Abstract
The utility model relates to a molded case circuit breaker, and particularly relates to a circuit breaker with a hinge type traction rod capable of realizing overvoltage protection for circuits and equipment by using a bimetallic strip. The adopted technical scheme is that the molded case circuit breaker with the hinge type traction rod is characterized in that the traction rod is the hinge type traction rod and comprises a traction rod movable hinge and a traction rod fixed hinge, the traction rod movable hinge and the traction rod fixed hinge are in hinged connection capable of being positioned in any angle, and the traction rod fixed hinge is connected with a buckle. The molded case circuit breaker with the hinge type traction rod overcomes defects existing in the prior art through adopting the scheme provided by the utility model, and provides a novel molded case circuit breaker which not only can lock tripping in a circuit breaker mechanism, but also can control the flare angle of the traction rod and change the operating stroke of the bimetallic strip through hinge rotation, thereby realizing manual or automatic adjustment, and meeting requirements of overvoltage adjustment or temperature adjustment with different current specifications.
Description
Technical field
The utility model relates to a kind of breaker of plastic casing, refers to especially and utilizes 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 passing 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 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 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 by attachment device, change the impulse stroke of bimetallic element, generally adopt translation mode.
The patent No. is 201120204044.8 " breaker of plastic casing ", and it also relates to the adjusting of draw bar, but this mode is complicated, and cost is high.
Summary of the invention
The utility model 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 manually or automatically, regulate, the overload that meets different current specification regulates or thermoregulator Novel plastic shell circuit breaker.
Realize above-mentioned purpose, the utility model 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 be realized 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, can either pin the tripping in breaker mechanism, can rotate by draw bar active page again, control the subtended angle of draw bar, change the impulse stroke of bimetal leaf, thereby realize manually or automatically, regulate, the overload that meets different current specification regulates or temperature adjusting.
Further setting of the present utility model 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 utility model is further described.
Accompanying drawing explanation
Fig. 1 is background technology structural representation;
Fig. 2 is the overall structure schematic diagram of the utility model embodiment mono-;
Fig. 3 is the structural representation that the hinge-type draw bar of the utility model embodiment bis-coordinates with bimetal leaf;
Fig. 4 is the end view that the hinge-type draw bar of the utility model embodiment bis-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 be realized draw bar 1 action and drive snap close action to make 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, by adopting the scheme of the new construction of 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 manually or automatically, regulate, the overload that meets different current specification regulates or temperature adjusting.
In the utility model embodiment bis-, 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, in the through hole of its formation, be provided with jointed shaft 13, we can form close-fitting jointed shaft 13 and through hole interference fit in the present embodiment, jointed shaft 13 forms close-fitting with through hole interference fit, more convenient when regulating draw bar active page 11 like this, do not want other location.
