Manufacturing method of connecting wire with high-definition multimedia interface

Abstract

The invention discloses a manufacturing method of a connecting wire with a high-definition multimedia interface, comprising the following steps of: firstly cutting a wire, peeling the sheath of the wire, twisting the wire, peeling a core wire, welding and then testing for the first time, wherein products unqualified in the first test are returned to be welded again; after the products are qualified in the first test, assembling an upper plastic shell and a lower plastic shell with injection molding on a head part of a metal head of the high-definition multimedia interface and a cable wire thereof; then welding the upper plastic shell and the lower plastic shell by adopting an ultrasonic welding machine; performing a final test after the upper plastic shell and the lower plastic shell are welded, wherein the products qualified by the finial test are packaged and stored, and the products unqualified by the final test are reassembled with a shell or returned to the welding procedure to be welded again after the shell is removed. The manufacturing method is suitable for manufacturing the connecting wire with the high-definition multimedia interface.

Description

technical field [0001] The invention relates to a manufacturing method of a connection line with a high-definition multimedia interface. Background technique [0002] The full English name of high-definition multimedia interface is: "High Definition Multimedia Interface", abbreviated as HDMI, HDMI interface can provide up to 5Gbps data transmission bandwidth, can transmit uncompressed audio signals and high-resolution video signals. At the same time, there is no need to perform digital / analog or analog / digital conversion before signal transmission, which can ensure the highest quality video and audio signal transmission. At present, the technological process of the manufacturing method of the high-definition multimedia interface connection line is as follows figure 2 As shown, the main contents of each process in the process flow are as follows: 1. Wire cutting: According to customer needs, the cable wire is cut to a specified length; 2. Sheathing: The cable wire end is str...

AI Technical Summary

Problems solved by technology

[0003] From the above, it can be seen that the traditional manufacturing method has the following disadvantages: (1) Since the inner mold and the outer mold are directly injected on the HDMI interface, the probability of poor electrical performance during the production process is relatively high, including: open circuit, short circuit, poor contact

(2) During the production process, due to factors such as equipment, molds, materials, and worker operating levels, it is easy to have poor appearance when injecting the outer mold, including: molding blisters, shrinkage, and molding dissatisfaction

After the above problems occur, the outer mold or inner mold must be cut off, and then return to the welding process, resulting in a waste of manpower and material resources, and at the same time increasing the manufacturing cost
