Problems solved by technology

However, the shielding effect of this technical solution using a single shielding sheet is average, and it is usually only suitable for systems with a transmission rate lower than 10Gbps. For the transmission of higher-speed signals, such as high-speed systems with a transmission rate of 25Gbps or even 50Gbps, a further step is required. Signal connectors that reduce crosstalk and meet system requirements

Abstract

The embodiment of the invention discloses a signal connector. The signal connector comprises a first plug-in connector and a second plug-in connector, wherein the first plug-in connector comprises a signal transmission unit comprising a signal transmission part, a first shielding component and a second shielding component, and a first matched fixing end for containing the signal transmission unit; the second plug-in connector comprises a second matched fixing end for containing a second signal terminal pair and a third shielding component; and when the first plug-in connector is in plug-in connection with the second plug-in connector, a first signal terminal pair and the second signal terminal pair are arranged in a connection way, the third shielding component and a first clamping joint of the signal transmission unit are arranged in a clamping way, the third shielding component is connected with the first shielding component and the second shielding component in a clamping way so as to form an O-shaped shielding cavity structure coating the first signal terminal pair and the second signal terminal pair, and the O-shaped shielding cavity structure is used for shielding the signals transmitted by the first signal terminal pair and the second signal terminal pair. By the embodiment, the signal crosstalk problem of the signal connector in a high-speed system can be solved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a signal connector used in a high-speed signal transmission system. Background technique [0002] In the field of data transmission, the signal transmission speed of communication equipment is getting faster and faster. In high-speed systems, connectors for differential signals are usually used, and when high-speed signals pass through the connectors, the crosstalk between signals will be relatively large, so signal isolation is required. At present, for high-speed signals with a rate exceeding 3 Gbps, a metal shielding sheet is usually used to shield the signal lines. However, the shielding effect of this technical solution using a single shielding sheet is average, and it is usually only suitable for systems with a transmission rate lower than 10Gbps. For the transmission of higher-speed signals, such as high-speed systems with a transmission rate of 25Gbps or even 5...
