Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Examples
As shown in fig. 1-5, the device for preventing loosening of a joint of an overwater photovoltaic module MC4 disclosed by the invention comprises a photovoltaic panel 1, a male joint 2 and a female joint 3, wherein one end of the male joint 2 and one end of the female joint 3 are respectively connected with a cable 5 through nut sleeves 4, the cable 5 is electrically connected with the photovoltaic panel 1, a first wedge-shaped strip 6 is fixedly connected to the end surface of the male joint 2 far away from the cable 5, a first clamping hole 7 is formed in one end of the female joint 3 far away from the cable 5, the male joint 2 is clamped with the female joint 3 through the first wedge-shaped strip 6, a clamping seat 8 is fixedly connected to the lower end surface of the photovoltaic panel 1, a second wedge-shaped clamping strip 9 is fixedly connected to the side wall of the clamping seat 8 far away from the photovoltaic panel 1, second clamping holes 10 are formed in the side walls of the male joint 2 and the female joint 3, and the clamping seat 8 is respectively connected with the male joint 2 and the female joint 3 through the second wedge-shaped clamping strip 9. After the male connector 2 and the female connector 3 of the MC4 connector are connected, the male connector 2 and the female connector 3 are fixed on the clamping seat 8 on the photovoltaic panel 1, and the male connector 2 and the female connector 3 swing together with the photovoltaic panel 1, so that the situation that the MC4 is loosened due to the fact that the MC4 connector is pulled in the swing process of the photovoltaic panel 1 is avoided.
Two baffles 11 which are arranged in parallel are fixedly connected to the side wall, far away from the photovoltaic panel 1, of the clamping seat 8, the baffles 11 are respectively arranged at two ends of the clamping seat 8 in the length direction, and a U-shaped notch 12 for the cable 5 to pass through is formed in each baffle 11. The baffle 11 can prevent the nut sleeve 4 from loosening, so that the male connector 2, the female connector 3 and the cable 5 are always kept connected.
