An extension block 61 is provided at the bend to improve the stability of the connection between the male terminal 60 and the female housing 40, and to a certain extent, increase the stability of the structure. The welding portion has a welding joint 62 to avoid excessive soldering when welding the male terminal 60 to the PCB board 70. The end of the reinforcement 50 that welds to the PCB board 70 has a notch 51 to increase the welding strength. In an optional embodiment, as... Figure 13-14 As shown, during connector installation, the reinforcement 50 and male terminal 60 need to be soldered onto the PCB board 70, and then the reinforcement 50 and female housing 40 are snapped together. At the same time, the female terminal is inserted into the female terminal receiving cavity 29, so that the first anti-locking member 23 pre-locks the female terminal 80. The positioning auxiliary member 30 is inserted into the male housing 20. First, the primary locking buckle 31 moves in the primary locking groove 25 to pre-lock the positioning auxiliary member 30. Then, the positioning auxiliary member 30 continues to move relative to the male housing 20, so that the secondary locking buckle 32 is snapped into the secondary locking groove 26. Subsequently, after the male housing 20 is inserted into the female housing 40, the secondary locking 10 is inserted between the male housing 20 and the female housing 40, cooperating with the first and second locking members to realize the secondary snap-fit ​​connection between the male housing 20 and the female housing 40.
