FPCs offer advantages such as flexibility, space and weight savings, high integration, and high security and reliability, and are widely used in various electronic devices.

[0003] In flexible circuit board structures, connectors are placed at both ends of the circuit board to connect it to the corresponding circuit. Some flexible circuit boards have plugs at the ends for insertion. However, in flexible circuit boards with plugs, the plugs rely solely on their own snap-fit ​​mechanism with the structure to be inserted after connection. Without auxiliary support, uneven stress can easily occur, causing the plugs to loosen and affecting the normal use of the flexible circuit board. Utility Model Content

[0017] 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.

[0018] like Figures 1-4 As shown, a flexible circuit board with a connector includes a circuit board body 1. One end of the circuit board body 1 has a connecting plate 2, and a connector plate 3 is fixedly connected to the connecting plate 2. The other end of the circuit board body 1 has a connector 4, which is fixedly connected to the circuit board body 1. A support and clamping structure 5 is fixedly provided on the connector 4. Contact pieces 6 are fixedly installed on the connector plate 3, and the contact pieces 6 are symmetrically installed on the connector plate 3. A contact rod 7 is installed inside the connector 4, and the support and clamping structures 5 are symmetrically arranged on the connector 4.

[0019] Before installing and connecting the flexible circuit board, a supporting and clamping structure 5 is installed on the connector 4. The supporting and clamping structures 5 are symmetrically arranged on the connector 4, and then the flexible circuit board is installed and connected. During the connection process, the connecting plate 2 is pinched, and the connector plate 3 on the connecting plate 2 is connected to the corresponding interface. The contact piece 6 on the connector plate 3 is connected to the contact part in the interface. The connector 4 at the other end of the circuit board body 1 is connected to the corresponding connector, ensuring that the contact plug 7 is connected to the contact hole in the connector, thereby connecting the entire flexible circuit board to the circuit system. During the installation of the connector 4, the supporting and clamping structure 5 is elastically adjusted to avoid affecting the normal connection of the connector 4. After the connector 4 is installed, the supporting and clamping structure 5 can also play an auxiliary support role to ensure the stability of the connector 4, prevent the connector 4 from becoming loose and affecting the contact effect, and ensure the normal use of the flexible circuit board.

[0020] According to the above implementation scheme, the supporting and clamping structure 5 includes a fixed seat 501, a mounting base plate 502, an elastic component 503, and a flexible abutment piece 504. The fixed seat 501 is fixedly connected to the mounting base plate 502, and the mounting base plate 502 is installed on the plug connector 4 by bolts. The fixed seat 501 is provided with a snap-fit ​​groove. The elastic component 503 is fixedly connected to the flexible abutment piece 504, and the elastic component 503 is installed on the fixed seat 501 through the snap-fit ​​groove.

[0021] The elastic component 503 includes a rubber block 5031, a plug post 5032, a cavity 5033, a mounting groove 5034, a fixing connecting piece 5035, an elastic support piece 5036, and a square insert 5037. The rubber block 5031 is fixedly connected to the plug post 5032, and the plug post 5032 is inserted into the snap-fit ​​groove on the fixing seat 501. The cavity 5033 is formed on the rubber block 5031, and the mounting groove 5034 is formed in the cavity 5033 on the rubber block 5031. The fixing connecting piece 5035 is fixedly connected to the elastic support piece 5036. The square insert 5037 is mounted on the fixing connecting piece 5035, and the square insert 5037 is snap-fitted into the mounting groove 5034 on the rubber block 5031.

[0022] During the assembly of the support and clamping structure 5, in the elastic component 503, the fixed connecting piece 5035 and the elastic support piece 5036 are installed into the cavity 5033 on the rubber block 5031 using the square insert 5037. The square insert 5037 is then snapped into the mounting groove 5034. The flexible abutment piece 504 is fixedly installed on the rubber block 5031, and then the elastic component 503 is installed. When installing the elastic component 503, the insert post 5032 on the rubber block 5031 is connected to the snap-fit ​​groove on the fixing seat 501, so that the rubber block 5031 contacts the fixing seat 501, thereby completing the assembly of the entire support and clamping structure 5. When installing the support and clamping structure 5, the mounting base plate 502 is attached to the insert 4, and the mounting base plate 502 is fixed using screws, thereby completing the installation of the entire support and clamping structure 5. During the installation of connector 4, as connector 4 is installed and connected, the flexible abutment piece 504 on the elastic component 503 first contacts the structure of the installation part. As the insertion continues, the fixing base 501 continues to move with connector 4. After the flexible abutment piece 504 is blocked, it transmits the force to the rubber block 5031. The rubber block 5031 undergoes elastic deformation under the force. During this process, the fixing connecting piece 5035 is brought closer under the force, and the elastic support piece 5036 deforms. When the insertion is completed, under the action of the elastic support piece 5036, the fixing connecting piece 5035 exerts a force on the rubber block 5031, and the rubber block 5031 transmits the force to the flexible abutment piece 504, thereby pressing the structure of connector 4 and providing auxiliary support for connector 4. This prevents connector 4 from shaking and ensures the connection stability of connector 4.

[0023] It should be noted that by installing the support and clamping structure 5 on the connector 4, the connector 4 can abut against the corresponding structure after installation, providing auxiliary support for the connector 4, improving the connection stability of the connector 4, and preventing the connector 4 from becoming loose and causing poor contact. The elastic component 503 can deform elastically, allowing it to make way when the connector 4 is connected without affecting the normal connection of the connector 4, while ensuring the auxiliary support effect. The elastic support piece 5036, the fixed connecting piece 5035, and the square plug 5037 are set together and used in conjunction with the mounting groove 5034, which facilitates the disassembly and replacement of this part of the structure, making the operation highly convenient. The entire elastic component 503 is inserted into the fixed base 501, which can be quickly disassembled and replaced, improving the flexibility of use.

[0024] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
