Description

Technical Field

[0001] This utility model relates to the field of circuit board reinforcement technology, and in particular to a flexible circuit board reinforcement structure. Background Technology

[0002] Flexible circuits (FPCs) are printed circuits made with polyester film or polyimide as the substrate, offering high reliability and excellent flexibility. By embedding circuit designs into thin, flexible plastic sheets, a large number of precision components can be packed into narrow and limited spaces, forming a flexible circuit. This type of circuit can be bent and folded at will, is lightweight, small in size, has good heat dissipation, and is easy to install, breaking through the limitations of traditional interconnection technologies. The components of a flexible circuit include insulating film, conductors, and adhesives. Common FPCs typically rely solely on a protective film covering the circuit board to improve protection.

[0003] For example, the prior art Chinese patent publication number "CN221995697U" provides a flexible circuit board reinforcement structure, including a reinforcement base frame assembly and a reinforcement top frame assembly. A flexible circuit board is softly pressed between the reinforcement base frame assembly and the reinforcement top frame assembly, and a number of fixing screws are provided on the side of the reinforcement base frame assembly and the reinforcement top frame assembly for pressing and fixing.

[0004] This device features a reinforced base frame and a reinforced top frame assembly that are quickly installed and reinforced on both the top and bottom sides of the flexible circuit board. This design gives the flexible circuit board strong anti-compression performance. The base frame and top frame provide rigid anti-compression protection for the outer layer of the flexible circuit board on both the top and bottom sides, while the soft bottom pad and soft top pad provide soft buffer protection for the inner layer of the flexible circuit board on both the top and bottom sides. This design ensures that the flexible circuit board is not easily damaged by compression, even when subjected to compressive force, as the outer layer is hard and the inner layer is soft. This makes the flexible circuit board less susceptible to damage from compression and highly practical.

[0005] Existing flexible circuit board reinforcement structures fail to reinforce both sides of the flexible circuit board, which is relatively soft overall. Furthermore, after reinforcing the surface of the flexible circuit board, it is not convenient to match the position and install it with external structures.

[0006] Therefore, a flexible circuit board reinforcement structure is proposed. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies where surface reinforcement of flexible circuit boards makes it difficult to match their positions and connect them with external structures. Therefore, this invention proposes a flexible circuit board reinforcement structure.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Design a flexible circuit board reinforcement structure, including a flexible circuit board, with fixing and protective mechanisms installed on the upper and lower sides of the flexible circuit board, and a connecting mechanism installed on the outside of the fixing and protective mechanisms;

[0010] The fixed protective mechanism includes:

[0011] A protective pad with a gap is provided on the outside of the flexible circuit board, and an abutment sleeve is uniformly fixed on the surface of the protective pad.

[0012] The connecting mechanism includes:

[0013] The gap is set on the connecting plates on the outer sides of both ends of the flexible circuit board. The side of the connecting plate has an adjustment groove. The upper and lower ends of the connecting plate are horizontally fixed with mounting plates. The two ends of the mounting plates have mounting holes.

[0014] Furthermore, the protective pad has a rectangular structure and is horizontally arranged, while the abutting sleeve has a circular structure and is vertically arranged. Both the protective pad and the abutting sleeve are made of thermally conductive silicone.

[0015] Furthermore, the fixed protective mechanism also includes:

[0016] A protective cover is bonded to the outside of the protective pad, and a reinforcing frame is fixed to the outer edge of the protective cover.

[0017] Furthermore, the protective cover is horizontally positioned, the reinforcing frame is a rectangular frame structure, both the reinforcing frame and the protective cover are made of rigid plastic, and the outer end of the abutment sleeve protrudes outward from the outer side of the protective cover.

[0018] Furthermore, the reinforcing frame has movable grooves at both ends, and the movable grooves are elongated strip structures.

[0019] Furthermore, the connecting mechanism also includes:

[0020] A connecting rod slides through the two moving slots, with the outer end of the connecting rod sliding through the adjusting slot.

[0021] Furthermore, a first nut is fastened to the surface of the connecting rod at a position outside the moving groove, and a second nut is fastened to the surface of the connecting rod at a position on both sides of the adjusting groove. The adjusting groove is a rectangular groove structure and is vertically arranged, while the connecting rod is a threaded rod structure and is horizontally arranged.

[0022] Furthermore, connecting sleeves are fitted at both ends of the connecting rod, and a tension spring is connected between the two vertically distributed connecting sleeves. The tension spring is vertically arranged, and the connecting sleeve is slidably installed inside the adjusting groove.

[0023] The flexible circuit board reinforcement structure proposed in this utility model has the following advantages:

[0024] 1. This utility model connects a protective cover to the outside of the protective pad, and the abutment sleeves are evenly passed through the surfaces of the protective cover and the protective pad. Therefore, the protective pad and the protective cover are installed on both sides of the flexible circuit board and are connected by the abutment sleeves. This maintains a gap on both sides of the flexible circuit board, which is conducive to ventilation and heat dissipation. It also facilitates heat conduction and heat dissipation outward through the abutment sleeves with thermally conductive silicone structure. Moreover, after the connecting rods pass through both ends of the moving groove, the upper and lower connecting rods are pulled relative to each other by the connecting sleeves and tension springs. This makes the abutment sleeves and the protective cover firmly and stably abut against the surface of the flexible circuit board, thereby strengthening and reinforcing both sides of the flexible circuit board.

