Description

Technical Field

[0001] The utility model mainly relates to the technical field of photovoltaic power generation equipment, and in particular to a waterproof sealing protection structure for a photovoltaic connector. Background Art

[0002] Photovoltaics, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy. It is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. Photovoltaic power generation systems are divided into independent photovoltaic systems and grid-connected photovoltaic systems. Photovoltaic power generation systems are composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, photovoltaic connectors, AC distribution cabinets, solar tracking control systems and other equipment.

[0003] Photovoltaic power generation systems need to be set up outdoors to receive solar radiation. However, due to weather changes, when it rains or snows, the components of the photovoltaic system will be eroded by rain and snow. The most important of these is the photovoltaic connector. Once rain enters the connector, the photovoltaic will be affected by leakage or power outage, resulting in photovoltaic damage or malfunction. On this basis, a waterproof sealing protection structure for photovoltaic connectors is proposed. Utility Model Content

[0018] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] Reference Figure 1 The present embodiment provides a photovoltaic connector waterproof sealing protection structure, including a photovoltaic connector 1, wherein the outer layer of the photovoltaic connector 1 is wrapped with a photovoltaic film 2. By wrapping the photovoltaic film 2 on the outer layer of the photovoltaic connector 1, the photovoltaic film 2 does not solidify all year round, has unique cold flow characteristics, and has self-repairing ability, which can play a good waterproof sealing effect and prevent water vapor from entering the photovoltaic connector, wherein the photovoltaic film 2 wraps the photovoltaic connector 1 and the connecting wire connected to the photovoltaic connector 1.

[0020] In a preferred embodiment, the outer layer of the photovoltaic film 2 is wrapped with a sealing layer 3 , and the sealing layer 3 is provided to further protect the photovoltaic connector 1 .

[0021] Specifically, the sealing layer 3 is preferably an insulating self-adhesive tape, and another layer of insulating self-adhesive tape is wrapped around the outer layer of the photovoltaic film 2. The insulating self-adhesive tape can provide radial wrapping force for the special photovoltaic film with cold flow characteristics, and secondly, it has good weather resistance itself, and can provide long-term and effective protection for the inner layer of the photovoltaic film 2 and the photovoltaic sealant in various extreme climatic environments.

[0022] A further improvement is that the photovoltaic film 2 and the connection line of the photovoltaic connector 1 are sealed to ensure that there is no gap between the photovoltaic film 2 and the connection line of the photovoltaic connector 1, which plays a good protective role for the photovoltaic connector 1.

[0023] The specific installation steps of the photovoltaic connector waterproof sealing protection structure provided by the utility model are as follows:

[0024] 1. Use a rag or a hair dryer to clean the dirt on the surface of the photovoltaic connector 1. Use solvent to wipe and remove oily dirt;

[0025] 2. Use photovoltaic film 2 (long end) to wrap around the axial direction of photovoltaic connector 1. Note that the length of photovoltaic film at both ends of photovoltaic connector 1 should be consistent;

[0026] 3. Pinch the photovoltaic film 2 that protrudes from both ends of the photovoltaic connector 1 to ensure that there is no gap between the photovoltaic film 1 and the photovoltaic wire;

[0027] 4. Use insulating self-adhesive tape to wrap around the photovoltaic film 2 from one end to the other. The insulating self-adhesive tape should be wrapped according to the 50% to 55% overlap requirement. The overlap seams should be parallel and not twisted or wrinkled. The edges of the insulating self-adhesive tape at both ends of the wrapping should exceed the edge of the photovoltaic film 2 by ≥10mm, and should be pressed so that it does not curl up. The product installation is now complete.

[0028] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
