall, the cylindrical wall of said shell having a cooperating, radially outwardly projecting flange adjacent the open end of said shell; and e. said shell includes an inner cylindrical member having an equal plurality of holes therethrough in alignment with said rings of said barrel, said contact elements comprising wire end portions projecting radially inwardly through said holes, and said shell further includes an outer cylindrical member closely overlying said inner member and biasing said wire ends radially inwardly.
