The electrical appliances that we commonly find on the day need to be connected to the power cord through a plug, and the electrical appliances can operate. What people usually see is the power plug, also called the power cord plug. Depending on the purpose of the power plug, the power cord plug can be used at 250V, 125V, and 36V, depending on the current, it can be used in 16A, 13A, 10A, 5A, and 2.5A.

There are many types of plugs, such as earphone plugs, mobile phone charger plugs that are most commonly used in mobile phones, audio-video plugs connected to computers, digital cameras, digital video cameras, etc. all use DC plugs. Huizhou Yuanyang Electronics Co., Ltd. is a comprehensive supporting manufacturer specializing in R&D, production, sales, and service; mainly producing DC plugs, headphone plugs, DC heads, DC sockets, and other products.
