At least one set of power transmission cable is electrically coupled to a power supply and an electronic device powered by the power supply. The power supply has a power output port. The power transmission cable comprises: a connector comprising a first connect part, a second connect part, and a third connect part vertical to the first connect part and utilized to insertedly joint to the electronic device; and an electrically-conductive line, which is electrically coupled to the second connect part and has an electric plug, wherein the first connect part is electrically coupled to the power output port of the power supply or separably and electrically coupled to the electric plug of the precedent electrically-conductive line to enable the user to determine the length and quantity of the power transmission cable to be connected according to the quantity of the electronic devices.
This application is a continuation-in-part, and claims priority, of from U.S. patent application Ser. No. 11/107,930 filed on Apr. 18, 2005, now U.S. Pat. No. 7,101,221, entitled “Power transmission cable”.
The present invention relates to a power transmission cable, particularly to one that electrically interconnects a power supply and electronic devices powered by the power supply.
The primary objective of the present invention is to provide a separable power transmission cable, which comprises: a connector, which has a first connect part, a second connect part, a third connect part utilized to insertedly joint to an electronic device; and an electrically-conductive line, which is electrically coupled to the second connect part and has an electric plug, wherein the first connect part is electrically coupled to a power output port of a power supply, or separably and electrically coupled to the electric plug of the precedent electrically-conductive line to enable the user to determine the length and quantity of the power transmission cable to be connected according to the quantity of the electronic devices so that the problems resulting from the inseparable redundant cable in the conventional power transmission cable can be avoided.
FIG. 1 is the schematic diagram showing the connection of the conventional power cable.
The detailed technical contents of the present invention will be described below in cooperation with the drawings.
A. In the embodiment shown in FIG. 3 and FIG. 4, the first connect part 211, which is separably and electrically coupled to the power output port 101 of the power supply 10. The electrically-conductive line 22 is normally and electrically coupled to the second connect part 212 via a fixed-connection technology, such as weld joint, press joint, etc. The second connect part 212 is disposed horizontally with respect to the first connect part 211. It is obvious for this embodiment that the user can determine the overall length of the power transmission cable 20 in assembly or in separation according to the positions where the power output port 101 of the power supply 10 or each segment of electrically-conductive line 22 of the power transmission cable 20 connects with the connector 2 a. Thus, the user can determine the length and quantity of the power transmission cable 20 to be connected according to the quantity of the electronic devices so that the problems resulting from the inseparable redundant cable in the conventional transmission power cable can be avoided. Further, as the third connect part 213 is disposed vertically with respect to the first connect part 211 to insertedly joint to the electronic device, and as the assembled overall power transmission cable 20 is in apposition, cable management will be easily performed.
B. In comparison with the precedent embodiment, in the embodiment shown in FIG. 5 and FIG. 6, the end of the electrically-conductive line 22 further has an electric plug 222, which can be separably and electrically coupled to the second connect part 212 of the connector 2 b, i.e. the second connect part 212 functions as an insertion-joint port, which enable the present invention to be more flexible in application.
C. In the embodiment shown in FIG. 7, the first connect part 211, which is electrically coupled to the power supply 10, is normally and electrically coupled to the power-output line 11 via a fixed-connection technology, such as weld joint, press joint, etc. The rest is the same as mentioned above.
D. The embodiment shown in FIG. 8 demonstrates: in addition to the power transmission cable 20 of 4PIN AT/ATX specification, it is obvious for the present invention to apply to the power transmission cable 20 of other specifications, which is exemplified by the connector 2 c having the third connect part 213 of SATA specification connector in FIG. 8.
E. The embodiment shown in FIG. 9 illustrates: the second connect part 212 of the connector 2 d can also be disposed vertically with respect to the first connect part 211, which can also achieve the efficacy of the separable power transmission cable 20 of the present invention.
F. The embodiment shown in FIG. 10 illustrates: the first connect part 211 or the second connect part 212 of the connector 2 e can also be disposed obliquely with respect to the third connect part 213 so that the present invention can meet different insertion modes of various electronic devices.
Those described above are only the preferred embodiments of the present invention but not intended to limit the scope of the present invention. Any equivalent modification and variation according to the spirit of the present invention are to be included within the scope of the present invention.
