[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] Reference below Figure 1-Figure 8 A high voltage distribution box according to an embodiment of the present application is described.

[0048] Reference Figures 1 to 3 The high voltage distribution box 100 includes a box body 110 and at least two fuses 130 .

[0049] An input positive wiring part 121 and at least two output positive wiring parts 122 are arranged in the box body 110, and the input positive wiring part 121 and the at least two output positive wiring parts 122 are arranged at intervals along the first direction, so that the space in the box can be fully utilized, so that the size of the entire box will not be too large. The input positive wiring part 121 and the at least two output positive wiring parts 122 maintain a certain distance in space, so that the operator can more easily distinguish them, avoid confusion, and more easily perform wiring operations. The spacing between the input positive wiring part 121 and the at least two output positive wiring parts 122 can reduce electrical hazards caused by misoperation, such as short circuits. The input positive wiring part 121 and the at least two output positive wiring parts 122 maintain a certain distance in space, so that electrical instability caused by physical interference, such as noise interference, can be reduced. The spacing between the input positive power connection portion 121 and the at least two output positive power connection portions 122 can ensure that each connection portion has enough space for connection, making the connection more stable, thereby improving the connection quality of the entire high-voltage distribution box 100.

[0050] The input positive electricity wiring part 121 is used to be electrically connected to the input positive electricity wiring 211, and at least two output positive electricity wiring parts 122 are used to be electrically connected to at least two output positive electricity wirings 212, so that the high-voltage distribution box 100 can transfer positive electricity to at least two output lines. In this way, the high-voltage distribution box 100 can transfer positive electricity to multiple output lines, so that electric energy can be more efficiently distributed and used, avoiding energy waste. By connecting the high-voltage distribution box 100 to multiple output lines, the number and distribution of output lines can be flexibly adjusted according to actual needs to adapt to different application scenarios and needs. Since the high-voltage distribution box 100 can transfer positive electricity to multiple output lines, even if one of the lines fails or is damaged, it will not affect the normal operation of the entire high-voltage distribution box 100, thereby improving the reliability and stability of the high-voltage distribution box 100.

[0051] At least two fuses 130 are arranged in the box body 110, and at least two fuses 130 are arranged corresponding to at least two output positive electrical wiring parts 122; in this way, since the fuse 130 is an overcurrent protection device, when the current exceeds its rated value, the fuse 130 will melt, thereby cutting off the current and protecting the circuit from damage by overcurrent. Therefore, setting the fuse 130 can provide short-circuit protection and ensure the safety of the circuit. If a certain output line fails, the corresponding fuse 130 will melt, thereby disconnecting the faulty line. By replacing the fuse 130, the faulty line can be quickly repaired, which is convenient for maintenance operations. The fuse 130 can isolate the current so that the current of each output line will not interfere with each other or flow in series. In this way, the current of each output line can be ensured to be stable and safe. The fuse 130 can prevent damage to the circuit by overcurrent, reduce the possibility of potential electrical hazards and accidents, and improve the safety of the entire system. By setting multiple fuses 130, the current and load of each output line can be flexibly adjusted according to actual needs to adapt to different application scenarios and needs.

[0052] One end of each fuse 130 is snap-fitted and fixed to the input positive electrical wiring portion 121, and the other end is snap-fitted and fixed to the corresponding output positive electrical wiring portion 122. In this way, the stability of the connection can be ensured and the fuse 130 can be prevented from loosening or falling off during operation. The snap-fitting and fixing method of the fuse 130 can make it more convenient and quick during the installation process, without the need for additional tools or accessories, thereby reducing the difficulty of installation and improving the convenience of maintenance. By directly snapping the fuse 130 to the input positive electrical wiring portion 121 and the output positive electrical wiring portion 122, good contact can be ensured, the contact resistance can be reduced, and the efficiency of current transmission can be improved. The snap-fitting and fixing method can be applicable to fuses 130 of various specifications, so that the high-voltage junction box 100 has good versatility.

