Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic connector. Background Art

[0002] Photovoltaic connectors play a vital role in solar photovoltaic systems. Their main functions include electrical connection, inter-module connection, protection and support of photovoltaic systems. Their main principle is to convert solar light into DC electricity and transmit it to the inverter or grid for storage or use.

[0003] At present, due to installation conditions in some places, photovoltaic connectors need to be installed outdoors. The connection between the positive and negative plastic parts of some existing photovoltaic connectors is fixed by inserting a card block into a limit groove. However, the sealing effect of this connection method is poor. As a result, on rainy days, rainwater may enter the positive and negative plastic parts through the limit groove, which will affect the circuit. In order to solve this technical problem, the utility model proposes a photovoltaic connector. Utility Model Content

[0004] The main purpose of the present invention is to provide a photovoltaic connector that can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A photovoltaic connector includes a positive plastic part, a limiting groove is provided inside the positive plastic part, a fuse is slidably connected to the inside of the positive plastic part, a spring is connected to the inside of the positive plastic part, an end of the spring away from the positive plastic part is connected to a blocking plate, a guide block is connected to the inside of the positive plastic part, a negative plastic part is slidably connected to the inside of the positive plastic part, a sealing ring is sleeved on the outer surface of the positive plastic part, a clamping block is connected to the outer surface of the negative plastic part, a sealing ring is installed on the outer surface of the negative plastic part, and the outer surface of the negative plastic part is connected to the guide block.

[0007] Preferably, the inner side wall of the limiting groove is engaged with the outer surface of the clamping block, and the outer surface of the clamping block is slidably connected to the interior of the positive electrode plastic component.

[0008] Preferably, the outer surface of the fuse is slidably connected to the inside of the negative electrode plastic part, the outer surface of the guide block is slidably connected to the outer surface of the guide block, and the outer surface of the guide block is slidably connected to the inside of the positive electrode plastic part.

[0009] Preferably, the outer surface of the baffle plate is slidably connected to the interior of the positive electrode plastic component, the outer surface of the baffle plate is connected to a transmission block, and the outer surface of the transmission block is slidably connected to the inner side wall of the limiting groove.

[0010] Preferably, the outer surface of the fuse tube is covered with four inner mesh rings, and the outer surfaces of the four inner mesh rings are in contact with the outer surface of the positive electrode plastic component.

[0011] Preferably, the outer surface of the sealing ring 1 is slidably connected to the interior of the positive electrode plastic component, the bottom surface of the clamping block is slidably connected to the upper surface of the blocking plate, and the outer surface of the fuse is connected to a tray.

[0012] Preferably, the outer surface of the tray contacts a transmission plate, the outer surface of the transmission plate is connected to a second spring, and one end of the second spring away from the transmission plate is connected to the interior of the positive electrode plastic component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, through the cooperation between the blocking plate and the guide block and other components, first the blocking plate can be moved. When the card block is inserted into the limit groove, the blocking plate will close the limit groove under the action of the spring, making it difficult for rainwater to enter the positive and negative plastic parts from here, thereby increasing the sealing of the device. The guide block can guide the position of the negative plastic part to move. When the negative plastic part is inserted into the positive plastic part, the guide block on the negative plastic part is blocked by the guide block, so that the negative plastic part is completely inserted into the positive plastic part. Then the card block will be directly inserted into the limit groove, and the user does not need to adjust the position of the negative plastic part later. It is very easy to use and solves the problem that rainwater can easily enter from the limit groove and affect the circuit.

[0015] In the present invention, through the cooperation between the sealing ring 1 and the spring 2 and other components, when the negative electrode plastic part is installed in the positive electrode plastic part, the sealing ring 1 will block between the negative electrode plastic part and the positive electrode plastic part, thereby reducing the possibility of air flowing there, thereby increasing the sealing of the device. The spring 2 can provide thrust for the tray, so that when the user separates the card plate from the limit groove, the thrust provided by the spring 2 to the transmission plate keeps the card block away from the limit groove, preventing them from re-fastening, which is very convenient.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a photovoltaic connector includes a positive electrode plastic part 1, a limiting groove 2 is provided inside the positive electrode plastic part 1, a fuse 3 is slidably connected to the inside of the positive electrode plastic part 1, the inner wall of the limiting groove 2 is relatively smooth, and other objects are subject to less friction when moving on the inner wall of the limiting groove 2. The fuse 3 can be inserted into the positive electrode plastic part 1, and the positive electrode plastic part 1 will limit the position of the fuse 3.

[0024] A spring 14 is connected to the interior of the positive plastic part 1. A blocking plate 5 is connected to the end of the spring 14 away from the positive plastic part 1. The positive plastic part 1 limits the position of the spring 14 and provides thrust for the blocking plate 5 through the spring 14, allowing the blocking plate 5 to move without obstruction.

