121 all in the insulation tube 130.
In other embodiments, the insulation tube 130 can also be Split type structure, be sheathed on two resistor cores 120 respectively
On.
Further, the connecting lead wire 121 between two resistor cores 120 is provided with detachable terminal assemblies, can facilitate
Two resistor cores 120 are connected and separated
Further, the terminal assemblies are connected by soldering.
In one of the embodiments, organic siliconresin (not shown) is applied on the resistor core 120.Effectively prevent electricity
Hinder between the resistance silk on core 120 in the case where expanding with heat and contract with cold mutually and together, reduce resistance and short-circuit possibility occurs.
In one of the embodiments, porcelain pad (figure is not marked) is provided between the insulation sleeve 130 and the aluminum hull 110, is prevented
Only directly contacted between resistor core 130 and aluminum hull.
Further, the porcelain pad includes the rear pad 141 positioned at the corresponding position of connecting lead wire 121, corresponding in insulation tube 130
The middle pad 142 in portion and the flake 143 positioned at the opening of insulation tube 130.
Further, the porcelain pad is provided with locating slot (figure is not marked) so that the insulation tube 130 is limited in the positioning
In groove.
In one of the embodiments, the part that the lead-out wire 122 is located in the aluminum hull is arranged with insulating sleeve
1221。
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, make some equivalent substitutes or obvious modification without departing from the concept of the premise utility, and performance or
Purposes is identical, should all be considered as belonging to the scope of patent protection that the utility model is determined by the claims submitted.
