In recent years, the application fields of audio and video have changed, such as audio and video discs, digital versatile discs, high-definition digital TVs, audio-visual phones and video conferencing, etc., which are rapidly emerging in our lives and in new technologies. Under the leadership of the trend, most audio and video video uses digital methods to process voice and video information. With the application and needs of different fields, some related standards are constantly being developed, revised and updated. Users can enjoy higher quality, excellent audio and video effects, and the speed of digital signal transmission must be more complete and fast.

However, general digital video interfaces, such as Display Port, Digital Video Interface (DVI), High Resolution Multimedia Video Interface (HDMI), etc., can be plugged into adapters, set-top boxes, DVD players, and individuals. Computers, TV game instruments, integrated amplifiers, digital audio and other peripheral devices can enhance the picture quality displayed by electronic products through digital transmission, and have the characteristics of high transmission rate, long distance, high video and audio quality, and wide. It is popular with the public and the number of uses is increasing.

Most of the wires used for displaying 埠, digital video interface and high-resolution multimedia audio and video interface are in a circular or flat cable structure, and the plurality of core wires (such as high-frequency signal lines and low-frequency signals) are inside the cable. The wire and the grounding wire are electrically connected to the internal terminal group of the connector socket of the connector, and when the connector transmits the signal, the grounding circuit can be connected to the shielding shell of the external cover of the socket to form a grounding circuit. In turn, the noise such as noise or crosstalk on the cable is guided to the ground for dissipation, and has a good grounding function.

Due to the welding method of the terminal group of the current connector and the plurality of core wires inside the circular cable, the outer layer of the cable is manually stripped, and the plurality of core wires are arranged in a scattering manner, and the respective core wires are sequentially arranged. The core layer is stripped by a stripping machine, which will cause the bare core wires to be jagged and of varying lengths, and because of the different definitions of the pin groups of the terminal group, when the plurality of core wires are welded to the terminal group, the core of the core wire It must be matched with the pin position of the terminal group respectively, so that the circular cable needs to be manually connected one by one to the pin position of the terminal group, and then the subsequent welding operation is performed, which will not only cause part of the core wire. The jumps are entangled, making the manufacturing process quite cumbersome, and it is easy to cause the accuracy error in the manual alignment due to the increase in the number of terminal groups, the spacing between them is narrow, and the manufacturing difficulty and labor Time and cost, and when the core wires are entangled, the signal transmission is unstable, which will affect the quality and effect of the signal transmission.

In addition, some manufacturers use a flat cable to electrically connect the internal terminal block of the connector of the connector, and the plurality of core wires of the flat cable are arranged in parallel according to the definition of the pin of the terminal group. Arrangement, which can facilitate the welding operation by matching the wire end of the core wire with the pin position of the terminal group, thereby improving the accuracy and yield of the manual alignment, reducing the labor and cost of the manufacturing, and avoiding Because the plurality of core wires are entangled to enhance the quality and effect of the signal transmission, since the connector socket of the general connector is covered with a shielding material made of a metal material, and the grounding wire and the shielding shell of the core wire are provided. The body forms a ground loop. Therefore, whether the multiple core wires of the circular or flat cable are soldered to the terminal group, the ground wire must be folded back and the high frequency signal lines of the other plurality of core wires by manual means. The low-frequency signal lines are separated to allow the core layer peeling of the outer core wire to be coated, and the subsequent soldering process, and the automatic wire bonding process cannot be automated.
