Abstract

A chassis mountable coaxial cable connector assembly having an isolated ground. A connector pin is attached to the center wire of the coaxial cable with insulation surrounding the connector pin to prevent unwanted signal attenuation to a housing of the connector assembly. The housing is connected to the shielding braid of the coaxial cable with the shielding braid and housing forming a floating type ground. The cable connector assembly includes a unitary constructed flanged cylinder with a threaded portion for mounting the connector assembly in a chassis and, simultaneously, isolating the housing from the chassis.

Claims

1. A coaxial connector with an isolated ground, said coaxial connector comprising:

a connector pin for mating with a connector to allow an electric signal to feed therethrough;

a conductive housing axially surrounding said connector pin;

means between said conductive housing and said connector pin for electrically isolating said housing from said pin, said isolation means being formed of two parts and fixed with reference to said housing;

a unitary, non-conductive cylinder having a radially extending flange on one end and a threaded section on the other end and being radially disposed about said conductive housing;

a nut engageable with said threaded section to securely mount said coaxial connector in a hole in a chassis with said nonconductive cylinder electrically isolating said conductive housing from the chassis;

an end portion of said conductive housing being deformed radially outwardly into engagement with said non-conductive cylinder to secure said cylinder in position on said housing; and

terminal means on said conductive housing providing for an electrical connection thereto to establish a floating electrical ground with respect to said connector pin.

2. The coaxial connector as recited in claim 1 wherein:

said non-conductive cylinder is made of a hard-molded, non-conducting resilient material.

3. The coaxial connector, as set forth in claim 1 wherein said unitary, non-conductive cylinder is made from a plastic that will withstand at least 15 inch-pounds torque and 30 pounds pull when mounted.

4. The coaxial connector set forth in claim 1 and further including:

a first annular electrically non-conductive member interposed between said conductive housing and said connector pin and defining one of said two parts of said isolation means;

a second annular electrically non-conductive member defining the other of said two parts and interposed between said conductive housing and said connector pin; and

fastening means operatively connected to said conductive housing and engageable with said second annular non-conductive member for holding said first and second annular non-conductive members in fixed relative positions with respect to said conductive housing.

5. The coaxial connector set forth in claim 1 wherein:

said terminal means in a tab integral with said conductive housing and extending axially therefrom.
