Description

Technical Field

[0001] This utility model relates to an electrical connection component with shielding function. Background Technology

[0002] In existing technologies, shielded electrical connection components mainly consist of a metal spring clip overlapping an aluminum foil surface. One method involves attaching an aluminum foil layer to the surface of the FFC (Flexible Flat Cable) wire, directly overlapping the metal grounding area of ​​the connector with the aluminum foil to achieve grounding. However, under vibration conditions, this grounding method has poor connection reliability and is prone to disconnection. Another method involves adding an independent metal plate to the side of the FFC wire, with the surface of the FFC wire also covered by aluminum foil. The metal plate and aluminum foil must be conductive and overlap with the grounding area of ​​the connector to achieve grounding. Although this grounding method has better reliability, it requires higher precision in wire manufacturing processes and is complex to produce. Utility Model Content
