Description
Technical field
The utility model is specifically related to a kind of residual current circuit breaker.
Background technology
At present, residual current circuit breaker is applicable to the various places such as industry, business, high level and residential houses.When the person gets an electric shock or electrical network Leakage Current exceedes setting; this design prod can within the extremely short time rapid disengagement failure power supply; the protection person and the safety of power consumption equipment, simultaneously can the overload of protection circuit and short circuit, also can be used as the use of the infrequently operation transformation of circuit.There is the defect that structural design is unreasonable, dust-proof effect is poor in existing residual current circuit breaker, thus causes the unstable properties of this leakage, breaking, useful life short.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides a kind of long service life, good dustproof effect, residual current circuit breaker stable and reliable for performance.
For achieving the above object, the utility model adopts a kind of residual current circuit breaker, comprise base, upper cover, be installed on the clamp in the installation cavity on base lower surface, handle, operating mechanism, leakage tripping device, the two ends of the upper surface of described upper cover are respectively arranged with a baffle plate, described each baffle plate is corresponding respectively to be blocked on the screw at upper cover two ends, the two ends of described baffle plate are respectively arranged with a clamp, the clamp place covered on described described in correspondence is provided with suitable hole clipping, described clamp is installed on formation baffle plate in hole clipping and is connected with the buckle of upper cover, cover on described and be provided with a lock hole, on described baffle plate, corresponding lock hole place is provided with a suitable through hole.
The beneficial effect of said structure is: this residual current circuit breaker by having blocked a baffle plate on the screw of upper cover, thus avoid dust from screw, drop into the inside of residual current circuit breaker, improve dust-proof effect, and the mode that baffle plate and upper cover adopt buckle to be connected connects, thus be convenient to dismounting and the installation of baffle plate, by baffle plate and on cover and be respectively arranged with through hole and lock hole, user only with lockset or iron wire successively through through hole, lock hole, can need cover locked for baffle plate upper.
Especially, the both sides of described clamp are respectively arranged with a card base, side in the middle part of described card base is provided with a spacing preiection, on the madial wall of described installation cavity, corresponding spacing preiection place is provided with the draw-in groove in odontoid, described spacing preiection is installed on formation clamp in draw-in groove and is connected with the buckle of base, and the lower end bending of card base is configured with a resilience pin in hook-shaped.By being provided with resilience pin on the card base of clamp, enhance the elasticity of card base, avoid card base because of the extruding force that is subject to excessive and damage, thus extend the useful life of this clamp.
