Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a waterproof connection device and a display device. Background Technology

[0002] Waterproof displays are widely used in various fields such as outdoor advertising and stage construction. These applications all place stringent requirements on the waterproof performance of the displays. The connections between the cables of the displays generally use aviation connectors, where the aviation connector at one end of one cable interlocks with the aviation connector at the other end of the cable to transmit electrical signals and / or power. To achieve a waterproof seal, existing aviation connectors typically rely solely on their own rubber rings for sealing.

[0003] However, the material properties and structural design of the rubber ring itself limit its waterproof performance, making it difficult to meet the needs of high waterproof rating scenarios. Under long-term use or harsh environments, the rubber ring is prone to aging and deformation, further reducing its sealing effect. On the other hand, when the two aviation plugs are not fully inserted during installation or use, the rubber ring cannot fully perform its sealing function, which will lead to an increase in the plug mating gap, resulting in a significant risk of water leakage and seriously affecting the waterproof reliability of the connection.

[0039] Example 1

[0040] Combination Figures 1 to 9 As shown, the waterproof connection device 1 of this utility model is schematically displayed, including a first cable 10, a second cable 20 and a sealing sleeve 30. The sealing sleeve 30 is a cylindrical structure with its two ends connected.

[0041] Combination Figure 4 and Figure 5The first cable 10 has a first connector 11 at its end and a first wire core 12 passing through the first connector 11. That is, the end of the first cable 10 is provided with a first connector 11 for connecting with other structures, and the first wire core 12 in the first cable 10 passes through the first connector 11. Similarly, the second cable 20 has a second connector 21 at its end and a second wire core 22 passing through the second connector 21. That is, the end of the second cable 20 is provided with a second connector 21 for connecting with other structures, and the second wire core 22 in the second cable 20 passes through the second connector 21.

[0042] like Figure 6 The two ends of the sealing sleeve 30 are respectively connected to the first connector 11 and the second connector 21. The end of the sealing sleeve 30 can be sleeved on the first connector 11 (or the second connector 21) or abutted against the first connector 11 (or the second connector 21). The first wire core 12 and the second wire core 22 are connected, and the connection point between them is located inside the sealing sleeve 30. The sealing sleeve 30 is filled with sealant 40. The sealant 40 contacts the first connector 11, the first wire core 12, the inner wall of the sealing sleeve 30, the second wire core 22, and the second connector 21. The sealant 40 not only prevents moisture from corroding the connection point of the first wire core 12 and the second wire core 22 and causing a short circuit, but also improves the connection strength between the first cable 10 and the second cable 20, preventing the first cable 10 and the second cable 20 from being pulled apart by external forces.

[0043] In this embodiment, there are multiple first wire cores 12 and multiple second wire cores 22, and the number of the two is the same. Each first wire core 12 corresponds to one second wire core 22.

[0044] The first connector 11 is interference-fitted with the first cable 10, and the second connector 21 is interference-fitted with the second cable 20. The first connector 11 and the second connector 21 can be made of existing materials such as rubber or plastic. The first connector 11 is fitted onto the end of the first cable 10, and the second connector 21 is fitted onto the end of the second cable 20. Pressure is applied to the first connector 11 using crimping pliers to crimp it to the end of the first cable 10. Similarly, pressure is applied to the second connector 21 using crimping pliers to crimp it to the end of the second cable 20. This crimping connection improves the tightness of the connection between the first connector 11 (second connector 21) and the first cable 10 (second cable 20), and also enhances the waterproof performance at the connection point.

[0045] Furthermore, one end of the first connector 11 is crimped to the first cable 10, and the other end of the first connector 11 is provided with a first connecting cavity 113. The first wire core 12 passes through the first connecting cavity 113, so a gap is left between the inner wall surface of the first connecting cavity 113 and the first wire core 12. The first connecting cavity 113 communicates with the interior of the sealing sleeve 30, and the first connecting cavity 113 is filled with sealant 40. The sealant 40 extends into the first connecting cavity 113, increasing the bonding area between the sealant 40 and the first connector 11, and can further improve the connection strength between the sealant 40 and the first connector 11. Similarly, one end of the second connector 21 is crimped to the second cable 20, and the other end of the second connector 21 is provided with a second connecting cavity 213. The second wire core 22 passes through the second connecting cavity 213, and a gap is left between the inner wall surface of the second connecting cavity 213 and the second wire core 22. The second connecting cavity 213 is connected to the interior of the sealing sleeve 30. The second connecting cavity 213 is filled with sealant 40, and the sealant 40 extends into the second connecting cavity 213 to increase the bonding area between the sealant 40 and the second connector 21, thereby further improving the connection strength between the sealant 40 and the second connector 21.

[0046] Of course, when there are multiple first cores 12 and multiple second cores 22, the sealant 40 will also extend between adjacent first cores 12 / adjacent second cores 22, which can be combined with Figure 7 As shown, in addition to sealing and waterproofing, it can also fix each first core 12 and each second core 22 to prevent multiple first cores 12 (multiple second cores 22) from tangling and curling abnormally.

