Description
Technical field
The utility model relates to explosion separation motor splicing application, particularly a kind of explosion separation motor heater wiring assembly.
Background technology
As the heater termination of motor, require that cable protective is high, easy-to-connect, especially explosion-proof motor requires higher to heater wiring.Heater lead need be introduced for terminal block in heater connection box from motor internal, owing to relating to motor internal wiring, except meeting the actual conditions also will considering produced on-site except requirement of explosion proof.Traditional explosion-proof motor heater introduces heater connection box by connection bolt, and this infrastructure cost is higher, complex structure.
Therefore, need to improve existing explosion separation motor heater termination, make that its structure is simple, safe and reliable, convenient operation, and can reduce costs.
Utility model content
In view of this, the utility model provides a kind of explosion separation motor heater wiring assembly, and its structure is simple, safe and reliable, convenient operation, and can reduce costs.
Explosion separation motor heater wiring assembly of the present utility model, comprise terminal box and be arranged on the line bank in terminal box, also comprise and being arranged at for going between by and the rubber seal assembly sealed it in terminal box, described rubber seal assembly comprises fluid sealant bucket and is wrapped in lead-in wire outward and the fluid sealant of encapsulating curing molding in fluid sealant bucket.
Further, fluid sealant bucket inwall is helicitic texture.
Further, fluid sealant bucket is T-shaped nested structure, and its cover plate is provided with through wires hole.
Further, fluid sealant by epoxy resin and low molecule pa resin by weight formulated.
Further, cylinder explosion-insulation surface is formed between fluid sealant bucket and described terminal box.
Further, line bank comprises guide rail and is arranged on terminal on guide rail, and described terminal comprises both sides end plate and the binding post be arranged between the end plate of both sides and earth terminal.
The beneficial effects of the utility model: explosion separation motor heater wiring assembly of the present utility model, structure is simple, convenient operation, by being filled with the fixture of fluid sealant bucket as heater lead of fluid sealant, make the mode of connection better tightness of heater lead, wiring is flexible, cost-saving, and makes overall structure meet the requirement in the explosion-proof place of multiple difference (Exd I Mb, Exd II AT4Gb, Exd II BT4Gb, Exd II CT4Gb).
