Problems solved by technology

[0002] A relay is an electrical appliance that switches on or off a control circuit according to a change in an input signal to achieve control. The input signal of the relay can be electric current, voltage, etc., or it can be temperature, speed, time, pressure, etc. Electricity, and the output is usually the on or off action of the contact. The relay is generally not used to directly control the main circuit with a large current, but to control the main circuit through a contactor or other electrical appliances. There are many types of relays according to their The application can be divided into control relay and protection relay; according to the action time, it can be divided into instantaneous relay and delay relay; according to the working principle, it can be divided into electromagnetic relay, inductive relay, electric relay, thermal relay and electronic relay, among which electromagnetic relay It is widely used because of its stable properties, but the common electromagnetic relays on the market currently have the following defects, 1) the overall structure is complex, the cost is high, 2) the sensitivity is poor, and the response is lagging; therefore, there is an urgent need for a new Technical solutions to solve the above technical problems

Embodiment 1

[0014] Example 1 : see figure 1 , a high-efficiency electromagnetic relay, the electromagnetic relay includes an electromagnetic mechanism and a contact system, the contact system is arranged on the electromagnetic mechanism, the electromagnetic mechanism includes an iron yoke 8, an iron core 10, a coil 9 and a pole shoe 5, The iron yoke 8 is configured as a U-shaped structure, the iron core 10 is fixed on the bottom of the iron yoke 8 , coils 9 are arranged on both sides of the iron core 10 , and the pole shoes are arranged on the iron core. The whole structure of the device is ingeniously designed, compact and low in cost, and the electromagnetic relay has sensitive response and good stability.

Embodiment 2

[0015] Example 2 : see figure 1 , as an improvement of the present invention, the electromagnetic mechanism also includes a first bracket 11 and a second bracket 12, the first bracket 11 is arranged on the upper part of the inner side of the U-shaped iron yoke 8, and the second bracket 12 Fix the bottom of the other side of the U-shaped iron yoke 8 outside. The first bracket 11 and the second bracket 12 strengthen the stability of the combination of the static contact 1 and the movable contact 2, so that the sensitivity is higher. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0016] Example 3 : see figure 1 , as an improvement of the present invention, the contact system includes a static contact 1, a movable contact 2, an armature 4, and a reaction force spring 7, the static contact is arranged on the first bracket, and the armature is fixed On the inner side of one side of the U-shaped iron yoke, the reaction force spring is arranged between the armature and the second bracket, a reed is arranged on the upper part of the armature, and the other end of the reed is connected to the movable contact. The rest of the structures and advantages are exactly the same as in Embodiment 1.
