The first, second, third, and fourth opening portions 315, 325, 335, and 345 have a first, second, and First, second, third, and fourth openings 316, 326, 336, 346 of the third and fourth body portions 311, 321, 331, 341. The first opening 316 of the first terminal 31 extends away from the first solid portion 314 toward the first direction A, even if the first opening 316 is biased toward the first direction A relative to the entire first body portion 311; The second opening 326 on the second terminal 32 extends away from the second solid portion 324 in a second direction B opposite to the first direction, even if the second opening 326 is biased relative to the entire second body portion 321 The second direction B is such that the first opening 316 and the second opening 326 are staggered. Therefore, in the electrical connector 100, since the first terminal 31 and the second terminal 32 are disposed in the same row, the first opening 316 of the adjacent first terminal 31 faces the second solid portion 324 of the second terminal 32. The second opening 326 of the second terminal 32 faces the first solid portion 314 of the first terminal 31, such that the area of the overlapping portion of the metal portions of the first terminal 31 and the second terminal 32 is relatively reduced, thereby Reducing the positive capacitance of the adjacent first and second terminals 31, 32 to reduce the capacitance (the capacitance is proportional to the facing area), thereby increasing the characteristic impedance between the terminals to satisfy the high frequency signal transmission The need to enable high-frequency signals to be transmitted stably. At the same time, the reduction in the area can also reduce the crosstalk of signals transmitted by adjacent terminals during signal transmission.

Referring to the fourth figure, the third terminal 33 and the fourth terminal 34 are alternately arranged in another row. Like the first terminal 31, the third opening 336 of the third terminal 33 faces away from the third solid portion 334. The first direction A extends such that the third opening 336 is biased toward the first direction A relative to the entire third body portion 331; and like the second terminal 32, the fourth opening 346 of the fourth terminal 34 faces away from the fourth body portion The 344 extends in the second direction B, so that the fourth opening 346 is biased toward the second direction B relative to the entire fourth body portion 341, so that the third terminal 33 is adjacent to the first terminal 31 and the second terminal 32. Fourth end The metal portion of the sub-34 is relatively reduced in area of the coincident portion, and the characteristic impedance between the terminals can also be increased to meet the needs of high-frequency signal transmission.

Referring to the fourth figure, the first terminal 31 and the third terminal 33 are connected to the first tape 35, and the second terminal 32 and the fourth terminal 34 are connected to the second tape 36. At the same time, since the first terminal 31 and the fourth terminal 34 have the same structure, the second terminal 32 and the third terminal 33 have the same structure, so that the first terminal 31 and the third terminal 33 arranged in parallel form the first terminal group 37, and juxtaposed The second terminal 32 and the fourth terminal 34 constitute the second terminal group 38, and the overall structure of the first terminal group 37 is the same as that of the second terminal group 38. In the electrical connector 100, the second terminal group 38 can be regarded as Rotating the first terminal group 37 by 180 degrees, so that the first and third openings 316, 336 of the first and third terminals 31, 34 and the second and fourth terminals 32, 34 are second and The four openings 326, 346 are offset in opposite directions. In this way, the above structure can be realized by designing only one set of terminal groups, thereby reducing the time for designing and manufacturing the terminal mold and reducing the manufacturing cost.

Referring to the second figure, the metal plate 40 is disposed between the two rows of terminals 30 to separate the two rows of terminals 30 to avoid signal crosstalk between the terminals 30 juxtaposed in the two rows of terminals 30.
