The insulative housing is provided with a receiving space for receiving the docking connector and a bottom wall facing the external circuit board. The receiving space is formed with an opening through a side surface adjacent to the mating surface, and the two sides of the opening form a block on the inner side of the receiving space. After the docking connector is fully inserted into the receiving space, it is engaged with the card block to ensure the close cooperation between the docking connector and the electrical connector. The plurality of conductive terminals penetrate the bottom wall and are soldered to the external circuit board. In the injection molding process, the above-mentioned blocks are formed, and the mold core can only be released from the bottom wall of the insulating body. Therefore, it is necessary to provide a through hole corresponding to the block on the bottom wall of the insulating body. Thus, in the process of soldering the conductive terminals, high-temperature gas enters the inside of the electrical connector from the through-hole, resulting in a risk of soldering of the internally soldered electronic components. [0003] It is indeed necessary to design an improved electrical connector to overcome the deficiencies of the prior art.

The first-bump 123 cooperates with the fastening hole 33, and the second & block 216 and the buckle The hole 33 fits to achieve a better holding effect. The rear wall (4) is punched with a resilient piece 32 at the corresponding notch 215. The elastic piece 321 is folded inwardly and abuts against the grounding leg 251 of the capacitor 25 to achieve the purpose of grounding the capacitor 25. In addition, the shielding shell 3 is further provided with an elastic portion that is fastened to the recess 131 of the insulating body, so that the holding effect of the insulating body i and the shielding shell 3 can be further enhanced. The dustproof cover 5 includes a horizontally extending body. The portion 51, the extension person receiving space (4), the elastic arm 52 and the holding block clamped between the elastic arms 52. Dust insertion insert form No. A0101 » r ^ When the work room li is in the 'clamp block 53' is held by the guide of the elastic portion 34 in the groove 131' and this (four) 'elastic f 52 is changed to the side wall 13 The inner surface 'prevents the dust cover 5 from accidentally falling off. Thus, in the case where the electrical connector 100 is not used, the dust cover 5 can be prevented from entering the electrical connector by the dust cover 5, and the internal 'ensures that the electrical connector 1 is connected to the terminal 24 with good electrical conductivity; if it is needed, , the dust cover 5 can be easily pulled out.
