Plug-in connector for differential data transmission

Abstract

The invention discloses a plug-in connector for differential data transmission. The plug-in connector comprises a plug connector and a socket connector; the plug connector comprises a plug tail sleeveand a plug insulator; the plug tail sleeve is mounted in a plug shell; the plug insulator is mounted in the plug tail sleeve; the plug insulator is provided with a plurality of axially-arranged protrusions in the circumferential direction; the same side of each protrusion is provided with plug sheet type contact pieces arranged in parallel; the plug sheet type contact pieces located on the side parts of the adjacent protrusions are perpendicular mutually; the socket connector comprises a socket tail sleeve mounted in a socket shell and a socket insulator mounted in the socket tail sleeve; a cavity matched with the plug insulator in an inserted mode is formed in the socket insulator; and the cavity is internally provided with socket sheet type contact pieces which correspond to the plug sheet type contact pieces and are matched with the plug sheet type contact pieces in a mutual pushing mode to realize electrical connection. According to the plug-in connector, through reasonable spatial distribution of the contact pieces, the product miniaturization development trend can be adapted, and the short pile effect and the signal crosstalk during high-frequency signal transmission can beeffectively eliminated.

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
