[0002] A relay is a device used for automated electrical switching. It can control the on and off of a circuit.

[0023] This specific embodiment is a relay quick installation structure, and its structural diagram is as follows Figure 1-Figure 5 As shown, it includes a relay body 1, which is provided with a plurality of wiring slots 2, in which a connecting cylinder 3 is assembled, and a screw hole 15 is provided on the bottom surface of the wiring slot 2. The bottom end of the connecting cylinder 3 is fixedly connected to a screw rod 14, which is threadedly connected to the screw hole 15. A quick fixing part is provided on the inside of the connecting cylinder 3, and an annular groove 7 is provided on the top end surface of the connecting cylinder 3. A reset component is provided in the annular groove 7.

[0024] Specifically, the connecting tube 3 adopts a connection method of a screw rod 14 and a screw hole 15. Even if the screw connection method needs to be replaced later, it will not cause any impact, and the flexibility is high. In addition, if the ring-shaped terminal needs to be fixed, the ring-shaped terminal can be directly put on the screw rod 14 and tightened in the screw hole 15 to fix it.

[0025] like Figure 3 and Figure 4 As shown, the quick fixing part includes several conductive plates 4 arranged in the inner cavity of the connecting tube 3. The conductive plates 4 are arranged in an arc shape. The side walls of the conductive plates 4 are fixedly connected with several metal elastic plates 5. The other end of the metal elastic plate 5 is fixedly connected to the inner wall of the connecting tube 3. The metal elastic plate 5 is arranged in a V shape.

[0026] Among them, the connecting tube 3, the conductive plate 4 and the metal elastic plate 5 are all made of conductive materials. After the terminal is fixed to them, the current can be directly connected to the relay through the screw 14; and the use of a quick connection method can reduce a lot of wiring time, which is more convenient and quick.

[0027] like Figure 4 As shown, the top end surfaces of the conductive plates 4 are all expanded outwards to increase the insertion surface of the terminal blocks, making it easier for users to quickly connect the terminals and guiding the terminals.

[0028] like Figure 3 As shown, the inner wall of the conductive plate 4 is fixedly connected to a plurality of protrusions 6, which are arranged at a downward angle. After the terminal is crimped with a wire crimping pliers, the terminal will have more recessed areas than the surface. When the terminal is inserted into the inner side of the conductive plate 4, the protrusions 6 can fill the recessed areas, further strengthening the terminal.

[0029] like Figure 3 and Figure 5As shown, the reset assembly includes a first annular plate 9 and a second annular plate 11 arranged in the inner cavity of the annular groove 7, the second annular plate 11 is flush with the end surface of the connecting tube 3, a number of connecting rods 10 are fixedly connected between the first annular plate 9 and the second annular plate 11, a number of springs 8 are fixedly connected between the annular groove 7 and the first annular plate 9, a number of pull ropes 12 are fixedly connected to the inner wall of the first annular plate 9, a number of through holes 13 are opened on the side wall of the annular groove 7, and the other end of the pull rope 12 passes through the through hole 13 and is fixedly connected to the conductive plate 4.

[0030] By setting up a reset component, the conductive plate 4 can be quickly opened outward, making it easy to remove the terminal. It has a simple structure and is easy to operate. It plays an important role in replacing the wires in the later stage, avoiding the probability of damaging the terminal by pulling the wires hard.

[0031] like Figure 2 and Figure 3 As shown, an insulating pad 16 is fixedly connected to the side wall of the connecting tube 3. By providing the insulating pad 16, the outside of the connecting tube 3 can be ensured to be in a safe state, preventing the wiring personnel from accidentally touching it during live work, and further improving the safety of wiring.

[0032] Working principle: When the relay body 1 needs to be wired, first press the wire end with a wire crimping pliers to tighten the terminal, and then insert the terminal directly between the conductive plates 4. The conductive plate 4 is squeezed outward by the terminal and squeezes the metal elastic plate 5. The resilience of the metal elastic plate 5 is used to apply squeezing force to the terminal to achieve the purpose of fixation. When the wire needs to be removed, use tweezers, screwdrivers and other tools to press down the second annular plate 11. The second annular plate 11 drives the first annular plate 9 to move downward through the connecting rod 10. The first annular plate 9 pulls the pull rope 12 to move downward. At the same time, the spring 8 is compressed, and the pull rope 12 expands the conductive plate 4 outward, loosening the fixation on the terminal, making it easy to remove the wire and achieving the purpose of quick installation and disassembly.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
