Description

Technical Field

[0001] This utility model relates to the field of flexible circuit boards, and in particular to a flexible circuit board with stable connection. Background Technology

[0002] Flexible printed circuit boards (FPCBs) are flexible printed circuit boards made from polyimide (PI) or polyester film (PET) as the substrate through processes such as photolithography and etching. FPCBs have advantages such as light weight, small size, and the ability to be bent and folded, and are widely used. FPCBs are typically installed using three methods: soldering, plug-in, and press-fit. Plug-in connections are the most common connection method for flexible circuit boards due to their ease of assembly and disassembly.

[0003] During installation, plug-in flexible circuit boards are soldered to the main circuit board at one end and plugged into other components at the other end. However, in existing plug-in flexible circuit boards, the plug-in terminals are connected solely by plugging, and no additional fixing structure is provided at the plug-in terminals after connection. The plug-in terminals are prone to loosening, which affects the normal connection and use of the circuit board, impacting the corresponding equipment and resulting in mediocre performance. Utility Model Content

[0004] The main objective of this invention is to provide a flexible circuit board with stable connection, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A flexible circuit board with stable connection includes a circuit board body, one end of which is provided with a welding end and the other end of which is provided with a fixing rod. A plug-in end is connected to the fixing rod, and both ends of the fixing rod are provided with stabilizing structures. An auxiliary fixing piece is provided on the circuit board body near the welding end, and the auxiliary fixing piece is provided with a round hole.

[0007] Preferably, the stabilizing structure includes a bracket, a rigid clamping component, an elastic clamping component, and a through hole. The bracket is fixedly mounted on a fixed rod, the rigid clamping component passes through the fixed rod, and the upper end of the rigid clamping component is connected to the bracket. The through hole is formed on the bracket, and the elastic clamping component is installed in the through hole on the bracket.

[0008] Preferably, the rigid clamping assembly includes a clamping plate, an adjusting rod, a first anti-slip pad, and an adjusting screw. The clamping plate is fixedly connected to the adjusting rod, and the adjusting rod passes through the fixed rod. The adjusting rod is provided with an adjusting screw hole. The first anti-slip pad is fixed to the end of the clamping plate away from the adjusting rod. The adjusting screw passes through the bracket, and the lower end of the adjusting screw is connected to the adjusting screw hole on the adjusting rod.

[0009] Preferably, the elastic clamping assembly includes a movable rod, an elastic pressure plate, a second anti-slip pad, a spring, and a limiting control block. The movable rod and the elastic pressure plate are fixedly connected, and the movable rod passes through a through hole in the bracket. The second anti-slip pad is fixed to the lower surface of the elastic pressure plate and is located directly above the first anti-slip pad. The spring is sleeved on the movable rod, and the ends of the spring abut against the bracket and the elastic pressure plate respectively. The limiting control block is fixed to the upper end of the movable rod by mounting bolts and is located above the bracket.

[0010] Compared with the prior art, this utility model has the following beneficial effects: The stable flexible circuit board, through its sturdy structure, uses rigid and elastic clamping components to assist in fixing the fixing rod and the plug-in end, which can increase the stability of the plug-in end after connection and prevent it from falling off. The rigid clamping component ensures the clamping and fixing of the base, and can be adjusted in position to adapt to different plug-in sockets. The elastic clamping component can apply elastic clamping force to avoid damage to the plug-in end or plug-in socket due to excessive force, thus ensuring the effectiveness of use. The limit control block is fixed to the movable rod with screws, which can be quickly disassembled to remove the entire elastic clamping component, making it easy to replace the spring. It has high flexibility and adaptability. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-4 As shown, a flexible circuit board with stable connection includes a circuit board body 1. One end of the circuit board body 1 is provided with a welding end 2, and the other end of the circuit board body 1 is provided with a fixing rod 4. A plug-in end 5 is connected to the fixing rod 4. Stable structures 6 are provided at both ends of the fixing rod 4. An auxiliary fixing piece 3 is provided on the circuit board body 1 near the welding end 2, and a round hole 7 is opened on the auxiliary fixing piece 3.

[0018] During the installation of the flexible circuit board, the soldering end 2 at one end of the circuit board body 1 is connected to the main circuit board by soldering. Screws are passed through the round hole 7 to fix the auxiliary fixing piece 3, increasing the stability of the soldering end of the circuit board body 1. Then, the plug-in end 5 on the fixing rod 4 is connected to the corresponding plug-in socket, and the stabilizing structure 6 is used for auxiliary fixation to ensure the stability of the plug-in end of the circuit board body 1, thereby improving the overall stability of the flexible circuit board. After the flexible circuit board is installed, it can be used. When it is necessary to replace the components connected to the plug-in end of the flexible circuit board, the stabilizing structure 6 is adjusted to make room, and then the plug-in end 5 is removed. The corresponding component is then replaced, and the connection is made according to the above process.

