DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] like Figure 1As shown, the present invention provides a double-layer single-sided waterproof terminal block, including a shell 1, an upper wiring assembly 2, and a lower wiring assembly 3. The shell 1 is provided with a first accommodating cavity 11 and a second accommodating cavity 12 which are configured up and down. The upper wiring assembly 2 is arranged in the first accommodating cavity 11, and the lower wiring assembly 3 is arranged in the second accommodating cavity 12. That is, the upper wiring assembly 2 and the lower wiring assembly 3 are designed in a double-layer structure, which not only provides sufficient space to accommodate the wiring assembly, but also enhances the waterproof effect by layering.

[0030] like Figure 2 , Figure 3 As shown, in this embodiment, the double-layer single-sided waterproof terminal block also includes a panel 4 arranged at the front end of the housing 1, and a panel sealing ring 5 is arranged between the panel 4 and the housing 1. In addition, a second mounting groove 13 is arranged on the housing 1, and the panel sealing ring 5 is arranged on the second mounting groove 13, so that the panel sealing ring 5 can fit tightly in the gap between the housing 1 and the panel 4, effectively preventing moisture from penetrating. In addition, the panel sealing ring 5 can be made of a highly elastic and wear-resistant material to ensure its stability and reliability in long-term use. At the same time, the size and shape of the panel sealing ring 5 match the second mounting groove 13, thereby achieving the best waterproof effect.

[0031] like Figure 2 , Figure 4 As shown, in this embodiment, an upper sealing ring 21 is sleeved on the outer side of the upper wiring assembly 2. The upper sealing ring 21 can fit tightly into the gap between the upper wiring assembly 2 and the housing 1, effectively preventing moisture from penetrating between the upper wiring assembly 2 and the housing 1. Even in harsh outdoor conditions, such as continuous rain or high humidity, the upper sealing ring 21 can maintain its excellent sealing performance to ensure the stability and safety of the terminal. In addition, the upper sealing ring 21 can be designed to be made of plastic material. In actual design, the material of the upper sealing ring 21 can be designed according to actual needs. In addition, the upper wiring assembly 2 includes an upper shell 22 and a plurality of upper guide plates 23. The upper sealing ring 21 is sleeved on the outer side of the upper shell 22, that is, the upper sealing ring 21 can fit tightly in the gap between the upper shell 22 and the outer shell 1, thereby forming a complete waterproof barrier; a plurality of upper guide plates 23 are arranged in the upper shell 22, and a second sealant 24 is arranged between the upper guide plates 23 and the inner wall of the first accommodating cavity 11 to enhance the waterproof effect. The second sealant 24 can fill the tiny gap between the upper guide plates 23 and the inner wall of the first accommodating cavity 11 to ensure that moisture cannot penetrate from this part.

[0032] like Figure 2 , Figure 4As shown, in this embodiment, a first mounting groove 221 is arranged around the outer side of the upper shell 22, and the upper sealing ring 21 is arranged in the first mounting groove 221, which not only provides stable positioning for the installation of the upper sealing ring 21, but also enhances the fixing effect of the sealing ring, and through the limiting effect of the first mounting groove 221, the upper sealing ring 21 can be tightly fitted to the outer side of the upper shell 22 to form a solid waterproof barrier. In addition, the provision of the first mounting groove 221 not only simplifies the installation process, but also improves the installation accuracy. The installer only needs to place the upper sealing ring 21 in the mounting groove to easily complete the installation without the need for additional fixing measures. At the same time, the size of the first mounting groove 221 is designed to fit closely with the first sealing ring, so that the first sealing ring will not loosen or shift.

[0033] like Figure 4 , Figure 5 As shown, in this embodiment, the outer side of the upper shell 22 is provided with a snap-in protrusion 222, and the inner side of the shell 1 is provided with a snap-in groove 14. The snap-in protrusion 222 is snap-into the snap-in groove 14. Through close fitting and locking, a firm connection between the upper wiring assembly 2 and the shell 1 is achieved, ensuring a firm connection between the upper wiring assembly 2 and the shell 1, and ensuring that the wiring terminal can remain stable and durable in harsh outdoor environments. In addition, the snap-in design of the snap-in protrusion 222 and the snap-in groove 14 also simplifies the installation process and improves the installation efficiency. The installer only needs to align the snap-in protrusion 222 of the upper shell 22 with the snap-in groove 14 of the shell 1, and then gently press to achieve snap-in, without the need to use additional tools or complicated operations, which not only reduces the installation cost but also improves the work efficiency.

[0034] like Figure 4 , Figure 5As shown, in this embodiment, several rows of upper guide grooves are arranged inside the upper shell 22, and several upper guide vanes 23 are arranged in the corresponding upper guide grooves. The upper guide grooves can separate the several upper guide vanes 23 to prevent the several upper guide vanes 23 from affecting each other. In addition, the upper shell 22 is provided with several first connection holes corresponding to the upper guide vanes 23, and each upper guide vane 23 is provided with a second connection hole. Several first connection members 25 pass through the corresponding first connection holes and the corresponding second connection holes in sequence to fix the upper guide vanes 23 to the upper shell 22, so that a stable mechanical connection is formed between the upper guide vanes 23 and the upper shell 22, which can withstand certain external force impact and vibration, and ensure that the stability of the structure can be maintained even in harsh environments. In addition, this design also facilitates later maintenance and replacement. When the upper guide vane 23 needs to be replaced or repaired, it can be easily completed by disassembling the first connection member 25 without disassembling the entire upper wiring assembly 2, which greatly improves the maintenance efficiency. In addition, the first connecting member 25 can be designed as a bolt. Of course, in actual design, the structure of the first connecting member 25 can be designed according to actual needs.

