It is suitable for some circuit connection scenarios that require frequent disassembly, and has the characteristics of simplicity, reliability, and easy disassembly. In electronic devices, fisheye pins are often used to connect power lines, signal lines, audio lines and other connecting lines. For example, in audio amplifiers, fisheye pins are often used to connect speaker lines, making it convenient for users to replace or repair speakers when needed. In addition, fisheye pins are also commonly used to test circuit boards. When testing circuit boards, the tester is usually connected to the fisheye pins to avoid interference from other components on the circuit board.

The fisheye portion includes elastic arms formed on two opposing side surfaces of the plug-in portion. The elastic arms protrude outward from the side surfaces of the plug-in portion, and a cavity is formed between the two elastic arms, which is recessed into the front surface of the plug-in portion.
