A connector block molded of glass-filled thermo-plastic includes an integral gate extending along the ends of a row of cavities. The gate is connected to the block by a hinge portion having opposed resin rich surface layers and a rigid glass fiber-resin composite between the layers. Upon movement of the gate toward a position where it closes the adjacent ends of the cavities, one resin layer and the composite in the hinged portion break permitting retention of the gate about the remaining flexible layer to close the ends of the cavities.

A zero force edge connector block includes a plurality of terminals for engaging pads on a circuit board, an elongate cam bar extending along the terminals, and a drive for shifting the cam bar along the terminals so that the cam bar engages ramp surfaces in the block and is raised diagonally to engage the terminals and move the terminals to a retracted position. After the board has been positioned in the block, the cam bar is moved back to its initial position, thereby freeing the terminals to engage contact pads on the board.

A header is provided for mounting on a circuit board comprising a block having a plurality of circuit board pins mounted therein and a generally rectangular unitary housing. The unitary housing and block have a face for mounting on a surface of a circuit board. The face having a cavity at each end of the block for receiving a pair of latch members. Each cavity having a common wall with each end of the block, a recessed surface spaced from the face, and a wall spaced from the common wall having a rectangular channel therein. Also provided is a latch member for insertion in each cavity at each end of the block. Each latch member including a base having a substantially rectangular member protruding from one side of the base, an elongated tapered latch arm extending from the base, a latch surface on the free end of the latch arm, and a latch release extending from the latch opposite the latch surface.
