Hereinafter, specific embodiments of the electrical connector terminal 1 of the present invention will be described in detail with reference to FIGS. 1 to 3 . The electrical connector terminal 1 of the present utility model is used to electrically connect external electronic components (such as chip modules, not shown) to circuit boards (not shown, but can also be other electronic components), which includes metal parts and surrounding metal parts The outer elastic member, the metal member includes a first conductive terminal 10 and a second conductive terminal 11 electrically connected to the first conductive terminal 10, the elastic member in this embodiment is a spring connecting the first and second conductive terminals 10, 11 12.

The first conductive terminal 10 includes a pressing portion 101, a first conducting portion 102 extending from one end of the pressing portion 101 and electrically connected to an external electronic component, and a second conductive terminal 11 extending from the other end of the pressing portion 101 toward the second conductive terminal 11. Extended contact arm 103 . Wherein the pressing portion 101 is a rectangular plate-like structure, which is wider than the first conducting portion 102 and the contact arm 103 . The contact arm 103 is flat, and its width is smaller than the diameter of the inner circle of the spring 12 . A pair of limiting blocks 1032 protrude outward from the two side walls 1031 of the contact arm 103 , and each pair of limiting blocks 1032 is spaced apart to form a limiting opening 1033 .

The second conductive terminal 11 is provided with a base portion 111, wherein one end of the base portion 111 is extended to form a second conducting portion 112 that can be electrically connected to external electronic components, and the other end is extended to form a pair of contact arms 103 that can elastically support the above-mentioned contact arm 103. The elastic arms 113 are formed by extending symmetrically from the base portion 111 , and the free ends of the elastic arms 113 are provided with convex point-shaped clamping portions 1131 .
