Abstract

A power supply converter having a retractable conducting wire includes a housing, a wire retracting box mounted in the housing and containing a restoring spring elastic piece therein, and an output conducting wire having a first end connected to the wire retracting box, and a second end connected to an output connector that may be connected to a mobile telephone, a notebook computer, a P.D.A., a digital camera, or the like. In such a manner, the output conducting wire can be wound by the wire retracting box, so that the power supply converter is portable, is easy to store, is easily packaged, and occupies little space.

Claims

1. A power supply converter having a retractable conducting wire comprising:

a housing,

a wire retracting box mounted in said housing and containing a restoring spring elastic piece therein,

a shaft,

a retracting knob, and

an output conducting wire having a first end connected to said wire retracting box, said output connecting wire having a second end connected to an output connector that is received in a DC powered electronic device;

wherein

said elastic piece in said wire retracting box biases said wire retracting box to provide a winding force that retracts said output connecting wire into said housing, and

said retracting knob is pivotally connected to an end piece;

so that

said end piece of said retracting knob provides pressure on said output connecting wire when said retracting knob is in a secure position, said end piece thereby holding said output connecting wire in a given position, and

said end piece of said retracting knob is raised when said retracting knob is moved to a released position, thereby releasing pressure on said output connecting wire so that said output connecting wire is retracted by said wire retracting box into said housing.
