[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with dispersed loads and fewer circuits. The motor control center is used in occasions with concentrated loads and more circuits. The distribution cabinet needs to connect the power cord when working, so the distribution cabinet wiring device is needed. The wiring device is also called the terminal block, which is an accessory product used to achieve electrical connection. It is classified as a connector in the industry.

[0003] The Chinese patent authorization announcement number: CN218586607U provides a wiring device for a distribution cabinet. This patent provides an adjustment mechanism. When the wiring device is connected to the power line inside the distribution cabinet, the wiring terminal is first installed on the moving block, and then the base is placed in a suitable position inside the distribution cabinet. Then, the base is fixed by screwing the fixing piece through the fixing hole, which provides effective guarantee for the installation and fixation of the adjustment block. After the adjustment block is installed and fixed, the pressing columns on both sides of the connecting cylinder can be pressed so that the pressing columns drive the fixed rod under the transmission rod to disengage from the limit groove through the reset spring, so as to facilitate the purpose of loosening the moving block. Then, it is only necessary to push the moving block to slide and adjust to the appropriate position on the internal slide rail of the adjustment block through the transmission frame according to the required requirements, and then loosen the pressing columns on both sides of the connecting cylinder, and then the reset spring resets and drives the fixed rod under the transmission rod to be inserted into the inner side of the limit groove to fix the moving block, thereby providing effective and convenient movement and adjustment of the wiring terminal.
