Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1 to 6 In this embodiment of the present invention, a waterproof busbar trunking 100 includes: two busbar trunking bodies 10 and a busbar trunking body connector 20 for connecting the two busbar trunking bodies 10. Each busbar trunking body 10 includes: a trunking housing 11 and a plurality of conductive bars 12. The conductive bars 12 are mounted to the trunking housing 11 and are exposed at both ends of the trunking housing 11. The length of the conductive bars 12 is greater than the length of the trunking housing 11, and both ends of the conductive bars 12 are exposed at both ends of the trunking housing 11.
[0028] The busbar trunking main connector 20 includes two connecting side plates (not shown) and several insulating partitions 22 disposed between the two connecting side plates. The insulating partitions 22 separate two adjacent conductive bars 12. By tightening bolts, the two connecting side plates are pressed together, bringing them closer together, thereby clamping the conductive bars 12 with the insulating partitions 22. The insulating partitions 22 are provided with conductive plates 23 for electrically connecting the two busbar trunking main bodies 10. Bolts passing through the connecting side plates, the insulating partitions 22, and the conductive plates 23 on the insulating partitions 22 clamp the conductive bars 12, thereby causing the conductive plates 23 to adhere to the conductive bars 12.
[0029] In a preferred embodiment, the outer periphery of the insulating partition 22 is provided with an insulating rubber sleeve 24. The insulating rubber sleeves 24 of two adjacent insulating partitions 22 cover the ends of the conductive busbar 12 and the conductive sheet 23. The ends of the conductive busbar 12 and the conductive sheet 23 are enclosed in the space between the two insulating rubber sleeves 24, or in other words, enclosed between the two insulating partitions 22.
[0030] The insulating rubber sleeve 24 has protrusions 241 formed on it. When the insulating rubber sleeve 24 is compressed, the protrusions 241 seal the gaps at both ends of the conductive sheet 23 in width. (Reference) Figure 6The insulating rubber sleeve 24 deforms after compression, adhering to the conductive sheet 23, and the two insulating rubber sleeves 24 contact each other on the outer side of the conductive busbar 12. Without the protrusion 241, a triangular perforated area would be created at the end of the conductive busbar 12 in the width direction due to the deformation characteristics of the insulating rubber sleeve 24 itself, affecting the isolation and sealing effect. By providing the protrusion 241 on the insulating rubber sleeve 24, the protrusion 241 fills the triangular perforated area as the insulating rubber sleeve 24 deforms under compression, achieving the isolation and sealing effect.
[0031] An insulating material layer is provided on the portion of the conductive busbar 12 that is exposed outside the cable tray housing 11 and is not covered by the insulating rubber sleeve 24.
[0032] In one specific implementation, an insulating material layer is formed on the conductive busbar 12 by wrapping insulating tape around it.
[0033] As an optional implementation, the insulating material layer is an insulating material formed by coating or impregnation.
[0034] In one specific implementation, the inside of the cable tray housing 11 is sealed by potting adhesive.
[0035] In one specific implementation, the insulating rubber sleeve 24 has a rubber groove. The outer periphery of the insulating partition 22 is inserted into the rubber groove. The rubber groove is an annular groove. The insulating rubber sleeve 24 is annular and its cross-section is U-shaped.
[0036] In a preferred embodiment, there are eight protrusions 241. Four protrusions 241 are provided on each side of the insulating rubber sleeve 24. That is, the triangular perforated areas at both ends of the conductive busbar 12 in the width direction are jointly closed by the protrusions 241 on the two insulating rubber sleeves 24.
[0037] As an optional implementation, the plurality of protrusions 241 formed on the insulating rubber sleeve 24 are located on the same side of the insulating rubber sleeve 24. Specifically, there are four protrusions. The four protrusions 241 are located on the same side of the insulating rubber sleeve 24. That is, the triangular perforated areas at both ends in the width direction of the conductive busbar are closed by the protrusions on a single insulating rubber sleeve.
[0038] As an optional implementation, several protrusions can be set on one side to correspond to a single gap, thereby closing the gap. Similarly, for the method of setting protrusions on both sides, several protrusions on one side can also correspond to a single gap to close the gap.
[0039] In a preferred embodiment, the insulating partition 22 has a central through hole 221. The wall of the central through hole 221 protrudes outward to form a post ring 222. The post ring 222 passes through the bolt through hole on the conductive sheet 23. The post ring 222 can achieve isolation between the conductive sheet 23 and the bolt.
[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
