Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an FPC connector with an anti-outward snap-fit ​​and electronic equipment. Background Technology

[0002] FPC stands for Flexible Printed Circuit, characterized by its miniaturization, compact size, high density, simplified wiring procedures, reduced labor costs, excellent flexibility, adaptability, and foldability. It is widely used in electronic devices such as computer motherboards, LCD monitors, and external hard drives. Commonly used FPC connectors typically employ a flip-top design. When the flexible circuit board is inserted into the connector, flipping the cover causes the metal terminals inside the connector to engage with the flexible circuit board, simultaneously bringing the metal terminals into contact with the metal layer of the flexible circuit board.

[0003] However, the existing connectors do not provide sufficient clamping force for the FPC ribbon cable. When the ribbon cable is subjected to a certain backward pulling force, the cover is prone to flipping outward, causing the FFC to detach from the FPC, resulting in poor contact. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an FPC connector with an anti-outward flip-out latch and electronic equipment to solve the problem that the existing connectors do not have enough clamping force on the FPC ribbon cable, and the ribbon cable is prone to flipping outward when the cover is lifted when subjected to a certain backward pulling force.
