Abstract: A socket for interconnecting an electronic module to a circuit board includes an insulative housing having a plurality of terminals applying a moment to the module. A U-shaped latch is positioned within a pocket at each end of the insulative housing. The U-shaped latch is of metal and has two legs joined by a bight, the two legs being flexible as the module is rotated into a slot in the insulative housing. The U-shaped latch includes a tab extending around an upwardly extending projection on the backwall of the housing to provide additional support to the latch. The latch thus provides means for holding the module securely within the housing after rotation to an upright position.

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.
