Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a power signal box and signal device. Background Technology

[0002] With the continuous development of LED display technology, LED displays have been widely used in various fields such as indoor advertising and conference presentations. Currently, a typical indoor LED display consists of multiple display units. The display unit usually adopts an integrated cabinet structure design, that is, the core components such as the display module, power supply, signal receiving card and adapter board are integrated and installed in the same cabinet to form a fixed display unit.

[0003] However, in the aforementioned LED display units, the number and arrangement of display modules are fixed in the cabinet structure before leaving the factory, resulting in a relatively fixed physical size that a single display unit can display, which cannot be flexibly adjusted according to actual application scenarios. Secondly, the cabinet structure is highly integrated, making disassembly and maintenance inconvenient. Once any internal component, display module, or adapter board malfunctions, it often requires complete disassembly or replacement, increasing the cost and difficulty of subsequent maintenance. Utility Model Content

[0004] One objective of this invention is to solve the problems of fixed size, difficulty in expanding display modules, inconvenient maintenance, and high cost in traditional LED display units. In response, this invention provides a power signal box that allows users to connect display modules flexibly and stably according to their own needs.

[0005] Another objective of this invention is to provide a signal device including the aforementioned power signal box.

[0006] A power signal box, which is electrically connected to a display module via a data connection cable, the power signal box comprising: The box body has multiple insertion holes on at least one side surface, and the edge contours of the insertion holes on opposite sides are respectively convex. The main control board is located inside the housing and integrates at least a switching module and a receiving module. Multiple sockets are disposed on the main control board and electrically connected to the main control board respectively. Each socket corresponds to a plug hole so that an external data connection cable can be plugged into the socket through the plug hole.

[0007] In some embodiments of this application, the plurality of insertion holes on the same side of the housing are interconnected.

[0008] In some embodiments of this application, the plug hole includes a main body area, a first hole area, and a second hole area. The socket corresponds to the main body area. The first hole area and the second hole area are located on opposite sides of the main body area, and the first hole area and the second hole area are respectively connected to the main body area. The edge contour of the first hole area is convex, the edge contour of the second hole area is convex, and the edge contours of the first hole area and the edge contours of the second hole area are arranged in a mirror symmetrical manner along the center line of the main body area.

[0009] In some embodiments of this application, the socket is a reversible plug-in socket.

[0010] In some embodiments of this application, the main control board also integrates a power module.

[0011] In some embodiments of this application, the power signal box includes a power module disposed within the box body. The power module includes a fixing member, an isolation plate, and multiple conductive sheets. The conductive sheets are provided with through holes, and the main control board is provided with via holes. The fixing member passes through the through holes and the via holes to realize the electrical connection between the power module and the main control board. The isolation plate is provided between each pair of adjacent conductive sheets, and the main control board is provided with a groove, in which the isolation plate is accommodated.

[0012] In some embodiments of this application, the power signal box includes a transmitting signal socket, a receiving signal socket, and a power socket, which are disposed on the main control board.

[0013] In some embodiments of this application, a plurality of spaced heat dissipation ribs are provided on one side of the box body, and the main control board is attached to the inner surface of the side of the box body where the heat dissipation ribs are provided.

[0014] In some embodiments of this application, the box body includes a box base and an extension. One end of the extension is connected to the box base, and the other end extends beyond the end face of the box base. The extension is provided with mounting holes, through which external fasteners can fix the power signal box to the external frame.

[0015] A signal device includes a data connection cable and a power signal box as described above. The data connection cable includes a cable body and a connector disposed at one end of the cable body. The connector includes: A connector that can pass through a plug hole on the signal connector and be adapted to be inserted into a socket; The snap-fit ​​structure includes an elastic part and a pressing part connected to the elastic part. The elastic part is elastic, and when an external force is applied to the pressing part, the elastic part can undergo elastic deformation, so that the pressing part can be relatively close to the connector and can extend into the power signal box from the U-shaped part of the upper edge of the insertion hole. When the external force is released, the elastic part returns to its original deformation, so that the pressing part is relatively away from the connector and can abut against the inner wall of the power signal box, so that the snap-fit ​​structure is snapped and fixed to the box body.

