Abstract
The utility model discloses a residual-current circuit breaker handle. The residual-current circuit breaker handle is characterized in that a wrench portion is sleeved with a reinforcing sleeve; two side surfaces of the wrench portion are respectively provided with a guide groove; each guide groove is composed of two protruding ribs which are arranged at intervals at a corresponding side surface of the wrench portion; a boss is arranged between the two protruding ribs; and one end of the boss, which faces a bearing portion, is chamfered; clamping grooves sleeve the reinforcing sleeve; the reinforcing sleeve is arranged in the guide grooves in a sheathed manner; and the bosses are buckled with the clamping grooves. According to the residual-current circuit breaker handle of the utility model, the bosses in the guide grooves are in clamping fit with the clamping grooves, such that the reinforcing sleeve can be closely attached to the wrench portion. Thus, the residual-current circuit breaker handle is advantageous in convenient assembly, enhanced strength and easiness in processing.
Description
Technical field
The utility model relates to low voltage electrical apparatus technology field, and more particularly, it relates to a kind of residual current circuit breaker handle.
Background technology
Aftercurrent protection circuit breaker with automatic reclosing belongs to a kind of of residual current circuit breaker, is current use a kind of circuit breaker very widely.This circuit breaker is when work, and motor drive mechanism drives the action of residual current circuit breaker handle, and then handle passes to circuit breaker operation mechanism by actuating force, thereby realizes the separating brake/combined floodgate of circuit breaker.Therefore, this residual current circuit breaker handle need to have the active force that higher mechanical strength is born motor drive mechanism.In prior art, residual current circuit breaker handle is plastic material, use for a long time handle can cannot bear the active force of motor drive mechanism, handle there will be fracture, has potential safety hazard, reduces circuit breaker useful life.
At present; (Chinese patent that application number is 201320370061.8 discloses a kind of residual current circuit breaker handle) on market; the protective sleeve that it comprises handle body and is sleeved on the spanner outside of described handle body; it is characterized in that: two sides of described spanner respectively form at least one boss; the side plate of described protective sleeve forms through hole on the position corresponding to described boss; the shape of described boss and described through hole adapts and passes described through hole, and described spanner and described protective sleeve fit tightly.Although this structure has been strengthened handle strength to a certain extent; but handle body and protective sleeve assembling are to have coordinated with through hole by boss; this need to need high requirement to boss and the size of through hole own and position dimension, is difficult to processing, is also not easy to assembling simultaneously.
Utility model content
The deficiency existing for prior art, the residual current circuit breaker handle that the purpose of this utility model is to provide a kind of and is easy to processing, is convenient to assembling, intensity is high.
For achieving the above object, the utility model provides following technical scheme: a kind of residual current circuit breaker handle, comprise handle body, described handle body comprises spanner portion and the carrier being wholely set, described spanner portion is arranged with reinforcing sleeve, the two sides of described spanner portion are equipped with gathering sill, described gathering sill consists of spaced two convex tendons in spanner portion side, between two convex tendons, be provided with boss, described boss is provided with chamfering towards one end of carrier, described reinforcing sleeve is provided with draw-in groove, and described reinforcing sleeve is placed in gathering sill, and described boss and described draw-in groove are interlocked.
By adopting technique scheme, the two sides of described spanner portion are equipped with gathering sill, described gathering sill consists of two convex tendons of spanner portion side, and reinforcing sleeve enters in gathering sill by the chamfering on convex tendon, and convex tendon is placed in reinforcing sleeve both sides, reinforcing sleeve is under the guide effect of two convex tendons, move down, boss and draw-in groove in gathering sill are fastened, reinforcing sleeve and spanner portion are fitted tightly, be convenient to assembling, also strengthen the intensity of spanner portion simultaneously; Convex tendon and boss and spanner portion are all one-body molded injection mouldings, do not need additional processing, and convex tendon and boss size do not need especially precisely can make reinforcing sleeve firmly yet and fit tightly in spanner portion, are convenient to processing.
The utility model is further set to: described boss and the height of convex tendon are identical with the thickness of reinforcing sleeve.After described reinforcing sleeve and spanner portion fit tightly, the upper surface of described boss and convex tendon is concordant with reinforcing sleeve surface, described boss can directly not contact with motor drive mechanism with convex tendon, has reduced the resistance of operation, can effectively avoid the damage of motor drive mechanism to spanner portion.
The utility model is further set to: one end that two convex tendons are relative with carrier is equipped with chamfering, and the chamfering on two convex tendons arranges in opposite directions.Two convex tendons arrange chamfering and are convenient to reinforcing sleeve and enter in gathering sill.
By adopting technique scheme, the two sides of described spanner portion are equipped with gathering sill, described gathering sill consists of two convex tendons of spanner portion side, and reinforcing sleeve enters in gathering sill by the chamfering on convex tendon, and convex tendon is placed in reinforcing sleeve both sides, reinforcing sleeve is under the guide effect of two convex tendons, move down, boss and draw-in groove in gathering sill are fastened, reinforcing sleeve and spanner portion are fitted tightly, be convenient to assembling, also strengthen the intensity of spanner portion simultaneously; Convex tendon and boss and spanner portion are all one-body molded injection mouldings, do not need additional processing, and convex tendon and boss size do not need especially precisely can make reinforcing sleeve firmly yet and fit tightly in spanner portion, are convenient to processing.
