Description

Electronic card coupler

[technical field]

The present invention relates to a kind of electronic card coupler, relate in particular to a kind of electronic card coupler with trip mechanism.

[background technology]

The notebook computer development in recent years is rapid, and it can be equipped with the Expresscard connector usually, is used to realize the electric connection between notebook computer and the Expresscard card, so that carry out data storage and transmission.The Expresscard connector also can be provided with the trip mechanism that can easily the Expresscard card be withdrawed from usually, but the trip mechanism of present Expresscard connector does not have locking and blocking, so be easy under user mode, the Expresscard card directly be extracted, cause data to be lost by mistake.Therefore need between Expresscard card and Expresscard connector, device for fastening be set, and the device for fastening that is applied at present between the small intelligent card electronic card coupler corresponding with it can't apply to directly on the Expresscard connector.

The Taiwan patent announcement discloses a kind of electronic card coupler No. 507956, and it comprises the housing that contains plurality of terminals and is used for electronic cards is moved back the trip mechanism of card operation.This trip mechanism comprises a slide block, locking devicen, spring and locking device.Described slide block can slide on the electronic cards direction of insertion, and its side is provided with heart type groove; Spring is arranged in the middle of slide block and the housing, can provide to move back the required elastic force of card; Guide pins one end that is made of Metallic rod is fixed on the housing, and the other end can slide in heart type groove, and itself and described heart type groove constitute locking devicen, electronic cards and slide block can be resisted the elastic force of described spring and are fixed on a position latching.Described locking device comprises that the elastic arm and that an end is retained on the slide block is formed on the breach that is adjacent on the housing on slide block one sidewall, and described elastic arm has a contact jaw that is roughly " V " type, is used for and is formed on electronic cards lateral margin recess and cooperates.Be positioned at the slide block of initial preload position, the free terminal of its elastic arm aligns with the breach of housing sidewall, and electronic cards can allow elastic arm to extrinsic deflection when inserting; Be positioned at the slide block of position latching, the free terminal of described elastic arm and the breach of housing sidewall stagger and can't be to extrinsic deflections, so the contact site of this elastic arm promptly is maintained in the recess of described electronic cards, have just prevented that also electronic cards from being extracted by mistake in use.But this elastic arm needs to cause the complex structure of trip mechanism in the guide groove of solid and reliable embedding slide block, and manufacturing and assembly cost increase.

So, be necessary above-mentioned electronic card coupler is improved to solve the problems of the technologies described above.

[summary of the invention]

Main purpose of the present invention is to provide a kind of simple in structure and reliable electronic card coupler of pintle hook lock.

For achieving the above object, the present invention adopts following technical scheme: a kind of electronic card coupler, can accommodate an electronic cards that is provided with recess, and it comprises: contain the insulating body of plurality of terminals, be assembled in metal shell and trip mechanism on the insulating body.Described metal shell definition has one to be used to hold the receiving space of described electronic cards and insert port, and it also is provided with one and has the horizontal wall of through hole.Described trip mechanism comprises the pedestal that is fixed on the insulating body, can and be used to pin the locking devicen of sliding part along electronic cards is inserted and exit axis slides sheet metal, elastic parts.Sheet metal be provided with one be used for directly acting on described electronic cards move back a card arm and a holding part that cooperates with the recess of electronic cards, and definition has a preload position and a position latching.When sheet metal was positioned at preload position, the through hole that described holding part can pass metal shell left the recess of electronic cards, and when being positioned at position latching, described holding part is limited in the recess, can't remove.

Compared with prior art, the present invention has following beneficial effect: this electronic card coupler is simple in structure, can reduce manufacturing cost and simplify assembling procedure, and effective locking and blocking can be provided the electronic cards that is positioned at position latching.
