Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a novel busbar connector. Background Technology

[0002] In medium and high voltage switchgear, busbar connectors are typically used to extend busbars. Busbar connectors must not only ensure reliable electrical connection of the busbars but also provide external insulation. Their performance directly affects the safety and reliability of the power transmission and distribution system.

[0003] Since a busbar circuit is typically tens or hundreds of meters long, while busbars can only be manufactured section by section, with a maximum length of six meters per section, they must be transported to the site and then connected using busbar connectors. In existing technologies, bus connectors are typically not connected by mutual plugging. However, this method makes it difficult to seal the connection points, resulting in poor overall sealing and the accumulation of dust inside the connector. Therefore, this invention proposes a novel bus connector to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel bus connector to solve the problems mentioned in the background art.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1 to 4This utility model provides a technical solution: a novel busbar connector, comprising: a connecting tube 1 sleeved on the surface of a conductor 10, which guides the sliding of the conductor 10; threaded grooves 2 are formed on both ends of the connecting tube 1; sliding grooves 3 are formed on both ends of the connecting tube 1, which limit the movement of the conductor 10; several oblique grooves 4 are formed on both ends of the connecting tube 1, which communicate with the sliding grooves 3; one end of a fixing post 5 is fixedly connected to a connecting post 6, and the two are integrated into one design. When the connecting post 6 rotates, the fixing post 5 rotates accordingly, thus fixing... The surface of column 5 is frosted to increase friction, which facilitates the rotation of the fixed column 5. The inner wall of the fixed column 5 is rotatably connected to several elastic plates 7 via protrusions. The elastic plates 7 are fixedly connected to each other. In its natural state, the elastic plates 7 are flat. The other end of the elastic plate 7 is fixedly connected to a fixing block 8. The fixing block 8 is arc-shaped, which facilitates the adaptation of the slide groove 3 and can also fix the wire 10. The elastic plates 7 are located inside the fixed column 5. The inner wall of the fixed column 5 is fixedly connected to a skeleton sealing ring 14, which can improve the overall sealing effect.

[0017] A threaded tube 12 is fixedly connected to the surface of the wire 10. The threaded tube 12 can protect the surface of the wire 10 from accidental damage. A limiting ring 11 is fixedly connected to one end of the threaded tube 12 near the connecting tube 1. The diameter of the limiting ring 11 is larger than the diameter of the inner wall of the connecting column 6. The limiting ring 11 can limit the movement of the connecting column 6 and the fixed column 5. At the same time, it can cooperate with the skeleton sealing ring 14 to improve the sealing effect at the connection. A sealing disc 13 is fixedly connected to the surface of the wire 10. The sealing disc 13 is made of rubber material to improve the sealing effect on the slide groove 3.

[0018] The inner wall of the connecting post 6 is threadedly connected to the surface of the threaded tube 12. The pitch and related parameters of the thread on the surface of the threaded tube 12 are the same as those of the thread groove 2. The inner wall of the fixing post 5 is in close contact with the limiting ring 11. The limiting ring 11 is in close contact with the skeleton sealing ring 14. At this time, the limiting ring 11 can squeeze the skeleton sealing ring 14 to form a sealing ring on the surface of the limiting ring 11, so that external moisture and dust cannot enter the fixing post 5. The wire 10 is slidably connected to the inner wall of the connecting tube 1. The sealing plate 13 is slidably connected to the sliding groove 3. When installation is required, the wire 10 can be slid into the sliding groove 3. The thread groove 2 on the surface of the connecting tube 1 is threadedly connected to the fixing post 5. The length of the fixing post 5 is greater than the length of the connecting post 6. When the fixing post 5 rotates and begins to be threadedly connected to the thread groove 2, the connecting post 6 also rotates at the same time and begins to be threadedly connected to the threaded tube 12.

[0019] The surface of the elastic plate 7 is slidably connected to the inclined groove 4. The inner arc surface of the fixing block 8 contacts the surface of the wire 10. The side of the fixing block 8 is arc-shaped, which facilitates sliding. The surface of the fixing block 8 is in close contact with the sealing disc 13. The fixing block 8 can fix the sealing disc 13 and also clamp the wire 10. The surface of the connecting pipe 1 is wrapped with insulating tape 9. The two ends of the insulating tape 9 are bonded to the surfaces of the two fixing posts 5. The insulating tape 9 can protect and isolate the connection between the connecting pipe 1 and the fixing posts 5, so that external moisture and dust cannot enter the connecting pipe 1. During the threaded connection between the threaded pipe 12 and the connecting post 6, the fixing block 8 will first contact the inclined groove 4 and move along the inclined groove 4. The fixing block 8 causes the elastic plate 7 to gradually bend and fit the inclined groove 4 until the fixing block 8 is in close contact with the sealing disc 13. Then the insulating tape 9 can be wrapped.

[0020] Slide the wire 10 along the groove 3, then first insert the fixing block 8 into the inclined groove 4 slightly, and then rotate the fixing posts 5 on both sides. At this time, under the action of the threaded groove 2 and the threaded tube 12, the connection between the fixing post 5 and the connecting tube 1 gradually tightens. During this process, the fixing block 8 is gradually inserted into the inclined groove 4 until the fixing block 8 is in close contact with the sealing plate 13. At this time, the limiting ring 11 and the skeleton sealing ring 14 are in close sealing contact. Then, the insulating tape 9 can be wrapped to isolate the connection. At this time, the connecting tube 1 is isolated from the outside, so that the whole interior is sealed and isolated, so that external moisture and dust will not come into contact with the connection of the wire 10.

[0021] When this device is in operation, the rotation of the fixing column 5 and the connecting column 6 can seal both ends of the connecting pipe 1. At the same time, the connection of the wire 10 can be fixed by the limiting ring 11. The sliding of the fixing block 8 can squeeze the sealing plate 13, thereby sealing the connection of the wire 10. Then, the connection between the fixing column 5 and the connecting pipe 1 can be isolated by the insulating tape 9. The whole device can effectively seal and isolate, thereby preventing external moisture and dust from contacting the connection of the wire 10, thus providing protection.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
