The cover body 3 has a plurality of partition ribs 31 protruding from the side facing the PCB board 2. The partition ribs 31 abut against the surface of the PCB board 2 to stabilize the position of the PCB board 2. The above design makes it unnecessary to divide the PCB board 2 into holes for the partition ribs 31, which reduces the processing difficulty. Secondly, the design also improves the shielding effect of the PCB board 2, that is, there is no need to clean the holes for the partition ribs 31. Moreover, it makes it convenient to route the lines of the PCB board 2.

[0039] The above-mentioned structures are described in detail below.

[0040] In this embodiment, please refer to Figure 5 A connecting piece is provided on the bottom wall inside the bottom shell 1, and the connecting piece is detachably connected to the cover body 3 at one end away from the bottom wall of the bottom shell 1 to realize the disassembly and assembly of the cover body 3 and the bottom shell 1. Specifically, the connecting piece includes no more than three first hollow connecting shafts 11, and the first hollow connecting shafts 11 are fixedly connected to the bottom wall inside the bottom shell 1 in a side-by-side manner. Moreover, it should be noted that the first hollow connecting shaft 11 is connected to the top of the cover body 3 at one end away from the bottom wall of the bottom shell 1 through a first fastening screw 4, that is, the first fastening screw 4 passes through the cover body 3 and is plugged into the top opening of the first hollow connecting shaft 11 to realize the connection between the first hollow connecting shaft 11 and the bottom shell 1.

[0041] Regarding the number of the first hollow connecting shafts 11 , in the present embodiment, the number of the first hollow connecting shafts 11 is three, but in practice, the number of the first hollow connecting shafts 11 may also be one or two.

[0042] For details, please refer to Figure 5 As far as the first fastening screw 4 passes through the cover body 3 and is plugged into the top opening of the first hollow connecting shaft 11, the top of the first hollow connecting shaft 11 is located below the cover body 3, and the first fastening screw 4 passes through the cover body 3 and is interference fit with the first hollow connecting shaft 11, so that the connecting piece on the cover body 3 presses the PCB board 2 more, thereby making the PCB board 2 more closely attached to the bottom wall of the bottom shell 1, thereby achieving a grounding effect.

[0043] In this embodiment, please refer to Figure 2 and Figure 3 The PCB board 2 is provided with an avoidance hole 21, and the avoidance hole 21 is plugged with the connector so that the bottom of the PCB board 2 is in contact with the bottom wall inside the bottom shell 1. This setting can realize the positioning of the PCB board 2.

[0044] Furthermore, the left and right sides of the PCB board 2 are fastened to the bottom wall of the bottom shell 1 by a plurality of second fastening screws 5 , thereby stabilizing the position of the PCB board 2 .

[0045] As for the connection between the cover 3 and the bottom shell 1, please refer to Figure 1 and Figure 4 In this embodiment, the cover body 3 is fastened to the top of the bottom shell 1 by a plurality of third fastening screws 6 to achieve the cover connection between the cover body 3 and the bottom shell 1, thereby also connecting the connector to the cover body 3, so that the partition rib block 31 on the cover body 3 is fully in contact with the PCB board 2.

[0046] It should be noted that the plurality of partition rib blocks 31 include a first partition rib block 311 and a second partition rib block 312. The cross-section of the first partition rib block 311 is T-shaped, and the cross-section of the second partition rib block 312 is rectangular. The first partition rib blocks 311 are arranged in an array on both sides of the surface of the PCB board 2; the second partition rib blocks 312 are arranged at intervals in the first partition rib blocks 311 and are distributed in an array. The second partition rib blocks 312 and the first partition rib blocks 311 form a shielding space on the surface of the PCB board 2. Therefore, the partition rib block 31 can fully separate the signals of each channel on the PCB board 2 and enhance the shielding effect.

[0047] In this embodiment, please refer to Figure 1 and Figure 2 A plurality of second hollow connecting shafts 12 are arranged on the side wall of the bottom shell 1 in the vertical direction, and the third fastening screws 6 penetrate the cover body 3 and are plugged into the second hollow connecting shafts 12 , thereby fastening the cover body 3 to the bottom shell 1 .

[0048] For details, please refer to Figure 2 and Figure 3The two second hollow connecting shafts 12 oppositely arranged on the side wall of the bottom shell 1 constitute a group of second hollow connecting shafts 12. A clamping plate 121 is extended outside at least two groups of second hollow connecting shafts 12 along the central axis direction of the shell. In this embodiment, there are two groups of second hollow connecting shafts 12. The PCB board 2 is provided with a clamping groove 22 clamped with the clamping plate 121 around it. The clamping groove 22 is clamped with the clamping plate 121 to further fix the position of the PCB board 2.

[0049] In other embodiments, there may also be three sets of second hollow connecting shafts 12 .

[0050] In essence, the above design can stabilize the position of the PCB board 2 in the bottom shell 1 by engaging the card slot 22 with the card plate 121 and cooperating with the left and right sides of the PCB board 2 to be fastened and attached to the bottom wall of the bottom shell 1 through a plurality of second fastening screws 5. Secondly, this design does not require more second fastening screws 5 to fix the PCB board 2 in the bottom shell 1 in the middle or other positions of the PCB board 2, which greatly reduces the processing difficulty. Thirdly, it also reduces labor costs, and the operator does not need to perform too many screw tightening operations.
