Abstract

The utility model discloses a power supply adaptor with a plurality of civil electric plugs of different national standards, which is applied to mini type electric appliances. A housing of the adapter is divided into an upper part and a lower part, wherein a plurality of civil electric plugs are arranged in the upper housing, and the inner part of the lower housing is provided with a power supply transformer, an adapter circuit board and an output low-voltage power supply plug. The upper housing can rotate freely, and a frame-shaped window is arranged on the upper housing. When rotate with the upper housing, the plugs of different kinds can expose in turn and the required plug can be selected and pulled out for use. The utility model overcomes the shortages that the existing power supply adapter can not be universally used at different regions on the world, when used, a side socket is covered by the adaptor body.

Description

Power supply adaptor

Technical field

The utility model relates to the power supply adaptor that a kind of compact electric apparatus uses, and the civilian plug and the plug that especially have a plurality of country variant standards separate the power supply adaptor that uses with body.

Background technology

The effect of power supply adaptor is that mains voltage is converted to the low-tension supply that compact electric apparatus uses, for uses such as mobile phone, digital camera, hand-held computers.Though the present commercially available most of mains voltage scopes that can bear 100V～240V of power supply adaptor, basically contained the power standard in most area in the world, but at present in the world wide, the plug of civilian electricity, socket standard and disunity, country variant and area exist very big difference, such as all being homalocephalus, in the three-phase of Taiwan, just have one to be round end mutually at the continent three-phase.Because all there is separately standard in each country to civilian electrical socket, so the specification of unified metope supply socket is impossible.Therefore, present known power supply adaptor can not be in each department so that various countries general.Although there is adapter miscellaneous that the user can be provided on market, it is obviously very unrealistic to allow at the beginning of one the people in strange land remove to seek this adapter, and this is very inconvenient for travelling outdoors or need of work sets foot in the personage in strange land.

In addition, present known most of power supply adaptor all is a rectangular shape, and plug directly is fixed on case surface, and therefore in use adaptor body causes remaining socket to use through the position that regular meeting hides the next door socket aperture.

Summary of the invention

For overcome the existing power supply adapter can not be in the world each area general, and the deficiency of the next door of body covering in use socket aperture, the utility model provides a kind of power supply adaptor, not only has the plug that use in most countries and area, and plug is pulled out body when using, and inserts socket separately.

The technical scheme that its technical problem that solves the utility model adopts is: change the housing of adapter into upper and lower two parts, the civilian plug of at least three above country variant standards is installed in the upper shell; Power transformer, adapter circuit plate and low-tension supply plug are installed in the lower house; Upper and lower two housings is separated by interlayer board, and the centre of interlayer board has circular hole, is used to connect the connection lead between adapter circuit and the plug; Upper shell is installed on the lower house, can rotate freely.Have a shaped as frame window on the periphery of upper shell, when rotating along with upper shell, various plug can reveal in order.When choosing the plug that needs, this plug can be pulled out.In the upper shell, the civilian plug of country variant standard is located along a circumferential edge, tightens up with a coil tension spring circle on the connecting line of each plug, can freely pull out during use.Thereby reach the purpose that a plurality of country variant standard plugs select use, adaptor body to separate use with plug.

The beneficial effects of the utility model are, the attaching plug that most of countries and regions are in the world used is incorporated in the same power supply adaptor, and plug separates with body when using, and provides users with the convenient.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structure chart of the present utility model, and Fig. 1 a is the adapter overall structure, and adapter is divided into upper and lower two parts: the plug that at least three country variant standards are installed in the upper shell 11; Common power transformer, adapter circuit plate and output low-tension supply plug line are installed in the lower house 14; By interlayer board 13 separately, the centre of interlayer board 13 has circular hole, is used to connect the connection lead between adapter circuit and the plug between upper shell 11 and the lower house 14; In the present embodiment, upper and lower casing be shaped as cylinder, upper shell 11 is installed on the lower house 14, can rotate freely; Low-tension supply plug cord 15 is the output of adapter, draws from lower house 14, is connected to compact electric apparatus equipment during use.Have a shaped as frame window 12 on the circumferential edge of upper shell 11, rotate with upper shell 11, when rotating along with upper shell, various plug can reveal in order.When choosing the civilian plug of location standard, this plug is just pulled out and can be used.Therefore, the size of shaped as frame window 12 is advisable with finger plug is pulled out.

Fig. 1 b has described the mounting means of upper shell 11 inner a plurality of country variant standard plugs, used the civilian plug 16 of four kinds of country variant standards in the present embodiment, being cross locatees by a circumferential edge, be installed on the interlayer board 13, the external diameter of its circumferential edge is advisable not hinder upper shell 11 to rotate freely.A coil tension spring circle 17 is arranged on the connecting line of each plug, and its effect is to have certain elasticity, but elasticity is not again very big.When the user uses, can very easily plug be extracted out, be inserted on the socket on the metope.And the elastic force of connecting line is just between the tension force of manual pulling force and wall jack.The user can extract plug out easily like this, uses up the back and only need pull up plug, and the elastic force of connecting line just can make plug be withdrawn in the upper shell 11 automatically.Because plug design becomes built-in, therefore, a kind of plug in use, can prevent other three kinds of plugs simultaneously charged causing hurt sb.'s feelings.On the other hand, avoid adaptor body to block other jack on the power socket board owing to built-in plug no longer is installed in adapter shell surface, thereby socket is fully used.

Fig. 2 is actual user mode figure, and the civilian plug that only needs to meet the socket standard is just pulled out and can normally be used from the shaped as frame window of upper shell, and unwanted plug then shields in upper shell, prevents that the human body contact from damaging.

Used the civilian plug of four kinds of country variant standards among the embodiment of the present utility model, the foundation of its design is because world wide interpolation block form mainly contains following three kinds at present:

1. flat latch pattern, the country of employing mainly contains: China, the U.S., Japan, Australia, Canada;

2. circular and rectangle latch pattern, the country of employing mainly contains: Britain, India, South Africa, Pakistan;

3. barrel band pattern, the country of employing mainly contains: European countries such as Germany, France, Italy, Switzerland;

Therefore, if above-mentioned three kinds of main plug forms are combined, can satisfy the instructions for use of most of countries and regions.
