[0027] The spring terminal 20 can be repeatedly compressed and bounced and is arranged on the fixing frame 10. The multiple spring terminals 20 are arranged in two rows with a staggered structure. The spring terminal 20 includes a contact portion 21 and a welding foot portion 22. The contact portion 21 and the welding foot portion 22 always exceed the top and bottom ends of the fixing frame 10 respectively. The contact portions 21 and the welding foot portions 22 of the spring terminals 20 in different rows are arranged close to each other.

[0028] By providing two rows of spring-type terminals 20 and staggering the structure, the spacing between the two rows of spring-type terminals 20 is reduced, thereby reducing the volume and occupied space of the connector; Figure 6 As shown, the spring terminal 20 has a height H1 when no external force is applied, and the contact portion 21 is compressed during operation, and the working height is H2.

[0029] Specifically, the spring terminal 20 is C-shaped, and the spring terminal 20 extends out of the soldering foot portion 22 at the bottom end of the fixing frame 10 to be soldered to the PCB board.
