Embodiment 1

[0056] This embodiment provides an action mechanism of the 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 member , 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 tripping ...

Embodiment 2

[0074] This embodiment provides an actuating mechanism of an electric 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 The first push rod 21 , the second push rod 22 and the third push rod 23 are fixed on the installation cap for the rotating shaft 20 to rotate.

Embodiment 3

[0076] This embodiment provides an actuating mechanism of an electric 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, the second recess corresponding to the first recess is arranged 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 first recess. Two pits, the shaft 20 can rotate relative to the first pit and the second pit, 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 an action mechanism of a leakage protection module, including a base, a traction member, and a tripping actuator; and a reset member, which can move on the base under the action of an external force, and has a first matching portion and a first elasticity. The first matching part is provided with an acceleration tripping part; the tripping actuating part has a second push rod, and the second push rod has a second matching part. When there is no leakage, the first matching part cooperates with the second matching part to Make the tripping actuating part static, and the first elastic part is in a state of energy storage; when there is a leakage, the tripping actuating part drives the second push rod to rotate under the action of the traction part, so that the first matching part and the second matching part are slid away from each other, At this time, the energy released by the first elastic member gives the reset member an external force to make the reset member move on the base, which drives the acceleration release member to act, urges the acceleration release member to abut against the second push rod and gives the second push rod a rotational actuation force. The direction of the rotational actuation force is basically the same as the direction in which the second push rod rotates under the action of the traction member.

Description

technical field [0001] The invention relates to a leakage circuit breaker, in particular to an action mechanism of a 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 least on...
