Abstract
Abstract A normal force measuring assembly for measuring the normal force exerted by a female receptacle. The force measuring assembly uses a conventional force gauge in which a pair of anvils are used to effect the measurement itself. One of the anvils is fixed. The remaining anvil is movable according to the force exerted by the force gauge and its position is sensed by an optical detector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
A normal force measuring assembly for measuring the normal force exerted by a female electrical connector or the pin of a male electrical connector comprising: a first ball slide having a fixed element and a movable element, first and second anvils aligned together to simulate a pin of an electrical connector, the first anvil being rigidly secured to the movable element and positioned above the second anvil, the second anvil being rigidly secured to the fixed element, an optical position detector having a sensing region defined by a light source and a photodetector, a flag secured to the movable element and extending into the sensing region to permit its position to be detected by the detector, and a force gauge having a force sensing element positioned to support vertically the movable element, said force gauge being positionable vertically to adjust the position of the movable element relative to the fixed element, thereby to separate the anvils and hence the beams of a female electrical connector positioned on the anvils.
Claim 2
Dependent Claim
169 words
A normal force measuring assembly for measuring the normal force exerted by a female electrical connector or the pin of a male electrical connector comprising: a first ball slide having a fixed element and a movable element, first and second anvils aligned together to simulate a pin of an electrical connector, the first anvil being rigidly secured to the movable element and positioned above the second anvil, the second anvil being rigidly secured to the fixed element, an optical position detector having a sensing region defined by a light source and a photodetector, a flag secured to the movable element and extending into the sensing region to permit its position to be detected by the detector, and a force gauge having a force sensing element positioned to support vertically the movable element, said force gauge being positionable vertically to adjust the position of the movable element relative to the fixed element, thereby to separate the anvils and hence the beams of a female electrical connector positioned on the anvils.
Claim 3
Dependent Claim
34 words
A normal force measuring assembly as set forth in claim 1 wherein the force gauge is slidably mounted and which includes a travel platform adapted to adjust the vertical position of the force gauge.
Claim 4
Dependent Claim
30 words
The assembly of claim 2 which also includes a test stand, the first ball slide and travel platform being adjustably mounted thereon and the force gauge being slidably mounted thereon.
Claim 5
Dependent Claim
30 words
The assembly of claim 1 which also includes a test stand, the first ball slide and travel platform being adjustably mounted thereon and the force gauge being slidably mounted thereon.
