Description
Technical field
The utility model relates to a kind of breaker of plastic casing contact can scold device.
Background technology
Circuit breaker is the electric current that namely can carry and cut-off under normal loop condition; also can carry and cut-off the switching device of the electric current under abnormal loop condition at the appointed time; breaking capacity is the main performance index of circuit breaker always; and the problem that existing circuit breaker ubiquity breaking capacity is low; and the circuit breaker cost of point broken height is high; both cannot meet market demands, thus cannot meet the demand of high-end market, so the circuit breaker that research invents a kind of resolution capability high becomes top priority.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, and providing a kind of breaker of plastic casing contact can scold device.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of breaker of plastic casing contact can scold device, be disposed with fixed contact support plate, connecting plate, U-board, quiet silver contact, dynamic silver contact, moving contact, plate hole, first axle, second axle, spring, 3rd axle, rotating shaft and actuator hole, it is characterized in that: described fixed contact support plate is connected with U-board by connecting plate, dynamic silver contact is provided with on the upside of described quiet silver contact, and dynamic silver contact is fixed on moving contact, plate hole is provided with on the left of described moving contact, first axle is installed on the right side of described moving contact, the second axle is provided with on the downside of described first axle, described second axle is connected with the 3rd axle by spring, rotating shaft is provided with on rear side of described moving contact, described rotating shaft is provided with actuator hole.
Preferably, described quiet silver contact width is greater than dynamic silver contact width.
Preferably, described first axle, the second axle and the 3rd axle are provided with axle sleeve.
Preferably, described rotating shaft is provided with power transmission shaft.
Preferably, described moving contact is swing mechanism.
Preferably, described spring forms spring knuckle at the second axle place.
The beneficial effect that the utility model has: breaker of plastic casing contact can scold device, when circuit breaker has a large fault current, moving contact can be subject to the electrodynamic repulsion force that electric current self produces, rotate centered by the first axle, when the second axle rotates through spring knuckle top with moving contact, under the reaction of spring, moving contact is made rapidly to rotate up, point deenergizing fast, the breaking capacity that breaker of plastic casing contact can scold device to improve, but it is also relatively simple not increase the part of contact apparatus, structure, and cost free increases.
Accompanying drawing explanation
Fig. 1 is that the utility model breaker of plastic casing contact can scold apparatus structure schematic diagram.
In figure: 1, fixed contact support plate, 2, connecting plate, 3, U-board, 4, quiet silver contact, 5, dynamic silver contact, 6, moving contact, 7, plate hole, the 8, first axle, the 9, second axle, 10, spring, the 11, the 3rd axle, 12, rotating shaft, 13, actuator hole.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.
As shown in Figure 1, a kind of breaker of plastic casing contact can scold device, is disposed with fixed contact support plate 1, connecting plate 2, U-board 3, quiet silver contact 4, dynamic silver contact 5, moving contact 6, plate hole 7, first axle 8, second axle 9, spring 10, 3rd axle 11, rotating shaft 12 and actuator hole 13, fixed contact support plate 1 is connected with U-board 3 by connecting plate 2, dynamic silver contact 5 is provided with on the upside of quiet silver contact 4, quiet silver contact 4 width is greater than dynamic silver contact 5 width, prevent from like this causing contact skew, and dynamic silver contact 5 is fixed on moving contact 6, moving contact 6 is swing mechanism, can flexible operation, be provided with plate hole 7 on the left of moving contact 6, install on the right side of moving contact 6 on the downside of first axle 8, first axle 8 and be provided with the second axle 9, second axle 9 is connected with the 3rd axle 11 by spring 10, and the first axle 8, second axle 9 and the 3rd axle 11 are provided with axle sleeve, can prevent axle from wearing and tearing like this, spring 10 forms spring knuckle at the second axle 9 place, equipment is operated smoothly, is provided with rotating shaft 12, rotating shaft 12 is provided with actuator hole 13 on rear side of moving contact 6.
Operation principle: novel contact device forms primarily of fixed contact, moving contact 6, first axle 8, second axle 9, the 3rd axle 11, spring 10, when circuit breaker is in "on" position, second axle 9 acts on the right of spring knuckle, when circuit breaker has large fault current, moving contact 5 can be subject to the electrodynamic repulsion force that electric current self produces, rotate centered by the first axle 8, when the second axle 9 rotates through spring knuckle top with moving contact 6, under the reaction of spring 10, make rapidly moving contact 6 rotate up, divide deenergizing fast.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
