Description

The support that is used for electromagnetic release mechanism
Technical field
The utility model belongs to breaker technical field, is specifically related to a kind of support for electromagnetic release mechanism.
Background technology
Circuit breaker is to use extremely wide product as the overload in low-voltage distribution system and the motor protection loop, short circuit, under voltage protection electrical equipment.The structure of circuit breaker generally is comprised of contact system, arc-control device, operating mechanism, trip gear, plastic casing and optional accessory.Contact system comprises and is connected on the dynamic/static contact that arranges in pairs in the circuit, and circuit transships, during the fault such as short circuit, under voltage, opens at the appointed time dynamic/static contact when the circuit breaker place, line disconnection, and protection circuit and power-supply device are not damaged; The electric arc that arc-control device is used for extinguishing dynamic/static contact to be produced when opening; Trip gear comprises thermal release device, electromagnetic release mechanism, undervoltage tripping mechanism; When circuit was short-circuited, short circuit current flow through trip gear, and the action of magnetic tripping mechanism is threaded off operating mechanism, and circuit breaker trip is realized the protection to circuit breaker place circuit and load.
The magnetic tripping mechanism comprises armature, yoke, spring, support, existing armature is usually with the both sides bending, offer symmetrically through hole at two bending parts, the top is provided with upwardly extending brake bar, support both sides symmetry is offered through hole, the support both sides are simultaneously with armature two bending part envelopes, and the through hole on armature two bending parts is all corresponding with through hole on the support both sides, join armature is compatible with support by the through hole offered on the through hole offered on the support both sides and the armature bending part respectively thereby be convenient to bolster, so that armature can be bearing on the support rotatably around bolster.In the electromagnetic release mechanism of this structure, the armature both sides need bending, also need offer through hole on it, are not easy to the processes of armature; Because the through hole on the support both sides will correspondingly with the through hole on armature two bending parts pass to hold bolster, be unfavorable for saving part, both assemblings are loaded down with trivial details, time-consuming, the whole electromagnetic release mechanism of this structural requirement will be finished the assembling of armature and support before the pedestal of packing into simultaneously, otherwise can bring obstruction to the installation of other devices such as bimetallic element, operating mechanism etc.; When circuit is short-circuited, armature rotates, its brake bar hits the draw bar in the pneumatic operating mechanism, and armature position is corresponding with draw bar, namely, stipulated the position of electromagnetic release mechanism in whole circuit breaker, so the position of armature, shape, size can exert an influence to shape, size and the mounting means of circuit breaker miscellaneous part, thus, the volume of whole circuit breaker be will have influence on, the densification assembling of circuit breaker inner member and the miniaturization of circuit breaker itself are difficult to realize.
Summary of the invention
The support that is used for electromagnetic release mechanism that the purpose of this utility model provides the comparatively reasonable compactness of a kind of structure and has adjustability.
The technical scheme that realizes the utility model purpose is: a kind of support for electromagnetic release mechanism, comprise two side and the connecting wall that is connected the two side, and be equipped with a pivot groove on each sidewall; Described support is provided with spacing breach at its at least one sidewall; The opening upwards of described spacing breach; Positive stop lug boss on the described armature is positioned at the pivot boss below; Described support connecting wall is provided with hanging hole, and at least one side of described hanging hole is wave, and described support forms a plurality of hooking stopper slots at this wave place.
In the such scheme, the basic configuration of described spacing breach is rectangle or convex shape.
The utlity model has positive effect: in (1) the utility model, described support is provided with spacing breach at its at least one sidewall; Described armature also is provided with the positive stop lug boss that is arranged in this spacing breach at a lateral edges place adjacent with described spacing breach; Described armature is along in its pivot boss rotation process, and its positive stop lug boss can move back and forth in corresponding spacing breach.The utility model is when assembling, only need make spacing lug on the armature be shelved on to reach in the spacing breach armature rotational angle is carried out spacing purpose, assembling and unloading process are also comparatively simple, adopt this structure needn't after being assemblied in armature on the support, stamp out again the operation of positive stop lug boss at the sidewall of support, manufacturing process is simplified to a certain extent, has also guaranteed the reliability of its action of threading off.
(2) in the utility model, the basic configuration of described spacing breach preferably adopts convex shape, this spacing breach can effectively prevent described armature in vertical direction because vibration, make the slippage from pivot groove and spacing breach of its integral body cause this electromagnetic release mechanism to fall apart, make it in conjunction with more solid and reliable, be difficult for breaking down.
(3) in the utility model, at least one side of described hanging hole is wave, described support forms a plurality of hooking stopper slots at this wave place, thereby has adjustability, this kind structure so that external back-moving spring in use, can be by back-moving spring one end be hooked in the different hooking stopper slots, thus regulate the reseting elasticity of back-moving spring, thereby so that identical product can be used in the breaker of plastic casing of different model.