[0016] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: This utility model discloses a power signal box, comprising a box body, a main control board, and sockets. The sockets are electrically connected to the main control board and correspond to the insertion holes on the box body, allowing external data cables to be plugged into the sockets through the insertion holes. Multiple sockets are provided, thus one power signal box can connect to multiple display modules via multiple data cables; the specific number of display modules can be flexibly set according to actual needs.

[0017] It is understandable that the power signal box in this application is independent of the display module, which facilitates maintenance. Furthermore, one power signal box can connect multiple display modules simultaneously, and the main control board inside the power signal box integrates at least an adapter module and a receiver module. Compared to the situation where multiple LED display units with an integrated cabinet structure are electrically connected, where each LED display unit has its own receiver card and adapter board, the power signal box in this application effectively saves the cost of setting up multiple receiver cards and multiple adapter boards.

[0018] Furthermore, the plug holes on the power signal box have convex U-shaped edges on both sides, which can cooperate with external data connection cables to effectively ensure a stable connection between the power signal box and the data connection cable, and facilitate stable transmission of signals and / or power.

[0028] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0029] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] This utility model provides a power signal box 100, which can be electrically connected to a display module via a data connection line to realize the control of the display module.

[0032] Please see Figure 1 and Figure 2 The power signal box 100 includes a box body 1 and a main control board 2. The main control board 2 is located inside the box body 1. The box body 1 provides protection for the main control board 2, preventing it from being exposed to the outside and easily damaged.

[0033] It should be noted that the outer contour of the box 1 in this embodiment is approximately cuboid. In other embodiments, the outer contour of the box 1 may also be other shapes, such as cylinder, cube, hexagon, or other irregular shapes.

[0034] See Figure 3 and Figure 4 In some embodiments, the box body 1 may include a lid 11 and a base 12. The base 12 and the lid 11 enclose the box body 1. The base 12 and the lid 11 may be detachably connected to facilitate the user's inspection and replacement of components installed inside the box body 1.

[0035] See Figure 3The cover 11 can be screwed onto the base 12. Specifically, in this embodiment, the base 12 includes a base plate 121, peripheral side plates 122, and mounting posts 123. Four peripheral side plates 122 are provided, each located on one side of the base plate 121. The four peripheral side plates 122 are connected end-to-end, forming a ring structure. One end of the mounting post 123 is located on the base plate 121, and the end of the mounting post 123 facing away from the base plate 121 has a connecting hole 124. The cover 11 has a corresponding assembly hole 111. The box body 1 includes a mounting component. The mounting component passes through the assembly hole 111 on the cover 11 and is accommodated in the connecting hole 124 to mount the cover 11 onto the base 12. The mounting component can be a screw, bolt, etc.

[0036] It is understandable that in other embodiments, the detachable connection between the cover 11 and the base 12 can also be a snap-fit, magnetic connection, etc. It should be noted that, compared with other detachable connection methods, screw connection is more reliable. Even if the power signal box 100 is pulled by external force or dropped, the cover 11 and the base 12 are not easily separated.

[0037] See Figure 4 In some embodiments, the housing 1 includes an extension 13, one end of which is connected to the housing base 12, and the other end extends beyond the end face of the housing base 12. A mounting hole 131 is provided on the end of the extension 13 extending beyond the end face of the housing base 12. External fasteners can fix the power signal box 100 to the external frame through the mounting hole 131. The fasteners can be screws, bolts, etc.

[0038] For example, two extensions 13 are provided, respectively located at opposite ends of the housing 12, so that the power signal box 100 can be more stably mounted on the external frame.

