[0046] Embodiment 1

[0047] Reference Figures 1-5For the first embodiment of the utility model, a longitudinal and transverse multifunctional lightning protection distribution terminal base is provided, which comprises a fixed plate 1; a PCB plate 2 is arranged on the fixed plate 1; a grounding piece 3 is arranged on the fixed plate 1, and the grounding piece 3 is used for being connected with a grounding line; a distribution terminal 4 is arranged on the PCB plate 2 at one end, and the distribution terminal 4 penetrates through the fixed plate 1; a first socket sheet 5 is connected with the grounding piece 3; a second socket sheet 6 is located on one side of the first socket sheet 5, and the second socket sheet 6 is connected with the distribution terminal 4.

[0048] In the embodiment, the fixed plate 1 is in the shape of a rectangular flat plate and is made of high-strength insulating material. The PCB plate 2 is fastened on the upper surface of the fixed plate 1 by screws. The grounding piece 3 is a metal strip and is fixed on the fixed plate 1 by welding, with one end extending out of the edge of the fixed plate for connecting the grounding line. One end of the distribution terminal 4 is fixed on the PCB plate 2 by welding and penetrates through the reserved hole on the fixed plate 1 vertically. The first socket sheet 5 is a copper sheet and is tightly connected with the grounding piece 3 by screws. The second socket sheet 6 is also a copper sheet and is located on the right side of the first socket sheet 5, being connected with the distribution terminal 4 by welding. When the current generated by lightning is transmitted into the distribution terminal 4 through the line, the current first reaches the PCB plate 2, which preliminarily processes and distributes the current. Part of the current is conducted to the subsequent line through the second socket sheet 6, and the other part of the current is conducted to the grounding piece 3 through the first socket sheet 5, and finally is conducted into the ground through the grounding line, thereby realizing lightning protection and distribution functions. The fixed plate 1 provides a stable mounting basis for various components, ensuring the stability of the entire device in harsh environments and reducing the risk of component loosening caused by vibration or external force. The PCB plate 2 realizes preliminary processing and distribution of lightning current, improving the stability and reliability of current transmission. The grounding piece 3 can quickly conduct lightning current into the ground, effectively protecting the safety of equipment and personnel. The design that the distribution terminal 4 penetrates through the fixed plate 1 makes the line connection more orderly, reducing the faults caused by line disorder. The arrangement of the first socket sheet 5 and the second socket sheet 6 ensures the efficiency and stability of current conduction, reduces the contact resistance and energy loss. The overall structure is compact, occupies small space, and is convenient to install and use in limited space, adapting to different installation environments.

[0049] Further, the PCB plate 2 and the fixed plate 1 have a mounting interval 101 therebetween, and the grounding piece 3 further has a first mounting position 301, which is located in the mounting interval 101, and one end of the first socket sheet 5 is arranged on the first mounting position 301.

[0050] In this embodiment, the fixed plate 1 is a flat plate structure. The PCB board 2 is arranged parallel above the fixed plate 1, forming a mounting interval 101 between them. The grounding piece 3 is long strip-shaped, with a first mounting position 301. The first mounting position 301 is located in the mounting interval 101. One end of the first socket piece 5 is fixed on the first mounting position 301 by clamping or welding. After the lightning current enters the distribution terminal 4 and reaches the PCB board 2, part of the current is conducted to the second socket piece 6 through the circuit of the PCB board 2, and the other part of the current is conducted to the first socket piece 5 through the first mounting position 301 on the grounding piece 3, thereby realizing grounding. The mounting interval 101 between the PCB board 2 and the fixed plate 1 provides a reasonable mounting space for the first mounting position 301 of the grounding piece 3, making the structural layout more compact and saving the overall occupied space of the device. The first mounting position 301 is located in the mounting interval 101, effectively protecting the connection part of the grounding circuit, reducing the possibility of external interference and damage, and improving the reliability of grounding. This unique structural design helps to improve the transmission efficiency of current between different components, reduce energy loss, and improve the performance of lightning distribution. It is convenient for the installation and fixation of the first socket piece 5, making its connection more stable and reducing the risk of failure caused by loose connection. Optimizing the space utilization inside the device makes the entire device more miniaturized and integrated, facilitating installation and maintenance.

[0051] Further, the fixed plate 1 has a mounting hole 102, the two ends of the grounding piece 3 have grounding holes 302, and the device further includes a conductive bolt 7, which passes through the grounding hole 302 and the mounting hole 102 in sequence and is connected with the grounding circuit.

