No, the plug smokes because the wires heat up due to poor contact between the terminals or sockets in the socket. Since the insulation layer of the wires is made of flame-retardant materials, they usually burn and smoke. You must replace.
The connector (Connector) of general electronic products and the pin (Pin) of electrical supplies are called plugs. Household AC power plugs and sockets have a rod-shaped or copper plate-shaped protruding male connector that physically inserts into a female connector-type power socket with a slot or recess.
Size is an important technical requirement related to whether plugs, sockets and converters can be used safely and meet universal interchangeability requirements to avoid misinsertion.
Substandard dimensions may affect the user's use or cause hidden dangers such as poor contact and misinsertion, which may cause damage to the equipment at best, or cause fires and electric shock accidents at worst.
