Technical Field

The invention belongs to the field of low-voltage electrical appliances, and particularly relates to a grounding device of a leakage protection circuit breaker.

Background

The current leakage protection circuit breaker commonly used in the market only has the functions of overcurrent, short circuit and leakage protection of loads, the protection capability of the external surge generated due to thunder and lightning is lost, and if the problems are solved, a surge protector is required to be connected in parallel on a main circuit of the leakage protection circuit breaker to play a protection role. If a surge protector is connected in parallel, the required installation position is necessarily increased.

If with the inside of surge protector integration to earth leakage protection circuit breaker, set up a earthing device on earth leakage protection circuit breaker body, just need not to lead to earth leakage protection circuit breaker's outside with surge protection's earth connection again, carry out the ground connection and connect. The ground wire of the surge protector is connected with the grounding device only inside the leakage protection breaker body, and then the surge protector is connected with the ground through the grounding device.

Therefore, the grounding device of the leakage protection circuit breaker provided by the invention can conveniently finish the grounding work of the leakage protection circuit breaker. Particularly, under the condition of installing a plurality of earth leakage circuit breakers, all the earth leakage circuit breakers are installed on the installation support, and then the metal parts of the installation support are subjected to one-time grounding treatment, so that each earth leakage circuit breaker does not need to be connected with the ground, and the grounding workload of the earth leakage circuit breakers is greatly reduced.

Disclosure of Invention

In order to achieve the purpose, the invention discloses a grounding device of an electric leakage protection circuit breaker, wherein the grounding device is arranged at the position of a clamping groove at the bottom of the electric leakage protection circuit breaker; one end of the grounding device causes the inside of the leakage protection circuit breaker body to be connected with the ground wire of the circuit unit, and the other end of the grounding device is in contact conduction with the metal part of the mounting bracket. The grounding device is in contact conduction with the metal part of the mounting bracket by adopting a spring or a spring sheet, and can also be in contact conduction with the metal part of the mounting bracket by adopting two combined modes.

The invention also provides another grounding device of the leakage protection circuit breaker, which is characterized in that the material of the elastic buckle of the leakage protection circuit breaker is replaced by a conductive material, and a conductor is connected on the elastic buckle, so that the inside of the leakage protection circuit breaker body is connected with the ground wire of the circuit unit.

The invention has the advantages that: the grounding device is arranged on the leakage protection circuit breaker body, so that the grounding work of the leakage protection circuit breaker can be conveniently completed. Particularly, under the condition of installing a plurality of earth leakage circuit breakers, all the earth leakage circuit breakers are installed on the installation support, and then the metal parts of the installation support are subjected to one-time grounding treatment, so that each earth leakage circuit breaker does not need to be connected with the ground, and the grounding workload of the earth leakage circuit breakers is greatly reduced.
