Embodiment

Please consult Fig. 1 simultaneously to shown in Figure 3, part schematic diagram for three-dimensional exploded view of the present utility model, three-dimensional combination figure and another angle of insulating body, find out by knowing among the figure, the clip structure of card connector of the present utility model mainly is made up of an insulating body 1, an a pair of clip elastic arm 2 and a rotary body 3 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 4 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 one side in the card slot 11, electronic cards and plural terminals 4 is formed electrically connect; The dual-side of insulating body 1 is provided with profile groove 12 again, this profile groove 12 is used for installing the part of clip elastic arm 2, the interior proceeds posterolateral of this profile groove 12 is provided with the caulking groove 13 (as shown in Figure 3) of parallel this profile groove 12 again, and this insulating body 1 is provided with pivot hole 14 in the opposing party both sides away from card slot 11.

Clip elastic arm 2 is formed by the one-body molded processing of metal, it is again by a main part 21, one clip portion 22 and a linkage part 23 are formed, can be used to make electronic cards 5 strong fixs, this clip portion 22 by the front end of main part 21 forwards extend form, the end of this main part 21 is split into the first half and Lower Half, this first half bends inwards and extends to form one and be embedded sheet 24, make the first half of main part 21 and be embedded and form a bending side 241 between the sheet 24, this bending side 241 can increase the elastic force of clip elastic arm 2, after the Lower Half of this main part 21 extends back, and upwards being bent to form linkage part 23, this linkage part 23 is towards interior side-prominent bending.

Rotary body 3 is made by the insulation material, and it be the elongated body, is provided with the pivot 31 of an elongated at rotary body 3 near front bottom end, and also outwards protrude the both sides of pivot 31, and the pushing and pressing part 32 that is provided with a semicircular bodies is also outwards given prominence in the both sides of rotary body 3.

Said structure is when assembling clip elastic arm 2, the end of the main part 21 of clip elastic arm 2 is presented in the profile groove 12, this clip portion 22 and linkage part 23 protrude in the place ahead and the rear of insulating body 1 respectively, then main part 21 is pushed towards the place ahead, this is embedded 24 of sheets and can embeds in the caulking groove 13, make to be embedded sheet 24 and caulking groove 13 formation interference location, the end of main part 21 is positioned in the profile groove 12 simultaneously, therefore can make the firm dual reset position of clip elastic arm 2 formation.And then the pivot 31 of rotary body 3 is hubbed in the pivot hole 14 at insulating body 1 rear, rotary body 3 can be rotated in the rear of insulating body 1.

Please consult Fig. 4 to shown in Figure 5 in cooperation, stereogram when inserting for the utility model electronic cards, vertical view, stereogram and vertical view behind the electronic cards location, when in plant electronic cards 5, electronic cards 5 one sides are planted in the card slot 11 of insulating body 1 in the mode that from top to bottom tilts, then electronic cards 5 opposite sides are pressed down, after making electronic cards 5 form level, then with rotary body 3 to pressing down, the pushing and pressing part 32 of this rotary body 3 can be with linkage part 23 to extrapolation, make this linkage part 23 drive the clip portion 22 inside clampings in the place ahead, this clip portion 22 gets final product the firm dual-side that is held on electronic cards 5, to make electronic cards 5 can not pop up and withdraw from backward, therefore can form firm location.

The clip structure of the utility model card connector utilizes rotary body 3 to drive clip elastic arm 2 clamping electronic cards 5, make clip elastic arm 2 can not be subjected to the strength that electronic cards 5 is outwards pushed repeatedly, and be difficult for having the situation of distortion or elastic fatigue to produce, and, also has operational convenience with 2 starts of rotary body 3 control clip elastic arms.

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.
