[0041] Working principle: when installing the terminal 4, first, the limiting block 6 on the front and rear sides of the bottom of the terminal 4 is accurately aligned with the corresponding groove 8 on the connecting strip 3, which lays the foundation for subsequent installation and ensures that the components can be correctly matched. Then, the terminal 4 is moved downward. When the limiting block 6 contacts the edge of the groove 8, the bottom of the limiting block 6 is rounded, so that the limiting block 6 can smoothly slide into the reserved groove 5 and squeeze the spring 7 during the pressing process of the terminal 4. With the continuous downward movement of the terminal 4, when the bottom of the terminal 4 is attached to the top of the guide rail 1, the limiting block 6 is out of the squeezing state with the groove 8. Under the elastic force of the spring 7, the limiting block 6 quickly slides outward until its top tightly attaches to the bottom of the connecting strip 3, effectively limiting the movement of the terminal 4 in the vertical direction and preventing it from being pulled out upward due to vibration and other external forces. The width of the groove 8 is designed to be equal to that of the terminal 4, which limits the movement of the terminal 4 in the horizontal direction.

[0042] And when preparing to install the wire, the pressing block 205 can be pressed into the pressing groove 204, and at this time the connecting rod 206 connected with the pressing block 205 will move synchronously, because the adjacent end of the multiple connecting rods 206 is fixedly connected with the corresponding clamping piece 203, so the movement of the connecting rod 206 will push the clamping piece 203, and then squeeze the spring 202, so that the space between the clamping piece 203 and the inner wall of the wire insertion hole 9 is left for the installation of the wire guide, then the end of the wire is inserted into the wire insertion hole 9, and in the insertion process, the guide ring 201 guides the end of the wire to smoothly enter the area between the clamping piece 203 and the wire insertion hole 9, then the pressing block 205 is released, at this time the compressed spring 202 begins to release the elastic potential energy, under the action of the spring 202, the clamping piece 203 is squeezed and moves towards the wire, with the movement of the clamping piece 203, the space between the clamping piece 203 and the inner wall of the wire insertion hole 9 gradually decreases, and finally tightly clamps the wire.
