Description
Technical field
The present invention relates to the security protection technology of electrical appliance load.
Background technology
Having many uses of electric power plug socket is general, no matter is the electric power plug socket of family expenses, or the electric power plug socket used of enterprises and institutions, or the insert row used of research and development experimental test etc., and of a great variety, specification is multiple.The shortcoming that common double electric power plug socket exists is: 1, multiple with all shared being inserted on an electric power incoming line box of plug, only have a master switch control, not independently power control switch control.What have does not even have master switch control; 2, between the use electric loading accessing, power division is unbalanced, interacts, once one of them electricity consumption load faulty will affect other the normal use by electric loading on whole electric power plug socket; 3, after all electricity consumption load plugs insert, circuit is many and mixed and disorderly, takies very large space and very dangerous, and insert row utilance is low; 4, there is no safety precautions; 5, while use, easily by the dust of environment, smog etc. pollute and are oxidized, and cause socket contact resistance to increase, and use is absolutely unsafe; If surrounding environment has water when 6, this insert row terminal uses, easily entered by water, be short-circuited, power-off, even fire phenomena, uses and danger like this; 7, terminal shell fragment is irregular, not tight while contact with plug, and easily loosening, even loose contact, easily causes electric arc or spark, uses so abnormally dangerously, and repeatedly plug is easily loosening.
The insert row of belt switch control.Although more above-mentioned double electric power plug socket improves to some extent, and still has a lot of shortcomings.
Multiplex insert row, does not have the master switch control of electric power incoming line, only has the independent break-make of controlling each branch road.But still there are a lot of shortcoming and defect: 1, owing to there is no total power switch control, electric power plug socket is charged all the time, only has independently load break-make of each switch control, and their shortcoming is, the moment generation current electric arc of switch on and off, to causing damage by electric loading; 2, the making current capacity of switch self is unclear, can not judge the capacity requirement that load is used, and easily overload is used, and causes very large danger; 3, in the time running into one of them branch road overload short circuit fault, can affect the branch road electrical appliance load of other charged work; 4, suitable safeguard measure useless, for example, ought run into thunderbolt, and surge current impacts, and easily damages electrical equipment when the faults such as electromagnetic interference.
Its shortcoming of multipurpose socket is: 1, electrical appliance load plug is inserted on vertical socket, and lead-out wire is many and in a mess; 2.Can not independently control branch road electricity consumption, and electricity consumption load capacity is unclear, when use, easily overloads, once one of them breaks down by electric loading, can has influence on other and use electric loading; 3.The vertical placement difficulty of outlet station, takies very large space, and environment for use is restricted; 4.There is no safeguard measure, once run into thunderbolt, current surge, can not fine protection load when electromagnetic interference.
Above-mentioned various normal power supplies insert row has following subject matter in use: 1, can not security control general supply or the load switch of branch road socket; 2, there is no safety precautions, for example: overload short circuit, thunderbolt, surge current impacts, overvoltage protection, earth leakage protective, emi protection etc.; 3, terminal outlet is complicated and random, and utilance is low, places lack of standardization, not attractive in appearance; 4, terminal socket poor compatibility, form is single, there is no versatility; 5, switch on and off sound produces greatly and easily arc spark, easily causes personal safety to damage and cause the damage of electrical appliance; 6, insert row way circuit electric current and branch current capacity are unclear, and easily overload is used, very dangerous; 7, socket contact flat spring is irregular, nonstandard, coordinate with plug not close, easily loosening and sparking, danger close like this; 8, outlet socket is exposed, is easily subject to environmental pollution, enters dust foreign material, smog corrosion oxidation terminal inserted sheet, and while making to contact with plug, contact resistance increases, or loose contact, uses danger close; 9, there is no good water-proof function, because outlet socket is exposed, when around while having potential water source to enter, easily cause short circuit or fire, use is absolutely unsafe; 10, product specification kind is single, and power capacity is subject to the restriction of switch and output socket, and product uses function singleness, can not meet the chargings such as mobile phone and use.
The patent of having applied for is given an example:
Patent name: Multifunctional socket, publication number: CN2735563, this patent is the simple electrical interconnecting plate of function, its function singleness, and there is no corresponding safety precautions;
Patent name: Multi-functional combined patch panel, publication number: CN2838070, this patent is the machinery combination terminal block of simple structure, there is no electric component and protection control measure, simple insert row seat.
Although above product is widely applied, still exist above-mentioned numerous shortcoming and defect.In order to make product obtain more high-quality, safer, more convenient, more reliable, more effective use, need to explore new technical scheme and solve and realize.