[0039] The extension 13 can be disposed on the base plate 121 in the box base 12; or, the extension 13 can be disposed on the peripheral side plate 122 in the box base 12; or, as... Figure 4 As shown, the base plate 121 and one of the peripheral side plates 122 of the box base 12 are provided with extensions 13. The extensions 13 on the base plate 121 and the extensions 13 on the peripheral side plates 122 are arranged at an angle, thereby expanding the fixing form of the power signal box 100. The user can select any two extensions 13 according to actual needs to install the power signal box 100 on the external frame.

[0040] It should be noted that the mounting hole 131 on the extension 13 can be closed or notched, depending on the actual needs. As long as the power signal box 100 can be fixed to the external frame by using fasteners through the mounting hole 131.

[0041] In some embodiments, the box body 1 can be a metal box body 1, such as an aluminum box body or an aluminum alloy box body. A heat dissipation rib 14 is provided on one side of the box body 1. For example, the heat dissipation rib 14 is provided on the side of the box cover 11 facing away from the bottom plate 121; or, the heat dissipation rib 14 is provided on the side of the bottom plate 121 facing away from the box cover 11; or, both the box cover 11 and the bottom plate 121 are provided with heat dissipation ribs 14, which can be specifically configured according to actual needs.

[0042] See Figure 4 The heat dissipation fins 14 can protrude from the surface of the base plate 121 opposite to the cover 11. Multiple heat dissipation fins 14 are provided, spaced apart along the width of the base plate 121. When the power signal box 100 is in use, the internal electronic components, such as the main control board 2, spontaneously dissipate heat to the outside. Therefore, the heat dissipation fins 14 allow heat to be transferred to the outside through the base plate 121 and along the fins. Furthermore, the multiple heat dissipation fins 14 effectively increase the heat conduction area, helping heat to be transferred more quickly from the inside of the box 1 to the outside, thereby improving the overall heat dissipation efficiency of the power signal box 100, reducing the operating temperature of the electronic components inside the box 1, and improving reliability and service life.

[0043] See Figure 3 Multiple heat dissipation fins 14 can also be provided on the surface of the box body 1 facing away from the base plate 121. The heat dissipation fins 14 on both sides of the box body 1 work together to further improve the heat dissipation efficiency of the power signal box 100 and improve the safety of the power signal box 100.

[0044] In some embodiments, the main control board 2 can be attached to the inner surface of the housing 1 on one side where the heat dissipation fins 14 are provided, so that the heat generated by the main control board 2 can be quickly conducted to the heat dissipation fins 14 through the surface attached to the main control board 2, which further helps the heat dissipation of the main control board 2. For example, the main control board 2 can be attached to the base plate 121.

[0045] In some embodiments, the main control board 2 includes a board body 21, and a converter module and a receiving module integrated on the board body 21. The receiving modules are electrically connected to each other. The receiving modules are capable of receiving signals sent by an external transmitting card, and the converter modules are capable of processing the signals from the receiving modules and converting them into timing and level parameters usable by the display module.

[0046] In some embodiments, the power signal box 100 includes a power module 3. The power module 3 can be a power supply for the main control board 2 and the display module. For example... Figure 3 As shown, the power module 3 can be set independently of the main control board 2. The power module 3 and the main control board 2 can be set adjacent to each other along the length of the housing 1. By setting the power module 3 and the main control board 2, an electrical connection between the power module 3 and the main control board 2 can be achieved.

[0047] See Figure 3 and Figure 5 The power module 3 includes a main body 31. The opposite two sides of the main body 31 can be connected to the base plate 121 and the cover 11 respectively, so as to facilitate heat dissipation when the power module 3 is working.

[0048] The power module 3 includes a terminal block 32 located on one side of the main body 31. The terminal block 32 includes a body 321 and multiple conductive sheets 322 disposed on the body 321. Each conductive sheet 322 has a through hole. The main control board 2 has multiple through holes 22 on one side. The fixing member 323 can pass through the corresponding through holes 22 and through holes to connect the main control board 2 and the terminal block 32. By tightening the fixing member 323, the main control board 2 can be made to fit against the conductive sheets 322, thereby realizing the electrical connection between the main control board 2 and the power module 3 and realizing the transmission of current and voltage.

