HDMI (high definition multimedia interface)-DVI (digital visual interface) full HD digital image signal switching wire

Abstract

The invention discloses an HDMI (high definition multimedia interface)-DVI (digital visual interface) full HD digital image signal switching wire. The switching wire comprises a switching wire rod and a DVI connector. The switching wire is characterized in that a DVI wire clip is arranged between the switching wire rod and the DVI connector; after being soaked in tin, core wires in the switching wire rod are placed on the DVI wire clip; and the core wires soaked in tin and the DVI connector are welded together through HOTBAR welding. The switching wire has the following beneficial effects: the DVI wire clip is arranged between the switching wire rod and the DVI connector, thus improving the condition of poor electricity caused by high possibility of breaking of the welded joints of the core wires and the DVI connector, improving the product yield and saving the cost; the HOTBAR welding technology and the low-pressure plastic molding technology are adopted, thus greatly improving the product precision and yield and improving the production efficiency; and the wire rod has the external diameter as small as 3.65+ / -0.1mm and the external diameter is the smallest in the same specification of wire diameters in the world, thus saving the cost.

Description

technical field [0001] The invention relates to a high-definition digital image signal transfer cable, which belongs to the technical field of communication electronics. Background technique [0002] Taking the PC market as the forerunner, DVI has gradually entered the field of consumer electronics, and has become a digital interface commonly used in electronic equipment such as LCD monitors, notebooks and computers. In recent years, with the development of high-definition digital audio and video technology, the interface market has begun to change, and the consumer electronics market has begun to adopt the HDMI interface that can transmit high-quality digital audio and video. The HDMI-DVI digital image signal adapter cable came into being. At present, there are still many quality problems in the HDMI-DVI digital image signal adapter cable, such as the electrical defect of the adapter cable caused by the friable welding of the inner core wire of the wire and the connector, a...
