Abstract

A coaxial connector is disclosed for simultaneous crimping of the center conductor and outer shield made possible by a port hole design of the connector allowing for visual inspection of the center contact, the center conductor and the insulation layer of the cable, the port hole design further permitting orientation and entry of the crimping dies.

Claims

1. In a coaxial connector, wherein a center conductor and outer shielding are crimped simultaneously, and a portion of the connector is provided with port holes exposing a central electrical contact for crimping on the center conductor, the improvement comprising:

a medial portion of the connector being larger in cross section than a rearward portion and smaller in cross section than a forward portion of said connector, the forward portion having a dielectric insert and an electrical contact, the medial portion being substantially hollow and providing a shoulder against which the insert is seated, a hollow barrel portion of said contact supported by said insert and projecting in cantilever configuration into free space within said medial portion, said rearward portion having electrical shielding of a coaxial cable received thereover, a ferrule received over said electrical shielding and stopped against said medial portion, a center conductor of said coaxial cable supported in said rearward portion by an insulation layer of said coaxial cable, said conductor projecting into said medial portion and received in said barrel portion, said medial portion provided with opposed port holes exposing said center conductor, said insulation layer and said barrel portion, and said medial portion provided with two flat surfaces alternately spaced with said port holes around the periphery of said medial portion, said flat surfaces providing for nesting of the connector between walls of a crimping die which is enterable within one said port hole.
