Detailed description of the invention

With reference to drawings and Examples, this utility model one chopper is described further.

A kind of chopper; including breaker body 1; also include external earth leakage protective device, for making micro-control switch 2, the protective housing 3 that in breaker body 1, combined floodgate circuit disconnects; described earth leakage protective device electrically connects with micro-control switch 2; and it being placed in protective housing 3, described protective housing 3 is detachably fixed with breaker body 1 and is connected. Earth leakage protective device is arranged on the outside of breaker body 1, makes the original internal mechanism of breaker body 1 to change. The outer wall of the relative protective housing 3 of breaker body 1 offers hole, location, described protective housing 3 is convexly equipped with the projection for coordinating with hole, location.

Protective housing 3 protects what several were set up in parallel to mould shell housing; what be placed in two ends is a plastic casing 31; remaining is No. two plastic casings 32; all plastic casings are spliced to form the cavity volume placed for earth leakage protective device; and be connected fixing with nut by bolt-through, described micro-control switch 2 is arranged on inside a plastic casing 31 of circuit breakers body 1.

Protective housing 3 is detachably fixed connection by bolt.

Also including a plastic casing 31 clamping of connector 4, described connector 4 one end and circuit breakers body 1, the other end is detachably fixed with breaker body 1 by screw and is connected. Connector 4 one aspect plays the effect connecting breaker body 1 and protective housing, on the other hand, also acts as the electric wire that protective breaker body 1 is connected with earth leakage protective device. Being provided with draw-in groove in number plastic housing 31 body of circuit breakers body 1, it is fast that one end of the relative plastic casing 31 of described connector 4 is provided with card.

Micro-control switch 2 includes coil 21, yoke frame 22, iron core 23, button 24, compress spring 25 and for touching the driving member 26 of reset buckle in breaker body 1, described coil 21 is fixed on yoke frame 22, compression spring 25 and iron core 23 are sequentially inserted in the endoporus of coil 21 shaft core position, described iron core 23 relatively compresses the other end of spring 25 and is flexibly connected with driving member 26, driving member 26 pivot pin is fixedly connected on the inwall of a plastic casing 31, described button 24 is placed in the opposite side of driving member 26 opposed coil 21, its one end is flexibly connected with driving member 26, the other end extends to outside a plastic casing 31.

Earth leakage protective device is the external outside at Shell of circuit breaker, covered by protective housing 3 and be detachably fixed by bolt with short-circuiting device protective housing 3 and be connected, and protective housing 3 is to be spliced to form by several plastic casings, so, assemble more convenient, save installation time. when there is leaky in circuit, the difference of front and back electric current is sensed by the mutual inductor 21 in earth leakage protective device, signal is passed to micro-control switch 2, coil 21 produces electromagnetism, iron core 23 extruding compression spring 25 shrinks in the endoporus with coil 21, iron core 23 pulls driving member 26 to rotate, driving member 26 touches the reset buckle in breaker body 1, moving contact in breaker body 1 is made to separate with static contact, circuit disconnects, now, button 24 separates with driving member 26, the other end of button 24 is jumped out from a plastic casing 31, when shift knob in breaker body 1 to rotate, need to reset the button 24 in micro-control switch 2, therefore, may also operate as the effect of enlightenment and fool proof effect. buckle and card slot fit play pre-aligned effect, further facilitate assembling.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model. It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
