[0002] With the development of technology, the application of electrical devices has become increasingly widespread, enabling functions such as image capture, video playback, and remote communication. To meet user needs, the battery capacity in these devices is increasing, and standby time is extending. Typically, electrical devices contain circuit boards connected to the batteries. As battery capacity increases, the space occupied by the batteries also increases, reducing the space available for the circuit boards. To save space, connectors are usually attached to the side of the circuit board to connect the battery terminals, thus attaching a flexible circuit board to the surface of the circuit board. When attaching the flexible circuit board to the surface of the circuit board, it is soldered. During the soldering process, solder overflow may occur, meaning molten solder may come into contact with the connectors, causing a short circuit between the flexible circuit board and the connectors, thus affecting the functionality of the electrical device. Utility Model Content

[0003] The purpose of this application is to provide a circuit board, battery assembly, and electrical device, at least to solve the problem that when a flexible circuit board is connected to the surface of a circuit board, the flexible circuit board is soldered onto the circuit board, and during the soldering process, solder overflow may occur, that is, molten solder may come into contact with the connector, causing a short circuit between the flexible circuit board and the connector, which affects the function of the electrical device.

[0004] In a first aspect, embodiments of this application provide a circuit board, the circuit board comprising: a circuit board body, conductive components, and connectors;

[0012] Optionally, a groove is provided on the connecting surface, the groove forming at least part of the insulating structure, the conductive element is disposed in the groove, and the conductive element is located at the bottom of the groove.

[0013] Optionally, the distance from the end of the conductive element away from the bottom of the groove to the bottom of the groove is less than the depth of the groove.

[0014] Optionally, the grooves are spaced apart from the second portion, and a second insulating element is provided between the second portion and the grooves.

[0015] Optionally, a third insulating element is provided in the groove, the third insulating element being located between the sidewall of the groove and the conductive element, the sidewall of the groove being an inner wall surface of the groove near the second part.

[0016] Secondly, embodiments of this application provide a battery assembly, the battery assembly including battery cells and a circuit board as described in any one of the first aspects above;

[0017] The battery cell has tabs that are connected to the connector.

[0018] Thirdly, embodiments of this application provide an electrical device, which includes the circuit board described in any one of the first aspects above, or the battery assembly described in the second aspect above.

[0019] In this embodiment, since the conductive element is disposed on the connection surface of the circuit board body, when it is necessary to connect the flexible circuit board to the circuit board body, the flexible circuit board and the conductive element can be connected, thereby enabling communication between the flexible circuit board and the circuit board body. Because at least some of the connectors are connected to the side of the circuit board body, and at least some of the connectors protrude from the connection surface along the thickness direction of the circuit board body, and an insulating structure is provided between the connectors and the conductive element, when the flexible circuit board is connected to the circuit board body, or when using the electrical equipment on which the circuit board is mounted, the insulating structure between the connectors and the conductive element ensures mutual insulation between them, effectively preventing conduction between the conductive element and the connector, and thus preventing conduction between the electrical network containing the conductive element and the electrical network containing the connector. In other words, in this embodiment of the application, by connecting at least some of the connectors to the side of the circuit board body and providing an insulating structure between the conductive parts on the connection surface and the connectors, it is possible to effectively prevent the connectors from contacting or conducting with the conductive parts.

[0031] like Figures 1 to 6 As shown, the circuit board includes: a circuit board body 10, a conductive component 20, and a connector 30.

[0032] The circuit board body 10 has a connecting surface 101, and a conductive element 20 is disposed on the connecting surface 101. The conductive element 20 is used to connect the flexible circuit board 60. At least a portion of the connector 30 is connected to the side surface 102 of the circuit board body 10, and at least a portion of the connector 30 protrudes from the connecting surface 101 along the thickness direction of the circuit board body 10. The side surface 102 is adjacent to the connecting surface 101. An insulating structure is provided between the connector 30 and the conductive element 20 to insulate each other. The connector 30 is used to connect the battery tabs.

