[0002] A DC switchboard is an electrical device used in a DC power system to distribute, control, protect, and monitor DC power. It is mainly used in scenarios that require DC power supply, such as solar photovoltaic power plants, communication base stations, data centers, energy storage systems, and rail transportation, and is a key component of DC power supply systems.

[0003] Currently, in the relay protection of DC distribution cabinets, there are protection pressure plates, also known as protection connecting plates. These plates are the bridge and link between the protection device and the external wiring, and are related to whether the protection function and action output can play their normal role.

[0004] The prior art patent application with publication number CN222547175U uses the elastic force of a spring to automatically pull the end of the brake lever close to the contact gear. When the end of the brake lever is embedded in the tooth groove of the gear, it restricts the rotation of the insulating connecting sleeve and the connecting piece, which can effectively prevent the connecting piece from being accidentally touched and moved. In particular, it can prevent electricians from accidentally connecting the circuit when repairing the circuit after disconnecting the connecting piece, thus effectively protecting the safety of electricians. However, one end of the current limiting mechanism is connected to the pressure plate structure through the connecting piece, and this method is prone to the problem that the pressure plate side cannot be limited.

[0005] Therefore, it is necessary to provide a pressure plate structure for relay protection in DC distribution cabinets to solve the above-mentioned technical problems. Utility Model Content

The protective sleeve is sleeved on the surface of the rotating head, the fixing bolt is disposed between the protective sleeve and the rotating head, and the multiple fixing holes are respectively opened between the protective sleeve and the rotating head.

[0011] The connecting components are disposed between the pressure plate bodies;

[0014] Preferably, the connecting assembly includes a connecting plate and two clips, the two clips being respectively connected to both ends of the connecting plate.

[0015] Preferably, the limiting assembly includes a limiting rod, a limiting member, and a limiting bolt. The limiting rod is connected to the surface of the connecting plate, and the limiting member is sleeved on the surface of the limiting rod and located at the connection of the protective sleeve.
