Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a connection structure between battery electrode and circuit board. Background Technology

[0002] Remote-controlled toys and electric toys are mostly battery-powered, with a battery compartment on their casing containing battery terminals. These terminals are typically connected to a circuit board inside the casing via wires. When a battery is inserted into the compartment, it connects to the circuit board via the battery terminals, thus providing power. However, the current method of connecting the battery terminals to the circuit board via wires is cumbersome. Firstly, it requires soldering the wires to both the circuit board and the battery terminals separately, and secondly, the wires are prone to breakage during product assembly and disassembly (either in the middle or at the solder joint). Consumers often lack the necessary soldering skills, leading to product failure and impacting user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a connection structure between battery electrode and circuit board, which is convenient, reliable and does not require soldering.

[0004] To achieve the above objectives, this utility model discloses a connection structure between a battery electrode and a circuit board, which is provided with locking screws corresponding to the battery electrodes one by one. The locking screws are threadedly connected to the circuit board or to the housing on which the circuit board is mounted, and the locking screws press the battery electrodes onto the circuit board. The circuit board is provided with a contact portion that is electrically connected to the battery electrodes.

[0005] By connecting the circuit board or the housing on which the circuit board is mounted using locking screws, the battery terminals are pressed firmly onto the contact points of the circuit board, thus achieving a conductive connection between the battery terminals and the circuit board. Compared to traditional wire bonding, this method eliminates the need to solder the battery terminals to the circuit board before or during assembly; simply tightening the locking screws after both are installed suffices. This makes operation more convenient, eliminates the need for soldering equipment at the assembly station, and simplifies management. Furthermore, the connection between the battery terminals and the circuit board is less prone to damage, resulting in better reliability. Additionally, the connection between the battery terminals and the housing on which the circuit board is mounted requires virtually no additional processing steps for the circuit board, and the locking screw connection is less likely to damage the circuit board.

[0006] Preferably, the housing is provided with connecting posts corresponding to the locking screws, the locking screws are threaded to the connecting posts, and the connecting posts abut against the circuit board or battery terminals; the circuit board is provided with through holes for the locking screws to pass through. The connecting posts facilitate the connection of the locking screws, and the abutment of the connecting posts against the circuit board or battery terminals ensures a more reliable connection between the battery terminals and the circuit board when the locking screws are tightened.

[0007] Preferably, the front side of the circuit board is the circuit layer, the connecting post abuts against the back side of the circuit board, and the battery electrode is pressed against the front side of the circuit board. This arrangement facilitates the connection of the circuit board to other electrical components of the product, especially when the circuit layer of the circuit board has control elements (such as buttons).

[0008] Preferably, the contact portion is arranged around the outer periphery of the through hole. This arrangement ensures a reliable conductive connection between the battery electrode and the contact portion, guaranteeing a smooth battery power supply circuit.

[0009] Preferably, the housing has a battery compartment; the battery electrode includes a first connecting segment, a bent segment, and a second connecting segment connected in sequence. The first connecting segment extends into the battery compartment for connecting the battery, and the second connecting segment is pressed onto the circuit board by a locking screw. By setting the bent segment, the second connecting segment can better fit the circuit board, ensuring the reliability of the conductive connection node between the two. At the same time, the bent segment can also limit the position of the first connecting segment in the battery compartment.

[0010] Preferably, the second connecting segment is provided with a through hole or slot for the locking screw to pass through. The through hole or slot facilitates the connection of the locking screw.

[0011] Preferably, the opening of the slot is parallel, inclined, or perpendicular to the length direction of the second connecting segment. Parallel orientation of the opening to the length direction of the second connecting segment ensures alignment between the opening and the through hole when the bending segment is bent. Inclined or perpendicular orientation of the opening to the length direction of the second connecting segment prevents the second connecting segment from easily coming loose from the locking screw, facilitating assembly.

[0012] Preferably, the through hole is an elongated hole, and the length direction of the elongated hole is parallel to the length direction of the second connecting segment. This configuration ensures that the through hole aligns with the via hole when the bent segment is bent, and also prevents the second connecting segment from easily coming loose from the locking screw even if the locking screw is loose, thus facilitating assembly.

[0013] Preferably, the battery compartment is provided with a slot for limiting the position of the first connecting segment, and the length direction of the slot is parallel to the opening direction of the battery compartment. By limiting the position of the first connecting segment with the slot, the accurate positioning of the first connecting segment can be ensured, thereby ensuring a reliable connection with the battery. During assembly, the battery electrode segments can be aligned on the same plane. After the second connecting segment and the bent segment pass through the slot, the bent segment is then bent so that the second connecting segment can be placed against the circuit board, facilitating assembly.

[0014] Preferably, the battery electrode is further provided with protrusions or springs to facilitate connection with the battery. By providing protrusions for easy connection with the positive terminal of the battery, and by providing springs for easy connection with the negative terminal of the battery, a reliable connection between the battery and the battery electrode is ensured.

