In particular, the two sides of the rear cover 114 are provided with fixing pieces 1141. When the electrical socket connector 100 is welded on the circuit board, the joints between the first welding sections 316 and the circuit board are covered with solder, and the rear cover 114 is in an open state. It is provided to check whether each first welding segment 316 is in contact with each contact point and whether each solder is separated from each other to avoid a short circuit (as shown in FIG. 10 ). When each first welding segment 316 is in contact with each contact point, the The rear cover 114 is closed so that the rear cover 114 covers the rear side of the accommodating groove 112, and the fixing pieces 1141 on both sides of the rear cover 114 are firmly fastened on both sides of the shielding shell 11, so that the rear cover 114 is opened and The closing method is convenient for inspecting the welding status, and rework can be carried out quickly if a welding error is found.

The utility model is a socket electrical connector of a raised type, the length of each first flat terminal is lengthened and the length distance is longer than that of the general terminal, and the terminal foot positioning seat is formed by the first horizontal (straight type) first flat terminal. , and then install each first flat terminal and terminal foot positioning seat on the base and the tongue plate, thereby fixing, positioning and protecting each first flat terminal with a long distance between the base and the tongue plate, which can effectively Avoid affecting the insert-molding process and increasing the difficulty of processing due to the lengthening of the first flat terminals.

Moreover, each first welding section of each first flat terminal is fixed through the terminal foot positioning seat, and when each first flat terminal is bent, each first welding section is bent once by using the terminal foot positioning seat, that is The angle between each first contact section and each first welding section can meet the angle of a solderable circuit board, which can improve the convenience of bending and the function of accurate bending and positioning of each first welding section.
