Technical Field

[0001] The utility model relates to the technical field of electronic connectors, in particular to a high-stable flatness terminal. Background Art

[0002] An electronic connector is a physical interface that connects two or more electrical and electronic devices. It usually consists of a male plastic shell and a female plastic shell. The connector contains terminals. Connector is a general term. Common connectors usually include two major parts: a plastic shell and a terminal. After a conventional terminal is inserted into place, the terminal surface and the plastic surface are stopped, and there is no upper or lower limit. There is a slight floating, which affects the size of the terminal solder foot protruding from the plastic surface. The size of the terminal protruding from the plastic surface is small. When the mating parts are mated at the upper and lower limits, the terminal is lower than the plastic surface, which is prone to poor tinning and affects the normal use of the terminal.
