Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
The resistor of the present embodiment is as shown in Figure 1, Figure 2 and Figure 3, including 2, two blocks of two end plates 1, resistive mode group side plates 3
The demarcation plate 4 to insulate with two pieces, resistive mode group 2 include the resistor stripe 22 of three pieces of support plates 21 being arranged in juxtaposition and eight hard,
The end of every resistor stripe 22 is connected with elbow 5, realizes that mutually string is simultaneously between eight resistor stripes 22 by this plurality of elbow 5
Connection.For support plate 21 using insulation mica material, insulation high-temperature-resistant performance is good.Two pieces of demarcation plates, 4, two blocks of side plates 3 and support plate 21
It being arranged in juxtaposition, for demarcation plate 4 between side plate 3 and resistive mode group 2, two end plates 1 have a card hole 11, and the two of demarcation plate 4
End is equipped with card convex 41 compatible with card hole 11, and the both ends of support plate 21 are equipped with card convex 212 compatible with card hole.Two blocks of side plates
Two end plates 1 are fixed on using bolt and nut respectively in 3 both ends, thus make support plate 21, demarcation plate 4 and two blocks of side plates 3 it
Between position be fixed to each other.
In conjunction with shown in Fig. 4 and Fig. 5, each support plate 21 is provided with the strip hole 211 of eight rows, the same position of different support plates 21
The strip hole 211 set is mutually aligned.Every resistor stripe 22 is an integral molding structure and continuous bend forms multiple U bend sections, electricity
Each U bend section of resistance item sequentially passes through the strip hole 211 of the alignment of this three pieces of support plate 21.Phase in the same support plate 21
Adjacent two rows of strip holes 211 are staggered in the longitudinal direction, to increase the insulation distance between adjacent two resistor stripes 22.Strip hole
211 length is slightly less than the width of U bend section, so that U bend section flexibly resists the hole wall of strip hole 211, it is whole in this way
