Description

Technical Field

[0001] The invention relates to the technical field of power electrical equipment, and in particular to a connector for transformer wiring. Background Art

[0002] In the complex and sophisticated power system, the transformer plays an irreplaceable key role. As the core electrical equipment, the stability and safety of its operation are directly related to the efficiency and reliability of the entire power system. Therefore, the safety and reliability of transformer wiring are particularly important. Any minor flaw may have an immeasurable impact on the overall performance of the system.

[0003] For a long time, traditional transformer wiring methods have relied on relatively simple wire clamps or connectors to fix and connect wires. However, these seemingly convenient traditional methods have exposed many safety hazards in actual applications. Specifically, the wire clamp connection method often becomes loose due to the dual effects of current and external environment for a long time. Once the wire clamp is loose, it may cause poor contact, resulting in unstable current transmission, and even extreme situations where the wires fall off. These undesirable phenomena will not only seriously affect the stability of the circuit and the normal operation of the power system, but may also pose a serious threat to the personal safety of operators.

[0004] In addition, grounding treatment is a crucial link in the transformer wiring process, and its importance cannot be ignored. Good grounding treatment can effectively ensure the safety of the power system and prevent equipment damage or casualties caused by accidents such as lightning strikes and leakage. Unfortunately, however, many existing connector clamps are often not fully considered in the design of the convenience and reliability of grounding operations. This makes the grounding work complicated and cumbersome in actual operation, which not only increases the difficulty of operation, but also may cause a series of safety problems due to poor grounding. It can be seen that the existing technology still needs to be improved and improved. Summary of the invention

[0013] In one embodiment of the present invention, the insulating layer is vulcanized silicone rubber.

[0014] The beneficial effect of the above embodiment is that the vulcanized silicone rubber, as the insulating layer material, has good high temperature resistance, aging resistance and electrical insulation performance, and can effectively protect the internal circuit from the influence of the external environment.

[0015] In one embodiment of the present invention, the first cover body and the second cover body are both made of vulcanized silicone rubber.

[0016] The beneficial effect of the above embodiment is that the first cover body and the second cover body are made of vulcanized silicone rubber material, which not only provides good sealing performance to prevent moisture and dust from entering, but also increases the flexibility and impact resistance of the cover body.

[0017] In one embodiment of the present invention, the angle between the switch branch line and the lightning protection branch line is less than 90°.

[0018] The beneficial effect of the above embodiment is that the angle between the switch branch line and the lightning protection branch line less than 90° helps to reduce interference and stress concentration between lines, and helps to reduce the overall volume.

[0019] In one embodiment of the present invention, a guard edge is further included. The guard edge is disposed at the opening edges of the first cover body and the second cover body, and the edge of the guard edge is received inwardly.

[0020] The beneficial effect of the above embodiment is that the guard edge provides additional protection for the first cover body and the second cover body, preventing damage caused by collision during installation or use, and protecting the integrity of the wiring terminal.
