Description

Technical Field

[0001] The utility model relates to the technical field of magnetic chargers, in particular to a wireless lecturer charger. Background Art

[0002] For exhibition halls, exhibition halls, museums, large corporate exhibition halls and tourist attractions with large flow of people, it is often necessary to charge wireless audio guides in batches to meet the needs of providing exhibit explanations to a large number of tourists and visitors.

[0003] Existing chargers designed for bulk charging of ear-hook wireless guides typically have multiple mounting slots on the cover of the charger housing. The current probes extending from the bottom of these slots need to be locked and aligned with the wireless guide via plastic latches on the cover to ensure contact and charging. These plastic latches are prone to structural wear during long-term, frequent charging and use, reducing the positioning accuracy of the wireless guides or even causing locking failure, which in turn prevents the wireless guides from charging. Consequently, the charger requires frequent replacement due to wear and tear, making it inconvenient to use and increasing maintenance costs.

[0004] At the same time, this type of charger usually has multiple slots at the edges of the cover corresponding to the mounting slots, and multiple clips matching the slots are provided on the bottom circumference of the plastic charging base. The clips engage with the slots to snap the charging base into and secure it to the corresponding mounting slots of the cover, achieving assembly of the charging base and the cover. The plastic clips used in this assembly method of the charging base and the cover are also prone to structural wear during long-term engagement with the clips, causing the charging base to require frequent replacement due to clip wear, which also makes the charger inconvenient to use and increases its maintenance cost. The cover needs to have multiple slots at the edges of the mounting slots, and the charging base needs to have multiple corresponding clips, which increases the manufacturing cost of the charging base. In addition, when assembling the charger, each clip needs to be aligned with the multiple slots one by one. When disassembling, the cover needs to be removed from the bottom shell first, and then each clip needs to be detached from the multiple slots one by one. This makes it inconvenient to assemble and disassemble the charging base and the cover, which is not conducive to quick maintenance and replacement of the charging base.

[0005] In addition, another type of existing charger uses a USB data cable to charge the wireless audio guide. During long-term and frequent plugging and unplugging of the data cable for charging, the USB socket of the charger is easily damaged. When charging a large number of wireless audio guides, it is easy to cause the work surface where the charger is placed to be filled with a large number of data cables, making the work surface messy. Due to the complicated wiring, some data cables may even become entangled or knotted, making the data cables easily damaged. Utility Model Content

[0006] The utility model provides a wireless lecturer charger to solve the technical problem that the existing chargers for batch charging without lecturers use plastic buckles to match the wireless lecturer and the current needle for positioning, and the plastic buckles are easily worn, resulting in failure of wireless lecturer positioning and poor charging contact.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is:

[0008] The utility model provides a wireless lecturer charger, comprising: a bottom shell; a cover plate, connected to the bottom shell to form a box body; a plurality of mounting slots, spaced apart on the cover plate; a plurality of notched slots are spaced apart on the slot walls of the mounting slots; the wireless lecturer charger also comprises:

[0009] The charging base includes: a base plate; a plug-in frame provided on the bottom surface of the base plate; a plurality of spring plates connected to the outer wall of the plug-in frame at intervals and angles and correspondingly matching the notched through slots; a positioning clip provided on the top surface of the base plate opposite to the plug-in frame, used to position and support the wireless lecturer; a mounting hole provided on the base plate and connecting the plug-in frame and the inner side of the positioning clip;

[0010] The magnetic charging head is embedded in the mounting hole;

[0011] The circuit sub-board is arranged in the plug-in frame and electrically connected to the bottom of the magnetic charging head;

[0012] A circuit main board is disposed in the bottom shell and electrically connected to each circuit sub-board;

[0013] When the charging base is inserted into the installation slot, each spring piece passes through the corresponding notch slot and abuts against the edge of the corresponding notch slot on the bottom surface of the cover plate, and cooperates with the base plate to clamp the cover plate up and down.

[0014] Preferably, the area of ​​the seat plate is larger than the area of ​​the mounting slot. When the charging base is inserted into the mounting slot, the seat plate is supported on the top surface of the cover plate and cooperates with the spring sheet below to clamp the cover plate.

[0015] The periphery of the seat plate is provided with clearance holes that match the spring pieces. The charging seat can be removed from the installation slot by passing multiple toggles through each clearance hole and toggling the corresponding spring pieces.

