[0002] During the use of transformers, it is often necessary to connect multiple lines. Sometimes these lines need to be connected to each other or to other line unit devices. In order to ensure the reliability and safety of the connection, insulating tape is used to wrap the line connection wiring in routine operations, which can effectively prevent rainwater intrusion and provide insulation protection. However, after long-term use, the insulating tape is prone to aging and damage, which will cause serious safety hazards to the line connection. Therefore, measures need to be taken to effectively protect the line connection.

[0003] According to a publicly disclosed transformer line protection structure (publication number: CN217036667U), the above application includes a fastening mechanism and a limiting mechanism. The fastening mechanism includes a clip and a block.

A slide groove is opened on the inner circular wall of the clip, and the corresponding block can be inserted into the slide groove.

[0004] However, during the actual use of the above-mentioned equipment, the wires generate heat, and the heat will accumulate in the connectors and cannot be dissipated in time, causing damage or aging of the wire insulation material, thereby reducing the insulation performance and increasing safety risks such as motors and electric shock. In view of this, we propose a line protection structure that facilitates heat dissipation. Utility Model Content
