Abstract: A pin header has pin contacts (12)(12A, 12B) insert-molded in a parallelepiped insulating housing (13), and penetrating it to form upper and lower rows. Each contact is integrally composed of a plugging rod (14) extending horizontally and forwardly of the housing, a leg (15)(15A, 15B) and a generally straight rearward extension (16).

Abstract: A pick-and-place cap is provided for a connector having bail latches. The pick-and-place cap includes an elongate board having upper and lower surfaces. Two catches are formed on opposite end portions of the board and extend from the lower surface thereof. Each catch forms a barb for engaging a corresponding latch of the connector thereby attaching the pick-and-place cap to the connector and securing the latches with respect to the connector. Two grooves are defined in the upper surface of the flat board between a middle portion and each of the end portions to allow pivotal movement of the middle portion with respect to the end portions which drives the end portions to disengage the catches from the latches and thus releasing the latches and the connector. A collapsible, hollow barrel is formed on the lower surface of the middle portion to support the middle portion at a position where the catches remain engaged with the latches.

Abstract: Electrical connections between a cable connector and an electronics module—that has a corresponding panel connector—are made/broken quickly and easily with a light, low-bulk half-shell that is an exclusively mechanical, nonelectrical intermediary from connector to module. A rack receives and holds the module, and a connector holder, formed in the rack, receives and holds the cable and panel connectors aligned. A cam is associated with the rack or module, and a cam-follower with the other—preferably in duplicate opposed sets. A single, one-hand-actuated lever on the rack or module operates the cam or follower to bodily shift module vs. rack and engage/disengage the connectors. Preferences: each holder easily and quickly engages/disengages from a corresponding cable connector. Typically a module weighs at least several pounds. The cam has a concave arcuate segment to draw the module in and seat the connectors, and a convex arcuate segment to eject the module and unseat them.
