Abstract

The invention discloses a cross-shaped high-power spring resistor which comprises a center block, a connecting column, a bridging connecting strip, a supporting mechanism, a heat dissipation plate, anano carbon powder layer, a resistance wire, a fixing groove, a first fixing bolt and a first connecting plate. The two sides of the top end of the center block are fixedly connected with die fixing pieces correspondingly, and the die fixing pieces are fixedly connected with the connecting columns through second fixing bolts. The outer surface of the center block is connected with the resistance wire through the fixing groove, the resistance wire is obliquely wound on the outer surface of the center block, the cross sectional area of the resistance wire is increased, the efficiency of the resistor is improved, a plurality of heat dissipation plates are arranged on the center block and distributed on the center block at equal intervals, and the two sides of each heat dissipation plate are fixedly connected with nano carbon powder layers. The nano carbon powder layer is composed of a nano carbon powder material, has a good heat dissipation effect, can effectively dissipate heat of the resistor, improves the working efficiency of the resistor, and prolongs the service life of the resistor.

Description

technical field [0001] The invention relates to the field of spring resistor preparation, in particular to a cross-shaped high-power spring resistor and a preparation process thereof. Background technique [0002] When the charge moves in the conductor, it will be collided and rubbed by other particles such as molecules and atoms. As a result of the collision and friction, the conductor hinders the current. The most obvious feature of this hindrance is that the conductor consumes electric energy and generates heat. This hindering effect of the current is called the resistance of the object. The resistor is generally called the resistance directly in daily life. It is a current limiting element. After the resistor is connected to the circuit, the resistance value of the resistor is fixed, generally Two pins, which can limit the current through the branch it is connected to, the resistance cannot be changed is called a fixed resistor, and the variable resistance is called a po...
