What are the characteristics of waterproof plugs?

　　The waterproof plug is called high efficiency, environmentally friendly and energy saving switching power supply. It implies the development prospect of smooth switching power supply. It has become a component of smooth switching power supply. Under the condition of high-frequency switching, the connecting parts inside the waterproof plug will consume kinetic energy. Very low, switching power supply service items can do 70-90%, basically two times of the linear regulated power supply program. The defects of the waterproof plug is the linear regulated power supply controller role is excellent, it can adjust the working voltage speed, adjust the load, the output noise and harmonic distortion manipulation is very large, and other electronic structure of the interference signal easy, and the necessary response time according to the waterproof plug manufacturers to solve. Compared with the linear regulated power supply, only inserted into the moisture management program will be more than linear regulated power supply clutter and noise, but a key advantage is that the waterproof plug from the switching power supply role of the specifications and the net weight seems to have a lesser role. Switching power supply a large number of, it is manufactured by the waterproof plug manufacturer with switching power supply in similar conditions, substantially reducing the volume ratio of linear regulated power supply power, but also substantially reduce the assets that way, people are not clear about the support frame pin-plug coupling, and therefore very easy to store the common faults. That is to say, my measurements have been inaccurate, and finally could not suppress the drawing of the PCB RF connector.　　Waterproof plug manufacturers feel that it is one of the differences between China and the rest of the world. Not only in the integrated ic, but also in this key point, waterproof plug manufacturers are not doing well. Generally speaking, cell phone headset contains three levels of power plug. The diameter of the power plug is generally 3.5 mm and 2.5 mm. Power plugs of different diameters are matched to headphone sockets with different diameter holes. Thus, from the point of view of reliability indicators, the "male" and "female" should match, and the foot and foot 4 should be grounded. In this case, when the cell phone headset is not plugged in, please key the safe channel to the road and the system software to 0.