[0016] Preferably, the cover plate, the mounting slot, the seat plate and the plug-in frame are all rectangular, the four spring pieces are spaced apart on the outer wall at the four corners of the plug-in frame, and the four clearance holes are arranged at the four corners of the seat plate in a one-to-one matching manner with each spring piece.

[0017] Preferably, at least one alignment notch is provided at the top edge of the positioning snap ring.

[0018] Preferably, the inner side wall of the positioning snap ring is provided with at least one guide groove extending perpendicularly to the seat plate, and the top end of the guide groove passes through the top end edge of the positioning snap ring.

[0019] Preferably, the bottom shell is made of metal and the charging base is made of plastic.

[0020] Preferably, the bottom shell includes:

[0021] Base plate; shell frame connected to the top of the base plate;

[0022] A circle of supporting folding edges is arranged around the top end of the shell frame along its circumference, and the cover plate is connected to the top surface of the supporting folding edge.

[0023] Preferably, the inner side wall of the bottom shell is provided with at least one connecting column, the connecting column is provided with a threaded hole, the circuit main board is provided with a screw through-hole matching the threaded hole, and the circuit main board is installed in the bottom shell by connecting screws through the corresponding screw through-holes and threaded holes.

[0024] Furthermore, the wireless lecturer charger also includes:

[0025] The power interface and the data interface are spaced apart at the bottom shell corresponding to the circuit main board and are electrically connected to the circuit main board respectively.

[0026] Preferably, the wireless lecturer is an ear-hanging wireless lecturer, and the shape of the positioning clip matches the appearance of the ear-hanging wireless lecturer. The positioning clip is used to position and support the ear-hanging wireless lecturer and to align the charging part of the ear-hanging wireless lecturer with the magnetic charging head.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The wireless lecturer charger provided by the utility model adopts a positioning clip in its mounting slot to position and support the wireless lecturer. Compared with the traditional plastic buckle, the positioning clip has the advantages of thick ring wall and wear resistance, which can avoid the structural wear during long-term use, resulting in reduced positioning accuracy of the wireless lecturer or even inability to charge. Therefore, the charger and its mounting slot do not need to be replaced frequently, which facilitates the use of the charger and reduces its maintenance cost.

[0029] The positioning clip is matched with the alignment notch and guide groove to achieve precise guidance and positioning of the wireless lecturer. With the guidance support of the positioning clip and the magnetic positioning function of the magnetic charging head, the wireless lecturer and the magnetic charging head can be connected with high reliability and good contact, ensuring the charging effect of the wireless lecturer charger.

[0030] The wireless guide charger also uses a magnetic charging head with a positioning ring for precise magnetic positioning. This eliminates the need for numerous external data cables to charge wireless guides in bulk. Instead, cables are routed through the internal compartment of the box, between the corresponding circuit sub-boards of each charging station and between the sub-boards and the main circuit board within the box. This prevents damage to the charger's USB socket from frequent plugging and unplugging of cables, a cluttered work surface, and damage from entanglement of cables. The ample internal space also provides heat dissipation for the device.

[0031] In addition, during the assembly process of the charging base and the cover of the wireless lecturer charger, only the end of the spring piece needs to contact the bottom surface of the cover, avoiding the structural wear problem caused by the long-term cooperation of the traditional plastic clip and the card slot. Therefore, the charging base does not need to be replaced frequently, which makes the charger convenient to use and reduces maintenance costs. Moreover, the cover does not need to be provided with multiple card slots at the edge of the installation slot, and the charging base does not need to be provided with corresponding clips. Instead, only a spring piece with a simple structure needs to be provided to replace the clip and slot structure, thereby reducing the manufacturing cost of charging small electronic devices.

[0032] The wireless lecturer charger does not require the traditional assembly method of aligning each clip with multiple slots one by one. When disassembling the wireless lecturer charger, there is no need to first remove the cover plate from the bottom shell and then detach each clip from the multiple slots one by one. Instead, the toggle member can pass through each clearance hole and the corresponding notch slot, and then simultaneously toggle and squeeze the corresponding spring pieces, so that each spring piece is synchronously disengaged from the bottom surface of the cover plate. At this time, the charging base can be pulled upward until each spring piece passes through the corresponding notch slot and the clearance hole in sequence and exits above the base plate. The charging base can then be quickly removed from the mounting slot. Therefore, the small electronic device charging base and the cover plate provided by the utility model are easy to assemble and disassemble, convenient for maintenance and replacement, and improve the versatility of the wireless lecturer charger.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-10And embodiments, the utility model is further described in detail.