[0053] According to the high-voltage junction box 100 of the present application, by providing at least two fuses 130, short-circuit protection can be provided to ensure the safety of the circuit. One end of each fuse 130 is snap-fitted and fixed to the input positive electrical wiring portion 121, and the other end is snap-fitted and fixed to the corresponding output positive electrical wiring portion 122. In this way, the fuse 130 can be installed more conveniently and quickly without the need for additional tools or accessories, thereby reducing the difficulty of installation and improving the convenience of maintenance. By snapping the fuse 130 directly to the input positive electrical wiring portion 121 and the output positive electrical wiring portion 122, good contact can be ensured, contact resistance can be reduced, and the efficiency of current transmission can be improved. The snap-fitting and fixing method can be applied to fuses 130 of various specifications, so that the high-voltage junction box 100 has good versatility.

[0054] Specifically, refer to Figures 2 to 4In the embodiment of the present application, at least two output positive electrical wiring parts 122 include a parallel output positive electrical wiring part 122, and the parallel output positive electrical wiring part 122 has a first wiring part 1221 and a second wiring part 1222, and the first wiring part 1221 and the second wiring part 1222 are electrically connected, and the output positive electrical wiring 212 includes parallel wiring, and the parallel wiring includes a first wiring 2121 and a second wiring 2122, and the first wiring 2121 and the second wiring 2122 are electrically connected to the corresponding first wiring part 1221 and the second wiring part 1222, respectively, so that the first wiring 2121 and the second wiring 2122 are arranged in parallel. In addition, at least two fuses 130 include a first fuse 130, one end of the first fuse 130 is electrically connected to the input positive electrical wiring part 121, and the other end is electrically connected to the parallel output positive electrical wiring part 122. In this way, by arranging the first wiring 2121 and the second wiring 2122 in parallel, the reliability of the circuit can be increased. When one of the wirings fails, the other wiring can continue to transmit current to ensure the normal operation of the circuit. By electrically connecting the first wiring 2121 and the second wiring 2122 to the corresponding wiring parts respectively, the circuit design can be simplified and the simplicity and maintainability of the circuit can be improved. By electrically connecting one end of the first fuse 130 to the input positive wiring part 121 and the other end to the parallel output positive wiring part 122, the current can be effectively divided into two paths, reducing the current intensity in the circuit, reducing the potential overheating and short circuit risks, and improving the safety of the circuit. By setting the first wiring 2121 and the second wiring 2122 in parallel, when one of the wirings fails, the corresponding wiring part can be easily replaced without the need to repair the entire circuit, thereby improving the efficiency of maintenance and replacement. By electrically connecting one end of the first fuse 130 to the input positive wiring part 121 and the other end to the parallel output positive wiring part 122, the current path and intensity in the circuit can be adjusted according to actual needs to adapt to different application scenarios and circuit requirements. The number of fuses 130 can also be reduced to save costs.

[0055] It should be noted that the present application does not limit the specific shape and number of the input positive electrical wiring portion 121 and the at least two output positive electrical wiring portions 122. In another embodiment, the current output through the input positive electrical wiring 211 can be divided into multiple branches and flow through multiple output positive electrical wiring portions 212 after passing through multiple fuses 130. The number of multiple output positive electrical wiring portions 212 here can be the same as the number of multiple fuses 130.

[0056] Reference Figure 2 and Figure 7In one embodiment, the two ends of each fuse 130 are respectively fixed to the input positive wiring part 121 and the corresponding output positive wiring part 122 by a clamp 140, so that the axial dimension of the high-voltage junction box 100 can be made smaller. By using the clamp 140 to fix the two ends of the fuse 130 to the input and output wiring parts, the reliability and stability of the connection can be ensured, and the fuse 130 can be prevented from loosening or falling off during operation. Using the clamp 140 for fixing can simplify the operation process, without the need for additional tools or accessories, and facilitate installation and maintenance.

[0057] By using the clamp 140 for fixing, it can be applied to fuses 130 of different specifications and shapes, so that the high-voltage junction box 100 has good versatility. By fixing the two ends of the fuse 130 to the input positive power connection part 121 and the output positive power connection part 122 respectively, it can be avoided that the fuse 130 is pulled out or replaced by mistake during operation, thereby improving the safety of the high-voltage junction box 100. Since the two ends of the fuse 130 are fixed to the input and output connection parts by the clamp 140 respectively, it can be ensured that the fuse 130 remains stable when affected by factors such as mechanical vibration and temperature changes, reducing potential problems.

