What are the classifications of plugs

According to the function can be divided into:

Headphone plugs, dc plugs, audio plugs, usb plugs, video plugs, microphone plugs, charger plugs, mobile phone plugs, etc. Internationally, household appliances are divided into three categories:

Class 1: Electrical appliances refer to electrical appliances with only one layer of insulation measures. Such electrical appliances must be equipped with leakage protectors and grounding protection (that is, three-pin plugs). Such as air conditioners, machine tools, motors, etc.

Category 2: Electrical appliances have double-layer insulation measures, and a leakage protector should be added, and grounding protection is not required (that is, a two-pin plug can be used). Such as: TV, electric fan, table lamp, induction cooker, electric pottery cooker, etc.

Three categories: electrical appliances are electrical appliances that use safe voltage, generally 12-36V electrical appliances, such as air conditioners, water heaters, etc.

UL/CUL, VDE, CCC, T-MARK, SAA, BSI, PSB, SABS, PSE, SNI, UC, etc.

Sub-plugs, sockets and connectors. Plugs and sockets are generally divided into two-pole plugs and two-pole grounding plugs.

The current passes through, so I would like to tell you here that as long as any electrical appliance is not in use, it must be unplugged to save electricity.

For power products, there are usually four nouns:

1. A plug. Refers to the part that is connected to the power cord and has a male plug. The full name should be called a plug connector. For two-pin flat plugs, English is sometimes spelled duckhead (duck head, whichever is the image).

2. Connector. Refers to the part that is connected to the power cord and has a female socket socket.

3. Appliance input socket (inlet). Its state is similar to 1, but it is installed on a fixed body such as an electrical appliance and is not connected, including the one installed on the socket body.

4, socket (socket). Its status is similar to 2, but the installation location is the same as 3. The full name should be called Appliance Socket.
