New description: [New technical field] The present invention is a type of electrical connector, especially an electrical connection for transmitting high frequency signals. [Prior Art] General control ^^4^^ The electrical connector for transmitting high-frequency signals is increasingly the stability of the high-frequency signal during transmission. The advantage is that the wiring is very close to the differential soil: ΐί To: small EMI emission, so the transmission timing can be refined The early signal of the tree two rules can also be used at a higher speed. Due to the difference between the two: the signal line (the signal is equivalent and the opposite), the value between the signals is 'the line' = the best effort should be used in the rhyme differential line pair. The king's consistent wiring length and impedance, and try to close the two. Please refer to the Republic of China Patent Bulletin Issue No. 78 Body 2: Number Connector: The electrical connector includes an insulating body and is housed in insulation. These terminals are electrically connected to the mating connector. The contact ^, the soldering portion of the female clothing on the circuit board, and the tandem portion at the contact portion are arranged in two rows. Because of the setting of such a connector, each pair transmits a differential signal when transmitting the differential signal. The same end, the same will cause the difference signal to be transmitted on the terminal at different times, because
