Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, and in particular to a bending resistance enhancement device for flexible circuit boards. Background Technology

[0002] Flexible circuit boards (PCBs), due to their bendability, small size, and light weight, are widely used in electronic devices such as mobile phones, tablets, and wearable devices. However, in actual use, frequent bending of flexible PCBs can easily lead to problems such as circuit breakage and short circuits, seriously affecting their service life and the normal operation of electronic devices.

[0003] Currently, a common method to improve the bending resistance of flexible circuit boards is to increase the thickness of the circuit board. However, this increases the size and weight of the product, which does not conform to the development trend of modern electronic devices becoming thinner and lighter. Another method is to attach a protective film to the surface of the flexible circuit board, but the bending resistance of the protective film is limited and cannot fundamentally solve the problem.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: frequent bending of flexible circuit boards can easily lead to problems such as circuit breakage and short circuits, which seriously affect their service life and the normal operation of electronic devices; therefore, in order to address the above problems, an anti-bending enhancement device for flexible circuit boards is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where frequent bending of flexible circuit boards can easily lead to circuit breakage and short circuits, severely affecting their service life and the normal operation of electronic devices. Therefore, this invention proposes a bending resistance enhancement device for flexible circuit boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bending resistance enhancement device for a flexible circuit board, comprising a flexible circuit board body, a connecting plate electrically connected to one side of the flexible circuit board body, a connector electrically connected to the side of the flexible circuit board body away from the connecting plate, a reinforcing plate adhered to the lower surface of the flexible circuit board body, the reinforcing plate being tough, a metal mesh fixedly installed on one side of the reinforcing plate, and a heat-conducting plate fixedly connected to the side of the metal mesh away from the reinforcing plate.

[0007] The effects achieved by the above components are as follows: by bonding the reinforcing plate to the lower surface of the flexible circuit board, the overall bending resistance of the circuit board can be effectively enhanced, reducing the risk of circuit damage caused by bending. The metal mesh further strengthens the structure, and its good mechanical properties also help to improve the bending strength. Under the heat conduction of the heat-conducting plate, the heat generated by the flexible circuit board during operation can be quickly conducted away, ensuring that the circuit board operates stably at a suitable temperature, extending its service life, and improving the practicality of the device.

[0008] Preferably, the metal mesh is made of titanium alloy.

[0009] The effect achieved by the above-mentioned components is that by using titanium alloy material to make the metal mesh, the ductility and resilience of titanium alloy material can withstand large plastic deformation without easily breaking.

[0010] Preferably, the surface of the heat-conducting plate is provided with a plurality of heat dissipation holes, and the plurality of heat dissipation holes are evenly distributed on the surface of the heat-conducting plate.

[0011] The effect achieved by the above components is that by setting several heat dissipation holes on the heat-conducting plate, the heat generated by the flexible circuit board body can be effectively dissipated, thus improving the practicality of the device.

[0012] Preferably, a guide groove is formed on one side of the connecting plate, and a guide plate is fixedly connected to one side of the connector. One side of the guide plate is semi-circular, and the size of the guide plate is adapted to the size of the guide groove of the connecting plate.

[0013] The effect achieved by the above components is that by setting up guide plates and guide slots, it is easier for workers to connect the flexible circuit board bodies, thus improving the practicality of the device.

[0014] Preferably, a sealing gasket is fixedly connected to the surface of the connector, and the sealing gasket is made of silicone.

[0015] The effect achieved by the above components is that by setting a sealing gasket, a sealing effect is achieved when the flexible circuit board body is connected, thereby improving the practicality of the device.

[0016] Preferably, connecting rods are fixedly connected to both sides of the connecting plate, an elliptical plate is fixedly connected to one end of the connecting rod, a threaded rod is threaded into the elliptical plate, and an abutment plate is fixedly connected to one end of the threaded rod.

[0017] The effect achieved by the above components is to fix the flexible circuit board bodies after they are connected, thus preventing the flexible circuit board bodies from detaching under external forces and affecting the stability of the connection of the flexible circuit board bodies.

