[0038] See also Figure 1 As shown, it is an electrical connector 100 disclosed in the present invention, which is used to electrically connect a chip (not shown in the figure) to a circuit board (not shown in the figure) or to connect two circuit boards, including an insulating body 10 and a plurality of terminals 20. The insulating body 10 is provided with an upper surface 11, a lower surface 12 and terminal slots 13 penetrating the upper and lower surfaces 11 and 12, and the terminals 20 are arranged one by one in the corresponding terminal slots 13. This embodiment only schematically shows one of the terminals 20 of the electrical connector 100 and the terminal slot 13 accommodating the terminal 20. In an actual product, there are multiple terminals 20 arranged in a matrix.

[0039] Combination Figure 2-3 The terminal 20 is formed by stamping and bending a metal plate, and includes a base 200, an upper elastic portion 22, an upper contact portion 23 and an upper abutting portion 25 extending upward from the base 200 in sequence, and a lower elastic portion 24, a lower contact portion 26 and a lower abutting portion 27 extending downward from the base in sequence, the upper abutting portion 25 is bent downward from the upper contact portion 23, and the lower abutting portion 27 is bent upward from the lower contact portion 26. The base 200 has a left surface 201 and a right surface 202 opposite to each other, and the base 200 is provided with an upper support portion 203 and a lower support portion 204 protruding from its right surface 202. Figure 8 When the upper and lower contact parts 23 and 26 move toward the insulating body 10, the upper abutting part 25 abuts against the upper supporting part 203, and the lower abutting part 27 abuts against the lower supporting part 204. It should be particularly noted that the upper, lower, left and right in this embodiment are only used to facilitate the description of the connector and should not be understood as limiting the scope of the specification and claims of this application. Figure 4 The base 200 is provided with a groove 210 running through its left and right surfaces. The upper support portion 203 is formed by bending from the upper edge of the groove 210, and the upper support portion 203 is located directly below the upper abutment portion 25; the lower support portion 204 is formed by bending from the lower edge of the groove 210, and the lower support portion 204 is located directly below the lower abutment portion 27.

[0040] See also Figure 2 and Figure 4, viewed from a direction perpendicular to the left and right surfaces 201, 202 of the base 200, the upper and lower support portions 203, 204 are offset and staggered with each other along the width direction of the base 200 without overlap. The width of the upper contact portion 23 is greater than the width of the upper abutting portion 25, the width of the lower contact portion 26 is greater than the width of the lower abutting portion 27, and the upper and lower abutting portions 25, 27 extend downward from the outer edges of the upper and lower contact portions 23, 26 that are away from each other, that is, the upper and lower abutting portions 25, 27 are respectively close to one side edge of the upper and lower contact portions 23, 26 that are away from each other, and the outer edge of the upper abutting portion 25 is coplanar with the outer edge of the upper contact portion 23, and the outer edge of the lower abutting portion 27 is coplanar with the outer edge of the lower contact portion 26. The end of the upper abutting portion 25 is a spoon-shaped structure, and the end of the lower abutting portion 27 is also a spoon-shaped structure. Further combined Figure 5 In order to facilitate the upper and lower abutting portions 25 and 27 to contact the corresponding upper and lower supporting portions 203 and 204 respectively after being pressed, the width of the upper abutting portion 25 is smaller than the width of the upper supporting portion 203, and the width of the lower abutting portion 27 is smaller than the width of the lower supporting portion 204. In addition, in this embodiment, the width of the upper elastic portion 22 is larger than the upper contact portion 23, and the width of the lower elastic portion 24 is larger than the lower contact portion 26.

[0041] Combination Figure 3 , 7 and Figure 8 In order to increase the elasticity of the upper elastic part 22 and the lower elastic part 24, the upper elastic part 22 is provided with an upper opening 220 that passes through its left and right surfaces, and includes an upper vertical part 221 and an upper inclined part 222. The lower elastic part 24 is provided with a lower opening 240 that passes through its left and right surfaces, and includes a lower vertical part 241 and a lower inclined part 242. When the terminal is not compressed, the upper and lower vertical parts 221, 241 and the base 200 are located in the same vertical plane. The upper opening 220 spans the upper vertical part 221 and the upper inclined part 222, and the lower opening 240 spans the lower vertical part 241 and the lower inclined part 242. Therefore, when the terminal is compressed and deformed, the upper vertical part 221 and the upper inclined part 222 are compressed and deformed together, and at the same time, the lower vertical part 241 and the lower inclined part 242 are compressed and deformed together. The width of the base 200 is greater than the width of the upper and lower elastic parts 22, 24, and the width of the slot 210 is greater than the width of the upper and lower openings 220, 240. In addition, for the convenience of terminal installation, the lower elastic part 24 is provided with strip connecting parts 243 on both sides.

[0042] See also Figure 4-6In this embodiment, the upper elastic portion 22 and the lower elastic portion 24 of the terminal 20 are symmetrically arranged in the up-down direction, but the upper abutting portion 25 and the lower abutting portion 27 are staggered in the width direction of the terminal 20, and the upper support portion 203 and the lower support portion 204 are also staggered in the width direction of the terminal, and the upper and lower support portions 203 and 204 are bent from the upper and lower edges of the slot 210 and extend in the horizontal direction. In this way, after the upper elastic portion 22 and the lower elastic portion 24 of the terminal are pressed and deformed, the upper abutting portion 25 can easily abut against the upper support portion 203, and the lower abutting portion 27 can also easily abut against the lower support portion 204.
