Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
237 words
A high-speed edge connector assembly for providing testing of an electronic circuit device having circuit points to be tested and an edge connector having contacts to be tested, comprising: a test fixture having a movable electronic circuit device receiving face and a stationary probe support face; a first plurality of spring-loaded probes fastened to the probe support plate for providing a first plurality of stationary signal contacts defining an array for testing the circuit points of the electronic circuit device; a right angled connector fastened to the electric circuit device receiving face having first and second pluralities of contacts in respective planes defined at a right angle to each other; a second plurality of spring-loaded probes having ends fastened to the probe support plate for providing a second plurality of stationary signal contacts defining an array for connecting with said first plurality of contacts of said right-angled connector; a third plurality of spring-loaded probes at least equal in number to the number of the contacts of the edge connector; a fourth plurality of spring-loaded probes at least equal in number to the number of said third plurality of spring-loaded contacts; and means coupled to the third and fourth pluralities for so moving said fourth and said third pluralities of spring-loaded contacts that said third plurality of spring-loaded contacts selectively connects with said edge contacts, and said fourth plurality of spring-loaded contacts selectively connects with said second contacts.
Claim 2
Dependent Claim
237 words
A high-speed edge connector assembly for providing testing of an electronic circuit device having circuit points to be tested and an edge connector having contacts to be tested, comprising: a test fixture having a movable electronic circuit device receiving face and a stationary probe support face; a first plurality of spring-loaded probes fastened to the probe support plate for providing a first plurality of stationary signal contacts defining an array for testing the circuit points of the electronic circuit device; a right angled connector fastened to the electric circuit device receiving face having first and second pluralities of contacts in respective planes defined at a right angle to each other; a second plurality of spring-loaded probes having ends fastened to the probe support plate for providing a second plurality of stationary signal contacts defining an array for connecting with said first plurality of contacts of said right-angled connector; a third plurality of spring-loaded probes at least equal in number to the number of the contacts of the edge connector; a fourth plurality of spring-loaded probes at least equal in number to the number of said third plurality of spring-loaded contacts; and means coupled to the third and fourth pluralities for so moving said fourth and said third pluralities of spring-loaded contacts that said third plurality of spring-loaded contacts selectively connects with said edge contacts, and said fourth plurality of spring-loaded contacts selectively connects with said second contacts.
