Abstract

A pin/socket, pin/pin triaxial interface contact assembly is disclosed which features a minimum number of contacts and insulators which are metal staked to form a contact assembly for mating with concentric twinaxial or triaxial contacts. The assembly is cost effective and withstands significantly high temperatures without degrading the assembly or the positioning of the several components thereof as would otherwise be the case.

Claims

1. An interface contact assembly comprising:

an inner contact;

an inner insulator concentrically surrounding the inner contact;

an intermediate contact concentrically surrounding the inner insulator;

first means arranged with the intermediate contact and the inner contact so that when the intermediate contact is staked the inner insulator is compressed into the inner contact to provide an initial assembly;

an outer insulator concentrically surrounding the intermediate contact;

an outer contact concentrically surrounding the outer insulator; and

second means arranged with the intermediate insulator so that when the outer contact is staked the outer insulator is compressed into the intermediate contact to provide a final assembly.

2. An interface contact assembly as described by claim 1, wherein the first means includes:

the intermediate contact having an outer diameter with an undercut thereon and an inner diameter;

the inner contact having an outer diameter with ring grooves thereon in the area of the undercut; and

the intermediate contact being staked in the undercut, whereupon a portion of the intermediate contact inner diameter compresses the inner insulator into the inner contact ring grooves to provide the initial assembly.

3. An interface contact assembly as described by claim 1, wherein the second means includes:

grooves on at least one end of the outer diameter of the intermediate contact so that when the outer contact is staked in the area of said grooves at least one portion of the outer contact compresses the outer insulator into said grooves to provide the final assembly.

4. An interface contact as described by claim 1, wherein:

the inner contact is a pin/socket contact.

5. An interface contact as described by claim 1, wherein:

the inner contact is a pin/pin contact.

6. An interface contact assembly, comprising:

an outer contact having inner and outer diameters;

an outer insulator surrounded by the outer contact;

an intermediate contact surrounded by the outer insulator and having inner and outer diameters;

an inner insulator surrounded by the intermediate contact;

an inner contact, surrounded by the inner insulator and having an outer diameter;

the inner contact, the inner insulator and the intermediate contact disposed in concentric relation to each other;

first means associated with the intermediate contact and the inner contact so that when the intermediate contact is staked a portion of the inner diameter thereof compresses the inner insulator into the inner contact to provide an initial assembly;

the outer insulator and the outer contact being disposed in concentric relation to the initial assembly; and

second means associated with the intermediate contact so that when the outer contact is staked a portion of the inner diameter thereof compresses the outer insulator into the intermediate contact to provide a final assembly.

7. An interface contact assembly as described by claim 6, wherein the first means includes:

an undercut on the outer diameter of the intermediate contact;

ring grooves disposed on the outer diameter of the inner contact within the area of the undercut;

the intermediate contact being staked at the undercut, whereupon a portion of the inner diameter of the intermediate contact compresses the inner insulator into the inner contact ring grooves to provide the initial assembly.

8. An interface contact assembly as described by claim 6, wherein the second means includes:

grooves on at least one end of the intermediate contact so that when the outer contact is staked in the area of the grooves a portion of its inner diameter compresses the outer insulator into said grooves to provide the final assembly.

9. An interface contact assembly as described by claim 8, wherein:

the outer insulator includes a first member extending to one end of the outer contact and a second member extending to the opposite end thereof;

said first and second members abutting each other to form a continuous outer insulator;

the grooves are at one end of the intermediate contact and at the opposite end thereof; and

the outer contact is staked at its one and opposite ends in the respective areas of the grooves at the one end and the opposite ends of the intermediate contact so that corresponding portions of the inner diameter of the outer contact compress the first and the second outer insulator members into corresponding grooves to provide the final assembly.

10. An interface contact assembly, comprising:

an outer contact having inner and outer diameters;

an outer insulator surrounded by the outer contact;

an intermediate contact surrounded by the outer insulator and having inner and outer diameters, and having an undercut on one section of its outer diameter and grooves on at least one end thereof;

an inner insulator surrounded by the intermediate contact;

an inner contact surrounded by the inner insulator, and having an outer diameter and ring grooves on said outer diameter;

the inner contact, the inner insulator and the intermediate contact disposed in concentric relation to each other;

the intermediate contact being staked at its undercut in the area of the inner contact ring grooves, whereby a portion of the inner diameter thereof compresses the inner insulator into said ring grooves to provide an initial assembly;

the outer insulator and outer contact disposed in concentric relation to the initial assembly; and

the outer contact being staked on its outer diameter in the area of the intermediate contact grooves, so that a portion of its inner diameter compresses the outer insulator into said grooves to provide the final assembly.

11. An interface contact as described by claim 10, wherein:

the inner and outer insulators are of a material which permits compression of said insulators into the grooves and ring grooves, respectively.
