After the mounting plate 71 at the bottom of the frame 7 of the photovoltaic module is installed in the second U-shaped groove 831 and the fourth U-shaped groove 8341, the tooth tips of the convex teeth 83211 at the end part of the free end 8321 of the tongue piece 832 can be embedded into the mounting plate 71 at the bottom of the frame 7 of the photovoltaic module, so that the mounting plate 71 is not easy to loose. And a third step of: the fastener 9 is tightened using the fastener 9 passing through the mounting hole 8211 of the right-side tab 821 and through the mounting hole 8211 of the left-side tab 821. In the process of tightening the fastener 9, the movable end of the left lug 821 and the movable end of the right lug 821 move towards the inside of the first U-shaped groove 8, so that the left lug 821 and the right lug 821 are driven to elastically deform and move towards the inside of the first U-shaped groove 8, the left lug 821 and the right lug 821 drive two fixing parts 82 which are oppositely arranged, move towards the inside of the first U-shaped groove 8, the two fixing parts 82 which are oppositely arranged drive the cable bearing part 81, move towards the inside of the first U-shaped groove 8, and the left lug 821, the right lug 821 and the cable bearing part 81 are equivalent to hoops, so that the flexible cable 1 is held tightly. The flexible cable 1 applies a force to the fixing portion 82 toward the bottom of the first U-shaped groove 8 or the cable bearing portion 81, and brings the free end 8321 of the tongue 832 on the frame connecting portion 83 to move toward the cable bearing portion 81, and the end of the free end 8321 is far away from the groove wall of the cable bearing portion 81 than the second U-shaped groove 831 and is closer to the cable bearing portion 81, so that when the free end 8321 of the tongue 832 moves toward the cable bearing portion 81, the tooth tips of the teeth 83211 of the end of the free end 8321 of the tongue 832 further bite into and are embedded into the mounting plate 71 at the bottom of the frame 7 of the photovoltaic module, and further firmly locks the mounting plate 71 at the bottom of the frame 7 of the photovoltaic module, so that the elastic connecting piece is not easy to loose.
Referring to fig. 2 to 6, when the photovoltaic module is disassembled, the fastening piece 9 is unscrewed, the movable ends of the two lugs 821 are restored to the open state under the action of the elastic restoring force, and move towards the outer side of the first U-shaped groove 8, so that the two lugs 821 are driven to be restored to the open state, and the first U-shaped groove 8 is restored to the open state under the action of the elastic restoring force, and in this state, since the size of the opening of the second U-shaped groove 831 and the size of the opening of the fourth U-shaped groove 8341 are both larger than the thickness of the mounting plate 71 at the bottom of the frame 7, the second U-shaped groove 831 and the fourth U-shaped groove 8341 mainly support the mounting plate 71 at the bottom of the frame 7, and a special tool can be used to lift the two tongues 832 simultaneously, so that the protruding teeth 83211 at the end parts of the free ends 8321 of the tongues 832 move towards the direction away from the mounting plate 71 at the bottom of the frame 7 of the photovoltaic module, and the elastic connecting piece is pulled out from the frame 7 of the photovoltaic module.
Note that, referring to fig. 2, 3, and 5, the number of the teeth 83211 on the free end 8321 of the tongue 832 is not limited. The special tools used to lift the tongue 832 may be located between adjacent teeth 83211 or may be located on the side of the tongue 832, etc. In the case of a special tool for lifting the tongue 832, the position of action is set between the adjacent teeth 83211, and the shape between the adjacent teeth 83211 may be determined according to the shape of the special tool, with reference to the easy access to the special tool, which is not particularly limited. For example, in fig. 2, 3, and 5, a special tool for lifting the tongue 832 may be disposed between adjacent teeth 83211, a portion between adjacent teeth 83211 may be arc-shaped, the special tool may be arc-shaped, the two shapes of the special tool are adapted, the special tool may extend between adjacent teeth 83211, and the special tool is not easy to slip during the action process.
