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 electric connector comprises an insulation body, a plurality of conductive terminals arranged on the insulation body and a grounding piece; the conductive terminals comprise a plurality of pairs of differential signal terminals arranged in a row and a plurality of grounding terminals, and the grounding terminals are arranged between two adjacent pairs of differential signal terminals at intervals. The grounding piece is integrally provided with a plurality of first connecting parts, second connecting parts and third connecting parts, each grounding terminal is respectively connected with the first connecting parts, the second connecting parts and the third connecting parts at different positions, and the first connecting parts, the second connecting parts and the third connecting parts are connected with the grounding terminals in a spot welding manner, so stable electric contact can be established; therefore, the signal crosstalk of the electric connector is improved, and the high-frequency transmission performance is improved.

Description

【Technical field】 [0001] The 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 up to 6Gbps disclosed in U.S. Patent Publication No. US20090221165, which includes an insulating body and a number of conductive terminals held in the insulating body. The differential signal terminals of the ground plate are provided with a plurality of integrally extending contact pins, and the contact pins are respectively overlapped with each ground 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 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 announ...
