<P>PROBLEM TO BE SOLVED: To provide a simple configuration capable of taking states of both half lock and full lock without impairing operability of a push-push system. <P>SOLUTION: An ejection plate 16 has a pressing part 16a, an engaging part 16c and a spring part 16d and is switchable in two positions with a heart cam 19. In a state that a card and a connector are electrically connected, the ejection plate 16 is located in a second position, an engaging part 16c engages with a notch provided in the card, release of engagement is prevented with a guide wall 24, and the card can not be pulled out even if a strong drawing force is applied (full lock). When the ejection plate 16 moves from the second to a first position with a tension spring 17, the card is pushed out by the pressing part 16a. Although the engaging part 16c engages with the notch of the card even in the first position, release of engagement is allowed by the wall part 24, and the card can be pulled out by the elastic deformation of the spring parts 16d (half lock). <P>COPYRIGHT: (C)2007,JPO&INPIT |
