Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a power supply box and a lighting system equipped with the power supply box. Background Technology

[0002] Currently, power supply boxes on the market are mainly divided into two categories: economy and professional. Economy power supply boxes mainly consist of a box body, a bottom cover, and a power module. The box body and the bottom cover are connected by a snap-fit ​​structure, and the power module is installed in the space enclosed by the box body and the bottom cover. The shortcomings of existing economy power supply boxes are that additional cable clips are required to improve the tensile strength of the cables connected to the power module, which makes installation troublesome and costly.

[0003] The professional power supply box is an upgrade from the economy power supply box, mainly by adding an end cover. The end cover is fixed to the box body with bolts so that the end cover can clamp the cable connected to the power module, thereby ensuring the tensile strength of the cable. The box body and bottom cover of the professional power supply box are still connected by a snap-fit ​​structure.

[0004] The existing power supply box 9 has a snap-fit ​​connection structure between the box body 91 and the bottom cover 92 as follows: Figure 1 As shown, the inner wall 911 of the box body 91 has a recessed groove 9111, and the bottom cover 92 is provided with a buckle 921 that cooperates with the groove 9111. However, the existing buckle connection structure design between the box body 91 and the bottom cover 92 has the following shortcomings: In order to ensure the firmness of the connection between the box body 91 and the bottom cover 92, the groove 9111 needs to have sufficient depth to cooperate with the buckle 921. When the depth of the groove 9111 increases, the wall thickness of the box body 91 will be greater, which will lead to an increase in the material used in the box body 91 and an increase in cost. Summary of the Invention

[0005] To address the aforementioned issues, the main objective of this utility model is to provide a power box with a small overall wall thickness and a reliable snap-fit ​​connection between the box body and the bottom cover.

[0006] Another objective of this invention is to provide a lighting system equipped with the aforementioned power supply box.

[0007] To achieve the main objective of this utility model, this utility model provides a power supply box, including a box body, a bottom cover, and a power module. The box body has a receiving cavity, and the bottom cover covers the opening of the receiving cavity. The power module is installed in the receiving cavity. The inner wall of the box body has a boss near the opening. A groove is recessed on the protruding end face of the boss. A relief groove is recessed on the bottom cover at the boss. A buckle is formed on the bottom surface of the relief groove facing the protruding end face. At least a portion of the boss is located in the relief groove, and the buckle is engaged in the groove.

[0008] As can be seen from the above, by thickening the local side wall of the box body with a boss and setting a slot on the boss, the slot and the buckle on the bottom cover have sufficient mating depth, ensuring the tightness and reliability of the connection between the box body and the bottom cover. In addition, this design can reduce the overall wall thickness of the box body, saving the production materials and costs of the box body while ensuring the strength of the box body.

[0009] A preferred embodiment is that the boss surrounds the outer periphery of the slot; and / or the side of the boss facing the opening is provided with a guide ramp, the guide ramp being inclined away from the first sidewall where the boss is located and extending inclined towards the bottom of the receiving cavity.

[0010] As can be seen above, the guide ramp helps the buckle to pass over the edge of the boss to engage with the slot, making the installation of the box and the bottom cover easier and more convenient.

[0011] Another preferred embodiment is that the box body is provided with a slot that penetrates the top of the box body in the height direction and communicates with the receiving cavity. The slot is provided with two first engaging parts, each of which includes a plurality of first engaging teeth distributed in the height direction. The second side wall of the box body is provided with a through first clearance opening at the slot, and the two first engaging parts are located on both sides of the first clearance opening. The power supply box also includes an end cover, which is provided with a second clearance opening and two second engaging parts. The two second engaging parts are located on both sides of the second clearance opening, and each second engaging part includes at least one second engaging tooth. The end cover is detachably inserted into the slot, and the second engaging tooth can engage with the first engaging tooth. The second clearance opening is directly opposite the first clearance opening.

