Technical field

The utility model is relevant for a kind of power-supply adapter, is meant that especially a kind of being provided with can stretch in the power-supply adapter outside and furl in the power-supply adapter of the connecting line of power-supply adapter inside.

Background technology

Some portable electronic products (as carry-on dish, mobile phone etc.) all have the battery of its specific use at present, so that the electric power of this required by electronic product to be provided, in case the power supply of battery exhausts, this electronic product is that non-transformer uses, promptly need to use power-supply adapter this moment, carries out replenishing or transmission of power supply.

Known power-supply adapter is for having a housing, and this housing one end is provided with an attaching plug, and in order to be plugged to city's power supply, this housing one side is provided with a USB slot in addition.Above-mentioned electronic installation can dispose a transmission line usually; this transmission line one end is provided with USB plug; in order to be plugged in the USB slot of housing; the other end is connected in electronic installation; by this; can the city be transferred to electronic installation with power supply via this power-supply adapter and this transmission line, with power supply or the direct power supply that replenishes electronic installation.

But, known power-supply adapter in use, the transmission line that electronic installation disposed of must arranging in pairs or groups, when the user had forgotten to carry transmission line, power-supply adapter promptly can't play a role.Therefore, the user still needs to carry in addition this transmission line except carrying the power-supply adapter, has increased user's burden virtually, and transmission line easy-to-collection not, carries inconvenient.

Therefore, the improving of this creator thoughts the problems referred to above is to concentrate on studies and cooperate the utilization of scientific principle, and proposes a kind of reasonable in design and effectively improve the utility model of the problems referred to above.

The utility model content

Main purpose of the present utility model, be to provide a kind of power-supply adapter, it is provided with rollable connecting line, and this connecting line sees through the retracting device that is arranged on this power-supply adapter inside, use and can pull out this power-supply adapter outside, or furl in the inner collection of this power-supply adapter.

A time purpose of the present utility model is to provide a kind of power-supply adapter, and it connects with different electronic installation respectively via rollable connecting line and default efferent, and power-supply adapter can be powered simultaneously to more than one electronic installation.

In order to reach above-mentioned purpose, the utility model provides a kind of power-supply adapter, comprising: a housing, and its inside is provided with a retracting device, and this housing one side is provided with a wire hole; One attaching plug, it is arranged on this housing; And a connecting line, the one end penetrates in this housing via this wire hole, and is connected with this retracting device, and this connecting line can be furled in this retracting device, and this connecting line other end connects an electric connector, and this electric connector is exposed to outside this wire hole.

The utlity model has following beneficial effect: when the utility model power-supply adapter is connected at the electronic installation with the needs charging, as long as directly pulling out the connecting line of power-supply adapter is connected with this electronic installation, can carry out the transmission of power supply, not need the transmission line that uses electronic installation to dispose; This power-supply adapter also can furl connecting line in power-supply adapter inside when not using easily automatically, and therefore, the transmission line that the user need not to carry electronic installation in addition and disposed allows power-supply adapter greatly increase in operation and the practicality of carrying.

For enabling further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Embodiment

See also Figure 1 and Figure 2, first embodiment for the utility model power-supply adapter comprises: a housing 10, an attaching plug 20, a connecting line 30 and an electric connector 40.

This housing 10 slightly is square, and these housing 10 1 sides are provided with a wire hole 11 (as shown in Figure 2), and these housing 10 opposite sides are provided with an efferent 12, and in the present embodiment, this efferent 12 is a USB slot.These housing 10 bottom surfaces 13 and indent formation one are the storage tank 14 of open shape.These housing 10 inner appropriate locations are provided with a retracting device 15, has the function that furls this connecting line 30 automatically, in the present embodiment, this retracting device 15 is a winder, when the user need not use this connecting line 30, this connecting line 30 can be seen through this retracting device 15 and furl automatically in this housing 10, above-mentioned retracting device 15 belongs to known techniques, and the utility model does not limit the structure of this retracting device 15, so no longer given unnecessary details at this.

This attaching plug 20 has two inserted sheets 21, and these attaching plug 20 rotatable being articulated on this housing 10, and this attaching plug 20 is plugged in city's power supply via this two inserted sheet 21, allows the city can see through the electronic installation that this connecting line 30 inputs to the desire charging with power supply.This attaching plug 20 can be rotated when not using and be placed in this storage tank 14.

This connecting line 30 is that an inside is provided with conductor (figure slightly) and is covered with the structure of insulating barrier (figure is slightly) in this conductor external packets, but the structure of connecting line 30 and pattern do not limit, and this connecting line 30 can be cable, winding displacement ... etc.In the present embodiment, this connecting line 30 is flat cable.

These connecting line 30 1 ends penetrate this housing 10 inside via this wire hole 11, and be connected in this retracting device 15, this connecting line 30 can furl in this retracting device 15, this retracting device 15 also waits the member electric connection with the circuit board of these housing 10 inside (figure slightly), make this connecting line 30 be electrically connected at this housing 10, and this connecting line 30 is arranged in this wire hole 11 versatilely, so that pull out this connecting line 30 outside housing 10 or be accommodated in this housing 10.

This electric connector 40 is a Mini-USB connector at present embodiment, but not as limit, this electric connector 40 also can be various connectors such as USB connector, power connector or live wire (FireWire) connector, and it can be the pattern of female seat or male.This electric connector 40 is connected in this connecting line 30 other ends, and is exposed to outside this wire hole 11.These electric connector 40 inside are provided with most terminals (figure slightly), and these terminals are to make with conductive material, and these terminals are electrically connected at these connecting line 30 conductor inside (figure slightly), make electric connector 40 be electrically connected at this connecting line 30.
