Description

Solder pin electromagnetic shielding reinforced female electrical connector

The present invention relates to the technical field of an electrical connector, and in particular to a female-end electrical connector with enhanced electromagnetic shielding of solder joints that enhances the electromagnetic shielding effect of the solder joints.

Electrical connectors are used to transmit electronic signals between electronic devices or electronic modules. Therefore, electrical connectors serve as interfaces for electronic device signal transmission or device connection. Currently, the most commonly used electrical connectors in electronic devices are Universal Serial Bus (USB) electrical connectors. In addition to the commonly used USB type A, the most commonly used USB electrical connector is the USB type C electrical connector.

The existing USB type C electrical connector, such as that disclosed in Chinese patent CN212062763U, has a metal partition between the upper and lower terminals to form an electromagnetic shield between the upper and lower terminals. However, when the welding parts of all the terminals are arranged in a row, only the welding part of the ground terminal can produce an electromagnetic shielding effect between the high-frequency signal terminal and the outside or between the high-frequency signal terminal and the conventional signal terminal. Since the width of the welding part of the ground terminal is limited, the electromagnetic shielding effect it produces is also limited, resulting in poor electromagnetic shielding, thus causing crosstalk or signal distortion problems.

In view of this, the purpose of the present invention is to provide a female electrical connector with enhanced electromagnetic shielding of solder pins, which solves the problem of poor electromagnetic shielding effect of the soldering part of the terminal in the prior art.
