Description

The present invention relates to a multi-coil relay, and more particularly, to a multi-coil relay that has an electromagnetic structure of a plurality of coils, reduces the wear efficiency of the coil, and achieves the effect of improving the electromagnetic efficiency.

A relay is an electronic control member that has a control system (or input circuit) and a controlled system (or output circuit), and relays are usually applied in automatic controllers, whose characteristics are: Since it is an “automatic switch” that uses a relatively small current and controls a relatively large current, the relays in the circuit are usually applied to automatic adjustment, safety protection, conversion circuits, and the like.

Based on the structure and operating characteristics, the relay is generally composed of two parts, an input sensor mechanism and an output execution mechanism. The input sensor mechanism is used to react to a change in the sensor input amount. Speaking of relays with contacts, the relay operation is performed by dividing the contacts, and for relays without contacts, the relay operation is performed by conducting and disconnecting the semiconductor member. The relay is a jumping input. -With output characteristics, when the relay receives one input signal, when the input signal is smaller than the operating value set by the relay, the relay does not operate, and when the input signal reaches the operating value set, the relay Operates, connects to the circuit contact of the relay output execution mechanism, immediately changes from 0 to the signal potential that meets the requirements, and after the relay operates, the input signal attenuates downward from the high point The output execution mechanism will not return to zero in the linear manner, and the relay will immediately turn off the output execution mechanism at the moment when the input signal decays until it becomes smaller than the operating value. To change.

  Relays can be classified into electromagnetic relays, thermal relays, solid state relays, etc., depending on their structural characteristics. Among them, electromagnetic relays are generally composed of iron cores, coils, magnetic poles, spring pieces, etc. In addition, an electromagnetic reaction is generated in the current flowing in the coil, and the magnetic pole can overcome the pulling force of the returning spring and move toward the iron core to perform circuit conduction and switching.

  However, since the magnetic coils used in the conventional electromagnetic relays all adopt a single coil system, the magnetic poles can be sucked by the same current generated by the coils in a situation where the voltage at the input end is not changed. A larger magnetic force must be generated, and the general method is to increase the number of turns of the coil or the entire length of the coil when the diameter of the enamel wire is increased. Such a scheme is disadvantageous for the installation of small relays because the overall width or length of a single coil becomes too large.

  In view of the drawbacks of conventional electromagnetic relays that employ a single coil, the overall width or length of the coil tends to be excessive, the present invention developed a multi-coil relay, and the magnetic strength of the relay was increased by installing the multi-coil relay. Increasingly, single coil magnetic relays overcome the drawbacks that the overall width or length of the coil tends to be excessive.
