[0024] refer to Figure 1 and Figure 2 A T-shaped block 17 is fixedly connected to the right side of the outer casing 1, and a T-shaped groove 18 that cooperates with the T-shaped block 17 is opened on the left side of the outer casing 1. A positioning protrusion 19 is fixedly connected to the rear of the right side of the outer casing 1, and a positioning hole 20 that cooperates with the positioning protrusion 19 is opened on the rear of the left side of the outer casing 1.

[0025] As a technical optimization of this utility model, by setting the T-shaped block 17 on the right side of the outer casing 1 to cooperate with the T-shaped groove 18 on the left side, and the positioning protrusion 19 on the right rear to cooperate with the positioning hole 20 on the left rear, when multiple branch terminals need to be combined for use, simply align the T-shaped block 17 and insert it into the T-shaped groove 18, and align the positioning protrusion 19 with the positioning hole 20 for positioning.

[0032] The working principle and usage process of this utility model are as follows: In use, the conductor base 2, as the core component, has excellent conductivity. The cable is connected to the conductor base 2 through the cable connection groove 3, and the busbar is connected to the conductor base 2 through the busbar insertion groove 4, thus allowing electrical energy from the cable or busbar to be conducted to the conductor base 2. The conductor base 2 is equipped with multiple branch slots 10. After a branch wire is inserted into a branch slot 10, it forms an electrical connection with the conductor base 2, thereby distributing the electrical energy from the conductor base 2 to each branch wire, achieving the branch wire function. The cable fixing bolt 6, busbar fixing bolt 8, and branch wire fixing bolt 12 respectively fix the cable, busbar, and branch wire, ensuring their connection with the conductor base 2. The connection between them is tight and stable, reducing contact resistance and ensuring the efficiency and stability of power transmission. When it is necessary to connect the busbar, remove the baffle 22 and insert the busbar from the busbar input slot 21 into the busbar plug slot 4. Through the second operating holes 15 on the left and right sides of the top front of the top of the top cover 13, use a tool to tighten the busbar fixing bolt 8 to move the clamping conductor plate 9 downward and press the busbar tightly onto the conductor seat 2. Insert the branch line into the branch line slot 10 behind the surface of the conductor seat 2. Through the third operating hole 16 behind the top of the top of the top cover 13, use a tool to screw the branch line fixing bolt 12 into the branch line fixing slot 11 to ensure that the branch line is reliably connected to the conductor seat 2. Similarly, cables can be connected.
