Connecting structure capable of reducing heating of wiring terminal

Abstract

The invention relates to a connecting structure capable of reducing heating of a wiring terminal. The connecting structure comprises a bolt body and a gasket, wherein the bolt body comprises a screw rod part and a head part, the head part is provided with a screw cap, the screw cap is detachably mounted on the head part, the screw cap is provided with an extension part, the gasket is provided with a contact part, and an indication assembly is arranged between the extension part and the contact part. According to the invention, the contact area of a head part and a conductor is increased through an extension part arranged on a nut, the conductor resistance is reduced by increasing the sectional area of the conductor under the condition that the conductor resistivity and the conductor length are not changed, and when the current passing through the conductor is fixed, the heat productivity of the conductor is reduced, so that the possibility that the bolt is damaged due to overheating caused by long-term electrification of the contact surface is reduced; and the gasket is arranged on the fixed section, so that the sectional area of the conductor at the joint of the bolt and the conductor is increased, the heating of the bolt is reduced, the normal use of the high-voltage drop-out fuse is ensured, and the safety performance is improved.

Description

technical field [0001] The invention relates to a connection structure capable of reducing heat generation of connecting terminals. Background technique [0002] The connection between existing terminals and high-voltage drop-out fuses, switches and other electrical appliances is connected by bolts. Because the screw heads and gaskets of existing bolts are small, and even the gaskets are not as big as the screw head, the screw head is actually in contact with the screw head. The area is not large. Due to the small contact area, the wiring terminal heats up more seriously after long-term power-on, so that the connection surface between the wiring terminal and the electrical equipment increases due to the increase of loop resistance, or poor contact causes heating, damage and failure. Contents of the invention [0003] The purpose of the present invention is to provide a connection structure that can reduce heat generation of the connection terminal, increase the contact are...
