Abstract: An electrical header receptacle (10) is provided to be connected to a printed circuit board (11) and to be mounted in an enclosure (12). A housing (13) has a well (20) formed on the first side (16) of the base (15) of the housing (13). A metal shield (25) covers the second side (17) of the base (15) and is crimped over the base (15) so that a portion of the metal shield (15) covers a portion of the first side (16) of the base (15). A plurality of spaced-apart male contact pins (14) extend through respective openings in the metal shield (25) and base (15) exiting from the well (20) in the base (15). A sealant (33) is disposed in the well (20) and forms a waterproof seal about the plurality of male contact pins (14). The male contact pins (14) extend outwardly from the metal shield (25) and pass through an electromagnetic interference filter (35) and are connected to the printed circuit board (11).

Abstract: A member (13) with a shorting contact (14) thereon is disposed in a receptacle housing (11). The shorting contact (14) is in mating electrical contact with an interface (15). When a header (12) is inserted into the receptacle housing (11), an inclined portion (29) of a beam (28) formed on the header (12) deflects the shorting contact (14) and opens the electrical circuit between the shorting contact (14) and the interface (15). Male pin contacts (25) in the header (12) electrically engage female contacts (21) within the receptacle housing (11) before the shorting circuit is broken. When the header (12) is removed from the receptacle housing (11) the shorting circuit is closed before electrical contact is opened between the male pin contacts (25) and the female contacts (21). In this manner, spurious signals are prevented.

Abstract: High density electrical interconnections are established by using an electrical connector comprising a plurality of terminals held in position by resilient housing latches and by a separate terminal position assurance insert which is formed as part of a one-piece member also having a connector position assurance insert. The terminals position assurance insert is inserted into the housing from the rear and abuts a projection on each terminal thus assuring that the resilient housing latch engages the terminal. A connector position assurance insert attached to the terminal position by a integral strap is inserted beneath a connector latch to prevent the depression of the latch. A strap is deformed so that the connector position assurance insert is located parallel to and adjacent to the terminal position assurance insert when the two are fully seated in the connector.
