Backboard connector socket

Abstract

The invention provides a backboard connector socket. The backboard connector socket comprises a plurality of wafer units, a plurality of connecting fisheyes and a protective sleeve. The plurality of wafer units are arranged side by side along a first direction, each wafer unit is provided with a mounting end, the mounting end of each wafer unit is fixedly connected with a plurality of connecting fisheyes, and each connecting fisheye at least partially protrudes out of the mounting end of the corresponding wafer unit. The protective sleeve is fixedly arranged at the mounting end of each wafer unit, the connecting fisheye on each wafer unit penetrates through the protective sleeve, a metal coating is arranged on the surface of one side, close to the mounting end, of the protective sleeve, and the surface of one side, away from the mounting end, of the protective sleeve is insulated. Wherein part of the connecting fisheyes do not make contact with the metal coating so as to transmit high-speed signals, part of the connecting fisheyes are electrically connected through the metal coating so as to achieve common-ground interconnection at the positions, making contact with the metal coating, of the part of the connecting fisheyes, and then crosstalk and resonance are prevented from being generated between the connecting fisheyes used for transmitting the high-speed signals.

Description

technical field [0001] The present application relates to the technical field of connectors, in particular to a backplane connector socket. Background technique [0002] Backplane connector sockets are used to transmit high-speed signals, and crosstalk between differential signals needs to be minimized effectively. Usually, the backplane connector socket usually has a plurality of wafer units arranged side by side, and several connection fisheyes are extended from each wafer unit to form several connectors to connect with the connected equipment. The connection fisheyes are used for high-speed signal transmission or for ground shielding to ensure good data transmission capability of the backplane connector socket. Since multiple connecting fisheyes are arranged at different angles at different positions of the wafer and multiple first grounding fisheyes and multiple second grounding fisheyes are arranged in the same shape, due to the large number and dense distribution, it ...