[0012] As can be seen from the above, the end cap is used to clamp and fix the cable connected to the power module in conjunction with the bottom box, thereby improving the cable's resistance to push and pull and preventing the cable from detaching from the power module; the first clearance opening and the second clearance opening are used to allow the cable to pass through the box, which also helps the end cap and the bottom box to clamp and fix the cable; and the end cap, through the engagement of the first engagement part and the second engagement part, makes the relative position between the end cap and the bottom box adjustable and easy to adjust, so that the end cap and the bottom box can clamp and fix cables of different diameters, expanding the applicability of the power box and improving its practicality.

[0013] A further design includes a first clamping part located within the slot, situated at the first clearance opening; the opening of the second clearance opening faces the bottom cover, and a second clamping part is located at the bottom of the second clearance opening, forming a clamping position between the first clamping part and the second clamping part.

[0014] As can be seen from the above, the cooperation between the first clamping part and the second clamping part helps to better clamp and fix the cable, and improve the cable's resistance to push and pull.

[0015] A further improvement is that the top of the first clamping part has a first serrated structure, and the side of the second clamping part facing the bottom cover has a second serrated structure.

[0016] As can be seen from the above, the serrated structure can increase the friction between the first clamping part, the second clamping part and the cable surface, thereby further improving the cable's resistance to push and pull.

[0017] Another further solution is to provide a limiting plate at the bottom of the box at the slot, and the limiting plate has a through-hole at the mating part of the first engaging part and the second engaging part.

[0018] As can be seen from the above, the limiting plate can limit the end cover, preventing the end cover from moving excessively towards the bottom cover and causing the cable to be excessively squeezed and damaged. At the same time, the limiting plate can provide space for the socket, avoiding unnecessary drilling of the power module's base plate and ensuring the reliability of the power module. In addition, the socket design makes it easy for users to control the separation of the first and second locking parts, making the disassembly and removal of the end cover from the box more convenient and easier.

[0019] A further proposed solution involves two slots, distributed along the length of the box at both ends, with two first engaging portions within the slots distributed along the width of the box; two end caps, each corresponding to one of the two slots; and recessed portions at both ends of the box, extending from the ends of the box into the receiving cavity along the length, with the recessed portions and slots distributed along the width. A limiting plate extends along the width to the recessed portion, and the limiting plate also has a through-hole connecting slot in the recessed portion.

[0020] As can be seen from the above, since the power supply box needs to be connected to the power supply cable and also needs to be electrically connected to the light fixture through the connecting cable, the structural layout of the power supply box can be effectively optimized by designing the number of slots and end caps, the routing of the power supply cable and connecting cable, and making the wiring of the power supply box safer, while ensuring that the power supply box meets the safety specifications; the setting of the connecting slot hole makes the installation of the power supply box more convenient.

[0021] A further proposed solution is that the top contour of the end cap is similar to the top contour of the box body, and the top of the end cap is provided with a pressing protrusion and / or a pressing recess. When the end cap is provided with a pressing protrusion and a pressing recess, the pressing protrusion is located in the pressing recess; and / or the bottom cover is provided with an elastic buckle at the limiting plate, the elastic buckle having a claw end that can be engaged with the limiting plate.

[0022] As can be seen from the above, the design of the pressing protrusion and / or pressing recess makes it more convenient for users to move the pressing end cap to the bottom cover and is less likely to slip; the addition of an elastic buckle on the bottom cover to cooperate with the limiting plate can further make reasonable use of the structure of the box and make the connection between the bottom cover and the box more secure.

[0023] A further solution is to have a set of supporting ribs and limiting ribs inside the cavity, and a limiting groove through which the power module's base plate is provided, with the limiting ribs inserted into the limiting groove, and the base plate being clamped and fixed between the supporting ribs and the bottom cover; and / or a laser-engraved identification point is provided on the top of the box.

[0024] As can be seen from the above, the supporting ribs and the base plate work together to clamp and fix the power module base plate to prevent the power module from moving around in the power box. The limiting ribs and the upper limit groove design of the base plate can play a foolproof role, ensuring the accuracy of the power module installation position and improving the assembly efficiency of the power module. This avoids incorrect wiring when users perform wiring in the future, and ensures the safety of the power supply and its use.

