Abstract: An insertion/extraction mechanism is used to cause blind mateable electrical connectors on an electrical module to engage and disengage mating electrical connectors in a housing by forcing the module to and from its fully inserted position within the housing. The mechanism includes a U-shaped handle pivotally mounted to the module at its ends through elastomeric sleeves. The sleeves are each mounted in a mounting hole in the module and each has a central bore within which a mounting shaft, extending from the handle, is housed. Each end of the handle has a camming surface which engages a pivot pin carried by the housing as the handle is pivoted while inserting the module into and withdrawing the module from the housing. This engagement of the camming surfaces and the pivot pins causes the handle ends and the associated mounting shafts to push radially against the elastomeric sleeves as the handle is pivoted during insertion and extraction.
