Fig. 1 is a perspective view of an improved network filter 100 according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of an improved network filter 100 according to an embodiment of the present invention.

As shown in fig. 1 to 2, the present embodiment discloses an improved network filter 100, and the improved network filter 100 includes a filter bottom case 10, a filter upper cover 20, and a sealing body 30. The filter bottom case 10 has a mounting cavity 11 that accommodates the electronic component 40.

After the existing bottom shell and the upper cover of the filter are assembled, the waterproof performance of the joint of the bottom shell and the upper cover of the filter is poor, so that the service life of the network filter is shortened.

In order to improve the waterproof performance of the improved network filter 100, the present embodiment adopts the following measures: the end face of the connection end of the filter bottom case 10 has an annular groove 12. The filter upper cover 20 comprises a cover body part 21 and a connecting part 22 which are connected, and the connecting part 22 is in clamping fit with the inner wall of the filter bottom shell 10. The sealing body 30 is inserted into the groove 12 and is interposed between the lid portion 21 and the groove bottom of the groove 12.

With the above scheme, the improved network filter 100 of the embodiment has the following beneficial effects: the sealing body 30 is inserted into the groove 12 and interposed between the cover body 21 and the bottom of the groove 12, so that the connection between the filter bottom case 10 and the filter upper cover 20 can be sealed, and the waterproof performance of the improved network filter 100 of the present embodiment is improved.

In addition, the sealing body 30 is inserted into the groove 12, so that the sealing body 30 is reliably mounted, and the sealing body 30 is not easy to fall off.

Fig. 3 is a partial enlarged view at I of fig. 2. As shown in fig. 2 and 3, preferably, three seals are formed between the seal body 30 and the groove bottom of the groove 12. Thereby improving the sealing effect between the sealing body 30 and the bottom of the groove 12.

Preferably, the face of the sealing body 30 facing the bottom of the groove has two cavities 31, so as to form the three seals described above. The cross-sectional shape of the cavity 31 is a semicircle, which has the advantages of convenient manufacture and simplified processing technology.

As shown in fig. 2 and 3, the surface of the sealing body 30 that is bonded to the lid portion 21 is preferably a curved surface 32. Preferably, a single seal is formed between the seal body 30 and the cover body portion 21. After the connecting portion 22 is engaged with the inner wall of the bottom housing 10, the cover portion 21 presses the curved surface 32. At this time, the lid 21 and the curved surface 32 are closely attached to form a seal, and the sealing body 30 and the groove bottom of the groove 12 are closely attached to form a seal. The sealing body 30 is deformed by the pressing of the lid body 21 and the groove bottom of the groove 12, and is closely attached to the side wall of the groove 12 to form a seal. The filter bottom case 10 and the filter upper cover 20 of the embodiment have good sealing effect at the joint, and can meet the use requirement. An improved network filter 100 of the present embodiment can be applied to an environment with high moisture.

Preferably, the sealing body 30 is attached to at least one side wall of the groove 12, thereby being beneficial to ensuring the sealing effect and further improving the sealing performance. Here, the sealing body 30 is attached to at least one side wall of the recess 12, which means that the sealing body 30 is attached to at least one side wall of the recess 12 in a natural state. Thereby, after the extrusion deformation, the sealing effect can be further ensured.

Preferably, the connecting portion 22 has two sets of catches 221, the two sets of catches 221 being distributed along the axial direction of the connecting portion 22. The clip 221 is snap-fitted to the inner wall of the bottom case 10 of the filter. The connection portion 22 of the present embodiment is conveniently connected to the bottom case 10 of the filter. The improved network filter 100 is suitable for occasions needing to disassemble and assemble the improved network filter 100.

Preferably, the cover portion 21 and the connecting portion 22 are integrally formed, for example, the cover portion 21 and the connecting portion 22 are integrally injection-molded, the forming method is simple, and the connection reliability between the cover portion 21 and the connecting portion 22 is good.
