Description
Technical field
The present invention relates to a kind of switch that can switch on or off the high-tension current power supply, be specifically related to a kind of extinguishing arc contactor.
Background technology
Contactor is a kind of in order to control the electric equipment products of equipping to line powering, and it is widely used in home appliances and industrial product.In recent years, along with the development of motor vehicle (as hybrid power, fuel-cell vehicle etc.), contactor is applied as its mains switch.
The operation principle of extinguishing arc contactor is to promote push rod by moving iron core to make movable contact spring contact with fixed electrode or disconnect, realization switches on or off the high-tension current power supply, moment of separating at movable contact spring and fixed electrode and can produce electric arc between the two at this, magnetic circuit (contrary each other) and the magnetic of itself that this electric arc has been produced by two magnet steel guide (guiding on ceramic body) and eliminate, offset, and directly cause the fixed electrode external power supply be non-polar (be that power supply accesses nonpolarity requirement, former technology is just to need correct access, negative pole), thereby effectively prevent from the inner member of contactor is caused damage, use, easier for installation.But its electromagnetic component comprises iron core, coil, magnetic conduction support and lower magnetic conductive board, and magnetic conduction support and lower magnetic conductive board encase coil and iron core with Semi surrounding type, cause the leakage field phenomenon to occur, magnetic loss is large, the electromagnetism utilance is lower, thereby has affected the use of product.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and the full-enclosed extinguishing arc that a kind of magnetic loss is less, the electromagnetism utilance is high contactor is provided.
Purpose of the present invention realizes by following technical solution: a kind of full-enclosed extinguishing arc contactor, comprise electromagnetic component, moving iron core, static iron core, push rod, movable contact spring, fixed electrode, shell, ceramic body, outside this ceramic body and in the corresponding position in two outsides, end of movable contact spring, magnet steel and magnet steel frame are housed, wherein electromagnetic component comprises upper conduction magnetic board, coil and bobbin, at the interior iron ring of being peripherally equipped with of described coil, lower magnetic conductive board is housed under described bobbin, and in this, iron ring, lower magnetic conductive board and upper conduction magnetic board surround coil and bobbin entirely; Described moving iron core and static iron core are being wrapped by the iron core shell.
After adopting the present invention, because upper conduction magnetic board, interior iron ring and lower magnetic conductive board encase coil and bobbin with full enclosed integral body, dynamic and static iron core is surrounded by iron core shell and upper conduction magnetic board integral body, while making coil, the work of sound iron core, magnetic flux leakage reduces, magnetic loss is also less, thereby improved the electromagnetism utilance, promoted product quality, extended its useful life.
The accompanying drawing explanation
Below in conjunction with accompanying drawing and execution mode, the present invention is described in further detail.
The structural representation that Fig. 1 is full-enclosed extinguishing arc contactor of the present invention.
Fig. 2 is electromagnetic component in Fig. 1 and the syndeton schematic diagram between dynamic and static iron core.
Embodiment
With reference to Fig. 1, Fig. 2 is known, full-enclosed extinguishing arc contactor of the present invention, comprise electromagnetic component, moving iron core 19, static iron core 24, push rod 20, movable contact spring member 28, fixed electrode 1 (containing output), shell 2, ceramic body 4 (this fixed electrode 1 is contained on shell 2 and ceramic body 4), outside this ceramic body 4, and (the effect of having played fixing magnet steel and having extended magnetic circuit of magnet steel 6 and magnet steel frame 5 is housed in the corresponding position in two outsides, end of movable contact spring member 28, i.e. this magnet steel 6, magnet steel frame 5 is on the ceramic body 4 between ceramic body 4 and shell 2), wherein electromagnetic component comprises upper conduction magnetic board 8, coil 11 (being enamelled wire) and bobbin 9, at the interior iron ring 12 of being peripherally equipped with of described coil 11, at described bobbin, lower magnetic conductive board 14 is housed for 9 times, iron ring 12 in being somebody's turn to do, lower magnetic conductive board 14 surrounds coil 11 and bobbin 9 entirely with upper conduction magnetic board 8, described moving iron core 19 is being wrapped by iron core shell 18 with static iron core 24.
Movable contact spring member and fixed electrode separate magnetic circuit and the magnetic of itself that electric arc that moment produces produces by two magnet steel and guide (guiding on ceramic body) and eliminate, offset.For extinguishing arc, arc extinguishing better, the magnetic that is placed as of described two magnet steel 6 is arranged (two magnet steel are the arrangement of the S/N utmost point) each other in the same way.No matter two outputs of the fixed electrode of this contactor access respectively positive pole, negative pole or negative pole, the positive pole of external power supply, while in the contactor course of work, producing electric arc, at two magnet steel, produce respectively under the effect in magnetic field, capital is the two side ends discharged to ceramic body by electric arc, thereby extends the useful life of contactor.Here the nonpolarity power supply in other words referred to accesses nonpolarity requirement.
Wherein, in this side of iron ring 12 and upper conduction magnetic board 8 below blast pipe 10 is housed, for vacuumizing and the mixture such as filling hydrogen, nitrogen enclosure.Between static iron core 24, push rod 20 and moving iron core 19, return spring 23 is housed.Between the upper conduction magnetic board 8 of ceramic body 4 and electromagnetic component, square frame sheet 7 is housed.In the bottom of shell 2, base plate 16 is housed, between this base plate 16 and lower magnetic conductive board 14, cushion rubber 15 is housed.The present invention is applied to electronic capstan, winch, fork truck or electric automobile etc. to be needed to use with the power supply of high-voltage great-current.
