Abstract:
1. An electrical connector comprising: a housing of a quadrangular shape in which a printed substrate of a rectangular shape including a pair of locking holes at both wings of a connection end portion is inserted and extracted; a pair of headers having base end portions that are disposed at both wings of the housing, and tip portions that extend in parallel; a pair of crank levers that are held to freely swing at the base end portion of the pair of the headers; a pair of ejectors that is held at a pair of the headers to freely advance and retract by a swinging movement of a pair of the crank levers being converted to translatory movement parallel with an inserting and extracting direction of the printed substrate; and a pair of clip arms that projects from the pair of ejectors through the pair of headers, and extends toward each other in a direction perpendicular to an inserting and extracting direction of the printed substrate, wherein the pair of headers includes a pair of first grooves facing each other that extends from the tip portions toward the base end portions and guides both end edges of the printed substrate, a pair of second grooves that is in communication with the first grooves and is provided at a width slightly narrower than a width of both side faces of the pair of clip arms, and a pair of third grooves that is in communication with the second grooves and abuts both side faces of the pair of clip arms, wherein the pair of crank levers includes a first swing arm that can abut both sides of an end face of the connection end portion and a second swing arm that abuts a bottom face of the pair of ejectors, wherein the clip arm includes a gap which opens from the base end portion toward the tip portion and through which the printed substrate can pass, and a pair of projections that is provided at a tip portion of the clip arm and projects to the gap toward each other so as to be capable of fitting the locking hole, and wherein, when the printed substrate is inserted into the housing, the pair of crank levers is caused to pivot so that the pair of ejectors is caused to move in a direction opposite to an inserting direction of the printed substrate and the pair of clip arms is caused to move from the pair of third grooves to the pair of second grooves to fit the pair of locking holes so as to sandwich both faces of the printed substrate.
