[0038] The board connector 3 passes through the first cover plate 1 and the second cover plate 2, and its two ends are connected to the filter base plate 51 and the printed circuit board 6, respectively.

[0039] Compared to the existing technology where the printed circuit board 6 and filter 5 module are connected by tapping and soldering the board-to-board connector through a window on the back of the filter 5, which not only affects the appearance but also results in poor heat dissipation and electromagnetic shielding of the filter 5 and poses a risk to waterproofing, this embodiment places the inter-board connector 3 inside the cavity of the filter 5, with one end connected to the filter base plate 51 and the other end connected to the printed circuit board 6. A first cover plate 1 and a second cover plate 2 are provided to fix the inter-board connector 3, avoiding the need for a window on the back. Figure 2 As shown, reducing the number of teeth improves the overall heat dissipation and electromagnetic shielding capabilities of the machine.

[0040] Specifically, such as Figure 3 As shown, in this embodiment, the filter base plate 51 is provided with a receiving groove 511 for accommodating the first cover plate 1 and the second cover plate 2. The first cover plate 1 and the second cover plate 2 are stacked in the receiving groove 511.

[0041] Furthermore, such as Figure 1 As shown, it also includes a mounting bracket 4 for mounting the inter-board connector 3. Exemplarily, the mounting bracket 4 has a cylindrical structure with a first mounting through hole 41 at its center.

[0042] The first cover plate 1 and the filter base plate 5 are detachably connected, for example, by means of screws and pins to fix it to the filter base plate 51. Figure 5 As shown, the shape of the first cover plate 1 matches the bottom of the receiving groove 511.

[0043] The first cover plate 1 has second mounting through holes 11 at both ends, and the mounting bracket 4 passes through the second mounting through holes 11. Exemplarily, in this embodiment, the mounting bracket 4 is press-fitted into the second mounting through holes 11.

[0044] The first cover plate 1 has a hollow structure to reduce the overall weight of the filter 5. For example, the first cover plate 1 is a low-frequency signal shielding cover to prevent signal leakage from the filter 5.

The first mating part and the second mating part are connected to each other to further prevent signal leakage of the filter 5.

[0046] like Figure 5 and Figure 6 As shown, the first mating part is a protrusion 12 formed on the edge of the first cover plate 1, such as... Figure 3 and Figure 4 As shown, the second mating part is a groove 5111 formed on the side wall of the receiving groove 511, and the protrusion 12 is inserted into the groove 5111.

[0047] The length direction of the groove 5111 is the same as the height direction of the side wall of the receiving groove 511, and its top opening is at the upper edge of the side wall. The protrusion 12 is a strip-shaped protrusion that matches the groove 5111.

[0048] Furthermore, in order to improve the connection stability and positioning accuracy between the second cover plate 2 and the base plate of the filter 5, and to facilitate disassembly and assembly, such as... Figure 4 and Figure 6 As shown, the cross-section of the groove 5111 and the protrusion 12 perpendicular to their height is a T-shaped structure.

[0049] The second cover plate 2 is stacked on the first cover plate 1, and the second cover plate 2 and the first cover plate 1 are detachably connected, for example by means of screws and pins.

[0050] like Figure 7 As shown, the second cover plate 2 has a third mounting through hole 21 at each end; the first mounting through hole 41 and the third mounting through hole 21 are coaxially arranged, and the inter-plate connector 3 passes through the first mounting through hole 41 and the third mounting through hole 21 in sequence.

[0051] For example, the second cover plate 2 is a PCB aluminum plate to meet the heat dissipation requirements of the filter 5 and improve the heat dissipation capacity of the whole machine.

[0052] like Figure 8 As shown, two inter-board connectors 3 are provided, respectively located at both ends of the first cover plate 1 and the second cover plate 2. The inter-board connector 3 includes a first connecting end 31, a second connecting end 32, and an intermediate section 33. The first connecting end 31 is connected to the filter base plate 51, and the second connecting end 32 is connected to the printed circuit board 6, forming an electrical connection. The intermediate section 33 passes through the first mounting through hole 41 and the third mounting through hole 21. Conductive sealant is applied between the second cover plate 2 and the inter-board connector 3; exemplarily, the conductive sealant is FIP dispensing, to achieve electromagnetic shielding between the second cover plate 2 and the inter-board connector 3.

[0053] In this embodiment, the second connection end 32 is a welding end, which is welded and fixed to the printed circuit board 6; the first connection end 31 is screwed to the filter base plate 51 by threads.

[0054] The usage method of this embodiment is as follows:
