Description

Electronic card coupler

Technical field

The utility model relates to a kind of electronic card coupler, refers to a kind of trip mechanism that has especially, can prevent that electronic cards from moving back the electronic card coupler that card moment flies out.

Background technology

Because light, thin, short, the little characteristic of electronic cards, therefore be used on the electronic installations such as digital camera, individual action digital assistants (PDA) or mobile computer widely, can be used as the usefulness that expands memory space, with the problem of effective solution traditional magnetic disk (disk) insufficient space.

Electronic cards is a kind of portable instrument, can be inserted easily and be withdrawed from by an electronic card coupler, and known electronic card coupler mostly is provided with a trip mechanism, uses the operation that makes things convenient for plug-in card, moves back card.As letters patent number: patent cases such as M269612, M278120, M284048 are to disclose multiple electronic card coupler with trip mechanism is arranged.

The trip mechanism of above-mentioned electronic card coupler all is provided with an engaging body (or claiming button to hold sheet, fastening bar), when electronic cards is inserted in the plug-in card space of electronic card coupler, can utilize the buckle end of this engaging body to be snapped in the corresponding breach of this electronic cards one side, make this electronic cards be seen through this engaging body and be fixed on the trip mechanism.

But, because this trip mechanism is a strength of utilizing spring to provide to move back card, the elasticity strength of spring is quite big, therefore move back the moment of card in electronic cards, this electronic cards breaks away from the buckle end that engages body easily, makes that electronic cards is launched to fly out, and causes the phenomenon that flies card, and then make and cause electronic cards to damage, lose or get to user's safety problem in the electronic cards ground of dropping.

Moreover; general electronic cards is when being inserted in the plug-in card space of electronic card coupler; usually the gapped existence of meeting between electronic cards two sides and the plug-in card space two side inwalls; make electronic cards be easy to generate deflection, adding this engaging body is to have elasticity, easily outwards swing; and its buckle end mostly is bent into arc or is provided with chamfering; more can make the buckle end of engaging body be difficult to make electronic cards in the moment of moving back card in certain breach that is snapped in electronic cards that the phenomenon that flies card is even more serious.

Summary of the invention

Main purpose of the present utility model, being to provide a kind of electronic card coupler, moves back moment of card in electronic cards, can effectively prevent to fly the phenomenon of card.

In order to reach above-mentioned purpose, the utility model provides a kind of electronic card coupler, comprising: an insulating body, and it is provided with a plug-in card space, and this insulating body is provided with several terminal grooves; Several terminals, it is installed on these terminal grooves; One trip mechanism, it is arranged at this plug-in card space one side, and this trip mechanism has a sliding shoe, and this sliding shoe is being arranged on this insulating body of sliding, and this sliding shoe one end has one toward the outstanding hook part of this plug-in card direction in space; And a shielding casing, it is covered on this insulating body, and this shielding casing has a shell fragment, and this shell fragment is the opposite side of being located at this shielding casing and being positioned at this trip mechanism, and this shell fragment forms a supporting part, and this supporting part stretches in this plug-in card space.

The utlity model has following useful effect: the utility model drives electronic cards at sliding shoe and moves back in the process of card, the supporting part of this shell fragment can be resisted against this electronic cards one side, electronic cards can not moved toward the direction in gap, electronic cards can be promoted to move toward the direction of sliding shoe by the supporting part of shell fragment, make in the breach that is snapped in electronic cards that the hook part of this sliding shoe can be firm, has preferable buckle effect, therefore move back the moment of card in electronic cards, this electronic cards can not break away from the hook part of sliding shoe, make electronic cards can not launched and fly out, effectively prevent to fly the phenomenon of card.
