Description

Technical Field

[0001] This utility model relates to the field of flexible circuit boards, and in particular to a tensile-resistant flexible circuit board. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as flexible circuit boards, are bendable printed circuit boards made of polyimide (PI) or polyester film (PET) as the substrate. They are key components for lightweighting and integrating electronic devices. Flexible circuits offer excellent electrical performance, meet the design requirements for smaller and higher-density installations, and also help reduce assembly steps and enhance reliability.

[0003] In existing flexible printed circuit boards (FPCBs), the connectors at both ends of the main body connect to rigid circuit boards or corresponding electronic components, providing electrical connections. However, existing FPCBs lack tensile strength structures. When subjected to tension, the internal circuitry of the main body is prone to breakage, affecting normal operation. Furthermore, existing FPCBs lack auxiliary support structures at the connectors, making them susceptible to loosening under external forces, resulting in generally poor stability.

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

The snap-fit ​​protrusion is fixed to the inner side of the U-shaped elastic frame, and the U-shaped elastic frame is clamped on the flexible metal tensile strip.

Tensile-resistant structures 4 are provided on the circuit board body 1, and the two sets of tensile-resistant structures 4 are symmetrically distributed on the circuit board body 1. Positioning holes 5 are provided on the first plug-in terminal 2 and the second plug-in terminal 3, and the ends of the tensile-resistant structures 4 are connected to the positioning holes 5.

[0020] When using a flexible circuit board, the tensile-resistant structure 4 is installed on both sides of the circuit board body 1. The two ends of the tensile-resistant structure 4 are connected to the positioning holes 5 on the first connector 2 and the second connector 3, respectively, to achieve stable installation of the tensile-resistant structure 4. When connecting the flexible circuit board, the first connector 2 and the second connector 3 are connected to their corresponding sockets. At this time, the ends of the tensile-resistant structure 4 act as auxiliary supports, improving the connection stability of the flexible circuit board. When the flexible circuit board is subjected to tensile force, the tensile-resistant structure 4 provides tensile resistance, increasing the strength of the flexible circuit board, preventing damage, and ensuring normal use of the circuit board.

[0021] According to the above implementation scheme, the tensile structure 4 includes a flexible metal tensile strip 401, an elastic clamping component 402, a mounting component 403, and a circular groove 404. The flexible metal tensile strip 401 is sleeved on the circuit board body 1, the circular groove 404 is formed on the flexible metal tensile strip 401, the elastic clamping component 402 is clamped on the flexible metal tensile strip 401 through the circular groove 404, and two sets of mounting components 403 are set at the ends of the flexible metal tensile strip 401, and the two sets of mounting components 403 are respectively connected to the first plug-in terminal 2 and the second plug-in terminal 3.

[0022] During the installation of the tensile structure 4, the flexible metal tensile strip 401 is fitted onto both sides of the circuit board body 1. The mounting assembly 403 is connected to the positioning hole 5. An elastic clamping assembly 402 is provided on the flexible metal tensile strip 401 to clamp and fix the flexible metal tensile strip 401, thereby improving the connection stability between the flexible metal tensile strip 401 and the circuit board body 1. During the use of the circuit board, the flexible metal tensile strip 401 provides effective tensile resistance, increasing the tensile performance of the circuit board body 1 and ensuring the long-term use of the circuit board. The mounting assembly 403 provides auxiliary support for the plug-in terminals, ensuring the stability of the plug-in connection.

[0023] The elastic clamping assembly 402 includes a U-shaped elastic frame 4021 and a snap-fit ​​protrusion 4022. The snap-fit ​​protrusion 4022 is fixed to the inner side of the U-shaped elastic frame 4021, and the U-shaped elastic frame 4021 is clamped on the flexible metal tensile strip 401. The snap-fit ​​protrusion 4022 is snapped into the circular groove 404 on the flexible metal tensile strip 401.

[0024] When installing the elastic clamping assembly 402, the U-shaped elastic frame 4021 is clamped onto the flexible metal tensile strap 401. The snap-fit ​​protrusion 4022 on the inner side of the U-shaped elastic frame 4021 is connected to the circular groove 404 on the flexible metal tensile strap 401 to ensure the installation stability of the U-shaped elastic frame 4021. In use, the elasticity of the U-shaped elastic frame 4021 ensures that the flexible metal tensile strap 401 is stably fitted onto the circuit board body 1, thereby ensuring the tensile resistance effect.

[0025] Mounting assembly 403 includes a U-shaped mounting bracket 4031, a snap-fit ​​groove 4032, a connecting bolt 4033, a connecting groove 4034, a support spring 4035, and a connecting strip 4036. The snap-fit ​​groove 4032 is formed on the U-shaped mounting bracket 4031, and the U-shaped mounting bracket 4031 is connected to the end of the flexible metal tensile strip 401. The connecting bolt 4033 is threadedly connected to the U-shaped mounting bracket 4031, and the end of the connecting bolt 4033 is located in the positioning hole 5. The connecting groove 4034 is formed on the U-shaped mounting bracket 4031. The support spring 4035 and the connecting strip 4036 are fixedly connected, and the connecting strip 4036 is inserted into the connecting groove 4034.

[0026] When the mounting component 403 is installed onto the plug-in terminal, the U-shaped mounting bracket 4031 is set onto the plug-in terminal via the snap-fit ​​groove 4032. The U-shaped mounting bracket 4031 is fixed in place using the connecting bolts 4033 and the positioning holes 5, thus completing the stable installation of the entire tensile structure 4. During the installation of the first plug-in terminal 2 and the second plug-in terminal 3, after the plug-in terminal is connected to the corresponding part, the support spring 4035 installed through the connecting groove 4034 and the connecting strip 4036 undergoes adaptive deformation to abut against the corresponding part, providing elastic support for the plug-in terminal. This increases the connection stability of the plug-in terminal and ensures the effectiveness of use.

[0027] It should be noted that the tensile structure 4, with the flexible metal tensile strip 401 providing tensile resistance, enhances the tensile performance of the circuit board body 1, preventing damage to the circuit board body 1 under tension and ensuring the integrity and normal use of the flexible circuit board after tension. The elastic clamping component 402 assists in fixing the flexible metal tensile strip 401, ensuring relative stability of the installation. The installation component 403 is used to install the flexible metal tensile strip 401, which is convenient and quick to install and can be quickly disassembled and replaced. The support spring 4035 is installed through the connecting groove 4034 and connecting strip 4036, which provides auxiliary support for the plug-in end, improving plug-in stability. At the same time, the support spring 4035 provides elasticity, absorbing vibration and impact, preventing the plug-in end from loosening in a vibrating environment, and ensuring the performance.
