[0002] Solid-state relays are contactless switches composed of microelectronic circuits, discrete electronic devices, and power electronic devices. Solid-state relays often require installation during use, therefore, a vibration-resistant solid-state relay that is easy to install and remove is needed.

[0003] Patent CN221805397U discloses a vibration-resistant solid-state relay that is easy to install and disassemble. By adding installation and disassembly components, the installation and disassembly steps of the solid-state relay body are greatly simplified, making it easier for staff to quickly install and disassemble the solid-state relay body, speeding up the installation and disassembly efficiency, and making it easy to use.

[0004] However, the mounting and dismounting components on the aforementioned solid-state relays still present certain problems in use. On the one hand, the mounting and dismounting components only provide two-point fixation to the relay body, resulting in poor installation stability. On the other hand, the reset rods of the mounting components are located on both sides of the mounting base. When multiple relays are installed side by side, the maintenance space is limited, making it impossible to operate the reset rods, or requiring sufficient space to be left for the operation of the reset rods during relay installation, which is not conducive to space utilization.

[0005] Based on this, a solid-state relay structure that is easy to install and disassemble is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] The above embodiment discloses a solid-state relay structure that is easy to install and disassemble. When installing the relay body 100, the drive rod 403 is moved along the first arc-shaped groove 207 to drive the disc 401 to rotate. At the same time, the first guide rod 302 is moved along the first guide groove 203 through the second arc-shaped sliding groove 402 on the disc 401, so that the locking block 301 is put into the second mounting groove 202. Then, the relay body 100 is installed in the first mounting groove 201. Then, the drive rod 403 is released, and the locking block 301 is moved outward along the second mounting groove 202 by the action of the first spring 304 until the locking block is engaged. 301 is inserted into the slot 105 on the relay body 100, and finally the locking knob 209 is tightened to fix the drive rod 403. When removing the relay body 100, first loosen the locking knob 209, and then move the drive rod 403 along the first arc groove 207 to drive the disc 401 to rotate. At the same time, the first guide rod 302 is driven to move along the first guide groove 203 through the second arc groove 402 on the disc 401, so that the locking block 301 is put into the second mounting groove 202. Then, the relay body 100 is lifted out of the first mounting groove 201 by the action of the movable plate 501 and the second spring 503.
