Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structure principle chart of explosion-proof electrifying box.Explosion-proof electrifying box consists of casing 10, case lid 11, rotating shaft 12, and case lid 11 can carry out open and close by 12 pairs of casings of rotating shaft 10; The interior layout supply socket 40 of casing 10 and anti-explosion magnetic controlled switch 100, be provided with permanent magnet 30 on case lid 11.The zero line of power supply, ground wire are connected to N, the E terminals of supply socket 40, and the live wire of power supply is connected to the L terminals of supply socket by anti-explosion magnetic controlled switch 100.When case lid 11 is opened, anti-explosion magnetic controlled switch 100 is in open-circuit condition, nothing electricity in supply socket 40, while inserting plug, in supply socket, not having electric spark produces, after plugging steady, plug closes case lid 11, the permanent magnet 30 arranging on case lid 11 is near anti-explosion magnetic controlled switch 100, anti-explosion magnetic controlled switch 100 closures make supply socket 40 obtain electricity, because anti-explosion magnetic controlled switch 100 is closed and disconnection all can not produce electric spark or electric spark is isolated, power taking process is like this intrinsic safe explosion-proof, while opening case lid 11, the permanent magnet 30 arranging on case lid 11 is away from anti-explosion magnetic controlled switch 100, anti-explosion magnetic controlled switch 100 open circuits make supply socket 40 without electricity, at this moment pull out plug and also can not produce electric spark in supply socket, so whole operating process is all intrinsic safe explosion-proof.The 13rd, plug wires outlet.
Described anti-explosion magnetic controlled switch is defined as: take magnetic field as control mode, switch switching produces without electric spark, or the electric spark producing is isolated in enclosure space, as noncontacting switch, dry-reed tube switch.
In order further to improve requirement of explosion proof, casing, case lid are made of metal.
