At present, the popularity rate of notebook computer is very big, and notebook computer brings to people and very big convenience with characteristics such as its mobility, small and exquisite, practicalities.Yet, cause its frequent charge of having to just because of the mobility of notebook computer, and power line also should have enough length.The power line that is used for notebook computer charging at present is an on-telescopic, and this just often causes the trouble of coiling, and depositing after power line uses also be very much inconvenient, and this trouble of bringing because of power line and the convenience of notebook computer itself do not match very much.Even be improved to extension type by the power line that improves present notebook computer, the situation of coiling still inevitably appears, can not deal with problems at all.
Three, summary of the invention:
The present invention be directed to the defective and the deficiency that exist in the prior art, a kind of telescopic power cord of notebook computer is provided.
Technical scheme:
A kind of telescopic power cord of notebook computer, comprise transformer, be connected interchange lead and the plug and the low-voltage direct lead and the plug that are connected the transformer other end of transformer one end, also comprise a cylindrical case, described transformer coupling is set in the cylindrical case stage casing and cylindrical case is divided into be positioned at the interchange conductor chamber of transformer one end and the low-voltage direct conductor chamber of the transformer other end, described interchange lead and low-voltage direct lead are the scalable lead of spring-like, and the interchange lead lays respectively at the low-voltage direct lead and exchanges in conductor chamber and the low-voltage direct conductor chamber.
Described cylindrical case is one and exchanges conductor casing, transformer case, tubular low-voltage direct conductor casing by tubular and dock the combination shell of forming successively.
One end of described transformer case is provided with three hole plugs, the other end is provided with the direct current jack, the three hole jack couplings that three hole plugs exchange with described tubular on the conductor casing are installed together, and the DC plug coupling on direct current jack and the described tubular low-voltage direct conductor casing is installed together.
Exchange between conductor casing and the transformer case at tubular, be respectively equipped with outer tube between transformer case and the tubular low-voltage direct conductor casing.
Described outer tube one end is connected on the transformer case, and the other end exchanges conductor casing or tubular low-voltage direct conductor casing by being threaded with tubular.
Described shell is the cylindrical tube shape shell, perhaps is the square column cylindrical case, perhaps is positive six rib cylindrical cases.
Beneficial effect of the present invention:
1, telescopic power cord of notebook computer of the present invention has advantage easy to use, and the problem of coiling takes place anything but, increases in the travelling way protection to electric wire in addition.
2, telescopic power cord of notebook computer of the present invention can also improve making it become composite type slightly to its structure, so that more convenient to carry and preservation.
3, telescopic power cord of notebook computer of the present invention is simple in structure, manufactures easily, and result of use is good, is beneficial to very much promotion and implementation.

Five, embodiment:
Embodiment one: referring to Fig. 1, Fig. 2, a kind of telescopic power cord of notebook computer, comprise a cylindrical tube shape shell, transformer 3 also is designed to cylindrical, transformer 3 couplings are set in the cylindrical case stage casing, be positioned at the interchange conductor chamber 2 of transformer one end and the low-voltage direct conductor chamber 2 ' of the transformer other end thereby cylindrical case is divided into, be respectively equipped with dividing plate 10 between transformer chamber, interchange conductor chamber 2, the low-voltage direct conductor chamber 2 ' in the present embodiment.Be connected with interchange lead 4 and ac plug 5 at transformer 3 one ends, be connected with low-voltage direct lead 4 ' and direct current plug 6 (a kind of form that only shows DC plug among the figure) at transformer 3 other ends.Described interchange lead 4 and low-voltage direct lead 4 ' are the scalable lead of spring-like, and interchange lead 4 lays respectively at low-voltage direct lead 4 ' and exchanges in conductor chamber 2 and the low-voltage direct conductor chamber 2 '.The respective wire that stretches respectively in use makes it be elongated to Len req and gets final product, when not using with in its reduction suit and the shell separately.
Embodiment two: accompanying drawing is not drawn, and meaning and embodiment one are basic identical, and something in common does not repeat, and different is: between transformer chamber, interchange conductor chamber 2, the low-voltage direct conductor chamber 2 ' dividing plate is not set in the present embodiment.
Embodiment three: referring to Fig. 3, number identical with embodiment one, same meaning, something in common does not repeat, and different is: described cylindrical case is one and exchanges conductor casing 2a, transformer case 1 ', tubular low-voltage direct conductor casing 2b by tubular and dock the combination shell of forming successively.Wherein an end of transformer case 1 ' is provided with three hole plugs 7, the other end is provided with direct current jack (perhaps DC plug), three hole jacks, 8 couplings that three hole plugs 7 exchange with described tubular on the conductor casing 2a are installed together, and DC plug 9 (the perhaps direct current jack) coupling on direct current jack (perhaps DC plug) and the described tubular low-voltage direct conductor casing 2b is installed together.
