Filed:

Sep 8, 1982

Appl. No.:

6/416005

Inventors:

Robert E. Staples - Lakeville MA
Joseph A. Ierardi - Norwood MA
Willis E. Golder - Holliston MA

Assignee:

Pylon Company, Inc. - North Attleboro MA

International Classification:

G01R 1512
G01R 102

US Classification:

324 73PC

Abstract:

An automated tester for a wired PC board is adapted to receive a wired PC board and secure it in a predetermined position by vacuum pressure. After the board is fully secured in position, the vacuum pressure applied to a fixture having an array of electrical contacts forces the contacts into position on the contact fingers of the PC board to provide electrical connection through the tester to connectors whereby the board can be tested. The contact array is controlled in position to make contact with the board fingers only after all board motion induced by the vacuum pressure pulldown has ceased, thereby minimizing scraping action between array contacts and PC board fingers. The fixture further includes a linkage arm arrangement which increases the contacting force of the array at the point of making connection to the PC board fingers to augment the reliability of contact.

Assignee:

Augat Inc. - Attleboro Falls MA

International Classification:

G01R 102
G01R 1512

US Classification:

324158F

Abstract:

A high speed edge connector tester having plural edge connector contacting is so movable as to plug and unplug the edge connector contacting probe contacts into and out of the edge connector of a unit under test. Plural automatic testing equipment (ATE) contacting probe contacts mounted to the carriage are individually connected to corresponding edge connector contacting contacts via non-flexing, minimum length electrically conductive wires. The linearly movable carriage, the edge contacting probe-contacts, and the automatic testing equipment contacting probe contacts, are mounted to a test fixture so movable as to electrically connect the ATE contacting probe contacts with the automatic testing equipment. A minimum path length electrical interconnection is established between the automatic testing equipment and the edge connector of the unit under test via the several probes and interconnecting wires.

Appl. No.:

International Classification:

B65H 1720

US Classification:

226192

Abstract:

An adjustable-bow bar or roll axle, useful for spreading slit sheets of paper and for other purposes, includes a hollow cylindrical shell. Two tension bolts extend along axes parallel to the centerline of the shell, and interconnect the ends of the bar or axle. One of the bolts lies in a plane of desired curvature of the bar and applies a bending moment to curve the bar in this plane; this bolt may be located inside or outside the shell, depending on the required bending moment. The second bolt may be inside the shell; its angular position is adjustable with respect to that of the first. This bolt is set in the plane of a resultant force applied to the bar by the tension in the sheet, and applies a bending moment to offset this force and prevent curvature of the bar in this plane. A third bolt may be located in a vertical plane to apply a bending moment to prevent curvature of the bar by its weight; or the second bolt may serve this purpose also.
