[0041] Working principle: when two or more terminals need to be installed, the tongue 203 on the left side of the terminal 1 slides into the gap between the two limiting pieces 2024 on the right side of the terminal 1. With seamless contact between the two, the spring tip 204 is extruded by the limiting piece 2024 and retracts inside the tongue 203, making it possible for the tongue 203 to move between the two limiting pieces 2024. When the tongue 203 moves and brings the spring tip 204 to the position of the insertion hole 10 on the limiting piece 2024, the spring tip 204 is ejected outward under the action of the internal spring force and is buckled with the insertion hole 10, realizing the fixation of the tongue 203 and the limiting piece 2024, so that two different terminals 1 can be connected into a whole in the horizontal direction. At the same time, the wedge-shaped buckle 2021 is buckled with the wedge-shaped groove 201, and the spring piece 2022 tightly fits with the wedge-shaped groove 201, and the spring tip 205 is inserted into the corresponding hole in the wedge-shaped buckle 2021, thereby ensuring the stability of the overall connection. In the vertical direction, when the two terminals 1 are vertically attached to each other, the clamping block 208 is inserted into the clamping groove 206, the clamping block 208 moves in the same direction and spreads the two metal clamps 207. When a certain distance is moved, the end of the metal clamp 207 is embedded in the recess hole on both sides of the clamping block 208, completing the fixation of the two terminals 1. When the connection needs to be released, a force opposite to the spring force of the spring tip 204 is applied from the insertion hole 10, and the oval bolt 2023 is rotated to break the contact between the spring piece 2022 and the wedge-shaped buckle 2021, so that the wedge-shaped buckle 2021 can be separated from the wedge-shaped groove 201, and the metal clamp 207 is loosened. The connection in the horizontal and vertical directions can be contacted. This set of mechanism realizes the modular assembly of different terminals with a limited number of connection structures, without the need for using too many additional tools, with the convenience of installation and disassembly, without the need for adding too many redundant structures, which is conducive to saving the internal space of the equipment and facilitating the maintenance of the equipment in the later period.

[0042] When the terminal 1 and the terminal 4 are connected, the top cover 303 is pushed forward, and the top cover 303 slides on the sliding groove 301 under the connection of the connecting rod 304 and the support column 302. With the movement of the top cover 303, the middle extrusion connecting strip 3051 moves downward, the locking groove 3052 presses the connection between the two wires, and the connection between the two is reinforced. At the same time, the spring tip 3053 is ejected outward to prevent abnormal displacement of the top cover 303. When the connection of the two terminals needs to be released, press the spring tip 3053 to move the top cover 303 and the connecting rod 304 in the opposite direction to reset.