[0033] In this embodiment, since the conductive element 20 is disposed on the connection surface 101 of the circuit board body 10, when it is necessary to connect the flexible circuit board 60 to the circuit board body 10, the flexible circuit board 60 and the conductive element 20 can be connected, so that the flexible circuit board 60 and the circuit board body 10 can communicate with each other. Since at least a portion of the connector 30 is connected to the side surface 102 of the circuit board body 10, and at least a portion of the connector 30 protrudes from the connection surface 101 along the thickness direction of the circuit board body 10, and an insulating structure is provided between the connector 30 and the conductive element 20, when the flexible circuit board 60 is connected to the circuit board body 10, or when using the electrical equipment on which the circuit board is mounted, the insulating structure between the connector 30 and the conductive element 20 can insulate each other, effectively preventing the conductive element 20 and the connector 30 from conducting, thereby preventing the electrical network where the conductive element 20 is located from conducting with the electrical network where the connector 30 is located. That is, in this embodiment of the application, by connecting at least a portion of the connectors 30 to the side 102 of the circuit board body 10, and providing an insulating structure between the conductive element 20 and the connectors 30 on the connection surface 101, it is possible to effectively prevent the connectors 30 and the conductive element 20 from contacting or conducting. Thus, when the flexible circuit board 60 is connected to the circuit board body 10, it is possible to effectively prevent a short circuit between the flexible circuit board 60 and the connectors 30, which would affect the function of the electrical equipment.

[0034] It should be noted that when the circuit board is used in electrical equipment, the battery terminals in the electrical equipment can be connected to the connector 30, thereby protecting the battery.

[0035] In addition, in this embodiment, the circuit board body 10 can be a printed circuit board (PCB). Furthermore, the connector 30 is conductive, so that after connecting the connector 30 to the battery terminals, the connector 30 can transmit information from the circuit board body 10 to the battery, or transmit information from the battery to the circuit board body 10.

[0036] In some embodiments, the conductive element 20 may include at least one of conductive adhesive and solder 002. Specifically, the conductive element 20 may consist only of conductive adhesive. In this case, when connecting the flexible circuit board 60 to the circuit board body 10, the flexible circuit board 60 is directly bonded to the circuit board body 10 using conductive adhesive, and the conductive adhesive is conductive, ensuring communication between the flexible circuit board 60 and the circuit board body 10. Alternatively, the conductive element 20 may consist only of solder 002. In this case, when connecting the flexible circuit board 60 to the circuit board body 10, such as... Figure 1 As shown, the flexible circuit board 60 can be soldered to the solder 002 using the solder head 001, thereby connecting the flexible circuit board 60 to the circuit board body 10 and enabling communication between the flexible circuit board 60 and the circuit board body 10. Alternatively, the conductive element 20 may also include both solder 002 and conductive element 20. In this case, it is equivalent to a portion of the conductive element 20 being solder 002 and another portion being conductive adhesive. Therefore, when connecting the flexible circuit board 60 to the conductive element 20, the flexible circuit board 60 can be connected to both the solder 002 and the conductive adhesive, thus connecting the flexible circuit board 60 to the circuit board body 10.

[0037] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the connector 30 includes a first part 31 and a second part 32 connected together; the first part 31 is connected to the side 102 of the circuit board body 10, the second part 32 is connected to the connecting surface 101, and an insulating structure is provided between the second part 32 and the conductive member 20 so that the second part 32 and the conductive member 20 are mutually insulated.

[0038] Since the first part 31 is connected to the side 102 of the circuit board body 10 and the second part 32 is connected to the connecting surface 101, the connector 30 is effectively connected to both the side 102 and the connecting surface 101 of the circuit board body 10. This results in a larger connection area between the connector 30 and the circuit board body 10, providing more stable support for the connector 30 after it is connected to the positive and negative terminals of the battery. Furthermore, an insulating structure is provided between the second part 32 and the conductive element 20, preventing them from conducting or making contact. In other words, by connecting the first part 31 to the side 102 of the circuit board body 10 and the second part 32 to the connecting surface 101, the connection area between the connector 30 and the circuit board body 10 is increased, improving the stability of the circuit board body 10's support for the connector 30.

[0039] It should be noted that the first part 31 can be soldered to the side surface 102 of the circuit board body 10, and the second part 32 can be soldered to the connecting surface 101 of the circuit board body 10, so that the first part 31 is connected to the side surface 102 of the circuit board body 10, and the second part 32 is connected to the connecting surface 101 of the circuit board body 10. Of course, the first part 31 can also be connected to the side surface 102 of the circuit board body 10 using conductive adhesive, and the second part 32 can also be connected to the connecting surface 101 of the circuit board body 10 using conductive adhesive.

