[0028] Example 1

[0029] Combination Figures 1 to 3 As shown, the waterproof device of this utility model is schematically displayed, including a box body 10, a cover body 20, and a cable 30.

[0030] like Figure 2The cover 20 is provided with a wire-passing component 21 and a mounting component 22. The cable 30 passes through the wire-passing component 21 and the two are sealed together, that is, the outer wall of the cable 30 is tightly fitted with the inner wall of the wire-passing component 21 to prevent moisture from passing through. The wire-passing component 21 has a number of wire-passing holes 211, the number of which is the same as the number of cables 30. Each cable 30 is connected to one wire-passing hole 211, and the inner wall of the wire-passing hole 211 is tightly fitted with the outer wall of the cable 30. The mounting component 22 is provided with a bracket 221 for mounting a circuit board 40. The circuit board 40 is electrically connected to one end of the cable 30, and the other end of the cable 30 can be connected to other external devices. The bracket 221 has a number of mounting slots 2211, which can be used to mount the circuit board 40 to the mounting slots 2211 using existing screws or bolts. The mounting slots 2211 can be designed to accommodate circuit boards 40 of different sizes. When the cable 30 is subjected to external tension, the cable 30 transmits the tension to the wire threading component 21, the cover 20, the mounting component 22, and the bracket 221. Therefore, the tension on the cable 30 will simultaneously pull the wire threading component 21, the cover 20, the mounting component 22, and the bracket 221. This can prevent the cable 30 from detaching from the circuit board 40 due to external tension.

[0031] like Figure 3 The box 10 has a cavity 11 and an opening 12 that connects the cavity 11 to the outside. The bracket 221 passes through the opening 12 and is located inside the cavity 11. The cover 20 covers the opening 12. The cover 20 and the box 10 are connected to prevent external moisture from entering the cavity 11. The cavity 11 can accommodate the bracket 221 and the circuit board 40 on the bracket 221. When the cable 30 is subjected to external tension, the tension will not be transmitted to the connection between the cover 20 and the box 10, which can prevent the cover 20 and the box 10 from accidentally detaching and causing waterproof failure.

[0032] Specifically, the cover 20 is provided with a surrounding mounting groove 23, and a sealing ring 231 is provided within the mounting groove 23. The sealing ring 231 can be made of existing rubber or silicone materials. The end face around the opening 12 of the box 10 abuts against the sealing ring 231, and the end face of the box 10 abuts against and compresses the sealing ring 231, improving the sealing performance at the connection between the cover 20 and the box 10. A plurality of first connecting holes are uniformly arranged around the cover 20, and a plurality of second connecting holes are uniformly arranged around the end of the box 10. Existing screws or bolts can be used to pass through the first connecting holes and the second connecting holes to fasten the cover 20 and the box 10 and prevent them from separating.

[0033] The cover 20 is provided with an annular extension 24, which penetrates the opening 12 of the box 10. A gap 241 is provided between the outer side of the extension 24 and the inner wall of the box 10. When sealant is injected into the cavity 11, the sealant can penetrate into the gap 241 to improve the sealing performance of the connection between the cover 20 and the box 10.

[0034] Furthermore, the box body 10 has a front end 10a and a rear end 10b. The opening 12 is located at the front end 10a of the box body 10. On both sides of the end face of the rear end 10b of the box body 10, there are glue-filling holes 13 and vent holes 14. Both the glue-filling holes 13 and the vent holes 14 are used to connect the cavity 11 with the outside. The glue-filling holes 13 are used to fill the cavity 11 with sealant. At the same time, the vent holes 14 can discharge the air in the cavity 11 to the outside so that the glue filling is smooth. The box body 10 is provided with a glue-filling tube 15 arranged from its tail end 10b to its head end 10a, one end of which is connected to the glue-filling hole 13; and / or, the box body 10 is provided with an exhaust pipe 16 arranged from its tail end 10b to its head end 10a, one end of which is connected to the exhaust hole 14. The glue-filling tube 15 is provided so that the sealant is closer to the connection between the cover 20 and the box body 10 during glue filling. The end of the glue-filling tube 15 is positioned opposite to the extension 24, which makes it easier for the sealant to penetrate into the gap 241 between the extension 24 and the box body 10. During the process of filling the sealant, the filling hole 13 and the vent hole 14 face upwards. The filled sealant will first contact the first end 10a of the box body 10. As the sealant in the cavity 11 of the box body 10 gradually increases until it blocks the vent pipe 16, the air can no longer be discharged. Therefore, no more sealant can be filled into the cavity 11. The circuit board 40 is a certain distance away from the first end 10a of the box body 10, which can prevent the sealant from completely covering the circuit board 40 and causing adverse effects.

[0035] In this embodiment, the box body 10 is made of transparent material, allowing installation and maintenance personnel to observe the glue filling process inside the cavity 11 through the box body 10. The outer wall of the box body 10 is provided with intersecting first reinforcing ribs 17 and second reinforcing ribs 18. There are multiple first reinforcing ribs 17, and these ribs are parallel to each other. Similarly, there are multiple second reinforcing ribs 18, and these ribs are parallel to each other. In this embodiment, the first reinforcing ribs 17 and second reinforcing ribs 18 are perpendicular to each other. The first reinforcing ribs 17 and second reinforcing ribs 18 can improve the rigidity and strength of the box body 10 to withstand greater water pressure.

[0036] Example 2

[0037] like Figure 4This embodiment discloses a display device 1, such as a display module 100 and the aforementioned waterproof device. One end of the cable 30 passes through the wiring component 21 and is electrically connected to the circuit board 40 inside the housing 10. The other end of the cable 30 is electrically connected to the display module 100, thereby realizing signal transmission between the circuit board 40 and the display module 100.

[0038] In summary, the cover 20 is provided with a wiring component 21 and a mounting component 22. The cable 30 can be passed through the wiring component 21, and the cable 30 and the wiring component 21 are sealed together to prevent moisture intrusion. The mounting component 22 is provided with a bracket 221, and the circuit board 40 can be mounted on the bracket 221. The bracket 221 passes through the opening 12 of the box 10 into the cavity 11. The cover 20 covers the opening 12 of the box 10 to form a closed space in the cavity 11. When the cable 30 is pulled by an external force, the cable 30 transmits the tension to the wiring component 21 and the cover 20. Since the circuit board 40 is mounted on the bracket 221 on the cover 20, the tension transmitted by the cable 30 will not act on the connection between the cover 20 and the box 10, thus preventing the cover 20 and the box 10 from accidentally separating and causing waterproofing failure.
