Abstract
The utility model relates to a circuit breaker convenient to install, install drive mechanism, solenoid, arc extinguishing piece, movable contact, stationary contact and terminal outgoing lines including the casing, in the casing, have a plurality of cutting in a side end face system of casing, have a plurality of fasteners that hold the cutting in the opposite side terminal surface and the one -to -one system of cutting of casing. The utility model discloses a multistage circuit breaker of cooperation installation of cutting and fastener, every single -stage circuit breaker all is equivalent to a module, can assemble into multistage circuit breakers such as 2P, 3P, 4P. It is simple quick, not hard.
Description
Technical field
The utility model belongs to field of circuit breakers, relates to the mounting structure of circuit breaker, especially a kind of circuit breaker being convenient to install.
Background technology
Circuit breaker multiple levels needs multiple single-stage circuit breaker to be cascaded by copper pipe when connecting, and needs prefabricated four holes running through copper pipe in the corner of single-stage circuit breaker, during use, inserts copper pipe, be connected and fixed by copper pipe after being spelled by multiple single-stage circuit breaker.This connected mode, installs and bothers very much, and dismounting also difficulty.Due to adjacent two single-stage circuit breakers snugly closely, so it is bad to cause circuit breaker internal components and parts to dispel the heat, generally for heat radiation, also need additionally to make louvre at the shell of circuit breaker, technics comparing is complicated.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of perfect heat-dissipating is provided and be convenient to install circuit breaker.
The technical scheme that the utility model technical solution problem adopts is:
A kind of circuit breaker being convenient to install, comprise housing, transmission mechanism, solenoid, arc quenching plate, moving contact, fixed contact and outlet terminal are installed in housing, be shaped with multiple cutting in a side end face of housing, be shaped with the fastener of multiple accommodation cutting at the opposite side end face of housing and cutting one_to_one corresponding.
And the cross sectional shape of described cutting is convex, the cross sectional shape of described fastener is C type.
And described cutting is horizontal cutting or longitudinal cutting, described fastener is horizontal fastener or longitudinal fastener.
And described cutting and fastener uniform intervals are built in the both sides of housing.
Advantage of the present utility model and good effect are:
1, the utility model installs circuit breaker multiple levels by the cooperation of cutting and fastener, and each single-stage circuit breaker is equivalent to a module, can be assembled into the circuit breaker multiple levels such as 2P, 3P, 4P.Simple and quick, not difficultly.
2, after the utility model is assembled into circuit breaker multiple levels, there is gap between two adjacent single-stage circuit breakers, be conducive to the heat radiation of Shell of circuit breaker internal component, extend the useful life of circuit breaker.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 be Fig. 1 right view;
Fig. 4 is the schematic diagram that the utility model is spliced into 2P circuit breaker;
Fig. 5 is internal structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
Be convenient to the circuit breaker installed, comprise housing 1, transmission mechanism 4 is installed in housing, solenoid 7, arc quenching plate 8, moving contact 6, fixed contact 5 and outlet terminal 9.
Innovative point of the present utility model is:
Be shaped with at a vertical uniform intervals in side end face of housing the horizontal cutting 3 that multiple cross section is convex, be shaped with at the opposite side end face of housing and cutting one_to_one corresponding the horizontal fastener 2 that multiple cross section is the cutting held of C shape.
Described cutting and fastener are not limited only to laterally on housing, also can longitudinally on housing.
During installation, first aim at two single-stage circuit breakers, then cutting is pushed in fastener and multiple single-stage circuit breaker can be assembled into circuit breaker multiple levels.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from utility model design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
