Abstract

The present invention relates to a kind of breaker of plastic casing, refer to especially and utilize bimetal leaf to realize the hinge-type draw bar circuit breaker protected circuit and apparatus overload.The present invention adopts following technical scheme: a kind of breaker of plastic casing with hinge-type draw bar, it is characterized in that: described draw bar is hinge-type draw bar, include draw bar active page and draw bar fixed page, draw bar active page and draw bar fixed page are arbitrarily angled orientable hinged setting, and described draw bar fixed page is connected with snap close.By adopting such scheme, the present invention overcomes the deficiency that prior art exists, a kind of tripping can either pinned in breaker mechanism is provided, can be rotated by hinge again, control the subtended angle of draw bar, change the impulse stroke of bimetal leaf, thus realize regulating manually or automatically, the overload meeting different current specification regulates or thermoregulator Novel plastic shell circuit breaker.

Description

A kind of breaker of plastic casing with hinge-type draw bar
Technical field
The present invention relates to a kind of breaker of plastic casing, refer to especially and utilize bimetal leaf to realize the hinge-type draw bar circuit breaker protected circuit and apparatus overload.
Background technology
In mold cased circuit breaker, when the electric current passed through in circuit breaker is greater than rated current, bimetal leaf heated bending, and amount of bow is greater than the gap between bimetal leaf and draw bar, draw bar is promoted by bimetal leaf, rotate forward and make circuit breaker tripping, thus realize the overload protection to circuit and equipment; Therefore, the gap between bimetal leaf and draw bar determines overlond trip characteristic in mold cased circuit breaker and load current value.But the draw bar of traditional mold cased circuit breaker is integral type, as shown in Figure 1, the impulse stroke that must be changed bimetallic element by attachment device be regulated, generally adopt translational movement.
The patent No. is " breaker of plastic casing " of 201120204044.8, and it also relates to the adjustment of draw bar, but this mode is complicated, and cost is high.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, a kind of tripping can either pinned in breaker mechanism is provided, can be rotated by hinge again, control the subtended angle of draw bar, change the impulse stroke of bimetal leaf, thus realize regulating manually or automatically, the overload meeting different current specification regulates or thermoregulator Novel plastic shell circuit breaker.
Realize above-mentioned purpose, the present invention adopts following technical scheme: a kind of breaker of plastic casing with hinge-type draw bar, include pedestal, snap close, draw bar and bimetal leaf, bimetal leaf can realize draw bar action and drive snap close action to make circuit breaker tripping, it is characterized in that: described draw bar is hinge-type draw bar, include draw bar active page and draw bar fixed page, draw bar active page and draw bar fixed page are arbitrarily angled orientable hinged setting, and described draw bar fixed page is connected with snap close.
By adopting the scheme of the new construction of hinge-type, the tripping in breaker mechanism can either be pinned, can be rotated by draw bar active page again, control the subtended angle of draw bar, change the impulse stroke of bimetal leaf, thus realize regulating manually or automatically, the overload meeting different current specification regulates or temperature adjustment.
The further setting of the present invention is: described draw bar active page includes active page body and hinged circle, active page body and hinged circle are fixedly installed, described draw bar fixed page includes fixed page body and clamping ring, fixed page body and clamping ring are fixedly installed, the hinged circle of described draw bar active page and the clamping ring of draw bar fixed page are coaxially arranged, and are provided with jointed shaft in its through hole formed.
By adopting such scheme, be optimize product structure further, the convenience of performance and use.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is background technology structural representation;
Fig. 2 is the overall structure schematic diagram of the embodiment of the present invention one;
Fig. 3 is the structural representation that the hinge-type draw bar of the embodiment of the present invention two coordinates with bimetal leaf;
Fig. 4 is the end view that the hinge-type draw bar of the embodiment of the present invention two coordinates with bimetal leaf.
Embodiment
As shown in Figure 2, a kind of breaker of plastic casing with hinge-type draw bar, include pedestal 3, snap close, draw bar 1 and bimetal leaf 2, bimetal leaf 2 can realize draw bar 1 action and drive snap close action to make circuit breaker tripping, these above-mentioned technical characteristics are also common in the prior art, so the present embodiment once and two in we have been not described in detail, in the present embodiment two, as shown in Figure 3 and Figure 4, described draw bar 1 is hinge-type draw bar 1, include draw bar active page 11 and draw bar fixed page 12, draw bar active page 11 and draw bar fixed page 12 are arbitrarily angled orientable hinged setting, described draw bar fixed page 12 is connected with snap close, by adopting the scheme of the new construction of hinge-type, the tripping in breaker mechanism can either be pinned, can be rotated by draw bar active page 11 again, control the subtended angle of draw bar 1, change the impulse stroke of bimetal leaf 2, thus realize regulating manually or automatically, the overload meeting different current specification regulates or temperature adjustment.
In the embodiment of the present invention two, described draw bar active page 11 includes active page body 111 and hinged circle 112, active page body 111 and hinged circle 112 are fixedly installed, described draw bar fixed page 12 includes fixed page body 121 and clamping ring 122, fixed page body 121 and clamping ring 122 are fixedly installed, the hinged circle 112 of described draw bar active page 11 is coaxially arranged with the clamping ring 122 of draw bar fixed page 12, jointed shaft 13 is provided with in its through hole formed, we can form close-fitting jointed shaft 13 and through hole interference fit in the present embodiment, jointed shaft 13 and through hole interference fit form close-fitting, more convenient when regulating draw bar active page 11 like this, not other location.
