[0035] See also Figure 1-8 As shown, an electrical connector 100 in accordance with the present invention is a high-speed and high-frequency electrical connector 100 for transmitting high-speed signals. The electrical connector 100 can be mounted on an external circuit board (not shown) and used to cooperate with a docking electrical connector 100. The electrical connector 100 includes an insulating housing 10 and a terminal module 20 accommodated in the insulating housing 10.

[0036] The insulating housing 10 includes an upper wall 131, a lower wall 132, and a pair of side walls 133 connecting the upper wall 131 and the lower wall 132. The front end of the insulating housing 10 is recessed to form the docking groove 101. The docking groove 101 is used for plugging the docking plate of the docking connector. The rear end of the insulating housing 10 is provided with an assembly groove 102 connected to the docking groove 101 front and back. The insulating housing 10 also holds a pair of mounting metal parts 30. The mounting metal parts 30 can be welded to the external circuit board.

[0037] The terminal module 20 includes a first terminal module 21 and a second terminal module 22 located at the lower side of the first terminal module 21 and matched with the first terminal module 21. The first terminal module 21 includes a first insulator 201 and a first row of conductive terminals 210 held in the first insulator 201 and arranged in a transverse direction. The second terminal module 22 includes a second insulator 202 and a second row of conductive terminals 220 held in the second insulator 202 and arranged in a transverse direction. The first row of conductive terminals 210 is integrally formed with the first insulator 201, and the second row of conductive terminals 220 is integrally formed with the second insulator 202.

[0038] Each of the first row of conductive terminals 210 includes a fixing portion 211 fixed to the first insulator 201, an elastic arm 212 extending forward from one end of the fixing portion 211 out of the first insulator 201, and a tail portion 213 extending from the other end of the fixing portion 211 out of the first insulator 201. The front end of the elastic arm 212 is further provided with a contact portion 214 extending forward to cooperate with the docking connector. The first row of conductive terminals 210 includes a plurality of first grounding terminals 216 and a plurality of pairs of first signal terminals 217. Each pair of first signal terminals 217 is located between adjacent first grounding terminals 216.

[0039] Specifically, in the present invention, the connection bridge 2120 is integrally stamped with the first ground terminal 216. The connection bridge 2120 and the elastic arm 212 of the first ground terminal 216 are located in the same plane. The two first ground terminals 216 on both sides of a pair of first signal terminals 217 are connected by the connection bridge 2120, and the first ground terminals 216 on both sides of different pairs of first signal terminals 217 are not provided with a connection bridge. That is, the connection bridge 2120 is not provided between the first ground terminals 216 on both sides of another pair of signal terminals 217 adjacent to the pair of first signal terminals 217. By connecting the first ground terminals 216 on both sides of a pair of first signal terminals 217 using the connection bridge 2120, the generation of resonance can be reduced, and the impedance of the elastic wall area can be adjusted, thereby effectively improving the high-frequency performance of the electrical connector 100.

The connecting bridge 2120 and the first horizontal portion 2011 are located in the same plane. The fixed portion 211, the contact portion 214 and the tail portion 213 of the first grounding terminal 216 and the first signal terminal 217 in the first row of conductive terminals 210 are aligned with each other in the lateral direction.

[0041] The configuration of the second row of conductive terminals 220 is substantially the same as that of the first row of conductive terminals 210. Each of the second row of conductive terminals 220 includes a fixing portion 221 fixed to the second insulator 202, an elastic arm 222 extending forward from the fixing portion 221 out of the second insulator 202, and a tail portion 223 extending from the other end of the fixing portion 221 out of the second insulator 202. The front end of the elastic arm 222 is further provided with a contact portion 224 extending forward. The second row of conductive terminals 220 includes a plurality of second grounding terminals 226 and a plurality of pairs of second signal terminals 227. Each pair of second signal terminals 227 is located between adjacent second grounding terminals 226. The elastic arms 222 of the second grounding terminals 226 are connected together by a connecting bridge 2220. The elastic arms 222 of the second signal terminals 227 are provided with a avoiding portion 2221 avoiding the connecting bridge 2220. The avoiding portion 2221 is formed by bending inward.

[0042] The fixing portion 221, the contact portion 224 and the tail portion 223 of the second grounding terminal 226 and the second signal terminal 227 are aligned with each other as a whole. The connecting bridge 2220 and the elastic arm 222 of the second grounding terminal 226 are arranged in the same plane. A T-shaped protrusion 215 is protruded downward on the lower surface of the first insulator 201, and a groove 225 is formed on the upper surface of the second insulator 202, and the groove 225 matches the protrusion 215. The first insulator 201 and the second insulator 202 are assembled and clamped in the front-to-back direction, and the second insulator 202 abuts against the first vertical portion 2012 backward. The first insulator 201 and the second insulator 202 are assembled and fixed to each other, and then assembled into the insulating housing 10 from the assembly groove 102.
