Abstract

The invention discloses an electrical connector, which includes: an insulating body having transverse and longitudinal directions; a plurality of first terminals held in the insulating body, each first terminal including a first contact portion, and a a first welding part for welding the surface of the circuit board, and a first connection part for longitudinally connecting the first contact part and the first welding part; and a plurality of second terminals held in the insulating body, Each second terminal includes a second contact portion, a second soldering portion for soldering to the surface of the circuit board, and a second connection longitudinally connecting the second contact portion and the second soldering portion. department. In the present invention, the first welding portions of the plurality of first terminals and the second welding portions of the plurality of second terminals are arranged in two different rows instead of neatly arranged in one row. Therefore, the first welding portion is enlarged. and the second welding portion, thereby reducing mutual crosstalk between the first terminal and the second terminal.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector capable of transmitting high-speed signals. Background technique [0002] Electrical connectors use conductive terminals to provide signal connections between electronic devices. Usually, the spacing between the conductive terminals is very close, so that crosstalk occurs between adjacent conductive terminals, thereby destroying the integrity of the signal. [0003] Universal Serial Bus (USB) is a universal serial bus standard protocol. The standard association has now begun to upgrade the standard from the now popular USB2.0 standard protocol to USB3.0 standard protocol, and the signal transmission speed has changed from the original 480Mbit The theoretical upper limit of / s is increased by 10 times to 5Gbit / s. Correspondingly, this poses a greater challenge to the design of USB connectors, especially how to reduce the crosstalk between adjacent signal conductiv...
