Problems solved by technology
The previous chargers, such as those used to charge notebook computers, need to see the computer screen when charging to know whether the charging is good and whether the contact is good. This charging method is not only very troublesome but also wastes power and is not environmentally friendly. Require

The invention discloses a charger connecting line with an indicating device. The charger connecting line comprises a connecting end, a plug, an electronic jumper wire and a light-guiding ring, wherein the connecting end is connected to a printed circuit board (PCB) inside the charger; the plug is connected with the connecting end through a wire and the plug also comprises a PCB, on which a resistor and a light-emitting diode (LED) are welded; the resistor and the LED are connected in series; the electronic jumper wire is used for connecting the PCB and the plug so as to supply power to the LED on the PCB; the light-guiding ring is positioned on the surface of the plug and is made of transparent material; and when the LED is connected to a power source, the light-guiding ring can be lighted. Therefore, by the light-guiding ring, a user can judge whether the charger is in a charging state from a long distance and judge whether the plug is in full contact with the socket, the charger connecting line is convenient to use and electric energy is saved.
Description
technical field [0001] The invention relates to a charger connection line with an indicating device, in particular to a charger connection line which allows users to judge whether their own charger is in a charging state through the indication device at a distance. Background technique [0002] A charger that is often used in daily life is a device that converts alternating current into low-voltage direct current. The charger is a conversion device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current. Chargers are widely used in various fields, especially in the field of life, they are widely used in common electrical appliances such as notebook computers, mobile phones, and cameras. With the continuous development of social economy, it has promoted the growth of market sales in the electrical appliance industry. At the same time, the implementation of events and policies such as 3G commercia...
