The invention relates to a backplane connector, its ground pinch plate, and a connector assembly. The ground pinch plate includes a conductive plate body for fixing on one side of a differential pair mounting plate, and the conductive plate body is provided with an avoidance plate for avoiding the differential pair. hole and a through hole for the ground pin to pass through. The edge of the through hole is provided with a contact part for contacting each ground pin to conduct each ground pin. The conductive plate body is also provided with a card slot for the differential pair mounting plate The snap-fit connection connects the conductive plate body and the differential pair mounting plate fixedly, and connects all the grounding pins in series through the grounding plate, providing the shortest signal return path for the surrounded signal and keeping the resonance in the frequency domain Push back to provide greater transmission bandwidth. The clamping connection is relatively fixed to ensure the stability of the shielding structure, and can realize stable support for the contact conduction of the grounding pin. This fixed form of the clamping connection is relatively convenient for assembly and disassembly, and the assembly efficiency is high.
Description
technical field [0001] The present invention relates to a backplane connector, its grounding plate, and a connector assembly. Background technique [0002] The backplane connector in the prior art includes several signal terminals and ground pins, wherein the signal terminals are arranged in the form of differential pairs, and the corresponding ground pins are arranged on the outside of the corresponding differential pairs, so as to realize the matching of the corresponding differential pairs. Provides electromagnetic shielding. [0003] In the prior art, as shown in U.S. Patent Publication No. US2007155241A1, a plurality of L-shaped shielding sheets arranged in a matrix are arranged on the differential pair mounting plate of the backplane connector, and each L-shaped shielding sheet is a grounding pin, The L-shaped shielding sheet has a shielding effect on the surrounding differential pairs, thereby reducing crosstalk, but each ground pin does not conduct with each other i...
