An electrical connector seal cap assembly (10), includes a seal cap (20) with a seal cap gasket (28) bonded thereto, which cap is assembled to an electrical connector (30). The seal cap (20) is pressed into engagement with the electrical connector (30) by action of screw (19). As this occurs, seal cap gasket (28) is sealingly pressed against sealing interface surface (38) of electrical connector (30). Gussets (22) of seal cap (20) advantageously distribute the compressive forces generated by screw (19) in the area of the interface between seal interface (38) and seal cap gasket (28) thereby creating an effective seal against sprays or other air-borne, high velocity contaminants.

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). The plurality of male contact pins (14) are joined to the electromagnetic filter (35) to prevent passage of electromagnetic interferences therethrough. The electromagnetic filter (35) may be mounted vertically or horizontally with respect to the metal shield (25) and is electrically connected to the metal shield (25). A flange seal (40) is disposed between the first side (16) of the base (15) and the enclosure (12) to provide a waterproof seal. The portion of the metal shield (25) on the first side (16) of the base (15) makes electrical contact with the enclosure (12).

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. The terminal position assurance insert is inserted immediately adjacent a side wall of the connector housing on which the connector latch is mounted and above a wire crimp and insulation barrel portion to the rear of the projecting section of the terminal. Both the terminal position assurance insert and the connector position assurance insert include laterally deflectable latching springs for retention in the housing.
