Abstract: A connector structure for computer flat-cable, which is applied on an upper portion of a soft flat-cable usually used in a hard disc driver or a CD-ROM driver arranged in a computer and is adapted as a connection device between the mother board and the hard disc driver or the CD-ROM driver. An embodiment of the present invention is to arrange a short pin in the 28th penetration hole of the main body of the connector to make the short pin of the connector unable to penetrate through the soft flat-cable and form an open circuit between the 28th penetration hole of the connector and the judgement signal line for distinguishing a first drive and a second drive for the hard disc driver or the CD-ROM driver, for example.
