[0002] The low-voltage grid-connected cabinet is an important device used in photovoltaic power generation systems. It is mainly used to convert the direct current generated by the photovoltaic power generation system into alternating current and connect it to the power grid. It usually includes components such as inverters, power grid detection and protection devices, grounding devices, and corresponding control systems and protection systems. The low-voltage grid-connected cabinet can ensure that the photovoltaic power generation system outputs electrical energy to the power grid safely and stably. It also has functions such as monitoring, protection and fault detection. It is an indispensable part of the photovoltaic power generation system.

[0003] There are many types of power components in the existing low-voltage grid-connected cabinet. The connecting cables of the components need to be wired and inserted through the ports of the low-voltage grid-connected cabinet. The wiring ports of the existing low-voltage grid-connected cabinets are of a certain size. After a small amount of cable wiring is completed, openings or gaps are likely to remain at the ports, which may easily lead to small animals, dust, moisture, etc. directly invading the low-voltage grid-connected cabinet, thereby affecting the wiring use and protection effects of the low-voltage grid-connected cabinet. In addition, the cables directly inserted into the existing ports are bundled and gathered. When a certain cable needs to be inspected and maintained at a later stage, it is inconvenient to pull it out, affecting the convenience of inspection and maintenance, and it is easy for multiple cables to be entangled and damaged when pulled out. Utility Model Content

[0004] In view of the above technical problems existing in the application of the existing low-voltage grid-connected cabinet, the utility model provides a wiring port of the low-voltage grid-connected cabinet.

[0005] A wiring port of a low-voltage grid-connected cabinet comprises a wiring port body arranged at one end of the low-voltage grid-connected cabinet for laying cables, a gasket is arranged in the wiring port body, and a bracket is arranged at one end of the wiring port body, a pad is arranged at one end of the bracket, the pad is passed through the gasket, and a plurality of through holes for wiring are equidistantly distributed at the connection between the pad and the gasket, a baffle is slidably connected in the through hole, the baffle is driven by an elastic component preset in the pad, and movably covers the through hole.

[0006] Furthermore, a plurality of slots are evenly spaced in the pad, and one end of the slot is connected to the through hole.

[0007] Furthermore, the baffle is slidably connected in the card slot, and a buckle slot is provided on the baffle.

[0008] Furthermore, the elastic component includes two springs, the two springs are respectively arranged in the slots, and one end of the spring is fixedly connected to one end of the baffle, and the baffle is elastically driven by the springs and abuts against the through hole.

[0009] Furthermore, a rubber ring is arranged on a circle wall of one side of the pad close to the gasket, the through hole is opened on the rubber ring, one end of the card slot is arranged through the rubber ring, and the gasket is made of sponge.

[0010] Beneficial effects of the utility model:

[0011] 1. Manually move the baffle through the buckle slot to press the spring and press the baffle into the slot, and then pass the cables connecting the components in the low-voltage grid-connected cabinet into the perforations. The baffle cannot be reset through the abutment of the cables, and the baffle is limited. The gasket and rubber ring are used to abut the cables, and the elasticity of the sponge and rubber materials is used to improve the covering effect of the connection between the cable and the perforation. When the cable is pulled out, the abutment against the baffle is released, which drives the spring to unload and rebound, and drives the baffle to abut and cover the perforation, so that the port can complete the cable wiring while avoiding openings or gaps that cause small animals, dust and moisture to directly invade the low-voltage grid-connected cabinet, thereby improving the wiring use effect and protection effect of the low-voltage grid-connected cabinet.

[0012] 2. Through the baffle and gasket, the cables can be laid out one by one in the perforations, making the cables neat and easy to lay or pull out. This makes it easier to inspect and maintain the cables in the low-voltage grid-connected cabinet in the later stage, avoiding the problem of multiple cables being entangled and damaged during maintenance.
