Abstract
A USB connection line with a status display function comprises a connection line, a USB input plug and a USB output plug, wherein the USB input plug and the USB output plug are respectively located on two ends of the connection line. The USB connection line is characterized in that the connection line further comprises a branching block which is internally provided with a voltage detecting unit, a switching unit, a first LED and a second LED; the voltage detection unit includes two input ends which are respectively connected to a VCC line and a GND line, and the voltage detection unit is connected to an input end of the switching unit; the first LED is bridged on the VCC line and the GND line after being connected in series with the switching unit; and the second LED is connected between the VCC line and the GND line after being connected in series with a current limiting resistor R1. The USB connection line with a status display function is convenient for people to judge a fault in USB connection.
Description
Technical field
The utility model relates to the USB tie that a kind of carrier state shows, it belongs to USB tie class.
Background technology
USB interface is the standard interface of computing equipment, multiplex connecting in computer equipment and external equipment, at the USB of prior art tie, comprise tie and two USB plug that lay respectively at the tie two ends, such USB tie is tape light not generally, whether two computer equipment that connect by the USB tie positive connection, people must be clear by the display screen ability of checking the computer equipment that connects by this USB tie, when particularly failing correctly to connect, be confused about owing to physical connection bad reason or other reason in a lot of situations, be not very good investigation in many situations, obviously prior art has further improved necessity.
Summary of the invention
The purpose of this utility model is to provide a kind of USB tie of carrier state demonstration, the problem that exists to overcome prior art.
The USB tie that a kind of carrier state of the present utility model shows, comprise tie and a USB input plug and a USB output plug of laying respectively at the tie two ends, include VCC in described USB input plug and the described USB output plug, GND, DATA+, the DATA-terminal, and each described terminal is respectively by the VCC line in the tie, the GND line, DATA+ line and DATA-line same polarity are corresponding to be connected, it is characterized in that also comprising on the described tie tap piece, be provided with voltage detection unit in the described tap piece, switch element, the one LED light-emitting diode and the 2nd LED light-emitting diode, described voltage detection unit comprises two inputs, described two inputs are connected in respectively on VCC line and the GND line, described voltage detection unit is connected to the input of switch element simultaneously, a described LED light-emitting diode be connected across on VCC line and the GND line after switch element is connected, be linked between VCC line and GND line behind described the 2nd LED light-emitting diode serial connection current-limiting resistance R1.
The USB tie that this a kind of carrier state of the present utility model shows, good the 2nd LED light-emitting diode of the physical connection of USB input plug and the arbitrary end of USB output plug and computer equipment USB socket will be luminous, thereby can point out the physical connection of people USB input plug and USB output plug and computer equipment whether good, described voltage detection unit then detects the voltage between lines of VCC line and GND line, and this voltage signal is outputed to the control end of switch element, when this voltage signal is lower than setting, described switch element is connected, the one LED lumination of light emitting diode, during an obvious LED lumination of light emitting diode, the voltage between lines that then shows VCC line and GND line is not enough, if the computer equipment that this moment, the USB tie connected can not normally connect, then obviously be that reason owing to the power supply aspect causes, if a LED light-emitting diode is not luminous, and the computer equipment that the USB tie connects can not normally connect, then show the reason that might relate to the driving aspect or wherein the usb circuit of at least one computer equipment have fault, obviously the USB tie of this carrier state demonstration of the present utility model is conducive to the failure cause that people judge that USB connects, and obviously the purpose of this utility model is achieved.
