[0003] HDMI is a transmission interface developed for multimedia audio-visual equipment. It is one of the most advanced digital interface standards in the world. In addition to transmitting image data, it can also transmit up to 8-channel audio signals at the same time. It can transmit audio-visual signals at the same time without multiple wires to connect, which greatly simplifies the installation of audio-visual systems. There is no doubt that HDMI connectors will be a major trend in the future development of the audio-visual industry. HDMI connectors generally consist of HDMI interfaces and The connecting wire is composed of the traditional HDMI interface also includes a printed circuit board, the printed circuit board is provided with via holes, and the terminals are arranged on both sides of the printed circuit board, so that during the assembly process of the traditional HDMI connector, Each signal line needs to be manually arranged and then welded. Not only the appearance and function of the welding are not good, but also the labor cost is greatly increased, which is not conducive to the promotion and application of the product.

Abstract

The invention provides a connecting structure of a cable and a PCB, a plug assembly adopting the connecting structure and a preparation method of the plug assembly. The cable comprises a plurality ofwires, the outer side of each wire is sequentially wrapped by an insulator, a shielding layer and an insulating sheath from inside to outside, the surface of the PCB is provided with a grounding layerand a row of first golden fingers, the grounding layer is provided with a plurality of second golden fingers, the tail end of each wire is connected with a corresponding first golden finger, the shielding layer is fixed to the grounding layer through UV conductive adhesive, and meanwhile the shielding layer is electrically connected with the grounding layer. According to the invention, the shielding layer of the cable and the grounding layer of the PCB are fixedly connected and electrically connected by adopting the ultraviolet curing principle of the UV conductive adhesive, a traditional tinsoldering process is replaced, and the shielding layer and the grounding layer can be fixedly connected only by ultraviolet irradiation.
