Low voltage differential signaling (LVDS) wire of parallel wire structure and manufacturing method thereof

Abstract

The invention provides a low voltage differential signaling (LVDS) wire of a parallel wire structure and a manufacturing method of the LVDS wire of the parallel wire structure. The LVDS wire comprises a stranded wire flexible flat cable (FFC), a flat FFC and an electronic connector. The stranded wire FFC comprises a plurality of strands of copper stranded wires, an upper layer insulating film and a lower layer insulating film. Two ends of the copper stranded wire are exposed outside, one exposed end is connected with the flat FFC in a welding mode, and the other exposed end is connected with the electronic connector in a welding mode. The flat FFC comprises a flat copper wire, an upper layer insulating film, a lower layer insulating film and a stiffening plate, wherein the upper layer insulating film and the lower layer insulating film are respectively attached to the flat copper wire in an up-and-down mode. One end of the flat FFC is punched into a buckle structure, and the flat copper wire with the other end being exposed is connected with the plurality of strands of copper stranded wires of the stranded wire FFC in a welding mode. The electronic connector comprises a connector upper cover and a connector body which is connected with the plurality of strands of copper stranded wires of the stranded wire FFC in a welding mode. The connector upper cover and the connector body are buckled. The LVDS wire of the parallel wire structure and the manufacturing method of the LVDS wire of the parallel wire structure have the advantages of being low in cost, high in production efficiency, long in buckling service life, controllable in characteristic impedance, fit for halogen-free requirement, good in shielding performance and the like.

Description

technical field [0001] The present invention relates to the technical field of signal lines, in particular to an LVDS (Low Voltage Differential Signaling, Low Voltage Differential Signaling) line with a parallel line structure and a manufacturing method thereof. Background technique [0002] At present, three kinds of LVDS lines are disclosed on the market, namely FPC (flexible printed circuit board), MIRCO COAXIAL CABLE (very thin coaxial cable MCC) and ELECTRONIC WIRE (electronic wire) are widely used in notebook computers, LCD, LED, etc. Electronic signal transmission of electronic products. [0003] The production process of the existing ELECTRONIC WIRE LVDS line is: bonding, cutting, Hot bar, dispensing and sealing, and inserting the plastic shell. This traditional structure mainly has the following disadvantages: [0004] 1. High cost: it needs to be sealed, plugged with rubber shell, etc., the process is complicated, and the labor cost is high; [0005] 2. Low produ...
