[0010] In a possible design, a plastic surface cover is snap-fitted onto the top of the plastic middle cover, and a hole is formed on the top of the plastic surface cover for the row of pins to pass through.

[0011] In a possible design, curved plates are fixedly installed on both sides of the plastic middle cover, and mounting holes are provided in the two curved plates. The two curved plates can facilitate taking the plastic middle cover and can be easily installed and fixed with external equipment.

[0012] In a possible design, a concave surface for fitting the wire is provided between the plastic middle cover and the plastic back cover.

[0013] In a possible design, the ends of the plurality of first metal screws are pointed, which can better pierce the wire.

[0014] In the present application, when in use, the user can apply waterproof glue to the wire and then clamp it between the plastic middle cover and the plastic back cover for buckling and fixing. Then the PCB board and the pin header can be installed in the plastic middle cover, and the PCB board can be fixed with multiple first metal screws. While fixing, the end of the first metal screw pierces the wire so that the first metal screw is in full contact with the conductor in the wire. The fixing of multiple first metal screws is completed in sequence, and then the plastic surface cover can be ultrasonically welded to the top of the plastic middle cover to cover the PCB board and multiple first metal screws.

[0015] In the utility model, the three-way connector is fixed to the PCB board by using the first metal screw, and the fixing operation is simple. The wire can be pierced while fixing, and the conductor is directly connected without the need for additional wire welding, which can improve production efficiency and product stability.

[0016] In the utility model, the three-way connector can fix the connected wires by providing a positioning column, thereby preventing the wires from moving when being pulled, and further preventing the multiple first metal screws that pierce the wires from causing more damage to the wires;

[0017] In the utility model, the three-way connector does not require additional welding wires during production. When in use, the wires are directly pierced with metal screws to complete the connection, which can improve production efficiency and product stability. At the same time, the two ends of the connected wires can be fixed to avoid movement when the wires are pulled, thereby preventing multiple metal screws that pierce the wires from causing more damage to the wires.
