In the conventional fisheye terminal, the upper hole area of the fisheye 40 is fully disposed in the elastic part 20, which causes two problems. Firstly, the overall height of the fish-eye terminal is higher, which is not beneficial to miniaturization design; secondly, the junction of the shoulder 10 and the elastic portion 20 is narrowed, and the elastic supporting performance of the elastic portion 20 and the connection stability with the shoulder 10 are deteriorated.
Therefore, in order to solve the above-mentioned problems, it is necessary to design a fish-eye terminal.
