[0003] For the prior art related to this case, you can refer to an electrical connector disclosed in Taiwan Patent No. M484822, which includes an insulating body, two sets of conductive terminals fixed in the insulating body, and a metal sheet between the two sets of conductive terminals. And a metal shell that wraps the insulating body. The metal shell has electromagnetic shielding effect, so that the electromagnetic wave of the signal transmitted by the electrical connector does not interfere with the external electromagnetic wave. However, the metal shell is a single-layer electromagnetic shielding structure. The shielding effect of electromagnetic waves is not perfect, and the structural strength of the metal shell is slightly lower, which reduces the high-frequency signal transmission performance of the electrical connector and shortens the service life of the electrical connector

The invention relates to an electric connector. The electric connector comprises an insulating body, terminal modules, an inner metal shell and an outer metal shell, wherein the terminal modules are assembled in the insulating body, and the inner metal shell and the outer metal shell coat the insulating body. The insulating body comprises a top, a bottom, two side portions and a butt joint hole, wherein the two side portions are connected with the top and the bottom, and the butt joint hole is formed among the top, the bottom and the two side portions. The inner metal shell is of a one-piece structure and comprises a main frame sleeving the insulating body, the main frame surrounds the insulating body completely, and the outer metal shell of a lengthwise-tube-shaped structure sleeves the inner metal shell and contacts with the same. By the aid of a double-layer electromagnetic screen shielding structure formed by the inner metal shell and the outer metal shell, a shielding effect for external electromagnetic waves is improved, and the high-frequency signal transmission performance of the electric connector is improved.
Description
technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector with high frequency performance. Background technique [0002] With the fast pace of people's life and the increasing demand for fast transmission of large amounts of data, the signal transmission specifications of corresponding electronic equipment must also be improved, and the electrical connectors on electronic equipment must increase the frequency of transmission signals to cope. Since high-frequency signals are easily interfered by surrounding environmental variables and cause poor signals, the design and manufacturing standards of electrical connectors for transmitting high-frequency signals have also increased accordingly. [0003] For the prior art related to this case, you can refer to an electrical connector disclosed in Taiwan Patent No. M484822, which includes an insulating body, two sets of conductive terminals fixed in the insulating body, and a me...
