As shown in fig. 1, the electromagnet system is mounted on the seat plate 5 and is located in the housing 1 (located in a sealed cavity between the housing 1 and the seat plate 5), and the electromagnet system includes a coil 12, an iron core 3, an iron yoke 2, an armature 10, and two connection tabs 4.

The coil 12 is mounted on the seat plate 5 and generates a magnetic field when energized.

The iron core 3 is sleeved in the coil 12, and both ends of the iron core extend out of the coil 12.

The iron yoke 2 is of an L-shaped structure, the vertical section of the iron yoke 2 is vertically arranged on the seat board 5 and fixedly connected with the left end of the iron core 3, the horizontal section of the iron yoke 2 is positioned above the coil 12 and points to the right end of the iron core 3, and a hook is arranged on the horizontal section of the iron yoke 2.

The armature 10 is movably arranged on the right side of the iron core 3 (corresponding to the right end position of the iron core 3) and can be attracted to or separated from the right end of the iron core 3.

The two wiring lugs 4 are arranged on the seat board 5, the upper ends of the two wiring lugs 4 are respectively connected with two connectors of the coil 12, the lower ends of the two wiring lugs 4 extend out of the seat board 5 and can be connected or disconnected with an external power supply, and the coil 12 is controlled to be electrified or powered off through the connection or disconnection of the wiring lugs 4 and the external power supply, so that whether the armature 10 and the iron core 3 are magnetized or not is controlled, and the armature 10 and the iron core 3 are attracted or separated.

As shown in fig. 1, the contact system is also mounted on the seat plate 5 and is located in the housing 1 (in a sealed cavity between the housing 1 and the seat plate 5), the contact system is arranged on the right side of the electromagnet system (coil 12), and the contact system comprises two groups of contact mechanisms, a spring leaf 11 and a movable spring leaf 9. Each group of contact mechanisms comprises a busbar 6, a fixed contact 7 and a movable contact 8.

The bus plate 6 is arranged on the seat plate 5, and the lower end of the bus plate 6 extends out of the seat plate 5 to be connected with a load.

The stationary contact 7 is connected (riveted) to the busbar 6.

The movable contact 8 is movably arranged at the side (right side) of the fixed contact 7 and can be folded or separated with the fixed contact 7, so that the movable contact is connected or disconnected with the fixed contact 7.

The two ends of the reed 11 are respectively connected (riveted) to the movable contacts 8 of the two sets of contact mechanisms and conduct the two movable contacts 8.

One end of the movable reed 9 is respectively connected (riveted) with the movable contacts 8 of the two groups of contact mechanisms, the other end of the movable reed 9 is connected to the hook of the iron yoke 2, and the middle part of the movable reed 9 is fixedly connected with the armature 10.

Working principle:

As shown in fig. 1, when the lug 4 is energized (an external power supply is turned on), the coil 12 is energized and generates an electromagnetic field, the iron core 3 and the armature 10 are magnetized, the iron core 3 attracts the armature 10, so that the armature 10 drives the movable spring 9, the spring 11 and the movable contact 8 to move towards the direction of generating the fixed contact 7 until the movable contact 8 and the fixed contact 7 are in contact conduction, at this time, the movable contact 8 is in conduction with the busbar 6, and finally the busbars 6 of the two groups of contact mechanisms are in conduction with each other, the load is conducted, the load is electrically operated, and the working channel of current is formed: one group of contact mechanisms (bus sheet 6, fixed contact 7, movable contact 8), movable reed 9, reed 11, movable reed 9 and the other group of contact mechanisms (movable contact 8, fixed contact 7 and bus sheet 6), namely when the wiring sheet 4 is powered on, a movable contact loop and a fixed contact loop are connected, and a contact loop is closed, so that a product is converted into a closed state from opening.

When the wiring lug 4 is powered off, the electromagnetic field generated by the coil 12 disappears, the magnetic force of the iron core 3 and the armature 10 disappears, the attractive force generated by the iron core 3 and the armature 10 disappears, the movable spring 9 drives the armature 10, the movable contact 8 and the spring 11 to move in the direction away from the fixed contact 7 under the counter force action until the movable contact 8 and the fixed contact 7 are blocked by the seat board 5 (or the housing 1), the movable spring 9 returns to the initial position, the contact circuit is opened, and the product is converted into an open state from a closed state.

When the relay is in the off state, the voltage at the two ends of the coil 12 is gradually increased, the relay is switched from the off state to the on state, and after the relay is in the on state, the contact circuit is switched on. The voltage at the two ends of the coil 12 is gradually reduced, the relay is converted into an off state from an attracting state, the seat board 5 limits the movement of the movable reed 9, the movable reed 9 returns to the original position, and a contact circuit is disconnected, so that the state conversion of the relay is realized.

The present embodiment makes the following settings on the basis of embodiment 1:

As shown in fig. 2, a magnetic steel 13 for arc blowing is installed in the housing 1.
