Abstract

The invention provides a time-varying resistor, comprising: a rotating handle, a resistor body, a sliding metal contact, and a guide rod, the axis of the rotating handle is connected to the first end of the guide rod, and the guide rod The second end of the rod is connected to the sliding metal contact, and the sliding metal contact is in electrical contact with the resistor body. The resistor also includes a time-varying elastomer that changes the position of the sliding metal contact over time. This technical solution uses hairsprings as elastic elements on the basis of variable resistors, so that the output resistance of the resistors can be continuously and linearly adjusted with time, fully meeting the needs of stable and safe operation in specific places such as motor starting and speed regulation.

Description

technical field [0001] The invention relates to the field of electronics and electrics, and is applied to the fields requiring the connected resistance to change with time, such as motor starting and speed regulation, electrical equipment used under severe environmental conditions, and the like. Background technique [0002] The resistance value of the variable resistor can be adjusted, and the resistance can be changed by changing the length of the resistance wire connected to the circuit part. Connecting variable resistors in the circuit can adjust the size of the current and the voltage division of the components in the circuit. The temperature of the electric iron, the brightness of the light, the volume of the speaker, the speed of starting the motor or controlling it, etc. are all connected in series with variable resistors in the circuit to achieve adjustment. [0003] A variable resistor consists of a resistive body and a turning or sliding system. On the exposed r...
