Abstract
The utility model discloses a bracket for an electromagnetic tripping mechanism. The bracket comprises two side walls and a connection wall connecting the two side walls, wherein each side wall is provided with a pivoting groove; at least one side wall of the bracket is provided with a limiting baffle; and the limiting baffle is a portion of the plate body, away from the connection wall, of a corresponding side wall and is formed by bending and extending toward the direction close to the other side wall. The structure has the advantages of being simple in processing and low in cost. In addition, the structure can restrict an external armature to rotate between an external magnetic yoke and the limiting baffle when being used in the electromagnetic tripping mechanism so that the overall structure is more simplified and armature limiting is more reliable.
Description
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 purpose of this utility model provides the electromagnetic release mechanism that a kind of structure is more simplified, limiting position of armature is used for circuit breaker more reliably.
The technical scheme that realizes the utility model purpose is: a kind of support for electromagnetic release mechanism, and described support comprises two side and the connecting wall that is connected the two side, is equipped with a pivot groove on each sidewall; Described support is provided with postive stop baffle at its at least one sidewall, described each postive stop baffle be on the corresponding sidewall away from the part plate body of connecting wall, towards near the direction bending of another sidewall and extend form.
In the such scheme, described postive stop baffle is positioned at pivot groove below.
The utlity model has positive effect: in (1) the utility model, described support is provided with postive stop baffle at its at least one sidewall, each postive stop baffle be on the corresponding sidewall away from the part plate body of connecting wall, towards near the direction bending of another sidewall and extend form.It is easy that this structure has processing, lower-cost advantage, in addition, this structure can be when being used for electromagnetic release mechanism, external armature is limited between external yoke and the described postive stop baffle rotates, so that overall structure more simplifies, spacing more reliable to armature.
