Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of wiring, and specifically relates to a wiring structure of photovoltaic module. BACKGROUND
[0002] The wiring structure of the photovoltaic module is a key component in the photovoltaic power generation system, which is responsible for connecting the power generated by the solar cell with the external circuit, thereby conducting the current generated by the photovoltaic module. In the design of the photovoltaic module, the junction box is an important component, which is usually arranged at the intersection of the cell pieces of the photovoltaic module, and is used to connect the circuit with the external circuit. When the circuit is connected, the internal circuit of the junction box is long, which is easy to cause the circuit to be loose, and even disconnected, which brings safety hazards to the photovoltaic module.
[0003] However, the existing wiring structure of the photovoltaic module has the following problems:
[0004] 1. The photovoltaic module generates heat during operation. If there is no proper heat dissipation measure, the heat will cause the temperature of the photovoltaic module and its connecting line to rise. High temperature will affect the efficiency of the photovoltaic module and reduce its power generation capacity. Continuous high temperature environment will accelerate the aging process of the photovoltaic module and the connecting line, thereby shortening their service life. Excessive temperature may cause material degradation, insulation performance degradation and other problems.
[0005] 2. When there is a problem inside the wiring structure, if there is no observation port, the maintenance personnel need to disassemble more external structures to access the internal components, which not only increases the complexity of the maintenance work, but also may cause unnecessary damage. In some cases, there may be high temperature or other dangerous factors inside the wiring structure. Without an observation port, the maintenance personnel cannot know the internal environment in advance when checking or repairing, thereby increasing the safety risk in the operation process.
[0006] 3. If there is no buffer spring, the photovoltaic module may directly bear the impact when subjected to external force, increasing the risk of damage. Without a buffer spring, the photovoltaic module may generate stress due to temperature changes, wind loads and other factors during installation and use. If these stresses are not properly relieved, they may concentrate on some weak points, causing material fatigue or rupture.
[0007] Therefore, the skilled in the art provides a wiring structure of photovoltaic module to solve the problems raised in the above background. UTILITY MODEL CONTENT

[0017] As a further scheme of the utility model: the buffer spring and support rod are arranged between U type cover plate and wiring board respectively.
[0018] Compared with the prior art, the utility model has the advantages that:
[0019] 1. The fins can increase the heat exchange area, help dissipate heat faster, reduce the operating temperature of the photovoltaic module, and improve the overall power generation efficiency. High temperature can damage the materials of the photovoltaic module and accelerate the aging process. Effective heat dissipation measures can slow down this aging process and prolong the service life of the photovoltaic module.
[0020] 2.

Through the observation port, it can regularly check whether there are abnormal conditions inside the wiring structure, such as overheating, short circuit, etc. Safety hazards, which helps to prevent accidents and improve the overall safety of the system.
[0021] 3. The buffer spring can effectively absorb and disperse the mechanical stress that the photovoltaic module may encounter during installation and use. Through the elastic deformation of the buffer spring, stress concentration in a certain point can be reduced, thereby reducing the risk of photovoltaic module damage. In the connection structure of the photovoltaic module, the buffer spring can provide a certain pre-tightening force to ensure the tight contact between the connecting parts.
