The part is in contact with the shielding shell 11 to provide the effect of conducting and grounding the buckle spring.

Referring to Fig. 2 and Fig. 4, in this embodiment, the socket electrical connector 100 is further provided with a plurality of conductive sheets, the plurality of conductive sheets are long strips of metal material, the upper conductive sheet is arranged above the base 21, and the following The square conductive sheet is arranged under the base 21 . When the electrical plug connector is inserted into the electrical receptacle connector 100, the front end of the shielding shell of the electrical plug connector will touch the conductive sheet, so that the shielding shell of the electrical plug connector and the electrical receptacle connector 100 The shielding shell 11 is effectively conducted through the conductive sheet, thereby reducing the problem of Electromagnetic Interference (EMI).

Through the shielding shell and the rear side of the insulating body, there is a filling groove structure and a channel structure, and the filling groove structure is used for filling a liquid-like sealing body, and the sealing body overflows from the filling groove structure into the channel structure so that the rear side of the insulating body is covered with a sealing body , when the sealing body is a liquid, it is dried and formed into a hardened waterproof rubber block structure, so that the shielding shell and the rear side of the insulating body are closed, and water vapor cannot penetrate into the accommodating slot from the front side of the shielding shell to the shielding shell. rear side. Moreover, the stop block is arranged at the corner between the top of the rear side plate and the base, the stop block, the base and the inner wall of the main body jointly define the filling groove structure, and then the filling groove structure can accommodate the space of the sealing body due to the stop. Block structure can be reduced to reduce the amount of sealing body and also achieve the effect of covering and waterproofing.

In addition, the plurality of upper-row flat-plate terminals and the plurality of lower-row flat-plate terminals of the socket electrical connector are upside down, and the arrangement of the plurality of contact segments in the upper row is opposite to the arrangement of the plurality of contact segments in the lower row, providing a plug electrical connector When it is plugged into the socket electrical connector in the forward direction, the terminals of the plug electrical connector can be connected with the plurality of contact segments on the upper row, and when the plug electrical connector is plugged into the socket electrical connector in reverse, the plug is electrically connected The terminals of the device can also be connected to the plurality of contact segments in the lower row, and the socket electrical connector has the function of not restricting the forward or reverse insertion of the plug electrical connector.
