[0002] A photovoltaic (PV) power station is a specialized power generation facility that uses solar panels to convert solar energy into electrical energy. Electrical control cabinets are an indispensable and crucial piece of equipment in the construction and operation of a PV power station. These cabinets are primarily used to control, protect, and monitor various electrical devices within the PV power station. To ensure the normal operation of the PV power station, multiple line ports need to be connected to the electrical control cabinet. These line ports serve various purposes, including power transmission, signal control, and data acquisition.

[0003] Typically, electrical control cabinets are equipped with multiple female connectors, which need to connect to the male connectors of the solar panel wiring. The wires from the same group of male connectors are usually housed in a conduit, leaving a section of exposed wire between the conduit and the male connector. To protect the female connectors, male connectors, and exposed wires from direct exposure to the external environment, thus affecting their lifespan, it is essential to design a device for multi-port access in photovoltaic power plants to address these issues.

The semi-ring groove component is fixed on the electrical cabinet and is arranged on the side of the female connector. The rubber sleeve adopts a structure with a larger upper end and a smaller lower end. The rubber sleeve is fitted over the sleeve, and the upper end of the rubber sleeve has an upper connecting ring that can be inserted into the semi-ring groove component. The upper connecting ring also has a fixing ear, which is detachably connected to the electrical cabinet by a locking screw. The lower end of the rubber sleeve has a lower connecting ring, and the lower connecting ring is equipped with a rotary locking head that can be detachably connected to the end of the sleeve.

[0006] The rotary locking head includes a bolt body with a through hole and a nut. The sleeve passes through the through hole. The bolt body and the lower connecting ring are fixedly connected. The nut is threaded onto the bolt body. The bolt body also has several clamping claws that cooperate with the nut, and the clamping claws can abut against the end of the sleeve.

[0007] Both the locking screws and nuts are hand-tightened parts.

[0008] The semi-ring groove component also has mounting ears.

[0009] By adopting the above technical solution, the beneficial effects of this utility model are: This utility model adds a rubber sleeve to the sleeve. The upper part of the rubber sleeve is connected to the electrical cabinet by a combination of snap-fit ​​and screw connection, while the lower part is connected to the sleeve by a rotary locking structure. This design can not only effectively protect the connectors, male-to-female connectors and exposed wire parts, but also make disassembly and assembly convenient. Attached Figure Description

[0011] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0012] like Figure 1-4As shown, this device for multi-port access in photovoltaic power plants includes an electrical cabinet 1, on which are mounted several female connectors 2. The female connectors 2 and male connectors 3 are detachably connected. The wires 3a of the male connectors 3 are sheathed with conduits 6. The female connectors 2 and male connectors 3 adopt existing structures. It also includes rubber sleeves 4 and semi-ringed retaining members 7. In practice, the number of rubber sleeves 4 and semi-ringed retaining members 7 can be increased or decreased according to actual needs. The semi-ringed retaining members 7 are fixed to the electrical cabinet 1 and are arranged on the side of the female connectors 2. Specifically, the semi-ringed retaining members 7 also have mounting ears 7a, which are connected by screws... The nail is connected to the electrical cabinet 1; the rubber sleeve 4 adopts a structure that is larger at the top and smaller at the bottom. The rubber sleeve 4 is fitted over the sleeve 6. The upper end of the rubber sleeve 4 has an upper connecting ring 4a, which can be inserted into the semi-ring groove 7. The upper connecting ring 4a also has a fixing ear 4a1. The fixing ear 4a1 is detachably connected to the electrical cabinet 1 by a locking screw 8. The lower end of the rubber sleeve 4 has a lower connecting ring 4b. Both the upper connecting ring 4a and the lower connecting ring 4b are metal rings. The rubber sleeve 4 is made using existing technology or uses existing products that can be purchased on the market; the lower connecting ring 4b is equipped with a rotary locking head 5 that can be detachably connected to the end of the sleeve 6.

[0013] The rotary locking head 5 includes a bolt body 502 with a through hole and a nut 501. The sleeve 6 passes through the through hole. The bolt body 502 and the lower connecting ring 4b are fixedly connected. The nut 501 is threaded onto the bolt body 502. The bolt body 502 also has several clamping claws 502a that cooperate with the nut 501. The clamping claws 502a can abut against the end of the sleeve 6. With this structure, by tightening the nut 501, the clamping claws 502a are firmly abutted against the end of the sleeve 6, thereby connecting the sleeve 6 and the rubber sleeve 4 together.
