The invention relates to a ground pinch plate and a backplane connector and connector assembly using the ground pinch plate. 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 a In order to avoid the avoidance hole of the differential pair and the through hole for the ground pin to pass through, the edge of the through hole is provided with an elastic contact part for contacting each ground pin to conduct each ground pin, and the elastic contact between the ground pin and the conductive plate body The internal elastic top press fit to achieve conduction, so that all the ground pins are connected in series through the ground pinch plate, so as to provide the shortest signal return path for the surrounded signal, thereby pushing the resonance back in the frequency domain, providing a larger transmission bandwidth. At the same time, the structural form of the elastic contact part can ensure the stable contact between the grounding pin and the conductive plate body, and ensure the effectiveness of conduction.
Description
technical field [0001] The invention relates to a grounding plate, a backplane connector and a connector assembly using the grounding plate. 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 wi...
