Embodiment

Please consult Fig. 1 simultaneously to shown in Figure 5, be the vertical view of three-dimensional exploded view of the present utility model, three-dimensional combination figure, part rearview, buckle elastic arm and the end view of buckle elastic arm, find out by knowing among the figure, the buckle structure of card connector of the present utility model mainly is made up of an insulating body 1 and a pair of buckle elastic arm 2 that is assembled in insulating body 1 both sides, so with regard to the primary structure feature of this case describe in detail as after, be defined as the place ahead with the electronic cards direction of insertion in the present embodiment;

Wherein:

Insulating body 1 is the framework of a lengthwise shape, is provided with plural terminals 3 in it, is provided with a card slot 11 in the front side of insulating body 1, and by this, the user can plant electronic cards 4 one sides in the card slot 11, electronic cards 4 is formed with plural terminals 3 electrically connect; The dual-side of insulating body 1 is provided with profile groove 12 again, and this profile groove 12 is used for installing the part of buckle elastic arm 2, and the interior proceeds posterolateral of this profile groove 12 is provided with a caulking groove 13 (as shown in Figure 3) that is listed in this profile groove 12 again.

Buckle elastic arm 2 is formed by the one-body molded processing of metal, it is made up of a main part 21, a location division 22 and a clamping part 23 again, can be used to make electronic cards 4 strong fixs that insert insulating body 1, the rear end of this main part 21 reaches the below respectively upward and forms projecting end 211, make projecting end 211 can interfere internal face, to make main part 21 strong fix more at profile groove 12; After this location division 22 is bent inwards by the end of main part 21, extend towards the direction of clamping part 23 again and form, make this location division 22 be listed in the inboard of main part 21, and be parallel to each other with main part 21, and form a cambered surface 210 between main part 21 and the location division 22 again, this cambered surface 210 can increase the elastic displacement scope of buckle elastic arm 2, is provided with the tongue piece 221 that can interfere in the caulking groove 13 of insulating body 1 on this location division 22 again; Clamping part 23 has a stop tab 231 of forwards being extended away from the opposite side of end by main part 21, and one by main part 21 holding piece 232 that forwards extends again of bending upwards, wherein, the front bottom end of stop tab 231 bonding pad 233 that bends inwards again, these holding piece 232 front ends form top holding piece 234 and side holding piece 235 again respectively, the central authorities of holding piece 232 are further outwards bending one lug 236 again, and this lug 236 can prevent that holding piece 232 from upwards being pullled and be out of shape.

By said structure in when assembling, after being presented to the part of the main part 21 of buckle elastic arm 2 in the profile groove 12, this location division 22 can protrude from the rear of insulating body 1, then the location division of protruding 22 is pushed towards the place ahead, 22 of this location divisions can place in the caulking groove 13, make the tongue piece 221 on the location division 22 form the interference location with caulking groove 13, the projecting end 211 at main part 21 rears is also interfered the internal face at profile groove 12 simultaneously, therefore can make buckle elastic arm 2 form firm dual reset position.The clamping part 23 of the buckle elastic arm 2 behind the location protrudes in the place ahead, both sides of insulating body 1, and form ㄇ word shape structure (as shown in Figure 2) jointly with insulating body 1, wherein stop tab 231 is positioned at the outside of holding piece 232, can avoid holding piece 232 excessively to expand outwardly and be out of shape, and the bonding pad 233 of stop tab 231 front ends is welded on the circuit board, it is fixing making stop tab 231, and can increase the steadiness of clamping part 23, in addition, the lug 236 of holding piece 232 central authorities is resisted against the bottom surface of stop tab 231, is subjected to external force upwards to pull and be out of shape or lose elastic force to avoid holding piece 232.As above structural design makes buckle elastic arm 2 have splendid steadiness and elasticity.

When in plant electronic cards 4, electronic cards 4 one sides are planted in the card slot 11 in the mode that from top to bottom tilts, holding piece 232 can be subjected to the pressure of electronic cards 4 and elastic displacement laterally, then electronic cards 4 opposite sides are pressed down, make electronic cards 4 form level, 232 elastic resets of holding piece, top holding piece 234 and side holding piece 235 are resisted against respectively in the draw-in groove 41 of the end face of electronic cards 4 both sides and electronic cards 4 both sides, to make electronic cards 4 can not pop up and withdraw from backward, therefore can form firm location.

The buckle elastic arm 2 of the buckle structure of the utility model card connector has main part 21 and location division 22 can be fixed on the insulating body 1 simultaneously, form firm dual reset position, and has a cambered surface 210 between main part 21 and the location division 22, and can increase the elastic displacement scope of buckle elastic arm 2, so can make buckle elastic arm 2 can bear bigger extrapolability, and can effectively avoid 2 distortion of buckle elastic arm; And clamping part 23 has the design of stop tab 231 and holding piece 232 again, and clamping part 23 not only can firmly be held on the electronic cards 4, is difficult for strain or warpage again and damages, and can increase the intensity and the life-span of clamping part 23 again.

Above-mentioned detailed description is at a kind of preferable embodiments possible explanation of the present utility model, be not in order to limit claim of the present utility model, all other do not break away from the equalization of being finished under the skill spirit that the utility model discloses to be changed and modifies change, all should be contained in the claim that the utility model contains.