[0025] To achieve another objective of this utility model, this utility model provides a lighting system, including a lamp, the lamp including a light source, wherein the lighting system further includes the aforementioned power supply box, and the light source is electrically connected to the power supply module.

[0026] As can be seen from the above, by setting up the aforementioned power box, the lighting system achieves lower costs, easier wiring, and greater product reliability. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0041] Power supply box embodiment

[0042] Reference Figure 2 and Figure 3 The power supply box 100 includes a box body 1, a bottom cover 2, a power module 3, and an end cover 4.

[0043] Combination Figure 4 The box body 1 has a receiving cavity 11 for accommodating the bottom cover 2, power module 3, etc. A boss 12 is provided on the inner wall of the receiving cavity 11, and the boss 12 is located near the opening 111 of the receiving cavity 11. In this example, the boss 12 is preferably located on the side wall of the box body 1 distributed along the width direction of the box body 1. It is understood that in some embodiments, the boss 12 may also be located on the side wall of the box body 1 distributed along the length direction of the box body 1. The boss 12 is provided with a groove 121, which is recessed into the boss 12 from its protruding end face in the width direction of the box body 1.

[0044] Combination Figure 5 and Figure 6 The bottom cover 2 is detachably connected to the box body 1. When the bottom cover 2 is installed on the box body 1, the bottom cover 2 covers the opening 111 of the receiving cavity 11 to seal the opening 111 of the receiving cavity 11, prevent external dust from entering the receiving cavity 11 and contaminating the power module 3, and effectively ensure that the power module 3 can work normally, stably and safely.

[0045] The bottom cover 2 is provided with a relief groove 21 at each protrusion 12. In this embodiment, the relief groove 21 does not penetrate the bottom cover 2 in the height direction of the box body 1, so that when the bottom cover 2 is assembled with the box body 1, the relief groove 21 is used to accommodate the protrusion 12 and can limit the protrusion 12 to prevent the bottom cover 2 from moving excessively into the receiving cavity 11. A buckle 22 is formed on the bottom surface of the relief groove 21 facing the protruding end face of the protrusion 12. When the bottom cover 2 is assembled with the box body 1, at least a part of the protrusion 12 is located in the relief groove 21, so that the buckle 22 is engaged in the buckle groove 121, thereby realizing the fixed connection between the bottom cover 2 and the box body 1.

[0046] By providing a protrusion 12 on the inner wall of the box body 1 and placing a slot 121 on the protrusion 12, the protrusion 12 locally thickens the side wall of the box body 1, thereby ensuring that the slot 121 has sufficient depth to engage with the buckle 22 on the bottom cover 2, thus ensuring the tightness and reliability of the connection between the box body 1 and the bottom cover 2. Furthermore, due to the presence of the protrusion 12, the overall wall thickness of the box body 1 can be reduced. Therefore, compared to existing power box bodies, while ensuring the strength of the box body 1 meets requirements, the overall thickness of the box body 1 of this invention can be thinner, such as the thickness at the thinnest point being less than or equal to 1.2 mm, thus saving materials and reducing production costs.

[0047] In some embodiments, the boss 12 surrounds the outer periphery of the slot 121, making the forming of the boss 12 and the slot 121 more convenient, which helps to reduce the structural complexity of the mold for producing the box body 1, thereby reducing production costs; at the same time, this design also helps to ensure the structural strength of the side wall of the box body 1 at the boss 12, and avoids cracking of the box body 1 at the boss 12 due to the assembly or separation between the slot 121 and the buckle 22.

[0048] In some embodiments, the side of the boss 12 facing the opening 111 of the receiving cavity 11 is provided with a guide slope 122. The guide slope 122 extends away from the first sidewall where the boss 12 is located and slopes towards the bottom of the receiving cavity 11. Through the guide slope 122, during assembly of the box body 1 and the bottom cover 2, the buckle 22 can more smoothly pass over the edge of the boss 12 and engage with the slot 121, thereby making the installation of the box body 1 and the bottom cover 2 easier and more convenient. Furthermore, a slope that engages with the guide slope 122 can also be provided on the buckle 22 to further simplify and facilitate the assembly of the box body 1 and the bottom cover 2.

