Moulded case circuit breaker contact means, through the optimal design to the static contact, the flow direction of guide electric current, when the make full use of heavy current flow past, the contact was scolded out to the repulsion of electric current self production, divided disconnected circuit breaker to reach the guard action, enhanced product performance.
Description
Technical field
The utility model relates to a kind of breaker of plastic casing contact apparatus.
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; although the fixed contact that existing breaker of plastic casing configures can meet general use and performance; but performance level is not high; the wasting of resources; and the design of existing breaker of plastic casing fixed contact is not well led to the flow direction of electric current and uses; when big current flows through; the repulsion that electric current self produces cannot be made full use of; scold open contact; breaking circuit breaker reaches protective effect, and properties of product are low.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of breaker of plastic casing contact apparatus.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of breaker of plastic casing contact apparatus, be disposed with fixed contact support plate, connecting plate, U-shaped fixed head, main fixing hole, secondary fixing hole, board slot, fixed contact, rivet hole, increase magnetic sheet, moving contact, plate hole, first axis hole and the second axis hole, described fixed contact support plate is connected with U-shaped fixed head by connecting plate, described fixed contact support plate is provided with main fixing hole, secondary fixing hole is provided with on the right side of described main fixing hole, board slot is provided with in described connecting plate and U-shaped fixed head, on the upside of described U-shaped fixed head, fixed contact is installed, described fixed contact is provided with rivet hole, fixing increasing magnetic sheet on the downside of described fixed contact, moving contact is provided with on the upside of described fixed contact, plate hole is provided with on the left of described moving contact, the first axis hole is provided with on the right side of described moving contact, the second axis hole is provided with on the downside of described first axis hole.
Preferably, described main fixing hole diameter is greater than secondary fixing hole.
Preferably, described moving contact is provided with moving contact.
Preferably, described increasing magnetic sheet width is greater than moving contact width.
Preferably, described moving contact is swing mechanism.
The beneficial effect that the utility model has:
Breaker of plastic casing contact apparatus, by the optimal design to fixed contact, guides the flow direction of electric current, and make full use of big current when flowing through, the repulsion that electric current self produces, scold open contact, breaking circuit breaker reaches protective effect, enhances product performance.
Accompanying drawing explanation
Fig. 1 is the utility model breaker of plastic casing contact apparatus structural representation.
In figure: 1, fixed contact support plate, 2, connecting plate, 3, U-shaped fixed head, 4, main fixing hole, 5, secondary fixing hole, 6, board slot, 7, fixed contact, 8, rivet hole, 9, increase magnetic sheet, 10, moving contact, 11, plate hole, the 12, first axis hole, the 13, second axis 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 apparatus, is disposed with fixed contact support plate 1, connecting plate 2, U-shaped fixed head 3, main fixing hole 4, secondary fixing hole 5, board slot 6, fixed contact 7, rivet hole 8, increase magnetic sheet 9, moving contact 10, plate hole 11, first axis hole 12 and the second axis hole 13, fixed contact support plate 1 is connected with U-shaped fixed head 3 by connecting plate 2, fixed contact support plate 1 is provided with main fixing hole 4, secondary fixing hole 5 is provided with on the right side of main fixing hole 4, main fixing hole 4 diameter is greater than secondary fixing hole 5, make a distinction between the important and the lesser one like this, be convenient to fixing operation, be provided with board slot 6 in connecting plate 2 and U-shaped fixed head 3, fixed contact 7 is installed on the upside of U-shaped fixed head 3, fixed contact 7 is provided with rivet hole 8, on the downside of fixed contact 7, fixing increasing magnetic sheet 9, increases magnetic sheet 9 width and is greater than moving contact 10 width, be provided with moving contact 10 on the upside of fixed contact 7, moving contact 10 is provided with moving contact, and moving contact 10 is swing mechanism, can effective lifting operation precision, be provided with plate hole 11 on the left of moving contact 10, be provided with on the right side of moving contact 10 on the downside of first axis hole 12, first axis hole 12 and be provided with the second axis hole 13.
Operation principle: breaker of plastic casing contact apparatus electric current flows into through fixed contact 7, then flow out through moving contact 10, such conduct current, make fixed contact 7 and moving contact 10 produce the electromagnetic force that phase mutual exclusion is opened, also can establish below fixed contact 7 simultaneously and increase magnetic sheet 9, the electromagnetic force that fixed contact 7 produces is concentrated on this region; Like this when large fault current passes through, can scold more rapidly and start contact 10, timely open failure circuit, plays a protective role.
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.
