It should be noted that the tail portion 33 does not extend to the harness groove 213 and the shallow groove 215, and is designed to prevent the terminal tail portion 33 and the core wire of the cable 4 from being welded by an automatic welding machine (mechanical arm). Damage to the harness groove 213, etc.; then, assembled together The partition plate 2 and the terminal 3 are assembled together with the terminal body 3, and the two notches 221 of the partition plate 2 are respectively matched with the positioning blocks 141 of the insulative housing 1, and the abutting portion 31 and the intermediate bending portion 32 of the terminal 3 are respectively The terminal groove 1321, 1331 of the insulative housing 1 is received and held, and the abutting portion 31 is exposed in the receiving space of the insulative housing 1; then, the cable 4 is assembled to the partition 2, the first group The cable 41 is fixed on the shallow slot 215, the second set of cables 42 are placed on the wire harness slot 213 and fixed thereto, one end surface of the second group cable 42 abuts against the shutter portion 22, and the second The core wire of the group cable 42 is pressed against the tail portion 33 of the terminal 3. When the soldering operation between the terminal 3 and the cable 4 is performed, since the cable 4 is fixed to the harness groove 213, and the core of the cable 4 is pressed against the tail portion 33 of the terminal 3, the terminal 3 is The cable 4 can be automatically soldered, the mechanical arm carries solder, and the tin is soldered to the overlapping area of the core wire of the cable and the terminal tail 33 to solder the terminal 3 and the cable 4, and the welding quality is relatively stable, and the product is improved. The production efficiency, less bad rate, meet the needs of modern production. After the above-mentioned welding process is completed, a cover body 5 is coated on the periphery of the insulating body 1, the separator 2 and the terminal 3 by using an overmolding technique, and the cover body 5 is covered on the insulating body. The rear end surface 52 of the cover body 5 is formed with a stress relief structure (Strain Relief) 521, which prevents the first group of cables 41 from being hardened by the tin after the tin soldering, thereby causing the first group of cables. 41 is prone to breakage problems. Further, the side ends 53 of the cover 5 are formed with a hand groove 531 for providing an extraction force when the electrical connector 100 is pulled out from the docking connector (not shown).
