Abstract: A sealed electrical connector employs electrical contacts located in a housing with multiple contact receiving apertures, deflectable latches, and a seal section. A wire seal is mounted on the seal section, and a seal retainer is latched to the housing to retain the wire seal within the seal retainer and on the seal section. Wire seal sections are positioned within a seal retainer chamber with sufficient annular and radial clearance to permit deflection of the seal section due to transverse forces on the wires, without affecting the seal integrity around the wires. A lock plate is attachable to a housing mating face initially in a pre-staged position and shiftable to a locked position to prevent undesired deflection of the contact latch. The lock plate includes a tab forming an interference fit in a housing slot to hold the lock plate in either the pre-staged position or the locked position.

Abstract: An electrical connector assembly (10) includes a connector position assurance device (20), a plug housing (30), and a receptacle housing (40). The connector position assurance device (20) includes a central beam having a central detent (22b) thereon with an end section (22c) for engaging a front section (35) of plug housing (30) when the CPA is in a fully advanced position. A web (24) includes a radiused profile (24a) for flexing and avoiding damaging stress concentrations in the web (24) when the CPA (20) is in the fully advanced position. Double locking and connector position assurance are achieved, and the CPA (20) can be latched to the plug housing (30) in a pre-engagement position for preventing inadvertent withdrawal of the CPA (20) from the plug housing (30).

Abstract: Stamped and formed terminal receptacle for a printed circuit board comprises a hollow tubular receptacle portion, a transition portion, and a mounting portion. The tubular receptacle portion has a lead-receiving upper end and contains a hairpin type spring which extends downwardly from one wall of the receptacle and is reversely bent so that it extends upwardly toward the lead-receiving end. The tip of this spring is formed laterally of the axis of the receptacle to provide an inclined lead-in surface for the lead. The transition portion has features which prevent the flow of solder into the receptacle portion during soldering and the mounting portion has improved means for holding the terminal in the hole on the printed circuit board during handling prior to wave soldering.

Abstract: An eyelet-shaped type connector for connecting together opposite sides of a printed circuit board and having a first end section of a generally cylindrical shape extending out of one side of a hole in a printed circuit board and a second end section of a generally cylindrical shape extending out of the other side of the printed circuit board. A plurality of legs, bowed towards each other, connect the two end sections together. Because the legs are bowed inwardly they will give and become more bowed as the extended first and second ends are soldered to conductive areas around the holes in the printed circuit board and the board contracts after the solder has cooled, thereby eliminating cracking of the solder joints. The inside surfaces of the connector are coated with a soldering repellant material such as chromium and the outside surfaces with a solder attracting coating such as tin.

Abstract: A first half of a two piece connector housing has a plurality of parallel tubular elements extending from a common backing and defining a plurality of first cavities, each containing a hermaphroditic contact. The second half of the housing has a grid-like network of partitioning walls which define a plurality of second cavities and which fit in-between the tubular members of the first half. Each second cavity also contains one of said hermaphroditic contacts which mates with an aligned hermaphroditic contact in a cavity in the first housing half. Each contact has a trough-like element and a pair of leaf-like spring elements mounted thereon. Two such contacts will mate when inverted with respect to each other, with the leaf-like elements of one contact mating with the inner surfaces of the trough-like elements of the other contact to provide four separate areas of electrical conduction.
