[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0023] The four-in-one photovoltaic connecting line structure schematic view of the utility model is shown in the figure. Figures 1 to 6As shown, the utility model discloses the four converging one type photovoltaic connecting line, including connecting line 1 and insert 2. Connecting line 1 is connected with insert 2 through connecting body 3, realizes that insert 2 is docked one connecting body 3 in four places, to realize that multiple wire bodies converge on one wire body.

[0024] Connecting line 1 is equipped with connecting body 3, and the upper and lower ends of connecting body 3 are equipped with cover plate 4, and the middle of connecting body 3 is equipped with a docking chamber 5, and the docking chamber 5 is equipped with a docking head 6, and the middle of the docking head 6 forms a docking hole 7, and the insert 2 is docked with the docking head 6 in the docking chamber 5.

[0025] The docking chamber 5 is also equipped with a baffle 8, and the baffle 8 and the elastic sheet 9 form a compression area 10. The baffle 8 is equipped with a limiting hole 11 matched with the docking head 6, and the limiting hole 11 is used for matching the insert 2, so that the insert 2 is kept from being separated from the connecting body 3 after being inserted and rotated, and the stable connection between the insert 2 and the connecting body 3 is ensured.

[0026] An elastic sheet 9 is arranged on the connecting body 3, the middle of the elastic sheet 9 is provided with a positioning hole 12 matched with the limiting hole 11, the cross section of the limiting hole 11 is square, the width of the limiting hole 11 and the positioning hole 12 is equal, so that the positioning body 13 can pass through the limiting hole 11 and the positioning hole 12. The elastic sheet 9 is provided with symmetrical retaining bodies 14, when the middle of the elastic sheet 9 is deformed close to the baffle 8, the retaining bodies 14 at this time move towards the positioning hole 12, and when the middle of the elastic sheet 9 is deformed away from the baffle 8, the retaining bodies 14 at this time move away from the positioning hole 12, so that the retaining bodies 14 are opened, and the limiting disc 17 on the insert 2 is placed in the middle of the retaining bodies 14.

[0027] The insert 2 is matched with the connecting body 3, the insert 2 is provided with multiple, and the insert 2 is composed of a main body part 16, a limiting disc 17 and a docking column 18. The docking column 18 passes through the positioning hole 12 and the limiting hole 11 and is placed in the docking hole 7, the elastic sheet 9 is forced to push close to the baffle 8, and the retaining bodies 14 contact and limit the limiting disc 17.

[0028] The limiting disc 17 is provided with a convex lip 19, and the retaining bodies 14 are provided with an extension 20 matched with the lip 19, the extension 20 is matched with the lip 19, and the lip 19 is pushed towards the elastic sheet 9 through the extension 20.

[0029] The docking column 18 is provided with symmetrical positioning bodies 13, and the positioning bodies 13 are provided with inclined surfaces 21 and positioning surfaces 22. A spring 23 is sleeved on the docking column 18, and the outer diameter of the spring 23 is smaller than the maximum outer diameter of the symmetrical positioning bodies 13.

[0031] Because the positioning bodies 13 are symmetrically arranged and there is space between them, the positioning bodies 13 can maintain contact with the baffle 8 after rotation. After rotating 90°, the positioning surface 22 on the positioning body 13 contacts the baffle 8. When it rotates another 90°, the positioning body 13 will no longer contact the baffle 8.

[0032] like Figure 6 As shown, the insert 2 is now installed on the connector 3. The spring 23 applies an external force to push the insert 2 and the elastic plate 9, keeping the elastic plate 9 under force towards the baffle 8, which causes the retainer 14 to pull the limiting plate 17. The other end of the spring 23 applies an external force to the insert 2, keeping the lip 19 on the insert 2 and the extension 20 under force restriction, thereby preventing the insert 2 from easily detaching from the connector 3. Only when rotated 90° can the insert 2 be kept detached from the docking hole 7.
