Abstract: A pin cutoff tool employs shears to sever pins. The pin cutoff tool is formed in a pliers-like configuration, with working surfaces formed within the jaws, and a pair of handles situated in working arrangement opposite a pivot point to provide leveraging advantage to the shearing surfaces. Stops may be formed within the jaws to limit the amount of closing travel, and to limit the amount of opening travel. The closing stops also may be formed such that, when closed, the inner surfaces of the jaws are substantially equal to the width of a pin being cut. Grooves may be formed in the jaws to accommodate neighboring, closely situated pins, and the jaws may be relatively narrow, so that neighboring pins in a direction orthogonal to the axis of the channels are not disturbed by the tool when shearing a pin.

Abstract: An arrangement for repairing a backplane assembly having a backplane pin is disclosed. The arrangement includes an actuation assembly having a housing and a biasing mechanism. The arrangement also includes a pin engaging member having a tip for engaging the backplane pin. The pin engaging member is (i) secured to the housing and (ii) mechanically coupled to the biasing mechanism so that the pin engaging member is reciprocally movable relative to the housing between (1) a retracted position in which the tip of the pin engaging member is urged toward the housing and (2) an extended position in which the tip of the pin engaging member is urged away from the housing. An associated method of repairing an electrical assembly is also disclosed.

Abstract: An annular insulator is positioned around a compliant contact section of a replacement contact pin for a header contact pin connector prior to insertion of the replacement contact pin through a header pin mounting hole and then both the replacement pin and the annular insulator being carried by the replacement pin are simultaneously pounded into snug received relationship within an associated pin receptor connector hole. A header contact pin repairing fixture has a plurality of size reducing holes for reducing the cross sectional dimension of the compliant section, one of which has an insulator end receiving opening for nesting receipt of a tapered wall at the end of the insulator to hold it in an upright orientation above and in alignment with the smallest sizing hole during insertion of the replacement pin into the insulator bore.
