A waterproof sleeve is detachably sleeved on the connection end of the female terminal and the male terminal. However, during connection, only the contact friction force between the waterproof sleeve and the male terminal and the female terminal is used to connect the male terminal and the female terminal. The connection strength is low, and the metal pins between the male terminal and the female terminal are prone to dislocation, and the metal pins are prone to deformation when forcibly inserted.

The plug-in component includes a plug-in block arranged on one side of the male terminal or the female terminal and a plug-in slot arranged on the other side and adapted to the plug-in block.

[0006] Further: A buckling structure is further arranged between the male terminal and the female terminal. The buckling structure includes a buckling block arranged on one side of the male terminal or the female terminal and a buckling slot arranged on the other side and adapted to the buckling block.

[0007] Further: The plug-in block is arranged on the male terminal, and the plug-in slot is arranged on the female terminal. An extension block is arranged in the female terminal. The conductive member is arranged inside the extension block. The plug-in block is arranged on the side of the extension block. A groove for inserting the extension block is further arranged in the female terminal. The plug-in slot is arranged on the side wall of the groove and communicates with the groove. The pin is arranged in the groove.

[0008] Further: The buckling block is arranged at the female terminal, the buckling groove is arranged at the male terminal, a deformable elastic block is arranged on the male terminal, and the buckling groove is formed on the elastic block.

[0009] Further: The elastic block is provided with a bent portion extending obliquely upward, and the buckling block is provided with a guiding inclined surface in contact with the bent portion.

[0010] The technical solution of the present utility model has the following advantages:

[0011] 1. For a wire harness plug-in structure provided by the present utility model, when the male terminal and the female terminal are connected, the plug-in block is first inserted into the plug-in slot for preliminary positioning, so that the insertion pin can automatically insert into the conductive part, thus avoiding the problem that the metal insertion pins between the male terminal and the female terminal are easily misaligned and the metal insertion pins are easily deformed when forced to insert.

[0012] 2. For a wire harness plug-in structure provided by the present utility model, after the male terminal and the female terminal are plugged in, to prevent the male terminal from disengaging from the female terminal, a buckling structure for locking the two is provided between the male terminal and the female terminal.
