Card edge connector with detecting contacts

摘要

A card edge connector for mating with a memory card includes a longitudinal insulative housing, a plurality of contact terminals received in the insulative housing, at least one pair of ejectors and two detect pins having spring and being moveable relatively each other. The ejectors are moveable between locking station and release station. One of the detect pins defines an engaging portion protruding into an inserting slot of the insulative housing for engaging with a bottom edge of the memory card and pushing the detect pins to connect disconnect with each other. Furthermore LED is combined with the detect pins for testing if the memory card is inserted into the connector.

1. A card edge connector for engaging with a memory card, comprising:
a longitudinal insulative housing includes an inserting slot for receiving the memory card and a receiving opening communicating with the inserting slot; a plurality of contacts retained in the insulative housing, and each of the contacts having a mating portion extending into the inserting slot for contacting with the memory card; and at least one pair of detecting contacts comprising a first detecting pin and a second detecting pin received and retained in a receiving slot formed in the insulative housing; wherein the second detecting pin comprises a spring engaging arm having an engaging portion protruding into the inserting slot and adapted to be pushed downwards by a bottom edge of the memory card, and a second contact portion located on a distal end of the spring engaging arm along the engaging portion and at a different level with regard to the engaging portion; insertion of the memory card into the inserting slot makes the contact portion engaged with or disengage from the first detecting pin; wherein the first detecting pin comprises a bending portion presenting as a reverse U shape and a first contact portion disposed on distal end of the bending portion engaging with the second contact portion of the second detecting pin; wherein the receiving slot includes a positioning groove formed in the insulative housing for receiving the bending portion, and a stopper portion positioned against the bending portion of the first detecting pin.