[0049] In this embodiment, the power supply box 100 includes an end cap 4; therefore, the box body 1 is provided with a slot 13 and a first clearance opening 14. The slot 13 penetrates the top of the box body 1 in the height direction and communicates with the receiving cavity 11. The first clearance opening 14 is located on the second side wall of the box body 1, and the second clearance opening 41 penetrates the second side wall, so that the first clearance opening 14 communicates with the slot 13. In this embodiment, the second side wall is adjacent to the first side wall where the boss 12 is located; however, it is understood that in other embodiments, the first side wall and the second side wall may also be the same side wall. The end cap 4 is used to cooperate with the box body 1 to clamp and fix the cable 10 connected to the power module 3, so as to improve the resistance of the cable 10 to push and pull, thereby preventing the cable 10 from detaching from the terminal 32 of the power module 3; the first clearance opening 14 is used to allow the cable 10 to pass through the power supply box 100, so that the cable 10 can be electrically connected to the terminal 32 of the power module 3 inside the power supply box 100.

[0050] The slot 13 is provided with two first engaging portions 131, which are located on both sides of the first clearance opening 14, so that the first clearance opening 14 is approximately located between the two first engaging portions 131. The first engaging portion 131 includes a plurality of first locking teeth 1311, which are distributed along the height direction of the box body 1.

[0051] Combination Figures 7 to 10 The end cap 4 is detachably installed in the slot 13. The top contour of the end cap 4 is similar to the top contour of the box body 1, so that when the end cap 4 is installed on the box body 1, the overall contour of the power box 100 is harmonious and not obtrusive, thereby increasing the overall aesthetics of the power box 100. The power box 100 is provided with a second clearance opening 41 and two second engaging portions 42. The two second engaging portions 42 are located on both sides of the second clearance opening 41, so that the second clearance opening 41 is approximately located between the two second engaging portions 42. The opening of the second clearance opening 41 faces the bottom cover 2, so that when the end cap 4 is installed, the cable 10 connected to the power module 3 can pass through the opening into the second clearance opening 41. The second engaging portion 42 is used to cooperate with the first engaging portion 131. The second engaging portion 42 includes at least one second locking tooth 421, which can engage with the first locking tooth 1311 of the first engaging portion 131.

[0052] In this embodiment, the second engaging portion 42 includes a plurality of second engaging teeth 421, which are distributed along the height direction of the housing 1. The number of second engaging teeth 421 and first engaging teeth 1311 may be equal or unequal. When the end cover 4 is assembled with the housing 1, the second clearance opening 41 faces the first clearance opening 14, allowing the cable 10 connected to the power module 3 to pass through the second clearance opening 41 and the first clearance opening 14 to extend into the power box 100 and electrically connect to the wiring terminal 32 of the power module 3. The second engaging teeth 421 engage with the first engaging teeth 1311. It can be understood that at this time, some of the second engaging teeth 421 near the bottom of the power box 100 first engage with some of the first engaging teeth 1311 near the top of the power box 100. During engagement, one second locking tooth 421 engages with one first locking tooth 1311. Based on this, it can be seen that when the wire diameter of the cable 10 is different, the number of second locking teeth 421 engaging with the first locking tooth 1311 is also different. That is, the number of second locking teeth 421 engaging with the first locking tooth 1311 is not absolute. It is possible that all the second locking teeth 421 can engage with the corresponding first locking tooth 1311, or it is possible that only some of the second locking teeth 421 can engage with the corresponding first locking tooth 1311.

[0053] By providing an end cap 4, the end cap 4 can clamp and fix the cable 10 in conjunction with the box body 1. The end cap 4 engages with the first engaging part 131 and the second engaging part 42, making the relative position between the end cap 4 and the box body 1 adjustable and easy to adjust. This allows the end cap 4 and the box body 1 to clamp and fix cables 10 of different diameters, expanding the applicability of the power box 100 and improving its practicality. Furthermore, thanks to the action of the first engaging part 131 and the second engaging part 42, the assembly of the end cap 4 and the box body 1 does not require additional bolts, effectively reducing the cost of the power box 100. Therefore, considering the combined structural design of the box body 1, bottom cover 2, and end cap 4, the cost of the power box 100 provided by this utility model is close to that of existing economical power boxes, while its performance is superior to existing professional power boxes.

