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 electronic cards and circuit board electric connection.

[background technology]

In the industry cycle general miniature electric memory card, as SD card (Secure Digital Card) is to adopt electronic card coupler that electronic cards and circuit board are electrically connected, because electronic cards and electronic card coupler often carry out plug-in card or move back the action of card, and existing electronic card coupler is that electronic cards is directly cooperated with the insulating body plug of electronic card coupler, because electronic cards and insulating body are made by insulating material, and the coefficient of friction of insulating material is higher relatively, so, increase the abrasion between described electronic cards and the electronic card coupler.Announce No. 2571023 and No. the 200420054525.5th, Chinese utility application as Chinese utility model patent, it has all disclosed the existing electronic card coupler with above-mentioned feature.

Announcing No. 2571023 with Chinese utility model patent is example, see also shown in Figure 8, a kind of electronic card coupler, it comprises: insulating body 3, some be contained in the conducting terminal 5 in the insulating body 3 and be covered in form the shielding casing 2 that can accommodate the receiving space 34 of electronic cards on the insulating body 3.The two

side

32,33 that described insulating body 3 has rear wall 31 and extend side by side from rear wall 31 two ends all is concaved with a pair of guide channel 323,333 on this sidewall opposite flank, this guide channel 323,333 can be guided electronic cards and be inserted in the receiving space 34.Because described electronic cards and insulating body 3 are made by insulating material, so, increased the friction between electronic cards and the insulating body relatively, when the plug number of times is too much, described electronic cards and insulating body all have certain wearing and tearing, and the quality of fit between electronic cards and the insulating body is also decreased; When plug-in card is incorrect, also may damage the two side, so, to all being under some influence in useful life of electronic cards or electronic card coupler.

Therefore, necessary existing electric connector is improved, to overcome defective of the prior art.

[summary of the invention]

Technical problem to be solved by this invention is to provide a kind of electronic card coupler of wearing and tearing when reducing electronic cards and electronic card coupler plug.

Another technical problem to be solved by this invention do can prevent when plug-in card incorrect and cause the electronic card coupler of electronic card coupler breakage.

For addressing the above problem, electronic card coupler of the present invention adopts following technical scheme: a kind of electronic card coupler, comprise: insulating body, the first side wall and second sidewall that it has base portion, extends forward from the base portion two ends and be oppositely arranged, this first, second sidewall end has opposed facing side; Shielding casing, be cover cap on described insulating body, and the common receiving space that can accommodate electronic cards that forms of described shielding casing and above-mentioned first, second sidewall; Wherein, the contiguous the first side wall of described shielding casing and the second sidewall end are respectively equipped with the slide guide face to the receiving space inner bending, and described slide guide face is between two sides and can guide electronic cards and insert in the receiving space.

Compared with prior art; electronic card coupler of the present invention has following beneficial effect: the slide guide face guiding electronic cards by described shielding casing is inserted in the receiving space; cooperate with the plug of shielding casing slide guide by electronic cards; can reduce the friction between electronic cards and the electronic card coupler and reduce wear; and can protect first, second sidewall not to be damaged; thereby; electronic card coupler of the present invention was compared with the useful life of existing electronic card coupler, can prolong the useful life of electronic cards and electronic card coupler relatively.
