The breaker body includes a breaker switch, a housing which includes a housing body and a housing cover plate is arranged outside the breaker body, the breaker body is arranged in the housing body and detachably connected with the housing body, one end of the housing cover plate is hinged to the housing body, the other end of the housing cover plate is buckled with the housing body, the housing cover plate is provided with radiating grooves, and the external surface of the breaker body is provided with a vibration alarm. The low-voltage circuit breaker provided by the utility model is rainproof and antitheft, has a good heat radiation performance and is long in service life.
Description
Technical field
The utility model relates to breaker technical field, particularly relates to a kind of low-voltage circuit breaker.
Background technology
Low-voltage circuit breaker is that one not only can be connected and disjunction normal duty electric current and overload electric current, can also connect the device for switching with disjunction short circuit current.Low-voltage circuit breaker except rising control action, also has certain defencive function in circuit, as overload, short circuit, under-voltage and earth leakage protective etc.
Existing low-voltage circuit breaker is much directly contained in open air, be easy to rainy day make moist, there is afterwards people to improve circuit breaker, at breaker body, one outer cover is set outward, rainwater can not be entered, but this structure but can not be dispelled the heat under high light, greatly reduced the useful life of low-voltage circuit breaker; And low-voltage circuit breaker function singleness, only there is the function of power on/off.
Utility model content
The purpose of this utility model is to overcome the deficiency existing in background technology, and the purpose of this utility model is the low-voltage circuit breaker that proposes a kind of rainproof, antitheft, perfect heat-dissipating and long service life.
For achieving the above object, the utility model adopts following scheme:
A kind of low-voltage circuit breaker, comprise breaker body, described breaker body front end face is provided with killer switch, described breaker body outside is provided with outer cover, described outer cover comprises outer cover body and outer cover cover plate, and breaker body is arranged on the inside of outer cover body, described breaker body and outer cover body removably connect, described outer cover cover plate one end and outer cover body are hinged, the outer cover cover plate other end is connected with outer cover body buckle, described outer cover cover plate is provided with radiating groove, described breaker body outer surface is provided with a vibrations siren, described radiating groove tilts, described outer cover cover plate is transparent housing, described outer cover cover plate one end is provided with dop, described outer cover body one end is provided with draw-in groove, described dop is connected with draw-in groove screens.
In above-mentioned a kind of low-voltage circuit breaker, described dop is that elastic material forms.
The beneficial effects of the utility model are: the utility model is by the waterproof outer cover being provided with in breaker body outside, can reduce circuit breaker makes moist, and described outer cover cover plate is provided with radiating groove, can efficiently radiates heat or make the in the situation that of sky heat circuit breaker self-heating, can also keep circuit breaker inner ventilation, thereby increase the useful life of low-voltage circuit breaker; And screens connect can effectively lock outer cover cover plate, in the time that stranger opens outer cover cover plate by force, the intrinsic vibrations siren of outer cover can produce warning, thereby can not be stolen by protective circuit breaker.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
With reference to figure 1 and Fig. 2, a kind of low-voltage circuit breaker, comprise breaker body 1, described breaker body 1 front end face is provided with killer switch 2, described breaker body 1 outside is provided with outer cover, described outer cover comprises outer cover body 3 and outer cover cover plate 4, and breaker body 1 is arranged on the inside of outer cover body 3, described breaker body and outer cover body removably connect, described outer cover cover plate 4 one end and outer cover body 3 are hinged, (articulated manner belongs to prior art, coming so do not illustrate in this enforcement power and mark out in Figure of description) outer cover cover plate 4 other ends are connected with outer cover body 3 buckles, described outer cover cover plate 4 is provided with radiating groove 41, described breaker body 1 outer surface is provided with a vibrations siren 5.
The waterproof outer cover being provided with by breaker body described above 1 outside, can reduce circuit breaker makes moist, and described outer cover cover plate 4 is provided with radiating groove 41, can efficiently radiates heat or make the in the situation that of sky heat circuit breaker self-heating, can also keep circuit breaker inner ventilation, thereby increase the useful life of low-voltage circuit breaker; And screens connects and can effectively lock outer cover cover plate 4, in the time that stranger opens outer cover cover plate 4 by force, vibrations siren in outer cover body 35 can produce and report to the police, thereby can not be stolen by protective circuit breaker.
In above-mentioned a kind of low-voltage circuit breaker, described radiating groove 41 is obliquely installed, and both can dispel the heat, and can prevent that again rainwater from flowing to, and radiating groove 41 is set in distance, and radiating effect is more even like this.
In above-mentioned a kind of low-voltage circuit breaker, described outer cover cover plate 4 is transparent housing, the situation in observable circuit breaker.
In above-mentioned a kind of low-voltage circuit breaker, described outer cover cover plate 4 one end are provided with dop 42, described outer cover body 3 one end are provided with draw-in groove 31, described dop 42 is connected with draw-in groove 31 screens, and described dop 42 is elastic material formation, this snap fit is not only simple in structure, and can effectively reach lock function.
The foregoing is only preferred embodiment of the present utility model, not taking the present embodiment as restriction, all any amendments of making within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection range of the present utility model.