[0049] Please also refer to Figure 1-10 The wireless lecturer charger provided by the utility model includes:

[0050] A bottom shell 1; a cover plate 2, connected to the bottom shell 1 to form a box body, the cover plate 2 and the bottom shell 1 enclose an internal accommodating space 9 of the box body; a plurality of mounting slots 3, spaced apart on the cover plate 2, the mounting slots 3 passing through the oppositely disposed top and bottom surfaces of the cover plate 2, wherein the top surface of the cover plate 2 is the side of the cover plate 2 facing away from the internal accommodating space 9 of the box body, and the bottom surface of the cover plate 2 is the other side of the cover plate 2 facing the internal accommodating space 9 of the box body; a plurality of notched slots 4 are spaced apart on the groove walls of the mounting slots 3, the notches generally passing through the top and bottom surfaces of the cover plate 2;

[0051] The charging base 5 includes: a base plate 51; a plug-in frame 52, which is provided on the bottom surface of the base plate 51; a plurality of spring plates 53, which are spaced and obliquely connected to the outer wall of the plug-in frame 52, that is, the extension direction of the spring plates 53 forms an oblique angle of less than 90 degrees with the outer wall of the plug-in frame 52, and the positions of the plurality of spring plates 53 correspond to the positions of the respective notched through slots 4; a positioning snap ring 54, which is provided on the top surface of the base plate 51 relative to the plug-in frame 52, and the positioning snap ring 54 is located within the coverage area of ​​the area enclosed by the plug-in frame 52, for positioning and supporting the wireless lecturer (not shown in the figure); a mounting through hole 511, which is provided on the base plate 51 and connects the plug-in frame 52 and the inner side of the positioning snap ring 54, that is, the mounting through hole 511 is located at the overlapping area of ​​the base plate 51 enclosed by the plug-in frame 52 and the area enclosed by the positioning snap ring 54;

[0052] The magnetic charging head 6 is embedded in the mounting hole 511;

[0053] The circuit sub-board 7 is disposed in the plug-in frame 52 and electrically connected to the bottom of the magnetic charging head 6;

[0054] The main circuit board 8 is disposed in the bottom housing 1 and is electrically connected to each sub-circuit board 7 .

[0055] Please also refer to Figure 1 、 7 -10. In this embodiment, when each spring piece 53 is in an unstressed (uncompressed) initial position, the distance between its end away from the plug-in frame 52 and the seat plate 51 (i.e., the distance between the end of the spring piece 53 and the bottom surface of the seat plate 51) matches the thickness of the cover plate 2.

[0056] When the plug-in frame 52 at the bottom end of the charging seat 5 is inserted into the installation slot 3 from above the top surface of the cover plate 2 (the top surface of the cover plate 2 is facing away from the bottom surface of the cover plate 2), each spring piece 53 is squeezed and deformed from the initial position by the notch slot 4 in the process, until each spring piece 53 completely passes through and disengages from the corresponding notch slot 4. At this time, each spring piece 53 returns to its initial position under the action of elasticity, and its end abuts against the edge of the corresponding notch slot 4 on the bottom surface of the cover plate 2; at the same time, the seat plate 51 of the charging seat 5 is inserted to the position where the bottom surface of the seat plate 51 abuts the bottom surface of the cover plate 2, that is, when each spring piece 53 completely passes through and disengages from the corresponding notch slot 4, the charging seat 5 is inserted into the installation slot 3 in place. At this time, the seat plate 51 and the spring piece 53 cooperate up and down, so that the two respectively clamp the cover plate 2 from the top and bottom of the cover plate 2, thereby completing the quick and precise assembly of the charging seat 5 and the cover plate 2.