[0052] In this embodiment, the fixed plate 1 is a regular-shaped flat plate with mounting hole positions 102. The grounding piece 3 is a long strip-shaped metal piece with grounding hole positions 302 at both ends. The conductive bolt 7 is made of metal, with an inner diameter smaller than the mounting hole position 102 and a nut diameter larger than the grounding hole position 302. When connecting the grounding piece 3 to the grounding line, the conductive bolt 7 is inserted through the grounding hole position 302 at one end of the grounding piece 3 and the corresponding mounting hole position 102 on the fixed plate 1. Since the inner diameter of the conductive bolt 7 is smaller than the mounting hole position 102 and the nut diameter is larger than the grounding hole position 302, the conductive bolt 7 can stably connect the grounding piece 3 to the fixed plate 1, and then the conductive bolt 7 is tightened and fixed to the grounding line, thereby realizing grounding connection. The installation of the mounting hole position 102 and the grounding hole position 302, combined with the conductive bolt 7 with an inner diameter smaller than the mounting hole position 102 and a nut diameter larger than the grounding hole position 302, makes the connection of the grounding piece 3 and the fixed plate 1 and the connection with the grounding line more stable and reliable, not easy to loosen, ensuring good grounding effect. The conductive bolt 7 provides a low-resistance conductive path that can quickly and effectively guide lightning current into the ground, improving lightning protection performance. This detachable connection method facilitates later maintenance and replacement, and if the grounding piece 3 or the conductive bolt 7 is damaged, it can be replaced individually, reducing maintenance costs. The structure is simple and easy to operate, and no complex tools and techniques are needed during installation and disassembly, improving work efficiency. It enhances the versatility of the entire lightning protection terminal base and is suitable for different specifications and types of grounding line connection requirements.

[0053] Further, the PCB board 2 has a let-go slot 201 through which the first and second socket pieces 5 and 6 pass, and further includes a first positioning plate 8 disposed on the fixed plate 1, the first positioning plate 8 having a positioning hole 801 through which the terminal 4 passes.

[0054] In this embodiment, after the lightning current enters the terminal 4, it passes through the PCB board 2, with a part of the current passing through the second socket piece 6 and another part passing through the first socket piece 5. The terminal 4 is precisely positioned by the positioning hole 801. The let-go slot 201 allows the first and second socket pieces 5 and 6 to be arranged more reasonably, avoiding interference with other elements on the PCB board 2 and improving space utilization. The first positioning plate 8 and the positioning hole 801 thereon provide precise positioning and fixation for the terminal 4, enhancing the stability of the terminal 4 connection and reducing the risk of poor contact due to looseness. The optimized internal wiring layout of the device improves the efficiency and stability of current transmission. It helps to improve the assembly precision and production efficiency of the device, reducing production costs. It facilitates later maintenance and repair, allowing quick positioning and replacement of possibly faulty components.

[0055] Further, the device further comprises a connecting pad 9, one end of the connecting pad 9 is arranged on the branch terminal 4, the second socket sheet 6 is arranged on the connecting pad 9, and the first socket sheet 5 and the second socket sheet 6 are respectively located on two sides of the PCB board 2.

[0056] In this embodiment, one end of the connecting pad 9 is tightly mounted on the branch terminal 4. The second socket sheet 6 is fixed on the connecting pad 9 by welding or clamping. The first socket sheet 5 and the second socket sheet 6 are respectively located on two sides of the PCB board 2. When the lightning current enters the branch terminal 4, the current is conducted to the second socket sheet 6 through the connecting pad 9, and the first socket sheet 5 receives the current from the grounding member 3. The arrangement of the connecting pad 9 increases the contact area between the second socket sheet 6 and the branch terminal 4, improves the stability and efficiency of current conduction. The first socket sheet 5 and the second socket sheet 6 are respectively located on two sides of the PCB board 2, which makes the distribution of current more reasonable and reduces mutual interference. The adaptability of the device to different current directions and sizes is enhanced, and the effect of lightning protection branching is improved. It is convenient to install and replace the second socket sheet 6, which reduces the maintenance cost.

[0057] Further, the device further comprises a first mounting shell 10, the first mounting shell 10 is arranged on the fixed plate 1, the first mounting shell 10 has a first inner cavity 1001, the PCB board 2, the grounding member 3, the first socket sheet 5, the second socket sheet 6 and the connecting pad 9 are all located in the first inner cavity 1001, and one end of the first socket sheet 5 and the second socket sheet 6 extends out of the first inner cavity 1001.

[0058] In this embodiment, the lightning current enters through the branch terminal 4 and is shunted and grounded under the action of the internal components, and the processed current is outputted outward through the first socket sheet 5 and the second socket sheet 6 extending out of the first inner cavity 1001. The first mounting shell 10 provides protection for the internal components, reduces the influence of external environmental factors such as dust and moisture on the performance of the components, improves the stability and reliability of the device. The layout of the internal components is more regular, the mutual interference between the components is reduced, and the current transmission path is optimized. The first inner cavity 1001 provides a relatively closed space for the components, which helps to reduce electromagnetic interference and improve signal transmission quality. It is convenient to maintain and replace the internal components as a whole, which improves the maintenance efficiency. The safety of the device is enhanced, and the risk of electric shock caused by accidental touch of internal components by operators is reduced.

[0059] Further, the first socket sheet 5, the second socket sheet 6, the connecting pad 9 and the branch terminal 4 are all several, and the number is the same.

[0060] In this embodiment, the lightning current enters through the multiple branching terminals 4 and is then conducted to the corresponding second socket pieces 6 through the multiple connecting pads 9, while the multiple first socket pieces 5 are subjected to corresponding grounding processing. The multiple components work cooperatively to achieve simultaneous processing and distribution of multiple current paths. The configuration of multiple components of the same number enables simultaneous processing of multiple lightning current paths, improves the branching and lightning protection efficiency of the device, and meets the protection needs of multiple lines. The current distribution is more uniform, reducing the risk of local overheating and overload and prolonging the service life of the device. The versatility and flexibility of the device are improved, and it can adapt to lightning protection branching scenarios of different scales and complexity.
