Technical Field

[0001] The utility model relates to the field of photovoltaic junction boxes, in particular to a die-casting photovoltaic junction box shell. Background Art

[0002] The die-cast photovoltaic junction box shell is an important component in the photovoltaic power generation system. It is mainly used to connect the solar panels and loads, convert the electricity generated by the panels into usable DC current and output it to the inverter. At the same time, the junction box also plays a role in protecting the panels, waterproof, dustproof, and corrosion-resistant, etc., to ensure the long-term stable output power of the panels.

The correction mechanism is made of aluminum alloy material, achieving the lightweight design goal while maintaining sufficient structural strength and stability.

[0027] In summary, the utility model mainly has the following beneficial effects:

[0028] 1. The utility model sets a correction mechanism, in which due to the joint action of the spring and the rebound plate, the correction mechanism can automatically correct the offset or bent circuit line to restore it to the correct position and direction, which greatly reduces the need for manual intervention and improves the efficiency of installation and maintenance. The design of the extension rod and the clamp ensures a stable connection between the circuit line and the correction mechanism. Even under harsh environmental conditions, such as strong winds, vibrations, etc., the circuit line can maintain a stable position and direction, thereby ensuring the normal operation of the photovoltaic system. At the same time, the setting of the rubber block not only increases the friction and connection stability, but also plays a certain buffering role, which can reduce the damage that the circuit line may suffer during the correction process and extend its service life;

[0029] 2. The utility model sets a sensing mechanism, and the Hall sensor in the sensing mechanism can monitor the position change of the rebound plate in real time. Since the rebound plate is connected to the spring and the rebound rod, its position change directly reflects the compression degree of the spring and the offset of the circuit line. Therefore, the sensing mechanism can feedback the state of the circuit line in real time, providing data support for the stable operation of the system. Moreover, through the precise measurement of the Hall sensor, the system can accurately determine the offset position and degree of the circuit line, which helps to achieve precise control of the circuit line inside the junction box and ensure that it can maintain a stable connection state under various environmental conditions.

[0050] Then, the circuit line 2 is fixedly connected to the housing 1 using the card block 5 and the card slot 4, and the card block 5 is placed above the circuit line 2 and engaged with the card slot 4. Ultrasonic welding is then used to fix the card block 5 to the housing 1 to ensure that the circuit line 2 will not loosen or fall off;

[0051] When in use, the Hall sensor 802 of the sensing mechanism 8 will monitor the position changes of the rebound plate 703 in real time. If the circuit line 2 is offset or loosened, the rebound plate 703 will be reset under the action of the spring 705, and the circuit line 2 will be corrected back to its original position through the rebound rod 704 and the extension rod 706. When the compression of the spring 705 is too large, the Hall sensor 802 will be triggered to facilitate alarm and check the connection status of the circuit line 2.