[0015] This utility model has the following beneficial effects:

[0016] This invention uses locking screws to connect the circuit board or the housing on which the circuit board is mounted, thereby pressing the battery electrodes onto the contact portion of the circuit board. This achieves a conductive connection between the battery electrodes and the circuit board. Compared to traditional wire bonding, this method eliminates the need to solder the battery electrodes to the circuit board before or during assembly. Only locking screws are required after both are installed, making operation more convenient. No welding equipment is needed at the assembly station, simplifying management. Furthermore, the connection between the battery electrodes and the circuit board is less prone to damage, resulting in better reliability. Additionally, by connecting the battery electrodes to the housing on which the circuit board is mounted, the circuit board requires virtually no additional processing steps, and the locking screw connection is less likely to damage the circuit board.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] like Figures 1-5 As shown, this embodiment discloses a connection structure between a battery electrode 10 and a circuit board 20. Two battery electrodes 10 are typically provided, connecting to the positive and negative terminals of the battery respectively. A protrusion 11 is provided on the battery electrode 10 connected to the positive terminal, and a spring 12 is provided on the battery electrode 10 connected to the negative terminal. In this embodiment, the circuit layer 21 of the circuit board 20 is the front side. Contact portions 22, corresponding one-to-one with and electrically connected to the battery electrodes 10, are provided on the front side of the circuit board 20. These contact portions 22 can be lines etched onto the circuit layer 21.

[0037] Battery electrode 10 is pressed onto circuit board 20 by locking screws 40, with each locking screw 40 corresponding to a battery electrode 10. Specifically, in this embodiment, the housing 30 on which the circuit board 20 is mounted has connecting posts 31 corresponding to each locking screw 40. These connecting posts 31 abut against the reverse side of the circuit board 20. The locking screw 40 passes through the battery electrode 10 and the circuit board 20 sequentially and is threadedly connected to the connecting post 31. The locking screw 40 can be a self-tapping screw. In this case, the connecting post 31 can be a solid, or it can have a small hole to allow the self-tapping screw to be screwed in. Alternatively, the connecting post 31 may have a threaded hole adapted to the locking screw 40. The circuit board 20 has through holes 23 for the locking screw 40 to pass through.

[0038] The battery electrode 10 includes a first connecting segment 13, a bent segment 14, and a second connecting segment 15 connected in sequence. The first connecting segment 13 is placed in the battery compartment 32 of the housing 30 for connecting the battery. The aforementioned protrusion 11 or spring 12 is provided on the first connecting segment 13. A slot 33 is provided in the battery compartment 32 to limit the first connecting segment 13, and the length direction of the slot 33 is parallel to the opening direction of the battery compartment 32. By limiting the first connecting segment 13 by the slot 33, the accurate position of the first connecting segment 13 can be ensured, thereby ensuring a reliable connection with the battery. During assembly, the battery electrode 10 can be flattened (or the bent segment 14 is bent during assembly). After the second connecting segment 15 and the bent segment 14 pass through the slot 33, the bent segment 14 is bent so that the second connecting segment 15 can be placed against the circuit board 20, making assembly convenient.

[0039] The second connecting segment 15 is pressed onto the circuit board 20 by a locking screw 40. A through hole 16 is provided on the second connecting segment 15 for the locking screw 40 to pass through. Preferably, the through hole 16 is an elongated hole, and the length direction of the elongated hole is parallel to the length direction of the second connecting segment 15. This design ensures that when the bending segment 14 is bent, the through hole 16 can be aligned with the through hole 23, and that the second connecting segment 15 will not easily come out of the locking screw 40 even if it becomes loose, facilitating assembly. Furthermore, to ensure a reliable connection between the second connecting segment 15 and the contact portion 22, the contact portion 22 is arranged around the outer periphery of the through hole 23.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that the through hole 16 on the second connecting segment 15 is replaced with an open slot 17. For example... Figure 6 As shown, in preferred embodiment, the opening of the slot 17 is parallel to the length direction of the second connecting segment 15, ensuring that the slot 17 aligns with the through hole 23 when the bending segment 14 is bent. Figure 7 As shown, as a preferred embodiment, the opening of the slot 17 is inclined or perpendicular to the length direction of the second connecting section 15. This ensures that even if the locking screw 40 is loose, the second connecting section 15 will not easily come out of the locking screw 40, which facilitates assembly.

[0042] Example 3

[0043] like Figure 8 As shown, the difference between this embodiment and embodiment one or embodiment two is that the locking screw 40 passes through the circuit board 20 and the second connecting section 15 in sequence and then connects to the connecting post 31. At this time, the contact part 22 is provided on the reverse side of the circuit board 20, and the contact part 22 passes through the circuit board 20 and communicates with the circuit layer 21.

[0044] Example 4

[0045] like Figure 9 As shown, the difference between this embodiment and embodiment three is that the front side of the circuit board 20 is set downwards, so that the contact part 22 is still set on the circuit layer 21.

[0046] Example 5

[0047] like Figure 10 As shown, the difference between this embodiment and embodiment one or embodiment two is that the connecting post 31 abuts against the front side of the circuit board 20, the contact part 22 is disposed on the back side of the circuit board 20, and the contact part 22 passes through the circuit board 20 and communicates with the circuit layer 21.

[0048] Example 6

[0049] like Figure 11 As shown, the difference between this embodiment and embodiment one, two, or five is that the connecting post 31 is not specifically set to connect with the locking screw 40, and the locking screw 40 is directly connected to the housing 30.

[0050] Example 7

[0051] like Figure 12 As shown, the difference between this embodiment and embodiment one or embodiment two is that the locking screw 40 is directly threaded to the circuit board 20. In this case, the locking screw 40 can be an automatic screw, which passes through the second connecting section 15 and is directly screwed into the contact part 22 of the circuit board 20.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
