Plug-in connectors for differential data transmission

Abstract

A plug connector for differential data transmission, including a plug connector and a socket connector, the plug connector includes a plug tail sleeve installed in the plug housing and a plug insulator installed in the plug tail sleeve, the plug The insulator has a plurality of axially arranged protrusions along the circumferential direction, and plug blade contacts arranged side by side are arranged on the same side of each protrusion, and the plug blade contacts on the sides of adjacent protrusions are arranged perpendicular to each other; The socket connector includes a socket tail sleeve installed in the socket housing and a socket insulator installed in the socket tail sleeve. The socket insulator is provided with a cavity that is mated with the plug insulator. The contact pieces are corresponding and push-fit with each other to realize the socket blade contact pieces for electrical connection. The invention adapts to the development trend of product miniaturization through the reasonable spatial distribution of the contact parts, and can effectively eliminate the stub effect and signal crosstalk during high-frequency signal transmission.

Description

technical field [0001] The invention belongs to the field of differential connectors, in particular to a plug connector for differential data transmission. Background technique [0002] Differential connectors are mainly used for high-speed data signal transmission, the existing M12 differential connectors such as figure 1 As shown, the cross shield structure 7 is used to divide the eight round pin / round hole contacts into four differential pairs, and the cross shield structure is connected to the shell shield to play a shielding role to achieve high-speed performance transmission. With the development of miniaturization of this type of connector products, this structure cannot be applied to products with smaller dimensions, mainly because the cross-shielding structural parts are more demanding on processing technology, and due to the limitation of volume and minimum wall thickness, it cannot be made smaller ; If the part wall of the cross shielding structure is too thin, i...

Problems solved by technology

With the development of miniaturization of this type of connector products, this structure cannot be applied to products with smaller dimensions, mainly because the cross-shielding structural parts are more demanding on processing technology, and due to the limitation of volume and minimum wall thickness, it cannot be made smaller ; If the part wall of the cross shielding structure is too thin, it will not only fail to meet the processing requirements of the part, but also be easily damaged during the insertion process
