Abstract

The invention discloses an electric connector, which comprises at least one electric module, and is characterized in that the electric module comprises: a plurality of terminal assemblies, wherein each terminal assembly comprises two signal terminals with the same length, the two signal terminals are arranged along a first direction to form a differential pair, and the narrow sides of the two signal terminals are coupled; an insulating body which is provided with a plurality of accommodating grooves which are arranged in a second direction perpendicular to the first direction, wherein each accommodating groove is used for accommodating the corresponding terminal assembly; and at least one shielding piece which is fixed on the insulating body and is electrically isolated from the signal terminals, wherein two sides of the terminal assembly in the first direction are defined as a first side and a second side respectively, the shielding piece only shields one of the first side and the second side of each terminal assembly in the first direction, and one of the signal terminals in each differential pair is adjacent to the shielding piece in the first direction relative to the other signal terminal. The electric connector is good in high-frequency performance, interference attacks of differential pairs to outward emission can be reduced, and interference to the outside is reduced.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector with good high-frequency performance. 【Background technique】 [0002] With the continuous improvement of the high-frequency performance requirements of electrical connectors, the high-frequency problems of electrical connectors are becoming more and more prominent, and the design requirements for various indicators related to the high-frequency performance of electrical connectors are also getting higher and higher, such as characteristics Impedance size, impedance consistency, signal transmission delay, interference noise, resonance, signal loss, external interference attacks, and large current transmission, etc. [0003] The debugging of various indicators is mutually restrained and affected. For example, in order to achieve the required characteristic impedance of the terminal, it is necessary to adjust the cross-sectional size of the terminal, the distance ...