[0057] The wireless lecturer charger provided by the present invention has a charging base 5 that uses a positioning clip 54 to position and support the wireless lecturer. The positioning clip 54 has the advantages of thick ring wall and wear resistance compared to traditional plastic buckles, which can avoid structural wear during long-term use, resulting in reduced positioning accuracy of the wireless lecturer or even inability to charge. Therefore, the charger and the charging base 5 do not need to be replaced frequently, which makes the charger convenient to use and reduces its maintenance cost.

[0058] At the same time, the assembly between the charging base 5 and the cover plate 2 of the box body does not require a slot around the edge of the mounting slot 3 of the cover plate 2, nor does it require a buckle that matches the slot around the bottom side of the charging base 5. Instead, it only requires a simple spring piece 53 around the side of the plug-in frame 52 at the bottom end of the charging base 5, and a notched slot 4 that matches the position of the spring piece 53 on the wall of the mounting slot 3. When the charging base 5 is plugged into the mounting slot 3 through the plug-in frame 52, the spring piece 53 is first squeezed and deformed by the notched slot 4. Then, when the spring piece 53 is released from the notched slot 4 and the base plate 51 of the charging base 5 is inserted into place, the spring piece 53 automatically returns to its original position under the action of elasticity and abuts against the bottom surface of the cover plate 2. Thus, the base plate 51 and the spring piece 53 cooperate to clamp the cover plate 2 from top to bottom, completing the quick and precise assembly of the charging base 5 and the cover plate 2. Therefore, in the wireless lecturer charger provided by the present invention, during the assembly process of the charging base 5 and the cover plate 2, only the end of the spring piece 53 needs to contact the bottom surface of the cover plate 2, avoiding the structural wear problem caused by the long-term cooperation between the traditional plastic clip and the card slot. Therefore, the charging base 5 does not need to be replaced frequently, which makes the charger convenient to use and reduces maintenance costs. In addition, the cover plate 2 does not need to be provided with multiple card slots at the edge of the installation slot, and the charging base 5 does not need to be provided with corresponding clips. Instead, only a spring piece 53 with a simple structure needs to be provided to replace the clip and slot structure, thereby effectively reducing the manufacturing cost of the charging base 5.

[0059] Please also refer to Figure 1 、 4In this embodiment, the base plate 51 and the plug-in frame 52 are both centrally symmetrical and coaxially arranged. That is, their corresponding axes of symmetry coincide. The mounting hole 511 is located at the overlapping center of the area enclosed by the plug-in frame 52 on the base plate 51 and the center of the area enclosed by the positioning collar 54. In other words, the mounting hole 511 is located in the center of the base plate 51.

[0060] Please also refer to Figure 1 、 6 -10. In this embodiment, the area of ​​the circuit sub-board 7 is smaller than the area of ​​the area enclosed by the plug-in frame 52, and the bottom surface of the base plate 51 is provided with at least one mounting hole (not shown in the figure). The circuit sub-board 7 is provided with screw through holes (not shown in the figure) matching the mounting holes. The circuit sub-board 7 is fastened to the bottom surface of the base plate 11 by connecting screws (not shown in the figure) passing through the corresponding screw through holes and mounting holes, thereby installing the circuit sub-board 7 in the area enclosed by the plug-in frame 52.

[0061] As a preferred implementation of this embodiment, a boss (not shown in the figure) is provided on the bottom surface of the seat plate 51, and the boss is provided with the above-mentioned mounting hole.

[0062] As a more preferred implementation of this embodiment, two bosses and two screw holes are provided at intervals.

[0063] Please also refer to Figure 1 、 6 The top of the cover plate 2 is supported by the bottom plate 51 and the bottom plate 52 is supported by the bottom plate 51. The top of the cover plate 2 is supported by the bottom plate 51 and the bottom plate 52 is supported by the bottom plate 51.

[0064] Therefore, when assembling the wireless lecturer charger provided by the present invention, there is no need to adopt the traditional method of aligning and matching each clip with multiple slots one by one; when disassembling the wireless lecturer charger, there is no need to first remove the cover plate 2 from the bottom shell 1 and then detach each clip from the multiple slots one by one. Instead, the charging base 5 can be quickly removed from the installation slot 3 in the above-mentioned manner, thereby facilitating the disassembly and assembly of the charging base 5 and the cover plate 2, and facilitating the rapid maintenance and replacement of the charging base 5.