[0049] In some embodiments, the terminal block 32 includes insulating sheets 324. Multiple insulating sheets 324 are provided and spaced apart. A conductive sheet 322 is provided between each pair of adjacent insulating sheets 324. The insulating sheets 324 serve an insulating function, preventing adjacent conductive sheets 322 from interfering with each other. Correspondingly, the main control board 2 has multiple spaced grooves 23. An insulating sheet 324 can be snapped into a groove 23.

[0050] Understandably, the isolation plate 324 and the groove 23 work together to provide positioning, allowing the main control board 2 to be accurately and quickly installed on the power module 3.

[0051] See Figure 3 and Figure 4 The power signal box 100 also includes a power socket 4. The power socket 4 is electrically connected to the power module 3. The power socket 4 is provided with an AC port (AC Power Interface). The box body 1 has an opening 15. The AC port is correspondingly provided with the opening 15 so that external wires can pass through the opening 15 and be inserted into the AC port to input external power to the power module 3. The power module 3 can process the input power to convert it into stable power suitable for the main control board 2 and the display module.

[0052] See Figure 6 In some other embodiments of this application, the power module can be integrated together with the adapter module and the receiving module on the board. In this case, the power socket 4 can be directly mounted on the board 21 of the main control board 2. It is understood that the configuration of integrating the adapter module, the receiving module and the power module on the main control board 2, compared to the independent configuration of the power module 3 relative to the main control board 2, occupies less space and is conducive to the thin and light design of the power signal box 100.

[0053] See Figure 3and Figure 5 In some embodiments, the power signal box 100 includes a signal receiving socket 5. The signal receiving socket 5 is disposed on the board 21 and electrically connected to the receiving module. The signal receiving socket 5 has a first network interface 51. The box 1 has a first opening 16, and the first network interface 51 corresponds to the first opening 16, so that an external network cable can pass through the first opening 16 and be inserted into the first network interface 51 on the signal receiving socket 5, so as to transmit the signal emitted by an external signal source, such as a computer or other control host, to the receiving module.

[0054] In some embodiments, the power signal box 100 includes a transmitting signal socket 6. The transmitting signal socket 6 is disposed on the board 21 and electrically connected to the receiving module. The transmitting signal socket 6 has a second network interface 61. The box 1 has a second opening 17, and the second network interface 61 corresponds to the second opening 17, so that an external network cable can pass through the second opening 17 and be inserted into the second network interface 61 on the transmitting signal socket 6. The setting of the transmitting signal socket 6 can realize signal relay. For example, the transmitting signal socket 6 in one power signal box 100 can be connected to the receiving signal socket 5 in another power signal box 100 through a network cable, thereby realizing unified control of the two power signal boxes 100 by an external signal source.

[0055] The first opening 16 can be located on the same side of the box body 1 and connected to the second opening 17, which is beneficial for processing the box body 1 and reduces manufacturing costs.

[0056] See Figure 3 and Figure 4 In some embodiments, the power signal box 100 includes a socket 7, which is mounted on and electrically connected to the main control board 2. Specifically, the socket 7 is mounted on the board body 21 and electrically connected to the receiving module. The box body 1 has a plug hole 18 corresponding to the socket 7, so that an external data connection cable 200 can be plugged into the socket 7 through the plug hole 18. Through the data connection cable 200, the power signal box 100 can control the display module.

[0057] The socket 7 has an interface 71, which can be a USB interface, such as a Type-B interface or a Type-C interface. Preferably, the socket 7 is a reversible socket, meaning that the interface 71 is a reversible interface, such as a Type-C interface. Correspondingly, the connector on the data cable 200 is a Type-C connector adapted to the Type-C interface 71. The reversible interface 71 allows users to quickly plug the cable into the socket 7 without worrying about the orientation of the connector, facilitating a quick connection between the data cable 200 and the power signal box 100.