[0040] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the second part 32 and the conductive element 20 are spaced apart, and the insulating structure includes a first insulating element 40; the first insulating element 40 is disposed between the second part 32 and the conductive element 20, and the first insulating element 40 is used to insulate the second part 32 and the conductive element 20.

[0041] Because the second part 32 and the conductive element 20 are spaced apart, there is a certain distance between them. Therefore, a first insulating element 40 can be provided between the second part 32 and the conductive element 20. The first insulating element 40 can prevent the conductive element 20 from contacting or conducting with the second part 32, thereby insulating the second part 32 from the conductive element 20. In other words, by providing the first insulating element 40, insulation between the second part 32 and the conductive element 20 can be easily achieved.

[0042] It should be noted that the first insulating component 40 can be insulating adhesive. Of course, the first insulating adhesive can also be other components with insulating properties, such as plastic. The specific type of the first insulating component 40 is not limited in this embodiment. The insulating adhesive can be insulating glue or insulating paper.

[0043] Furthermore, when the conductive component 20 is solder 002, by providing a first insulating component 40 between the second part 32 and the conductive component 20, even if the solder 002 melts and flows towards the second part 32 when the flexible circuit board 60 is soldered to the solder 002, the molten solder 002 will be blocked by the first insulating component 40, preventing the solder 002 from contacting the second part 32, thereby preventing the flexible circuit board 60 from conducting with the connector 30. When the conductive component 20 is conductive adhesive, by providing a first insulating component 40 between the second part 32 and the conductive component 20, even if the conductive adhesive flows towards the second part 32 when the flexible circuit board 60 is bonded to the conductive adhesive, the conductive adhesive will be blocked by the first insulating component 40, preventing the conductive adhesive from contacting the second part 32, thereby preventing the flexible circuit board 60 from conducting with the connector 30.

[0044] Furthermore, in this embodiment, the length of the first insulating member 40 in the longitudinal direction of the circuit board is L1, and the distance between the second part 32 and the conductive member 20 is L2, wherein: 0.5mm ≥ L2 - L1 ≥ 0mm. When the first insulating member 40 is insulating tape, the thickness of the insulating tape is relatively small, so 0.5mm ≥ L2 - L1 ≥ 0mm can meet the thickness requirements of the insulating tape, facilitating the placement of insulating tape between the second part 32 and the conductive member 20. When the first insulating member 40 is another insulating structure, 0.5mm ≥ L2 - L1 ≥ 0mm can meet the distance requirements of other insulating structures, facilitating the placement of other insulating structures between the second part 32 and the conductive member 20, and also making the circuit board structure more compact, avoiding the problem of increased circuit board size causing inconvenience in the placement of other components when arranging the circuit board in electrical equipment. For example, the first insulating member 40 is an insulating layer, that is, the first insulating member 40 forms an insulating layer through a nano-coating; by setting 0.5mm ≥ L2 - L1 ≥ 0mm, the requirements for setting a nano-coating can be met. The nano-coating can be directly applied to the surface of the second portion 32 facing the conductive element 20. Additionally, in embodiments of this application, such as... Figure 2 As shown, the length direction of the circuit board can be Figure 2 The X direction indicated by the middle arrow.

[0045] It should be noted that L2-L1 can be any value greater than or equal to 0 mm and less than or equal to 0.5 mm. For example, L2-L1 is 0.01 mm, 0.02 mm, 0.1 mm, or 0.5 mm. The specific value of L2-L1 is not limited in the embodiments of this application.

[0046] Additionally, in some embodiments, the first insulating member 40 is connected to the connection surface 101 between the second portion 32 and the conductive member 20; and / or, the first insulating member 40 is connected to the surface of the second portion 32 facing the conductive member 20.

