Abstract

This utility model provides a corner structure for a high-protection busbar trunking, including a bent busbar trunking and a protective pressure plate. Multiple aluminum alloy partitions are welded inside the bent busbar trunking, with arc-shaped grooves formed between them. Arc-shaped rubber sheets are adhered to each of these arc-shaped grooves using waterproof adhesive. The protective pressure plate is fitted to the inner side of the bent busbar trunking and abuts against the multiple aluminum alloy partitions. Multiple dovetail grooves are provided on the rear side of the protective pressure plate. This design solves the problem that the sealing rings of the original busbar trunking bolts, which use a spliced ​​structure, are prone to increased gaps due to vibration or aging, leading to sealing failure and requiring improved protection. This utility model adopts a multi-layered protective structure, effectively mitigating the aging of the conductors at the busbar trunking due to environmental factors.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a corner structure for a high-protection busbar trunking, including a bent busbar trunking 1 and a protective pressure plate 5. Multiple aluminum alloy partition plates 4 are welded inside the bent busbar trunking 1, and the gaps between the multiple aluminum alloy partition plates 4 form arc-shaped grooves. Arc-shaped rubber sheets 3 are uniformly adhered to the multiple arc-shaped grooves using waterproof adhesive. The protective pressure plate 5 is attached to the inner side of the bent busbar trunking 1 and abuts against the multiple aluminum alloy partition plates 4. Multiple dovetail grooves 9 are opened on the rear side of the protective pressure plate 5, and rubber dovetail strips 10 are inserted into the multiple dovetail grooves 9. Arc-shaped rubber strips 10 are integrally provided on the rear side of the multiple rubber dovetail strips 10. Item 8, the front end of the protective pressure plate 5 is equipped with multiple return springs 7, the front end of the outer side of the bent busbar trough 1 is staggered with multiple hand-tightening screws 12, the front end of the inner side of the bent busbar trough 1 is fixed with a ceramic cover plate 11 by multiple hand-tightening screws 12, the front end of the ceramic cover plate 11 is embedded with multiple embedded nuts 14, each of the multiple embedded nuts 14 is threaded with threaded screw blocks 15, and the rear end of each of the multiple threaded screw blocks 15 is equipped with a spring push plate 16. This design solves the problem that the original busbar trough bolts with spliced ​​structure of sealing rubber rings are prone to increased gaps due to vibration or aging, resulting in sealing failure and the need to improve the protection effect.

[0020] As the first embodiment of this utility model: multiple positioning posts 6 are welded to the front ends of both the outermost aluminum alloy partition plate 4 and the innermost aluminum alloy partition plate 4. Cylindrical positioning grooves are opened around the front end of the protective pressure plate 5, and multiple positioning posts 6 are respectively inserted into multiple cylindrical positioning grooves. By adding multiple positioning posts 6 and inserting them into multiple cylindrical positioning grooves, it is easy for the protective pressure plate 5 to fit against the inner side of the bent busbar groove 1 and accurately abut against multiple aluminum alloy partition plates 4.

[0021] Multiple arc-shaped rubber strips 8 are respectively inserted into multiple arc-shaped grooves, and the multiple arc-shaped rubber strips 8 are respectively positioned in front of multiple arc-shaped rubber sheets 3. By adding multiple arc-shaped rubber strips 8 and inserting them into multiple arc-shaped grooves, they can work together with multiple arc-shaped rubber sheets 3 to shield and protect the inserted wires. Multiple metal support pieces 13 are adhered to the inner side of the ceramic cover plate 11. By adding multiple metal support pieces 13, the support strength of the ceramic cover plate 11 can be improved. Multiple spring pushers 16 abut against multiple return springs 7 respectively. By adding multiple spring pushers 16 and abutting against multiple return springs 7 respectively, the multiple return springs 7 can be forced to press tightly against the protective pressure plate 5, preventing the protective pressure plate 5 from easily loosening in the bent busbar trough 1. The multiple return springs 7 are made of 65Mn spring steel (carbon manganese steel), with a composition of 0.62%-0.70% carbon and 0.90%-1.20% manganese. They have excellent anti-loosening and limiting advantages, high elastic limit, and can withstand large alternating loads. They are suitable for limiting scenarios that require long-term maintenance of pre-tightening force. After quenching and medium-temperature tempering treatment, the surface hardness reaches HRC42-48, with excellent wear resistance, effectively preventing the limiting contact surface from loosening due to friction. Two welding plates 2 are welded to the inner bending point of the bent busbar trough 1. The two welding plates 2 can be fixed by bolts to realize the installation of the bent busbar trough 1.

[0022] As a second embodiment of this utility model: each wire is passed through each arc-shaped groove and movably attached to the arc-shaped rubber sheet 3. Then, the protective pressure plate 5 is attached to the inside of the bent busbar groove 1 and abuts against multiple aluminum alloy separators 4, so that multiple arc-shaped rubber strips 8 are movably attached to the front end of each wire. At the same time, multiple positioning posts 6 are respectively inserted into multiple cylindrical positioning grooves. Then, a ceramic cover plate 11 is fastened to the front end of the inside of the bent busbar groove 1. Then, multiple hand-tightening screws 12 are turned so that the threaded ends of the multiple hand-tightening screws 12 pass through the bent busbar groove 1 and the ceramic cover plate 11. On the side surface of the cover plate 11, the ceramic cover plate 11 is installed and fixed. At this time, multiple spring push plates 16 will also press against multiple return springs 7 respectively, forcing multiple return springs 7 to apply pushing force to the protective pressure plate 5, thereby ensuring that each wire is in close contact with multiple arc-shaped rubber pieces 3 and multiple arc-shaped rubber strips 8. Subsequently, by turning each threaded locking block 15, each threaded locking block 15 can rotate and move within multiple embedded nuts 14, thereby adjusting the spring push plates 16 to move forward or backward, thereby adjusting the degree of pushing force of multiple return springs 7 on the protective pressure plate 5.
