[0002] Solid-state relays are contactless switches composed of microelectronic circuits, discrete electronic devices, and power electronic devices. Isolation devices are used to isolate the control end from the load end. The input end of the solid-state relay uses a tiny control signal to directly drive a large current load.

[0003] The prior art includes a utility model with a publication number of CN202373521U. The utility model relates to the field of solid-state relays, specifically a solid-state relay with a protective flap, which includes a solid-state relay body and a flap provided at the input and output terminals of the solid-state relay. When wiring, the solid-state relay with a protective flap of the utility model only needs to gently lift the flap from the center of its edge, and after connecting the wires, push it back to its original position to cover the exposed part of the wiring, thereby achieving safety protection when the product is working normally. However, in actual use, the flap lacks effective restraint and is easily opened automatically by external influences, resulting in the loss of protection of the terminal, causing the problem of poor equipment protection effect.

[0004] In order to solve the problem that the flip cover lacks effective restraint and is easily opened automatically by external influences, resulting in loss of protection of the terminal, the existing technology adopts a regular inspection method to deal with it, but it increases the maintenance burden of the equipment, which in turn leads to poor equipment protection effect.

[0008] Preferably, a torsion spring is sleeved on the surface of the rotating rod, and both ends of the torsion spring are fixedly connected to the mounting block and the connecting plate respectively. By setting the torsion spring, when in use, the torsion spring generates elastic force to assist the baffle in resetting.

[0009] Preferably, there are three wire outlet holes, which are arranged in a linear array. The wire outlet holes correspond to the positions of the terminal posts. By setting the wire outlet holes, the wires can be routed normally, which increases the usability of the device and reduces the difficulty of operating the device.

When it is necessary to install the wires, the baffle is rotated and the card block is inserted into the magnet. The magnet and the iron sheet are magnetically attracted. At this time, the baffle is restrained and difficult to rotate, and the wires can be installed. When the wires are installed, the baffle is pulled, the magnet is separated from the iron sheet, and the torsion spring loses its restraint and generates elastic force to squeeze the baffle to reset and re-protect the terminal. By providing the utility model, it is convenient to protect the terminal, and at the same time, the stability of the equipment is increased, the automatic opening of the baffle is reduced, the protective effect of the equipment is enhanced, and installation and maintenance are convenient.
