[0036] For details, please refer to Figures 1 to 5 The embodiment of the present application provides a circuit board connection structure, including a circuit board 10 and an adapter board 20. The circuit board 10 is configured with a first connection portion 110, and the adapter board 20 is configured with a second connection portion 210. Among them, one of the first connection portion 110 and the second connection portion 210 is a plug, and the other is a socket. The plug is inserted into the socket of the socket to electrically connect the circuit board 10 and the adapter board 20.

[0037] In this embodiment, by constructing the first connection part 110 on the circuit board 10 and the second connection part 210 on the adapter board 20, one of the first connection part 110 and the second connection part 210 is a plug and the other is a socket, based on the plug-in connection between the plug and the socket, the circuit board 10 can be plug-in connected to the adapter board 20 and achieve electrical connection. As a result, the use of wires is reduced, the layout of the circuit board 10 is optimized, and the installation cost of the circuit board 10 is saved.

[0038] The circuit board connection structure is particularly suitable for use in televisions, and the circuit board 10 corresponds to a light board. Figures 1 to 3 As shown, LEDs can be installed on the circuit board 10. The LEDs can be designed as one row or multiple rows at intervals according to needs. Each row can be provided with one LED or multiple LEDs can be provided at intervals. The circuit board 10 and the adapter board 20 are both installed inside the back panel 30 of the TV, and the central control unit is configured outside the back panel 30 of the TV. At this time, the electrical connection between the internal circuit board 10 and the external central control unit can be achieved through a connecting wire based on the adapter board 20. In this way, the use of wires can be reduced, and the design cost and production cost can be reduced.

[0039] The circuit board 10 can be configured in a rectangular, square, long strip, comb, harpoon, or other shapes, as long as the circuit board 10 can be connected to the adapter board 20 through the cooperation between the first connection portion 110 and the second connection portion 210 .

[0040] The plug may be configured as a pad, with copper exposed on the outer surface, so that the plug can be electrically connected to the socket after being inserted into the socket of the socket. The socket may include a base, a terminal and a soldering piece, and the terminal and the soldering piece are fixed to the adapter board 20 by a tinning process.

[0041] For example, Figure 1 As shown, the first connection part 110 is a plug, and the second connection part 210 is a socket. That is, a plug is constructed on the circuit board 10, and a socket is constructed on the adapter board 20, and the electrical connection between the circuit board 10 and the adapter board 20 is achieved based on the plugging of the plug and the socket. In this embodiment, the plug is integrally formed on the circuit board 10. Since the plug is integrally formed on the circuit board 10, it is not necessary to construct other connection structures on the circuit board 10. Since the process of integrally forming the exposed copper material as a plug on each circuit board 10 during the molding stage is relatively simple, compared with the form of providing a socket on the circuit board 10, the integrally formed plug structure can further reduce costs and simplify the production process.

[0042] For example, the first connection part 110 is a socket, and the second connection part 210 is a plug. That is, a socket is constructed on the circuit board 10, and a plug is constructed on the adapter board 20, and the circuit board 10 and the adapter board 20 are electrically connected based on the plug-in connection between the plug and the socket.

[0043] In some embodiments, the socket is configured with a locking member, which is configured to connect the plug so that the plug is locked to the socket. It is understandable that the locking member is used to lock the plug so that the plug can be reliably fixed to the socket to prevent the circuit board 10 and the adapter board 20 from being disconnected.

[0044] For example, the locking member may be a plastic buckle, through which the plug is snapped into the socket of the socket, thereby achieving reliable fixation of the plug and the differential, and preventing the circuit board 10 and the adapter board 20 from being disconnected.

[0045] For example, the locking member may be a solder layer. After the plug is inserted into the socket of the socket, the plug and the socket are further fixed by tinning and soldering to achieve a reliable connection between the two and prevent the circuit board 10 and the adapter board 20 from being separated.

[0046] For example, the locking member may be an elastic pressing piece arranged in the socket. After the plug is inserted into the socket of the socket, the elastic pressing piece may press the plug so that the plug can be reliably fixed to the socket to prevent the circuit board 10 and the adapter board 20 from being disconnected.

[0047] For example, the locking member can be a fastener such as a screw. In this case, threaded holes need to be set in both the socket and the plug. The fasteners are passed through the threaded holes of the socket and the threaded holes of the plug so that the plug can be reliably fixed to the socket to prevent the circuit board 10 and the adapter board 20 from being connected and separated.

[0048] like Figure 2 As shown, in some embodiments, at least two first connection parts 110 are configured on the circuit board 10. Based on the reasonable layout of the spacing between the first connection parts 110, the circuit board 10 can have a suitable size and facilitate the plugging of the circuit board 10 and the adapter board 20.