[0047] When the first insulating member 40 is connected to the connection surface 101 between the second part 32 and the conductive member 20, when the flexible circuit board 60 is connected to the conductive member 20, even if the conductive member 20 flows towards the second part 32, the conductive member 20 will be blocked by the first insulating member 40 to prevent the conductive adhesive from contacting the second part 32; when the first insulating member 40 is connected to the surface of the second part 32 facing the conductive member 20, when the flexible circuit board 60 is connected to the conductive member 20, even if the conductive member 20 flows towards the second part 32, when the conductive member 20 flows to the second part 32, the conductive member 20 will be blocked by the first insulating member 40 to prevent the conductive member 20 from contacting the second part 32.

[0048] It should be noted that the first insulating member 40 may be connected only to the connection surface 101 between the second part 32 and the conductive member 20, or the first insulating member 40 may be connected only to the surface of the second part 32 facing the conductive member 20. Of course, the first insulating member 40 may also be connected to the connection surface 101 between the second part 32 and the conductive member 20, and the first insulating member 40 may also be connected only to the surface of the second part 32 facing the conductive member 20.

[0049] Additionally, in some embodiments, such as Figure 4 or Figure 5 As shown, a groove 103 may be provided on the connecting surface 101. The groove 103 forms at least a partial insulating structure. The conductive element 20 is disposed in the groove 103 and is located at the bottom of the groove 103.

[0050] Since the conductive element 20 is disposed in the groove 103, which forms at least a partial insulating structure, and the conductive element 20 is located at the bottom of the groove 103, when the flexible circuit board 60 is connected to the conductive element 20, even if the conductive element 20 melts, the melted conductive element 20 will be blocked by the groove wall of the groove 103, preventing the conductive element 20 from contacting the second part 32, thereby preventing the flexible circuit board 60 from conducting with the connector 30. In other words, by disposing the conductive element 20 in the groove 103 on the connecting surface 101, the flexible circuit board 60 and the connector 30 can be effectively prevented from conducting.

[0051] Furthermore, when the conductive component 20 is solder 002, by placing the conductive component 20 in the groove 103 and positioning it at the bottom of the groove 103, when the flexible circuit board 60 is soldered to the solder 002, even if the solder 002 melts and flows towards the second part 32, the molten solder 002 will be blocked by the groove wall of the groove 103, preventing the solder 002 from contacting the second part 32, thereby preventing the flexible circuit board 60 from conducting with the connector 30. When the conductive component 20 is conductive adhesive, by placing the conductive component 20 in the groove 103 and positioning it at the bottom of the groove 103, when the flexible circuit board 60 is bonded to the conductive adhesive, even if the conductive adhesive flows towards the second part 32, the conductive adhesive will be blocked by the groove wall of the groove 103, preventing the conductive adhesive from contacting the second part 32, thereby preventing the flexible circuit board 60 from conducting with the connector 30.

[0052] In some embodiments, the distance from the end of the conductive element 20 away from the bottom of the groove 103 to the bottom of the groove 103 is less than or equal to the depth of the groove 103. With this arrangement, even if the conductive element 20 flows, it will be blocked by the groove wall of the groove 103, further ensuring that the conductive element 20 will not come into contact with the second part 32, thereby preventing the connector 30 from coming into contact with the conductive element 20.

[0053] Furthermore, in this embodiment, the depth of the groove 103 is H, which satisfies: H≥0.08mm. The height of the conductive element 20 is typically less than or equal to 0.08mm. Therefore, by setting H≥0.08mm, it can be ensured that the height of the conductive element 20 is less than or equal to the depth of the groove 103, ensuring that the conductive element 20 is effectively blocked by the groove 103 and preventing contact between the conductive element 20 and the connector 30.

[0054] It should be noted that H can be any value greater than or equal to 0.08 mm, for example, H is 0.08 mm, H is 0.09 mm, or H is 0.1 mm. The specific value of H is not limited in the embodiments of this application.

[0055] Additionally, in some embodiments, such as Figure 5 As shown, the groove 103 and the second part 32 are spaced apart, and a second insulating member 50 is provided between the second part 32 and the groove 103.

[0056] Since a second insulating member 50 is provided between the second portion 32 and the groove 103, the second insulating member 50 can further insulate the conductive member 20 from the second portion 32. Specifically, when the flexible circuit board 60 is connected to the conductive member 20, the conductive member 20 flows. Even if the conductive member 20 overflows from the groove 103 and flows towards the second portion 32, the second insulating member 50 can effectively block the conductive member 20, preventing the conductive member 20 overflowing from the groove 103 from contacting the second portion 32, thereby effectively preventing the conductive member 20 from conducting with the connector 30, that is, effectively preventing the flexible circuit board 60 from conducting with the connector 30.

