What are the classifications of power cord plugs?

Power cord is the most widely used in electrical appliances. Basically, electrical appliances need a power cord to be energized. However, many people think that power lines are needed wherever electricity is used, but they are not. Wires with plugs are called power cords. There are also many kinds of plugs. Let's look at the classification of power cord plugs!

What are the classifications of power cord plugs?

Power plugs can be roughly divided into conversion power plugs, injection power plugs and assembly power plugs.

Switching power plug: the standard of power plug in each country is different. For example, the power plug in China can't be used in the United States, and a conversion plug is needed to complete the conversion. This requires replacing the power plug. Modifying the power plug is to modify one GB plug into another GB plug.

Injection-molded power plug: Injection-molded power plug means that the plug and wire are pressed together by high temperature and high pressure, and once molded, they cannot be assembled or disassembled. This power plug has obvious characteristics and is stable and safe. More than 80% universal power plugs on the market are of this kind.

Assembling the power plug: Assembling the plug means that the power cord and the plug are fixed together with screws, but they can be disassembled during use, thus ensuring the flexibility of the power plug. For example, a large part of the British market is using this assembled power plug.

Power plugs can generally be divided into 2-core power plugs, 3-core power plugs and multi-core power plugs.

2-core power plug: As the name implies, a 2-core power plug has two blades or two pins, and the specific blades or pins are different in each country. For example, China has two blades and Europe has two round needles.

3-core power plug: As the name implies, 3-core power plug has 3 pieces or 3 pins or 2 pieces or 2 pins plus a grounding hole. This structure is more complicated than a 2-core power plug, and the standard requirements of pin size and diameter are very high. The length and spacing of pins are all factors to be considered.

Multi-core power plug: This kind of multi-core power plug is more complicated. What kind of 4-core power plug and 5-core power plug should be considered according to the requirements of customers, and what equipment should be used according to the actual situation.

At present, there are various power cord plugs on the market, and many people don't know how to find what we want among so many power cord plugs. The classification of power cord plugs introduced in the above small series is hoped to help you understand the power cord plugs.
