Abstract
Abstract A probe device including a unitary body 2 and a sliding plate means 44 for testing and diagnosing multi-lead electrical flat packs. The sliding plate means contains two sets of holes 52 into which are inserted spring-loaded electrical contact probes for making contact with the leads of the electrical flat pack. The unitary body 2 includes comb teeth for orienting the unitary body over the leads of the electrical flat pack, as well as gripping means having hook ends for securely fastening the probe device to the electrical flat pack being tested or diagnosed. The gripping means include an outwardly flared portion against which the sliding plate means exerts inward lateral pressure causing the hook ends to grip underneath the electrical flat pack at each corner thereof to securely clamp it in place. Included in unitary body 2 is at least one threaded hole which is sufficiently large to allow a size 4-40 machine screw to pass therethrough.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
A probe holding device for attachment to a multi-lead electrical flat pack soldered to a printed circuit board to permit testing thereof, said probe holding device comprising; (a) a generally rectangular unitary body having at each corner gripping means for clamping said unitary body to said electrical flat pack; (b) an outwardly extending flared portion defined on each of said gripping means; (c) sliding plate means having two oval cavities extending therethrough, each oval cavity surrounding a pair of said gripping means and free to relatively move along said gripping means for exerting lateral pressure on said flared portion of said gripping means to maintain said unitary body in a clamped relationship with said electrical flat pack; and, (d) contact probe holding means defined on said sliding plate means for holding a plurality of contact probes.
Claim 2
Dependent Claim
136 words
A probe holding device for attachment to a multi-lead electrical flat pack soldered to a printed circuit board to permit testing thereof, said probe holding device comprising; (a) a generally rectangular unitary body having at each corner gripping means for clamping said unitary body to said electrical flat pack; (b) an outwardly extending flared portion defined on each of said gripping means; (c) sliding plate means having two oval cavities extending therethrough, each oval cavity surrounding a pair of said gripping means and free to relatively move along said gripping means for exerting lateral pressure on said flared portion of said gripping means to maintain said unitary body in a clamped relationship with said electrical flat pack; and, (d) contact probe holding means defined on said sliding plate means for holding a plurality of contact probes.
Claim 3
Dependent Claim
