Connector, functional board, and board-level architecture

Abstract

A connector includes an end protector and lead frames. Each lead frame includes a plurality of connection terminal groups and a shield layer. Each connection terminal group includes two connection terminals configured to transmit a signal. Each connection terminal has a first connection end that cooperates with insertion of a circuit board. The shield layer is configured to electromagnetically isolate connection terminal groups in adjacent lead frames. An end protector includes a conductive structure that is located between the first connection ends of the two connection terminals in each connection terminal group. In the foregoing technical solution, with the conductive structure on the end protector, a transmission path of a loop signal corresponding to a differential signal transmitted by each connection terminal group is improved, crosstalk between loop signals corresponding to different connection terminal groups is reduced, and communication effect of the connector is improved.
