All be provided with in the existing card connector and push retreat-card device, as No. the 6508402nd, United States Patent (USP), No. the 095210770th, novel patent application of TaiWan, China etc., these connectors have comprised the housing with grafting card mostly, be provided with plurality of conductive terminals in the shell, and trip mechanism in order to storage card is withdrawed from the housing, described trip mechanism includes slide block, spring and scratching part, card can slide and plant to housing with slide block, and hold positioning sliding block in certain position to collude by scratching part, when moving back card, elastic-restoring force by spring is released slide block, simultaneously card is withdrawed from synchronously, but At time of eject, card is because of effect of inertia and any block function is not arranged, thereby the normal bullet plug-in card space that flies out, to such an extent as to fall to ground.

Because the electric consumers function becomes to increasing day by day, the Extended RAM capacity has been necessary, for making in getting over complicated circuit layout and functional increase day by day, but product is tending towards mini mobile phone, and is also very urgent for the ease of use after the overall volume downsizing that improves inner spare part.

Therefore, design a simple in structurely, easy to operate, and the card connector that accords with the demands of the market is the problem that the utility model institute desire solves.

The utility model content

Main purpose of the present utility model is to provide a kind of card connector, and in the time of can avoiding storage card to move back card, bullet flies out.

Another purpose of the present utility model provides a kind of card connector, makes card connector simple in structure, to meet the demand that the consumer uses.

For reaching above-mentioned purpose, the utility model provides a kind of card connector, mainly constitute by housing and casket body, the housing front end forms an opening, be provided with some groups of conducting terminals in the housing, contact the contact of the storage card bottom surface that is suitable for correspondence, have in described its casket of casket body can ccontaining storage card the casket groove, this storage card can and be inserted in the housing with slippage before and after the casket body, be electrically connect with some groups of conducting terminals of contact housing correspondence, terminal one of casket body has projection with upper side edge, can fasten, collude and hold inner walls, when moving back card to prevent to push, the casket body breaks away from fully from housing.

In the utility model, be provided with trip mechanism between housing and casket groove, described trip mechanism includes slide block, spring and scratching part.

In the utility model, casket groove on the casket body and relative configuration of slot on the housing.

In the utility model, casket groove on the casket body and the slot on the housing dispose in the same way.

In the utility model, provide hollow-out parts on the casket body, pass hollow-out parts and stretch in the casket groove for being disposed at some groups of conducting terminals on the housing.

According to such scheme, the utility model has obtained following good effect by suitable and practical spare part:

One, can reduce storage card that the careless mistake because of the user produces damages and loses probability.

Two, reduce the space occupied area, the sub-product of can powering is convenient to tend to mini design.

Three, being convenient to the consumer uses.

Embodiment

As for detailed structure of the present utility model, use effect, application principle,, can obtain cognitive completely with reference to following accompanying drawing and illustration:

Fig. 1 is the three-dimensional exploded view of the utility model one preferred embodiment, and together with reference to shown in other each figure, can be clear that from figure, and the utility model mainly is made up of housing 1, some groups of conducting terminals 2 and a casket body 3; Wherein, in the present embodiment, housing 1 is the plastics ejection formation, be provided with a rear wall, left and right sides sidewall and lower wall, can be interlocked with the slot 11 that forms ccontaining storage card A with a lid 10, protrude out in housing 1 opening part front end and be provided with stop section 13, described housing 1 all sides are provided with described some groups of conducting terminals 2 and card detecting terminal 20, slot 11 sides configuration trip mechanism 12, this trip mechanism 12 includes slide block 121, spring 122 and scratching part 123;

Some groups of conducting terminals 2 are made up of the terminal more than at least one row, and terminal ends makes progress the elasticity perk and forms a contact site 21 to make electrically connect with the contact (I/O) of storage card A;

Casket body 3 is roughly rectangular, its big low profile just can be inserted in the slot 11 of housing 1, have in the casket body 3 can ccontaining storage card A casket groove 31, as shown in Figure 2, the casket groove 31 of present embodiment and the slot 11 of housing 1 be towards equidirectional setting, and terminal one of casket body 3 has projection 32 with upper side edge, with the stop section 13 of corresponding housing 1, provide hollow-out parts 33 in the middle of the casket body 3, can make the contact site 21 that is disposed at the some groups of conducting terminals 2 on the housing 1 pass hollow-out parts 33 and protrude out in the casket groove 31.

During assembling, as shown in Figure 3, at first some groups of conducting terminals 2 are disposed at housing 1 predetermined position, make some groups of conducting terminals 2 and card detecting terminal 20 stretch into housing 1 inside and be disposed at housing 1 all sides, then casket body 3 is placed in the slot 11 of housing 1, on housing 1, dispose lid 10 at last again, promptly finish combination.

During use, as shown in Figure 4, this storage card A can and be inserted in the slot 11 of housing 1 with the 3 front and back slippages of casket body, be electrically connect with the terminal of contact housing 1 correspondence, push when moving back card, because the configuration of casket body 3 terminal projections 32 can be colluded and be held the stop section 13 that housing 1 opening inner edge is protruded out, break away from fully from housing 1 to prevent casket body 3 and the storage card A that is loaded in it.

In addition, as shown in Figure 5, on the casket body 3 in order to the casket groove 31 that loads storage card A can with the slot 11 relative configurations of housing 1, make the contact site 21 of the some groups of conducting terminals 2 on the housing 1 not need to protrude out in the casket groove 31 by the hollow-out parts on the casket body 3 33, so that being provided, another kind of structure uses, all identical as for other structure with a last embodiment, so repeat no more.

In sum, card connector of the present utility model can prevent that the storage card bullet from flying out when moving back card, no matter all is being progressive to some extent than existing structure on the function, in the assembling therefore.

The above is preferred embodiment of the present utility model only, is not to be used for limiting protection range of the present utility model, and all equalizations of doing according to the utility model change and modify, and are all by the scope of the utility model claim and contain.
