Description

Technical Field

[0001] This utility model relates to the field of photovoltaic connector technology, and more specifically, to a conductive retaining ring sealing structure. Background Technology

[0002] A photovoltaic connector is a device used to establish an electrical connection between a solar panel and an inverter. It ensures efficient power transmission and system stability. The conductive retaining ring, also known as a locking ring or anti-loosening ring, is a component set inside the housing of the photovoltaic connector. Its main function is to axially limit the conductive terminals to ensure the stability between the conductive terminals and the housing during insertion and removal.

[0003] A search revealed that Chinese patent CN220272820U discloses a photovoltaic connector terminal. By setting a waterproof ring, it ensures that rainwater cannot seep into the interior through the gap between the terminal housing and the wiring end. At the same time, by setting a waterproof plug, which is installed inside the retaining ring, when the terminal housing is connected to the back cover, the waterproof plug inserted in the retaining ring is tightly clamped by the fastening plate, ensuring that rainwater cannot seep into the interior through the gap between the terminal housing and the back cover, thus avoiding damage to the photovoltaic connector.

[0004] When the above-mentioned retaining ring is used, the retaining ring includes multiple fastening plates that are evenly distributed at equal angles on the outside of the first external thread, and the fastening plates are fixedly installed on the first external thread. When the fastening plates are damaged, the entire retaining ring needs to be inspected and replaced, and the inspection and repair costs are high. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a guide ring sealing structure, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide ring sealing structure, including an external threaded head and an extension ring, wherein one end of the external threaded head is fixedly connected to the extension ring, a fixing seat is fixedly sleeved between the external threaded head and the extension ring, two first upright plates are movably arranged inside the fixing seat, and one side of each of the two first upright plates is fixedly connected to the external threaded head, a fastening assembly is provided on the outside of the extension ring, the fastening assembly includes a connecting sleeve, multiple fastening plates, four second upright plates, two lead screws and four compression sleeves, the connecting sleeve is movably sleeved on the extension ring, the multiple fastening plates and the four second upright plates are fixedly sleeved on the connecting sleeve, one end of each of the two lead screws passes through the four second upright plates, and the four compression sleeves are threadedly connected to the two lead screws respectively.

[0007] Furthermore, the connecting sleeve is internally fixedly connected with multiple locking blocks, and the outer sides of the multiple locking blocks all extend into the extension ring.

[0008] It can be seen that the above technical solution aims to improve the stability between the connecting sleeve and the extension ring.

[0009] Furthermore, a buffer pad is fixedly bonded to one side of the connecting sleeve, and one side of the buffer pad is in contact with the external thread head.

[0010] It can be seen that the above technical solution aims to improve the stability between the external thread head and the connecting sleeve.

[0011] Furthermore, each of the four compression sleeves has a fastening washer movably provided on one side, and the four fastening washers are respectively movably sleeved on the two lead screws.

[0012] As can be seen, in the above technical solution, the two fastening shims can improve the stability between the two extrusion sleeves and the lead screw.

[0013] Furthermore, a second sealing gasket is fixedly bonded to the side of the external thread head away from the extension ring.

[0014] Furthermore, a third sealing gasket is fixedly bonded to the side of the extension ring away from the external thread head.

[0015] Furthermore, a first sealing gasket is fixedly bonded to both sides of the fixing base.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model fixes one end of one lead screw through one first vertical plate and two second vertical plates, and limits and fixes one lead screw by two compression sleeves. Similarly, it limits and fixes the other lead screw, thereby fixing the connecting sleeve, external thread head and extension ring together. There is no need to inspect and replace the entire retaining ring, which effectively reduces maintenance costs.

[0018] 2. This utility model improves the sealing performance of the threaded head by adhering a second sealing gasket to one side of the threaded head and mounting the threaded head on the photovoltaic connector. Similarly, the sealing performance of the extension ring side can be improved by using a third sealing gasket. The two first sealing gaskets can further improve the sealing performance between the threaded head, the extension ring and the photovoltaic connector. The structure is simple and the sealing performance is good. Attached Figure Description
