Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and specifically to a connector for power distribution cabinets. Background Technology

[0002] Distribution cabinets are primarily used for centralized control, distribution, and protection of electrical energy, playing a crucial role in power systems. They distribute electrical energy from the power source to various branches according to the needs of different electrical equipment or circuits. Simultaneously, various switching devices within the distribution cabinet, such as circuit breakers and disconnectors, control the on / off states of each circuit, thereby enabling the start, stop, and switching on / off operations of electrical equipment. Furthermore, distribution cabinets also protect electrical equipment, equipped with overload and short-circuit protection devices. When a circuit fault occurs, these protective devices quickly activate and automatically disconnect the circuit to prevent damage to electrical equipment due to excessive current, avoiding fires and other safety accidents, thus protecting equipment and personnel safety.

[0003] The guide rails for installing electrical components inside the distribution cabinet are usually screwed onto the side wall of the cabinet after being measured. If the guide rails are found to be misaligned or not properly installed during the installation process, it is difficult to adjust them because they are fixed with screws. The installation process is also very complicated, requiring drilling and tapping of the distribution cabinet before the screws can be tightened. This often results in poor flexibility and convenience, making later maintenance and replacement very inconvenient. Furthermore, the tightness of the screws may affect the stability of the guide rails, causing poor contact of the electrical components on the rails, overheating of the contact points, and in severe cases, short circuits or electrical fires, endangering personal and property safety.
