Embodiment
The present invention is a kind of electromagnetic switch, and the electromagnetism in the especially all kinds of auto parts and components is swung to formula automobile start power supply magnetic force master switch, is the significant improvement of on the basis to existing automobile start power supply magnetic force master switch, making, and has very important practice significance.
Electromagnetism is swung to formula automobile start power supply magnetic force master switch; It is the technological revolution again of all kinds of automobile start power supply magnetic force master switchs field; It not only helps low-carbon environment-friendly; Simultaneously also energy-conservation, also be to install to hide property, installation position randomness, product work useful life longevity and the comparatively ideal a kind of high in technological content product of security reliability.It takes advanced science and technology, and is well-designed, makes the whole assembling of product parts few; Cut spring and contact stage clip are not adopted in the clutch of switch contact fully, adopt the physical electronic automatic clutchization fully, thereby make the production assembly technology simple; Production cost reduces; Electromagnetic switch starting is kept operating current and is reduced, and has also realized that the product bulk temperature that works long hours is constant simultaneously, has also just guaranteed the normal useful life of producing.So production assembling of the present invention is simple, need not debug, a dress, be fit to batch process.Also be the low ideal product with environmental protection and energy saving of production cost, the optimal power supply magnetic force of low-carbon (LC) storage battery automobile start power supply magnetic force master switch master switch especially.
The contact area that electromagnetism reversing switch product switch of the present invention is decided moving contact is 30mm * 5mm; Contact conductive plate sectional area is 30mm * 3mm; Allowing through specified direct current [DC] loaded work piece electric current is 300A [peace], 8.5KW when maximum 400A [peace], switch contact nominal load: DC28V ± 03V [kilowatt]; Maximum 12KW [kilowatt], switch starting is kept operating current≤400mA [milliampere].
Electromagnetism reversing switch of the present invention is that a kind of electromagnetism is swung to formula automobile start power supply magnetic force master switch, is that a kind of big merit electromagnetism of automobile start power supply magnetic force master switch environmental protection and energy saving is swung to formula power supply magnetic force master switch.The clutch of its switch contact, it neither adopts and separates the top spring, does not adopt the contact to close a stage clip again, so its whole accessory is few, produce the assembly technology letter but, feed consumption is few, production cost is low.Switch contact can carry 12 kilowatts [KW] of [DC] load, and starting is kept operating current [DC] and is 0.4 peace [A] to the maximum, and the switch contact clutch is safe and reliable rapidly; The function that also has heatproof oil resistant water proof and dust proof antivibration.It is a desirable environmental protection and energy saving product.It also is the optimal startup power supply master switch of new energy battery automobile.
Electromagnetism described in the present invention is swung to and is; The solenoid energising just makes electromagnetism swing to permanent strong magnet inverted running.Power supply magnetic force master switch of the present invention is; The solenoid break-make electricity generation of no magnetic there are electromagnetic force and non-electromagnetic-force, make the closed conducting of normally opened contact or the disconnection of power supply magnetic force master switch, just be power supply magnetic force master switch.
The structure of product of the present invention and operation principle are explained as follows:
As shown in Figure 1; Electromagnetism reversing switch of the present invention; Because also possessed solenoid break-make electricity generation that not have magnetic electromagnetic force and non-electromagnetic-force are arranged; Make the closed conducting of normally opened contact or the disconnection of power supply magnetic force master switch; Therefore be also referred to as electromagnetism and swing to formula automobile power source magnetic force master switch, at first when not starting, the S utmost point of the permanent strong magnet 08 in this electromagnetism reversing switch is tightly to inhale being wound in the not solenoid of energising on the coil insulation skeleton 12 promptly to start on the electromagnetic core 14 of solenoid 11; And the electromagnetic core 14 no electro permanent magnetic of this moment when 11 energisings of starting solenoid, just produce the extremely identical electromagnetic pole S of S with permanent strong magnet 08 on the nonmagnetic electromagnetic core 14 of starting solenoid 11.According to the law of magnetism; The magnetic force of the same sex repels each other, and the magnetic force of the opposite sex protects attraction mutually.So permanent strong magnet 08 receives the effect of electromagnet same sex magnetic force, moving contact location navigation 06 and moving contact location M4 screw rod 09 and assisting down at fixed contact location navigation and fixed contact fixing glue timbering; Track according to setting is swung to operation, overlaps with the position of setting, and overlapping the position is exactly the fixed contact of electromagnetic switch; Promptly; 400A conduction fixed contact connecting plate 02, said fixed contact is positioned on the fixed contact bakelite support 03, and moving contact is that the 07-400A moving contact is just on the N magnetic pole of permanent strong magnet 08 iron core; Deciding the coincidence of moving contact, is exactly the closed conducting of deciding moving contact that electromagnetism is swung to formula automobile start power supply magnetic force master switch.When 11 outages of starting solenoid; Just lose same sex magnetic force on the electromagnetic core 14 of starting solenoid 11; So the strong magnet S utmost point effect of being started the no magnetoelectricity magnetic core of solenoid 11 is for a long time left the coincidence position of setting, with the tightly adhesive of no magnetoelectricity magnetic core of starting solenoid 11; The process of adhesive, just electromagnetism is swung to the disconnection of the closed conducting contact of formula power supply magnetic force master switch.So circulation has just formed electromagnetism and has swung to formula automobile start power supply magnetic force master switch.
In addition; Also be provided with the product mounting bracket of being convenient to install 13, sealing washer 04 and M4 nut and the spring pad 01 that M4 standing screw 05 cooperates with M4 standing screw 05 at electromagnetism reversing switch of the present invention, and the shielding outer cover 10 that does not receive electromagnetic interference that effectively guarantees properties of product.
The description of above-mentioned preferred embodiment makes those skilled in the art can make or use the present invention.The various modifications of these embodiment are conspicuous for a person skilled in the art, and the General Principle of definition can be applied among other embodiment and do not deviate from the spirit or scope of the present invention here.Therefore, the embodiment that the present invention is not limited to illustrate here, and will meet and the principle and the novel feature the most wide in range consistent scope that disclose here.
