[0002] As we all know, people can't do without data cables in their lives now. The data cables are equipped with connectors that match the input (output) devices at both ends of the wire harness to transmit data such as digital video, high-resolution TV, and images. For serial flow, the connector generally adopts a plug-in type, and the two ends of the wire bundle are respectively connected to the inserts (slots) arranged in parallel on the connector. Shielding devices and materials are provided on the wire bundle and the connector to prevent interference. , with the development of science and technology, people have invented low-voltage differential signal transmission technology, which has the advantages of fast signal transmission speed, low power consumption, and low noise. The core wire conductor layer and the connector are composed. The core wire conductor layer includes a plurality of metal core wires arranged in parallel with each other. Since there is no national standard for the connector at present, there are many connectors of various structures. The general structure is: flexible cable There is a cable contact at the end of the upper surface of the flexible cable, and a connecting seat is provided on the lower surface of the flexible cable. The flexible cable is fixed on the connecting seat through a pressure plate provided on the upper surface. The connector does not have a positioning hook device, so The deficiencies of the existing coilable flexible cable are that the characteristic impedance of the cable cannot be adjusted, and the scope of application is small; the second is that there is no shielding on the cable, which makes the overall anti-interference ability poor; The connection between the connector and the corresponding socket is unreliable and unstable, and the electrical connection between the contacts of the connector and the socket cannot be ensured, resulting in loss, loss, deformation or distortion of the transmission signal, which in turn affects the stability of the system operation. Fourth, There is no shielding on the connector, making it less resistant to interference
