Abstract

The invention relates to a grounding pin of a backplane connector. The grounding pin includes a grounding pin body for being installed on a differentiator mounting plate. The first contact part for layer contact and conduction and / or the second contact part for overhanging to the lower side of the differential installation board and contacting the lower shielding layer, through the top pressure of the upper shielding layer and the first contact part conduction, the shielding conduction between the lower shielding layer and the second contact part connects the grounding pin to the corresponding shielding layer, thereby providing the shortest signal return path for the surrounded signal, thereby moving the resonance backward in the frequency domain Over time, it provides greater transmission bandwidth. Furthermore, the provision of the first contact portion and the second contact portion can ensure good electrical contact between the corresponding shielding layer and the grounding pin.

Description

technical field [0001] The invention relates to a ground pin of a backplane connector. 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 outside the corresponding differential pairs, so as to realize the corresponding differential pair Provides electromagnetic shielding. [0003] In the prior art, as shown in the U.S. patent document with the publication number US2007155241A1, there are a plurality of L-shaped shielding sheets arranged in a matrix in the backplane connector, each L-shaped shielding sheet is a grounding pin, and the L-shaped shielding sheet The surrounding differential pairs have a shielding effect to reduce crosstalk, but the ground pins are not connected to each other inside the backplane connector, so each ground pin is an independent signal return path, resultin...