[0025] The interior of the positive plastic part 1 is connected to a guide block 6, and the interior of the positive plastic part 1 is slidably connected to a negative plastic part 7. The positive plastic part 1 fixes the position of the guide block 6 so that the guide block 6 cannot be easily moved. The negative plastic part 7 can be inserted into the positive plastic part 1, and the positive plastic part 1 limits the position where the negative plastic part 7 can be inserted.

[0026] The outer surface of the positive plastic part 1 is covered with a sealing ring 8, and the outer surface of the negative plastic part 7 is connected to a clamping block 9. The positive plastic part 1 limits the position of the sealing ring 8, and the negative plastic part 7 fixes the position of the clamping block 9, and moves with the clamping block 9 when the negative plastic part 7 moves.

[0027] A sealing ring 2 10 is installed on the outer surface of the negative electrode plastic part 7, and a guide block 11 is connected to the outer surface of the negative electrode plastic part 7. The negative electrode plastic part 7 will limit the position of the sealing ring 2 10, and when the negative electrode plastic part 7 moves, the sealing ring 2 10 will move with it. The negative electrode plastic part 7 will fix the position of the guide block 11, and when the negative electrode plastic part 7 moves, the guide block 11 will move with it.

[0028] The inner side wall of the limiting groove 2 is engaged with the outer surface of the block 9, and the outer surface of the block 9 is slidably connected to the inside of the positive plastic part 1. After the negative plastic part 7 is inserted into the position where it cannot move further in the positive plastic part 1, the block 9 will be stuck in the limiting groove 2. In this way, after the negative plastic part 7 moves to the position where it cannot move in the positive plastic part 1, it cannot be directly withdrawn. The positive plastic part 1 will limit the direction in which the block 9 can move, so that the position of the block 9 will not deviate.

[0029] The outer surface of the fuse 3 is slidably connected to the inside of the negative plastic part 7, the outer surface of the guide block 6 is slidably connected to the outer surface of the guide block 11, and the outer surface of the guide block 11 is slidably connected to the inside of the positive plastic part 1. The negative plastic part 7 will clamp the fuse 3. When the positive plastic part 1 and the negative plastic part 7 are connected together, the positive plastic part 1 and the negative plastic part 7 will limit the position of the fuse 3. The guide block 6 is used to guide the direction in which the guide block 11 can move. In this way, after the negative plastic part 7 is inserted into the positive plastic part 1, the clamping block 9 will be directly clamped into the limiting groove 2, and the guide block 11 will limit the direction in which the positive plastic part 1 can move.

[0030] The outer surface of the blocking plate 5 is slidably connected to the inside of the positive plastic part 1. The outer surface of the blocking plate 5 is connected to the transmission block 12. The outer surface of the transmission block 12 is slidably connected to the inner side wall of the limiting groove 2. The positive plastic part 1 will limit the direction in which the blocking plate 5 can move. The positive plastic part 1 and the blocking plate 5 are sealed. When the blocking plate 5 moves to a position in the positive plastic part 1 where it cannot move under the action of the spring 1 4, the treated blocking plate 5 will block the limiting groove 2, preventing the liquid from passing through the blocking plate 5 and entering the positive plastic part 1.

[0031] The outer surface of the fuse tube 3 is covered with four inner mesh rings 13 , and the outer surfaces of the four inner mesh rings 13 are in contact with the outer surface of the positive electrode plastic component 1 . The four inner mesh rings 13 can be covered on the fuse tube 3 .

[0032] The outer surface of the sealing ring 8 is slidably connected to the inside of the positive electrode plastic part 1, the bottom surface of the block 9 is slidably connected to the upper surface of the blocking plate 5, and the outer surface of the fuse 3 is connected to the tray 14. The sealing ring 8 is used to increase the sealing performance of the device, and the fuse 3 will fix the position of the tray 14.

[0033] The outer surface of the tray 14 contacts the transmission plate 15, and the outer surface of the transmission plate 15 is connected to the spring 2 16. The end of the spring 2 16 away from the transmission plate 15 is connected to the inside of the positive plastic part 1. When the transmission plate 15 moves, it will move with the tray 14. The spring 2 16 will push the transmission plate 15 to move, and the positive plastic part 1 will limit the position of the spring 2 16.

[0034] Working principle: When disassembling it, you first need to pull the transmission block 12 to move the blocking plate 5 out of the limit slot 2, and then the user needs to push the card block 9 out of the limit slot 2. At this time, the spring 2 16 will push the transmission plate 15. The movement of the transmission plate 15 will cause the tray 14 to move with the fuse 3. The movement of the fuse 3 will push the negative plastic part 7 to move. The movement of the negative plastic part 7 will move the card block 9 out of the limit slot 2, so that the user can take these parts off.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
