Description

Technical Field

[0001] This utility model relates to the field of photovoltaic connection, specifically a photovoltaic connection harness. Background Technology

[0002] Photovoltaic wiring harnesses are an indispensable component of solar photovoltaic systems. Their primary function is to conduct the direct current (DC) generated by the solar panels and transmit it to the inverter. The inverter then converts the DC to alternating current (AC) for residential and commercial use. This process involves the connection of multiple components and wiring harnesses, ensuring the efficiency and safety of power conversion. Photovoltaic wiring harnesses typically consist of wires, connectors, and protective sleeves. Their design and manufacturing involve multiple steps to ensure performance and durability. These harnesses can operate stably under various environmental conditions, such as high temperatures, low temperatures, and ultraviolet radiation, thus guaranteeing the long-term stable operation of the solar photovoltaic power generation system.

[0003] However, existing photovoltaic wiring harnesses still have the following problems during use:

[0004] Existing photovoltaic connection harnesses often lack sufficient length during use. A common solution is to plug the male connector of one harness into the female connector of another, which increases the connection length. However, this plugging method is unstable and prone to connection abnormalities due to environmental factors, affecting the normal operation of the equipment. Therefore, it is necessary to develop a photovoltaic connection harness for use in the existing photovoltaic connection field. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the current connection methods between connecting harnesses have poor stability and are prone to connection abnormalities due to environmental influences, which can affect the normal operation of equipment. This utility model proposes a connecting harness for photovoltaic applications.

[0007] Preferably, one end of each slider is fixedly fitted with a mounting plate, and a first adjusting rod is movably fitted on each mounting plate. A fixing plate is fixedly fitted on the bottom surface of each traction port.

[0008] Preferably, each of the fixed plates is movably equipped with a second adjusting rod, one end of which is provided with a rotating groove, and a fixed rod is fixedly mounted on the rotating groove, the fixed rod being movably assembled with the first adjusting rod.

[0009] Preferably, the other end of the connecting line is fixedly fitted with a wire harness male connector, and fixing blocks are fixedly fitted on both symmetrical sides of the wire harness male connector.

[0010] Preferably, each of the fixing blocks has a socket on its surface and an operating cavity inside, which communicates with the socket.

[0011] Preferably, the male and female connectors of the wire harness are plugged in to each other, so that the pins on the assembly block are inserted into the holes of the fixing block.

[0012] The advantages of this utility model are:

[0013] This invention connects the male and female wire harness connectors, allowing the pins on the assembly block to be inserted into the corresponding holes in the fixing block. Turning the knob causes the transmission screw to rotate within the threaded sleeve, moving the sliding block in the traction chamber. The threaded sleeve moves downwards, and the first and second adjusting rods are adjusted via the fixing rod. The angle between the first and second adjusting rods decreases, and they extend out of the operating chamber, increasing the stability between the fixing block and the assembly block and improving connection stability.

[0027] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0028] This application discloses a connecting harness for photovoltaic applications. (Refer to...) Figure 1 and Figure 3 as well as Figure 4 A photovoltaic connecting harness includes a connecting wire 10. One end of the connecting wire 10 is fixedly fitted with a harness female connector 12. Assembly blocks 22 are fixedly fitted on both symmetrical sides of the harness female connector 12. Inserts 23 are fixedly fitted on each assembly block 22. Each insert 23 has an internal cavity 30. Multiple traction ports 31 communicating with the internal cavity 30 are provided on the surface of each insert 23. Each assembly block 22 has a rotating cavity 32. Traction chambers 33 are symmetrically arranged on each rotating cavity 32. Threaded sleeves 41 are movably fitted on each rotating cavity 32, extending into the internal cavity 30. An adjusting block 50 that moves within the internal cavity 30 is fixedly fitted to the top of each threaded sleeve 41. Sliding blocks 42 that move within the traction chambers 33 are symmetrically fixedly fitted to the lower surface of each threaded sleeve 41. A transmission screw 43 that is threadedly fitted to the threaded sleeve 41 is movably fitted on each rotating cavity 32. One end of each transmission screw 43 extends through the mounting block 50. Each of the following components is equipped with a knob 40 fixedly mounted on one end of the transmission screw 43: a slider 51 that moves in the traction port 31 fixedly mounted on the side of the adjusting block 50; a mounting plate 52 fixedly mounted on one end of each slider 51; a first adjusting rod 60 movably mounted on each mounting plate 52; a fixing plate 53 fixedly mounted on the bottom surface of each traction port 31; a second adjusting rod 61 movably mounted on each fixing plate 53; a rotating groove 62 provided at one end of each second adjusting rod 61; a fixing rod 63 fixedly mounted on each rotating groove 62; and the fixing rod 63 movably mounted to the first adjusting rod 60. Twisting the knob 40 causes the transmission screw 43 to rotate in the threaded sleeve 41, allowing the slider 42 to move in the traction cavity 33. The threaded sleeve 41 moves downwards, and the first adjusting rod 60 and the second adjusting rod 61 are adjusted by the fixing rod 63, resulting in a smaller angle between the first adjusting rod 60 and the second adjusting rod 61.

[0029] Reference Figure 1 and Figure 2 The other end of the connecting wire 10 is fixedly equipped with a wire harness male connector 11. Fixing blocks 13 are fixedly equipped on both symmetrical sides of the wire harness male connector 11. The surface of each fixing block 13 is provided with a socket 20. The interior of each fixing block 13 is provided with an operating cavity 21 that communicates with the socket 20. The wire harness male connector 11 and the wire harness female connector 12 are plugged in, so that the pins 23 on the assembly block 22 are inserted into the sockets 20 of the fixing block 13. The knob 40 is turned, so that the first adjusting rod 60 and the second adjusting rod 61 extend out of the operating cavity 21, increasing the stability between the fixing block 13 and the assembly block 22 and improving the connection stability.

[0030] Working principle: The male connector 11 and female connector 12 of the wire harness are plugged in, so that the pins 23 on the assembly block 22 are inserted into the corresponding holes 20 of the fixing block 13. The knob 40 is turned, so that the transmission screw 43 rotates in the threaded sleeve 41, causing the sliding block 42 to move on the traction cavity 33. The threaded sleeve 41 moves downward. The first adjusting rod 60 and the second adjusting rod 61 are adjusted by the fixing rod 63. The angle formed by the first adjusting rod 60 and the second adjusting rod 61 becomes smaller. The first adjusting rod 60 and the second adjusting rod 61 extend out of the operating cavity 21, increasing the stability between the fixing block 13 and the assembly block 22 and improving the connection stability.
