Description
Technical field
The invention belongs to fire-proof motor technical fields, are related to a kind of explosion-proof lead connecting sleeve.
Background technique
Fire-proof motor has having been widely used in production, and the lead access of fire-proof motor needs to meet leakproofness and flame proof
The lead access of performance requirement, existing fire-proof motor is not able to satisfy above-mentioned requirements.
Summary of the invention
The present invention is in view of the above-mentioned problems, provide a kind of explosion-proof lead connecting sleeve, the connecting sleeve structure novel, leakproofness
By force, meet flame proof requirement.
A kind of technical solution according to the invention: explosion-proof lead connecting sleeve, it is characterised in that: including integrally connected every
Flame proof thread is arranged in plate bursting, flame proof nut, the flame proof nut inner ring, and flame proof plate corresponds on the body of flame proof nut inner hole end face
At least two feedthrough holes are set, and thermometric lead is arranged through the feedthrough hole, passes through resin glue between thermometric lead and feedthrough hole
Sealing.
As a further improvement of the present invention, it is connected between the flame proof plate and flame proof nut by connecting cylinder.
As a further improvement of the present invention, the outer diameter of the connecting cylinder is less than the outer diameter of flame proof nut.
As a further improvement of the present invention, the flame proof plate is equipped with chamfering far from flame proof nut one end.
The technical effects of the invention are that: product of the present invention structure is simple, ingenious reasonable, in use, leakproofness
Energy and explosion insulation performance are all satisfied requirement, while structure novel, and convenient for operation, application range is wider.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
A specific embodiment of the invention is further described with reference to the accompanying drawing.
Fig. 1, in 2, including feedthrough hole 1, thermometric lead 2, flame proof nut 3, flame proof plate 4, connecting cylinder 5 etc..
As shown in Figure 1, 2, the present invention is a kind of explosion-proof lead connecting sleeve, flame proof plate 4, flame proof spiral shell including integrally connected
Mother 3,3 inner ring of flame proof nut are arranged flame proof thread, flame proof plate 4 correspond in flame proof nut 3 be arranged on the body of hole end surface to
Few two feedthrough holes 1, thermometric lead 2 are arranged through the feedthrough hole 1, close by resin glue between thermometric lead 2 and feedthrough hole 1
Envelope.Feedthrough hole 1 can be set to multi-turn cyclic structure on flame proof plate 4, to meet corresponding duty requirements.
It is connected between flame proof plate 4 and flame proof nut 3 by connecting cylinder 5.
The outer diameter of connecting cylinder 5 is less than the outer diameter of flame proof nut 3.
Flame proof plate 4 is equipped with chamfering far from 3 one end of flame proof nut, and the shape of flame proof plate 4 is set as regular hexagon structure.
In specifically used, the size of 3 outer diameter of flame proof nut is generally 16 ~ 60mm, the axis of flame proof nut 3 and connecting cylinder 5
It is 16 ~ 60mm to length.Situation is configured the quantity and specification for the feedthrough hole 1 being arranged on flame proof plate 4 according to actual needs, is surveyed
Thermometric lead 2 and feedthrough hole 1 are sealed setting after being pierced by corresponding feedthrough hole 1, through resin glue by warm lead 2, then
Explosion-proof lead connecting sleeve is connect by flame proof nut 3 with terminal block housings, the requirement of flame proof sealing is reached.
Product of the present invention sealing structure is strong, and compound flame proof requirement, structure novel is widely used convenient for operation.
