Connector and contactor assembly

Abstract

The invention discloses a connector and a contactor assembly. The connector is provided with a control circuit, and the control circuit is connected to a coil in a contactor and is used for controlling operations of the contactor; the control circuit includes a work control circuit for supplying work current to the contactor; the work control circuit includes a PWM power saving circuit which is connected to the contactor; when the contactor powers on, the PWM power saving circuit provides a signal with a preset duty ratio to the contactor (20); after the contactor (20) powers on, the PWM power saving circuit maintains that the PWM power saving circuit provides a signal with a small duty ratio to the contactor during the condition of power-on of the contactor (20) to reduce the power consumption. According to the connector and the contactor assembly, the PWM power saving circuit is integrated into the connector, so that the average drive current of the contactor is reduced, and the size of the contactor is reduced.

Description

technical field [0001] The present invention relates to a connector and a contactor assembly, and more particularly to a contactor, and a connector for connecting a coil in the contactor and controlling the operation of the coil. Background technique [0002] Contactors or relays are usually used to switch or control working circuits. For example, the contactor is provided with a coil and dynamic and static contacts. When current passes through the contactor coil, a magnetic field can be generated to close the dynamic and static contacts to control the load electrical appliances. [0003] Due to frequent switching on and off, the current conduction contacts of high-voltage and high-current contactors or relays will cause welding adhesion due to reasons such as overcurrent, high-temperature arc damage, or long-term application aging, so that the moving contacts of contactors or relays Ineffective out of control. For low voltage relays or contactors, general circuits can si...

AI Technical Summary

Problems solved by technology

This method is simple for client applications, but the cost of contactors and product maintenance is relatively high

In addition, when the contactor or relay is combined with multiple control circuits, the wiring and connection of the circuit become complicated, which leads to an increase in the cost of the contactor or relay

At the same time, in the process of miniaturization, simplification, and generalization of contactors or relays, the development of diversification of contactors or relay control circuits is bound to be limited.
