Abstract
The utility model relates to an adjustable moulded case circuit breaker which mainly solves the problem that the distance of double metal sheets of the existing circuit breaker is nonadjustable and can only be adaptive to the fixed current. The adjustable moulded case circuit breaker is characterized in that an ejector block is fixed on a traction rod, a transversely inclined surface is formed at the position where the ejector block corresponds to a screw, and an operation mechanism connected with the traction rod is arranged at the outer side of a shell and drives the traction rod to transversely move. As the distance between the double metal sheets and a tripping mechanism is adjustable, the distance between the double metal sheets and the tripping mechanism can be adjusted according to different bending levels of the double metal sheets caused by different current so as to adapt to the different bending levels, so that the usage range of the circuit breaker can be extended to a certain current range.
Description
Technical field
The utility model relates to a kind of circuit breaker, refers in particular to adjustable breaker of plastic casing.
Background technology
The thermal overload protection circuit breaker adopts a bimetal leaf of connecting with circuit; the heat that electric current produces between overcharge period can make bimetal leaf flexural deformation; thereby order about the tripping mechanism action and make circuit breaker trip; safety with protective circuit and equipment; the big more generation heat of electric current is many more, and the bimetal leaf degree of crook is big more.
At present; the bimetal leaf and the distance between the tripping mechanism of circuit breaker are non-adjustable; can only adapt to fixing electric current; the heat that electric current produces makes the bimetal leaf bending order about the tripping mechanism action, and is still, unfixed to some electric currents; just can not be suitable for; promptly can not regulate distance between bimetal leaf and the tripping mechanism according to the size of electric current, to offer the space of bimetal leaf bending, this makes the scope of application of circuit breaker overload protection be subjected to certain restriction.
Summary of the invention
For the shortcoming and deficiency that overcome background technology, the utility model provides a kind of adjustable breaker of plastic casing, has solved the problem that existing circuit breaker bimetal leaf position can only adapt to fixed current.
The technical solution of the utility model is: a kind of adjustable breaker of plastic casing, comprise housing, be provided with bimetal leaf, draw bar, connecting lever and tripping mechanism in the described housing, described bimetal leaf front end is provided with screw, described connecting lever is located on the draw bar and with tripping mechanism and is matched, it is characterized in that: be fixed with jacking block on the described draw bar, described jacking block and screw corresponding section are the inclined-plane along lateral inclination, described hull outside is provided with the operating mechanism that is connected with draw bar, and described operating mechanism drives draw bar and laterally moves.
Further, described operating mechanism is a knob, is fixed with projection on the described draw bar, and described projection is provided with chute, and described knob is provided with the eccentric rod that matches with chute.
Further, described bimetal leaf is three, and corresponding draw bar is provided with three jacking blocks that match with described bimetal leaf.
The utlity model has following beneficial effect: because the distance between bimetal leaf and the tripping mechanism is adjustable, thereby can be according to the size of electric current, the degree of crook difference of the bimetal leaf that brings, and the distance between adjusting bimetal leaf and the jacking block, to adapt to different degree of crook, this makes the scope of application of this circuit breaker enlarge, and can be applicable to certain current range.
Description of drawings
Fig. 1 is a partial sectional view of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Among the figure, housing 1, bimetal leaf 2, draw bar 3, connecting lever 4, tripping mechanism 5, screw 6, jacking block 7, knob 8, projection 9, chute 10, eccentric rod 11.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
Shown in figure, this adjustable breaker of plastic casing, comprise housing 1, be provided with bimetal leaf 2, draw bar 3, connecting lever 4 and tripping mechanism 5 in the described housing 1, described bimetal leaf 2 front ends are provided with screw 6, described connecting lever 4 is located on the draw bar 3 and with tripping mechanism 5 and is matched, be fixed with jacking block 7 on the described draw bar 3, described jacking block 7 and screw 6 corresponding sections are the inclined-plane along lateral inclination, described housing 1 outside is provided with the operating mechanism that is connected with draw bar 3, and described operating mechanism drives draw bar 3 and laterally moves.In the utility model, screw 6 contact-making surfaces on described jacking block 7 and the bimetal leaf 2 are the inclined-plane, so to drive jacking block 7 horizontal when mobile when draw bar 3, distance between the inclined-plane of jacking block 7 and the bimetal leaf 2 will change, according to such scheme, because the distance between bimetal leaf 2 and the tripping mechanism 5 is adjustable, thereby can be according to the size of electric current, the degree of crook difference of the bimetal leaf 2 that brings, and the distance between adjusting bimetal leaf 2 and the jacking block 7, to adapt to different degree of crook, this makes the scope of application of this circuit breaker enlarge, and can be applicable to certain current range.
In the utility model, described operating mechanism is a knob 8, is fixed with projection 9 on the described draw bar 3, and described projection 9 is provided with chute 10, and described knob 8 is provided with the eccentric rod 11 that matches with chute 10.By turning knob 8, make that the eccentric rod on the knob 8 matches with chute, laterally move thereby drive draw bar 3, can regulate the distance between jacking block 7 and the bimetal leaf 2 as required, realize the purpose of adjusting, accuracy height, stable strong.
In the utility model, described bimetal leaf 2 is three, and corresponding draw bar 3 is provided with three jacking blocks 7 that match with described bimetal leaf 2.Because this circuit breaker is a composite type; three bimetal leafs 2 are arranged; in order to make three bimetal leafs 2 when being subjected to thermal overload; all can make tripping mechanism 5 move; the corresponding jacking block 7 that matches with bimetal leaf 2 of on draw bar 3, fixing; as long as wherein any one bimetal leaf 2 thermal overload produces crooked; just can impel jacking block 7 to drive draw bar 3 rotations makes the connecting lever 4 on the draw bar 3 move; can make tripping mechanism 5 move and the purpose of realization protective circuit fast and effectively, safe, stable strong.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
