Problems solved by technology

However, when this type of electrical connector is used, the assembly requirements for the end cap are extremely strict, otherwise it is easy to make the flameproof electrical connector lose the flameproof function, and because the end cap and the socket are two components, once the end cap is lost, the socket will be lost. Explosion-proof function, can not be used

Embodiment Construction

[0013] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] Specific embodiments of the flameproof electrical connector of the present invention, such as Figure 1 to Figure 3 As shown, the flameproof electrical connectors are respectively a plug connector and a socket connector. The plug connector includes a plug housing 12, and a plug insulator 111 is arranged in the inner cavity of the plug housing 12, and the plug insulator 111 is fixed on the plug housing by a collar. In the inner cavity of the body 12, a plug contact 14 is installed in the plug contact mounting hole on the plug insulator 111, and the plug contact mounting hole is provided with an explosion-proof surface of the contact mounting hole extending along its axial direction, and the plug contact 14 is a cylindrical contact piece. The outer peripheral surface of the plug contact piece 14 is provided with an explosion-proof surface extending ...

Abstract

The invention relates to the electric connection field, and particularly to an explosion-suppression electric connector. The explosion-suppression electric connector comprises an electric connector shell, wherein an insulator is arranged in an inner cavity of the electric connector shell; the electric connector shell is a barrel-shaped shell; the insulator is a columnar insulator which is matched with the barrel-shaped shell; a shell explosion-suppression surface which extends in an axial direction of the barrel-shaped shell is arranged on the inner circumferential surface of the barrel-shaped shell; an insulator explosion-suppression surface which extends in an axial direction of the columnar insulator is arranged on the outer circumferential surface of the columnar insulator; and the shell explosion-suppression surface and the insulator explosion-suppression surface are in clearance fit to form an insulator explosion-suppression gap which extends in the axial direction of the insulator with a first set length. The insulator explosion-suppression surface and the shell explosion-suppression surface are in clearance fit to form the insulator explosion-suppression gap; the insulator explosion-suppression gap can weaken energy generated in explosion to avoid detonation of external environment by the explosive so as to realize the explosion-suppression effect; and therefore, the explosion-suppression function can be realized without employing an end cover.

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] Electrical connectors with flameproof function also appear in the prior art. The plug-in end of the existing flameproof electrical connector is equipped with an end cover to isolate the interior of the connector from the external environment and achieve a flameproof effect. However, when this type of electrical connector is used, the assembly requirements for the end cap are extremely strict, otherwise it is easy to make the flameproof electri...
