Connector and backplane interconnecting system

Abstract

The embodiment of the invention provides a connector and a backplane interconnecting system, and relates to the technical field of communication equipment. The connector comprises a connector shell, wherein the connector shell is an insulator, and comprises at least two connecting end faces; a shielding member is disposed at least one connecting end surface, wherein the shielding member has conductivity, and a plurality of isolation holes and a plurality of connecting holes are configured on the shielding member; the connector further comprises a plurality of plug-in terminals; the plurality of plug-in terminals include signal terminals for transmitting signals and ground terminals for grounding; one or more adjacent signal terminals constitute a signal terminal group; a plurality of signal terminal groups are used for transmitting different electrical network signals or different differential signals; the plurality of signal terminal groups penetrate through the plurality of isolationholes in a one-to-one correspondence mode, and the signal terminals in the signal terminal groups are not in contact with the hole walls of the corresponding isolation holes; and the plurality of ground terminals penetrate through the connecting holes in a one-to-one correspondence mode, and the ground terminals at least are partially in contact and conductive with the hole walls of the connecting holes.

Description

technical field [0001] The present application relates to the technical field of communication equipment, in particular to a connector and a backplane interconnection system. Background technique [0002] With the upgrade of the communication rate, the system puts forward more stringent requirements on the high-speed electrical performance indicators of the connector, among which the most critical electrical performance indicators are crosstalk, loss and reflection. Among them, crosstalk includes far-end crosstalk and near-end crosstalk, which is manifested as noise injection to the victim network, which directly reduces the signal-to-noise ratio of the signal and degrades the quality of signal transmission. As the rate of the current main communication products evolves to 56Gbps or even 112Gbps, crosstalk has gradually become one of the main challenges for connectors. From the perspective of the specification requirements for connector crosstalk, in the frequency domain, t...

Problems solved by technology

However, from figure 2 It can be seen from the figure that the second conductive casing 07a and the ground strip 09a do not form an effective isolation between the signal strip 081a and the signal strip 082a, and the second conductive casing 07b and the ground strip 09b do not form an effective isolation between the signal strip 081b and signal strip 082b to form an effective isolation, resulting in between signal strip 081a and signal strip 082a, and between signal strip 081b and signal strip 082b still exist figure 2 The signal interference path shown by the dotted line in the middle, so the shielding effect is not good

And because a set of insulating shells and conductive shells are arranged on each sheet-like piece, the number of parts is large, assembly is difficult, the process is complicated and the cost is high
