Backplane Connector System

Abstract

The invention provides a backboard connector system, which comprises a first backboard connector, a second backboard connector, a flexible circuit board connected between the first backboard connectorand the second backboard connector, and a pair of metal shields. Each metal shield comprises a base, and a cover body, wherein the base comprises a bottom plate and two side plates extending upward from the two sides of the bottom plate to accommodate and fix one end portion of the flexible circuit board; each side plate is provided with at least one slot sunken from the outer side surface to theinner side surface of the side plate, the depth of the slot being smaller than the distance between the outer side surface and the inner side surface of the side plate; the cover body comprises a topwall and two side walls extending downwards from the two sides of the top wall; and the side walls of the cover body are arranged at the outer sides of the side plates of the base respectively to cover one end portion of the flexible circuit board and one of the first backboard connector and the second backboard connector, and each side wall is provided with a perforated hole in the place corresponding to each slot to allow a screw to be screwed into the slot via the perforated hole.

Description

technical field [0001] The present application relates to the field of connectors mounted on a circuit substrate, and more particularly relates to a connector suitable for backplane applications. Background technique [0002] Communication systems, such as networking systems, servers, data centers, etc., use large printed circuit boards called backplanes to interconnect midplanes, daughter cards, line cards, and / or switch cards. Communication systems use high-speed differential connectors that mount to backplanes and high-speed differential connectors that mount to line cards and switch cards to transmit signals between them. Backplane connectors need a reasonably high density (sometimes called pins per inch) while supporting data channels with high signal frequencies. [0003] However, backplane connector systems operating at high data transfer rates are often susceptible to electromagnetic interference (EMI). In traditional designs, EMI is reduced or suppressed by surrou...

Problems solved by technology

However, because the metal casing often uses a split design of the upper and lower casings, the connection of the upper and lower casings has brought problems.

In the prior art, screws are often used to connect the upper and lower casings. When the screws are screwed into the through holes in the casing, debris is likely to be generated, such as iron filings, which will enter the backplane connector, causing short circuits and malfunctions. problem that prevents the backplane connectors from functioning properly
