A photovoltaic connector

Abstract

This application discloses a photovoltaic connector, belonging to the field of photovoltaic connectors. It includes a housing, with a wire fixedly connected to the outer side of the housing. A circular groove is formed on the inner wall of the housing, and a cavity is formed within the inner wall of the circular groove. A receiving groove is formed on the inner wall of the housing, and one end of a return spring is fixedly connected to the inner wall of the receiving groove. A movable post is fixedly connected to the other end of the return spring. A pin is fixedly installed on the side of the movable post away from the return spring. When the pin is installed onto the inner wall of the circular groove, it can be pressed against the slope, and the movable post can be pushed to move within the inner wall of the receiving groove until the pin is dragged to a designated position. Once the position of the mating hole corresponds to the position of the pin, the force of the return spring pushes the pin to reset and insert it into the inner wall of the mating hole. This is used to position the pin, ensuring the stability of the pin after installation and preventing it from easily disengaging.

The push plate is slidably connected to the inner wall of the cavity.

[0007] By adopting the above technical solution, after the pin is installed on the inner wall of the circular groove, the push plate can be pushed to slide on the inner wall of the cavity until the conductive post is completely inserted into the inner wall of the pin. Then, the push plate and the pin can be moved by means of the elastic force of the push spring, which improves the convenience of removing the pin.

[0008] In a preferred embodiment, the inner wall of the receiving groove is provided with a through hole communicating with the circular groove, the pin is adapted to slide and connect to the inner wall of the through hole, and the side of the pin near the slope is disposed inside the circular groove.

[0009] By adopting the above technical solution, when the pin is installed on the inner wall of the circular groove, it can be squeezed along the slope, thereby completely moving and retracting the pin to the inner wall of the through hole, and pushing the moving column to move on the inner wall of the receiving groove.

[0011] By adopting the above technical solution, the convenience of users pulling the moving rod to move the moving column within the receiving groove can be improved.

[0012] In a preferred embodiment, the top of the outer casing has a groove that communicates with a receiving groove, and the moving rod is slidably connected to the inner wall of the groove.

[0013] By adopting the above technical solution, when the pull plate is pushed, the moving rod can be moved along the inner wall of the slide groove, thereby facilitating the movement of the moving column and the pin.

[0014] In a preferred embodiment, one end of a return spring is fixedly connected to the inner wall of the slide, and a moving rod is fixedly connected to the other end of the return spring. A limit rod is fixedly installed on the outer side of the moving rod, and the limit rod passes through the inner wall of the return spring and is slidably connected to the inner wall of the outer shell.

[0015] By adopting the above technical solution, the upper side of the moving rod can be guided, ensuring that the moving rod can stably push the moving column to move, thus preventing interference with the inner wall of the slide. Furthermore, with the help of the elastic force of the return spring, the moving rod can be quickly reset.

[0016] In a preferred embodiment, the movable column is slidably connected to the inner wall of the receiving groove, and the outer diameter of the movable column is adapted to the inner diameter of the receiving groove.

[0017] By adopting the above technical solution, the stability of the moving column when it moves within the inner wall of the receiving tank can be guaranteed, and the moving column will not easily deviate from its position during movement.

[0018] In a preferred embodiment, the inner wall of the circular groove is adapted to be fitted with a pin, the conductive post is inserted into the inner wall of the pin, the outer wall of the pin is provided with a mating hole, and the end of the pin near the slope is inserted into the inner wall of the mating hole.

[0019] By adopting the above technical solution, the pin can be connected to the conductive post by inserting it into the inner wall of the circular groove. In turn, the pin can be inserted into the inner wall of the pin, which can be used to position the pin and ensure the stability of the pin when it is assembled into the circular groove.

[0020] The beneficial effects of this application are: This photovoltaic connector, when the pin is installed on the inner wall of the circular groove, can compress the pin along the slope and push the moving column to move on the inner wall of the receiving groove until the pin is dragged to the designated position and the position of the mating hole corresponds to the pin. Then, with the help of the force of the return spring, the pin is pushed to reset and insert into the inner wall of the mating hole. This is used to position the pin, ensure the stability of the pin after installation, and ensure that it will not easily come off.

[0021] This photovoltaic connector allows the pin to be moved away from the inner wall of the mating hole by pulling the pull plate, which in turn moves the moving rod and the moving column. This facilitates the disassembly of the pin. Simultaneously, the pin can be quickly pushed to the outside by the pushing force of the push spring, achieving separation. Therefore, it cannot be pulled during disassembly. Attached Figure Description

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] Reference Figure 1-4 A photovoltaic connector includes a housing 1, with a wire 2 fixedly connected to the outer side of the housing 1. A circular groove 3 is formed on the inner wall of the housing 1, and a cavity 4 is formed on the inner wall of the circular groove 3. A receiving groove 9 is formed on the inner wall of the housing 1. One end of a reset spring 11 is fixedly connected to the inner wall of the receiving groove 9. A moving post 12 is fixedly connected to the other end of the reset spring 11. A pin 13 is fixedly installed on the side of the moving post 12 away from the reset spring 11. A ramp 14 is formed on the side of the pin 13 away from the moving post 12. A moving rod 15 is fixedly installed on the top of the moving post 12.

