A typical electrical connector is soldered to a circuit board, and its connection terminal is in contact with the contact end of the circuit board through the circuit layout to form an electrical connection. However, in some applications, the electrical connector is fixed as another Circuit components, such as the use of fixed flexible cables. Therefore, the electrical connector is between the flexible cable and the printed circuit board, and is used as an electrical signal. The electrical connector generally used for fixing a flexible cable has a structure mainly comprising an insulating body, a plurality of conductive terminals and an upper cover. The upper cover can be rotated and moved relative to the insulating body to open and close. When the upper cover is opened, the upper cover can be opened. The flexible cable is inserted into the insulative housing. When the upper cover is closed, the flexible cable can be electrically connected to the conductive terminal and fixed in the insulating body. 3 M397084 However, the electrical connector used to fix the flexible cable does not have other auxiliary structures to reduce electromagnetic interference (EMI), so the electrical signal transmitted in the electrical connector is easily affected by the external environment. As a result, the noise is too large, which in turn affects the transmission of electrical signals, resulting in customer complaints. [New content] The structure of the conventional electrical connector is not effective in preventing electromagnetic wave interference, and the electrical signal of the electrical connector is easily affected by external electromagnetic wave interference, which makes the transmission effect of the electrical signal worse, which leads to the generation of customer complaints.
