Plug classification small introduction

In everyday life we ​​use a variety of plugs, and now let's take a look at different categories.

According to the function can be divided into:

Headphone plug, dc plug, audio plug, usb plug, video plug, microphone plug, charger plug, mobile phone plug and so on. International appliances are divided into three categories:

One category: Electrical appliances refer to appliances that have only one layer of insulation. Such appliances must be equipped with a leakage protector and ground protection (that is, a three-pin plug). Such as air conditioning, machine tools, motors and so on.

Category II: There are double insulation measures for electrical appliances. If you want to add a leakage protector, you may not need to protect the ground (that is, you can use a two-pin plug). Such as: TV, fans, lamps, induction cookers, electric ceramic stoves and so on.

Three types: Electrical appliances are appliances that use safe voltage, typically 12-36V appliances such as air conditioners and water heaters.

Classified by safety certification:

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

Divided by structure:

Split plugs, sockets and connectors. Plugs and sockets are generally divided into two pole plugs and two poles with grounding plugs.

The current passes, so tell everyone here that if any electrical appliance is not used, it must be unplugged to save electricity.

For power products, there are usually four terms:

1, plug (plug). Refers to the portion of the plug that is connected to the power cord and has a male plug. The full name should be the plug connector. For two-legged flat plugs, English is sometimes spelled duckhead (duckhead, which is taken to mean its image).

2, connector (connector). Refers to the part that is connected to the power cord and has female sockets.

3, appliance input socket (inlet). Its state is similar to that of 1, but it is attached to a fixed body such as an electrical appliance and is not wired, including being mounted on a socket body.

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

We often confuse ourselves with 2 and 3 of these four words. We often call plugs with plugs, and outlets with holes are called outlets, but they are actually different.
