Abstract
The utility model discloses a kind of convenient type flame-proof type heating terminal box, overcome in prior art, the heating of explosion-proof motor stator connects the problem of drawing electric source connecting box unreasonable structure.This utility model contains housing, mount pad and lid, the top of housing connects lid, bottom is socketed on mount pad, the line outlet of housing side is equipped with explosion-proof Glan joint, the integral insulation plate of hollow is provided with in housing, be socketed with connection bolt in integral insulation plate, the upper end of connection bolt is connected with nut.This technology substantially increases the speed of motor heating device assembling, structure is optimized more, decreases the probability of damage of components in terminal box, and can save the motor useful space, easy installation and reliable explosion-proof motor heating wire box, and the degree of protection of IP66 can be reached.
Description
Technical field
This utility model relates to a kind of motor appurtenances, particularly relates to a kind of convenient type flame-proof type heating terminal box.
Background technology
In known technology, the terminal box of drawing power supply is connect for the heating of explosion-proof motor stator, generally by adopting connection bolt and terminal sleeve to arrange flameproof joint, draw or adopt sealant pouring and sealing to reach the requirement of flame proof by firmly connecting, but the building of fluid sealant on the fixing and potting structure of terminal sleeve on junction box seat in above two kinds of structures, because operating space is little, manufacturability is poor.
Utility model content
The utility model overcomes in prior art, and the heating of explosion-proof motor stator connects the problem of drawing electric source connecting box unreasonable structure, the convenient type flame-proof type heating terminal box providing a kind of structure simple, easy to use.
Technical solution of the present utility model is, there is provided a kind of convenient type flame-proof type heating terminal box with following structure: containing housing, mount pad and lid, the top of housing connects lid, bottom is socketed on mount pad, the line outlet of housing side is equipped with explosion-proof Glan joint, be provided with the integral insulation plate of hollow in housing, be socketed with connection bolt in integral insulation plate, the upper end of connection bolt is connected with nut.
Described mount pad gos deep into motor case, is tightly connected with motor case, and by Bolt to position in motor case.Housing adopts cylindrical shape or eight-sided formation.Lid is connected with housing seal.
The minimum electric clearance L >=10mm of described nut and housing, the creepage distance S >=6mm of integral insulation plate vertical direction, the top of connection bolt and the minimum electric clearance H >=10mm of lid.
Compared with prior art, the utility model convenient type flame-proof type heating terminal box has the following advantages: what adopted in the past is the structure of independent terminal block, and complex structure, workshop installation step is loaded down with trivial details.Lead-in wire in winding adopts rubber seal technique after introducing terminal box, and man-hour is longer, and cost is high.
The utility model is independent heating or the convenient terminal box of thermometric, does not need to adopt rubber seal technique, and heating or thermometric lead-in wire are directly crimped on connection bolt, passes, use bolt to fix at junction box from insulation integral insulation plate.With strong points, cost is low.In the past due to the restriction of terminal box overall dimension, low center height motor can not meet independent thermometric or heating requirements, after designing this terminal box, well solves this problem, realize the simple and efficient extraction of heat lead in motor winding, substitute terminal sleeve structure completely.
Substantially increase the speed of motor heating device assembling, structure is optimized more, decreases the probability of damage of components in terminal box, and can save the motor useful space, easy installation and reliable explosion-proof motor heating wire box, and the degree of protection of IP66 can be reached.
