US Patent:

46671552, May 19, 1987

Filed:

Jan 7, 1986

Appl. No.:

6/816896

Inventors:

Russell E. Coiner - Staunton VA
Henri T. Burgers - Grottoes VA
Jeffery P. Stowers - Afton VA

Assignee:

Virginia Panel Corporation - Waynesboro VA

International Classification:

G01R 3128
G01R 1512

US Classification:

324158F

Abstract:

A vacuum test fixture for the in-circuit and functional testing of loaded printed circuit boards is disclosed. Key components of the test fixture are made from inexpensive state-of-the-art structural plastics under new molding techniques. As a result, a much lighter, more convenient, more compact and considerably less expensive vacuum test fixture is realized without loss of dimensional precision and stability in the most vital components of the fixture. The fixture is constructed to be snapped together and retained by a unitary structurally sound molded trim frame which is lightweight and durable and can be manipulated without tools. An effective seal is established between a top plate and an insert retainer for a lower plate of the fixture by an adhesive-free from fitting neoprene gasket which embraces the margin of the top plate. To create an air seal between the PCB and vacuum test fixture, a closed cell double skin neoprene pad is adhesively attached to the top plate of the fixture. Manually operated thumb screws are used to secure the bottom plate of the fixture removably in the molded insert retainer.

Appl. No.:

Inventors:

Russell E. Coiner - Staunton VA
Thomas W. Moore - Fisherville VA

Assignee:

Virginia Panel Corporation - Waynesboro VA

International Classification:

H01R 414

US Classification:

339276A

Abstract:

An integral holding shell and wire wrap post for spring contacts is disclosed wherein the unitary product is formed by metal drawing operations instead of by separate machining and crimping operations previously carried out to connect the post to the holding shell. The product is gas-tight for a positive seal when used in vacuum test fixtures. Mechanical connections between the wire wrap post holding shell are eliminated, making the product more electrically sound. Manufacturing cost is reduced.
