Abstract
Abstract A connector (20) for electrically connecting the conductor (24) of a wire (22) to circuitry on a circuit board (14) within an electrical unit (10) is disclosed. The connector includes an insulating housing (32) with two side by side cavities (60) separated by a wall (62), each cavity containing an electrical contact (34). A pair of conductor openings (72) are formed in the front end (30) of the housing side by side so that each opening is in alignment with one of the cavities and in communication therewith. The conductors (24) are terminated to the contacts (34) by pushing them through the openings and into locking engagement with their respective contacts. A second opening (78) is provided to receive a tool (94) for releasing the contacts from locking engagement. A mounting device (82) is provided to secure the connector to the circuit board (14). Additionally, flanges (88) are provided on the housing to abuttingly engage the outer case (12) to prevent damage to the unit should the wires be inadvertently pulled away from the unit.
