Description

Technical Field

[0001] The utility model belongs to the technical field of power accessories, in particular to a soft rubber insulating busbar joint. Background Art

[0002] Busbar is one of the most common accessories in power accessories. It is mainly used to collect and distribute electricity. In order to ensure the safety of the environment in which it is located, a layer of insulating material needs to be laid on the outer wall of the busbar, so it is also called an insulating busbar. The most common type of insulating busbar is the soft rubber insulating busbar, which is named because the insulating material laid on its outer wall is soft rubber. At the same time, it also needs to be used with a busbar connector. The busbar interface is used to connect two busbars or a busbar to a device connector.

[0003] A Chinese patent application (or patent) with publication number CN220042964U discloses an insulated busbar joint kit, including a wrapping sleeve, the inner sides of which are respectively fixedly connected with a first sealing sheet and a second sealing sheet, and the outer side of the wrapping sleeve is fixedly connected with a fixing belt, the inner side of the fixing belt is fixedly connected with a sealing block, and the inner side of the fixing belt is fixedly connected with a first Velcro, a groove is provided on the outer side of the wrapping sleeve, the sealing block is snap-fitted with the groove, the outer side of the wrapping sleeve is fixedly connected with a second Velcro, the first Velcro and the second Velcro are adhered to each other, the first sealing sheet and the second sealing sheet are fixedly connected with a magnetic pad on one side close to each other, the two magnetic pads are magnetically connected, and the first sealing sheet and the second sealing sheet are symmetrically provided with connecting grooves. Through the above structure, the disassembly and assembly between the busbar and the joint kit can be facilitated, which greatly improves the installation efficiency of the staff.

[0004] The above-mentioned insulating busbar joint kit has a fixing belt on its wrapping sleeve, and a first Velcro and a second Velcro are respectively provided at both ends of the fixing belt. The fixing belt can be tied to the end of the insulating busbar by mutual adhesion between the two Velcros. The adhesion between the Velcros is low and the binding effect brought by them is extremely limited, which easily causes the problem of the fixing belt detaching from the insulating busbar; and, the two sealing sheets thereon are inlaid with magnetic pads, and the two sealing sheets are brought close to each other by the adsorption force of the magnetic pads to improve the sealing after the connection between the wrapping sleeve and the insulating busbar. However, because the two sealing sheets are also provided with a connecting groove connecting the insulating busbar and other busbars, the groove is exposed and no sealing mechanism is provided thereon, so the connection between the groove and the other busbars only relies on snap-fit, and thus the sealing is still low. For this reason, we provide a soft rubber insulating busbar joint to solve the above-mentioned problems. Utility Model Content

Specific Embodiment 1

[0032] Please refer to Figures 1-5 , the present invention is a soft rubber - insulated busbar joint, including a joint ring 1. Sealing assemblies 4 are provided at both ends of the joint ring 1. The sealing assemblies 4 are embedded in the sealing grooves 102 of the joint ring 1, and the second spring 403 in the sealing assemblies 4 can push the sealing ring 401 to abut against the outer wall of the fitting sleeve 201 on the assembly ring 2, improving the sealing performance between the two when the assembly ring 2 is screwed onto the joint ring 1 in a spiral manner.

[0033] Specifically, connecting sleeves 101 for threaded connection with the fitting sleeves 201 on the outer wall of the assembly ring 2 are welded at both ends of the joint ring 1. And on the outer wall of the shaft end of the joint ring 1 inside the connecting sleeve 101, a sealing groove 102 for accommodating and installing the sealing assembly 4 is provided, and an installation hole 103 for accommodating the second spring 403 is further provided on the inner wall of the sealing groove 102.

[0034] Furthermore, the sealing assembly 4 includes a sealing ring 401, a connecting sleeve 402 and a spring 2 403, wherein one end of the spring 2 403 is connected to the sealing ring 401 through the connecting sleeve 402, and the other end of the spring 2 403 is bonded to the mounting hole 103, and the outer wall of the sealing ring 401 is also abutted against the axial end of the mating screw sleeve 201.

[0035] The operation process of this embodiment is: align the matching screw sleeve 201 on the assembly ring 2 with the connecting screw sleeve 101 on the joint ring 1, and then rotate the assembly ring 2 to make the matching screw sleeve 201 thereon rotate into the connecting screw sleeve 101, thereby completing the installation between the joint ring 1 and the assembly ring 2. At the same time, because the matching screw sleeve 201 gradually penetrates into the joint ring 1, the assembly ring 2 also gradually approaches the sealing assembly 4 and abuts against the sealing ring 401 thereon, and the spring 2 403 on the sealing ring 401 can abut against the sealing ring 401, ensuring that the sealing ring 401 is fully in contact with the outer wall of the axial end of the matching screw sleeve 201. Specific embodiment 2

[0037] See also Figure 6 On the basis of the specific embodiment 1, an assembly ring 2 and a rubber air ring 206 on its inner wall are also provided. The rubber air ring 206 is inflated by blowing air through an air nozzle 207. After the rubber air ring 206 is inflated, it gradually adheres to the outer wall of the soft rubber insulating busbar to ensure the airtightness between the two.

[0038] Specifically, a bonding groove 202 is provided on the inner wall of the assembly ring 2 near the shaft end, one side of the bonding plate 205 is bonded to the bonding groove 202 , and the other side is bonded to the rubber air ring 206 .

A pull ring 302 is inserted through the top of the sliding rod 301.

[0045] The operation process of this embodiment is as follows: Hold the pull ring 302 and pull the sliding rod 301 outwards. The positioning plate 303 on the sliding rod 301 will abut against the first spring 304 and compress it. At this time, the contact plate 305 will move outwards, exposing a larger space for installing and accommodating the soft rubber insulating busbar in the assembly ring 2. Then, insert the soft rubber insulating busbar into the assembly ring 2, and then release the pull ring 302. At this time, the first spring 304 is not stressed, and it will support between the two clamping plates 204 and push the positioning plate 303 downwards, that is, the sliding rod 301 moves downwards, and then the contact plate 305 at its bottom will abut against the outer wall of the soft rubber insulating busbar.
