Abstract:
1. A device for detecting whether a power cable having two four-pin connectors in a computer is malfunctioned or not without using a meter, either connector having a first positive pin as a positive pin of a 12V power cable portion of the power cable, a first negative pin as a negative pin of the 12V power cable portion, a second positive pin as a positive pin of a 5V power cable portion of the power cable, and a second negative pin as a negative pin of the 5V power cable portion, comprising: a circular positive section; a positive aperture enclosed by the positive section; a positive connection having one end electrically coupled to the positive section; a circular negative section electrically coupled to the other end of the positive connection; a negative aperture enclosed by the negative section; a resistor provided on the positive connection; a light-emitting member provided on the positive connection; and first and second apertures proximate the negative aperture; wherein in a coupled state of the detection device and one connector of the power cable, the positive aperture is put on the first positive pin, the negative aperture is put on the first negative pin, the second aperture is put on the second negative pin, and the first aperture is put on the second positive pin so as to electrically couple the first positive pin to the positive section and electrically couple the first negative pin to the negative section, thereby causing the light-emitting member to emit light if the electrical connection of the 5V power cable portion is not broken.