[0058] It should be noted that, in one embodiment, the clamp 140 is electrically connected to the fuse 130, and the clamp 140 is electrically connected to the corresponding input positive electrical wiring part 121 or the output positive electrical wiring part 122. In this way, by electrically connecting the clamp 140 to the fuse 130, the circuit design can be simplified, the use of external connections and components can be reduced, and the simplicity and maintainability of the circuit can be improved. By electrically connecting the clamp 140 to the corresponding input positive electrical wiring part 121 or the output positive electrical wiring part 122, the circuit connection, disconnection and maintenance operations can be conveniently performed, and the efficiency of operation and maintenance can be improved. By adjusting the connection method between the clamp 140 and the fuse 130, the current path and intensity in the circuit can be adjusted according to actual needs to adapt to different application scenarios and circuit requirements. The electrical connection between the clamp 140 and the fuse 130 can make the circuit connection more flexible and convenient, thereby improving the interchangeability and adaptability of the circuit connector.

[0059] In addition, in the embodiment of the present application, the material of the clamp 140 includes a conductive material. Thus, the clamp 140 made of the conductive material can be electrically connected to the fuse 130 , and the clamp 140 can also be electrically connected to the corresponding input positive electrical wiring portion 121 or the output positive electrical wiring portion 122 .

[0060] Reference Figure 2 , Figure 5 as well as Figure 7 In one embodiment, the clamp 140 includes a connecting portion 141 and two clamping arms 142 .

[0061] The connection part 141 is connected to the input positive power connection part 121 or the output positive power connection part 122. Thus, by connecting the connection part 141 to the input positive power connection part 121 or the output positive power connection part 122, the number and length of the connection wires can be reduced, thereby reducing resistance and energy loss, and improving the efficiency of the entire circuit. The connection part 141 is directly connected to the input positive power connection part 121 or the output positive power connection part 122, which can increase the stability of the connection and reduce loosening or falling off caused by vibration or other factors.

[0062] The two clamping arms 142 are arranged relative to each other and at intervals, one end of the two clamping arms 142 is connected to the connecting portion 141, and the other ends of the two clamping arms 142 can be close to each other so that the two clamping arms 142 are suitable for clamping the fuse 130 or away from each other so that the two clamping arms 142 are suitable for loosening the fuse 130. In this way, by using the two clamping arms 142, the fuse 130 can be conveniently clamped or loosened, making the operation simpler and faster. Since the two clamping arms 142 can be close to or away from each other, they can be applied to fuses 130 of different specifications and shapes, and have a wider adaptability. By arranging the two clamping arms 142 relative to each other, the stability and accuracy of the operation can be increased, and the fuse 130 can be prevented from being deflected or falling off during the operation. By using the design of the two clamping arms 142, the fuse 130 can be easily replaced or repaired, reducing the difficulty and cost of maintenance.

[0063] Reference Figure 5 and Figure 7 In one embodiment, each clamping arm 142 includes an elastic connecting section 1421 and a clamping section 1422 which are sequentially connected and arranged in a direction away from the connecting portion 141. In this way, the elastic connecting section 1421 can allow the clamping arm 142 to move and bend within a certain range to adapt to fuses 130 of different shapes or sizes, making the installation process simpler and smoother. Due to the elasticity and adaptability of the elastic connecting section 1421, it can better absorb and disperse external forces, thereby providing more stable and reliable support to prevent the clamping arm 142 from moving or deforming in the direction of the connecting portion 141. The connection design of the elastic connecting section 1421 and the clamping section 1422 can provide a more reliable and lasting structural support, making the clamping arm 142 more durable and reliable during the entire use process.

[0064] The free end of the elastic connecting section 1421 is connected to the connecting portion 141, and the clamping section 1422 is formed with a clamping groove a toward the other clamping arm 142. The clamping grooves a of the two clamping arms 142 are jointly arranged to form a clamping space for clamping the fuse 130. In this way, the design of the clamping groove a can make the two clamping arms 142 cooperate with each other to firmly fix the fuse 130 in the clamping space, thereby preventing the fuse 130 from moving or falling off during the installation process. The clamping space formed by the clamping grooves a of the two clamping arms 142 can quickly and accurately install the fuse 130, thereby improving the installation efficiency. The design of the clamping groove a makes it unnecessary to use additional tools or complicated operation steps when installing and removing the fuse 130, thereby facilitating the operation of the operator. The design of the elastic connecting section 1421 allows the clamp 140 to be suitable for fuses 130 of different types and sizes, and allows the elastic connecting section 1421 to undergo different deformations so that the size and shape of the clamping slot a can be adjusted to accommodate different fuses 130 .