[0054] To improve the reliability of the clamping and fixing of the cable 10 between the end cap 4 and the housing 1, and to enhance the resistance of the cable 10 to push and pull, a first clamping part 132 can be provided in the slot 13. The first clamping part 132 is located at the first clearance opening 14. Correspondingly, a second clamping part 411 can be provided at the bottom of the second clearance opening 41 of the end cap 4. A clamping position can be formed between the first clamping part 132 and the second clamping part 411, so that when the housing 1 and the end cap 4 are assembled, the cable 10 can be reliably clamped and fixed by the cooperation of the first clamping part 132 and the second clamping part 411.

[0055] Furthermore, as in this embodiment, the first clamping part 132 is formed with a first serrated structure 1321, and correspondingly, the second clamping part 411 has a second serrated structure 4111 on the side facing the bottom cover 2. The first serrated structure 1321 can increase the friction between the first clamping part 132 and the surface of the cable 10. Similarly, the second serrated structure 4111 can increase the friction between the second clamping part 411 and the surface of the cable 10, thereby enabling the first clamping part 132 and the second clamping part 411 to clamp and fix the cable 10 more reliably, and improving the cable 10's resistance to push and pull.

[0056] Furthermore, in this embodiment, a limiting plate 15 is provided at the slot 13 at the bottom of the box body 1. The limiting plate 15 has an insertion port 151 at the mating point of the first engaging portion 131 and the second engaging portion 42. The insertion port 151 extends through the limiting plate 15 in the height direction of the box body 1. It can be understood that, in the height direction, the projection of the mating point of the first engaging portion 131 and the second engaging portion 42 is located at the projection of the insertion port 151, or the mating point of the first engaging portion 131 and the second engaging portion 42 overlaps with the projection of the insertion port 151. First, the limiting plate 15 can limit the end cover 4 to prevent the end cover 4 from moving excessively toward the bottom cover 2, which would cause the cable 10 to be excessively squeezed and damaged. Second, the limiting plate 15 can provide space for the setting of the socket 151, avoiding unnecessary opening of the base plate 31 of the power module 3, thus ensuring the reliability of the power module 3. In addition, the socket design makes it easy for the user to control the separation of the first engaging part 131 and the second engaging part 42, so that the bottom cover 2 does not need to be disassembled when the end cover 4 is removed, simplifying the disassembly steps of the end cover 4.

[0057] Since the power supply box 100 needs to be connected to the power supply cable 10, and the power supply box 100 also needs to be electrically connected to the lamp via the connecting cable 10, in this embodiment, the number of slots 13 is set to two, and the two slots 13 are distributed at both ends of the box body 1 along the length direction of the box body 1. The two first engaging portions 131 within the slots 13 are distributed along the width direction of the box body 1. Correspondingly, the number of end caps 4 is also set to two, and the two end caps 4 correspond one-to-one with the two slots 13. By designing the number of slots 13 and end caps 4, and the position of the slots 13, the structural layout of the power supply box 100 can be effectively optimized, the wiring layout of the power supply cable and connecting cable can be optimized, and the wiring of the power supply box 100 can be made safer, while ensuring that the power supply box 100 meets safety specifications. Of course, in other embodiments, the number of slots 13 and end caps 4 can also be one.

