Description

Technical Field

[0001] The invention relates to the technical field of cable connectors, in particular to a solar photovoltaic panel cable connection mechanism and a solar photovoltaic panel. Background Art

[0002] The cable connection mechanism is an electronic component that connects two cables or a cable and a source device, and is used to achieve functions such as current connection or circuit signal transmission. When the cable connection mechanism is used in a solar photovoltaic panel line, the photovoltaic panel, the inverter and the power module can be connected to realize the conversion of the DC power generated by the photovoltaic panel into a fixed frequency and voltage or frequency and voltage regulated AC power, and store it inside the power module for storage and direct use (for connecting electrical equipment).

[0003] The existing Chinese patent application with publication number CN117394049A discloses a dustproof structure of a photovoltaic connector, including a male component and a female component, the male component including a male shell and a male terminal inserted in the male shell, the female component including a female shell and a female terminal inserted in the female shell, the male terminal including a first connection part and a second connection part connected along the same axis, the female terminal including a third connection part and a fourth connection part connected along the same axis, the first connection part and the third connection part are electrically connected after the male shell and the female shell are plugged in, and the second connection part and the fourth connection part are used to be electrically connected to the photovoltaic cable; the invention can be inserted between the core and the sheath of the photovoltaic cable during the process of feeding the photovoltaic cable to separate the core from the sheath, and the sheath is completely retained after separation, so that there is no need to strip the photovoltaic cable in advance when inserting the photovoltaic cable, reducing the exposed area of ​​the core, and can greatly reduce the contact between the core and dust before and after installation, so that the dustproof effect is significantly improved, and the connection is stable and reliable.

[0004] The existing Chinese patent application with publication number CN117613608A discloses a photovoltaic inverter and connector, including a housing, a circuit board and a connector. The circuit board is arranged in the housing. The connector is fixed to the outer wall of the housing and connected to the circuit board. The connector specifically includes a board-end connector, a cable-end connector and an upper plate conductor. The cable-end connector includes a shell and a magnetic ring. The end of the shell close to the housing is used to accommodate the board-end connector. The end of the shell away from the housing is used to accommodate the magnetic ring; in this invention, the cable is connected to the circuit board through the upper plate conductor, and there is no need to arrange an additional cable between the connector and the circuit board, thereby simplifying the structure of the photovoltaic inverter. In addition, the cable passes through the magnetic ring while passing through the cable-end connector to filter the high-frequency noise of the cable.

[0005] However, the cable connection mechanism has the following defects when used:

[0006] 1. When connecting solar photovoltaic panels, the existing cable connection mechanism generally uses plug-in to connect the male and female parts of the cable to complete the signal or current transmission of the conductive connection. However, in actual operation, the traditional solution is prone to the risk of the connector becoming loose or even falling off due to multiple plug-in and pull-out operations, which can easily cause problems such as leakage. At the same time, when the cable connection mechanism is damaged over a long period of time, it is inconvenient to remove the cable from the inside of the cable connection mechanism, and the maintenance cost is high;

[0007] 2. When inserting the connector into the inverter and realizing the conductive connection operation, the existing cable connection mechanism generally completes the quick connection operation of the two by plugging. However, when the cable connection mechanism plugged into the side of the inverter is actually used, because it is generally suspended, the plug-in inverter and cable connection mechanism are prone to disconnection, and the safety is low.

The external assembly component 20 is arranged on the outside of the plug-in connection structure 30. The external assembly component 20 is fixed on the left and right sides of the inverter 10 by snapping. Among them, the plug-in connection structure 30 includes a port conductive component 40, which is electrically connected to the output end and the input end of the inverter 10, and a conductive male head component 50 is plugged and fixed on the side. The conductive male head component 50 is electrically connected to the port conductive component 40, and the external assembly component 20 is arranged on the outside; and an assembled conductive component 60, which is arranged inside the conductive male head component 50, and a cable component 600 is assembled and fixed on the inside, and the cable component 600 extends to the outside of the conductive male head component 50.

[0072] The above working principle: when the solar photovoltaic panel, the inverter 10 and the power module are connected respectively, the port conductive component 40 is electrically connected to the output and input sides of the inverter 10, and then the conductive male component 50 connected to the cable component 600 is directly installed inside the port conductive component 40 by plugging, so as to complete the conductive connection operation of the cable component 600 and the inverter 10, which is simple and convenient to operate and has high efficiency of plug-in connection. At the same time, for the assembly of the conductive male component 50 and the cable component 600, the assembly and fixation are achieved by assembling the conductive component 60 inside the conductive male component 50, which can ensure the stability of the connection between the cable component 600 and the conductive male component 50 on the one hand, and will not loosen or even fall off when plugged in and out multiple times; on the other hand, when used for a long time, there is enough space for the heat dissipation operation of the conductive connection cable component 600, which is safer. In addition, the design of the structure of the conductive male component 50 can be easily disassembled. When the cable component 600 needs to be maintained or replaced later, the operation is simple and convenient, and the conductive male component 50 needs to be replaced, and the maintenance cost is low.