[0065] Please also refer to Figure 1-10 As a preferred implementation of this embodiment, the cover plate 2, the mounting slot 3, the base plate 51 and the plug-in frame 52 are all rectangular, and the four spring pieces 53 are spaced apart on the outer wall at the four corners of the plug-in frame 52. The four notched slots 4 are matched with each spring piece 53 and are arranged at the four corners of the mounting slot 3. The four clearance holes 512 are matched with each spring piece 53 and are arranged at the four corners of the base plate 51.

[0066] Please also refer to Figure 1 、 4 -10. In this embodiment, the inner sidewall of the longer side of the mounting hole 511 is parallel to the longer side of the cover plate 2, and the inner sidewall of the shorter side of the mounting hole 511 is parallel to the shorter side of the cover plate 2. Assuming that the longer side of the cover plate 2 extends in a first direction X and the shorter side of the cover plate 2 extends in a second direction Y perpendicular to the first direction X, the longer and shorter sides of the mounting hole 511 are respectively parallel to the first direction X and the second direction Y. The four notched slots 4 are divided into two groups, with two notched slots 4 in each group, respectively, provided at the ends of a pair of longer sides of the mounting slot 3 in the first direction X. The notched slots 4 are rectangular, with the longer base of the notched slots 4 parallel to the longer side of the mounting slot 3 (parallel to the first direction X). The pair of shorter sides of the notched slots 4 are respectively perpendicularly connected to the longer side of the mounting slot 3 and the longer base of the notched slot 4 in the first direction X. In other words, the pair of shorter sides of the notched slots 4 are parallel to the shorter side of the mounting slot 3 (parallel to the second direction Y).

[0067] Correspondingly, when the plug-in frame 52 is inserted into the mounting slot 3, the longer side of the base plate 51 of the charging station 5 is parallel to the longer side of the cover plate 2 (parallel to the first direction X), and the shorter side of the base plate 51 is parallel to the shorter side of the cover plate 2 (parallel to the second direction Y). When plugged into the mounting slot 3, two opposing side walls of the plug-in frame 52 of the charging station 5 are parallel to the longer side of the cover plate 2 (parallel to the first direction X), and the other two opposing side walls of the plug-in frame 52 are parallel to the shorter side of the cover plate 2 (parallel to the second direction Y).

[0068] Correspondingly, when the insertion frame 52 is inserted into the installation slot 3 and in place, the four clearance holes 512 are divided into two groups, with two clearance holes 512 in each group, respectively provided at both ends of a pair of longer edges of the base plate 51 in the first direction X. The clearance holes 512 are rectangular, with the pair of longer edges of the clearance holes 512 parallel to the longer edges of the cover plate 2 (parallel to the first direction X), and the pair of shorter edges of the clearance holes 512 parallel to the shorter edges of the cover plate 2 (parallel to the second direction Y).

[0069] Please also refer to Figure 1 、 4 -10, as a preferred implementation method of this embodiment, the inner side wall of the side of the displacement hole 512 away from the corresponding edge of the bottom plate 11 (that is, the inner side wall of the longer side of the displacement hole 512 away from the corresponding longer side of the bottom plate 11) is flush with the corresponding outer side wall of the plug-in frame 52 (that is, the outer side wall of the longer side of the plug-in frame 52), and the distance between the inner side wall of the side of the displacement hole 512 away from the corresponding edge of the bottom plate 11 and its opposite inner side wall (the distance between a pair of longer sides of the displacement hole 512 in the second direction Y) is greater than the width of the notch through groove 4 in the direction perpendicular to the groove wall of the corresponding installation through groove 3 (that is, greater than the longer bottom side of the notch through groove 4). The distance from the corresponding longer side of the mounting slot 3 in the second direction Y) is such that when the plug-in frame 52 is inserted into the mounting slot 3 and is in place, the clearance hole 512 completely covers the top of the notched slot 4, and the inner side wall of the clearance hole 512 close to the corresponding edge of the base plate 11 is located above the edge of the corresponding notched slot 4 of the cover plate 2. At this time, when the toggle member passes through the corresponding clearance hole 512 from the top of the seat plate 51 downward, due to the widened setting of the clearance hole 512, there is more angle adjustment space after the toggle member passes through each clearance hole 512 and the corresponding notched slot 4, so that the toggle member can perform the toggle and squeeze the corresponding spring piece 53 into place.

