Description

The locking device of electronic card coupler

Technical field

The utility model relates to the locking device of electronic card coupler, especially finger is a kind of is provided with locking device in the connector side, when being beneficial to electronic cards insertion connector, locking device can be embedded in the connector electronic cards is stable, and electricity connects reliably, and reliable and stable with docking of connector and the difficult skew of electronic cards is rocked.

Background technology

Computer technology is just grown up with the different speed development of day new film now, and it is light that computer tends to day by day, thin, short, little, calculation function reaches fireballing direction by force to be developed, and be usually used in expanding computer, the memory card of electronic dictionary etc., the networking card, modem, scsi device is (as the high power capacity hard disc, scanner) etc. electronic cards is its main means, and the canonical form that electronic cards is embedded on the computer is PCMCIA, as PCMCIA to SCSI, PCMCIA to IDE etc., all can make the notes computer can be used in the multiple interfare device of PC, and in major part notes computer, all has the ability of supporting Plug and Play, even support to start shooting again and just can directly use heat grafting (Hot Plug) function, and MMC (Multi Media Card) is roughly still arranged at present on the market, CF (Compact Flash Card), SM (Smart Media Card), MS (Memory Stick), SD specifications such as (Secure Digital Memory Card) can be for apolegamy; Yet, above-mentionedly commonly use design, owing to must electronic cards be released by rotatable lamella, so the whole height of connector and length certainly will will increase, and for the memory card of thinner thickness, too high connector is easy to rock and locate built on the sand after can causing electronic cards to be inserted, if the connector whole height is reduced, then the volume of integrated member must correspondingly diminish, the corresponding increase of accuracy and be difficult for to make, and can increase assembling with cost of processing and the difficulty when assembling.

But, present employed electronic card coupler, all be to utilize the direct promotion of a push rod to be equipped with the rotatable lamella of the plug socket top of plural terminals mostly, make this rotatable lamella present an anglec of rotation, and then make the electronic cards that butts up against plug socket separate (as shown in Figure 6), yet, this kind mode is when electronic cards and plug socket are mated condition, the press-side of its push rod just can be exposed to the computer slot outside, so the situation that mistake is pressed very easily takes place, and electronic cards in causing operating and plug socket generation disengaging, and then the data that computer takes place in deadlock or the running is vanished from sight, and sustain a loss.

Thereby the global design of the above-mentioned connector of commonly using still has many shortcomings, the necessity that still remains further improvement, and above-mentioned shortcoming just becomes the direction place of being engaged in this journey improvement that the dealer desires most ardently.

So I am because above-mentioned deficiency and the shortcoming of commonly using connector, be to collect related data, through assessing in many ways and considering, the side is to be engaged in the many years of experience of the industry, by continuous design, modification, the beginning is designed the technical scheme of the easy and simple to handle and constitutionally stable electric connector of this kind.

The utility model content

Main purpose of the present utility model is to provide a kind of locking device of electronic card coupler, and the side of its connector is provided with locking device, so that with the firm inlay card of the electronic cards of inserting location, make electronic cards be difficult for producing and rock or be offset.

Secondary objective of the present utility model is to provide a kind of locking device of electronic card coupler, and its locking device is hubbed on the slideway of connector side, and slippage thereon, can the locking device pushing tow be returned original position by the flexible member of locking device front end face.

A purpose more of the present utility model, be to provide a kind of locking device of electronic card coupler, its locking device side is provided with clamping piece, this clamping piece can slippage on the slide rail of slideway side, when clamping piece slides onto the groove meeting downbending of track in groove, if the clamping piece slippage in orbit, then can convexedly stretch in slippage on the track.

For reaching above-mentioned purpose, the locking device of a kind of electronic card coupler of the present utility model, this connector is made up of pedestal, locking device and flexible member, and can push by the secondary of electronic cards, make locking device on pedestal, form a circulating slippage action, it is characterized in that:

This pedestal insertion end one side is provided with slideway, and the inboard is provided with the slide rail of protrusion, and this slide rail is provided with groove, and is equipped with plural terminals in the side away from insertion end;

This locking device is embedded on the slideway of pedestal, and its inboard is provided with depressed part, and this depressed part the place ahead is provided with ejection face and is through to the chute of locking device front end face, and this chute extends the elasticity clamping piece of tool protuberance backward; This flexible member is between base slideway front end and locking device front end face; The clamping piece of its locking device can be at least a with track and cooperate, and promotes locking device when making electronic cards insert connector and is a slippage, and make the clamping piece inlay card be a location in the blocking hole of electronic cards.Wherein:

The clamping piece of described locking device can be at least a with track and cooperate, refer to that clamping piece is upspring in orbit or downbending at the groove of track.

Described locking device is provided with ejection face at the clamping piece place of the chute other end, and this ejection face is fitted with the interface of electronic cards.

Described slideway front end is provided with locating part, and this locating part is set in an end of flexible member.

Described ejection face is the heeling condition that is inside.

Described pedestal is provided with the flexible guide rod of tool in the side in addition of insertion end, and locking device is provided with the circulation guide groove that can supply guide rod portion's slippage within it or location.

Because the locking device of the utility model connector can be with the electronic cards displacement, and electronic cards is equipped in the connector, can make that electronic cards is stable to be fastened in the connector, and reliable electricity is connected to each respective terminal of connector, and is difficult for rocking or being offset; And secondary is when pushing electronic cards, and this electronic cards will eject automatically.
