Description
Technical field
The utility model relates to household appliance technical field, relates to a kind of multifunctional power socket that possesses USB interface in the household appliance technical field specifically.
Background technology
At present, the supply socket overwhelming majority on the market is the 220V AC Power supply socket, and its structure comprises housing, attaching plug and power input line; Power input line is built in housing; Attaching plug connects power input line; Housing is provided with jack; Be provided with the sheet metal that is connected with power input line in the jack.Attaching plug is inserted power supply, and this moment, power input line just had the alternating current of 220V, just can access the power supply of 220V AC power in the plug insertion jack with household electrical appliance.This supply socket simple structure, cost are low, but function is also single, can only be applicable to the powerful household electrical appliance of eighties of last century, just seem too far behind to catch up for now increasing small-power digital product.
The small-power digital product is for example: mobile phone, MP3/MP4, digital camera etc. all are to need 3V-12V direct current supply basically, the 220V AC Power supply socket can not directly be used, therefore, manufacturer has all designed supporting charger for these small-power digital products, even the employed charger of product of same brand, different model is also different.Can often see, be covered with charger miscellaneous in a supply socket in the family, the charger that has is excessive to have taken a lot of jacks, has so not only influenced the use of other household electrical appliance, and when changing digital product, also can abandon charger simultaneously people, cause waste.
The utility model content
Technical problem to be solved in the utility model is: propose a kind of supply socket, solve AC Power supply socket function singleness of the prior art, can not satisfy the problem of the power supply requirement of increasing small-power digital product.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: supply socket comprises housing, attaching plug and power input line; Power input line is built in housing; Attaching plug connects power input line; Jack is arranged on the housing; Be provided with the sheet metal that is connected with power input line in the jack; Also comprise reduction voltage circuit, rectification circuit and USB port; Described reduction voltage circuit connects power input line; Rectification circuit connects reduction voltage circuit; Described USB port connects rectification circuit.
Further, described USB port is designed in the housing side.
Further, this supply socket also comprises trimming circuit and inching switch, and described trimming circuit connects rectification circuit, and inching switch connects trimming circuit.
Further, this supply socket also comprises storage battery, and described storage battery connects power input line and USB port.
The beneficial effects of the utility model are: increased USB port, solved the problem of AC Power supply socket function singleness, be applicable to the small-power digital product.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that circuit of the present utility model connects block diagram.
1 is housing among the figure, and 2 is attaching plug, and 3 is jack, and 4 is USB port.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model is at AC Power supply socket function singleness of the prior art, not being suitable for the small-power digital product proposes, reduction voltage circuit, rectification circuit and USB port on the basis of former AC Power supply socket, have been increased, realization is converted to low-voltage DC with the 220V alternating current, be the power supply of small-power digital product by USB port, and kept the function of original 220V AC power, very convenient.
Referring to the structural representation of Fig. 1 and the circuit block diagram of Fig. 2, the utility model comprises housing 1, attaching plug 2 and power input line; Power input line is built in housing 1; Attaching plug 2 connects power input line; Jack 3 is arranged on the housing 1; Be provided with the sheet metal that is connected with power input line in the jack 3; Also comprise reduction voltage circuit, rectification circuit and USB port 4; Described reduction voltage circuit connects power input line; Rectification circuit connects reduction voltage circuit; Described USB port 4 connects rectification circuit.
Embodiment:
Supply socket in this example comprises housing, attaching plug, power input line, reduction voltage circuit, rectification circuit, USB port, storage battery, trimming circuit and inching switch; Power input line is built in housing; Attaching plug connects power input line; Housing is provided with jack, is provided with the sheet metal that is connected with power input line in the jack; Reduction voltage circuit connects power input line, and rectification circuit connects reduction voltage circuit, and USB port connects rectification circuit and is designed in the side of housing; Trimming circuit connects rectification circuit, and inching switch is designed on the housing and connects trimming circuit; Storage battery connects power input line and USB port.
Reduction voltage circuit can adopt miniature transformer, and rectification circuit can adopt miniature rectifier, and trimming circuit can adopt variable resistor, and these all are devices common on the market, therefore no longer its structure is given unnecessary details one by one.USB port adopts standard USB2.0 interface, with its design in the housing side in order to save the space, and can keep the function of the original 220V AC power of supply socket.
Its operation principle is: when attaching plug inserts the 220V electric main, on the one hand, the enclosure interior power input line has just obtained the 220V alternating current, the sheet metal that with power input line be connected in the jack this moment has also obtained the 220V alternating current, and the plug with household electrical appliance inserts the power supply support that just can obtain the 220V alternating current in the jack so; On the other hand, the 220V alternating current is converted to low-voltage AC through reduction voltage circuit, is converted into low-voltage DC through rectification circuit again, for USB port provides low-voltage DC supply; Because the supply voltage of small-power digital product is not the same, we have designed trimming circuit and inching switch, to finely tuning through the low-voltage DC of rectification circuit output, generally can be chosen between the 3V-12V and finely tune, inching switch can be according to user's hobby selection key formula or roller type.In addition, cause supply socket to use for fear of grid cut-off, we also in the socket positioned inside storage battery, under the situation of electrical network normal power supply, this storage battery can be in charging or saturated state, when electrical network occurred cutting off the power supply unusually, this storage battery will discharge electric energy and continue as USB port low-voltage DC is provided, and is user-friendly to.
Adopt the supply socket in the utility model, the user only need be equipped with several USB interface patchcords just can be the charging of small-power digital product, simultaneously can also directly utilize the jack in the supply socket to provide the power supply support for high-power household electrical appliance, avoided on jack, sticking with the situation that charger still can't satisfy the demands in the past, the situation of also having avoided the update of factor code product and having discarded charger, save cost, also can not cause environmental pollution.