[0026] See Figure 2A conductive post 5 is fixedly connected to the inner wall of the cavity 4, and one end of a push spring 6 is fixedly connected to the inner wall of the cavity 4. The other end of the push spring 6 is fixedly connected to a push plate 7. The push plate 7 is slidably connected to the inner wall of the cavity 4, so that after the pin 8 is installed to the inner wall of the circular groove 3, the push plate 7 can be pushed to slide on the inner wall of the cavity 4 until the conductive post 5 is completely inserted into the inner wall of the pin 8. Then, the push plate 7 and the pin 8 can be moved by means of the elastic force of the push spring 6, which improves the convenience of removing the pin 8.

[0027] See Figure 4 The inner wall of the receiving groove 9 is connected to the circular groove 3 by a through hole 10. The pin 13 is adapted to slide and connect to the inner wall of the through hole 10. The side of the pin 13 near the slope 14 is located inside the circular groove 3, so that when the pin 8 is installed on the inner wall of the circular groove 3, it can be squeezed along the slope 14, thereby allowing the pin 13 to be completely moved and retracted to the inner wall of the through hole 10, and the moving column 12 can be pushed to move within the inner wall of the receiving groove 9.

[0028] See Figure 4 A pull plate 16 is fixedly installed on the top of the moving rod 15, which improves the convenience for the user to pull the moving rod 15 to move the moving column 12 within the inner wall of the receiving groove 9.

[0029] See Figure 4 The top of the outer casing 1 is provided with a sliding groove 19 that communicates with the receiving groove 9. The moving rod 15 is slidably connected to the inner wall of the sliding groove 19, so that when the pull plate 16 is pushed, the moving rod 15 can be moved on the inner wall of the sliding groove 19, thereby facilitating the position movement of the moving column 12 and the pin 13.

[0030] See Figure 4 One end of a return spring 18 is fixedly connected to the inner wall of the slide groove 19, and the other end of the return spring 18 is fixedly connected to a moving rod 15. A limiting rod 17 is fixedly installed on the outer side of the moving rod 15. The limiting rod 17 passes through the inner wall of the return spring 18 and is slidably connected to the inner wall of the outer shell 1, so that it can guide the upper side of the moving rod 15 during movement, ensuring that the moving rod 15 can stably push the moving column 12 to move, and thus will not interfere with the inner wall of the slide groove 19. With the help of the elastic force of the return spring 18, the moving rod 15 can be pushed to quickly return to its original position.

[0031] See Figure 4 The movable column 12 is slidably connected to the inner wall of the receiving groove 9. The outer diameter of the movable column 12 is adapted to the inner diameter of the receiving groove 9, which ensures the stability of the movable column 12 when it moves within the inner wall of the receiving groove 9, and further ensures that the movable column 12 will not easily deviate from its position when it moves.

[0032] See Figure 1 - Figure 4The inner wall of the circular groove 3 is adapted to be inserted with a pin 8. The conductive post 5 is inserted into the inner wall of the pin 8. The outer wall of the pin 8 is provided with a mating hole. The end of the pin 13 near the ramp 14 is inserted into the inner wall of the mating hole, so that the pin 8 can be connected to the conductive post 5 by inserting the pin 8 into the inner wall of the circular groove 3. The pin 13 can be inserted into the inner wall of the pin 8, which can be used to position the pin 8 and ensure the stability of the pin 8 when it is assembled into the inside of the circular groove 3.

[0033] Working principle: First, the pin 8 can be taken and inserted into the inner wall of the circular groove 3 until the pin 8 contacts the push plate 7 and slides into the inner wall of the cavity 4. When the pin 8 is installed into the inner wall of the circular groove 3, it can squeeze the pin 13 along the slope 14, thereby moving the pin 13 completely and retracting it into the inner wall of the through hole 10. It can also push the moving column 12 to move into the inner wall of the receiving groove 9 until the pin 8 is dragged to the designated position. After the position of the docking hole and the pin 13 are aligned, the pin 13 can be pushed back into the inner wall of the docking hole by the force of the return spring 11 to position the pin 8. Pulling the pull plate 16 can move the moving rod 15 and the moving column 12 to move the pin 13 away from the inner wall of the docking hole, thereby making it easy to disassemble the pin 8. At the same time, the push spring 6 can be used to quickly push the pin 8 to the outside to achieve separation.
