Abstract
The utility model discloses an auxiliary wiring box of a flameproof-type motor, which has the advantages of simple structure, good flameproof effect, safety and reliability and comprises a wiring-box shell and a cable guiding device, wherein the cable guiding device is arranged on the wiring-box shell, and the cable guiding device comprises a cable guiding channel arranged on the wiring-box shell and a sealing part arranged on the guiding channel; the cable guiding channel comprises a guiding pipe and a pore plate, wherein the guiding pipe is connected onto the wiring-box shell, the pore plate is connected to the guiding pipe and adapted to the wire diameter of a cable, and the sealing part is arranged in the guiding pipe; a wiring terminal arranged in the wiring-box shell is a spring wiring terminal; the cable guided into the wiring-box shell is an intrinsic-safety type flame-retardant multi-core cable; and the sealing part is an explosion-proof sealing ring. The intrinsic-safety type flame-retardant multi-core cable is hermetically connected to the auxiliary wiring box by the explosion-proof sealing ring through a compression nut and the pore plate.
Description
Background technology
The utility model relates to a kind of auxiliary connection box of explosion-proof motor.
Technical background
General jumbo explosion-proof motor all must be installed temperature element and moistureproof heating tape, temperature element and moistureproof heating tape lead-in wire are all introduced in the flame-proof type auxiliary connection box, tradition flame-proof type auxiliary connection box generally adopts binding post to introduce, and does not use but this connection terminal structure is suitable for the resistance temperature measurement in multiply number, little line footpath; Also useful fluid sealant carries out the flame-proof type auxiliary connection box of glue envelope, but this glue seal structure causes easily that when expanding with heat and contract with cold glue envelope gap changes even cracking, causes flame proof to lose efficacy, and security incident takes place.
The utility model content
The purpose of this utility model is the auxiliary connection box that a kind of explosion-proof motor is provided at the deficiency that prior art exists.This auxiliary connection box is simple in structure, and usage range is wide, and flame proof is effective, and is safe and reliable.
The technical solution of the utility model comprises terminal block housings, is located at the cable let-off gear(stand) on the terminal block housings, and described cable let-off gear(stand) comprises the cable derivation passage of being located on the described terminal block housings, and the seal formation of being located at described derivation passage.
Described cable is derived passage and is comprised that one is connected in the delivery line on the described terminal block housings, and is connected in orifice plate described delivery line, that directly adapt with cable wire and constitutes, and described seal is located in the described delivery line.
The binding post of being located in the described terminal block housings is a spring connecting terminal; The cable of introducing in the described terminal block housings is the fire-retardant multi-core cable of intrinsic safety type; Described seal is explosive-proof sealed circle.
After the utility model auxiliary connection box is used clamp nut crush seal circle, sealing ring and cable and line hole do not have the gap, meet the flame proof requirement, and the flame proof gap can not lose efficacy, can prevent that explosive flame in the motor master chamber from can not lead to cable-through hole or cable and importing the auxiliary connection box into.
The utlity model has following advantage:
Intrinsic safety type multicore flame retardant cable can prevent that cable is on fire, ignites the damp in the cavity.
Just can introduce the auxiliary connection box to multi-thread temperature element and moistureproof heating tape lead-in wire with one or two intrinsic safety type multicore flame retardant cables (general light current, forceful electric power are separately selected for use), number of cables is few, the line footpath is little, identify clear, marshalling.
Cable and spring connecting terminal join, and be easy for installation and have locking functions, guarantees that wiring is reliable and stable, produces electric arc, spark when avoiding switching on.
Description of drawings
Figure is the utility model structural representation.
Embodiment
As shown in the figure, on the base plate 6 of terminal block housings 7, offer a through hole 5, be connected with the delivery line 8 of a length corresponding to this through hole 5 on the base plate 6 greater than explosive-proof sealed circle 2 thickness, the free end of delivery line 8 is sealedly connected with an aperture approximately greater than the orifice plate 9 of the fire-retardant multi-core cable 1 of intrinsic safety type, and explosive-proof sealed circle 2 places the inner chamber of delivery line 8.One end of the fire-retardant multi-core cable 1 of intrinsic safety type (core of cable is several to be selected for use according to temperature element and heating tape number of leads) and the corresponding temperature element of motor cavity 10 and moistureproof heating tape lead-in wire join, and the other end joins through the through hole 5 of orifice plate 9, delivery line 8, explosive-proof sealed circle 2 and base plate 6 and the spring connecting terminal 4 in the terminal block housings 7; Explosive-proof sealed circle 2 is sealedly and fixedly connected the fire-retardant multi-core cable 1 of intrinsic safety type in the auxiliary connection box by clamp nut 3 and orifice plate 9.
Claims (3)
1. the auxiliary connection box of an explosion-proof motor, comprise terminal block housings, be located at the cable let-off gear(stand) on the terminal block housings, it is characterized in that described cable let-off gear(stand) comprises the cable derivation passage of being located on the described terminal block housings, and the seal formation of being located at described derivation passage.
2. according to the auxiliary connection box of the described explosion-proof motor of claim 1, it is characterized in that described cable derivation passage comprises that one is connected in the delivery line on the described terminal block housings, and be connected in orifice plate described delivery line, that directly adapt with cable wire and constitute, described seal is located in the described delivery line.