[0058] Multiple sockets 7 are provided, so one power signal box 100 can connect to multiple display modules via multiple data connection cables 200. When actually using the power signal box 100 of this application, the customer can select the number of display modules according to their own needs.

[0059] It is understood that the power signal box 100 in this application is independent of the display module, which facilitates maintenance. Furthermore, one power signal box 100 can connect multiple display modules simultaneously, and the main control board 2 inside the power signal box 100 integrates an adapter module and a receiving module. Compared to the situation where multiple LED display units with an integrated cabinet structure are electrically connected, where each LED display unit has its own receiver card and adapter board, the power signal box 100 in this application effectively saves the cost of setting up multiple receiver cards and multiple adapter boards.

[0060] Multiple sockets 7 can be arranged along one side of the housing 1. Correspondingly, multiple plug holes 18 are provided on the same side of the housing 1 corresponding to the sockets 7. Alternatively, multiple sockets 7 can be provided on both opposite sides of the main control board 2, and correspondingly, multiple plug holes 18 are provided on both opposite side surfaces of the housing 1. The arrangement of providing sockets 7 on both opposite sides of the main control board 2, compared to the arrangement of providing sockets 7 on only one side of the main control board 2, expands the number of sockets 7, allowing more display modules to be connected via external data connection cables 200. It also simplifies the physical wiring when multiple data connection cables 200 are connected to the power signal box 100, resulting in neater wiring.

[0061] Furthermore, since the socket 7 is electrically connected to the receiving module on the board 21, the spacing between multiple sockets 7 on the same side of the main control board 2 can be minimized to shorten the wiring between the socket 7 and the receiving module, thereby saving costs. It is understood that the box 1 also has multiple insertion holes 18 corresponding to the sockets 7. These insertion holes 18 on the same side of the box 1 can be interconnected to facilitate the processing of the box 1 and accelerate its production efficiency.

[0062] The plug hole 18 on the power signal box 100 of this application has a convex shape on the edge contours on both sides, which can cooperate with the external data connection cable 200, making the connection between the power signal box 100 and the data connection cable 200 more stable and conducive to the stable transmission of signals and power.

[0063] Specifically, see Figure 3 The socket 18 includes a main body area 181, a first hole area 182, and a second hole area 183. The interface 71 in the socket 7 corresponds to the main body area 181, so that the connector 91 in the data connection cable 200 can pass through the main body area 181 and be inserted into the interface 71.

[0064] The first hole area 182 and the second hole area 183 are located on opposite sides of the main body area 181. Both the first hole area 182 and the second hole area 183 are connected to the main body area 181. The edge contour of the first hole area 182 is convex, and the edge contour of the second hole area 183 is convex. Along the centerline of the main body area 181, the edge contours of the first hole area 182 and the second hole area 183 are arranged in a mirror-symmetrical manner.

[0065] Either the first hole area 182 or the second hole area 183 can be adapted to the snap-fit ​​structure in the data connection cable 200, so that the snap-fit ​​structure 922 is snapped and fixed to the box 1 through the first hole area 182 or the second hole area 183, thereby enhancing the connection stability between the data connection cable 200 and the power signal box 100, and preventing the data connection cable 200 from being accidentally subjected to external force, which would cause the connection between the data connection cable 200 and the power signal box 100 to become loose and result in the interruption of signal transmission.

[0066] See also Figure 3 The edge contour of the first hole area 182 is set in a convex shape, so that the edge contour of the part between two adjacent first hole areas 182 is also convex.

[0067] Please see Figure 7 and Figure 8 The present invention also provides a signal device 1000, including the aforementioned power signal box 100 and data connection cable 200.

[0068] The data connection cable 200 includes a cable body 8 and a connector 91 located at the end of the cable body 8. The connector 91 includes a connector 91 (not shown) and a snap-fit ​​structure 922. The connector 91 can pass through the plug hole 18 on the signal connector and be adapted to be plugged into the socket 7, thereby forming an electrical connection between the data connection cable 200 and the power signal box 100.

