Abstract

Fragile and expensive test probe cables are protected from destruction by pinching, bending, etc. A capstan pressure roller drive, available to all cables independently, stuffs each cable into a separate random-fold bin when a rotatable drive roller contacts a rotating drive shaft. A large number of cables may each be independently drawn from their respective bins for use. The drive shaft is actuated only during the retract operation, to reduce probe wear. Each probe may separately be returned to its bin by rotating a frame about its pivot against spring tension. This brings the drive roller against the drive shaft, which is rotated by a motor when the switch is activated by the frame. The probe is withdrawn into the bin until the frame is manually released.

Mechanism for Retrieving and Storing Probe Cables

Fragile and expensive test probe cables are protected from destruction by pinching, bending, etc. A capstan pressure roller drive, available to all cables independently, stuffs each cable into a separate random-fold bin when a rotatable drive roller contacts a rotating drive shaft. A large number of cables may each be independently drawn from their respective bins for use. The drive shaft is actuated only during the retract operation, to reduce probe wear. Each probe may separately be returned to its bin by rotating a frame about its pivot against spring tension. This brings the drive roller against the drive shaft, which is rotated by a motor when the switch is activated by the frame. The probe is withdrawn into the bin until the frame is manually released. The probe slips against the drive roller if tension is supplied to the probe at any time, preventing damage to the probe.

The force required to rewind the probe is generated by the operator and, thus, releasing the rewind lever will stop the rewind operation. The operation can be stopped and restarted at any time and independently for any number of cables. The mechanism exerts no force upon a cable unless actuated, and there is no possibility of accidentally retracting a cable.
