Abstract

The invention provides a short-circuit detector, which comprises at least one input port, a logic judgment circuit, a microcontroller and a display screen, wherein the input port can be connected with an output port of a device to be detected, wherein the output port is provided with a plurality of pins; the logic judgment circuit can judge whether at least one of the pins has short circuit, wherein the voltage value of the pin with the short circuit is larger than a preset voltage value; and the microcontroller is used for transmitting information of the pin with the short circuit to the display screen when one of the pins has the short circuit, and the display screen displays the information of the pin with the short circuit.

Description

technical field [0001] The invention relates to a short-circuit detection device, in particular to a short-circuit detection device for detecting MP3 players and transmission lines. Background technique [0002] Along with the rapid development of science and technology, consumer electronic products are constantly being introduced, especially MP3 players (MP3 Players) have been favored by consumers. Driven by global consumer electronics manufacturers, MP3 players can not only be used as MP3 players, but can also be integrated into other consumer electronics products, such as mobile phones and personal digital assistants (PDAs). Industry players related to consumer electronics are also actively conceiving next-generation MP3 player products to meet the needs of consumers. [0003] However, in the manufacturing and production process of MP3 players, due to the huge amount of production operations on the production line, it often happens that the MP3 player burns out due to a ...