[0049] The number of the first connection parts 110 matches the number of the second connection parts 210 , and the number of the first connection parts 110 and the second connection parts 210 may be selected based on the number and distribution of LEDs on the circuit board 10 .

[0050] like Figure 1 As shown, in some embodiments, each circuit board 10 may be provided with only one first connection portion 110, and a plurality of circuit boards 10 may be provided. At the same time, a corresponding number of second connection portions 210 are provided on the adapter board 20 based on the number of circuit boards 10. For example, when there are three circuit boards 10, three second connection portions 210 are provided on the adapter board 20 accordingly.

[0051] In some embodiments, the plug is constructed with at least two conductive parts spaced apart from each other, the conductive parts extending toward the socket, wherein the spacing between each two adjacent conductive parts is 1 mm to 2 mm.

[0052] It is understandable that the conductive part is a connection pin or a gold finger constructed on the plug, which is used to make the plug and the socket electrically connected after being plugged in. The spacing between two adjacent conductive parts is set to 1 mm to 2 mm, which can ensure the reliability of the signal connection between the plug and the socket, as well as the reliability of the short circuit test and the electrostatic test. For example, the spacing between two adjacent conductive parts can be 1 mm, 2 mm, or any value therebetween.

[0053] The plug further includes an insulating portion between each two adjacent conductive portions, the insulating portion being used to insulate the two adjacent conductive portions to prevent short circuits, and the width of the insulating portion corresponding to the spacing between the two adjacent conductive portions.

[0054] In some embodiments, a protective layer is provided on the outer surface of the conductive part to protect the conductive part. Specifically, the protective layer can be constructed on the outer surface of the conductive part by electroplating. For example, the protective layer can be a tin-plated layer or a gold-plated layer, which can prevent oxidation or water absorption salt spray from causing rust and other undesirable phenomena. Alternatively, the protective layer can also be constructed on the outer surface of the conductive part by coating, spraying, etc., to ensure that the protective layer can play a protective effect.

[0055] Based on the tin-plated layer or the gold-plated layer being the protective layer, in order to prevent the insulating part from being electrically conductive, it is not necessary to construct a protective layer on the outer surface of the insulating part.

[0056] In some embodiments, the circuit board connection structure also includes a backplane 30, which is configured with a first connection hole. The second connection part 210 is a socket, which is configured with a second connection hole. Fasteners are inserted into the first connection hole and the second connection hole for connecting the backplane 30 and the socket.

[0057] It can be understood that, based on the alignment of the first connection hole and the second connection hole, the socket can be accurately fixed on the back plate 30, so that the adapter plate 20 can be accurately installed on the back plate 30. In addition, based on the fasteners passing through the first connection hole and the second connection hole, the disassembly and assembly between the socket and the back plate 30 is very convenient. Among them, the fasteners can be screws, etc.

[0058] Since the circuit board connection structure is arranged on the back plate 30 , it can be applied to a television set to achieve installation inside the television set.

[0059] In some embodiments, the back plate 30 is constructed with a positioning mechanism, and the positioning mechanism is configured to allow the circuit board 10 to be inserted and positioned so as to be inserted with the adapter board 20 .

[0060] The positioning mechanism can play a role in positioning and sliding guide for the circuit board 10, so that the circuit board 10 can be pre-positioned by the positioning mechanism first, and then slidably installed on the adapter board 20 along the positioning mechanism. Based on the adapter board 20 being first accurately positioned and installed on the back plate 30, and then pre-positioned and guided by the positioning mechanism, the circuit board 10 and the adapter board 20 can be accurately plugged, making the installation of the circuit board 10 more convenient and quick.

[0061] The positioning mechanism may extend in the direction of the adapter plate 20, so that the circuit board 10 can gradually approach the adapter plate 20 when sliding along the positioning mechanism. For example, the positioning structure is a slide groove, the circuit board 10 is slidably installed in the slide groove, and the adapter plate 20 is located at the edge of one side of the slide groove, so that the circuit board 10 can be plugged with the adapter plate 20 after sliding along the slide groove.

[0062] For example, the positioning structure is two positioning columns arranged at intervals, and the circuit board 10 has two strip-shaped notches. The two strip-shaped notches can be respectively snapped into the two positioning columns, and the circuit board 10 can be slidably guided based on the extension direction of the strip-shaped notches. After the circuit board 10 slides along the positioning columns, it can be plugged into the adapter board 20.

