Electronic card connector

This creation is about an electronic card connector.

Taiwan Patent No. 431655 discloses a connector comprising an insulative housing and a plurality of contact terminals. The front side of the insulating housing is concavely formed with a slot. A wall with a terminal slot is formed over the slot, wherein each terminal slot is used to position a contact terminal therein.

Each of the contact terminals is formed with a first elastic arm that is bent downward, and further extends to form a convex contact portion and an end portion that is folded upward. When the connector accepts a complementary mating component, the contact portion will make electrical contact with the corresponding conductive strip on the complementary mating component and be displaced by the push. The contact terminal includes a second resilient arm formed by extending the end of the first resilient arm toward the wall of the terminal slot of the wall. The movable distance between the end of the second resilient arm and the groove wall is smaller than the distance that the contact portion can actually displace after the complementary docking element is inserted, so that when the complementary docking element is inserted, the end of the second elastic arm can abut the groove The wall creates another elastic resistance for bringing the contacts into close contact with the conductive sheets.

The contact terminal is formed by the second elastic arm abutting against the groove wall on the insulating housing to generate another elastic resistance. During the long-term use of the connector, the plastic groove wall is scratched by the contact terminals, so that the plastic groove wall is easily damaged and recessed, which causes another elastic resistance to become smaller and smaller, eventually becoming a failure.
