[embodiment]

Refer to shown in Fig. 1, disclose a kind of electronic card coupler 100 of the present utility model, this electronic card coupler 100 can be soldered on circuit board and in order to grafting electronic cards (not shown).In the present embodiment, this electronic card coupler 100 comprises insulating body 10, is retained on the several conducting terminals 20 on insulating body 10 and is covered in and cover shell 30 outside insulating body 10.

Refer to shown in Fig. 2 and Fig. 3, the pair of sidewalls 12 that described insulating body 10 has diapire 11 and upwards protrudes out from diapire 11 two ends.This diapire 11 and shielding casing 30 are formed with the receiving space 300 (shown in please refer to the drawing 1) of inserting electronic cards along plug orientation jointly, certainly also can be regarded as described diapire 11, sidewall 12 and shielding casing 30 and jointly form this receiving space 300, thus, above-mentioned sidewall 12 is positioned at the both end sides (i.e. left and right directions) of receiving space 300.The outside of each sidewall 12 is provided with some projections 13 and at least one sidewall is provided with the inclination slider guide 14 protruding into and receive in space, what above-mentioned shielding casing 30 had the roof 31 relative with the diapire 11 of insulating body 10 and connected roof 31 both end sides bends sidewall 32 a pair, this bending sidewall 32 is provided with the grasping plate pin 34 being held in the draw-in groove 33 on the projection 13 of insulating body 10 and diapire 11 lateral buckling towards insulating body 10, so that shielding casing 30 is retained on insulating body 10, and grasping plate pin 34 can provide electronic card coupler firm be welded on circuit board; Described inclination slider guide 14 can prevent the abnormal insertion of electronic cards, realizes electronic cards and docks with the reliable of electronic card coupler.

Refer to shown in Fig. 3 to Fig. 5, described conducting terminal 20 is arranged into two rows and is retained on described insulating body 10 before and after grafting direction, and in the present embodiment, described conducting terminal 20 inlays to bury shaping mode and be fixed on described insulating body 10.
