Protecting device for electrical cable

Abstract

A protecting device for electrical cable is provided, which is disposed in an electronic device with two bases pivotally connected to each other. Each of the bases has a pivot portion, and the pivot portions are pivotally connected to each other. The protecting device is disposed across the two pivot portions for an electrical cable passing through. Then the cable is protected by the protecting device, and is prevented from being worn and damaged due to relative rotation of the two bases. Thus the lifetime of the electrical cable is extended.

DETAILED DESCRIPTION OF THE INVENTION

In order to have a further understanding of objects, construction, characteristics, and functions of the invention, the invention is illustrated in detail accompanied with embodiments as follows.

Referring to FIGS. 3A and 3B, FIG. 3A is a perspective view of the protecting device of a first embodiment the present invention, and FIG. 3B is a partial enlarged view of FIG. 3A

The protecting device 20 for an electrical cable of the first embodiment is a hollow tube with a hollow passing portion 2011, and two ends of the tube 201 are respectively a first opening 2012 and a second opening 2013. An annular coupling portion 202 is formed on the external peripheral of the tube 201, which is an annular flange protruding form the external peripheral of the protecting device 20.

The protecting device 20 for an electrical cable of the embodiment of the present invention is disposed in an electronic device 30, wherein a first pivot portion 3011 is formed on a first base 301, and both ends of the first pivot portion 3011 are respectively provided with a positioning surface 3012. The protecting device 20 is disposed in the first pivot portion 3011 and protruding outward with its coupling portion 202 pressing against the positioning surface 3012 of the first pivot portion 3011 for the protecting device 20 being coupled with the first base 301 and positioned.

Referring to FIGS. 4A and 4B, an electronic device 30 of a second embodiment of the present invention is provided. The electronic device 30 includes a first base 301 and a second base 302 pivotally connected to each other, so that the first base 301 may be rotated relative to the second base 302.

The first base 301 has a first pivot portion 3011, and the second base 302 has two second pivot portions 3021. The first pivot portion 3011 is located between the two second pivot portions 3021, thus first pivot portion 3011 is adjacent to and pivotally connected to the two second pivot portion 3021.

The protecting device 20 is disposed across the first pivot portion 3011 and one of the two second pivot portions 3021, and its passing portion 2011 is for an electrical cable 303 passing through. Two ends of the electrical cable 303 are respectively connected to the first base 301 and the second base 302. Thus the protecting device 20 prevents the electrical cable 303 from being worn and damaged by the friction generated by the relative rotation of the first base 301 and the second base 302. Then the lifetime of the cable 303 is effectively extended. Moreover, the electronic device 30 as described above refers to a flip-up electronic device, for example, a notebook, PDA (Personal Digital Assistant), cellular phone, or GPS Navigator (Global Positioning System Navigator), etc.

Referring to FIG. 5, a protecting device 40 of a third embodiment of the present invention is provided. The protecting device 40 for an electrical cable is a hollow tube with a hollow passing portion 4011, and two ends of the protecting device 40 are a first opening 4012 and a second opening 4013 respectively. Also, an annular coupling portion 402 is formed on the external peripheral of the tube 401. The first opening 4012 and the second opening 4013 are diverging nozzles, such that the cable may pass through the passing portion 4011 smoothly and friction generated is reduced. Moreover, the tube 401 can be made of a flexible material so as to reduce the damage due to friction.

Above all, through the implementation of the protecting device for electrical cable according to the present invention, the electrical cables can be effectively protected, such that their lifetime can be extended, which indeed effectively protects the electrical cables.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
