Embodiment 1

[0064] Such as Figure 1~Figure 15 As shown, the grounding protection flameproof plug includes a middle-pass shell assembly, the shell assembly is provided with a base assembly, and the shell assembly includes an upper shell 3 and a lower shell 4 that can be combined with each other; and the embedded One end of the upper shell 3 and the lower shell 4 provided with the mounting seat can be socketed and combined.

[0065] Specifically, such as figure 1 , figure 2 , Figure 11 , Figure 12As shown, the upper casing 3 is a circular tube shell, the top inside of the upper part of the upper casing 3 is provided with an inner slope surface 301, and the upper surface of the casing is provided with a long convex key 302, and the long convex key 302 is connected with the upper casing. An annular groove 1 304 is arranged between the annular bosses 1 303 of the body 3 for placing the sealing outer ring 20, and an inner boss 305 and an annular groove 2 306 are respectively arranged in...

Embodiment 2

[0077] A method for preparing and assembling a grounding protective flameproof plug, comprising the following steps:

[0078] Step one, the assembly of the base assembly.

[0079] The grounding pin assembly 2 is formed by welding the grounding pin 201 and the grounding reed 202; several butt joint pins 1 and the grounding pin assembly 2 are respectively equipped with crimping terminals 8 to form a crimping joint. The joint part is fixedly combined with the mounting seat to form a base joint part.

[0080] Further, specifically, the mounting ring grooves on both sides of the ring groove 4 of the docking pin 1 and the grounding pin assembly 2 cooperate with the upper end surface and the lower end surface of the rubber base 7 respectively to clamp and limit, and the upper base 5. Load it from the top of the docking pin 1 and the grounding pin assembly 2. The lower end surface of the upper base 5 is matched with the upper end surface of the rubber base 7. The lower base 6 is conn...

Abstract

The invention relates to a grounding protection explosion-proof plug which comprises a hollow shell assembly. A base assembly is arranged in the shell assembly, and a plurality of crimping assemblies are arranged in the base assembly; the base assembly further comprises a mounting seat embedded in the shell assembly, the plurality of crimping assemblies are fixed on the mounting seat in a penetrating manner, and each crimping assembly comprises a plurality of butting contact pins and a grounding contact pin assembly; the grounding contact pin assembly comprises a grounding contact pin and a grounding reed arranged on the grounding contact pin, and the grounding reed is in contact with and abuts against the shell assembly. According to the grounding protection explosion-proof plug provided by the invention, the grounding protection form of a connector is expanded, and the technical problems that in the prior art, an electric connector assembly is not easy to ground in a small space and is unstable in grounding are solved.

Description

technical field [0001] The invention relates to the technical field of electric connectors, in particular to an explosion-proof plug with grounding protection that can work in the environment of combustible gas and dust. Background technique [0002] With the continuous development of electrical connectors, their functions have been continuously improved. The functions of petroleum and chemical electrical connectors are particularly complex. Not only the connectors and components are required to meet the requirements of airtightness and watertightness, but also the connectors themselves are required to be foolproof. Explosion-proof, electromagnetic shielding, and grounding protection capabilities are all problems that need to be solved in the prior art. [0003] The connector itself will generate a certain amount of static electricity during long-term use. At the same time, when the connector fails, the housing may be charged. In order to prevent the connector housing from b...
