Description

Electric connector structure Technical Field The invention relates to an electric connector structure, in particular to an electric connector, a wire frame group formed outside a plurality of cables can provide a fixed distance between a front cable and a rear cable, so as to reduce the coupling effect between adjacent cables, and electromagnetic waves generated when the plurality of cables transmit high-frequency signals are absorbed by a grounding sheet, thereby greatly reducing the electromagnetic interference effect, and the grounding sheet is in a flat plate-shaped structure so as to form good current conduction and difficult heat accumulation. Background To maintain optimal electrical characteristics in the cable coupled to the electronic device, it is necessary to avoid the discontinuity of the system impedance to maintain a fixed impedance, and to provide an electrical connector that creates a discontinuity impedance at the interface between the cable and the electronic device, further creating Insertion Loss (Insertion Loss) with reduced signal strength, and reflection Loss (Return Loss) where the signal is reflected back to the signal source. As mentioned above, the insertion loss is related to the length of the cable and the number of connection points, and the loss is greater as the cable is longer or the connection points are more. The reflection loss refers to the energy reflected back to the signal source due to impedance mismatch or discontinuity in the signal transmission process in the conductor, and these parameters have important effects on the transmission speed, integrity and reliability of the high-frequency signal. In addition, near-End Crosstalk (NEXT) and Far-End Crosstalk (FEXT) are two common problems in high frequency characteristics. Where near-end crosstalk refers to interference signals coupled to adjacent cables near the signal source and affecting signal integrity. Far-end crosstalk refers to interference signals coupled to adjacent cables and causing signal distortion near the signal receiving end. The effect of far-end crosstalk is typically greater than near-end crosstalk because it accumulates interference signal energy over the length of the cable. As a result of the foregoing problems associated with the coupling of the cable to the electrical connector, the industry is required to optimize the structure of the electrical connector.
