<P>PROBLEM TO BE SOLVED: To provide a push-push type connector with a return prevention mechanism added, such that a push-out state of a card is not impaired by slight vibration. <P>SOLUTION: The push-push type connector includes a slider, a return spring which energizes the slider in a push-out direction, a heart cam type pin guide groove 11 in a looped shape, and a guide pin which has one end supported rotatably, has a slide portion inserted into the other end of the pin guide groove 11, and is arranged to overlap the pin guide groove 11 and to face a slide-directional side of the slider. The pin guide groove 11 includes a press-down spring which has a forward-path guide groove portion 11A and a return-path guide groove portion 11B, made different in position relation to the left and right, on both sides of a push-out stop position, and an ascendant slope portion 20 for moderation in such a shape that a groove bottom surface is swelled integrally at a start end portion of the forward-path guide groove portion, and impairs resistance on upward operation of the slide portion when the slide portion of a guide pin passes the position of the ascendant slope portion of moderation, and thereby adds movement resistance on the slide portion of the guide pin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
