Abstract
The utility model discloses a novel residual-current circuit breaker including a shell and a press button. The shell is composed of a bottom shell, a middle cover and an upper cover. The middle cover is covered with the upper cover and the bottom shell respectively, so that an arc extinguishing chamber is formed. The arc extinguishing chamber is provided with an arc extinguishing shade, an N movable contact and an L movable contact respectively. The press button is stuck on a movable button spring. One end of the movable button spring is connected with a lead and is pressed on a blocking board above a steel magnet. The other end of the movable button spring is contacted with a static button sheet when the movable button spring is closed. An arc-distinguished shade is arranged below N static contact on the bottom shell of the novel residual-current circuit breaker. The arc-distinguishing shade is pressed against an arc-striking sheet. An end of the arc-striking sheet is connected with a conductor and is also connected with an end of the N static contact. The conductor is not connected to a wire outlet frame, but extended outside the shell along a bottom shell groove after turning and connected to the lead in parallel. The shell is also inside provided with a voltage protection device and a current protection device. The novel residual-current circuit breaker provided by the utility model has beneficial effects that the novel residual-current circuit breaker is reasonable in design, low in manufacturing cost, comparatively low in space occupancy, convenient and safe to use and good in universality.
Description
Technical field
This practicality relates to the electric prospection technical field, relates in particular to a kind of novel residual current circuit breaker.
Background technology
At present, the circuit breaker that people use in market and life does not possess multi-functional, and have in order to realize the multi-functional volume that but reduces arc-control device, more very be simply to save arc-extinguish chamber, such circuit breaker greatly reduces it and uses safety.In order to realize described function, traditional product only could be realized corresponding function adding under the situation of large volume, and the result that such mode is brought is that product is oversize, influences attractive in appearancely, more influences versatility etc.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of novel residual current circuit breaker.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of novel residual current circuit breaker; comprise housing and button; housing is by end shell; middle cover; loam cake constitutes; middle cover constitutes arc control device with loam cake and end casing cover respectively together; arc control device are respectively equipped with arc-extinguish chamber; N moving contact and L moving contact; button snap is on moving button spring; moving one of button spring connects lead and is pressed on the plate washer above the magnet steel; the other end touched quiet button piece when moving button spring was closed; N fixed contact below at the bottom of the circuit breaker on the shell is provided with arc-extinguish chamber; arc-extinguish chamber withstands on the striking sheet; one of striking sheet is connected with conductor; be connected with N fixed contact lead one end, conductor is not received out on the wire frame but is turned back to be stretched over along end shell groove and is attempted by outside the shell on the lead, also is provided with voltage protection and current protective device in the housing yet.
Described residual current circuit breaker cover top portion is provided with indication window.
The beneficial effects of the utility model: reasonable in design, the low cost of manufacture of this utility model; Occupation space is less, uses more convenient; Use saferly, versatility is better.
