Abstract An electrical probe is designed to test printed circuit boards having contact elements and connectors mounted thereon. The probe has an insulating body carrying two parallel contact blades. A member of insulating material is slideably mounted on the blades and is connected to a plunger assembly. The plunger assembly is used to move the member between two positions. In one position, the ends of the blades are exposed for insertion into a connector for engagement with the contact elements therein. Upon movement of the member from this position, the member engages the connector assembly and facilitates extracting the blades from the assembly. In the other position, the member covers the ends of the blades and is shaped to guide the blades into engagement with the contact elements on the board.
For use in testing a circuit board assembly having a conductive rail and at least one upstanding contact pin spaced from said rail, a probe comprising: body of insulating material; a pair of parallel conductive contact blades fixedly mounted on said body and extending beyond one end and being adapted to be conductively engaged with said pin and said rail; an insulating member surrounding and slideably mounted on the extending portion of said contact blades for movement between a first position exposing the end portions of said blades whereby said blades are adapted to be inserted into said circuit board assembly and a second position covering the ends of said blades, said member being shaped so as to guide said contact blades into contact with said pin and said rail when said member is in said second position; and means for moving said member between said positions whereby said member is adapted to engage said circuit board assembly for extracting said contact blades therefrom; and means for connecting said blades to a testing circuit connector.

Claim 3
Dependent Claim
53 words
A probe in accordance with claim 1, wherein said moving means comprises: a plunger connected to said body and to said insulating member, said body and plunger being so sized and shaped as to be manually grasped between the fingers for effecting relative movement between said insulating member and plunger and said body.
Claim 4
Dependent Claim
40 words
A probe in accordance with claim 1, wherein: said member is shaped so as to project beyond the ends of said contact blades and is adapted to engage said pin and said rail for guiding said blades into engagement therewith.
