ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fastening device and more particularly to a cable fastening device for computer peripheral such as a keyboard.
2. Description of Related Art
A conventional cable fastening mechanism of keyboard la is shown in
FIG. 1
wherein left and right grooves
11
a
and
12
a
each having an equal predetermined length are provided on a side of the bottom of the cable connected keyboard
1
a
whereby cable
13
a
may be received in either left groove
11
a
or right groove
12
a
prior to extending therefrom. Such arrangement has the advantage of preventing cable from breaking when pulling. But this fastening mechanism is unsatisfactory for the following reasons:
1. A sufficient width and depth of the groove
11
a
or
12
a
is required in order to be adapted to various cables
13
a.
However, this precision is not obtainable easily.
2. It is still possible of breaking the cable
13
a
due to cable
13
a
is bent about 90 degrees.
3. The provision of left and right grooves
11
a
and
12
a
wastes a precious space of the bottom of keyboard
1
a.
Such is especially undesirable in a narrowed cable entry and withdrawal area.
Thus, it is desirable to provide an improved cable fastening device in order to overcome the above drawbacks of prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a cable fastening device which is realized by providing a cable positioning means pivotal with respect to the attached fastening device such that cable is capable of turning about fastening device in a limited range. Such cable fastening device has the advantages of making cable uneasy to break, adapted to various cables, no sharp bending of cable, suitable to be used in narrowed cable entry and withdrawal area, fixing fastening device by means of pivotal means, improving the the quality of signal received by wire or wireless technique, and readily adapted to various operating environments.
