Abstract
The utility model relates to a static contact, arc extinguishing bars assembly modular mould shell type circuit breaker. Its characteristics have adopted semi -enclosed explosion chamber technique, according to appearance and both position relation when assembling of static contact part and arc extinguishing bars, have designed two arc -extinguish chambers that mutual mirror image docked promptly for link firmly static contact part, arc extinguishing bars and du pont's cardboard inside these two arc -extinguish chambers, and then the integration is an integral module. This design makes not only that static contact parts and arc extinguishing bars etc. Are integrated to be a module, is convenient for manage and the installation for complete set of engine, and step when having simplified the circuit breaker installation for complete set of engine can the speed of improving production. And this semi -enclosed explosion chamber is technological, can improve the pressure of arc extinguishing system, produces the air -blowing effect, has great help to the breaking capacity who improves the circuit breaker to because the arc -extinguish chamber has born the air pressure that electric arc produced when the killer switch divided disconnected great overload current, and then has avoided circuit breaker housing's destruction, the life of circuit breaker has been improved.
Description
Technical field
The utility model belongs to a kind of low-voltage circuit breaker, particularly relates to the mold cased circuit breaker of a kind of fixed contact, arc-chute fit drawing die blocking.
Background technology
Along with the development of modern industrial technology, the modularization level of low-voltage circuit breaker is had higher requirement.The parts of circuit breaker being carried out Function Classification, and then is combined into the module of difference in functionality, more different block combiner is become circuit breaker, is the developing direction of current low-voltage circuit breaker product.At contact system and the arc quenching system of current known moulded case circuit breaker, all that each parts are taken up in order of priority and are carried out assembling, the assembling of such as fixed contact, arc-chute etc. is exactly like this, like this when carrying out circuit breaker final assembly, the parts that need assemble can be a lot, and assembling process is also more loaded down with trivial details.And when the overload current that circuit breaker disjunction is larger, contact position can produce electric arc, and then produce larger pressure, very large impact can be produced to the shell of breaker of plastic casing, even can by shell pressure break, the continuation that can affect circuit breaker like this uses.
Summary of the invention
The utility model provides the mold cased circuit breaker of a kind of fixed contact, arc-chute fit drawing die blocking for solving in known technology the technical problem that exists.
The utility model for the technical scheme solving in known technology the technical problem that exists and take is: it includes the body of described circuit breaker, fixed contact parts and arc-chute, and it also includes semiclosed arc control device; Described arc control device are divided into two arc-extinguish chambers in the L-shaped left and right be connected each other; The inner upper of described right arc-extinguish chamber, has one for placing the arc extinguishing wall of described arc-chute right part, and with the akin groove of arc extinguishing wall shape of described arc-chute right part; The bottom of described right arc-extinguish chamber inside have one for place described fixed contact parts joint cover on the right side of, and the curvilinear shaped recesses similar to profile on the right side of the joint cover of described fixed contact parts; On the right side of the bottom of described right arc-extinguish chamber inside, have one for placing the support right part of described fixed contact parts, and with the akin groove of support right part profile of described fixed contact parts; One is had for placing the square aperture of Du Pont's paper in the left upper portion of described right arc-extinguish chamber inside; An oblong openings is had in the right upper portion of described right arc-extinguish chamber inside; The structure that the internal structure of described left arc-extinguish chamber is corresponding with the mutual mirror image in inside of described right arc-extinguish chamber is identical; Described semiclosed arc control device are mutually fixed into after described left and right two arc-extinguish chambers docking described arc-chute, fixed contact parts and Du Pont's paper just in time can placed wherein; Described semiclosed arc control device are fixed in described breaker body, and the moving contact of described circuit breaker can just in time extend in described semiclosed arc control device.
The advantage that the utility model has and good effect are: owing to have employed semi-enclosed arc control device technology, namely according to the profile of fixed contact parts and arc-chute and both position relationships when assembling, devise the arc-extinguish chamber of two mutual mirror image docking, for fixed contact parts, arc-chute and Du Pont's cardboard are connected in this two arc-extinguish chamber inside, and then be integrated into an integral module.This design not only makes fixed contact parts and arc-chute etc. be integrated into a module, is convenient to management and whole machine installation, simplifies step during circuit breaker whole machine installation, can improve speed of production.And this semi-enclosed arc control device technology, the pressure of arc quenching system can be improved, produce air-blowing effect, larger help is had to the breaking capacity improving circuit breaker, and due to the air pressure that electric arc when arc-extinguish chamber bears killer switch disjunction larger overload current produces, and then avoid the destruction of case for circuit breaker, improve the useful life of circuit breaker.Moreover, without regurgitating phenomenon during killer switch disjunction, protecting release, making operating characteristics more reliable.

Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Fig. 1,2,3,4,5,6, according to the profile of fixed contact parts 4 and arc-chute 3 and both status requirements when assembling, the arc control device 14 of the semiclosed arc control device module of design are divided into left arc-extinguish chamber 1 and right arc-extinguish chamber 2, structure and the profile of left arc-extinguish chamber 1 and right arc-extinguish chamber 2 are that mutual mirror image is corresponding, and monnolithic case is L-shaped.For right arc-extinguish chamber 2, the groove 8 of arc extinguishing wall 11 profile of an approximate arc-chute 3 is arranged at the top of its inside, and this groove 8 is for placing arc-chute 3; Lower left side has the curved slot 6 of the joint cover 12 of approximate fixed contact parts 4, and this groove 6 is for placing the joint cover 12 of fixed contact parts 4; Have the groove 10 of support 13 side profile of approximate fixed contact parts 4 on the right side of bottom, this groove 10 is for placing the support 13 of fixed contact parts 4; A square aperture 7 is had, for placing Du Pont's cardboard 5 in left upper portion; And an oblong openings 9 is had on right side.
