Abstract
Abstract A coaxial connector which is especially suitable for use in CATV systems in which the connector contains an integral terminating resistor. The connector includes a hollow body surrounding an insulator assembly within which is disposed a spring contact assembly. The spring contact assembly includes two spring contact fingers normally biased to a first position, but which are adapted to be displaced to a second position upon the insertion of a coaxial cable center conductor therebetween. The terminating resistor has one of its leads connected to the connector body. The other lead of the terminating resistor makes direct electrical and mechanical contact to one of the spring contact fingers when the fingers are in the first position but the terminating resistor is mechanically and electrically disconnected therefrom when the spring contact fingers are displaced to the second position.

Claim 3
Dependent Claim
48 words
A coaxial connector in accordance with claim 1 in which said body has a coaxial cable center conductor receiving opening in one of its ends, and including a sealing member adjacent the one of said body ends with an interface integrally joining said sealing member to said body.
Claim 4
Dependent Claim
42 words
