Specific implementation mode
For the structure, feature and its effect to the utility model, can have further understand and recognize, now lift one compared with
Good embodiment, and be described with reference to the accompanying drawings as follows：
According to Fig. 1 and Fig. 2：A kind of tubular metal electrical heating elements of high electrical insulation properties, including heating wire 1,
Insulation stopping 2, electrode leads to client 3, joint filling material 4, metal shell 5, exit insulating layer 6, non-hot zone 7, hot zone 8,
Boundary line 9, plastic section 10 and nozzle 11 are equipped with hair at the tubular metal electrical heating elements center of inside of the high electrical insulation properties
The tubular metal electrical heating elements inside of heated filament 1, the high electrical insulation properties is filled with Insulation stopping 2, described high electrical
The tubular metal electrical heating elements end point of insulation performance is equipped with non-hot zone 7, the tubular metal of the high electrical insulation properties
Electrical heating elements end point is internally provided with joint filling material 4, the tubular metal electrical heating elements table of the high electrical insulation properties
Portion is surrounded by metal shell 5, and 3 some of electrode leads to client stretches into non-hot zone 7, and another part exposes nozzle 11, institute
It states 3 part of electrode leads to client and is brought out the end package of insulating layer 6, a part of exposing nozzle 11 of the exit insulating layer 6 is described
6 another part of exit insulating layer stretch into non-hot zone 7, the exit insulating layer 6 stretches into high electrical insulation properties
