Patent ID: 7575453

Claim:
A locking and ejecting apparatus for holding an electronic module having at least one connector, comprising: a carriage defining an entrance for allowing entrance of the electronic module therethrough; a sliding bracket slid in the carriage, a mating connector attached to the sliding bracket configured for mating with said at least one connector of the electronic module; at least one resilient member being placed between the carriage and the sliding bracket configured for urging the sliding bracket sliding relative to the carriage; a triggering portion formed on one of the carriage and the sliding bracket; and a push-push switch attached to the other of the carriage and the sliding bracket, two actuated retaining pieces being formed on the push-push switch, a trigger set between the retaining pieces; wherein when the electronic module is slid into the carriage via the entrance thereof and the connector of the electronic module is mated with the mating connector, the sliding bracket is pushed inward relative to the carriage and the resilient member is deformed, the trigger of the push-push switch is triggered by pressing of the triggering portion, the retaining pieces of the push-push switch are actuated to hold the triggering portion, the sliding bracket is locked in the carriage and the electronic module is received in the carriage; when the trigger of the push-push switch is triggered by pressing of the triggering portion again, the retaining pieces of the push-push switch are actuated to release the triggering portion, the sliding bracket and the electronic module are pushed by a restoring force of said at least one resilient member, thus the electronic module is at least partially ejected from the carriage and the connector of the electronic module is departed from the mating connector.
