Description

Technical Field

[0001] The utility model relates to the field of photovoltaic connectors, in particular to a new type of photovoltaic connector. Background Art

[0002] Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation into electrical energy. The energy of the photovoltaic power generation system comes from inexhaustible solar energy, which is a clean, safe and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology. In the photovoltaic power generation system, connectors are basically used to transmit information or current.

[0003] Most of the existing photovoltaic connectors are plug-in or snap-in, and the plug-in is prone to loosening and falling off when subjected to external force, resulting in the inability to connect the photovoltaic converted electricity to the grid, leading to resource waste; although the snap-in is not easy to loosen and fall off, there are also some problems. For example, the prior art 202020291873.3 discloses a high-reliability photovoltaic connector, the prior art 202223011207.8 discloses a photovoltaic panel with a photovoltaic connector fixing structure, and the prior art 202320842220.3 discloses a connector for a photovoltaic power station. All of them use a spring to insert the card block into the card slot to achieve snap-in connection, but the pressing parts that control the card block to detach from the card slot are all located on the surface of the connector, which are easily damaged by collision under the action of external force.

[0008] Preferably, the pressing assembly includes two pressing rods passing through the ends of the female plug and extending into the cavity, connecting blocks respectively arranged at the inner ends of the pressing rods, connecting rods hinged to the connecting blocks and the clamping blocks at both ends, and elastic parts sleeved on the connecting rods; when the pressing rod is pressed to overcome the elastic force of the elastic part, the connecting block will cause the clamping block to move into the cavity and disengage from the clamping slot through the connecting rod; when the pressing rod is released, under the elastic force of the elastic part, the connecting block will cause the clamping block to extend out of the female plug through the connecting rod.

[0009] Preferably, a limit guide is slidably provided in the cavity of the female plug; the inner end of the clamping block is connected to the limit guide; and the connecting rod is hinged to the limit guide.

[0010] Preferably, the two pressure rods are placed in parallel; and a pressing piece connected to the two pressure rods is provided at the outer end of the female plug.

[0029] During installation: press the pressing piece 56 to make the two pressing rods 51 move toward the cavity of the female plug 3 at the same time, drive the connecting block 52 to overcome the elastic force of the tension spring 54 and move the clamping block 4 into the cavity through the connecting rod 53 until the clamping block 4 does not protrude from the surface of the female plug 3; then extend the female plug 3 into the cavity of the male plug 2 until the multiple female plug conductive contacts 32 contact the multiple male plug conductive contacts 22; finally release the pressing piece 56, at this time, under the elastic force of the tension spring 54, the connecting block 52 will make the clamping block 4 just extend into the clamping groove 23 through the connecting rod 53 to achieve clamping.

[0030] When disassembling, the pressing piece 56 is also pressed to make the two pressing rods 51 move toward the cavity of the female plug 3 at the same time, driving the connecting block 52 to overcome the elastic force of the tension spring 54 and move the clamping block 4 into the cavity through the connecting rod 53 until the clamping block 4 is separated from the clamping groove 23; finally, the female plug 3 can be pulled out from the cavity of the male plug 2, which is easy to operate.