[0035] like Figure 4 , Figure 5 As shown, in this embodiment, in order to further improve its waterproof performance and structural stability, a first connection plug 26 is provided between the first connection member 25 and the housing 1. The first connection plug 26 can be designed as a bolt plug, and its material selection usually has excellent elasticity and weather resistance to ensure that a good sealing effect can be maintained in various environments. During the installation process, the first connection plug 26 is placed in the gap between the first connection member 25 and the housing 1. Through its elastic deformation, it fits tightly to the contact surface between the two, effectively preventing external substances such as moisture and dust from penetrating from this tiny gap, making the structure of the terminal more compact and stable, and also improving the service life and reliability of the terminal. Even in harsh outdoor environments, the first connection plug 26 can effectively block the intrusion of rain and moisture, ensuring the safety and stability of the electrical connection.

[0036] like Figure 2 , Figure 4 As shown, in the present embodiment, the lower wiring assembly 3 includes a plurality of lower guide plates 31, and a first sealant 32 is provided between the lower guide plates 31 and the inner wall of the second accommodating cavity 12. The first sealant 32 can tightly fill the tiny gap between the lower guide plates 31 and the inner wall of the second accommodating cavity 12, which not only enhances the waterproof performance of the lower wiring assembly 3, but also improves the stability of the entire structure. Even in harsh outdoor environments, such as heavy rain or high humidity environments, the first sealant 32 can effectively block the intrusion of moisture, thereby ensuring the reliability and safety of power transmission.

[0037] like Figure 2 , Figure 4 As shown, in this embodiment, the second accommodating cavity 12 is provided with several rows of lower-layer guide grooves, and several lower-layer guide vanes 31 are arranged in the corresponding lower-layer guide grooves. The lower-layer guide grooves can separate several lower-layer guide vanes 31 to prevent several lower-layer guide vanes 31 from affecting each other. In addition, the bottom of the housing 1 is provided with a third connection hole corresponding to the lower-layer guide vanes 31, and each upper-layer guide vane 23 is provided with a fourth connection hole. The second connection member 33 passes through the third connection hole and the fourth connection hole in sequence to fix the lower-layer guide vane 31 to the housing 1, so that a stable mechanical connection is formed between the lower-layer guide vane 31 and the housing 1, which can withstand certain external force impact and vibration, and ensure that the stability of the structure can be maintained even in harsh environments. In addition, this design also facilitates later maintenance and replacement. When the lower-layer guide vane 31 needs to be replaced or repaired, it can be easily completed by disassembling the second connection member 33 without disassembling the entire lower-layer wiring assembly 3, which greatly improves the maintenance efficiency. In addition, the second connecting member 33 can be designed as a bolt. Of course, in actual design, the structure of the second connecting member 33 can be designed according to actual needs.

[0038] like Figure 2 , Figure 4 As shown, in this embodiment, in order to further improve its waterproof performance and structural stability, a second connection plug 34 is provided at the bottom of the second connection member 33, and the second connection plug 34 is clamped with the housing 1. The second connection plug 34 can be designed as a bolt plug, and its material selection usually has excellent elasticity and weather resistance to ensure that a good sealing effect can be maintained in various environments. During the installation process, the second connection plug 34 is placed at the bottom of the housing 1, and through its elastic deformation, it fits tightly to the contact surface between the two, effectively preventing external substances such as moisture and dust from penetrating from this tiny gap, making the structure of the terminal more compact and stable, while also improving the service life and reliability of the terminal. Even in harsh outdoor environments, the second connection plug 34 can effectively block the intrusion of rain and moisture, ensuring the safety and stability of the electrical connection.

[0039] When assembling the utility model, firstly, the upper guide strip is installed on the upper shell 22, and then the first connecting member 25 is passed upward from the lower side of the upper shell 22 through the first connecting hole of the upper shell 22 and the second connecting hole of the upper guide strip, and then the first connecting plug 26 is covered, and then the second sealing glue 24 is added between the upper guide plate 23 and the inner wall of the first accommodating cavity 11 to achieve the sealing between the upper guide strip and the upper shell 22, and then the upper sealing ring 21 is sleeved on the outer side of the upper shell 22. , then snap the upper shell 22 into the first accommodating chamber 11 of the shell 1; at the same time, install the lower guide plate 31 in the second accommodating chamber 12 of the shell 1, then pass the second connecting member 33 upward from the lower side of the upper shell 22 through the third connecting hole of the shell 1 and the fourth connecting hole of the lower guide plate 31, and then cover the second connecting plug 34, and then add the first sealant 32 between the lower guide plate 31 and the inner wall of the second accommodating chamber 12 to achieve the seal between the lower guide plate 31 and the outer shell. The double-layer structure design of the utility model not only provides enough space to accommodate the wiring assembly, but also enhances the waterproof effect by layering. In addition, the inner wall of the shell 1 compresses the upper sealing ring 21, so that the upper wiring assembly 2, the shell 1 and the lower wiring assembly 3 form a sealed whole, which improves the sealing effect and reduces the airtight defect rate.