[0070] See also Figure 1 、 4As a preferred implementation manner of this embodiment, the distance between the other pair of inner side walls of the clearance hole 512 (i.e., the distance between a pair of shorter sides of the clearance hole 512 parallel to the second direction Y in the first direction X) is greater than the distance between the opposite side ends of the spring plate 53 in the first direction X, so that when the plug-in frame 52 is inserted into the installation slot 3 and is in place, the clearance hole 512 completely covers the notch slot 4 and the spring plate 53 below the notch slot 4, and a pair of gaps are formed between the two side ends of the spring plate 53 in the first direction X and the pair of shorter sides at both ends of the clearance hole 512 in the first direction X. Therefore, the toggle member can be extended into the gap formed between any end or both ends of the spring piece 53 in the first direction X and the shorter sides of the clearance hole 512 (at both ends in the first direction X), so that the toggle member can reach the back side of the spring piece 53 facing away from the seat plate 51, thereby completing the toggle member squeezing the back side of the spring piece 53, thereby pressing the spring piece 53 toward the plug-in frame 52, so that the spring piece 53 is out of contact with the bottom surface of the cover plate 2. At this time, the charging seat 5 can be pulled upward until the spring piece 53 passes through the corresponding notch slot 4 and the clearance hole 512 in turn and exits to the top of the seat plate 51, thereby quickly removing the charging seat 5 from the mounting slot 3.

[0071] In this embodiment, the toggle member may be a rod-shaped, tube-shaped, strip-shaped, hook-shaped or other shaped toggle member whose tip shape matches the shape of the clearance hole 512 and the notch groove 4 .

[0072] Please also refer to Figure 1 、 4 , 6, 8. In the present embodiment, the thickness direction of the cover plate 2 is the third direction Z, and the third direction Z is perpendicular to the first direction X and the second direction Y at the same time. Correspondingly, when the plug-in frame 52 of the charging stand 5 is inserted into the mounting groove 3 and is in place, the thickness direction of the base plate 51 of the charging stand 5 is parallel to the third direction Z, and the corresponding symmetry axes of the plug-in frame 52 and the positioning snap ring 54 of the charging stand 5 are parallel to the third direction Z, and the side walls of the plug-in frame 52 and the positioning snap ring 54 extend up and down relative to the base plate 51 in parallel with the third direction Z.

[0073] At least one alignment notch 541 is provided at the top edge of the positioning ring 54 (in the third direction Z), which is used to align the alignment notch 541 with the corresponding protrusion (such as a button, key, etc.) provided on the outer shell of the wireless lecturer when the positioning ring 54 positions and supports the wireless lecturer (such as an ear-hanging wireless lecturer), so as to achieve precise positioning of the wireless lecturer.

[0074] Please also refer to Figure 1 、 4, 6, 8. In this embodiment, the inner sidewall of the positioning clip 54 is provided with at least one guide groove 542 extending along a third direction Z perpendicular to the base plate 51 (the third direction Z is also perpendicular to the first direction X and the second direction Y). The top end of the guide groove 542 extends through the top edge of the positioning clip 54 (i.e., the top end of the guide groove 542 extends through the end of the positioning clip 54 away from the base plate 51 in the third direction Z). The location and extension direction of the guide groove 542 match the location and extension direction of corresponding protrusions, ribs, and other structures on a wireless lecturer (such as an ear-hanging wireless lecturer) to further achieve precise positioning of the wireless lecturer.

[0075] By combining the positioning snap ring 54 with the alignment notch 541 and the guide groove 542, the wireless lecturer can be accurately guided and positioned. With the guidance and support function of the positioning snap ring 54 and the magnetic positioning function of the magnetic charging head 6, the wireless lecturer and the magnetic charging head 6 can be docked with high reliability and good contact, thereby ensuring the charging effect of the wireless lecturer charger.

[0076] The wireless lecturer charger also uses a magnetic charging head 6 in conjunction with a positioning ring 54 for precise magnetic positioning and charging. This eliminates the need for numerous external data cables to charge wireless lecturers in bulk. Instead, the cables are routed between the corresponding circuit sub-boards 7 of each charging station 5, and between the sub-boards 7 and the main circuit board 8 within the box.
