Electric connector

Abstract

The invention discloses an electric connector, which comprises an insulation main body, a plurality of first terminals and a plurality of second terminals, wherein the insulation main body has a transverse direction and a longitudinal direction; the plurality of first terminals are held in the insulation main body, and each first terminal comprises a first contact part, a first welding part and a first connecting part, wherein the first welding part is used for welding with the surface of a circuit board, and the first connecting part is longitudinally connected with the first contact part and the first welding part; and the plurality of second terminals are held in the insulation main body, and each second terminal comprises a second contact part, a second welding part and a second connecting part, wherein the second welding part is used for welding with the surface of the circuit board, and the second connecting part is longitudinally connected with the second contact part and the second welding part. In the invention, the first welding parts of the plurality of first terminals and the second welding parts of the plurality of second terminals are arrayed to form two different lines rather than regularly arrayed to form one line, and therefore a space between the first welding parts and the second welding parts is increased, and mutual crosstalk between the first terminals and the second terminals is consequently reduced.

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...
