Embodiment
Now in conjunction with the accompanying drawings the utility model execution mode is further described:
As shown in the figure as can be known, the embodiment of a kind of residual current circuit breaker of the utility model, include Electrical leakage unit 1 and breaker unit 2, breaker unit 1 can be for a plurality of, Electrical leakage unit 2 equally can be for a plurality of, each Electrical leakage unit 2 and breaker unit 1 be by rivet, and illustrated embodiment adopts four utmost points, four utmost point Electrical leakage modes that open circuit; Illustrated Electrical leakage unit 2 include housing 21 and be arranged in the housing 21 the release assembly and into and out of wire terminal, correspond to out wire terminal 22 on the described housing 21 and be provided with connection jaws 213, between adjacent connection jaws 213, be provided with flash barrier 211; Described breaker unit 1 includes housing 11 and is arranged on moving in the housing 11, fixed contact and lead-in line joint and go out wire terminal 12, describedly go out wire terminal 12 and include screw 121, quiet wire frame 122 and moving wire frame 123, the corresponding line outlet 113 that is provided with on housing 11, screw 111 and the breach 112 that is positioned at the line outlet top, line outlet 113 1 sides of Shell of circuit breaker 11 also capping protective cover 3 is arranged, described protective cover 3 is provided with clamping sheet 31 (in the diagram owing to adopt the four-pole circuit breaker formula, so four clamping sheets 31 are arranged, if a utmost point is a slice clamping sheet 31 then, other number is analogized), this clamping sheet 31 penetrates and is arranged in from breach 112 between the upper wall surface of the head upside of screw 121 and breach 112.Owing to adopt the mode of clamping sheet 31 clampings, therefore when dismounting protective cover 3, do not need to twist screw, pull out protective cover 3 and just can unload as long as scratch with hand, more convenient to operate, in addition, because clamping sheet 31 also is covered in the upside of screw 121, utilizing clamping sheet 31 to be about to screw 121 separates with the external world, therefore do not need to establish in addition the screw sealing cover, so this protective cover has just played the protective cover in the background technology and the double action of screw sealing cover, install very convenient reliably.
In order to guarantee the installation connection reliability of clamping sheet 31, present embodiment also is provided with eave tile 311 at the upside of described clamping sheet 31, and these eave tile 311 trips are in the inwall of the upper wall of breach 112.This eave tile 311 cooperates with the trip of the inwall of the upper wall of Shell of circuit breaker breach 112 will make protective cover 3 can pull out when pulling out with hand is stingy, be not difficult for dropping out when pulling out and do not scratch, thereby make the installation reliability of protective cover 3 be guaranteed, the convenience when not influencing dismounting again.Present embodiment can certainly extend shell fragment downwards in the both sides of clamping sheet, the head that utilizes the elasticity of this two shell fragment to encase screw drops to prevent that the protective cover pine from unloading, perhaps even, be arranged on the both sides of clamping sheet at eave tile, and on the two side of breach, establish draw-in groove, utilize the eave tile of both sides to cooperate to prevent that the protective cover pine from unloading drops with the draw-in groove clamping; The utility model is more preferably used the mode of illustrated embodiment, and is because with respect to the back dual mode, convenient in the obvious processing and manufacturing of by way of example as shown in the figure.
In the present embodiment, have better elastic in order to guarantee eave tile 311, the both sides of eave tile 311 and rear side are made as dead slot 312, and this dead slot 312 communicates in the front 37 of protective cover 3.
In the illustrated embodiment, also be provided with on protective cover 3 and line outlet 113 corresponding louvres 32, louvre 32 adopts the row arrangement settings usually, louvre 32 is set helps distributing of heat that the joint place produces, thereby guarantee the normal operation of circuit breaker.
In the present embodiment, described protective cover 3 extends to the lateral surface of Electrical leakage 2, is provided with square hole 33 at protective cover 3 with respect to the connection jaws that goes out wire terminal 22 213 places of the housing 21 of Electrical leakage 2.The lateral surface (being that protective cover aligns with the lateral surface of Electrical leakage) that protective cover 3 is extended to Electrical leakage 2 has covered in flash barrier 211, make residual current circuit breaker have good whole performance attractive in appearance, be used for passing through of load side wire by square hole 33 in addition, make user's finger to put between flash barrier and to contact, guaranteed the safety of using by square hole with joint.
In the present embodiment, the upper and lower both sides of described square hole 33 also are provided with reinforcement 34 long to convex and that align with the edge 36 of protective cover 3, this reinforcement 34 is sheathed in the space 212 that forms between the described adjacent flash barrier 211, by as show and be provided with the intensity that is beneficial to the Electrical leakage side that guarantees protective cover, and further improve the arc performance.
Because the length of protective cover 3 obtains extending, therefore in order further to guarantee the installation fastness of protective cover 3, all be provided with draw-in groove 213 between the upside of adjacent flash barrier 211 and between the downside, the corresponding trip 35 that cooperates with draw-in groove 214 clampings that is provided with on protective cover 3.
Though more than described embodiment of the present utility model, but the those of skill in the art in the present technique field are to be understood that, these only illustrate, and can make numerous variations or modification to these execution modes, and not deviate from principle of the present utility model and essence.Protection range of the present utility model is only limited by appended claims.
