[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0022] A junction box with a protection device, as Figure 1 shown, includes a bottom plate 1, a junction box body 2 and a protection box body 3. A connecting plate 4 is provided at the bottom of the junction box body 2. The connecting plate 4, the bottom plate 1 and the protection box body 3 are all fixed by bolts 5 and nuts. A groove 6 for accommodating the junction box body 2 is formed on the protection box body 3. Through the design of the protection box body 3, dust and moisture can be effectively prevented from entering the inside of the junction box, reducing electrical failures caused by environmental factors, thereby effectively improving the service life of the junction box and reducing the maintenance frequency. By providing the groove 6, the structural strength of the protection box is increased, and the protection ability for the junction box body 2 is improved. At the same time, the structural design is simple, and the protection box body 3 is fixed by bolts 5 and nuts, which is convenient for the operator to disassemble and repair later.

[0023] Specifically, the protective box body 3 is formed by hemming, and the edges of the protective box body 3 are all welded. A sealing strip is attached to the bottom of the protective box body 3. Through the above settings, hemming and welding can significantly enhance the structural strength of the protective box body 3, enabling it to better withstand external impacts and pressures. The welded protective box body 3 and the sealing strip at its bottom ensure the tightness of the protective box body 3, effectively preventing dust and moisture from entering, thereby protecting the internal electrical components and extending their service life. Moreover, welding is a durable and stable connection method, which helps to extend the service life of the protective box and reduce the maintenance requirements caused by loose or damaged connection parts. Further, the protective box body 3 is made of galvanized steel sheet, and the surface of the galvanized steel sheet is covered with a layer of zinc. This layer of zinc can effectively prevent the steel sheet from rusting and provide excellent corrosion resistance, especially suitable for humid or corrosive environments. At the same time, due to the protective effect of the galvanized layer, the service life of the protective box body 3 is extended, reducing the replacement frequency and maintenance cost caused by corrosion. Combined with the above-mentioned hemming, the blanking area of the protective box body 3 is smaller, and the waste materials can be used for processing, saving costs.

[0024] The connection block 7 is provided on the junction box body 2, and the guiding groove 8 for accommodating the connection block 7 to be embedded and communicating with the groove 6 is opened on the protective box body 3. By setting the connection block 7 and the guiding groove 8, when the operator assembles the junction box body 2 and the protective box body 3, the design of the guiding groove 8 ensures that the junction box body 2 can be accurately embedded into the protective box body 3, improving the installation accuracy and reliability and simplifying the docking process between the junction box body 2 and the protective box body 3. At the same time, during the installation process, the inner wall of the guiding groove 8 also plays a role in limiting the connection block 7, preventing the protective box body 3 from shaking, so as to facilitate the operator to install the bolts 5 and nuts, improving the installation efficiency.

[0025] A rubber pad 9 is provided between the connecting plate 4 and the bottom plate 1. A plurality of through holes 10 for the bolts 5 to pass through are opened on the bottom plate 1, the connecting plate 4, the protective box body 3 and the rubber pad 9. The elasticity of the rubber pad 9 can fill the tiny gap between the connecting plate 4 and the bottom plate 1, improving the overall structural sealing performance, preventing moisture and dust from invading, and the rubber pad 9 can absorb the energy generated by vibration or impact, reducing noise and protecting the internal components of the junction box from damage. The design of the through holes 10 enables the bolts 5 to pass through conveniently, simplifying the installation and adjustment process of the junction box.

[0026] Furthermore, the protection box body 3 is provided with a first hem 11 and a second hem 12. The length of the first hem 11 is greater than that of the second hem 12. The through holes 10 on the protection box body 3 are respectively arranged on the first hem 11 and the second hem 12. There are two connecting blocks 7, and the two connecting blocks 7 are respectively arranged on two adjacent side walls of the junction box body 2. By setting the hems with different lengths, the structural strength of the protection box body 3 can be increased. Especially when the first hem 11 is longer, it can provide additional support and stability. By setting two connecting blocks 7, the connection between the protection box body 3 and the junction box body 2 can be made more balanced, and this layout helps to improve the stability of the entire junction box and its protection device. Especially when subjected to external impact or vibration, through the above settings, not only the structural stability and installation flexibility of the junction box and its protection device are improved, but also the protection effect and maintenance convenience are enhanced.

[0027] The outer edge of the bottom plate 1 is turned downwards to form a support plate 13. The design of the support plate 13 enables the junction box to adapt to different installation environments. The support plate 13 can disperse and absorb external impact forces, reducing the impact directly acting on the bottom plate 1 and the junction box body 2, thereby protecting the internal electrical components. Moreover, the support plate 13 can serve as an additional support structure to improve the stability and load-bearing capacity of the entire junction box and its protection device.

[0028] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
