Abstract

The invention relates to a waterproof anti-explosion cable connector, which comprises a plug, a socket, a plug protective cover, a socket protective cover, an outer cover, a rubber sealing ring, a compaction nut, a stop thread, a plug cover, a socket cover, a waterproof O-ring, a rubber spacer, a fixing flange disc and a connection chain. The outer cover is used for fastening the plug protective cover and the socket protective cover; the rubber sealing ring is used for sealing an outgoing line of a cable; the compaction nut is used for compacting the rubber sealing ring; the stop thread is used for plugging off the plug and the socket; and the connection chain is used for being connecting with the plug protective cover. Through the technical scheme of the waterproof anti-explosion cable connector disclosed by the invention, the part of outgoing line of the cable forms a cavity sealed to outside because of the matching of the rubber spacer, the compaction nut and the cable, and a contact surface of a plug part A and a socket part B form an explosion releasing surface, thus outside dangerous gas are not ignited when the inner cavity is exploded, and design purposes of the waterproof anti-explosion cable connector of the invention are realized.

Description

technical field [0001] The invention relates to a cable connection device, in particular to a waterproof and explosion-proof cable connection device which can be used in a place where a certain concentration of explosive gas is mixed in the air. Background technique [0002] In many places in the petroleum and petrochemical field, such as oil depots, gas stations, oil mining areas, etc., because there is a certain concentration of explosive gas in the air, these places are called dangerous areas. Electrical equipment installed in these areas must be The safety of use can only be guaranteed by meeting the GB3836-2000 "Electrical Equipment for Explosive Gas Atmospheres" standard. However, ordinary cable connection devices cannot be used in places where explosive hazardous gases exist because they do not meet the requirements of GB3836-2000 on explosion protection. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof and explosio...
