What are the characteristics of Waterproof Plug Connectors

The waterproof cord connector is called high-efficiency and energy-saving power supply. It represents the development direction of stable power supply. It has become a combination product of stable power supply. In the case of high-frequency switching, the link components inside the waterproofconnector consume energy. Very low, power service can reach 70-90%, almost double that of linear power plans The disadvantage of waterproof cord plugs is that the linear power regulator functions well, it can regulate the voltage rate, regulate the load, and the output noise and ripple control are large , and the electromagnetic interference of other electronic structures is simple, and the necessary response speed passes the processing.

Just plugging in the waterproof control program can be messy and noisier than a linear power supply, but an important advantage is that a waterproof connector has less functionality from the size and weight of the power supply function. There are more power supplies, which are made by the power supplies under similar conditions, which greatly reduces the volume ratio of the output power of the linear power supply, and also greatly reduces the capital. In this way, we do not know the pin connections of the bracket, so it is easy to save failure . In other words, my measurements are always biased and ultimately fail to suppress the drawn PCB connectors.

I think that's one of the differences between China and the rest of the world. Not only on the chip, but also on these details, we're not doing well. Generally speaking, earphones come with three-stage connector. The diameters of the plugs are usually 3.5mm and 2.5mm. Different diameter plugs correspond to earphone sockets with different diameter holes. So, from a system reliability standpoint, "Male" and "Female" should correspond, and pin and pin 4 should be grounded. In this case, when no headphones are plugged in, put the channel input on ground and the system input at 0.
