Embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model:

Fig. 1 is the three-dimensional exploded view of the utility model one preferred embodiment, and together with reference to Fig. 2-shown in Figure 5, can be clear that from figure, the utility model mainly by: housing 1, organize conducting terminal 2 and a casket body 3 is formed more; Wherein, housing 1 present embodiment is that the lid 10 of insulating base frame and metal material constitutes, described pedestal is provided with a rear wall, left and right sides sidewall and lower wall, can be interlocked with the lid 10 of a metal material with the slot 11 that forms ccontaining storage card A, the shell fragment 13 that one metal material is arranged in housing 1 opening part front-end configuration, this shell fragment 13 is by open front projection gradually backward, described housing 1 all sides are provided with many group conducting terminals 2 and card detection terminal 20, slot 11 sides configuration trip mechanism 12, this trip mechanism 12 includes slide block 121, spring 122 and scratching part 123;

Many group conducting terminals 2, by the terminal more than at least one row and card detection terminal 20 are formed, terminal ends makes progress the elasticity perk and forms a contact site 21 and be electrically connected to do with the contact (I/O) of storage card A;

Casket body 3, roughly rectangular, its big low profile just can be placed in the slot 11 of housing 1, have in the casket body 3 can ccontaining storage card A casket groove 31, the casket groove 31 of present embodiment and the slot 11 of housing 1 are towards equidirectional setting, and casket body 3 terminal at least one sides have projection 32, with the shell fragment 13 of corresponding housing 1, provide hollow-out parts 33 in the middle of the casket body 3, can make the contact site 21 of the many groups conducting terminal 2 that is disposed on the housing 1 pass hollow-out parts 33 and protrude out to casket groove 31 interior (as shown in Figure 5).

During assembling, at first will organize conducting terminal 2 more and be disposed at housing 1 predetermined position, it is inner and be disposed at housing 1 all sides to make many group conducting terminals 2 and card detection terminal 20 stretch into housing 1, and makes shell fragment 13 place housing 1 leading edge, again configuration one lid 10 on housing 1, then casket body 3 directly is inserted in the slot 11 interior (as shown in Figure 2) of housing 1, promptly finish combination, because shell fragment 13 is by opening projections in the slot 11, therefore can be after assemble case 1, just transplanting casket body 3, can simplify the operation in the assembling.

During use, 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 electrical connection with the conducting terminal 2 of contact housing 1 correspondence, in pushing when moving back card, because the configuration of casket body 3 terminal projections 32, can collude and hold the shell fragment 13 that housing 1 opening inner edge is protruded out, break away from (as shown in Figure 4) fully from housing 1 to prevent casket body 3 and the storage card A that is loaded in it.

In addition, 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 many groups conducting terminal 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, plant the structure use so that other to be provided.

Fig. 6 is the structural representation of another preferred embodiment of the utility model, and wherein said shell fragment 13 is directly gone out by the lid 10 of metal material and be one-body molded, and is all identical with a last embodiment as for other structures, so repeat no more.

Therefore no matter in sum, card connector of the present utility model can prevent that the storage card bullet from flying out when moving back card, on the function, all make progress than known configurations in the assembling.

The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
