What are the types of plugs and sockets

Power cords are the most widely used in electrical appliances. Basically, electrical appliances require power cords to power on. But many people think that a power cord is needed wherever electricity is used. In fact, it is not. The cord with a plug is called a power cord. There are also many types of plugs, let's take a look at the types of power plugs!

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

Converting power plugs: The power plug standards of each country are different. For example, the power plugs in China cannot be used when they arrive in the United States. You must need a conversion plug to complete the conversion. This requires changing the power plug. Converting the power plug is to convert a national standard plug into another national standard power plug.

Injection molding power plug: The injection molding plug is the plug and the wire that are pressed together by high temperature and high pressure. Once formed, they cannot be assembled or disassembled. Such a power plug has obvious characteristics, stability and safety. More than 80% of the power plugs generally circulating on the market are such power plugs.

Assembly of the power plug: The assembly of the plug means that the power cord and the plug are fixed together by screws, etc., but they can be assembled and disassembled during use, which ensures the flexibility of the power plug. For example, a large proportion of the UK market is using this type of assembled power plug.

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

2-pin power plug: The 2-pin power plug, as the name suggests, has two blades or two pins. The specific blades or pins are different in each country. For example, China has two blades, and Europe has two blades. Two round needles.

3-pin power plug: The 3-pin power plug, as the name suggests, has 3 blades or 3 pins or two blades or two pins plus a grounding hole. Such a structure is more complicated than a 2-pin power plug. The size and diameter of the pins have great requirements, and the length and the distance between the pins are all factors to be considered.

Multi-core power plug: This multi-core power plug is more complicated. What kind of 4-pin power plug, 5-pin power plug, etc., according to the customer's requirements, which specific equipment to use should be considered according to the actual situation.

Attached design, it can be used repeatedly after washing with water after falling off.
