Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Specific embodiment one of the shielding member of the backplane connector of the present invention, such as Figure 1 to Figure 5 As shown, the backplane connector is used in the signal transmission process, including the base 1. For the base 1, it is made of insulating material, and the whole is a U-shaped board structure, including two opposite vertical boards 11, and connecting On the bottom plates of the two vertical plates, a plurality of guide grooves are provided on the inner side of each vertical plate 11 to guide and fix the sub-board connectors docked with it, and the bottom plate of the U-shaped plate constitutes a differential The differential pair mounting board 12 of the pair. Of course, in other embodiments, the structural forms of the base 1 and the differential pair mounting plate 12 can be designed arbitrarily according to actu...

Abstract

The invention relates to a shielding piece of a back panel connector. The shielding piece comprises a shielding piece body, wherein the shielding piece body is arranged at an upper side or a lower side of a differential pair installation plate, an avoidance hole is formed in the shielding piece body and is used for avoiding a differential pair, and a contact part is further arranged on the shielding piece body and is used for being contacted and connected with each grounding pin on the differential pair installation plate. By forming the avoidance hole in the shielding piece body, the corresponding differential pair is annularly shielded; meanwhile, by arranging the contact part, used for being contacted with the grounding pin to achieve shielding connection of each grounding pin, on the shielding piece body, all grounding pins can be connected in series, the shortest signal return path is provided for an encircled signal, resonance is moved backwards within frequency domain, and larger transmission bandwidth is provided.

Description

technical field [0001] The invention relates to a shield 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 U.S. Patent Publication No. US2007155241A1, there are a plurality of L-shaped shielding sheets arranged in a matrix in the backplane connector, and each L-shaped shielding sheet is a grounding pin, and the L-shaped shielding sheets are connected to each other. 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, cau...
