Coaxial connector
First Claim
1. An electrical connector member particularly suited for use with a coaxial cable having a center conductor and an outer conductor separated by a relatively soft inner dielectric core comprising:
- a conductive shell having a forward mating end and a rear termination end adapted to be connected to the outer conductor of the cable, said rear termination end having a bore therethrough and a rear annual surface;
an insulator in said shell containing a center contact adapted to be connected to the center conductor of the cable;
a hollow bushing having a front, a rear, a forward portion and a rear portion, said bushing being partially inserted into said bore from the rear of said sheel leaving said rear portion exposed, the outer conductor of the cable being adapted to be laid over said rear portion of said bushing;
said bore of said shell having an annular recess;
said rear portion of said bushing having a forward facing annular shoulder abutting said rear surface of said shell, and said forward end of said bushing having a radially deflectable flange engaging said annular recess thereby providing a positive interlock between said bushing and said shell; and
a sleeve surrounding said rear portion of said bushing adapted to be crimped to secure the cable outer conductor to said bushing.

Abstract
A coaxial connector having precise matched impedance characteristics which is suitable for use with coaxial cable having a very soft dielectric core. A slotted bushing is fit over the core of the cable. The bushing is inserted into the rear of the coaxial contact assembly. A flange on the front of the bushing snaps into a recess in the wall of the coaxial contact assembly to provide a positive interlock and establish an optimum electrical path in the outer conductor circuit for high frequency performance. A sleeve is crimped down around the outer conductor of the cable which is laid over an exposed, rigid rear portion of the bushing and the rear of the coaxial contact assembly, neither of which is deformed during the crimping operation.

9. An electrical termination comprising:
-
an electrical connector member; a coaxial cable having a center conductor and an outer conductor separated by a relatively soft inner dielectric core; a conductive shell having a forward mating end and a rear termination end, said rear end being connected to the outer conductor of said cable, said rear end having a bore therethrough and a rear annular surface; an insulator in said shell containing a center contact connected to the center conductor of said cable; a hollow bushing haivng a front, a rear, a forward portion and a rear portion, said forward portion being partially inserted into said bore from the rear of said shell leaving said rear portion exposed, the outer conductor of said cable extending over said rear portion of said bushing; said rear portion of said bushing having a forwardly facing annular shoulder abutting said rear surface; said bushing having longitudinally extending slots in the wall thereof extending rearwardly from said front of said bushing whereby said forward portion of said bushing is radially contractible, and having an outwardly extending flange on said forward portion thereof; an annular recess in said bore of said shell adapted to receive said flange therein to provide a positive interlock and a positive electrical contact point in said annular recess; and a sleeve surrounding said rear portion of said bushing and said outer conductor, said sleeve being crimped to secure said cable outer conductor to said bushing. - View Dependent Claims (10, 11, 12, 13)
