Problems solved by technology

[0003] When two metal wires are connected with electricity, at the moment when the two metal wires touch, due to the existence of a large contact resistance, sparks and heat will be generated at the contact point. With the stable contact of the metal contacts, the sparks and heat will follow. Disappearance, when two charged metal wires are separated, often due to the existence of the load, sparks will also be generated at the moment of separation of the contacts, so the sparks and heat of the electrically connected contacts in flammable and explosive places can easily cause explosion accidents

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] figure 1 It is the socket part of the explosion-proof electrical connection device. 101 is the shell of the socket component, which contains: socket contacts 104 and reed switches 108 . The dry reed switch 108 is composed of an input lead 102 , an output lead 106 , a contact 103 and a contact 107 . 105 is a connecting wire, which is used to connect the output lead wire 106 of the dry reed switch and the socket contact piece 104, and 109 is an input terminal connected to the lead wire 102 of the dry reed switch input end. If the input terminal 109 is connected to a power source, the reed switch 108 is in an open state, and the contact 103 and the contact 107 are in a separated state, so the socket contact piece 104 is in a non-electric state.

[0017] figure 2 It is a plug part of an explosion-proof electrical connection device. 201 is the s...

Abstract

The invention relates to an anti-explosion electric connection device which is applied to electrified connection at flammable and explosive places. The anti-explosion electric connection device is characterized by comprising a socket component and a plug component. The socket component at least comprises a reed pipe and a socket contact plate which is connected with one end of the reed pipe. The plug component at least comprises a permanent magnet and a plug contact plate. When the socket component is separated from the plug component, the reed pipe is in an open-circuit state, and when the plug component is inserted into the socket component, the reed pipe is in a closed powered-up state. The anti-explosion electric connection device has the advantages that when the plug component is inserted into or separated from the socket component, the electric connection contact plate is in a powered-down state at the connection moment or the separation moment, and therefore electric sparks are prevented from being generated, and the intrinsic safety anti-explosion effect is achieved.

Description

technical field [0001] The invention relates to an explosion-proof electrical connection device, which is applied to live connection in inflammable and explosive places. [0002] Background technique [0003] When two metal wires are connected with electricity, at the moment when the two metal wires touch, due to the existence of a large contact resistance, sparks and heat will be generated at the contact point. With the stable contact of the metal contacts, the sparks and heat will follow. Disappearance, when two live metal wires are separated, often due to the existence of the load, sparks will also be generated at the moment of separation of the contacts, so the sparks and heat of the electrically connected contacts in flammable and explosive places can easily cause explosion accidents. At present, explosion-proof methods are divided into isolation explosion-proof and intrinsically safe explosion-proof. Isolation-proof explosion-proof is to use a metal container to seal ...