[0065] Reference Figure 7 In one embodiment, each clamping arm 142 further includes a guide section 1423, which is connected to the free end of the clamping section 1422, and the distance between the guide sections 1423 of the two clamping arms 142 in the direction away from the connecting portion 141 is set to be incremental, so that the design of the guide section 1423 can guide the clamping arm 142 to move correctly, ensuring that the fuse 130 can smoothly enter the clamping slot a and be correctly installed. The design of the guide section 1423 can play a buffering role, reducing the impact or damage to the clamping arm 142 and the fuse 130 caused by incorrect operation or irregular movement during the installation process. Through the design of the guide section 1423, the stability of the clamping arm 142 can be increased, making the clamping arm 142 more stable in the direction of the connecting portion 141, thereby ensuring the stable installation of the fuse 130. The design of the guide section 1423 can provide clear guidance instructions, so that the operator can install the fuse 130 more conveniently and accurately. The design of the guide section 1423 can be adjusted according to different sizes and shapes of the fuses 130 to meet the requirements of different fuses 130 and improve the adaptability of the clamping arm 142 .

[0066] Reference Figure 7In one embodiment, along the direction away from the connecting portion 141, the elastic connecting arm of one clamping arm 142 is tilted toward the other clamping arm 142. In this way, the tilted design of the elastic connecting arm can increase the stability of the clamping arm 142, making the clamping arm 142 more stable in the direction of the connecting portion 141, thereby ensuring the stable installation of the fuse 130. The tilted design of the elastic connecting arm can better adapt to fuses 130 of different shapes or sizes, making the installation process simpler and smoother. The tilted design of the elastic connecting arm can provide more flexible and convenient operating performance, allowing operators to install the fuse 130 more easily. The tilted design of the elastic connecting arm can increase the structural strength of the clamping arm 142, and improve the durability and service life of the clamping arm 142.

[0067] Reference Figure 3 and Figure 6 In one embodiment, each connection part 141 is fixed to the corresponding input positive wiring part 121 or output positive wiring part 122 by a screw connector 151. In this way, the screw connector 151 can provide reliable fixation, so that the connection part 141 can be stably connected to the input positive wiring part 121 or the output positive wiring part 122, ensuring the stability and reliability of the circuit. The design of the screw connector 151 makes it easy and convenient to install and remove the connection part 141. The operator can remove and install the connection part 141 by simply rotating the screw connector 151. The design of the screw connector 151 can be applicable to connections 141 and input positive wiring parts 121 or output positive wiring parts 122 of different types and sizes, and has a wide range of applicability. The connection part 141 connected by the screw connector 151 can provide good electrical performance, so that the current can flow smoothly through the connection part 141, ensuring the normal operation of the circuit. The design of the screw connector 151 can prevent misoperation and protect the safety and stability of the circuit.

[0068] Reference Figures 5 to 7In one embodiment, a rotation-stopping structure is further provided between the connection portion 141 and the box body 110. The rotation-stopping structure includes a rotation-stopping protrusion 161 extending axially along the screw connection 151 and a rotation-stopping groove 162 matched with the rotation-stopping protrusion 161. One of the rotation-stopping protrusion 161 and the rotation-stopping groove 162 is provided on the connection portion 141, and the other is provided on the box body 110. In this way, the design of the rotation-stopping structure can prevent the connection portion 141 from rotating relative to the corresponding input positive wiring portion 121 or output positive wiring portion 122, thereby ensuring the connection stability between the connection portion 141 and the corresponding input positive wiring portion 121 or output positive wiring portion 122. The design of the rotation-stopping protrusion 161 and the rotation-stopping groove 162 can increase the structural strength between the connection portion 141 and the corresponding input positive wiring portion 121 or output positive wiring portion 122, thereby improving the durability and service life of the high-voltage junction box 100. The design of the anti-rotation structure can simplify the installation process, so that the operator can more conveniently install the connection part 141 and fix it on the corresponding input positive power connection part 121 or output positive power connection part 122. The design of the anti-rotation protrusion 161 and the anti-rotation groove 162 can make the connection between the connection part 141 and the corresponding input positive power connection part 121 or output positive power connection part 122 more flexible and convenient, thereby improving the assembly efficiency.

