Abstract

The invention discloses a QSFP connector for high-frequency signal transmission. The QSFP connector comprises an insulating body, a terminal module group and a terminal holding member for holding the terminal module in sequence in the insulating body. The terminal module group comprises signal terminal groups consisting of grounding terminals and several signal terminals. The signal terminals comprise contact portions, installation portions, connection contact portions and connecting portions of the installation portions. The grounding terminals comprise substrates, several contact portions formed by folding and extending the lower parts of the left sides of the substrates along the length directions of the substrates and several mounting portions corresponding to the contact portions and formed by folding and extending the lower parts of the right sides of the substrates in the longitudinal directions of the substrates. The mounting portions, the contact portions, the substrates and the other mounting portions form bridge-shaped grounding terminals. Space is arranged between each adjacent two contact portions and space is arranged between each adjacent two mounting portions. Each space is correspondingly provided with one signal terminal group. The beneficial effects of the present invention are that an independent grounding terminal in the prior art is arranged to be a set of grounding terminals, so that the grounding effectiveness of the grounding terminals is raised, and the shielding effect is increased.

Description

technical field [0001] The invention relates to the technical field of QSFP high-speed electrical connectors, in particular to a QSFP connector for high-frequency signal transmission that improves the shielding effect by improving the structure of the grounding plate. Background technique [0002] QSFP (Quad Small Form-factor Pluggable): Four-channel SFP interface (QSFP), QSFP was born to meet the market's demand for higher-density high-speed pluggable solutions. QSFP high-speed signal electrical connector is widely used in communication, storage, data transmission, etc. It can be used as an optical fiber solution, and its speed and density are better than 4-channel CX4 interface. Since it can support four channels of data transmission at a speed of 10Gbps per channel under the same port volume of XFP, the density of QSFP can reach 4 times that of XFP products and 3 times that of SFP+ products. The QSFP interface with 4 channels and higher density than CX4 has been adopted ...
