Description

Waterproof construction is strengthened to solar panel terminal box Technical Field The utility model relates to the field of junction boxes, in particular to a reinforced waterproof structure of a solar panel junction box. Background Solar panels are installed on the roof of motor homes, and such designs are becoming more common especially in modern motor homes. The solar panel can provide additional power support for a motor home, reduces the dependence on a traditional power supply, and is suitable for long-distance travel or camping. The solar panel of the motor home is mainly used for charging a vehicle-mounted battery and supplying power requirements of low-power electric appliances such as illumination, refrigerators and charging equipment. The installation mode can be fixed or added in later period, and part of users can also carry the foldable portable solar panel to unfold and use when parking. Common solar panel types include monocrystalline silicon, polycrystalline silicon, and flexible solar panels. A junction box is a device for electrical connection and protection. It generally consists of a closed box containing the terminals for connecting cables, wires or electrical equipment. The main function of the junction box is to provide a safe and reliable electrical connection and to protect the electrical connection points from environmental factors. The back of the caravan solar panel is provided with a junction box. In the prior art, the junction box of the solar panel is fixed and adhered to the back of the solar panel through silicone adhesive, and in actual use, the sealing effect of a part area of the silicone adhesive is found to be reduced when the junction box is used for a long time, and although the junction box can be fixed on the surface of the solar panel, moisture and rainwater cannot be prevented from invading, meanwhile, the sealing effect of the junction point of the existing junction box is poor, and the rainwater falls into the junction box from the junction point easily, so that adverse effects are caused to the junction box. Therefore, it is necessary to provide a reinforced waterproof structure for a solar panel junction box to solve the above technical problems. Disclosure of Invention The utility model provides a solar panel junction box reinforced waterproof structure, which solves the problem that the normal use of the junction box is affected due to poor waterproof effect when the existing solar panel junction box of a part of motor home roofs is used in the related technology. In order to solve the technical problems, the utility model provides a solar panel junction box reinforced waterproof structure, which comprises a junction box seat, a waterproof component and a waterproof component, wherein the top of the junction box seat is provided with the waterproof component; The waterproof assembly is including set up in the apron at terminal box seat top, the bottom of apron is provided with the butt joint limit, the outside of butt joint limit just is located the inboard of terminal box seat is provided with first sealed waterproof circle, the left and right sides at apron top all is provided with the screw. Preferably, the left side of terminal box seat is provided with the wiring mouth, the left side of wiring mouth is provided with the screw thread portion of screwing together, the left side of screw thread portion of screwing together is provided with the butt plate, the inboard of butt plate is provided with waterproof leather sheath. Preferably, a nut is disposed on the left side of the junction box seat and located on the outer side of the threaded engagement portion, and a limiting portion is disposed on the left side of the nut. Preferably, an annular groove is formed in the bottom of the junction box seat, and a second sealing waterproof ring is sleeved on the inner side of the annular groove. Preferably, the inner side of the junction box seat is filled with silicone adhesive. Compared with the related art, the reinforced waterproof structure of the solar panel junction box has the following beneficial effects: Through being provided with two waterproof sealing rings, can strengthen sealedly to the top and the bottom of junction box seat, reduce the possibility that moisture and moisture invaded, through screw cap screw into the screw thread portion of screwing for spacing portion removes to the right side, the in-process that spacing portion removed to the right side, the continuous compression butt board, make the butt board by buckling certain angle, and the outer end butt of butt board is at waterproof leather sheath's left end, and then the left end butt of waterproof leather sheath is on the surface of cable, cooperation silicone adhesive filler and apron set up, the waterproof effect of junction has been improved, and a structure is simple and practical, low in manufacturing cost, the waterproof effect of junction box can be improved greatly.