[0069] Refer to 5 and Figure 7 In one embodiment, each clamp 140 is further provided with a first limiting portion 143, and each first limiting portion 143 is used to abut against the end face of the corresponding fuse 130. In this way, the design of the first limiting portion 143 can accurately position the fuse 130, ensure that the fuse 130 is in the correct position, and avoid installation errors or position deviations. By the first limiting portion 143 abutting against the end face of the fuse 130, the fuse 130 can be effectively limited inside the clamp 140 to prevent the fuse 130 from exploding or being damaged due to overheating.

By providing the first limiting portion 143, the installation process can be simplified, and the operator can more conveniently install the fuse 130 inside the clamp 140, thereby improving the installation efficiency.

[0070] Reference Figure 1 and Figure 8 In one embodiment, the box body 110 includes a box body 111 and a cover body 112 .

[0071] The box body 111 is formed with an opening 1111, and an input positive wiring part 121 and at least two output positive wiring parts 122 are arranged in the box body 111. In this way, the input positive wiring part 121 and the output positive wiring part 122 are arranged in the box body 111, which can be conveniently maintained and operated. The opening 1111 design of the box body 111 is convenient for operators to connect, replace or repair the circuits inside the box body 111. The input positive wiring part 121 and the output positive wiring part 122 are arranged in the box body 111, which can effectively prevent the occurrence of safety problems such as accidental contact and short circuit. The box body 111 can play a protective role, reduce the interference and influence of the external environment on the internal wiring part, so that the high-voltage distribution box 100 can adapt to different environments and conditions.

[0072] It should be noted that the present application does not limit the shape and size of the box body 110. The size and shape of the box body 111 can be adjusted as needed to meet the needs of different circuits. At the same time, the input positive power connection part 121 and the output positive power connection part 122 can be configured and adjusted according to actual needs.

[0073] The cover 112 sealing cover is arranged at the opening 1111 and is detachably connected to the box body 111. In this way, the setting of the cover 112 can protect the circuit components inside the box body 111 and prevent dust, moisture or other pollutants from entering the box, thereby maintaining the stability and reliability of the circuit. By detachably connecting the cover 112 to the box body 111, the operator can easily open the cover 112 to access the internal circuit components for maintenance and replacement. This design improves the convenience of maintenance and replacement. The detachable connection between the cover 112 and the box body 111 makes the production process simpler and more efficient. When assembling the circuit, it is only necessary to detachably connect the box body 111 and the cover 112 sealing cover without complicated fixing or welding operations.

[0074] Reference Figure 8In one embodiment, at least two second limiting portions 1121 are provided on the surface of the cover body 112 facing the opening 1111. The at least two second limiting portions 1121 are provided in one-to-one correspondence with at least two fuses 130. Each second limiting portion 1121 is used to abut against the fuse 130. In this way, the design of the second limiting portion 1121 can accurately position each fuse 130, ensure that the fuse 130 is in the correct position, and avoid installation errors or position deviations. Through the abutment between the second limiting portion 1121 and the fuse 130, the fuse 130 can be effectively restricted in the box body 111, and the fuse 130 can be prevented from exploding or being damaged due to overheating. The design of the second limiting portion 1121 can increase the safety of the entire circuit and prevent the fuse 130 from accidentally falling off and causing circuit failure or safety accidents. By providing the second stopper 1121, the installation process can be simplified, and the operator can more conveniently install the fuse 130 into the box body 111, thereby improving the installation efficiency. The design of the second stopper 1121 can make the connection between the fuse 130 and the box body 111 more flexible and convenient, thereby improving the interchangeability and adaptability of the circuit connector.

[0075] It should be noted that the present application does not limit the shape of the second limiting portion 1121, and the shape of the second limiting portion 1121 is adapted to the shape of the fuse 130, that is, in order to improve the limiting effect, the limiting portion has a contact side surface for contacting with the side surface of the fuse 130, and the shape of the contact side surface is adapted to the side wall surface of the fuse 130. For example, when the side wall surface of the fuse 130 is a cylinder, the contact surface is an arc surface adapted to the cylinder. That is, the size and shape of the second limiting portion 1121 can be adjusted to meet the needs of different fuses 130.

