In the present embodiment, two clamping holes 1200 are formed on the clamping seat 120 of the clamping member 12 corresponding to the two clamping hooks 101 of the sliding rail 10, respectively, so that when each clamping member 12 is clamped into the groove 20 of the network card 2 by the clamping pin 121 to be installed at the clamping position, as shown in fig. 4, the clamping hooks 101 can respectively pass through the elastic deformation of the first connecting column and the second connecting column, so that the protruding blocks respectively connected with the first connecting column and the second connecting column respectively pass through the clamping holes 1200 of each clamping member 12, and after the protruding blocks respectively corresponding to the first connecting column and the second connecting column respectively pass through the clamping holes 1200, the protruding blocks respectively hook the clamping seat of the clamping member 12 by elastic deformation, thereby fixing the clamping member 12 on the sliding rail 10.
In this embodiment, as shown in fig. 4, the cross section of the pin 121 is substantially T-shaped, the length of the through slot 100 in the length direction of the slide rail 10 is greater than the length of the groove 20 of the network card 2 in the length direction of the slide rail 10, in this embodiment, the pin 121 has a first clamping block 1210 and a second clamping block 1211 connecting the clamping seat 120 and the first clamping block, the second clamping block 1211 is disposed between the two clamping holes 1200 of the clamping seat 120, wherein the length of the second clamping block 1211 in the length direction of the clamping seat 120 is greater than the length of the groove 20 of the network card 2 in the length direction of the slide rail 10, and the length of the groove 20 of the network card 2 in the length direction of the slide rail 10 is greater than the length of the first clamping seat 1211 in the length direction of the clamping seat 120, so that when the clamping piece 12 is mounted at the clamping position, the clamping pin 121 of the clamping piece 12 can be clamped into the groove 20 of the through slot 100 from the top of the slide rail 10, and the length of the second clamping block 1211 in the length direction of the slide rail 10 is greater than the length of the groove 121 in the length direction of the slide rail 10.

As shown in fig. 3, when the network card 2 is to be installed, the network card 2 is first inserted into the slide rail 10 and slid into the connecting terminal 21 along the slide rail 10 to be plugged into the clip connector 11, at this time, the groove 20 of the network card 2 is aligned with the through groove 100 of the slide rail 10, then the fastener 12 is aligned with the through groove 100 of the slide rail 10 in a downward manner by the fastener pin 121 to be snapped into the groove 20 of the network card 2 in a downward direction toward the bottom of the track, and is installed at the fastening position, at the same time, the hook 101 on the slide rail 10 penetrates through the fastening hole 1200 of the fastener 12, as shown in fig. 1 and 4, the fastener 12 is fixed on the slide rail 10, and the fastener pin 121 of the fastener 12 is snapped into the groove 20 of the network card 2 communicating with the through groove 100 to be installed at the fastening position, thereby restricting the sliding of the network card 2 on the slide rail 10, and restricting the network card 2 to the installation position, and completing the installation of the network card 2. When the network card 2 is to be removed, an external force can be applied to the hook 101 to make the first connecting column and the second connecting column of the hook 101 elastically deform due to the external force, so that the corresponding protruding blocks of the first connecting column and the second connecting column respectively do not hook the clamping seat of the clamping piece 12, the hook 101 can be separated from the clamping hole 1200 of the clamping piece 12 and the clamping piece 12 is pulled out in a direction away from the clamping seat, so that the clamping pin 121 of the clamping piece 12 is separated from the groove 20 of the network card 2, at this moment, the clamping pin 121 of the clamping piece 12 does not limit the network card 2 to slide on the sliding rail 10, that is, the network card 2 is not limited to the installation position by the clamping pin 121, so that the external force can be applied to draw the network card 2 away from the sliding rail 10, in order to prevent the clamping piece 12 from being lost due to random placement of the clamping piece 12, as shown in fig. 5, the clamping piece 12 can be turned over to make the clamping pin 121 of the clamping piece 12 face away from the sliding rail, and then pass through the clamping piece 12 to be combined with the idle position 10 on the sliding rail 10.
In summary, the card mounting mechanism of the present invention is provided with the fastening member 12 and the through slot 100 is formed on the sliding rail 10, so that the fastening pin 121 protruding from the fastening member 12 passes through the through slot 100 and then is fastened into the groove 20 of the card 2 inserted into the sliding rail 10, so as to lock the card 2 onto the circuit board 3, therefore, the card mounting mechanism of the present invention can still complete the mounting of the card 2 without the chassis frame, and the detachable design of the fastening member 12 of the present invention does not affect the mounting and fixing of the existing card with the fastening knob or the hand screw, so that the application range is wider.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
