Forming method of data line

Abstract

The invention discloses a data line and a forming method thereof. The data line comprises a data joint, a transmission lead and an insulation layer which is integrally coated on the outer surface of the data joint and the outer surface of the transmission lead, wherein the insulation layer comprises an upper insulation part subjected to primary forming and a lower insulation part subjected to secondary forming; the upper insulation part is correspondingly coated on the outer surface of the upper end of the data joint and outer surface of the upper end of the transmission lead; and the lower insulation part is correspondingly coated on the outer surface of the lower end of the data joint and the outer surface of the lower end of the transmission lead, and the lower insulation part is fit with the upper insulation part and plastified with each other in the secondary forming process, thus effectively solving the problems that the thickness of the insulation layer is uneven because of shift of the transmission lead, and the like. A positioning needle does not need to be used in the mould in the invention, the outer surface of the insulation layer has no positioning hole, the outer surface of the insulation layer is smooth and beautiful and is well coated; and the upper insulation part and the lower insulation part can be formed by adopting materials of different colors, and when the data line is used, the insertion direction is conveniently distinguished, and the phenomena of reverse insertion and the like are not easy to occur.

Description

technical field [0001] The invention relates to the technology in the field of data transmission devices, in particular to a method for forming a data line that is easy to manufacture, well coated with an insulating layer, and has a neat, smooth and beautiful outer surface. Background technique [0002] With the development of science and technology, digital products have gradually become necessities in life, such as computers, digital cameras, mobile phones, etc., and the conversion or copying between these digital products is generally transmitted through data lines. [0003] The current data lines mainly include interconnected data connectors and transmission wires. During production, the outer part of the transmission wires is generally coated with an insulating sleeve by means of extraction, and then the transmission wires are connected to the data connectors. Finally, the data connectors An insulating layer is overmolded on the outer surface and the connection position...

AI Technical Summary

Problems solved by technology

However, in the actual production process, this method still has some deficiencies. For example, due to the uneven upper and lower pressure in the mold, the transmission wire is easily shifted, resulting in uneven thickness of the coated insulating layer. It affects the quality of the product; if in order to solve the above-mentioned offset problem of the transmission wire, positioning pins are usually added in the mold to position the transmission wire, often the outer surface of the insulating layer formed will form a positioning hole, which is not conducive to the insulation layer. It protects the internal transmission wire and affects the smoothness and aesthetics of its outer surface