[0058] In this embodiment, the two ends of the box body 1 are respectively provided with inner groove portions 16. The inner groove portions 16 are recessed into the receiving cavity 11 from the end of the box body 1 in the length direction, and the inner groove portions 16 and the slots 13 are distributed along the width direction of the box body 1. The limiting plate 15 extends to the inner groove portion 16 in the width direction. The limiting plate 15 is also provided with a connecting slot 152 in the inner groove portion 16. The connecting slot 152 penetrates the limiting plate 15 in the height direction of the box body 1. Since the wiring terminal 32 of the power module 3 is located in the slot 13 when the power module 3 is installed in the box 1, and the first engaging part 131 is located between the first clearance opening 14 and the wiring terminal 32; therefore, in order to make the overall structural layout of the power module 3 more regular and reasonable, in the width direction of the box 1, the power module 3 will not have related electronic components and substrate structures on the side of the first engaging part 131. The design of the above-mentioned recessed part 16 is based on the characteristics, making full use of the internal redundant space of the receiving cavity 11 and the structure of the power module 3, avoiding the need to set an additional external connecting ear structure for the setting of the connecting slot 152, thereby effectively reducing the space occupied by the power box 100 and optimizing the overall structural layout of the power box 100.

[0059] Furthermore, see Figure 5 and Figure 8 Based on the limiting plate 15 provided on the box body 1, the bottom cover 2 can also be provided with an elastic buckle 23 at the limiting plate 15. The elastic buckle 23 has a claw end 231 facing the limiting plate 15. When the bottom cover 2 is assembled with the box body 1, the claw end 231 can be fastened on the limiting plate 15. This design can further make reasonable use of the structure of the box body 1, which not only improves the reliability of the connection between the bottom cover 2 and the box body 1, but also does not cause the wall thickness of the box body 1 to increase.

[0060] Furthermore, the top of the end cap 4 is provided with pressing protrusions 44 and / or pressing recesses 43. As in this embodiment, the top of the end cap 4 is provided with pressing protrusions 44 and pressing recesses 43. The pressing recesses 43 are recessed from the top of the end cap 4 toward the bottom cover 2. There are multiple pressing protrusions 44, which are distributed in a roughly parallel manner within the pressing recesses 43. The outer contours of the top of the multiple pressing protrusions 44 are similar to the outer contours of the top of the end cap 4 to ensure the overall coordination of the end cap 4 and the power box 100. The design of the pressing protrusions 44 and / or pressing recesses 43 makes it more convenient for the user to move the end cap 4 toward the bottom cover 2 and prevents slippage.

[0061] In some embodiments, the top of the end cap 4 may not have the pressing protrusion 44 and the pressing recess 43, such as... Figure 11 As shown in (a).

[0062] In some embodiments, the top of the end cap 4 is only provided with a pressing recess 43, such as Figure 11 As shown in (b).

[0063] In some embodiments, the top of the end cap 4 is also provided with a pressing protrusion 44 and a pressing recess 43, but the pressing protrusion 44 has a circular structure, and the top contour of the pressing protrusion 44 may not be similar to the top contour of the end cap 4, such as... Figure 11 As shown in (c).

[0064] Furthermore, the receiving cavity 11 is provided with a support rib assembly 112 and a limiting rib 113. The base plate 31 of the power module 3 is provided with a limiting groove 311 that penetrates itself. When the power module 3 is assembled with the housing 1, the power module 3 is supported on the support rib assembly 112, and the limiting rib 113 is inserted into the limiting groove 311. When the bottom cover 2 is assembled with the housing 1, the base plate 31 is clamped and fixed between the support rib assembly 112 and the bottom cover 2 to prevent the power module 3 from moving around in the power box 100. The design of the limiting rib 113 and the limiting groove 311 on the base plate 31 can play a foolproof role, ensuring the accuracy of the installation position of the power module 3 and improving the assembly efficiency of the power module 3. It also avoids incorrect wiring by the user during subsequent wiring, ensuring the safety of the power supply.

[0065] In some embodiments, the top of the box body 1 is provided with a laser engraving identification point 17, so as to provide a positioning base point for the processing equipment when laser engraving is performed on the top of the box body 1.

[0066] In some embodiments, the design of the slot 13, the first clearance opening 14, the limiting plate 15, and the inner groove 16 of the box body 1 can be omitted. Correspondingly, the design of the end cover 4 of the power supply box 100 can be omitted, and the design of the elastic buckle 23 on the bottom cover 2 can be omitted. In this case, if it is necessary to provide a connecting slot 152, a connecting ear can also be provided on the bottom of the outer periphery of the box body 1, and a connecting slot 152 can be provided on the connecting ear.
