Title:
CONNECTOR, FUNCTIONAL BOARD AND BOARD-LEVEL ARCHITECTURE
Document Type and Number:
WIPO Patent Application WO/2022/135362
Kind Code:
A1
Abstract:
A connector (6), a functional board and a board-level architecture. The connector (6) comprises an end protection plate (30) and lead frames (20); each lead frame (20) comprises a plurality of connection terminal groups (22) and shielding layers (21, 23); each connection terminal group (22) comprises two connection terminals (221, 222) for transmitting signals, and each of the connection terminals (221, 222) has a first connection end in an insertion fit with a circuit board (5); and the shielding layers (21, 23) are used for electromagnetically isolating the connection terminal groups (22) of adjacent lead frames (20). The end protection plate (30) comprises a conductive structure (32) between the first connection ends of the two connection terminals (221, 222) in each connection terminal group (22); and the conductive structures (32) are conductively connected to the shielding layers (21, 23) of the corresponding connection terminal groups (22), and are used for transmitting loop signals corresponding to differential signals. In the described technical solution, the conductive structures (32) on the end protection plate (30) improve a transmission path of a loop signal corresponding to a differential signal transmitted by each connection terminal group (22), reduce the crosstalk between the loop signals of different connection terminal groups (22), and increase the communication effect of the connector.