[0063] For example, the positioning structure is two spaced apart limiting posts, the spacing between the two limiting posts corresponds to the width of the circuit board 10, and the two limiting posts extend in the direction of the adapter board 20. The circuit board 10 is pre-positioned and installed between the two limiting posts, and then the circuit board 10 is slid toward the adapter board 20, so that the circuit board 10 can be plugged into the adapter board 20 after sliding.

[0064] In some embodiments, the back plate 30 is configured with an adjustment mechanism 40 , and the adjustment mechanism 40 is configured to abut against the circuit board 10 , or the adjustment mechanism 40 is configured to connect the adapter plate 20 so that the circuit board 10 abuts against the back plate 30 .

[0065] It is understandable that, since a socket is constructed on the adapter board 20, the socket can only be located on the side of the adapter board 20. When the plug of the circuit board 10 is plugged into the socket, there will be a height difference between the circuit board 10 and the adapter board 20. This height difference may cause a gap to gradually appear between the circuit board 10 and the back plate 30, causing the circuit board 10 to be damaged due to stress. Based on the setting of the adjustment mechanism 40, the height difference caused by the plug-in assembly of the circuit board 10 and the adapter board 20 can be compensated, the flatness of the installation of the circuit board 10 is ensured, and the circuit board 10 is reliably installed on the back plate 30.

[0066] like Figure 4As shown, in some embodiments, the adjustment mechanism 40 can be a protrusion constructed on the back plate 30. Based on the structural setting of the protrusion, the protrusion can abut against the circuit board 10, which is used to support the circuit board 10, make up for the height difference caused by the plug-in assembly of the circuit board 10 and the adapter board 20, ensure the flatness of the installation of the circuit board 10, and prevent the circuit board 10 from being damaged. Among them, the circuit board 10 can also be bonded to the protrusion through an adhesive layer to ensure a reliable connection between the circuit board 10 and the back plate 30. Among them, the adhesive layer can be glue or the like.

[0067] like Figure 5 As shown, in some embodiments, the adjustment mechanism 40 can be a recessed portion constructed on the back plate 30. Based on the structural setting of the recessed portion, the recessed portion can accommodate the adapter plate 20, so that the circuit board 10 can directly abut against the back plate 30 to compensate for the height difference caused by the plug-in assembly of the circuit board 10 and the adapter plate 20, ensure the flatness of the installation of the circuit board 10, and prevent the circuit board 10 from being damaged. Among them, the circuit board 10 can also be bonded to the back plate 30 through an adhesive layer to ensure a reliable connection between the circuit board 10 and the back plate 30. Among them, the adhesive layer can be glue or the like.

[0068] In some embodiments, the circuit board connection structure further includes a central control unit installed on the side of the back plate 30 facing away from the circuit board 10. Figure 3 As shown, the central control unit includes a driving board 50, a power board 60 and a main control board 70. The power board 60 is electrically connected to the driving board 50. The main control board 70 is electrically connected to the driving board 50. Among them, the back plate 30 is configured with a through hole, and a connecting wire is passed through the through hole. The connecting wire is configured to connect the adapter board 20 and the driving board 50, so that the adapter board 20 is electrically connected to the central control unit.

[0069] The driving board 50 is electrically connected to the power board 60 and the main control board 70 to obtain power input and signal communication. The main control board 70 is connected to the adapter board 20 through a connecting line, thereby providing power and signals to the circuit board 10. The through holes on the back plate 30 are provided with connecting lines so that the circuit board 10 and the adapter board 20 located on the inner side of the back plate 30 can be electrically connected to the central control unit located on the outer side of the back plate 30.

[0070] In the circuit board connection structure of this embodiment, the circuit board 10 is connected to the adapter board 20 based on the plug-in method, and the adapter board 20 can be electrically connected to the external central control unit with only one connecting wire. As a result, the wires between the central control unit and the circuit board 10 are simplified, the amount of wires used is reduced, and there is no need to consider wiring and routing methods, thereby reducing design costs and production costs.

[0071] The present application also provides an electrical appliance, including the circuit board connection structure in the above embodiment. The electrical appliance particularly includes display appliances such as televisions, and of course also includes other household appliances or commercial appliances with display functions.

[0072] In this embodiment, by constructing the first connection part 110 on the circuit board 10 and the second connection part 210 on the adapter board 20, one of the first connection part 110 and the second connection part 210 is a plug and the other is a socket, based on the plug-in connection between the plug and the socket, the circuit board 10 can be plug-in connected to the adapter board 20 and achieve electrical connection. As a result, the use of wires is reduced, the layout of the circuit board 10 is optimized, and the installation cost of the circuit board 10 is saved.

[0073] Based on the application of this circuit board connection structure in televisions, for television products below 1000-level partitions, the cost of each unit can be saved by 10 to 20 yuan.

[0074] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
