【Detailed ways】

The preferred embodiment of the utility model is described in detail below, please refer to Figure 1 and Figure 2, the utility model buckling device 1 and a pair of electrical connectors 4 located at its front and rear sides are jointly assembled on a circuit board 5, the buckle Between the front and rear sides of the holding device 1 and the electrical connector 4 are respectively spaces for accommodating the electronic card 6 . The two electronic cards 6 are placed back to back, the front ends of which are respectively inserted into the electrical connectors 4 , and the tail ends are fixed by the buckling device 1 .

Referring to FIG. 3 , the buckling device 1 includes a base body 2 made of insulating material and a pair of buckling parts 3 fixed on the front and rear sides of the base body 2 . The front and rear sides of the base 2 respectively form spaces for electronic cards to be accommodated. The base 2 includes a lengthwise base 20 and side portions 21 extending from both ends of the base 20 to the front and rear respectively, and the base 2 is in the shape of an "I". The front and rear sides of the base 20 respectively extend upward from the bottom to form a pair of clamping parts 200 , and a clamping groove 201 is formed between them and the base 20 . A pair of through holes 202 penetrating forward and backward are defined on the base 20 between the two clamping portions 200 on the same side. The front and rear sides of the side portion 21 are respectively provided with a positioning post 210 and a stopper 211 extending upward from the surface. A soldering tab 22 is respectively inserted into the front and rear ends of the side portion 21 for fixing the base 2 to the circuit board.

The buckle 3 includes a connecting part 30 in the middle and elastic arms 31 extending from the connecting part 30 to the left and right ends. Section 33. A pair of through holes 300 are defined on the connecting portion 30 .

When the two buckling parts 3 are installed on the base 2 , the connecting part 30 of the buckling part 3 is roughly located between the two clamping parts 200 on the same side of the base 2 , and the elastic arm is located in the clamping groove 201 . The stopper 211 on the side portion 21 of the base is located at the front side of the pulling portion 33 of the buckle 3 to limit its excessive deflection. The perforated holes 300 on the two fastening parts 33 and the through holes 202 on the base correspond to each other, and a pair of rivets 7 are sequentially passed through and then riveted, thereby connecting the three. The rivet 7 shown in FIG. 3 is a riveted structure. After the two fastening parts 3 are assembled, they are respectively fixed on the opposite front and rear sides of the base 2 and arranged back to back. Each fastening member 3 has two fastening portions 32 at its ends. The fastening portions 32 of different fastening pieces are located on opposite front and rear sides of the base, and bend and extend in opposite directions respectively. In the front-rear direction of the base, the line connecting the two buckling parts 32 at the front side of the base is parallel to the line connecting the two buckling parts 32 at the rear side. In the left-right direction perpendicular to the front-rear direction of the base, the connecting line of the latching portions 32 on the left side of the base is parallel to the connecting line of the latching portions 32 on the right side. According to the arrangement of the above buckling parts, a pair of electronic cards 6 can be buckled symmetrically and back-to-back on opposite front and rear sides of the buckling device 1 . The buckling portion 32 of the buckling member 3 is locked on the surface of the rear end of the electronic card, and the positioning post 210 of the base 2 is located in a corresponding hole (not numbered) at the rear end of the electronic card 6 . When the electronic card 6 needs to be released, the pulling part 33 of the buckle 3 is pulled backward, and the buckle part 32 is removed from the surface of the electronic card, so that the electronic card can be taken off.

The above is the description of the best embodiment of the utility model. According to this idea, many other implementations can be derived, such as the base and the buckle are integrated, as long as they have the corresponding buckle function. As another example, in the preferred embodiment, each buckle is placed parallel to the end edge of the electronic card, and the two buckle parts on it are buckled on the same electronic card. It is also feasible to place them in a vertical direction, and the buckling parts at both ends of the electronic cards respectively buckle different electronic cards. Of course, the buckling parts do not necessarily have to be formed on the same buckling part two by two, and each independent setting can still realize the creative idea of the utility model.
