Embodiment 1

[0056] This embodiment provides an action mechanism of a novel leakage protection module, such as Figure 1-2 As shown, it includes: a base 4; a traction member 1, which is installed on the base 4, and operates when leakage occurs; a tripping actuator 2, which is installed on the base 4, and is controlled by the traction member 1. The action rotates, and then triggers tripping; it also includes a reset member 3, which is installed on the base 4, and can move on the base 4 under the action of an external force, and has a first matching part and a first elastic part , the first matching portion is provided with an accelerated release member; the tripping actuator 2 has a second push rod 22, and the second push rod 22 has a second matching portion. When there is no leakage, the first matching part cooperates with the second matching part to make the tripping actuator 2 stationary, and the first elastic member is in the state of energy storage; when there is a leakage, the trippin...

Embodiment 2

[0074] This embodiment provides an action mechanism of a new leakage protection module, which is a modification of Embodiment 1. In this embodiment, the rotating shaft 20 is fixed on the base 4, and the rotating shaft 20 is provided with a relatively The rotating shaft 20 is mounted on a cap on which the first push rod 21 , the second push rod 22 and the third push rod 23 are fixed.

Embodiment 3

[0076] This embodiment provides an action mechanism of a new leakage protection module, which is a modification of Embodiment 1. In this embodiment, a first recess is provided on the base 4, and one end of the rotating shaft 20 is installed into the The first recess is described above, and the second recess corresponding to the first recess is provided on the cover that cooperates with the base 4 to cover the entire tripping mechanism, and the other end of the rotating shaft 20 is installed into the The second pit, the shaft 20 can rotate relative to the first pit and the second pit, and the first push rod 21 , the second push rod 22 and the third push rod 23 are fixed on the shaft 20 .

Abstract

The invention provides a novel action mechanism of an electrical leakage protection module. The novel action mechanism comprises a base, a traction piece and a tripping actuating piece. The novel action mechanism also comprises a reset piece which can move on the base under the effect of an external force and is provided with a first matching portion and a first elastic element, wherein the first matching portion is provided with an acceleration tripping piece; the tripping actuating piece is provided with a second push rod; the second push rod is provided with a second matching portion; when no electric leakage occurs, the first matching portion is matched with the second matching portion such that the tripping actuating piece is immobile, and the first elastic element is in an energy storage state; when electric leakage occurs, the tripping actuating piece drives the second push rod to rotate under the effect of the traction piece, such that the first matching portion can be separated from the second matching portion in a sliding manner, at this moment, the first elastic element releases energy so as to apply an external force to the reset piece such that the reset piece can move on the base; the reset piece drives the acceleration tripping piece to move and force the acceleration tripping piece to abut against the second push rod such that a rotation actuating force can be to applied to the second push rod; and the direction of the rotation actuating force is basically the same as the direction of the rotation of the second push rod caused by the effect of the traction piece.

Description

technical field [0001] The invention relates to a leakage circuit breaker, in particular to an action mechanism of a novel leakage protection module. Background technique [0002] The circuit breaker is an essential device to ensure the safety of electricity consumption and circuit switching, and can protect electrical equipment and personal safety. The leakage circuit breaker installed in the electrical circuit, when the leakage current reaches the rated value, its current signal is detected and amplified by the electronic circuit, and the electromagnet coil is turned on to generate a magnetic field, which drives the iron core to move, and through the lever and other mechanisms, the moving The contacts and static contacts are tripped, and then the tripped state is self-locked to keep the circuit safe. [0003] Chinese patent document CN201355599Y discloses a tripping mechanism of a circuit breaker, which includes a draw bar and a locking member. The draw bar includes at le...
