the electromagnetic mechanism is arranged above the contact mechanism through a bracket 14 fixed on the base 3; the electromagnetic mechanism comprises a yoke 15 fixed on the upper part of the bracket 14, an iron core 16 and a coil 17 horizontally arranged between the yoke 15, and an armature 18 hinged on the lower part of the bracket 14 through a shaft bracket 21, wherein the armature 18 is positioned below the yoke 15; a magnetic steel 19 is fixed above the armature 18, a pushing reed 20 is fixed below the armature 18, and the pushing reed 20 is positioned right above the push rod 10; two leading ends of the coil 17 are electrically connected to the two input terminals 2, respectively.
The cover 1 is composed of a cover shell 22 connected to the periphery of the base 3 in a welding and sealing mode and an upper cover plate 23 connected to an upper port of the cover shell 22 in a welding and sealing mode; the input terminal 21 is fixed to the upper cover plate 23 by glass sealing. The upper cover plate 23 is provided with a fabrication hole 24, air in the cover 1 is pumped out through the fabrication hole 24 and then argon is injected, and then the fabrication hole 24 is sealed through a spot welding sealing steel ball 25, so that the overall sealing of the relay is realized.
In one embodiment. The belt-shaped cavity 4 is of a groove structure with two semicircular ends, and three through holes 5 and two counter bores 6 are uniformly distributed at the bottom of the groove. The push rod 10 is formed by connecting an upper push rod and a lower push rod, the movable spring leaf 12 is clamped between the upper push rod and the lower push rod, the upper push rod is located in a through hole of the lower cover plate 13, and the structure is convenient to assemble and debug.

The working principle is as follows: when rated voltage is input to the coil 17, an electromagnetic field generated by the coil 17 is overlapped with a magnetic field of the permanent magnetic steel 19, one end of the armature 18 forms magnetic field superposition, and the other end forms magnetic field cancellation. When the difference between the two ends of the armature 18 is larger than the magnetic holding force of the magnetic steel 19, the armature 18 rotates from the offset end to the superimposed end. At one end of the superposed magnetic field, the yoke 15 is attracted with the armature 18, so that the corresponding push reed 20 is separated from the push rod 10, the push rod 10 is pushed by the elasticity of the spring 11 to move upwards, so that the corresponding movable reed 12 is separated from the static reed 8, and the disconnection of the contact is realized; at the end where the magnetic field is cancelled, the yoke 15 is separated from the armature 18, so that the corresponding push spring 20 is contacted with the push rod 10, and the push rod 10 overcomes the counter force of the spring 11 to move downwards, so that the corresponding movable spring 12 is contacted with the static spring 8, and the contact closing is realized.
When the coil 17 is de-energized, the relay keeps the energized state unchanged. When the coil 17 is reversely excited, the electromagnetic field generated by the coil 17 and the magnetic field of the permanent magnet steel 19 are mutually reversely overlapped, and the relay returns to the initial state.
