Embodiment Construction

[0030] In order to facilitate the understanding of the present application, a more comprehensive description of the connection bolts, the cable connection head and the high-voltage switchgear will be made below with reference to the related drawings. Preferred embodiments of connecting bolts, cable connectors and high-voltage switchgear are given in the drawings. However, the connecting bolts, cable connectors and high voltage switchgear may be implemented in many different forms and are not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of connection bolts, cable connectors, and high voltage switchgear will be more thorough and complete.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connec...

Abstract

The invention relates to a connecting bolt, a cable connector and a high-voltage switch cabinet. A first connecting thread and a second connecting thread are formed on the outer wall of the connectingbolt, the connecting bolt comprises a copper split body and a steel split body, a first external thread and a second external thread are arranged on the peripheral wall of the copper split body, andthe cross section of the copper split body is fan-shaped; the steel split bodies are connected in an inserted mode, and third external threads and fourth external threads are arranged on the peripheral walls of the steel split bodies. The third external thread is used for being jointed with the first external thread when the steel split body and the copper split body are spliced, so that the firstexternal thread and the third external thread jointly form a first connecting thread; the connecting bolt is composed of a steel structure and a copper structure, and the structural form of a singlematerial of a traditional connecting bolt is changed, so that the strength of the connecting bolt is considered and the overflowing capacity of the connecting bolt is improved, therefore, heating of the connecting bolt is reduced, and the problem that the connecting bolt generates heat seriously in the using process is solved.

Description

technical field [0001] The present application relates to the technical field of cable connection, in particular to a connection bolt, a cable connection head and a high-voltage switch cabinet. Background technique [0002] The cable connector of the traditional closed high-voltage switch cabinet includes a straight-through conductive rod. One end of the conductive rod extends into the interior of the cabinet for conductive connection, and the other end of the conductive rod is provided with a common connection bolt. One end of the connecting bolt is connected to the end of the conductive rod, and the other end passes through the installation hole of the terminal to realize the conductive connection between the conductive rod and the terminal, so that the conductive rod is connected to the external cable through the terminal. [0003] However, the connecting bolts of the traditional cable connector are made of stainless steel, which has poor overcurrent capability, resulting...
