FFC winding displacement test compact structure

Technical Field

The utility model is applied to the technical field of compression structures, and particularly relates to an FFC (flexible flat cable) test compression structure.

Background

The FFC flat cable is a novel data cable formed by pressing PET or other insulating materials and an extremely thin tinned flat copper wire through a high-tech automatic equipment production line, and has the advantages of softness, random bending and folding, thin thickness, small volume, simple connection, convenient disassembly, easy solution to electromagnetic shielding (EMI) and the like. The cable is most suitable for being used as a data transmission cable between a mobile component and a main board, between board-to-board and in miniaturized electrical equipment. At present, the connecting device is widely applied to the connection between the printing head and the main board of various printers, the signal transmission of products such as plotters, scanners, copiers, audios, liquid crystal electric appliances, fax machines, various video players and the like, and the connection between boards. In modern electrical equipment, the FFC cable is widely applied, and a plurality of production enterprises need to perform related tests on the FFC cable so as to ensure the quality of the FFC cable and the quality of related products. When testing the FFC flat cable, the essential step is to fix the FFC flat cable so as to connect the FFC flat cable with the PCB for testing.

At present, most of compression structures for testing FFC (flexible flat cable) wires on the market adopt a screw locking mode, and when testing equipment requires high-speed operation, the screws are easy to loosen and even fall off due to reasons such as vibration, so that the testing result is influenced. Aiming at the problem, the pressing structure without screws is adopted, so that the problem can be effectively solved, and the pressing structure can be widely applied to high-speed FFC testing equipment.
