The applicable performance aspect of particular surroundings proposes requirement new, higher, therefore, either evidence obtaining mechanism or user are to explosion-proof
The high pressure resistant force value of entirety of motor has new requirement.What fire-proof motor was usually used at present is areola terminal box, due to it
Inner space is limited, and fluid sealant only has with the cylindrical structural that installing plate faying face is the double garden ring faces of band, the incoming line of installing plate
One threading hole, for using 6 and more than 6 motors of winding leads, its winding leads draws from same threading hole
Enter, when installing plate glue is honored as a queen in terminal box, can there is adhesion phenomenon between the lead of part, thus directly influence fire-proof motor
Overall high voltage performance.Show through hydrostatic test, when motor internal hydraulic pressure reaches 3MPa, the motor at wiring box mounting board draws
There is gap and has infiltration in line, and installing plate will have infiltration phenomenon with fluid sealant faying face part.Therefore, according to evidence obtaining mechanism pair
The new requirement of the high pressure resistant force value of fire-proof motor, and be the motor of 6Mpa to particular surroundings requirement high pressure resistant, in the prior art
Areola terminal box cannot use, areola junction box structure need to be improved, with meet domestic and international particular surroundings prevent
The use of quick-fried motor.
The content of the invention
The purpose of this utility model is to provide a kind of simple structure, safe and reliable, can effectively prevent machine winding
Lead adhesion, and disclosure satisfy that the explosion-proof high pressure resistant power areola terminal box that high pressure resistant value is more than 6Mpa.
To realize that the purpose of this utility model is adopted the technical scheme that：The terminal box include cassette holder, lid, motor around
Group lead, lead bushing, eyelet strip, wherein, lead bushing is tubular construction, and its outer circumference surface is provided with spaced-apart bosses, interval
The upper and lower part of boss is provided with the external screw thread being threadedly coupled with cassette holder and motor body respectively, in lead bushing, its top
Screw thread alveolus is provided with, middle part is provided with right angle depressurization grooves, and bottom is provided with eyelet strip location hole, and threading board is provided with location hole
Groove, eyelet strip is located in eyelet strip location hole, and is connected with its clamp, and several threading holes are laid with eyelet strip, electricity
Machine winding leads are stretched out outside lead bushing and are introduced in box body by threading hole, and the space position embedding in lead bushing has close
Sealing.
Threaded connection between the lead bushing and cassette holder and motor body is threaded flame-proof type face.
The eyelet strip is I-shaped structure, which is provided with the ear platform being connected with eyelet strip draw-in groove clamp.
The areola terminal box of the explosion-proof high water pressure resistant being made according to such scheme, the ridge set by lead bushing
Groove pressure transmission face, can be effectively increased pressure-resistant transmission length, and the right angle depressurization grooves of setting can reduce the impulsive force of internal pressure, thus increase
The strong high pressure resistant value of terminal box, the outlet structure that every, machine winding lead is independently separated by can be prevented effectively from viscous between line and line
Even, so as to greatly enhance the ability of terminal box internal pressure-resistant, it is fully able to meet the internal pressure-resistant requirement of 6Mpa, external authority recognizes
The experiment of card mechanism can reach the pressure-resistant effect of 7Mpa.
