Problems solved by technology

[0003] At present, the PCI-SIG Association has announced that the signal transmission rate of the PCIe4.0 specification has reached 16GT / s, and the transmission bandwidth has reached 64Gbps, while the PCIe5.0 specification currently under development announced by the PCI-SIG Association will further double the signal transmission rate. It has reached 32GT / s, and its transmission bandwidth has even reached 128Gbps. In such a rapidly developing field of high-frequency connectors, the grounding piece in the prior art has been unable to meet its high-frequency performance. At the same time, the contact of the grounding piece The pin is connected to the ground terminal by lapping, which may cause poor contact

Abstract

An electrical connector, comprising an insulating body, a plurality of conductive terminals arranged on the insulating body, and a grounding piece, the conductive terminals include several pairs of differential signal terminals and a plurality of grounding terminals arranged in a row, and the grounding terminals are separated by Arranged between two adjacent pairs of differential signal terminals, the ground sheet is integrally provided with a number of first connection parts, second connection parts and third connection parts, and each of the ground terminals is connected to a The first, second and third connecting parts, the first, second and third connecting parts are connected to the ground terminal by spot welding, which can establish a stable electrical contact, and then realize an improved electrical connector Efficacy for signal crosstalk and improving high-frequency transmission performance.

Description

【Technical field】 [0001] The present invention relates to an electrical connector, in particular to an electrical connector for high frequency transmission. 【Background technique】 [0002] For related prior art, please refer to a high-frequency connector with a transmission bandwidth of 6 Gbps disclosed in US Patent Publication No. US20090221165, which includes an insulating body and a plurality of conductive terminals held on the insulating body. The conductive terminals include grounding terminals and pairs arranged in pairs. The differential signal terminal of the device, a grounding plate is provided with a plurality of integrally extending contact pins, and a plurality of contact pins are respectively overlapped with each grounding terminal to reduce signal crosstalk and improve the high-frequency performance of the connector. [0003] At present, the PCI-SIG Association has announced that the PCIe4.0 specification signal transmission rate has reached 16GT / s, and the tr...
