[0019] Specifically, the V-shaped limiting block 10 is nested in the V-shaped limiting groove 7 to facilitate fixing the wiring terminal 6 .
[0020] The top of the V-shaped limit block 10 and the end of the push block 5 are both provided with an inclined surface 11, and the two inclined surfaces 11 are connected.

[0022] Specifically, the slider 17 is pushed upward by the reset spring 18, and the upward movement of the slider 17 drives the V-shaped limit block 10 to move upward, so that the V-shaped limit block 10 is separated from the V-shaped limit groove 7, which is convenient for pulling out the wiring terminal 6.
[0023] The top of the cavity 8 is fixedly connected with a connecting shaft 14 , the top of the pawl 13 is nested with the connecting shaft 14 , and a torsion spring is fixedly installed at the connection between the pawl 13 and the connecting shaft 14 , and a through hole 9 is opened on the other side of the inner wall of the cavity 8 .

When the terminal head 6 is connected to the terminal row 1, the terminal head 6 is first inserted into the terminal hole 4, and then the push block 5 located at the top of the terminal hole 4 is manually pushed. The push block 5 contacts the inclined surface 11 of the V-shaped limit block 10, and the V-shaped limit block 10 is pushed and squeezed downward by the push block 5, so that the bottom end of the V-shaped limit block 10 and the top end of the terminal head 6 are embedded with the V-shaped limit groove 7, so that the terminal head 6 is fixed inside the terminal hole 4. When the push block 5 is pushed to the set position, the ratchet 13 and the reverse groove 12 are embedded and fixed to complete the connection between the terminal head 6 and the terminal hole 4, replacing the traditional method of fixing the terminal head 6 by screws, thereby improving the convenience of installing the terminal;
[0028] When the terminal 6 needs to be pulled out, first, it is necessary to manually insert a pin into the through hole 9 to push the pawl 13 to separate from the inverted groove 12. At this time, the reset spring 18 pushes the slider 17 to move upward, and the upward movement of the slider 17 drives the V-shaped limit block 10 to move upward. The V-shaped limit block 10 moves upward and pushes the push block 5 to reset together with the terminal 6. Then, the terminal 6 is manually pulled out to complete the disassembly of the terminal 6.
