[0022] Example 1

[0023] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a dual-duplex module for preventing signal interference, including a protective component 1, the protective component 1 includes a shell 11, the top of the shell 11 is movably connected to a cover body 12 through a hinge, the inner cavity of the shell 11 is provided with a module body 2, the top of the cover body 12 is fixedly connected to a buffer strip 13, the module body 2 includes a substrate 21, the surface of the substrate 21 is provided with a shielding coating 22, the surface of the shielding coating 22 is provided with an inhibitory coating 23, the surface of the inhibitory coating 23 is provided with a waterproof layer 24, and the surface of the waterproof layer 24 is provided with a wear-resistant layer 25.

[0024] like Figure 1 , 2 As shown in FIG. 4 , the module body 2 is placed inside the shell 11, and the shell 11 and the cover 12 can protect the module body 2. The shell 11 and the cover 12 can initially reflect external electromagnetic waves, thereby reducing interference. When subjected to external collision, the buffer strip 13 can effectively buffer the impact force, thereby preventing the module body 2 from directly colliding with external objects, thereby causing unstable connection and interference. During use, the wear-resistant layer 25 can improve the wear resistance and corrosion resistance of the substrate 21, and the waterproof layer 24 can effectively ensure that the substrate 21 is not invaded and damaged by moisture. The ability of the coating 23 to absorb or attenuate external electromagnetic waves is suppressed, thereby reducing interference. The shielding coating 22 can effectively block the penetration of external electromagnetic fields and reduce interference, thereby improving the anti-interference ability of the substrate 21.

[0025] Example 2

[0026] Reference Figure 1 , 2 , 3 and 5 are the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, a connection port 111 is provided on the front surface of the housing 11 , and a limiting pad is disposed in the inner cavity of the connection port 111 .

[0028] Both sides of the front end of the bottom of the cover body 12 are fixedly connected with connecting blocks 121, and the front of the connecting block 121 is fixedly connected with a spring piece 122. Both sides of the front end of the top of the shell 11 are provided with connecting grooves 112. The connecting block 121 and the spring piece 122 extend to the inner cavity of the connecting groove 112 and are movably connected with the inner cavity of the connecting groove 112.

[0029] A positioning groove 113 is formed on the front side of the inner cavity of the connecting groove 112 . One end of the spring piece 122 away from the connecting block 121 extends to the inner cavity of the positioning groove 113 and is movably connected to the inner cavity of the positioning groove 113 .

[0030] like Figure 1 , 2 As shown in Figures 3 and 5, the connection port 111 facilitates the connection between the module body 2 and the outside. The cover body 12 drives the connecting block 121 and the spring piece 122 downward into the inner cavity of the connecting groove 112, thereby limiting the connection between the cover body 12 and the shell 11. At the same time, the spring piece 122 enters the inner cavity of the positioning groove 113, thereby fixing the connection between the cover body 12 and the shell 11.

[0031] Example 3

[0032] Reference Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, the shielding coating 22 is coated on the surface of the substrate 21, and the suppression coating 23 is coated on the side of the shielding coating 22 away from the substrate 21. The shielding coating 22 is usually composed of a composite material containing metal particles, and the suppression coating 23 usually contains an absorbing material, such as ferrite, ferrite composite material, etc.

[0034] The waterproof layer 24 is coated on the side of the suppression coating 23 away from the shielding coating 22, and the wear-resistant layer 25 is coated on the side of the waterproof layer 24 away from the suppression coating 23. The waterproof layer 24 is a silicone coating, and the wear-resistant layer 25 is a hard coating.

[0035] like Figure 4 As shown, the waterproof layer 24 is a silicone coating with good water resistance and weather resistance, which can be used to protect the substrate 21 from moisture intrusion and damage; the wear-resistant layer 25 is a hard coating with good wear resistance and corrosion resistance, which can prevent the substrate 21 from being damaged by scratches, friction and chemicals; the shielding coating 22 is composed of a composite material containing metal particles and has high electromagnetic shielding performance, which can effectively block the penetration of external electromagnetic fields and reduce interference; the suppression coating 23 contains absorbing materials and has the ability to absorb or attenuate external electromagnetic waves, thereby preventing interference with the substrate 21.

[0036] When in use, the module body 2 is first placed inside the shell 11, and the cover body 12 drives the connecting block 121 and the spring sheet 122 downward into the inner cavity of the connecting groove 112. The spring sheet 122 is squeezed and deformed by the inner wall of the connecting groove 112 until the spring sheet 122 moves to the positioning groove 113 and loses the squeezing force. The reset elastic force of the connecting groove 112 resets it to the inner cavity of the positioning groove 113, thereby realizing the connection between the shell 11 and the cover body 12. The module body 2 can be protected by the shell 11 and the cover body 12, and because the shell 11 and the cover body 12 are made of metal, they can preliminarily reflect external electromagnetic waves, thereby reducing interference. Moreover, when subjected to external collision, the buffer strip 13 can effectively buffer the impact force and prevent the module body 2 from directly colliding with external objects, thereby causing unstable connection and interference. During use, the wear-resistant layer 25 can improve the wear resistance and corrosion resistance of the substrate 21, and protect the surface of the substrate 21 from scratches, friction and chemical damage. At the same time, the waterproof layer 24 can effectively ensure that the substrate 21 is not invaded and damaged by moisture. The suppression coating 23 can effectively absorb or attenuate the ability of external electromagnetic waves, thereby reducing interference. The shielding coating 22 can effectively block the penetration of external electromagnetic fields and prevent interference, thereby improving the anti-interference ability of the substrate 21.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatic control through a controller.
