Description

Technical Field

[0001] This utility model belongs to the field of fuse technology, specifically relating to a high-voltage conductive connection component for fuses. Background Technology

[0002] A fuse is an electrical device used to protect electrical equipment such as transformers from overload and short circuits. It is usually made of a metal wire or other material. When the current exceeds the set rated value, the fuse melts and breaks the circuit, thus preventing damage to the equipment in the circuit or the risk of fire.

[0003] In existing technologies, screws are used to penetrate the molten material and connect to it. However, the contact area of ​​the screw connection is small, which can lead to phenomena such as electrical discharge, electro-erosion, and oil seepage. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by providing a high-voltage conductive connection component for a fuse. A conductive ring and a nut are provided on the fuse element. The conductive ring and the nut are connected by interference fit or threaded connection, which increases the contact area and makes the contact more reliable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage conductive connection component for a fuse, comprising a fusible element and a nut, wherein a conductive ring is provided in the fusible element, and a threaded hole is provided at the top of the upper end of the conductive ring, and the nut passes through the threaded hole and is connected to the conductive ring, wherein the conductive ring and the nut are fitted by interference fit or threaded connection.

[0006] Furthermore, the conductive ring is made of aluminum.

[0007] Furthermore, the threaded hole on the conductive ring is a blind hole.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention features a conductive ring inside the melt, with a threaded hole at the upper end. The threaded hole is not a through hole but a blind hole. The nut passes through the threaded hole and engages with the conductive ring via interference fit or threaded connection, increasing the contact area, reducing oil leakage, making the structural connection more reliable, reducing partial discharge during use, and extending service life.

[0013] To enable those skilled in the art to better understand and implement the technical solution of this utility model, the present utility model will be further described below with reference to specific embodiments. However, the embodiments described are only for illustration and are not intended to limit the present utility model.

[0014] like Figure 1 The high-voltage conductive connection component of the fuse includes a nut 2, a fusible element 1, and a conductive ring 3. The conductive ring 3 is disposed inside the fusible element 1. The conductive ring 3 has a threaded hole, which does not penetrate the entire conductive ring 3. The threaded hole on the conductive ring 3 is a blind hole. The nut 2 passes through the threaded hole and is press-fitted or threadedly connected to the conductive ring 3.

[0015] The conductive ring 3 is made of aluminum.
