[0004] To this end, the utility model provides a double-strand wire terminal, including a terminal body, a docking portion for docking with a conductive element, and a fixing portion for fixing the terminal, the fixing portion including a first buckling portion for buckling with an insulating shell of the wire and a second buckling portion for buckling with a wire core, the height of the first buckling portion being higher than the height of the second buckling portion.

[0005] Further: the first buckle part has a first slot, the second buckle part has a second slot, the docking part has a third slot, the first slot and the second slot are arranged in the horizontal direction, and the third slot is arranged in the longitudinal direction.

[0006] Further: the docking portion includes a docking piece and buckled bending pieces arranged on both sides of the docking piece and capable of bending from both sides to the middle, and the docking piece is provided with an elastic piece for docking with a conductive element.

[0007] Further: the first snap-on portion includes a first snap-on piece that is relatively arranged, the bottom of the first snap-on piece is connected to the terminal body, and the other end can be bent from both sides to the middle, the second snap-on portion also includes a second snap-on piece that is relatively arranged, the bottom of the second snap-on piece is connected to the terminal body, and the other end can be bent from both sides to the middle, and the height of the first snap-on piece is higher than the height of the second snap-on piece.

[0009] The technical solution of the utility model has the following advantages:

[0010] 1. The utility model provides a double-strand wire terminal, in which the wires have a wrapped portion wrapped by an insulating shell and an exposed portion not wrapped by the insulating shell, and the height of the first buckle portion is higher than that of the second buckle portion. When installing the wires, the two guides are stacked up and down and then placed in the first buckle portion (the width of the first buckle portion can only accommodate one wire, while the height can accommodate two wires), so that the first buckle portion is bent to tightly buckle the insulating shell, and then the second buckle portion is bent and buckled onto the wire core. Through the arrangement of the first buckle portion and the second buckle portion, the double locking of the wire by the terminal can be achieved, and the first buckle portion and the second buckle portion can be simultaneously applicable to the fixing of single-strand wires, thereby expanding the scope of use.