[0019] According to the above implementation scheme, the stabilizing structure 6 includes a bracket 601, a rigid clamping component 602, an elastic clamping component 603, and a through hole 604. The bracket 601 is fixedly installed on the fixed rod 4. The rigid clamping component 602 passes through the fixed rod 4, and the upper end of the rigid clamping component 602 is connected to the bracket 601. The through hole 604 is opened on the bracket 601, and the elastic clamping component 603 is installed in the through hole 604 on the bracket 601.

[0020] When using the stabilizing structure 6 to assist in fixing the flexible circuit board connector, during the insertion process, the elastic clamping component 603 at the through hole 604 is moved aside. After the connector 5 is connected to the connector, the elastic clamping component 603 is released, and the elastic clamping component 603 elastically clamps the connector. Then, the rigid clamping component 602 is adjusted so that the clamping component in the rigid clamping component 602 contacts the connector, thereby completing the auxiliary fixing of the connector.

[0021] The rigid clamping assembly 602 includes a clamping plate 6021, an adjusting rod 6022, a first anti-slip pad 6023, and an adjusting screw 6024. The clamping plate 6021 is fixedly connected to the adjusting rod 6022, and the adjusting rod 6022 passes through the fixed rod 4. The adjusting rod 6022 is provided with an adjusting screw hole. The first anti-slip pad 6023 is fixed on the end of the clamping plate 6021 away from the adjusting rod 6022. The adjusting screw 6024 passes through the bracket 601, and the lower end of the adjusting screw 6024 is connected to the adjusting screw hole on the adjusting rod 6022.

[0022] When operating the rigid clamping assembly 602, rotate the adjusting screw 6024 on the bracket 601. Under the action of the adjusting screw 6024, the adjusting rod 6022 moves on the fixed rod 4, and the clamping plate 6021 and the first anti-slip pad 6023 move together until the first anti-slip pad 6023 is in close contact with the plug seat. At this time, the rigid clamping assembly 602 applies a clamping force to the plug seat, which plays a role in rigid auxiliary fixing.

[0023] The elastic clamping assembly 603 includes a movable rod 6031, an elastic pressure plate 6032, a second anti-slip pad 6033, a spring 6034, and a limit control block 6035. The movable rod 6031 and the elastic pressure plate 6032 are fixedly connected, and the movable rod 6031 passes through the through hole 604 on the bracket 601. The second anti-slip pad 6033 is fixed on the lower surface of the elastic pressure plate 6032 and is located directly above the first anti-slip pad 6023. The spring 6034 is sleeved on the movable rod 6031, and the ends of the spring 6034 abut against the bracket 601 and the elastic pressure plate 6032 respectively. The limit control block 6035 is fixed to the upper end of the movable rod 6031 by mounting bolts and is located above the bracket 601.

[0024] During the insertion process, the limit control block 6035 first applies force to the movable rod 6031, causing the movable rod 6031 to move and move along with the elastic pressure plate 6032 and the second anti-slip pad 6033, while the spring 6034 is in a compressed state. After the insertion is completed, the limit control block 6035 is released, and under the action of the spring 6034, the second anti-slip pad 6033 on the elastic pressure plate 6032 abuts against the insertion socket. The entire elastic clamping assembly 603 applies an elastic force, playing an elastic clamping role. It works in conjunction with the rigid clamping assembly 602 to ensure the stability of the flexible circuit board after insertion.

[0025] It should be noted that the sturdy structure 6, with the rigid clamping component 602 and the elastic clamping component 603 used to assist in fixing the fixing rod 4 and the plug-in end 5, can increase the stability of the plug-in end 5 after connection and prevent it from falling off. The rigid clamping component 602 ensures the clamping and fixing of the base, and can also be adjusted in position to adapt to different plug-in sockets. The elastic clamping component 603 can apply an elastic clamping force to avoid excessive force causing damage to the plug-in end 5 or the plug-in socket, thus ensuring the effectiveness of use. The limit control block 6035 is fixed to the movable rod 6031 with screws, and can be quickly disassembled to remove the entire elastic clamping component 603, making it easy to replace the spring 6034. It has high flexibility and adaptability in use.
