Background technology
In recent years along with the fast development of China's oil chemical industry, the environment for use of flameproof motor is more severe.Flameproof motor develops into today, and motor connecting cartridge structure becomes one of key link, and particularly in the environment having hydrogen and acetylene, safe and reliable is very important.Require the explosive gas mixture explosion time of motor interior, flameproof enclosure should not damage or have an impact the change of explosion insulation performance; Internal explosion flame does not allow the blast being caused extraneous explosion admixture of gas by the flameproof joint of shell.Use traditional Construction of Flame-proof Terminal not reach the requirement of ExdIICT1 ~ T4 due to flame proof gap and flame proof effective length, the blast of the explosive gas mixture of external environment condition can be caused.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, a kind of flameproof motor junction box structure is provided, ensure that flame-proof type motor is reliable in the environment having hydrogen and acetylene etc. easily to set off an explosion, meet the environment for use that hydrogen and acetylene etc. easily set off an explosion.
According to the technical scheme that the utility model provides, a kind of flameproof motor junction box structure, comprises junction box seat and is arranged on the connector cover on junction box seat, junction box seat arranges terminal sleeve, in terminal sleeve, arrange connection bolt, connection bolt stretches into junction box seat inside; Described junction box seat arranges terminal box bucket, terminal box bucket arranges pressing plate; Feature is: on the face that described junction box seat is connected with the support wire outlet seat of motor, form the first seam face; Described connector cover is connected by the second seam face with between junction box seat; Form cylindric explosion suppresion surface between described connection bolt and terminal sleeve, be connected by flame proof thread between terminal sleeve with junction box seat, and packing ring and stop washer are set between terminal sleeve and junction box seat.
Further, described junction box seat is connected by bolt with the support wire outlet seat of motor.
Further, O-ring seals is set between described connector cover and junction box seat.
Further, connect by bolt between described connector cover and junction box seat.
Further, bolt presses sealing ring and metal washer is passed through between described terminal box bucket and junction box seat.
Further, described sealing ring is concentric with terminal box bucket.
Described in the utility model kind of flameproof motor junction box structure, structure is simple, is convenient to install, and flame proof requires the requirement meeting flame proof mark ExdIICT1 ~ T4 completely, makes motor running safe and reliable.
