In everyday life, power cord plugs are a common household item with a wide range of applications and extensive popularity. They are predominantly used to connect electrical appliances to power sources, ensuring their normal operation. However, different appliances require different types of power cord plugs, necessitating a diverse range to better meet market demands. This also facilitates the smooth operation of various appliances, preventing damage due to incompatible power cord plugs.

Two-core power cable plug, as the name implies, refers to a plug with two pins or prongs. The specific type of pin or prong varies by national standard; for instance, in China, it is two flat blades, while in Europe, it is two round pins.

Three-prong power plug, as the name implies, is a plug with three prongs or pins, or two prongs or pins with a grounding hole. This structure is more complex than a two-prong power plug, with strict standards for the size and diameter of the pins, as well as the length and spacing between the pins.

Multi-core power cable plugs are more complex. Four-core and five-core power plugs can be customized according to the specific requirements of the customer. The application of these plugs on any particular equipment should be considered based on the actual situation and used accordingly.
