CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims priority of a Chinese Patent Application No. 202010567796.4, filed on Jun. 19, 2020 and titled “BACKPLANE CONNECTOR ASSEMBLY”, and a Chinese Patent Application No. 202021462818.2, filed on Jul. 22, 2020 and titled “BACKPLANE CONNECTOR”, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a backplane connector which belongs to a technical field of connectors.

BACKGROUND

Existing backplane connectors usually include an insulating housing and a plurality of wafers assembled to the insulating housing. Each wafer includes an insulating frame, a plurality of conductive terminals insert-molded with the insulating frame, and a metal shield mounted to at least one side of the insulating frame. The conductive terminals usually include multiple pairs of differential signal terminals, a first ground terminal located on one side of each pair of differential signal terminals, and a second ground terminal located on the other side of each pair of differential signal terminals. The first ground terminal, the second ground terminal and the metal shield provide shielding for the differential signal terminals in order to reduce signal crosstalk and improve the quality of signal transmission.

However, there is still room for improvement in how to realize the fixation and positioning of the metal shield and the insulating frame.

SUMMARY

An object of the present disclosure is to provide a backplane connector, in which a first metal shield and a second metal shield can be easily positioned with an insulating frame.

In order to achieve the above object, the present disclosure adopts the following technical solution: a backplane connector comprising a wafer, the wafer comprising: a plurality of conductive terminals, each of the conductive terminals comprises a contact portion, a tail portion and a connection portion connecting the contact portion and the tail portion; an insulating frame fixed with the connection portions of the conductive terminals, and the contact portions and the tail portions extending beyond the insulating frame; a first metal shield located on one side of the insulating frame; and a second metal shield located on the other side of the insulating frame; wherein the conductive terminals comprise differential signal terminals, a first ground terminal and a second ground terminal, and the differential signal terminals are located between the first ground terminal and the second ground terminal; wherein the insulating frame comprises a plurality of first posts and a plurality of second posts; wherein the first metal shield comprises a plurality of first mounting holes to position the first posts; and wherein the second metal shield comprises a plurality of second mounting holes to position the second posts.

Compared with the prior art, the insulating frame of the present disclosure is provided with a plurality of first posts positioned in the first mounting holes and a plurality of second posts positioned in the second mounting holes. As a result, it is easy to realize the positioning of the first metal shield and the second metal shield with the insulating frame.