[0047] Combination Figure 4 and Figure 9 As shown, to facilitate the assembly of the sealing sleeve 30, the sealing sleeve 30 includes two connected sealing shells 31. The cross-section of the sealing shell 31 is U-shaped. The two sealing shells 31 are interlocked to form a cylindrical sealing sleeve 30. Therefore, after connecting the first wire core 12 and the second wire core 22, the two sealing shells 31 can be interlocked from both sides of the connection between the first wire core 12 and the second wire core 22. Each end of the sealing shell 31 is provided with a connecting post 311 and a connecting hole 312. The connecting post 311 of one sealing shell 31 is embedded in the connecting hole 312 of the other sealing shell 31. The connecting post 311 and the connecting hole 312 can be an interference fit to temporarily fix the two opposing sealing shells 31 before the sealant 40 is injected.

[0048] To further improve the connection stability of the first cable 10 and the second cable 20, the waterproof connection device 1 also includes a movable first adjusting component 50 and a second adjusting component 60, such as... Figures 6 to 8The first adjusting component 50 and the second adjusting component 60 can move towards each other or away from each other. The first connector 11 is provided with a first limiting ring 111, and the second connector 21 is provided with a second limiting ring 211. The first adjusting component 50 is slidably abutted against the first limiting ring 111, and the second adjusting component 60 is slidably abutted against the second limiting ring 211. Adjusting the first adjusting component 50 and the second adjusting component 60 and reducing the distance between them can force the first connector 11 and the second connector 21 to move towards each other. The first connector 11 and the second connector 21 clamp the sealing sleeve 30. Furthermore, the waterproof connection device 1 also includes a connecting sleeve 70. The first connector 11 is provided with a plurality of first sealing rings 112, and the second connector 21 is provided with a plurality of second sealing rings 212. The two ends of the connecting sleeve 70 are respectively fitted onto part / all of the first connector 11 and part / all of the second connector 21. The first sealing rings 112 and the second sealing rings 212 abut against the inner wall surface of the connecting sleeve 70. The first adjusting component 50 is slidably abutted against one end of the connecting sleeve 70, and the second adjusting component 60 is slidably abutted against the other end of the connecting sleeve 70. The connecting sleeve 70 can be fixed by the first adjusting component 50 and the second adjusting component 60. The connection assembly formed by the combination of the first adjusting component 50, the second adjusting component 60 and the connecting sleeve 70 occupies less space in the radial direction of the first cable 10 (or the second cable 20) than the existing aviation plug, and has wider adaptability.

[0049] Example 2

[0050] like Figure 3 , Figure 5 and Figure 8 The difference between this embodiment and embodiment 1 is that the end of the first wire core 12 is provided with a first terminal 121, and the end of the second wire core 22 is provided with a second terminal 221. The first terminal 121 and the second terminal 221 are plugged into each other, and the first wire core 12 and the second wire core 22 are connected through the first terminal 121 and the second terminal 221. The first terminal 121 and the second terminal 221 can be quickly plugged in to improve assembly efficiency.

[0051] Example 3

[0052] like Figure 2 , Figure 4 and Figure 7The difference between this embodiment and Embodiment 1 is that the waterproof connection device 1 further includes a wiring sleeve 80. One end of the wiring sleeve 80 is fitted onto the end of the first wire core 12, and the other end of the wiring sleeve 80 is fitted onto the end of the second wire core 22. By applying pressure to the end of the wiring sleeve 80 with existing wire crimping pliers, the end of the wiring sleeve 80 is forced to deform, and the end of the wiring sleeve 80 can then be tightly connected to the end of the first wire core 12 (or the second wire core 22). The first wire core 12 and the second wire core 22 are electrically connected through the wiring sleeve 80. The wiring sleeve 80 is preferably a sleeve made of a conductive material, such as metal or graphite.

[0053] Example 4

[0054] Combination Figure 10 As shown, in order to solve the same technical problem, this embodiment provides a display device 100, including a display module 2, a display control box 3, and a waterproof connection device 1 as described above. A first cable 10 is connected to the display module 2, and a second cable 20 is connected to the display control box 3. The waterproof connection device 1 can improve the connection strength of the first cable 10 and the second cable 20, and also improve the waterproof performance.

[0055] In summary, the first cable 10 has a first connector 11 at its end, and the second cable 20 has a second connector 21 at its end. The first connector 11 has a first wire core 12 inserted through it, and the second connector 21 has a second wire core 22 inserted through it. The first wire core 12 and the second wire core 22 are connected to achieve signal / power transmission. A sealing sleeve 30 is fitted onto the connection between the first wire core 12 and the second wire core 22. The two ends of the sealing sleeve 30 are respectively connected to the first connector 11 and the second connector 21. The sealing sleeve 30 is filled with sealant 40, which completely covers the connection between the first wire core 12 and the second wire core 22, preventing moisture erosion. The sealant 40 can also bond the sealing sleeve 30, the first connector 11, the second connector 21, the first wire core 12, and the second wire core 22 together, improving the connection strength at the connection between the first cable 10 and the second cable 20.
