Description
Technical field
The utility model relates to a kind of resistor field, particularly relates to a kind of efficient resistor by multi-disc resistance punching stack combinations.
Background technology
Various resistors are arranged in prior art, for example wherein a kind of constantan wire Shi Tie Chrome aluminium flake is given the resistor of system, be at present as more common a kind of resistors such as the startup of motor, braking, speed governing, it has, and structure property is poor, poor stability, easy aging, the shortcoming such as volume is large, useful life is short.
The utility model content
The purpose of this utility model is in order to solve deficiency of the prior art, and the stack combinations by its resistance punching provides a kind of stability strong now, anti-aging strong, volume is little and the resistor of long service life.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of resistor, comprise fixed head, connecting plate, screw rod and at least two resistance punching, it is characterized in that, described screw rod is fixedly connected on fixed head by hold-down nut, offer connecting hole in described resistance punching, screw rod runs through the resistance punching by connecting hole is fixed on fixed head it, and is provided with insulator between the resistance punching, described insulator is enclosed within on screw rod, and makes directly isolation mutually of two resistance punchings; Described resistance punching is cascaded by connecting plate, and the resistance punching is connected according to its resistance value classification successively;
Above-mentioned a kind of resistor is characterized in that: described resistance punching is the stainless steel punching, and the connecting through hole of described resistance punching is on four four knuckles that are placed in respectively the resistance punching;
Above-mentioned a kind of resistor is characterized in that: be provided with grid in described resistance punching, and the thickness of resistance punching is 0.5～1.2mm;
Above-mentioned a kind of resistor is characterized in that: also comprise a terminal block, described terminal block and resistance punching are by being welded to connect;
Above-mentioned a kind of resistor is characterized in that: described insulator material is pottery.
The beneficial effect that the utlity model has: adopt stainless resistance punching as resistive element, take full advantage of nichrome material corrosion resistant turbid, without advantages such as earth resistance, resistance are stable, volume is little, long service life; Mechanical strength is high, and not fragile, service time is long, and attractive in appearance, light and handy, high temperature resistant, be difficult for oxidation, power frequency is high temperature resistant, resistance error is little and stable performance, punching cost are low.Overcome former resistor with constantan wire formula siderochrome aluminium flake, resistance poor performance, poor stability, easy aging, shortcomings such as volume large, useful life.
