Abstract

The invention relates to the field of electrical connection, in particular to an explosion-preventing electrical connector. The explosion-preventing electrical connector comprises an electrical connector shell, wherein an insulation body is arranged in an inner cavity of the electrical connector shell, a contact element installation hole is formed in the insulation body and is used for installing a contact element, the contact element is arranged in the contact element installation hole, a contact element explosion-preventing surface is arranged on a peripheral surface of the contact element and extends along an axial direction of the contact element, a contact element installation hole explosion-preventing surface is arranged on the hole wall of the contact element installation hole and extends along the axial direction of the contact element installation hole, the contact element explosion-preventing surface and the contact element installation hole explosion-preventing surface are in clearance fit to form a contact element explosion-preventing gap extending along the axial direction of the contact element by a first preset length. The contact element explosion-preventing gap can be used for reducing energy generated by explosion, and an explosion prevention effect is achieved; the contact element and the contact element installation hole in the insulation body are in clearance fit during installation, and the contact element is disassembled to be maintained or replaced once damaged; and the explosion-preventing electrical connector can be used in a press wire type cable product, and the application range of the explosion-preventing electrical connector is expanded.

Description

technical field [0001] The invention relates to the field of electrical connection, in particular to a flameproof electrical connector. Background technique [0002] In various electrical equipment, the amount of electrical connectors is increasing. During use, electrical connectors are required to have different functions to adapt to different use occasions. For example, in explosive gas environments, they need to be installed in explosion-proof boxes An electrical connector with flameproof function is installed on the body. [0003] There are also electrical connectors with flameproof function in the prior art. The existing flameproof electrical connectors mainly include plugs and sockets. By assembling end caps on the sockets, the internal and external environments of the connectors are isolated to achieve flameproof effects. . However, when this type of electrical connector is used, the assembly requirements for the end cap are extremely strict, otherwise it is easy to...
