A fitting groove 22 is formed between the flange 212 and the base portion 21, and a front end portion of the base portion 21 is vertically protruded to form a tongue 214. A plurality of terminal slots 215 are defined in the tongue plate 214, and the terminal slots 215 extend through the base portion 21, and a mounting hole 216 is formed on the upper surface of the latching block 211. The bottom wall of the terminal slot 215 defines an opening extending through the tongue plate 214. 217. Referring to the third to fifth figures, the conductive terminal 30 has an elongated shape, and has a contact portion 31, a terminal soldering leg 32, and the end of the contact portion 31 is bent obliquely downward to form a fixing portion 33. Referring to the third to fifth figures, the metal casing 40 has a casing bottom plate 41 opposite to the substrate 13. The casing bottom plate 41 is provided with a concave and convex sealing portion 42 corresponding to the locking hole 131, and the rear edge of the casing bottom plate 41 is bent. A folding portion 44 is defined in the folding portion, and a through hole 44 is defined in the interface between the locking portion 43 and the outer casing bottom plate 41. The opposite side edges of the outer casing bottom plate 41 are respectively bent and extended with a side wall 45, and the side wall 45 is away from the side edge of the outer casing bottom plate 41. Solder legs 46 extend outwardly. During installation, the conductive terminal 30 is firstly inserted into the insulative housing 20 from the mounting hole 216, and the contact portion 31 is fixed in the terminal slot 215 of the tongue plate 214 to expose the terminal soldering leg 32 to the insulative housing 20; 20, together with the conductive terminal 30, is inserted into the accommodating space 14 from the rear of the metal inner casing 10, and the rear end of the substrate 13 is engaged in the fitting groove 22, and the block 211 is sealingly engaged with the bayonet 112. At this time, the base 21 is A mating cavity 15 is formed between the tongue plate 214 and the metal inner casing 10 and is inserted into the mating connector. Finally, the metal casing 40 is sleeved on the metal inner casing 10 and the insulative body 20, and the metal casing 40 is covered with the metal inner casing 10. The two substrates 13 and the two side plates 12 are integrally welded to the metal inner casing 10, and the engaging portion 43 at the rear of the metal casing 40 is engaged with the card slot 213. As described above, the metal casing 40 of the water-repellent electrical connector 100 of the present invention includes a substrate 13 provided with a holding hole 131 of the metal-clad inner casing 10 of the M383228, and covers the holding hole 131 of the substrate 13 to prevent water from being removed from the substrate. The holding hole 131 flows into the PCB of the electrical connector to ensure the normal operation of the circuit; in addition, the metal casing 40 is in contact with the metal inner casing 10 to serve as a grounding function instead of the welding leg of the prior art metal casing. Therefore, the water is prevented from flowing from the gap between the soldering leg and the metal casing to the PCB board of the electrical connector, further waterproofing; and the metal casing 40 is provided with a concave convex at the corresponding holding hole 131. The blocking portion 42 encloses the holding hole 131, and the stopper 132 is received in the blocking portion 42, so that the metal casing 40 and the metal inner casing 10 are more closely matched, and the waterproof effect is better.
