Abstract
The utility model relates to a mould shell type circuit breaker, jump knot including the casing and in locating the casing, its characterized in that: the jump detain including the basal portion and with basal portion fixed connection's linking portion, the basal portion on be equipped with the mounting groove, grow is gradually located by the tank bottom toward the notch to the width of this mounting groove, linking portion include first plate, second plate, third plate, fourth plate, the 5th plate and the 6th plate, the utility model discloses lie in: this structural design has guaranteed to jump to detain the spare part motion that can drive in the circuit breaker, and the bulk strength is stronger, has guaranteed life to offer the operation that the circuit breaker can be normal, be equipped with the mounting groove on the basal portion, grow is gradually located by the past notch of tank bottom to the width of this mounting groove, has played the effect of direction in the installation, and is easy to assemble, thereby it detains rapid the installing in the casing of ability to make to jump, has improved work efficiency.
Description
Technical field
The utility model relates to field of circuit breakers, especially a kind of mold cased circuit breaker.
Background technology
At present, existing mold cased circuit breaker comprises tripping, and tripping will drive the parts motion in breakerTime, the intensity of tripping is poor, and very easily fracture, has reduced service life, thereby has not driven in breakerParts motion, can not move breaker normally.
Utility model content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of intensity strong, protectCard service life and tripping can drive the mold cased circuit breaker of the parts motion in breaker.
The technical solution of the utility model is achieved in that a kind of mold cased circuit breaker, comprises housing and establishesTripping in housing, is characterized in that: what described tripping comprised base portion and was fixedly connected with base portion is connectedPortion, described base portion is provided with mounting groove, and the width of this mounting groove becomes greatly gradually from bottom land toward notch place, instituteThe convergence part of stating comprises the first plate, the Second Board, the 3rd plate, the 4th plate, the 5th plate and the 6thPlate, the first described plate and base portion angulation are 93 degree, described the first plate and the Second BoardAngulation is 148.5 degree, and described the Second Board and the 3rd plate angulation are 134.5 degree, instituteThe 3rd plate of stating and the junction of the 4th plate are arcwall face, and the radian of this arcwall face is 178 degree, described inThe 4th plate and the 5th plate angulation be 112 degree, the 5th described plate becomes with the 6th plateAngle be 157 degree, described the 6th plate and base portion angulation are 90 degree.
Be preferably: the ratio of the notch place width of the bottom land width of described mounting groove and mounting groove is 0.4.
By adopting technique scheme, this structural design has ensured that tripping can drive the parts in breakerMotion, bulk strength is stronger, has ensured service life, can move normally thereby offer breaker,On base portion, be provided with mounting groove, the width of this mounting groove becomes greatly gradually from bottom land toward notch place, in installation processIn played the effect of guiding, thereby tripping can be installed in housing rapidly, improved operating efficiency;And the ratio of the notch place width of the bottom land width of mounting groove and mounting groove is 0.4, has ensured the entirety of mounting grooveIntensity, has ensured service life.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below by rightIn embodiment or description of the Prior Art, the accompanying drawing of required use is briefly described, apparently, belowAccompanying drawing in description is only embodiment more of the present utility model, for those of ordinary skill in the art,Do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model detailed description of the invention structural representation;
Fig. 2 is tripping structural representation in the utility model detailed description of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodimentCase is clearly and completely described, and obviously, described embodiment is only that the utility model part is realExecute example, instead of whole embodiment. Based on the embodiment in the utility model, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to the utility modelThe scope of protection.
As shown in Fig. 1-Fig. 2, the utility model discloses a kind of mold cased circuit breaker, comprise housing A andBe located at the tripping B in housing, in the utility model specific embodiment, described tripping B comprises base portion 1And the convergence part 2 being fixedly connected with base portion, described base portion 1 is provided with mounting groove 11, this mounting groove 11Width becomes greatly gradually from bottom land toward notch place, described convergence part 2 comprise the first plate 21, the Second Board 22,The 3rd plate 23, the 4th plate 25, the 5th plate 26 and the 6th plate 27, described the first plate 21 withBase portion A angulation is 93 degree, and the first described plate 21 with the Second Board 22 angulations is148.5 degree, described the Second Board 22 and the 3rd plate 23 angulations are 134.5 degree, described theThe junction of three plates 23 and the 4th plate 25 is arcwall face 24, and the radian of this arcwall face 24 is 178 degree,The 4th described plate 25 and the 5th plate 26 angulations are 112 degree, described the 5th plate 26 withThe 6th plate 27 angulations are 157 degree, and the 6th described plate 27 with base portion A angulation is90 degree.
In the utility model specific embodiment, the bottom land width of described mounting groove 11 and the notch of mounting grooveThe ratio of place's width is 0.4.
By adopting technique scheme, this structural design has ensured that tripping can drive the parts in breakerMotion, bulk strength is stronger, has ensured service life, can move normally thereby offer breaker,On base portion, be provided with mounting groove, the width of this mounting groove becomes greatly gradually from bottom land toward notch place, in installation processIn played the effect of guiding, thereby tripping can be installed in housing rapidly, convenient installation, has improvedOperating efficiency; And the ratio of the notch place width of the bottom land width of mounting groove and mounting groove is 0.4, has ensured peaceThe bulk strength of tankage, has ensured service life.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., allWithin should being included in protection domain of the present utility model.