[0025] 2. The present invention allows for the adjustment of the position of the connecting rods on both sides of the flexible circuit board along the movable groove, and the movable connecting plate can be adjusted at both ends of the connecting rod, thereby adjusting the position of the mounting plate. Therefore, after the flexible circuit board is reinforced, the position of the mounting plate can be adjusted to facilitate the installation of the flexible circuit board in accordance with the external structure.

[0035] The fixed protection mechanism includes: a protective pad 14 with a gap set on the outside of the flexible circuit board 1, and an abutment sleeve 5 is uniformly fixed on the surface of the protective pad 14.

[0036] The protective pad 14 has a rectangular structure and is set horizontally, while the abutment sleeve 5 has a circular structure and is set vertically. Both the protective pad 14 and the abutment sleeve 5 are made of thermally conductive silicone.

[0037] The protective pad 14 and the protective cover 4 are installed on both sides of the flexible circuit board 1 and are connected by the abutting sleeve 5 to maintain a gap on both sides of the flexible circuit board 1, which is conducive to ventilation and heat dissipation, and facilitates heat conduction and heat dissipation to the outside through the abutting sleeve 5 with thermally conductive silicone structure.

[0038] The fixed protective mechanism also includes a protective cover 4 bonded to the outside of the protective pad 14, and a reinforcing frame 2 fixed to the outer edge of the protective cover 4.

[0039] The protective cover 4 is set horizontally, and the reinforcing frame 2 is a rectangular frame structure. Both the reinforcing frame 2 and the protective cover 4 are made of hard plastic structure, and the outer end of the abutment sleeve 5 protrudes outward from the outer side of the protective cover 4.

[0040] The connecting mechanism also includes a connecting rod 3 that slides through the two moving slots 15, with the outer end of the connecting rod 3 sliding through the adjusting slot 9.

[0041] A first nut 10 is fastened to the surface of the connecting rod 3 and to the outside of the moving groove 15. A second nut 11 is fastened to the surface of the connecting rod 3 and to both sides of the adjusting groove 9. The adjusting groove 9 is a rectangular groove structure and is set vertically. The connecting rod 3 is a threaded rod structure and is set horizontally.

[0042] Connecting sleeves 12 are fitted onto both ends of the connecting rod 3. A tension spring 13 is connected between the two vertically distributed connecting sleeves 12. The tension spring 13 is vertically set, and the connecting sleeves 12 are slidably installed inside the adjusting groove 9.

[0043] After the connecting rod 3 passes through both ends of the moving groove 15, the upper and lower connecting rods 3 are pulled relative to each other by the connecting sleeve 12 and the tension spring 13, so that the abutting sleeve 5 and the protective cover 4 are firmly and stably abutted against the surface of the flexible circuit board 1, thereby strengthening and reinforcing both sides of the flexible circuit board 1.

[0044] Example 2

[0045] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shows a flexible circuit board reinforcement structure, which includes a flexible circuit board 1. Fixed protective mechanisms are installed on the upper and lower sides of the flexible circuit board 1, and a connecting mechanism is installed on the outside of the fixed protective mechanisms.

[0046] The connection mechanism includes: a connecting plate 7 with a gap set on the outer sides of both ends of the flexible circuit board 1, an adjustment groove 9 on the side of the connecting plate 7, and mounting plates 6 horizontally fixed at the upper and lower ends of the connecting plate 7, with mounting holes 8 at both ends of the mounting plates 6.

[0047] The reinforcing frame 2 has movable grooves 15 at both ends, and the movable grooves 15 are long strip structures.

[0048] The connecting mechanism also includes a connecting rod 3 that slides through the two moving slots 15, with the outer end of the connecting rod 3 sliding through the adjusting slot 9.

[0049] A first nut 10 is fastened to the surface of the connecting rod 3 and to the outside of the moving groove 15. A second nut 11 is fastened to the surface of the connecting rod 3 and to both sides of the adjusting groove 9. The adjusting groove 9 is a rectangular groove structure and is set vertically.

Therefore, after the flexible circuit board 1 is reinforced, the position of the mounting plate 6 can be adjusted to match the external structure for installation of the flexible circuit board 1.

[0051] Working method: By connecting the protective cover 4 to the outside of the protective pad 14, and evenly passing the abutment sleeve 5 through the surface of the protective cover 4 and the protective pad 14, the protective pad 14 and the protective cover 4 are installed on both sides of the flexible circuit board 1 and are connected by the abutment sleeve 5. This maintains a gap on both sides of the flexible circuit board 1, which is conducive to ventilation and heat dissipation, and also facilitates heat conduction and heat dissipation to the outside through the abutment sleeve 5 with thermally conductive silicone structure.

[0052] Moreover, after the connecting rod 3 passes through both ends of the moving groove 15, the upper and lower connecting rods 3 are pulled relative to each other by the connecting sleeve 12 and the tension spring 13, so that the abutting sleeve 5 and the protective cover 4 are firmly and stably abutted against the surface of the flexible circuit board 1, thereby strengthening and reinforcing both sides of the flexible circuit board 1.

[0053] The position of the connecting rods 3 on both sides of the flexible circuit board 1 can be adjusted along the moving groove 15, and the connecting plate 7 can be adjusted at both ends of the connecting rod 3, thereby adjusting the position of the mounting plate 6. Therefore, after the flexible circuit board 1 is reinforced, the position of the mounting plate 6 can be adjusted to match the external structure for installation of the flexible circuit board 1.
