Abstract

A rotating collar lock connector for terminating the end of a coaxial cable in which all of the metal parts therein are either stamped and formed or drawn, as opposed to being machined. Further, since no solder is required and since assembly is accomplished entirely from one direction the connector can be assembled at a single rotary type assembly machine. The connector comprises a rear metal sleeve which receives the coaxial cable at a first end thereof. A rotatable metal collar has a flanged first end which is slipped over the first sleeve from the second end thereof until it abuts against protuberances formed on the surface of the first sleeve near said first end. A metal spring means, such as a spring washer, is then slipped over the first sleeve up to said collar flange. The flanged first end of a second metal sleeve is then press fitted over the second end of the first sleeve and against the spring washer to lock the collar on the first sleeve in such a manner that the spring washer provides a spring bias between the flanges of the collar and the second sleeve. A cylindrically-shaped dielectric spacer having a concentric aperture extending therethrough is then press fitted within the first and second sleeves. A generally cylindrical male terminal is then crimped around the stripped center conductor of the cable and subsequently press fitted into the aperture in the dielectric spacer of the connector. The cable braid is secured around the first end of the first sleeve by means of a metal ring which is crimped therearound.

Claims

1. A connector for a coaxial cable, comprising:

A seamless metal first shell having a reduced cylindrical first section and an enlarged cylindrical second section provided with a lip,

said first shell having a radial shoulder at the junction of said first and second sections,

a one piece dielectric spacer having a reduced cylindrical first portion slideable along and intimately encircled by said second section and impinged against said shoulder,

said spacer including an enlarged cylindrical second portion projecting outwardly of said second section and having a radial shoulder seated against said lip,

a coupling sleeve having at one end a radially inwardly projecting flange freely rotatably received over said second section,

a seamless second shell slideably received over and intimately encircling said second portion and said second section and being press fit over said second section,

a radially outwardly projecting flange on said second shell cooperating with the flange of said sleeve to form an annular cavity,

a spring washer received in said cavity,

said spacer having a coaxial bore therethrough provided with a first counterbore in an end of said first portion and second counterbore in an end of said second portion,

a coaxial cable having a center conductor protruding from an end of an encircling dielectric layer and an encircling conductive sheath,

said sheath being received over said first section and being electrically connected thereto,

said center conductor being connected to an elongated metal contact,

said contact being slideably received in said bore and projecting outwardly into said second counterbore, and

said end of said dielectric layer projecting through said first section and being intimately encircled by said first counterbore.
