In some embodiments, the first height H1 is greater than the second height H2. The first height H1 is greater than the second height H2 such that the electronic component 700 (shown in fig. 1) is easier to enter the slot 122b through the first opening 122b1 when engaging with the slot 122 b.

Fig. 6A is a perspective view showing a fixing manner of the conductive foam 200 according to an embodiment of the invention. As shown in fig. 6A, the conductive foam 200 provides an electrical connection for the electronic component 700. Please refer to fig. 1 and fig. 6A. In some embodiments, the electronic component 700 needs to be in contact with the substrate 900 to achieve a grounding effect. For example, the electronic component 700 is a solid state disk, and the solid state disk needs to be grounded by electrically connecting a metal screw hole at one end of the solid state disk and the substrate 900 (e.g., a circuit board). Specifically, in some embodiments, after the electronic component 700 is fastened to the connector 120, two opposite surfaces of the conductive foam 200 are respectively in contact with the electronic component 700 and the substrate 900, so as to form an electrical connection between the electronic component 700 and the substrate 900. In some embodiments, the conductive foam 200 enters the slot 122b from the second opening 122d to contact the electronic component 700. In some embodiments, the conductive foam 200 is also in contact with the end face 122b 2. In some embodiments, the shape of the conductive foam 200 is a rectangular parallelepiped, but the invention is not limited thereto.

Referring to FIG. 6B, a cross-sectional view of the structure shown in FIG. 6A taken along section line 6B-6B is shown. As shown in fig. 6B, the electronic assembly 700 is fastened to the connector 120. In some embodiments, the engaging block 122e is engaged with a groove at one end of the electronic component 700 (e.g., a solid state disk). The conductive foam 200 contacts with one side of the electronic component 700 along the third direction a 3. Please refer to fig. 3A and fig. 6B. In some embodiments, the conductive foam 200 contacts the bottom surface 122e1 of the snap block 122 e. The bottom surface 122e1 of the engaging block 122e is parallel to the second surface 122c to help the conductive foam 200 to contact the electronic component 700 more firmly.

As will be apparent from the above detailed description of the embodiments of the present invention, in the fastening device of the present invention, the plurality of sets of slots of the two fixing strips and the two resilient tenons of the connecting member can achieve the purpose of assembling and replacing electronic components with different specifications without additionally damaging the substrate (e.g., drilling holes in the substrate). The clamping tenons are provided with pressing pieces, so that a user can conveniently and easily unlock the fastening of the fixing strip and the connecting piece by pressing the two clamping tenons simultaneously. The raised strips and the clamping blocks in the slots of the connecting piece can help to fix the electronic assembly and the connecting piece. The conductive foam provides a grounding mode, so that the electronic assembly can still have a grounding effect when being fixed by the buckling device.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the present invention.
