Along with the fast development of consumption electronic products such as mobile phone, digital camera, especially under the prerequisite that the function of various electronic products is rapidly expanded, the memory capacity of these equipment itself can not satisfy the demands of consumers.Therefore, electron production merchant adds electronic card coupler and connects outside storage card medium in electronic equipment, to expand the memory capacity of electronic equipment.So the electronic card coupler that is exclusively used in the various electronic cards of winding is widely used in the various electronic equipments.Simultaneously, will take out electronic cards is in electronic card coupler for convenience, many electronic card couplers have been set up trip mechanism.
The electronic card coupler that has trip mechanism in the prior art please refer to shown in the novel patent of TaiWan, China M354242 number, and it includes an insulating body, somely is contained in the conducting terminal of insulating body and is mounted on trip mechanism on the insulating body.Insulating body comprises body that conducting terminal is installed, extend upward the sidewall of formation from the body both sides and extend upward the aft bulkhead of formation from the body rear end; Described trip mechanism by one move back card and one with move back the push rod that card is connected and form, wherein, described push rod is immobilizated in insulating body one side, it can move back card along the fore-and-aft direction pushing tow that moves; The described card that moves back is formed by a sheet metal punching press, dash thereon to establish to form a circular hole, and the insulating body aft bulkhead upwards protrudes out and is formed with the rotating shaft that cooperates with this circular hole, thereby the described card that moves back can rotate realization along this rotating shaft and push away and move back card.
But the rotation fitted shaft of the electronic card coupler trip mechanism of prior art is positioned at the top of insulating body aft bulkhead, causes the electronic card coupler whole height to increase thus, is unfavorable for the slimming development trend of electronic card coupler.Simultaneously, because of trip mechanism is provided with insulating body one side, the active force when it moves back card acts on electronic cards one side, and electronic cards is subjected to force unbalance and causes moving back that electronic cards deflects easily in the card process thus, thereby influences withdrawing from smoothly of electronic cards.
In view of above problem, be necessary to provide a kind of improved electronic card coupler in fact, to address the above problem.
