[0005] The working principle is that when wiring, the end of the wire is inserted into the inside of the terminal. Under the action of the automatic clamping component, the wire is fixedly connected inside the terminal, and no screws are needed to fix it. The wiring process is simple, labor-saving and easy, which reduces the work intensity of the operators. Through the setting of the box body and multiple terminals, the situation of messy wiring is avoided, and it is easy to check and distinguish. Through the setting of the automatic fire extinguishing component, when the terminal inside the box body is abnormally hot, the automatic fire extinguishing component is triggered to realize automatic fire extinguishing and cooling inside the box body to avoid the box body catching fire. The setting of the temperature sensor is used to monitor the temperature of the terminal in real time. The temperature sensor adopts the temperature sensor pt500 series. Once the temperature of the terminal is too high, it transmits a signal to the electronic control component. The electronic control component sends a signal to start the automatic fire extinguishing component to achieve rapid cooling.

[0006] Furthermore, the terminal block includes a rectangular body, the rectangular body is a cavity structure, an observation port is provided in the middle of the upper surface of the rectangular body, a guide plate is fixedly provided inside the cavity of the rectangular body, and an arc groove is provided on the upper surface of the guide plate.

At this time, the spring is compressed, and the pressure plate generates a reaction force on the end of the wire by utilizing the restoring force of the spring, so that the end of the wire is firmly fixed inside the cavity, and the lower side wall of the wire fits tightly with the arc groove, thereby realizing a quick electrical connection between the end of the wire and the guide plate, and then realizing the connection of the ends of two different wires through the guide plate, thereby improving wiring efficiency.

By providing an automatic fire extinguishing assembly, when the terminal block inside the box body is abnormally heated, the automatic fire extinguishing assembly is triggered to achieve automatic fire extinguishing and cooling inside the box body to avoid the box body catching fire. The temperature sensor is provided to monitor the temperature of the terminal block in real time. Once the temperature of the terminal block is too high, a signal is transmitted to the electronic control assembly. The electronic control assembly sends a signal to start the automatic fire extinguishing assembly to achieve rapid cooling.

[0012] When the end of the wire to be connected is inserted into the cavity of the rectangular body, the side wall of the end of the wire squeezes the pressure plate, causing the pressure plate to move close to the inner top wall of the cavity. At this time, the spring is compressed, and the pressure plate generates a reaction force on the end of the wire by utilizing the restoring force of the spring, so that the end of the wire is firmly fixed inside the cavity. The lower side wall of the wire fits tightly with the arc groove to achieve a quick electrical connection between the end of the wire and the guide plate, thereby achieving the connection of the ends of two different wires through the guide plate, thereby improving wiring efficiency.
