An electrical connector, especially the electrical connector used in high frequency communication, usually uses a metal housing to secure the insulating main body in the electrical connector. Consequently, the metal housing can shield the insulating main body and a plurality of electrical terminals accommodated in the insulating main body so as to reduce the effects of external electromagnetic interference (EMI) on the signals transmitted in the electrical connector.
Conventional electrical connector used in high frequency communication is usually provided with a metal housing, which covers one side and is not completely closed; consequently, the insulating main body cannot be securely fastened in the electrical connector. Moreover, when electronic components are butt connected to the electrical connector, additional fastening devices are usually required to provide good electrical conduction, leading to high cost and tedious operation.
Accordingly, it is necessary to design an electrical connector with a metal housing which can effectively secure the insulating main body accommodated therein and strengthen fastening for the electronic components connected to the electrical connector in order to overcome the drawback described above.
