In one embodiment of the utility model, the elastic arms 4 are arranged between the contact arms, so that the fisheye connection terminal can realize larger supporting force, thereby providing enough plugging force for the fisheye connection terminal, preventing the fisheye connection terminal from loosening under severe working conditions, and finally providing reliable contact resistance, thereby realizing reliable signal connection contact function.
In this embodiment, the elastic arm 4 is provided in an S-shaped structure in consideration of the fact that the contact force is insufficient to cause excessive contact resistance and release failure of the fisheye connection terminal, and the elastic arm 4 is connected to the edges of the left contact arm 2 and the right contact arm 3. The type of the elastic arm 4 may be various types known to those skilled in the art. In order to achieve the excellent insertion and extraction force, as shown in fig. 2, fig. 2 is a cross-sectional view of an elastic arm having an S-shaped elastic arm fisheye connection terminal according to an embodiment of the present utility model, two TYPEs of S-shaped structures are provided in the middle of the elastic arm 4, TYPE1 and TYPE2, respectively. Wherein, the upper and lower points of the elastic arm 4 with TYPE1 being S-shaped are respectively on the same horizontal plane with the left contact arm 2 and the right contact arm 3; the upper and lower points of the elastic arm 4 of TYPE2 are not on the same horizontal plane with the left contact arm 2 and the right contact arm 3, respectively. In the inserting process, the elastic arm 4 presents an S-shaped supporting force in the fish-eye connecting terminal, so that the damage of the PCB 6 caused by overlarge supporting force is avoided, and the service life of the PCB 6 is prolonged.

In this embodiment, a number of parameters known to those skilled in the art may be used for the length of the resilient arm 4. However, the height of the elastic arm 4 is adjusted according to the actual requirement of the elastic force, so that the length of the elastic arm 4 is longer than that of the contact arm. The ratio of the length H of the resilient arm 4 to the thickness T of the contact arm has a value H/T in the range of 1.5 to 2. The requirement of no-contact force is adjusted by adjusting the length H of the elastic arm 4 and the thickness L of the elastic arm 4, so that the requirement of limitation of the thickness of the product material is effectively solved.
