Resistor with resistor monomers capable of being connected in series or in parallel

Abstract

The invention relates to a resistor with resistor monomers capable of being connected in series or in parallel, and the resistor comprises a square frame-shaped seat frame, an insulating seat, a middle insulating seat, a terminal insulating seat, an insulating connecting seat, a square connecting rod with screw rods at two ends, a nut and a plurality of resistor monomers, wherein a resistor groupis disposed between a top transverse frame plate and the square connecting rod; the pin columns of the insulating seats on the top transverse frame plate are inserted into the wave crest holes of theresistor single bodies, and the upper pin bodies of the middle insulating seats are inserted into the wave trough holes; the other resistor group is arranged between the square connecting rod and thebottom transverse frame plate, the lower pin body is inserted into the trough hole of the resistor monomer, and the pin body of the insulating seat on the bottom transverse frame plate is inserted into the crest hole; a terminal plate of the resistor monomer extends out of a terminal plate hole of the terminal insulating seat; and the resistor monomers are distributed in rows and columns. Due to the adoption of the structure, the resistor single bodies adopt the distribution mode, the size is reduced, and the resistor single bodies are formed by bending the battens, so the heat dissipation performance is good; one row of resistor monomers can be connected in parallel, and the same column of resistor monomers can be connected in series.
