[0002] With the further improvement of intelligent and Internet of Things technologies, all devices can be connected through the network to achieve remote control and monitoring. For example, the State Grid ensures that all power systems are connected to the grid. For example, photovoltaic power generation generates direct current, which needs to be converted to alternating current through an inverter. Then, the generated power is classified and controlled to be used for different power-consuming devices and different working voltages. If the State Grid needs to connect photovoltaic power generation to the grid, the first step must be to connect the inverter to the collection terminal in its power grid. The existing conventional protocol is the RS485 protocol. The inverter has its own communication port, and the data stick is connected to the inverter communicator host through the communication port. If the State Grid wants to connect the inverter to the collection or metering equipment used in its own power grid, it must be done through a data cable. Because photovoltaic equipment is basically installed in complex environments such as high sunshine, high altitude and uninhabited areas, it has very strict requirements on its lifespan. The standard lifespan of EU photovoltaic equipment is 25 years. Under such high requirements, if you want to maintain an effective connection within 25 years, the connecting line must have the characteristics of high life, high reliability, high stability and adaptive high temperature and high humidity to meet the requirements.

[0017] like Figure 1-2 As shown, a waterproof harness of a protocol converter includes male and female connectors, and the access port of the waterproof harness is divided into a docking zone 1 and a docking zone 2; the docking zone 2 includes a crystal head 2 4, a cover 5 and a panel 6; the docking zone 1 includes an RJ45 female connector 7, a rubber core 9 and a sealing ring 10; one end of the inner core wire 3 of the waterproof harness is pressed into the crystal head 2 4, and the crystal head 2 4 is fixed in the jack set in the middle of the cover 5, and mounting grooves are provided on both sides of the cover 5, and the panel 6 is fixed in the mounting groove of the cover 5 by screws 21; the inner copper wire at the other end of the core wire 3 is divided into two clusters, one cluster is the core wire copper wire 15 welded with the RJ45 female connector 7, and the other cluster is the electric wire copper wire 16 pressed into the crystal head 1 8; the RJ45 female connector 7 is fixed in the middle jack of the rubber core 9; the inner harness has a fitted molded inner film 11 on the outside, the inner film 11 is designed with an inner film groove, and the outer side of the inner film 11 is also wrapped with an outer film 12, and plastic is filled between the outer film 12 and the inner film 11.
[0018] The copper wire 16 is provided with a layer of wire sheath outside, and the interface between the copper wire 16 and the crystal head 8 is wrapped with a crystal head outer film 13.
[0019] A cover foolproofing column 14 is vertically mounted on the panel 6. The foolproofing column can prevent the panel 6 from being inserted wrongly on both sides during installation. The foolproofing column 14 cooperates with the foolproofing hole of the other end. When the panel is inserted in reverse, the foolproofing column 14 prevents the panel from being inserted wrongly on both sides, thereby achieving the purpose of foolproofing.
[0020] A lid hook 17 is vertically welded on the inner side of the lid 5, and a lid wire clamp 18 for fixing the core wire is also provided; a rubber core slot 20 is provided on the inner side of the rubber core 9. In order to enhance the bonding force between the inner film 11 and the lid 5 and the rubber core 9, the lid 5 of the present application is designed with a hook 17, and the rubber core 9 is designed with a rubber core slot 20. When the inner film 11 is formed, the amount of glue of the inner film 11 will be injected into all empty spaces such as the lid hook 17 and the rubber core slot 20 by the pressure of the injection molding machine for filling. After the filling is completed, the inner film 11 is formed.
[0021] The outer film 12 is provided with a plurality of grooves, and the outer film wire clamp 19 is also provided on the outer film 12. When the wire is swayed by external force, the outer film wire clamp 19 will bear and absorb most of the external force, thereby effectively protecting the wire and preventing it from breaking. The plurality of grooves on the outer film 12 can make the wire harness feel more comfortable and less likely to slip during use.
[0022] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific installation and usage methods.
[0023] During the specific installation, Figure 2 As shown, first insert the unpeeled inner skin of the core wire 3 directly into the crystal head 2 4, and then press the terminal of the crystal head 2 4 downward through the tooling. During the pressing process, the pointed piece on the terminal of the crystal head 2 4 will first pierce the inner skin of the core wire, and then contact the copper wire of the core wire to achieve the purpose of contact. After pressing, pass the wires of the pressed crystal head 2 4 together through the jack of the cover 5. After passing through, the outer skin of the core wire 3 is tightly wrapped by the cover wire clamp 18 without any gap. This setting can prevent the phenomenon of glue running when the inner film 11 is formed. At the same time, the cover wire clamp 18 can also position the core wire 3, so that the material is not easy to loosen during the circulation process.
[0024] After the crystal head 2 4 with the core wire passes through the cover jack, the core wire copper wire 15 at the other end is welded to the welding area of the RJ45 female head 7. After welding, the assembly of the semi-finished product can be completed. In order to achieve the purpose of two-in-one, the crystal head 1 8 is the input end, and the wire and the crystal head 1 8 are connected in the same way as the crystal head 2 4. After the connection, the wire copper wire 16 is also welded to the welding area of the RJ45 female head 7. After welding, the entire product is placed in a plastic mold for inner film 11 molding. The main purpose of molding the inner film 11 is to better protect the welding area. In order to enhance the adhesion between the inner film 11 and the cover 5 and the rubber core 9, a cover hook 17 is designed on the cover 5, and a rubber core slot 20 is designed on the rubber core 9. When the inner film 1 During molding, the amount of glue in the inner film 11 will be injected into all empty places such as the cover hook 17 and the rubber core slot 20 by the pressure of the injection molding machine for filling. After the filling is completed, the molding of the inner film 11 is completed. In order to further improve the protection of the product, the inner film 11 is molded and then placed into the outer film plastic mold for further molding. In order to ensure good adhesion between the inner film 11 and the outer film 12, a number of inner film grooves are also designed on the inner film 11. During the injection molding process of the outer film 12, the amount of glue in the outer film 12 will also be injected into all empty places such as the inner film grooves by the pressure of the injection molding machine for filling. When the inner film grooves are fully filled with glue, they will form a good wrapping with the outer film 12 to protect the wires from breaking easily.
[0025] After the outer film 12 is formed, the sealing ring 10 is inserted into the rubber core sealing ring installation groove. When the sealing ring 10 is inserted into the access end of the rubber core 9, it can ensure that there is no gap around the contact area, thereby achieving the purpose of waterproofing.
[0026] After all the previous processes are completed, the panel 6 is finally installed into the cover installation groove, and then the screws 21 are passed through the panel and fastened in the screw holes of the cover. After fastening, the assembly of the entire product can be completed.
[0027] In summary, with the help of the above technical solution of the utility model, the inverter, the acquisition terminal and the data stick can be effectively connected to achieve communication, and it has the characteristics of waterproof, anti-falling and resistance to high temperature and high humidity.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