[0057] It should be noted that the second insulating component 50 can be insulating adhesive. Of course, the second insulating adhesive can also be other components with insulating properties, such as plastic. The specific type of the second insulating component 50 is not limited in this embodiment. The insulating adhesive can be insulating glue or insulating paper.

[0058] Additionally, in this embodiment, the second insulating member 50 is connected to the connection surface 101 between the second portion 32 and the conductive member 20; and / or, the second insulating member 50 is connected to the surface of the second portion 32 facing the groove 103.

[0059] In addition, in this embodiment, a third insulating member 51 is provided in the groove 103. The third insulating member 51 is located between the side wall of the groove 103 and the conductive member 20. The side wall of the groove 103 is an inner wall surface of the groove 103 near the second part 32.

[0060] Because a third insulating member 51 is provided in the groove 103, and the third insulating member 51 is located between the second part 32 and the conductive member 20, the third insulating member 51 can further insulate the conductive member 20 from the second part 32. Specifically, when the flexible circuit board 60 is connected to the conductive member 20, the conductive member 20 flows. Even if the conductive member 20 melts, when the molten conductive member 20 flows in the groove 103, the molten conductive member 20 is blocked by the third insulating member 51, effectively preventing the conductive member 20 from conducting with the connector 30, that is, effectively preventing the flexible circuit board 60 from conducting with the connector 30.

[0061] In addition, in this embodiment, a third insulating member 51 can be provided in the groove 103, and a second insulating member 50 can be provided between the second part 32 and the groove 103. In this case, the second insulating member 50 and the third insulating member 51 can simultaneously block the conductive member 20 and the second part 32 of the connector 30, further preventing the conductive member 20 from contacting the second part 32. The third insulating member 51 can be connected to the second insulating member 50. Furthermore, the third insulating member 51 can be provided on the groove wall of the groove 103 near the second part 32, and is located between the second part 32 and the conductive member 20.

[0062] In addition, in this embodiment, the third insulating member 51 can be attached to the side wall of the groove 103. Of course, the third insulating member 51 can also be spaced apart from the side wall of the groove 103, and the third insulating member 51 is located between the side wall of the groove 103 and the conductive member 20.

[0063] Additionally, in some embodiments, such as Figure 1 As shown, the circuit board may also include a flexible circuit board 60, which is connected to the conductive element 20. By providing the flexible circuit board 60, electronic components can be mounted on it, which helps the circuit board to achieve more functions and provides better protection for the battery.

[0064] In this embodiment, since the conductive element 20 is disposed on the connection surface 101 of the circuit board body 10, when it is necessary to connect the flexible circuit board 60 to the circuit board body 10, the flexible circuit board 60 and the conductive element 20 can be connected, so that the flexible circuit board 60 and the circuit board body 10 can communicate with each other. Since at least a portion of the connector 30 is connected to the side surface 102 of the circuit board body 10, and at least a portion of the connector 30 protrudes from the connection surface 101 along the thickness direction of the circuit board body 10, and an insulating structure is provided between the connector 30 and the conductive element 20, when the flexible circuit board 60 is connected to the circuit board body 10, or when using the electrical equipment on which the circuit board is mounted, the insulating structure between the connector 30 and the conductive element 20 can insulate each other, effectively preventing the conductive element 20 and the connector 30 from conducting, thereby preventing the electrical network where the conductive element 20 is located from conducting with the electrical network where the connector 30 is located. That is, in this embodiment of the application, by connecting at least a portion of the connectors 30 to the side 102 of the circuit board body 10, and providing an insulating structure between the conductive element 20 and the connectors 30 on the connection surface 101, it is possible to effectively prevent the connectors 30 and the conductive element 20 from contacting or conducting. Thus, when the flexible circuit board 60 is connected to the circuit board body 10, it is possible to effectively prevent a short circuit between the flexible circuit board 60 and the connectors 30, which would affect the function of the electrical equipment.

[0065] This application provides a battery assembly, which includes a battery cell and a circuit board as described in any of the above embodiments; the battery cell has tabs connected to a connector 30.
