[technical field]

The relevant a kind of electronic card coupler of the utility model relates in particular to a kind of electronic card coupler with trip mechanism.

[background technology]

Along with popularizing of digital camera, mobile phone, PDA, the use of electronic cards is also more and more, and in the electronic cards use or when utilizing trip mechanism to move back card, electronic cards is impacted easily and in electronic card coupler, flown out.The prior art relevant with the utility model can be consulted Chinese invention patent CN100555766C number of on October 28th, 2009 bulletin; Disclosed a kind of electronic card coupler in order to the grafting electronic cards; It comprises: insulating body, be contained in the conducting terminal in the insulating body and be located at the trip mechanism of insulating body one side, insulating body is provided with the slot of accommodating electronic cards and is exposed to the insertion mouth in the outside from slot forward.The axle that electronic card coupler also comprises the support that is installed in insulating body one side, extend from support to the inside, the metal confinement piece that can slide at open position or locked position with respect to insulating body along axle and be set in the elastomeric element on the axle, confinement block shield portions when initial condition insert mouthful.When electronic cards is inserted receiving space, manually promote confinement block laterally, confinement block compresses elastomeric element laterally; After the another hand inserts slot with electronic cards then; Unclamp confinement block, elastomeric element pushes original position with confinement block and is pressed on the electronic cards front end, moves forward with the restriction electronic cards.After needing manually to promote confinement block laterally during card taking and moving, manually press, the another hand just can take out the electronic cards in the slot, need both hands to operate, and uses inconvenient.

Therefore, to above-mentioned technical problem, be necessary to provide a kind of structure improved electronic card coupler that has, to overcome above-mentioned defective.

[utility model content]

The purpose of the utility model is to provide a kind of electronic card coupler easy to use.

For reaching above-mentioned purpose; The utility model adopts following technical scheme: a kind of electronic card coupler; It comprises: insulating body, conducting terminal and be arranged at the trip mechanism on the insulating body, and said insulating body is provided with the slot of accommodating electronic cards, and the slot front end is provided with one and inserts mouthful; Said trip mechanism comprises the slide block be arranged on the insulating body and slide along fore-and-aft direction of sliding, press on spring and the guide rod of positioning sliding block and insulating body relative position between insulating body and the slide block; Said trip mechanism comprises that also the confinement block of being located on the slide block reaches the elastic component between slide block and confinement block, and confinement block can move between first, second position, covers when confinement block is positioned at primary importance to insert a mouthful front end; Move forward with the restriction electronic cards; When confinement block is positioned at the second place, inserts mouth and be exposed to the outside fully forward, elastic component pulls back confinement block and arbitrarily moves between first, second position to avoid confinement block.
