Specifically, the limiting ring 131 may be disposed near the opening of the slot 11, the magnetic component 14 is disposed on a side of the limiting ring 131 away from the opening of the slot 11, so that the limiting ring 131 is disposed between the opening of the slot 11 and the magnetic component 14, the limiting ring 131 may be a magnetizer, a magnetic attraction force is formed between the magnetic component 14 and the limiting ring 131, and further a pulling force is formed on the first transmission member 12 so that the first elastic member 132 is compressed, the first elastic member 132 generates elastic potential energy in a compressed state, and the first elastic member 132 may be specifically made of an elastic polymer material such as a spring or rubber.

The first movable member 141 of the magnetic assembly may be a permanent magnet made of a magnetic material, the curie temperature point Tc of the magnetic material is set to be the first temperature T1, when the charging plug 2 charges the device main body 1, if an abnormal condition such as a short circuit, a micro short circuit or long-term overcharge occurs, the temperature of the charging plug 2 rises and reaches the first temperature T1, at this time, the magnetism of the magnetic assembly is weakened (the high-temperature magnetism of the magnetic material is weakened, the normal-temperature magnetism is recovered), the elastic potential energy when the first elastic member 132 is compressed pushes the first transmission member 12 to a direction approaching to the charging plug 2 when no magnetic attraction constraint exists, so that the charging plug 2 is separated from the slot 11, and the charging plug 2 can pop out, thereby disconnecting the charging circuit, avoiding the damage of the device main body 1 due to the continuous rising of the temperature, and achieving the purpose of protecting the device main body 1 and the charging plug 2.

At this time, the two poles of the first movable member 141 are opposite to the non-conductive body 1423, and the first movable member 141 has the weakest external magnetic property, that is, is in the off position.

Specifically, when the charging plug 2 charges the apparatus body 1 at a temperature lower than the first temperature, the magnetic attraction force of the magnetic member 142 to the first magnetizer 1411 is F1, the second elastic member 1412 is in a stretched state, and the pulling force of the second elastic member 1412 to the first magnetizer 1411 is F2. The limit stop 16 may include two limiting blocks oppositely disposed in the guide rail 15, a gap is reserved between the two limiting blocks for the first transmission member 12 to pass through, one sides of the two limiting blocks facing the first magnetizer 1411 are arc surfaces, an annular groove is disposed on the first transmission member 12, balls disposed between the limiting blocks and the first magnetizer 1411 may be steel balls, when the first magnetizer 1411 approaches the magnetic member 142 under the action of F1, the steel balls are pressed to move toward the guide rail 15, and when the steel balls abut against the arc surfaces of the limit stop 16 and are located in the annular groove, a self-locking state is formed, at this time, although the first elastic member 132 is in a compressed state, the first transmission member 12 cannot be ejected by the elastic force F3 of the first elastic member 132 on the limiting ring 131 and the first transmission member 12, as shown in fig. 21. When the temperature of the charging plug 2 is greater than or equal to the first temperature, that is, the temperature of the charging plug 2 exceeds T1, the magnetism of the temperature limiting assembly 14 is weakened, even 0, and at this time F1 is smaller than F2, the first magnetizer 1411 moves away from the limit stop 16 under the action of the pulling force F2 of the second elastic member 1412, the steel balls are separated from the annular groove, the first transmission member 12 extends outwards under the action of the elastic force F3 of the first elastic member 132, and the charging plug 2 is separated from the slot 11, as shown in fig. 22.
