[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figure 1-5 The present invention relates to a water-proof busbar trunking, comprising a busbar trunking housing 1, wherein a busbar array 11 is fixedly disposed inside the busbar trunking housing 1, and connecting pieces 12 are symmetrically fixedly disposed at both ends of the busbar trunking housing 1, and connecting holes 13 are provided on the connecting pieces 12; in use, different busbar trunking housings 1 are connected together by passing bolts through the connecting holes 13 on the connecting pieces 12, and the corresponding busbar arrays 11 are then docked and fixed.

[0023] However, during actual use, when busbar trunking needs to extend from one building to another, the connection point between the two busbar trunking sections is exposed in the air without any overhead cover for rain protection. Therefore, it is necessary to improve the waterproof performance of the connection point to ensure good performance. Thus, a connecting sleeve 2 is installed between adjacent busbar trunking shells 1. An outer waterproof frame 3, a middle waterproof frame 4, and an inner waterproof frame 5 are fixedly installed at one end of the busbar trunking shell 1. The outer waterproof frame 3, the middle waterproof frame 4, and the inner waterproof frame 5 extend sequentially from the end of the busbar trunking shell 1 furthest from the connecting sleeve 2 towards... Arranged near one end of the connecting sleeve 2; an outer groove 6 and an inner ring 7 are fixedly installed inside the end of the connecting sleeve 2 near the busbar housing 1; the outer waterproof frame 3 is used in conjunction with the outer groove 6, the middle waterproof frame 4 is used in conjunction with the connecting sleeve 2, and the inner waterproof frame 5 is used in conjunction with the inner ring 7. Sealing gaskets 8 are provided at the junction of the outer waterproof frame 3 and the outer groove 6, and at the junction of the inner waterproof frame 5 and the inner ring 7. Multiple fixing holes 9 are opened on the outer wall of the connecting sleeve 2 and the outer waterproof frame 3. The fixing holes 9 on the connecting sleeve 2 and the fixing holes 9 on the outer waterproof frame 3 are fixed by screws 10.

[0024] With this design, during installation, the connecting sleeve 2 is first fitted onto the outside of one of the busbar trunking housings 1, and the connecting sleeve 2 is moved so that the outer groove 6 on the connecting sleeve 2 abuts against the outer waterproof frame 3 on the busbar trunking housing 1. Then, the connecting sleeve 2 and the outer waterproof frame 3 are fixed together with the help of tools and screws 10. Then, the other busbar trunking housing 1 can be installed in the same way. In this way, the outer waterproof frame 3 and its sealing gasket 8 achieve a primary waterproofing effect, the middle waterproof frame 4 prevents rainwater penetration and achieves a secondary waterproofing effect, and finally the inner waterproof frame 5 and its sealing gasket 8 achieve a tertiary waterproofing effect.

[0025] It should be noted that the connecting sleeve 2 can be made of rigid material; or both ends can be made of rigid material and the middle part of flexible material, in order to ensure connection strength and sealing and waterproof effect, and at the same time facilitate docking of different busbar housings 1.

[0026] Specifically, the outer waterproof frame 3 includes an outer frame portion 14 and an inner frame portion 15 that are integrated together. The size of the outer frame portion 14 is larger than the corresponding size of the inner frame portion 15, and the size of the inner frame portion 15 is equal to the corresponding size of the middle waterproof frame 4 and the corresponding size of the inner waterproof frame 5. One sealing gasket 8 is fitted onto the inner frame portion 15, and the other sealing gasket 8 is fitted onto the busbar housing 1 and located on the inner waterproof frame 5 on the side near the connecting sleeve 2.

[0027] Specifically, there are two intermediate waterproof frames 4, which are located between the outer waterproof frame 3 and the inner waterproof frame 5; this design provides a better water-blocking effect through multiple layers of secondary waterproofing.

[0028] Furthermore, the inner bottom wall of the connecting sleeve 2 is provided with multiple water-permeable holes 16. These holes 16 are located between the outer groove 6 and the inner ring 7, and are distributed along the width of the connecting sleeve 2 between the outer waterproof frame 3 and the middle waterproof frame 4, between the middle waterproof frames 4 and 4, and between the middle waterproof frame 4 and the inner waterproof frame 5. With this design, even if the sealing performance of the busbar trunking decreases after a long period of use, and rainwater enters between the outer waterproof frame 3 and the middle waterproof frame 4, the water-permeable holes 16 will prevent the accumulation of rainwater and achieve the effect of preventing water accumulation.

[0029] Furthermore, a plastic sealing sleeve 17 is heat-sealed at the connection between the busbar trunking housing 1 and the connecting sleeve 2. One end of the plastic sealing sleeve 17 is fixedly fitted onto the busbar trunking housing 1, and the other end of the plastic sealing sleeve 17 is fixedly fitted onto the connecting sleeve 2. With this design, during installation, the plastic sealing sleeve 17 is fitted onto the connection between the two and then heated. After being heated, the plastic sealing sleeve 17 shrinks and fits onto the connection between the two, further improving the waterproof effect.
