Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a connector machine for photovoltaic modules. Background Art

[0002] Photovoltaic module connectors are an indispensable component in photovoltaic power generation systems and are key elements for photovoltaic modules to transmit electrical energy normally. Conventional photovoltaic module connectors are installed on the back side of photovoltaic modules to lead out the positive and negative terminals of photovoltaic modules to achieve electrical connection with adjacent photovoltaic modules, thereby connecting them in series to form the entire photovoltaic power generation system.

[0003] When installing PV modules, the positive and negative terminals of the PV module connector must be installed together. When PV modules are installed in areas with severe desertification, dust can enter the PV module connector. Excessive dust can even cause the PV module connector to become non-conductive.

[0035] Example 1

[0036] See Figures 1 to 6The present invention provides a connector for a photovoltaic module, comprising a positive connector 11, a negative connector 12 plugged into the positive connector 11, a positive sealing assembly for sealing the connecting end of the positive connector 11, and a negative sealing assembly for sealing the connecting end of the negative connector 12, wherein the positive sealing assembly is rotatably connected to the positive connector 11.

[0037] In some embodiments, the positive electrode sealing assembly includes a retractable bracket rotatably connected to the positive electrode connector 11 and a sealing plug 21 fixed on the retractable bracket. When the positive electrode connector 11 is separated from the negative electrode connector 12, the sealing plug 21 seals the connecting end of the positive electrode connector 11 by rotating the retractable bracket, thereby preventing sand and dust from entering the interior of the positive electrode connector 11 from the connecting end of the positive electrode connector 11.

[0038] In some embodiments, the retractable bracket includes a fixed cover 20, two connecting brackets 22 connected to either side of the fixed cover 20, a fixed tube 23 fixed to the ends of the two connecting brackets 22, and two rotating rods 24. One end of the rotating rod 24 is slidably disposed within the fixed tube 23, and the other end is rotatably connected to the positive connector 11. A sealing plug 21 is fixed to the end surface of the fixed cover 20 facing the positive connector 11 and protrudes from the end surface. The connecting brackets 22 can be extended or retracted by pushing the fixed tube 23. Therefore, after rotating the retractable bracket, the sealing plug 21 can be inserted into or removed from the connection end of the positive connector 11.

[0039] In some embodiments, the retractable bracket further includes a spring 28 sleeved on the rotating rod 24 , and the spring 28 can automatically reset the fixing tube 23 and the connecting frame 22 .

[0040] Furthermore, one end of the rotating rod 24 fixes the sliding plate, the sliding plate is movably disposed in the fixed tube 23 , and the spring 28 is disposed between the sliding plate and the fixed tube 23 .

[0041] In some embodiments, the photovoltaic module connector further includes a guide mechanism connected to the fixing tube 23 , and the guide mechanism is used to push the fixing tube 23 during the rotation of the retractable bracket to allow the connecting frame 22 to retract.

[0042] In some embodiments, the guide structure includes a fixed plate connected to the fixed tube 23 at one end, a fixed rod 27 vertically fixed to the other end of the fixed plate, and a guide block 26 fixed on the positive connector 11. The guide block 26 is arc-shaped and is in sliding contact with the fixed rod 27.

[0043] When the positive connector 11 and the negative connector 12 are separated, the retractable bracket is pushed to rotate toward the connection end of the positive connector 11. During the rotation of the retractable bracket, the fixed rod 27 contacts the guide block 26 and rotates synchronously with the retractable bracket along the curved surface of the guide block 26. During the rotation of the fixed rod 27 along the curved surface of the guide block 26, the fixed plate connected between the fixed rod 27 and the fixed tube 23 pushes the fixed tube 23 to move, thereby extending the connecting frame 22 so that the sealing plug 21 can be inserted into the connection end of the positive connector 11. After the sealing plug 21 is inserted into the connection end of the positive connector 11, the elastic restoring force of the spring 28 causes the fixed tube 23 and the connecting frame 22 to retract, so that the sealing plug 21 tightly seals the connection end of the positive connector 11.

[0044] In some embodiments, the guide structure has two symmetrically arranged guide blocks 26 so that when the positive electrode sealing assembly is used, it can be rotated counterclockwise to seal the connection end of the positive electrode connector 11, or it can be rotated clockwise to seal the connection end of the positive electrode connector 11.

[0045] Furthermore, a limiting groove is formed between the two guide blocks 26 , and the limiting groove can limit the fixing rod 27 . When the positive electrode sealing assembly seals the connecting end of the positive electrode connector 11 , the fixing rod 27 is located in the limiting groove.

[0046] In some embodiments, the retractable bracket further includes a rotating joint 25 , which is fixed to the end of the rotating rod 24 and rotatably connected to the positive connector 11 .

[0047] In some embodiments, the retractable bracket also includes a first torsion spring, which is configured at the connection between the rotating joint 25 and the positive connector 11. When the negative connector 12 is separated from the positive connector 11, the retractable bracket is pushed to rotate under the action of the second torsion spring so that the sealing plug 21 can automatically close the connection end of the positive connector 11.

[0048] In some embodiments, a second torsion spring 17 is provided at the connection portion between the fixing block 16 and the sealing cover plate 15 . When the positive connector 11 is separated from the negative connector 12 , the sealing cover plate 15 automatically blocks the connection end of the negative connector 12 under the action of the second torsion spring 17 .

[0049] In some embodiments, the photovoltaic module connector further includes a traction mechanism connected to the sealing cover plate 15 , and the sealing cover plate 15 is opened by actuating the traction mechanism.

[0050] In some embodiments, the traction mechanism includes a connecting rod 18 hinged to the sealing cover plate 15, a pull rod 19 hinged to the connecting rod 18, and a limit block 29 fixed to the negative connector 12. The limit block has a through hole, and the pull rod 19 slides through the through hole.

[0051] Preferably, the pull rod 19 is arranged in an L-shape, which makes it easy to pull the pull rod 19 to move when in use, and the position of the pull rod 19 is limited by the limit block 29 at the same time.

[0052] In some embodiments, two hooks 13 are symmetrically provided at one end of the positive connector 11, and two hook slot blocks 14 are correspondingly provided at one end of the negative connector 12. The hooks 13 are inserted into the hook slot blocks 14 to mate the positive connector 11 with the negative connector 12.

[0053] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