[0069] It is understood that connector 91 is compatible with interface 71 of socket 7 on power signal box 100. Preferably, connector 91 is a reversible connector, such as a Type-C connector, so that the user can quickly connect to power signal box 100 regardless of the orientation of connector 91.

[0070] The snap-fit ​​structure 922 can be snapped and fixed to the power signal box 100 through the plug hole 18.

[0071] Specifically, the connector 91 includes a connector body 93, a snap-fit ​​structure 922, and the connector 91, both of which are disposed on the connector body 93. The snap-fit ​​structure 922 includes an elastic portion 921 and a pressing portion 922. The elastic portion 921 is disposed on the connector body 93 and extends beyond the surface of the connector body 93. The pressing portion 922 is disposed on the end of the elastic portion 921 that extends beyond the connector body 93. The elastic portion 921 is elastic; when an external force is applied to the pressing portion 922, the elastic portion 921 can undergo elastic deformation, allowing the pressing portion 922 to approach the connector body 93 and extend into the interior of the power signal box 100 through the first hole area 182 or the second hole area 183. After the elastic portion 921 recovers its deformation, the pressing portion 922 moves away from the connector body 93 and abuts against the inner wall of the box 1, thus snapping the snap-fit ​​structure 922 onto the box 1.

[0072] See Figure 3 and Figure 8 The following description uses the snap-fit ​​structure 92 being snapped and fixed to the power signal box 100 via the first hole area 182 as an example. The first hole area 182 includes a first area 182a and a second area 182b connected to the first area 182a. The first hole area 182 is disposed on the peripheral side plate 122. The peripheral side plate 122 includes two protruding edges 122a, which are spaced apart to form the first area 182a. The pressing part 922 includes a pressing body 922a and an extension 922b. An elastic part 921 and an extension 922b are respectively connected to opposite sides of the pressing body 922a.

[0073] While the connector 91 is inserted into the socket 7, the crimping body 922a passes through the second region 182b, and the side wall of the protrusion 122a is pressed against the crimping body 922a, causing the elastic part 921 connected to the crimping body 922a to deform, and the crimping body 922a moves closer to the connector 91; until the crimping body 922a is completely housed inside the housing 1, the crimping body 922a disengages from the abutment between itself and the protrusion 122a, and moves away from the connector 92 under the action of the elastic part 921. At this time, the protrusion 122a is close to the inner side wall of the main control plate 2 inside the housing 1, preventing the crimping body 922a from disengaging from the inside of the housing 1, thereby achieving the fixation of the snap-fit ​​structure 922 on the housing 1. At this time, the extension section 922b is housed in the first region 182a.

[0074] It is understood that the steps to disconnect the data connection cable 200 from the power signal box 100 can be as follows: the user presses the extension section 922b with their finger, causing the elastic part 921 to deform, and the crimping body 922a to approach the connector 91 until the crimping body 922a disengages from the inner wall of the protrusion 122a; then the connector 9 is moved to the outside of the power signal box 100, so that the crimping body 922a passes through the second area 182b and moves to the outside of the box 1.

[0075] The power signal box 100 of this application is set independently of the display module, and does not need to be integrated with the display module in the same cabinet, thus eliminating the cabinet structure, saving costs, and also facilitating later maintenance. Furthermore, the power signal box 100 has multiple sockets 7, allowing it to connect to multiple display modules via data connection cables 200. This facilitates easy disassembly and assembly, allowing customers to flexibly configure the number of display modules according to their needs. In addition, the plug-in holes 18 on the power signal box 100 cooperate with the snap-fit ​​structure in the data connection cable 200 to achieve a more stable connection between the power signal box 100 and the data connection cable 200, ensuring stable signal transmission. Moreover, the structural design of the power signal box 100 effectively guarantees its safety.

[0076] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
