Video signal converter connecting line and processing method thereof

Abstract

The invention discloses a processing method of a video signal converter connecting wire. The processing method comprises the following steps of (1) firstly, removing a sheath at an end part of a connecting cable to expose a braid layer at the end part of the connecting cable; (2) stamping and coating a copper strip ring with a specified length outside the braid layer exposed out of the end part ofthe connecting cable, and then cutting off the redundant braid layer exposed out of the copper strip ring; (3) correspondingly welding a core wire of the connecting cable and the joint together; (4)injecting an insulating inner mold at the corresponding welding part of the core wire of the connecting cable and the joint; (5) coating the inner mold with a self-adhesive copper foil; (6) welding the self-adhesive copper foil coating the outside of the insulating inner mold and a copper strip ring together; and (7) welding the self-adhesive copper foil coating the outside of the insulating innermold and the joint shell together. The method has the advantages that the processing time is short, the processing difficulty is low, the production efficiency can be improved, the shielding performance of the connecting wire can be improved, and the appearance quality of the connecting wire can be improved.

Description

technical field [0001] The invention relates to the technical field of video signal converter manufacturing technology, in particular to a video signal converter connecting wire and a processing method thereof. Background technique [0002] At present, there are many video signal transmission formats in the world, such as: CVBS, VGA, DP, DVI, HDMI, USB, etc. Among them, CVBS and VGA are the transmission formats of analog signals, while DP, DVI, HDMI, and USB are digital signals. Transmission formats, they have been widely used in various devices and household appliances. [0003] Due to the different signal transmission formats, it will inevitably lead to the incompatibility of signal transmission between devices and electrical appliances using different signal formats. It is impossible to watch on TV. At this time, a video signal converter is needed: convert the USB signal output by the computer to the HDMI signal format. [0004] Because there are many signal formats, t...

Problems solved by technology

[0019] The processing method of the above connecting wire has the following defects: 1) When the inner mold is injected, the sealing position of the rubber material is on the core wire of the connecting cable, which can easily cause the rubber material to rush to the inside of the connecting cable, resulting in poor appearance; 2) When the inner mold is injected, the braided wire that is brushed back for the first time is easily broken by the mold, resulting in a reduction in the number of braided wires welded to the copper foil, and the gap after welding becomes larger, which affects the appearance quality of the connecting wire and reduces the quality of the connecting wire. 3) After the inner mold is injected, when the copper wire is brushed back on the copper foil again, it is not easy to brush back evenly, and the gap becomes larger, which affects the appearance quality of the connecting wire and reduces the shielding performance of the connecting wire; 4) Copper The wire is brushed against the copper foil and cannot be attached to the copper foil. It is very difficult to weld and affects production efficiency; 5) When braided wire and copper foil are welded, it is necessary to accurately control the welding time, otherwise it will easily cause braided wire to be welded at the same time. It takes a long time to weld the other side, and the one that has been welded is desoldered again, which affects production efficiency
