Abstract
The invention discloses a dual-voltage dual-power single-phase bipolar security socket which comprises a panel, a push plate, two L pole protecting doors, two L pole plug bushes, an N pole plug bush, a base, a transformer, an L pole binding post, an N pole binding post, an E pole binding post, a gland and a double-break plug-in safety switch. Compared with the prior art, the invention has the following advantages: 1, by taking the dual safety protection measures of splash-proof electric-shock-proof protecting doors and safety switch, the safety is enhanced; 2,in the invention, the heavy-current double-break structured safety switch is adopted, and the moving contact plate is riveted with moving contacts, thereby enhancing the safety, increasing the current capacity and ensuring that the switch can bear 10A current; and 3, the invention improves the circuit design, so that the 110V plug bush takes power from the secondary level of the transformer and the 220V plug bush directly takes power from the external power supply, thereby increasing the current capacity of the 220V plug bush, and thus, the 220V plug bush can be used for 220V high-power electric appliances, such as hair driers and the like.
Description
Technical field
The present invention relates to the low-voltage electrical apparatus field, relate in particular to socket, specifically a kind of safety socket with the two power functions of use of two voltages.
Background technology
All to adorn shaver outlet, shaver point in the toilet, hotel; For taking into account the voltage standard of country variant and region; The shaver outlet, shaver point of all hotel dresses all has two voltages (110V and 220V) function both at home and abroad now; Be convenient to the shaver that country variant produces and use, like Chinese invention patent CN1421960A disclosed " be used in particular for electric shaver, have an independently electric current socket of retractable movable cover ".The middle 110V of this patent and the sleeve of 220V all by the transformer secondary output power supply, because the volume of transformer is less, so the coil diameter of transformer is thinner, thereby can not provide big electric current; Simultaneously do not establish the contact on its active and static contact, the contact resistance between contact is bigger, can't pass through big electric current continuously, can only singlely be used for low power shaver, and can not be used for high-power electric appliance, like hair dryer etc.Its another shortcoming is that shutter is the monolithic single open-type, and it is bigger to push stroke open, and bevel angle is less, and insertion force requires big, so latch should not insert, needs very big power to insert, and is not easy to operation.Its another shortcoming is to have only shutter, do not plug together the safety switch that pulls off, thereby fail safe is not high enough.
Other has a kind of shaver outlet, shaver point, a shaver outlet, shaver point of producing like nearest TCL company, though emergency exit also has been installed, its structure more greatly can only concealed installation in box at the bottom of 146 types, box at the bottom of inapplicable 86 types, also inapplicable high-power electric appliance uses.Because it has only a power (20W), thus also can only be used for shaver outlet, shaver point, and can't be used for more powerful electrical equipment.And use in toilet often all will be used electric cooker wind to the place of shaver outlet, shaver point in the hotel, so all will will cause the wasting of resources like this with two sockets of fashionable dress
Summary of the invention
The present invention will solve is the problem that can only singlely be used for shaver that existing pair of voltage receptacle exists, and aims to provide a kind of money and can be used for shaver, can be used for the socket of more powerful electrical equipment such as hair dryer again.
The present invention also will solve the monolithic single open-type shutter of existing two voltage receptacle existence and push power open and push the bigger problem of stroke open; Aim to provide a kind of existing waterproof and spatter the electrocution-proof protection door, the socket that plugs together the two safeguard protections of the two power of the two voltages that pull off safety switch is arranged again.
For addressing the above problem; The present invention adopts following technical scheme: the two single-phase the two poles of the earth of power of two voltages safety socket; Comprising that panel, push pedal, a L utmost point shutter, the 2nd L utmost point shutter, a L utmost point sleeve, the 2nd L utmost point sleeve, N utmost point sleeve, base, transformer, L utmost point binding post, N utmost point binding post, E utmost point binding post, gland and a double break formula plug together pulls off safety switch; It is characterized in that described each sleeve is separately positioned in the set corresponding grooves of base; Described installation gland is arranged on the bottom of base through buckle; A described L utmost point shutter, push pedal and the 2nd L utmost point shutter are successively set on the set corresponding directed moving guide rail of base, are equipped with back-moving spring on described each shutter; Described double break formula plugs together and pulls off safety switch and comprise movable contact spring, a pair of moving contact and a pair of static contact; Described a pair of moving contact is arranged on the described movable contact spring; Dispose relatively with a pair of static contact that is arranged on the base respectively; Described movable contact spring is arranged in the described push pedal, between described movable contact spring and base, also is provided with returning spring; L utmost point binding post series connection double break formula connects the end of incoming cables of current limiting switch and connects a L utmost point sleeve after plugging together and pulling off safety switch; The L utmost point of the outlet termination primary end of current limiting switch; The N utmost point of primary end connects the L utmost point and the 2nd L utmost point sleeve of transformer secondary output end, and N utmost point sleeve connects the N utmost point and the N utmost point sleeve of transformer secondary output end.
The of the present invention pair of two single-phase the two poles of the earth of power of voltage safety socket compared with prior art has the following advantages:
1 adopts two safety precautions, and the waterproof of existing shutter is spattered protection against electric shock, and safety switch is arranged again, has to have only latch to insert the charged protection against electric shock measure of back sleeve ability, has improved fail safe.
2 adopt big electric current safety switch, and sleeve just can have electricity after having only latch to insert to push shutter open, and switch adopts double break formula structure, and the movable contact spring riveting has moving contact, has increased fail safe, has strengthened ampacity, guarantees that switch can bear the electric current of 10A.
3 improve circuit design, and with the secondary power taking of 110V sleeve from transformer, the 220V sleeve increases the current capacity of 220V sleeve directly from the external power supply power taking, enables to be used for the high-power electric appliances such as electric cooker wind of 220V voltage,
As further improvement of the present invention, a described L utmost point shutter and the 2nd L utmost point shutter are biplate opposite opened structure.The insertion mouth of a described L utmost point shutter and the 2nd L utmost point shutter has guiding surface in opposite directions, also is provided with guiding surface in the described push pedal.Change the monolithic single open-type into biplate and split, it is half that the shutter stroke after the improvement has reduced, and the shutter bevel angle increases, and makes to push resistance open and reduce, and the improvement of two aspects has guaranteed that latch is easy to insert sleeve.
Further improve again as of the present invention, be equipped with buffer spring on described each static contact, make the contact of dynamic/static contact more reliable.
Further improve as of the present invention, described panel back is provided with 3 beadings and makes it to locate fully in order to push down described three sleeves.
