[0020] The following is combined with Figure 1 —4 Provide further details of this application.

[0021] The present application embodiment discloses a relay circuit board, referring to Figure 1 - Figure 2 , including a circuit board body 1. When in use, the board body 1 is installed in the relay. Several electronic components 2 are installed on the surface of the board body 1. Several connecting seats 3 are installed at one end of the electronic components 2. A slide groove 7 is opened on the inner wall of the connecting seat 3. The inner wall of the slide groove 7 is connected to the connecting head 4, so that the connecting seat 3 is connected to the external equipment. A fixing hole 5 is opened inside the connecting head 4. The limit block 6 is installed in the connecting seat 3 with the help of a fixing ring 8. The fixing ring 8 pushes the limit block 6 to clamp the limit block 6 in the connecting hole 11. The limit block 6 is clamped with the connecting hole 11 with the help of the fixing ring 8, so that the connecting head 4 is kept installed in the connecting seat 3, and a pull block 9 is installed at one end of the fixing ring 8. The bottom end of the fixing ring 8 is bent by pulling the pull block 9, so that the limit block 6 at the bottom end of the fixing ring 8 is separated from the fixing hole 5, and the connecting head 4 can be disassembled, thereby avoiding the problem of inconvenience in installation and disassembly of the connecting head 4, effectively improving the efficiency of installation of the connecting head 4, and facilitating later maintenance.

[0022] Reference Figure 2A connecting hole 11 is formed through the inner wall of the connecting seat 3 and the fixing ring 8. A fixing bolt 12 is threadedly connected to the inner wall of the connecting hole 11. The fixing ring 8 is installed in the connecting seat 3 with the help of the fixing bolt 12, thereby avoiding the fixing ring 8 from being separated from the connecting seat 3, effectively improving the stability of the device. A spring 10 is installed on the inner wall of the fixing ring 8. The inner wall of the fixing ring 8 is supported by the spring 10, which effectively improves the pushing effect of the fixing ring 8 on the limit block 6, ensures the use effect of the device, and avoids the fixing ring 8 from losing its elasticity after repeated use, resulting in the limit block 6 being difficult to engage with the fixing hole 5.

[0023] Reference Figure 3 - Figure 4 , a shielding plate 13 made of rock wool is installed at the bottom of the plate body 1. When moisture from the outside enters the circuit board of the relay, the moisture can be absorbed by taking advantage of the water-absorbing effect of the rock wool, thereby reducing the water content of the air in the relay and effectively preventing moisture from corroding the electronic components 2 on the surface of the circuit board. Two fixing blocks 14 are installed on the top of the shielding plate 13. The surfaces of the two fixing blocks 14 are snap-fitted with the limiting holes 15 in the plate body 1. The shielding plate 13 is connected to the plate body 1 with the help of the fixing blocks 14 and the limiting holes 15, and the fixing blocks 14 are separated from the limiting holes 15, so that the shielding plate 13 can be replaced conveniently.

[0024] The implementation principle of a relay circuit board in the embodiment of the present application is as follows: by installing the limit block 6 in the connecting seat 3 with the help of the fixing ring 8, the fixing ring 8 pushes the limit block 6 to clamp the limit block 6 in the connecting hole 11 in the connecting head 4, and a pull block 9 is installed at one end of the fixing ring 8 to facilitate the clamping of the limit block 6 and the connecting hole 11 with the help of the fixing ring 8, so that the connecting head 4 is kept installed in the connecting seat 3, and the limit block 6 can be separated from the fixing hole 5 by pulling the pull block 9 to remove the connecting head 4, thereby avoiding the problem of inconvenience in installation and removal of the connecting head 4, and the connecting seat 3 and A connecting hole 11 is formed through the inner wall of the fixing ring 8, and a fixing bolt 12 is threadedly connected to the inner wall of the connecting hole 11, so that the fixing ring 8 can be installed in the connecting seat 3 with the help of the fixing bolt 12, thereby avoiding the situation where the fixing ring 8 is separated from the connecting seat 3, and effectively improving the stability of the device. A spring 10 is installed on the inner wall of the fixing ring 8, so that the inner wall of the fixing ring 8 can be supported by the spring 10, effectively improving the pushing effect of the fixing ring 8 on the limit block 6, and avoiding the situation where the fixing ring 8 loses its elasticity after repeated use, resulting in the limit block 6 being difficult to engage with the fixing hole 5.

[0025] A baffle plate 13 made of rock wool can also be installed at the bottom of the plate body 1, so that when moisture from the outside enters the circuit board of the relay, the moisture can be absorbed by taking advantage of the water-absorbing effect of the rock wool, effectively preventing moisture from corroding the electronic components 2 on the surface of the circuit board. Two fixing blocks 14 are installed on the top of the baffle plate 13, and the surfaces of the two fixing blocks 14 are snap-fitted with the limiting holes 15 in the plate body 1, so that the baffle plate 13 can be connected to the plate body 1 with the help of the fixing blocks 14 and the limiting holes 15, and the fixing blocks 14 can be separated from the limiting holes 15, so as to facilitate the replacement of the baffle plate 13.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
