Problems solved by technology

[0003] A commonly used technology for reducing crosstalk is to set ground terminals between adjacent signal terminals, such as an electrical connector disclosed in Chinese Invention Patent Publication No. 1937324A, which is used to transmit high-frequency digital signals , which includes an insulating body, a conductive terminal and a shielding shell covering the insulating body. The insulating body includes a base and a tongue protruding forward from the base. Each conductive terminal includes a contact portion arranged on the surface of the tongue and an extension All the welding parts are arranged in a row, and the conductive terminals include ground terminals and several pairs of differential signal terminals. However, there is only one ground connection between the welding parts of two adjacent pairs of differential signal terminals of the electrical connector. The welding part of the terminal makes the crosstalk between two adjacent pairs of differential signal terminals still high, which affects the signal transmission quality of the electrical connector

Abstract

The invention discloses an electric connector, comprising an insulating body and a conductive terminal arranged on the insulating body. The conductive terminals comprise a plurality of grounded terminals and a plurality of pairs of differential signal terminals, wherein each grounded terminal is provided with a first welding part extending out of the insulating body, each differential signal terminal is provided with a second welding part extending out of the insulating body, and the first, second and third welding parts are arranged into one row, and the first welding part of two grounded terminals is arranged between the second welding parts adjacent to the two pairs of differential signal terminals, thereby the shielding effect between the two adjacent pairs of differential signal terminals is increased, the crosstalk between the differential signal terminals is reduced, and the signal transmission quality of the electric connector is improved.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector with differential signal transmission. 【Background technique】 [0002] Electrical connectors provide signal connections between electronic devices using conductive terminals. Typically, the conductive terminals are closely spaced such that "crosstalk" occurs between adjacent conductive terminals. The mixed electric fields cause crosstalk when one conductive terminal induces electrical interference in adjacent conductive terminals, thereby compromising signal integrity. With the miniaturization and high speed of electronic devices, high signal integrity electrical communication becomes more common and the reduction of this crosstalk becomes an important factor in connector design. [0003] A commonly used technology for reducing crosstalk is to set ground terminals between adjacent signal terminals, such as an electrical connector disclosed in Chinese Inventio...
