Embodiment Construction

[0035] In order to facilitate the understanding of the connector provided by the embodiments of the present application, several terms related to the connector are first introduced:

[0036] Shielding layer: The shielding layer refers to the whole piece of metal sheet, which needs to be grounded and has the effect of electromagnetic shielding.

[0037] Connection terminal: A connection terminal refers to a metal lead used to transmit a signal or provide a return path for the signal.

[0038] Crosstalk: Crosstalk refers to the coupling effect of unwanted electrical signals passing from one network to another, which in this application refers to crosstalk between different groups of connection terminals.

[0039] Insertion loss: Insertion loss refers to the loss of energy in the process of signal transmission from one end of the terminal to the other.

[0040] Lead frame: refers to the main structure composed of connector signal terminals, shielded conductors, and insulators. ...

Abstract

The invention provides a connector, a function board and a board-level architecture, the connector comprises an end protection sheet and lead frames, and each lead frame comprises a plurality of connection terminal groups and a shielding layer; each connecting terminal group comprises two connecting terminals used for transmitting signals, and each connecting terminal is provided with a first connecting end matched with a circuit board in an inserting manner; and the shielding layer is used for electromagnetically isolating the connecting terminal groups of the adjacent lead frames. The end protection sheet comprises a conductive structure located between the first connecting ends of the two connecting terminals in each connecting terminal group; the conductive structures are in conductive connection with the shielding layers of the corresponding connection terminal groups and are used for transmitting loop signals corresponding to the differential signals. According to the technical scheme, the transmission path of the loop signal corresponding to the differential signal transmitted by each connection terminal group is improved through the conductive structures on the end protection sheets, crosstalk between the loop signals of different connection terminal groups is reduced, and the communication effect of the connector is improved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular, to a connector, a functional board and a board-level structure. Background technique [0002] In the current communication equipment system, the interconnection system based on the combination of the PCB backplane and the daughter card is the most common interconnection architecture. Various daughter cards are connected to the backplane through backplane connectors. As the connection bridge between the backplane and daughter cards, the connector acts as a key fabric-level component. [0003] The backplane connector is usually required to support the evolution and upgrade of the product during the life cycle. Specifically, in terms of high-speed electrical performance, it generally needs to support at least two generations of rate upgrades. With the speed upgrade, the system has more stringent requirements on the high-speed electrical performance of the connec...
