As shown in fig. 3A, in some embodiments, the fastening body 122 further includes a fastening block 122e. The engagement block 122e is connected to the distal end surface 122b2. The engaging block 122e has a cambered surface 122e2. The arc surface 122e2 protrudes from the end surface 122b2 toward the first opening 122b 1. In some embodiments, the arcuate surface 122e2 may be a portion of an arcuate surface. The engaging block 122e also has a bottom surface 122e1. The bottom surface 122e1 connects the edge of the cambered surface 122e2 with the end surface 122b2. In some embodiments, the bottom surface 122e1 is parallel to the second surface 122c. In some embodiments, the other end of the electronic assembly 700 (shown in fig. 1) has a recess (not shown), such as a metal screw hole. When the other end of the electronic component 700 is inserted into the slot 122b of the connector 120, the groove and the engaging block 122e are engaged with each other, so as to assist in fixing the electronic component 700 and the connector 120.

Referring to fig. 3B, a perspective view of another view of the connecting member 120 of the fastening device 100 shown in fig. 2 is shown. As shown in fig. 3A and 3B, in some embodiments, the engaging process of the electronic component 700 (shown in fig. 1) and the connector 120 is described as follows.

The engagement is completed when one end of the electronic component 700 touches the end surface 122b 2.

Referring to fig. 4, an enlarged view of a portion of the fastening device 100 shown in fig. 2 is shown. As shown in fig. 4, in some embodiments, the latch 124 includes a hook 124a and a resilient arm 124b. Referring to fig. 2 and 4, the hook 124a is configured to detachably engage with the slot 112. The elastic arm 124b is connected between the fastening body 122 and the hook 124 a. The operation of the hook 124a and the resilient arm 124b will be described in the description of fig. 5A.

Please refer to fig. 2 and fig. 4. In some embodiments, the connector 120 further comprises two press tabs 126. The two pressing pieces 126 are connected to the two locking tongues 124, respectively. The two pressing pieces 126 are respectively accommodated in the two accommodating grooves 114 connected with the corresponding clamping grooves 112. When the pressing piece 126 is accommodated in the accommodating groove 114, the pressing piece 126 is spaced apart from the top surface 110a of the adjacent fixing strip 110 by a distance D1 in the first direction A1. The push tab 126 is designed to facilitate the separation of the attachment strap 110 from the connector 120. The distance D1 provides a space between the pressing piece 126 and the fixing bar 110, facilitating the pressing of the pressing piece 126 by an operator. In some embodiments, the pressing piece 126 is rectangular, but the invention is not limited thereto.

Referring to FIG. 5A, a cross-sectional view of the structure shown in FIG. 4 is shown as cut lines 5A-5A. As shown in fig. 5A, the elastic arm 124b has compressibility in the first direction A1. Next, please refer to fig. 4 and fig. 5A. The hook 124a and the slot 112 are detachably fastened and fixed to each other due to the compressible property of the elastic arm 124b in the first direction A1. When the elastic arm 124b is compressed toward the fastening body 122 along the first direction A1, the hook 124a will approach the fastening body 122 along the first direction A1 and separate from the slot 112. Referring to fig. 2, in fig. 2, the third direction A3 is perpendicular to the first direction A1 and the second direction A2. The operator can press the locking tongues 124 on both sides of the connecting piece 120 (by pressing the two pressing pieces 126) to disengage from the locking grooves 112, and then lift the connecting piece 120 along the third direction A3. The connecting piece 120 can be separated from the two fixing strips 110.

Referring to FIG. 5B, a cross-sectional view of the structure shown in FIG. 4 is shown as cut lines 5B-5B. As shown in fig. 5B, the first opening 122B1 and the end surface 122B2 have a first height H1 and a second height H2, respectively, in the third direction A3. 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 the electronic component 700 (shown in fig. 1) is easier to enter the slot 122b through the first opening 122b1 when engaged with the slot 122 b.

Referring to fig. 6A, a perspective view of a fixing manner of the conductive foam 200 according to an embodiment of the invention is shown. As shown in fig. 6A, the conductive foam 200 provides an electrical connection for the electronic assembly 700. Next, please refer to fig. 1 and fig. 6A. In some embodiments, the electronic assembly 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 grounding of the solid state disk is achieved 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 buckled with the connector 120, opposite sides of the conductive foam 200 are respectively contacted with the electronic component 700 and the substrate 900 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 conductive foam 200 is rectangular, but the invention is not limited thereto.

Referring to FIG. 6B, a cross-sectional view of the structure shown in FIG. 6A is shown as cut by the cutting line 6B-6B. As shown in fig. 6B, the electronic component 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 a side of the electronic component 700 along the third direction A3. Next, please refer to fig. 3A and fig. 6B. In some embodiments, the conductive foam 200 is in contact with 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 more firmly contact the electronic component 700.

As is apparent from the above description of the embodiments of the present invention, in the fastening device of the present invention, the plurality of sets of the clamping grooves of the two fixing strips and the elastic two clamping tenons of the connecting piece can achieve the purpose of assembling and replacing electronic components with different specifications without additionally damaging the substrate (for example, drilling holes in the substrate). The clamping tenons are provided with pressing sheets, so that a user can easily unlock the buckling of the fixing strip and the connecting piece by pressing the two clamping tenons simultaneously. The convex strips and the clamping blocks in the connecting piece slots can help the electronic component to be fixed with the connecting piece. The conductive foam provides a grounding mode, so that the grounding effect can be maintained when the electronic component is fixed through the buckling device.

Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited to the embodiments described above, and that various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the present invention, and the scope of the present invention is defined by the appended claims.
