[0040] The left end and bottom end surface of the third block 233 are both smoothly set, and the left end surface of the third block 233 is inclined inward from left to right. When the third block 233 moves to the left, it presses against the support block 2310, so that the block 233 moves outward, thereby driving the straight plate 231 and the second block 232 to move outward.

[0041] The inner wall of the straight plate 231 is in contact with the limiting rod 235 , and the straight plate 231 and the limiting rod 235 are arranged perpendicular to each other, so that the moving track of the straight plate 231 is limited by the limiting rod 235 .

[0042] The inner wall of the slide groove 237 is fitted with the front and rear side walls of the movable frame 2361 and the cover plate 239, and the spring 1 238 is covered by the movable frame 2361 and the cover plate 239 to prevent the spring 1 238 from being exposed to the air and easily adhering to moisture, causing rust.

[0043] See also Figure 7 The elastic component 236 includes a movable frame 2361, a movable plate 2362, a vertical rod 2363 and a spring 2364. The inner bottom of the movable frame 2361 is provided with a movable plate 2362. The middle of the top of the movable plate 2362 is fixedly connected to the vertical rod 2363.

[0044] The vertical rod 2363 and the straight plate 231 are arranged perpendicular to each other, so that when the straight plate 231 moves outward, the movable plate 2362 is driven to move outward through the vertical rod 2363 .

[0045] The top inner wall of the movable frame 2361 fits with the vertical rod 2363, so that the inside of the movable frame 2361 is closed, preventing the spring 2364 from being exposed and easily rusted.

[0046] The present invention provides a buckle structure for photovoltaic wiring harness through improvement, and its working principle is as follows;

[0047] First, when connecting the wire harness 1 4 and the wire harness 2 5, the wire harness 1 4 and the wire harness 2 5 are respectively passed through the first connector 1 and the second connector 2 and the wire harness fixing assembly 3 outside the first connector 1 and the second connector 2, and then the wire harness 1 4 and the wire harness 2 5 are connected, and the connection is wound with a film to perform preliminary protection on the connection of the wire harness;

[0048] Second, the first connector 1 and the second connector 2 are connected. The housing 11 of the first connector 1 is pushed to the right, and the movable ring 22 of the second connector 2 is pushed to the left. The movable ring 22 drives the straight plate 231, the second block 232, the third block 233, the elastic component 236 and the movable cover plate 239 to move to the left synchronously through the limit rod 235. Since the left end surface of the third block 233 is inclined inward from left to right, the third block 233 presses against the support block 2310 when moving to the left, so that the block 233 moves outward. The block 233 drives the straight plate 231 and the second block 232 to move outward, and the right end of the straight plate 231 slides along the limit rod 235. The straight plate 231 is moved by the vertical rod 2363. The movable plate 2362 is driven to squeeze the spring 2364 to move outward, and the block 232 moves outward, so that the block 232 moves to the left and does not contact the block 1 12. When the block 232 is moved to the left side of the block 12, the push on the movable ring 22 is released, and the elastic potential energy generated by the spring 1 238 drives the elastic component 236 to move right. The elastic component 236 drives the straight plate 231 and the block 232 to move right. At the same time, the elastic potential energy generated by the spring 2364 pushes the movable plate 2362 downward. The movable plate 2362 drives the straight plate 231 downward through the vertical rod 2363, so that the block 232 abuts against the left side of the block 12, and the connection between the first connector 1 and the second connector 2 is completed;

[0049] Third, the spring 1 238 generates elastic potential energy to move the block 232 to the right, tightening the housing 1 11 and the housing 2 21. The housing 1 11 and the housing 2 21 are sealed by the sealing ring 25, tightening the housing 1 11 and the housing 2 21, increasing the connection stability between the housing 1 11 and the housing 2 21, and ensuring the sealing effect, thereby increasing the protection effect of the wiring harness connection;

[0050] Fourthly, after the first connector 1 and the second connector 2 are connected, the first connector 1 and the second connector 2 are fixed and sealed to the wiring harness through the wiring harness fixing assembly 3 .
