The high-reliability adjustable current circuit breaker comprises an adjusting screw, contacts, a metal sheet, a shell, a press button, a spring, a gasket and electrified bodies, wherein one end of the adjusting screw penetrates through the shell; the press button is sleeved at the other end of the adjusting screw; the spring is arranged between the press button and the gasket; the press button, the spring and the gasket are sequentially connected with one another; the gasket is sleeved on the adjusting screw in an impermanent connection mode; the metal sheet is fixed to the adjusting screw; the contacts are arranged at two ends of the metal sheet respectively; the electrified bodies are arranged on the shell and opposite to the contacts; the circuit breaker is convenient to switch on/off by controlling the metal sheet by the press button; rated current is adjusted by rotating the adjusting screw; and the high-reliability adjustable current circuit breaker is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of highly reliable adjustable electric streaming circuit breaker.
Background technology
When circuit breaks down or is unusual; Being accompanied by electric current constantly raises; And the electric current that raises might damage some important devices or valuable device in the circuit, also might burn circuit even cause fire, so can cause the massive losses of life and property.Breaker structure on the market is complicated, and cost is high, when fault has taken place circuit, after circuit breaker cuts off circuit, in the maintenance process that circuit needs, if will there be sizable potential safety hazard in the automatic energized of circuit breaker.
The utility model content
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, to provide a kind of simple in structure, and cost is low, can regulate current limit, and can realize manual control switch's highly reliable adjustable electric streaming circuit breaker.
Technical scheme: in order to realize above purpose, the described a kind of highly reliable adjustable electric streaming circuit breaker of the utility model, it comprises adjustment screw, contact; Sheet metal, housing, button, spring; Pad and energising body, an end of described adjustment screw is arranged on the housing, and button is sheathed on the other end of adjustment screw, and the middle of button and pad is provided with spring; Described button, spring links to each other with pad successively, and described pad is sheathed on the adjustment screw with the on-fixed ways of connecting; Institute's sheet metal be fixedly arranged on the adjustment screw on, the two ends of sheet metal are respectively equipped with the contact, the energising body be located at the contact relative position housing on.
Described adjustment screw, sheet metal, button, spring and pad are positioned on the same axis.
Beneficial effect: a kind of highly reliable adjustable electric streaming circuit breaker that the utility model provides, can realize the Kai Heguan of circuit breaker through the button control sheet metal easily, through turn adjustment screw adjustment rated current, and simple in structure, cost is low.
Description of drawings
Fig. 1 is the full sectional view of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Be illustrated in figure 1 as the described a kind of highly reliable adjustable electric streaming circuit breaker of the utility model, it comprises adjustment screw 1, contact 2, sheet metal 3; Housing 4, button 5, spring 6, pad 7 and energising body 8; One end of described adjustment screw 1 is arranged on the housing 4, and button 5 is sheathed on the other end of adjustment screw 1, and the middle of button 5 and pad 7 is provided with spring 6; Described button 5, spring 6 links to each other with pad 7 successively, and described pad 7 is sheathed on the adjustment screw 1 with the on-fixed ways of connecting; Described sheet metal 3 is fixedly arranged on the adjustment screw 1, and the two ends of sheet metal 3 are respectively equipped with contact 2, and energising body 8 is located on the housing 4 with contact 2 relative positions.
Described adjustment screw 1, sheet metal 3, button 5, spring 6 is positioned on the same axis with pad 7.
When being surpassed setting by the electric current in the protective circuit; Sheet metal 3 is heated and is bent upwards; Opened with the energising body in 8 minutes the contact 2 at sheet metal 3 two ends that are, has realized the cut-out circuit, can not resile voluntarily after sheet metal 3 coolings that are bent upwards; If need reclose circuit, must press the button 5 and could make sheet metal 3 reset.When needs adjustment rated current, the amount of deflection that turn adjustment screw 1 changes sheet metal 3 realizes the adjustment rated current.
A kind of highly reliable adjustable electric streaming circuit breaker that the utility model provides can be realized the Kai Heguan of circuit breaker easily through the button control sheet metal, through turn adjustment screw adjustment rated current, and simple in structure, cost is low.
Above-mentioned embodiment only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection range of the utility model with this.All equivalents or modifications of being made according to the utility model spirit all should be encompassed within the protection range of the utility model.
