[0028] Reference Figure 1-5 As shown, the utility model provides a technical solution: a photovoltaic-specific switching power supply substrate, comprising a photovoltaic power supply substrate 1, and four mounting holes 2 are evenly opened on the surface of the photovoltaic power supply substrate 1.

[0029] The following is a detailed description of its overall specific settings and functions.

[0030] In this embodiment: the four corners of the photovoltaic power substrate 1 are all covered with rubber blocks 5, the inner side of the mounting hole 2 is slidably connected with a protective ring 3, and two elastic ropes 9 are fixedly connected between the protective ring 3 and the rubber block 5. The elastic rope 9 is contracted to achieve the stabilization of the rubber block 5 at the corner position of the photovoltaic power substrate 1, thereby achieving the stable installation of the rubber block 5 on the photovoltaic power substrate 1. After the photovoltaic power substrate 1 is disassembled from the photovoltaic power switch, when the photovoltaic power substrate 1 falls from the workbench, the rubber block 5 can achieve the protection of the corner position of the photovoltaic power substrate 1, avoiding the damage of the corner position of the photovoltaic power substrate 1. The side wall of the rubber block 5 is evenly fixedly connected with a plurality of hard bristles 6. The hard bristles 6 have certain elastic properties, and the side of the bent hard bristles 6 is used to contact the ground, which further improves the buffering effect of the rubber block 5 during use.

[0031] The inside of the rubber block 5 is fixedly connected with a spring strip 4, and the upper end of the spring strip 4 is fixedly connected with a connecting column 10, and the upper side of the spring strip 4 is an arc-shaped structure. By setting the spring strip 4, the purpose of buffering and protecting the photovoltaic power source substrate 1 when one side of the components touches the ground can be achieved, and the protection effect of the components on the photovoltaic power source substrate 1 is further improved. The setting of the connecting column 10 avoids the situation where the staff scratches the upper end of the spring strip 4. The inner side of the rubber block 5 is evenly fixedly connected with a plurality of convex strips 7 of different sizes, and the cross-section of the convex strip 7 is triangular. The setting of the convex strip 7 increases the resistance between the rubber block 5 and the photovoltaic power source substrate 1 when the rubber block 5 is pulled.

[0032] Specifically, the side wall of the protection ring 3 is evenly fixedly connected with four stoppers 8. The protection ring 3 is sleeved on the inner side of the mounting hole 2 on the photovoltaic power source substrate 1, and the stoppers 8 will abut against the upper surface of the photovoltaic power source substrate 1.

[0033] The lower end of the protective ring 3 is evenly fixedly connected with four stoppers 8, and the side wall of the stopper 8 is rotatably connected with a rotating piece 12. The rotating piece 12 located on the circular block 11 is rotated out, and the rotating piece 12 is rotated out of the outside of the protective ring 3, so that the installation work of the protective ring 3 inside the mounting hole 2 can be realized. The surface of the rotating piece 12 is glued with an elastic pad 13, and the elastic pad 13 is located between the rotating piece 12 and the photovoltaic power source substrate 1. The elastic pad 13 is filled between the photovoltaic power source substrate 1 and the rotating piece 12, which improves the stability of the rotating piece 12 after it is rotated out.

[0034] Working principle: first rotate the rotating piece 12 on the circular block 11, retract the rotating piece 12 to the inner side of the protective ring 3, and put the protective ring 3 on the inner side of the mounting hole 2 on the photovoltaic power source substrate 1. The stopper 8 will abut against the upper surface of the photovoltaic power source substrate 1. At this time, rotate the rotating piece 12 on the circular block 11, and rotate the rotating piece 12 out of the outer side of the protective ring 3, so that the installation of the protective ring 3 inside the mounting hole 2 can be realized. The elastic pad 13 is filled between the photovoltaic power source substrate 1 and the rotating piece 12, which improves the stability of the rotating piece 12 after it is rotated out. At this time, The rubber block 5 is sleeved on the corner position of the photovoltaic power source substrate 1. The setting of the convex strip 7 increases the resistance between the rubber block 5 and the photovoltaic power source substrate 1 when the rubber block 5 is pulled, and improves the stability of the rubber block 5 installed at the corner position of the photovoltaic power source substrate 1. The elastic rope 9 is contracted to achieve the stabilization of the rubber block 5 at the corner position of the photovoltaic power source substrate 1, thereby achieving the stable installation of the rubber block 5 on the photovoltaic power source substrate 1. After the photovoltaic power source substrate 1 is removed from the photovoltaic power switch, when the photovoltaic power source substrate 1 falls off the workbench The rubber block 5 can realize the protection of the corners of the photovoltaic power source substrate 1, and avoid the damage of the corners of the photovoltaic power source substrate 1. The hard bristles 6 have certain elastic properties. The side of the bent hard bristles 6 contacts the ground, which further improves the buffering effect of the rubber block 5 during use, and further improves the protection effect of the photovoltaic power source substrate 1. By setting the spring strip 4, the purpose of buffering protection when the photovoltaic power source substrate 1 is set on one side of the component touches the ground can be achieved, and the protection effect of the components on the photovoltaic power source substrate 1 is further improved. The setting of the connecting column 10 avoids the situation that the staff scratches the upper end of the spring strip 4. By setting the above structure, the protection performance of the photovoltaic power source substrate 1 when it falls from the workbench is improved, and by setting the protective ring 3, the relative movement between the mounting hole 2 of the photovoltaic power source substrate 1 and the mounting column inside the photovoltaic power switch housing can be realized when the photovoltaic power source substrate 1 is installed, which reduces the wear on the inner side of the mounting hole 2 and further improves the protection effect of the photovoltaic power source substrate 1 during installation and use.