[0018] In this invention, by bonding the reinforcing plate to the lower surface of the flexible circuit board body, the overall bending resistance of the circuit board can be effectively enhanced, reducing the risk of circuit damage caused by bending. The metal mesh further strengthens the structure, and its good mechanical properties also help to improve the bending strength. Under the heat conduction of the heat-conducting plate, the heat generated by the flexible circuit board body during operation can be quickly conducted away, ensuring that the circuit board operates stably at a suitable temperature, extending its service life, and improving the practicality of the device.

[0024] Reference Figure 1-4As shown, this utility model provides a technical solution: a bending resistance enhancement device for a flexible circuit board, comprising a flexible circuit board body 1, a connecting plate 2 electrically connected to one side of the flexible circuit board body 1, a connector 3 electrically connected to the side of the flexible circuit board body 1 away from the connecting plate 2, a reinforcing plate 4 bonded to the lower surface of the flexible circuit board body 1, the reinforcing plate 4 having toughness, a metal mesh 5 fixedly installed on one side of the reinforcing plate 4, and a heat-conducting plate 6 fixedly connected to the side of the metal mesh 5 away from the reinforcing plate 4. By bonding the reinforcing plate 4 to the lower surface of the flexible circuit board body 1, the overall bending resistance of the circuit board can be effectively enhanced. The metal mesh 5 further strengthens the structure, reducing the risk of circuit damage due to bending. Its excellent mechanical properties also contribute to improved bending resistance. Under the heat conduction of the heat-conducting plate 6, it can quickly dissipate the heat generated by the flexible circuit board body 1 during operation, ensuring stable operation of the circuit board at a suitable temperature, extending its service life, and improving the practicality of the device. The metal mesh 5 is made of titanium alloy. Using titanium alloy to make the metal mesh 5 allows it to withstand large plastic deformations without easily breaking, thanks to the ductility and resilience of titanium alloy. Several [unclear - possibly referring to a specific type of surface preparation] are formed on the surface of the heat-conducting plate 6. Several heat dissipation holes 7 are evenly distributed on the surface of the heat-conducting plate 6. By setting several heat dissipation holes 7 on the heat-conducting plate 6, the heat generated by the flexible circuit board body 1 can be effectively dissipated, improving the practicality of the device. A guide groove is opened on one side of the connecting plate 2, and a guide plate 8 is fixedly connected to one side of the connector 3. One side of the guide plate 8 is semi-circular, and the size of the guide plate 8 is adapted to the size of the guide groove of the connecting plate 2. By setting the guide plate 8 and the guide groove, it is convenient for the staff to connect the flexible circuit board bodies 1, improving the practicality of the device. The surface of the connector 3 is fixedly connected to A sealing gasket 9 is provided, which is made of silicone. By setting the sealing gasket 9, a sealing effect is achieved when the flexible circuit board body 1 is connected, which improves the practicality of the device. Both sides of the connecting plate 2 are fixedly connected to the connecting rod 10. One end of the connecting rod 10 is fixedly connected to the elliptical plate 11. A threaded rod 12 is inserted into the internal thread of the elliptical plate 11. One end of the threaded rod 12 is fixedly connected to the abutment plate 13, which achieves the effect of fixing the flexible circuit board body 1 after connection, and prevents the flexible circuit board body 1 from detaching under external force, thereby affecting the stability of the connection of the flexible circuit board body 1.

[0025] Working principle: When the operator needs to reinforce the flexible circuit board body 1, the reinforcing plate 4 is adhered to the flexible circuit board body 1, which can effectively enhance the overall bending resistance of the circuit board and reduce the risk of circuit damage caused by bending. At the same time, with the metal mesh 5, the metal mesh 5 can withstand large plastic deformation without breaking due to its extension and retraction properties. Under the heat conduction of the heat-conducting plate 6, the heat generated by the flexible circuit board body 1 during operation can be quickly conducted away, ensuring that the circuit board operates stably at a suitable temperature, extending its service life, and improving the practicality of the device. When the operator needs to connect the flexible circuit board body 1, the guide plate 8 on the connector 3 is slid into the guide groove of the connector 2 until the sealing gasket 9 is in contact with the connector 2. The threaded rod 12 is rotated in the elliptical plate 11, and the threaded rod 12 drives the abutment plate 13 to move until the abutment plate 13 abuts against the connector 3, achieving the effect of fixing the flexible circuit board body 1 after connection.
