Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, refers to a kind of electronic card coupler with trip mechanism especially.

[background technology]

Present most of electronic card coupler all is equiped with retreat-card device, moves back the card operation to make things convenient for the user to finish easily to push away, and in the trip mechanism of numerous kinds, PUSH-PUSH type trip mechanism is easy and simple to handle and conserve space and obtain using more widely with it.And common PUSH-PUSH type trip mechanism is for pushing the trip mechanism that electronic cards is moved back card by secondary.

This kind pushes trip mechanism that electronic cards realizes moving back card by secondary because uncontrollable elasticity setback force when moving back card; through regular meeting electronic cards is flown out; the card phenomenon appears flying; traditional solution is grab of installing on the sliding shoe of trip mechanism, catches on the electronic cards that retreats fast when moving back card.It can prevent to fly the generation of card phenomenon, but its retain strength is big and relate to for doing something in disregard of obstacles, and damages electronic cards easily and causes the puzzlement that is difficult to take off electronic cards, influences user's use.And it is just made a response to the card that flies out at a high speed, can't really reach the effect of slowing down trip mechanism slide unit setback force and astern speed, push away when moving back card motion when doing too much, the trip mechanism that moves back card under the elastic force effect at a high speed will impact to electronic card coupler integral body, and then make connection between the mechanism components loosening etc., influenced the whole switching performance of electronic card coupler to a certain extent, thereby to causing certain influence the useful life of electronic card coupler.

For fear of the problems referred to above, the utility model proposes a kind of new electronic card coupler to compensate its defect.

[utility model content]

The technical problems to be solved in the utility model provides a kind of electronic card coupler that can effectively cushion trip mechanism elasticity setback force.

For solving the problems of the technologies described above, the utility model provides a kind of electronic card coupler, it comprises insulating base, be covered on the insulating base and and constitute the shielding casing of accommodating the electronic cards receiving space jointly with insulating base, be contained in plurality of conductive terminals and trip mechanism in the insulating base, wherein, insulating base comprises main part and is positioned at the hold-down arm of main part one side, trip mechanism is installed on the hold-down arm of insulating base, it comprises that one can be with respect to the slide unit of insulating base motion, one flexible member and an alternative backstay of locating slide unit and insulating base relative position that provides slide unit to reset, offer the buffering conduit in the wherein said hold-down arm, one link gear part movably is contained on the slide unit, and part is accommodated and run in the buffering conduit.

Be compared to prior art, electronic card coupler of the present utility model has following effect: it runs in the buffering conduit of insulating base by link gear, when moving back card fast, the buffering conduit will interfere link gear to slow down vertical speed of service of link gear, force link gear that slide unit is produced resistance, slow down the purpose that the trip mechanism setback force prevents to fly the card generation thereby reach.
