The two pressing pieces 126 are respectively connected with the two tenons 124. The two pressing pieces 126 are respectively accommodated in the two accommodating grooves 114 connected to the corresponding slot 112. When the pressing piece 126 is accommodated in the accommodating groove 114, the pressing piece 126 is separated from the top surface 110a of the adjacent fixing bar 110 by a distance D1 in the first direction A1. The pressing piece 126 is designed to facilitate the separation of the fixing strip 110 and the connecting piece 120. The distance D1 provides a space between the pressing piece 126 and the fixing bar 110 to facilitate the operator to press the pressing piece 126. In some embodiments, the shape of the pressing piece 126 is rectangular, but the present disclosure is not limited to this.

As shown in FIG. 5B, the first opening 122b1 and the end surface 122b2 are above the third direction A3, and respectively have a first height H1 and a second height H2. 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, so that when the electronic component 700 (as shown in FIG. 1) is engaged with the slot 122b, it is easier to enter the slot 122b through the first opening 122b1.

Please refer to FIG. 6A, which is a perspective view showing a fixing method of the conductive foam 200 according to an embodiment of the present disclosure. As shown in FIG. 6A, the conductive foam 200 provides an electrical connection method for the electronic component 700. Then please refer to Figure 1 and Figure 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 drive, and the grounding of the solid state drive needs to be achieved by electrically connecting a metal screw hole at one end of the solid state drive and the substrate 900 (for example, a circuit board). Specifically, in some embodiments, after the electronic component 700 is buckled with the connector 120, two opposite sides of the conductive foam 200 are in contact with the electronic component 700 and the substrate 900 respectively, so as to form a gap between the electronic component 700 and the substrate 900. Electric connection. In some embodiments, the conductive foam 200 enters the slot 122b through the second opening 122d to contact the electronic component 700. In some embodiments, the conductive foam 200 is also in contact with the end surface 122b2 at the same time. In some embodiments, the shape of the conductive foam 200 is a rectangular parallelepiped, but the disclosure is not limited to this.

Please refer to Figure 6B, which is a cross-sectional view of Figure 6A cut by the cutting line 6B-6B. As shown in FIG. 6B, the electronic component 700 is buckled with the connector 120. In some embodiments, the engaging block 122e is engaged with a groove at one end of the electronic component 700 (for example, a solid state drive). The conductive foam 200 is in contact with one side surface of the electronic component 700 along the third direction A3. Then please refer to Figure 3A and Figure 6B. In some embodiments, the conductive foam 200 is in contact with the bottom surface 122e1 of the engaging block 122e. The bottom surface 122e1 of the engaging block 122e is parallel to the second surface 122c to help the conductive foam 200 to more firmly contact the electronic component 700.

From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that in the fastening device of the present invention, the multiple sets of grooves of the two fixing strips and the two elastic tenons of the connecting member can be damaged without additional damage. In the state of the substrate (for example, drilling holes on the substrate), the purpose of assembling and replacing electronic components of different specifications is achieved. The tenon has a pressing piece, which is convenient for the user to easily release the buckle between the fixing strip and the connecting piece by pressing the two tenons at the same time. The protruding strips and clamping blocks in the connector slot can help fix the electronic component and the connector. Conductive foam provides a grounding method, so that when the electronic components are fixed through the buckle device, the grounding effect can be maintained.
