Abstract
The invention relates to a molded case circuit breaker and especially discloses a hinged draw bar circuit breaker capable of line and equipment overload protection by using a bimetallic strip. The technical scheme adopted in the invention is as follows: the molded case circuit breaker with a hinged draw bar is characterized in that the draw bar is a hinged draw bar and comprises a draw bar movable sheet and a draw bar fixed sheet, the draw bar movable sheet and the draw bar fixed sheet are hinged and can be positioned at any one angle, and the draw bar fixed sheet is connected with a lock catch. By adopting the above scheme, the disadvantages in the prior art can be overcome, not only can the jump buckle in a circuit breaker mechanism be locked, the field angle of the draw bar can also be controlled through the rotation of the sheets, and the working stroke of the bimetallic strip can be changed, so that the hand-operated or automatic adjustment can be realized, and the over adjustment or temperature adjustment with different current specifications can be met.
Description
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 to circuit and apparatus overload protection.
Background technology
In mold cased circuit breaker, when the electric current passed through in circuit breaker is greater than rated current, the 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 and make circuit breaker tripping forward, thereby realize the overload protection to circuit and equipment; Therefore, the gap between bimetal leaf and draw bar has determined overlond trip characteristic and the load current value in the mold cased circuit breaker.But the draw bar of traditional mold cased circuit breaker is integral type, as shown in Figure 1, regulate and must change the impulse stroke of bimetallic element by attachment device, generally adopt the translation mode.
" breaker of plastic casing " that the patent No. is 201120204044.8, it also relates to the adjusting of draw bar, but this mode complexity, cost is high.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, a kind of tripping that can either pin in breaker mechanism is provided, can rotate by hinge again, control the subtended angle of draw bar, change the impulse stroke of bimetal leaf, thereby realize regulating manually or automatically, the overload that meets different current specification is regulated 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 the hinge-type draw bar, include pedestal, snap close, draw bar and bimetal leaf, bimetal leaf can realize that the draw bar action drives the snap close action and makes circuit breaker tripping, it is characterized in that: described draw bar is the 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.
The scheme of the new construction by adopting hinge-type, can either pin the tripping in breaker mechanism, can rotate by the draw bar active page again, control the subtended angle of draw bar, change the impulse stroke of bimetal leaf, thereby realize regulating manually or automatically, the overload that meets different current specification is regulated or 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 in the through hole of its formation, are provided with jointed shaft.
By adopting such scheme, be further optimize product structure, the convenience of performance and use.
Below in conjunction with accompanying drawing, the invention will be further described.
The accompanying drawing explanation
Fig. 1 is the background technology structural representation;
The overall structure schematic diagram that Fig. 2 is the embodiment of the present invention one;
The structural representation that the hinge-type draw bar that Fig. 3 is the embodiment of the present invention two coordinates with bimetal leaf;
The end view that the hinge-type draw bar that Fig. 4 is 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 the hinge-type draw bar, include pedestal 3, snap close, draw bar 1 and bimetal leaf 2, bimetal leaf 2 can realize that draw bar 1 action drives the snap close action and makes circuit breaker tripping, these above-mentioned technical characterictics are also common in the prior art, so the present embodiment once and two in we have not been 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, the scheme of the new construction by adopting hinge-type, can either pin the tripping in breaker mechanism, can rotate by draw bar active page 11 again, control the subtended angle of draw bar 1, change the impulse stroke of bimetal leaf 2, thereby realize regulating manually or automatically, the overload that meets different current specification is regulated or 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, be provided with jointed shaft 13 in the through hole of its formation, we can form close-fitting to jointed shaft 13 and through hole interference fit in the present embodiment, jointed shaft 13 forms close-fitting with the through hole interference fit, more convenient when regulating draw bar active page 11 like this, do not want other location.
