Description
Technical field
This utility model relates to a kind of electric switch, more specifically, it relates to a kind of chopper.
Background technology
At present, the chopper on market, it includes Shell of circuit breaker, is provided with earth leakage protective device, overload protection arrangement in Shell of circuit breaker.This chopper is because earth leakage protective device, overload protection arrangement are installed in narrow and small Shell of circuit breaker, and the component part that two earth leakage protective devices close overload protection arrangement is more, and therefore, assembling is inconvenience comparatively, and assembling effect is relatively low.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of chopper solving the problems referred to above.
For achieving the above object, this utility model provides following technical scheme:
A kind of chopper; including breaker body; also include external earth leakage protective device, for making micro-control switch, the protective housing that in breaker body, combined floodgate circuit disconnects; described earth leakage protective device electrically connects with micro-control switch; and it being placed in protective housing, described protective housing is detachably fixed with breaker body and is connected.
This utility model is further arranged to: described protective housing protects what several were set up in parallel to mould shell housing; what be placed in two ends is a plastic casing; remaining is No. two plastic casings; 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 is arranged on inside a plastic casing of circuit breakers body.
This utility model is further arranged to: described protective housing is detachably fixed connection by bolt.
This utility model is further arranged to: also include connector, a plastic casing clamping of described connector one end and circuit breakers body, and the other end is detachably fixed with breaker body by screw and is connected.
This utility model is further arranged to: described micro-control switch includes coil, yoke frame, ferrum core, button, compress spring and for touching the driving member of reset buckle in breaker body, described coil is fixed on yoke frame, compression spring and iron core are sequentially inserted in the endoporus of coil shaft core position, described iron core relatively compresses the other end of spring and is flexibly connected with driving member, driving member pivot pin is fixedly connected on the inwall of a plastic casing, described button is placed in the opposite side of driving member opposed coil, its one end is flexibly connected with driving member, the other end extends to outside a plastic casing.
By adopting technique scheme; earth leakage protective device is the external outside at Shell of circuit breaker; covered by protective housing and be detachably fixed by bolt with short-circuiting device protective housing and be connected; and protective housing 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 in earth leakage protective device, signal is passed to micro-control switch, coil generating electromagnetic, in the endoporus of iron core extruding compression spring contraction and coil, iron core pulls driving member to rotate, driving member touches the reset buckle in breaker body, moving contact in breaker body is made to separate with static contact, circuit disconnects, now, button separates with driving member, the other end of button is jumped out from a plastic casing, when shift knob in breaker body to rotate, need the push-button reset in micro-control switch, therefore, may also operate as the effect of enlightenment and fool proof effect.

Detailed description of the invention
With reference to drawings and Examples, this utility model 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.
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 and connects breaker body 1 and include the effect of housing, on the other hand, also acts as the electric wire that protective breaker body 1 is connected with earth leakage protective device.
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.
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.
