[0043] See also Figure 1-2 5-8, which is an electrical connector 100 disclosed in the present invention, used to electrically connect a docking component (such as a chip module) to a circuit board or connect two circuit boards. The electrical connector 100 includes an insulator 10 and a plurality of terminals 20 arranged in a matrix. The insulator 10 is provided with an upper surface 11, a lower surface 12, and terminal slots 13 penetrating the upper surface 11 and the lower surface 12. The terminals 20 are arranged one by one in the corresponding terminal slots 13. It should be particularly noted that for this type of electrical connector 100, the number of terminals is relatively large, and there may be thousands of them. The present invention only schematically shows a terminal 20 and a terminal slot 13 for accommodating the terminal.

[0044] Combination Figure 3-4And 8-10, each of the terminals 20 includes two conductors, each of which includes a holding portion, an additional portion arranged opposite to the holding portion, a connecting portion connecting the holding portion and the additional portion, and an elastic arm extending from the additional portion. The terminal slot 13 includes a fixing slot 131 that passes through the upper and lower surfaces 11 and 12 and a receiving slot 132 that communicates with the corresponding fixing slot 131. The holding portion is fixed in the corresponding fixing slot 131, the connecting portion and the additional portion are located in the receiving slot 132, and the elastic arm extends out of the receiving slot 132 and is provided with a contact portion. The two conductors are respectively assembled from the upper and lower surfaces 11 and 12 and inserted into the terminal slot 13, and the connecting portions of the two conductors are pressed against each other up and down and contact. Each conductor also includes a lap portion extending vertically from the holding portion, the lap portion extending out of the corresponding fixing slot 131, and when the elastic arm is retracted into the receiving slot 132, the end of the elastic arm contacts the corresponding lap portion. Specifically, each terminal 20 includes an upper conductor 21 and a lower conductor 22, wherein the upper conductor 21 includes an upper holding portion 210 held in the terminal slot 13, an upper attachment portion 211 disposed face to face with the upper holding portion 210, an upper connection portion 213 connecting the upper holding portion 210 and the lower end of the upper attachment portion 211, and an upper elastic arm 214 extending upward from the upper attachment portion 211 to the upper surface 11, and the upper elastic arm 214 is provided with an upper contact portion 215 located above the upper surface 11. The lower conductor 22 includes a lower holding portion 220 held in the terminal slot 13, a lower attachment portion 221 disposed face to face with the lower holding portion 220, a lower connection portion 223 connecting the lower holding portion 220 and the lower attachment portion 221, and a lower elastic arm 224 extending downward from the lower attachment portion 221 to the lower surface, and the lower elastic arm 224 is provided with a lower contact portion 225 located below the lower surface 12. When the upper conductor 21 and the lower conductor 22 are installed in place in the terminal slot, the upper connecting portion 213 and the lower connecting portion 223 are in contact with each other in the up-and-down direction.

[0045] See also Figure 6-10 The upper conductor member 21 also includes an upper overlapping portion 216 extending upward from the upper retaining portion 210. After the upper elastic arm 214 moves downward, its end contacts the upper overlapping portion 216. The lower conductor member 22 includes a lower overlapping portion 226 extending downward from the lower retaining portion 220. After the lower elastic arm 224 moves upward, its end contacts the lower overlapping portion 226. In this embodiment, preferably, the upper overlapping portion 216 protrudes upward from the upper surface 11 of the insulator, and the lower overlapping portion 226 protrudes downward from the lower surface 12 of the insulator 10. The end of the upper contact portion 215 is bent inward to form an arc-shaped upper abutting portion, and the end of the lower contact portion 225 is also bent inward to form an arc-shaped lower abutting portion. After the upper and lower elastic arms 214 and 224 are pressed, the upper abutting portion contacts the upper overlapping portion 216, and the lower abutting portion contacts the lower overlapping portion 226. See FIG. Figure 2-4In order to ensure the elasticity of the upper elastic arm 214 and the lower elastic arm 224, the upper elastic arm 214 includes a first inclined portion 217 inclined upward and outward from the upper additional portion 211, a vertical portion 218 extending upward, a second inclined portion 219 inclined inward and upward, and the upper contact portion 215 in an inverted V shape. The lower elastic arm 224 includes a third inclined portion 227 inclined downward and outward from the lower additional portion 221, a vertical portion 228 extending downward, a fourth inclined portion 229 inclined inward and downward, and the lower contact portion 225 in a V shape. The upper elastic arm 214 includes a slot 2110 extending from the first inclined portion 217 to the second inclined portion 219, and the lower elastic arm 224 includes a slot 2210 extending from the third inclined portion 227 to the fourth inclined portion 229.

[0046] See also Figure 3-4 , 7 and 9-10, preferably, in this embodiment, the upper holding portion 210 and the upper overlapping portion 216 are located in the same vertical plane, and the vertical plane is arranged in parallel with the upper additional portion 211, and the upper connecting portion 213 extends horizontally and connects the upper holding portion 210 and the upper additional portion 211. The lower holding portion 220 and the lower overlapping portion 226 are located in the same vertical plane, and the vertical plane is arranged in parallel with the lower additional portion 221, and the lower connecting portion 223 extends horizontally and connects the lower holding portion 220 and the lower additional portion 221, and the upper conductor 21 and the lower conductor 22 are arranged symmetrically along the upper and lower directions. Figure 5-6 The insulator 10 also includes an upper retaining wall 17 extending upward from the upper surface 11 of the insulator 10 and located on the left and right sides of the upper elastic arm 214, and a lower retaining wall 14 extending downward from the lower surface 12 of the insulator 10 and located on the left and right sides of the lower elastic arm 224. The height of the upper retaining wall 17 extending upward is higher than the height of the vertical portion 218, and the lower retaining wall 14 extends downward beyond the lower end of the vertical portion 228.

[0047] See also Figure 2 , 7 and Fig.10In this embodiment, since the first inclined portion 217 extends upward and outwardly beyond the terminal slot 13, when the upper conductor 21 is installed into the terminal slot 13 from top to bottom and is installed in place, the first inclined portion 217 will abut against the upper end of the corresponding side wall of the corresponding terminal slot 13, which can effectively prevent the upper conductor 21 from being excessively installed downward into the terminal slot 13. Correspondingly, since the third inclined portion 227 extends downward and outwardly beyond the terminal slot 13, when the lower conductor 22 is installed into the terminal slot 13 from bottom to top and is installed in place, the third inclined portion 227 will abut against the lower end of the side wall of the corresponding terminal slot, which prevents the lower conductor 22 from being excessively installed upward into the terminal slot 13. In this way, the fixing groove 131 can be set as a slot that penetrates in the up-down direction, which is convenient for the processing and manufacturing of the insulator 10, and the installation of the upper conductor 21 and the lower conductor 22 of the terminal 20 will not be excessively installed because the fixing groove 131 penetrates in the up-down direction. In addition, in the present application, the holding portion, the overlapping portion and the additional portion of the two conductors of the terminal 20 are all arranged vertically and the connecting portion is arranged horizontally, so the processing and manufacturing of the terminal 20 is relatively convenient. When the upper and lower elastic arms 214 and 224 of the terminal 20 are pressed, the upper contact portion contacts the upper overlapping portion 216, the lower contact portion contacts the lower overlapping portion 226, and the upper connecting portion 213 contacts the lower connecting portion 223 in the upper and lower directions, so the terminal 20 has multiple contact points, and the terminal has better signal transmission performance.
