[0002] With the development of the power system, high requirements are placed on power supply and distribution equipment, which needs to have high adaptability and flexibility to meet the needs of increasingly complex projects. The low-voltage dense bus duct system, with its simple design, fast installation, flexibility, safety and strong adaptability, can well meet the needs of modern projects. In order to achieve the technical effect of conversion from conductor to cable, a plug-in box is often set on the dense bus box. The plug-in box is often used as a device for bus output current. The power comes from the dense bus duct. There are several interfaces on the dense bus duct. The plug-in box can be fixedly plugged into the dense bus duct box through the pins on the plug-in box.

[0003] At present, a plug-in box is often needed during the installation and use of dense bus ducts. When the plug-in box is electrically plugged in, it is necessary to plug the plug-in protrusions of the plug-in box into the plug-in grooves of the bus duct accordingly. Due to the large size of the plug-in box, the plug-in box generally needs to be blindly plugged in by feeling when plugging in, and cannot be quickly positioned and plugged in. At the same time, when fixing the box body after plugging in, bolts are generally used to reinforce and stabilize it on the outside. Since the connecting parts are exposed to the outside, it is easy for unrelated personnel to disassemble it from the outside, so the plug-in box cannot be protected. Therefore, the utility model proposes a quick push-on plug-in box suitable for large currents in dense bus ducts. Utility Model Content