[0076] Reference Figures 3 to 5 In one embodiment, an input negative electricity wiring part 123 and at least two output negative electricity wiring parts 124 are further provided in the box body 110. The input negative electricity wiring part 123 and the at least two output negative electricity wiring parts 124 are arranged at intervals along the first direction. The input negative electricity wiring part 123 is used to be electrically connected to the input negative electricity wiring 213, and the at least two output negative electricity wiring parts 124 are used to be electrically connected to the at least two output negative electricity wiring parts 214. In this way, when wiring is realized, wiring is done from bottom to top, and wiring is convenient. The setting of the input negative electricity wiring part 123 and the at least two output negative electricity wiring parts 124 makes the wiring process more convenient and efficient. The operator can easily connect the input negative electricity wiring 213 and the output negative electricity wiring 214, reducing wiring time and cost. Due to the setting of the input negative electricity wiring part 123 and the at least two output negative electricity wiring parts 124, the circuit connection is clear and easy to see, and the operator can easily inspect, maintain and repair the circuit, thereby improving the reliability and safety of the circuit.

[0077] Among them, the wiring end face of the input negative power wiring part 123 is located below the wiring end face of the input positive power wiring part 121, and the wiring end face of the output negative power wiring part 124 is located below the wiring end face of the output positive power wiring part 122. In this way, the wiring end faces of the input negative power wiring part 123 and the output negative power wiring part 124 are arranged below the corresponding positive power wiring part, which can make full use of the space and make the entire circuit more compact and efficient. At the same time, it is also convenient for the wiring connection of the input negative power wiring 213, the output negative power wiring 214, the input positive power wiring 211 and the output positive power wiring 212. The wiring end faces of the input negative power wiring part 123 and the output negative power wiring part 124 are arranged below the corresponding positive power wiring part, which can effectively prevent the occurrence of safety problems such as wrong connection or accidental electric shock. When the circuit is connected, it can ensure that the distance between the negative power wiring and the positive power wiring is far, reduce the potential risk of short circuit, and improve the safety of the circuit. Since the connection end faces of the input negative power connection part 123 and the output negative power connection part 124 are arranged below the corresponding positive power connection part, the operator can conveniently inspect, maintain and repair the circuit. When it is necessary to replace the component, the corresponding connection can be disconnected and reconnected more easily, which improves the convenience of maintenance and replacement.

[0078] It should be noted that the at least two output negative power connection parts 124 can be arranged at intervals or in an integrated manner. Specifically, the present application does not limit this.

[0079] In addition, refer to Figure 4 The projections of the wiring end faces of the negative power input wiring part 123 and the wiring end faces of the positive power input wiring part 121 on the bottom surface of the box body are staggered, so that the potential risk of short circuit can be reduced and the safety of the circuit is improved. This design makes the production process simpler and more efficient. When assembling the circuit, it is only necessary to connect each wiring part in the correct position. When the circuit needs to be replaced or repaired, the corresponding wiring can be more easily disconnected and reconnected, which improves the convenience of maintenance and replacement. This design can make the circuit layout more compact and reduce the volume of the high-voltage distribution box 100.

[0080] In a second aspect, the present application further provides a vehicle, the vehicle comprising the high-voltage junction box 100 as described above.

[0081] According to the vehicle of the present application, short-circuit protection can be provided by setting at least two fuses 130 to ensure the safety of the circuit. One end of each fuse 130 is snap-fitted and fixed to the input positive electrical wiring portion 121, and the other end is snap-fitted and fixed to the corresponding output positive electrical wiring portion 122. In this way, the fuse 130 can be installed more conveniently and quickly without the need for additional tools or accessories, thereby reducing the difficulty of installation and improving the convenience of maintenance. By snapping the fuse 130 directly to the input positive electrical wiring portion 121 and the output positive electrical wiring portion 122, good contact can be ensured, contact resistance can be reduced, and the efficiency of current transmission can be improved. The snap-fitting and fixing method can be applied to fuses 130 of various specifications, so that the high-voltage junction box 100 has good versatility.
