Abstract
A mobile phone charger with telescopic wire belongs to communication equipment auxiliary device. A fixed shaft if mounted in the housing, a wire roller is mounted round the fixed shaft. The two ends of a wrest spring are respectively connected with the fixed shaft and the wire roller. The wire winds round the wire roller with one end connected to an elastic slide touch head fixed on the wire roller. An annular seat is fixed with direct current input ring and output ring that contact with the elastic slide touch head. The wires of the charger are respectively connected to the direct current input ring and output ring. The charger can automatically put its long wire in the housing when it is not working. The charger has the following advantages: simple structure, neatness appearance, convenient use, easy in keeping and taking, long use life.
Description
Technical field
The utility model belongs to the Communication Equipment auxiliary equipment, relates generally to charger for mobile phone.
Background technology
At present, the lead of most charger for mobile phone all exposes in the charger for mobile phone outside, and can not be recovered in the charger housing, wrapping phenomena often takes place in lead, extremely inconvenient during use, also be difficult for taking care of and carrying, and cause harness damage easily, reduced the useful life of charger.
Summary of the invention
The purpose of this utility model is exactly the technical problem that exists at above-mentioned existing charger for mobile phone, and the charger for mobile phone that design provides a kind of lead to stretch reaches use, carries and take care of purpose convenient, that reduce the damage probability, increase the service life.
Basic design of the present utility model is, equipped fixed axis in housing, the Wire guide roller that the surface is provided with helix groove is sleeved on the fixed axis, the torsion film two ends are affixed with fixed axis and Wire guide roller respectively, lead is wrapped on the Wire guide roller surface, its inner end two the end of a thread respectively be packed in the Wire guide roller sidewall on two Elastic Sliding contacts be connected, on ring seat, install direct current input ring and direct current output ring, two the ring respectively with two Elastic Sliding contact contact matching, the charger lead is affixed logical with direct current input ring and output ring respectively, on housing, also be equipped with locking assembly and elastic guide pressing plate, so far constituting the charger for mobile phone that lead can stretch.
The utility model can all be stored in the housing long lead of charger when not charging automatically, appearance is neatly agile, easily lead is pulled out during charging, length is controlled, has characteristics simple in structure, easy to use, that be easy to keeping and carry, increase the service life.
