Description

Manufacturing method of electrical connector

【Technical field】

The invention relates to a manufacturing method of an electrical connector, in particular to a manufacturing method of an electrical connector including a shielding shell and an insulating body.

【Background technique】

With the rapid development of information technology, the functions of electrical connectors are increasingly enhanced and improved. The rapid increase in the requirements for information storage and the acceleration of transmission speed have caused great changes in the interface interface, and with the development of electronic products towards miniaturization, the size of the connector is also reduced, so that the terminal arrangement will be closer. At the same time, the signal transmission is seriously affected by electromagnetic interference. For electrical connectors with precise structures, small electromagnetic interference generated by other external electronic devices is likely to have a greater impact on telecommunication transmission. In order to prevent the signal passing through the telecommunication transmission from radiating to other electronic devices, or the noise from other signal sources entering, the periphery of the docking part of the electrical connector, especially the high-density electrical connector, is generally covered with a metal shielding shell to prevent electromagnetic interference. , as shown in US Patent Nos. 6,322,396 and 6,371,809. However, the shielding shells disclosed in these prior art are assembled on the periphery of the insulating body. In practical applications, the shielding shells may fall off or become loose due to external force, so that the electrical connectors cannot be effectively shielded. Moreover, the above-mentioned shielding shells are made individually, which is not conducive to the automatic operation of the subsequent process and is not conducive to improving production efficiency.
