Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, specifically a flexible circuit board with rivets. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as "flexible boards," are printed circuits made from flexible insulating substrates. Flexible circuits offer excellent electrical performance, meeting the design needs for smaller and higher-density installations, and also help reduce assembly steps and enhance reliability. FPCBs can be freely bent, rolled, and folded, withstanding millions of dynamic bends without damaging the conductors. They can be arranged arbitrarily according to spatial layout requirements and can move and stretch freely in three-dimensional space, thus achieving integration of component assembly and wire connection.

[0003] A relevant reference is Chinese utility model patent CN219627994U, which discloses a flexible circuit board. It includes an intermediate layer and two protective layers covering opposite sides of the intermediate layer. The intermediate layer includes a substrate layer in the middle, with through-holes. The intermediate layer also includes a first and second circuit layer respectively disposed on opposite sides of the substrate layer, a first and second cover layer respectively disposed on opposite sides of the substrate layer, and a conductive element embedded in the through-holes and connecting the first and second circuit layers as a single unit. The first circuit layer is embedded within the first cover layer, and the second circuit layer is embedded within the second cover layer. This flexible circuit board avoids risks such as dry film breakage during lamination and poor hole formation during etching.

[0004] Existing flexible circuit boards have rivet holes for fixing rivets, but they do not come with rivets, which makes operation inconvenient. Furthermore, the rivet positions on existing flexible circuit boards are not easy to adjust, making them unsuitable for use under different conditions. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of existing technologies, such as the inconvenience of adjusting the position of rivets and the inconvenience of fixing rivets, and to provide a flexible circuit board with rivets.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible circuit board with rivets, comprising:

[0008] The flexible circuit board body has four connecting slots fixedly installed on its upper and lower sides. The connecting slots are annular in shape. Two flexible clamping plates are fixedly installed on both sides of the flexible circuit board body. The flexible clamping plates are convex in shape. A threaded hole is fixedly installed on one side of the inner side of the flexible clamping plate. A flexible slot is movably connected to the outer side of the flexible clamping plate. The flexible slot is C-shaped. A baffle is fixedly installed on one side of the flexible slot. The baffle is convex in shape. A connecting block is fixedly installed on the top side of the flexible slot. An installation bolt is movably connected inside the connecting block. A flexible plate is fixedly installed on one side of the flexible slot. Two sliding grooves are fixedly installed on both sides of the inner side of the flexible plate.

[0009] In a preferred embodiment, a sliding block is movably connected inside the sliding groove. The sliding block is in the shape of an "I" and is a structure for sliding.

[0010] In a preferred embodiment, the sliding block is internally movably connected to a rivet body, which is a structure for fixing.

[0011] In a preferred embodiment, a silicone ring is fixedly installed in the middle of the rivet body. The silicone ring is annular in shape and serves as a buffer and protective structure.

[0012] In a preferred embodiment, a support ring is fixedly installed at the bottom of the silicone ring, the support ring being a support structure.

[0013] In a preferred embodiment, a support spring is fixedly installed at the bottom of the support ring, and an installation ring is fixedly installed at the bottom of the support spring. The installation ring is a structure for installation.

[0014] In a preferred embodiment, a rubber ring is fixedly mounted on the bottom of the mounting ring, the rubber ring being a structure for cushioning and protection.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This rivet-embedded flexible circuit board can fix two flexible boards by interlocking between a flexible slot and a flexible plate. The baffle on one side of the flexible slot limits the movement. By rotating the mounting bolt inside the connecting block, the mounting bolt passes through the connecting block and the flexible slot, thereby fixing the flexible plate inside the flexible slot and fixing the two flexible boards. The movement of the sliding block inside the sliding groove allows for easy adjustment of the rivet body position, improving the practicality of the rivet-embedded flexible circuit board.

[0017] 2. The flexible circuit board with rivets provides protection through the flexible materials of the silicone ring and rubber ring, preventing damage to the sliding block caused by the rivet body squeezing it during fixing. The contraction of the support spring provides a buffering effect, preventing the flexible circuit board from slipping due to insecure fixing of the rivet body after fixing. This improves the practicality and stability of the flexible circuit board with rivets. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Combined with appendix Figure 1-4 In this embodiment, a flexible circuit board with rivets includes: a flexible circuit board body 1, four connecting grooves 11 fixedly installed on the upper and lower sides of the flexible circuit board body 1, the connecting grooves 11 being annular in shape, two flexible clamping plates 12 fixedly installed on both sides of the flexible circuit board body 1, the flexible clamping plates 12 being convex in shape, and a threaded hole 13 fixedly installed on one side of the interior of the flexible clamping plate 12.

[0025] Specifically, the connection grooves 11 on both sides of the flexible circuit board body 1 can be fixed with bolts, thereby fixing the flexible circuit board body 1. The flexible clamping plate 12 can be fitted with the flexible clamping groove 2, and the threaded hole 13 can be fitted and connected with the mounting bolt 23.

[0026] The outer side of the flexible clamping plate 12 is movably connected with the flexible clamping groove 2. The flexible clamping groove 2 is in a "C" shape. One side inside the flexible clamping groove 2 is fixedly installed with a baffle 21, and the baffle 21 is in a "convex" shape. One side at the top of the flexible clamping groove 2 is fixedly installed with a connecting block 22. The inside of the connecting block 22 is movably connected with a mounting bolt 23. One side of the flexible clamping groove 2 is fixedly installed with a flexible plate 24. Both sides inside the flexible plate 24 are fixedly installed with two sliding grooves 25.

[0027] Specifically, the flexible plate 24 can be fixed through the flexible clamping groove 2, and the sliding block 3 can be fixed through the sliding groove 25, enabling the sliding block 3 to slide back and forth inside it. By rotating the mounting bolt 23 inside the connecting block 22, the flexible clamping plate 12 can be fixed.

[0028] The inside of the sliding groove 25 is movably connected with a sliding block 3. The sliding block 3 is in a "work" shape. The inside of the sliding block 3 is movably connected with a rivet body 31. A silicone ring 32 is fixedly installed in the middle of the rivet body 31. The silicone ring 32 is in a circular shape. The bottom of the silicone ring 32 is fixedly installed with a support ring 33. The bottom of the support ring 33 is fixedly installed with a support spring 34. The bottom of the support spring 34 is fixedly installed with a mounting ring 35. The bottom of the mounting ring 35 is fixedly installed with a rubber ring 36.

[0029] Specifically, the rivet body 31 is limited by the sliding block 3. The silicone ring 32 and the rubber ring 36 can achieve the effect of buffering and protection, and the support spring 34 can achieve the effect of support, improving the practicability of the flexible circuit board with rivets.

[0030] Working principle: First, the flexible circuit board with rivets is placed in the designated position. Bolts can be fixed through the connecting grooves 11 on both sides of the flexible circuit board body 1, thus fixing the flexible circuit board body 1. Alternatively, the flexible plate 24 can be fixed by the engagement between the flexible clamping plate 12 and the flexible clamping groove 2. The flexible clamping plate 12 is limited by the baffle 21 inside the flexible clamping groove 2. By rotating the mounting bolt 23 inside the connecting block 22, the mounting bolt 23 can pass through the connecting block 22 and the flexible clamping groove 2, thus engaging with the threaded hole 13 inside the flexible clamping plate 12, thereby fixing the flexible clamping plate 12. This fixes both flexible plates 24, improving the efficiency of the flexible circuit board. The rivet-equipped flexible circuit board is practical and convenient for fixing two flexible boards 24. The sliding block 3 slides inside the sliding groove 25 of the flexible board 24, thereby adjusting the position of the rivet body 31. This allows for positional adjustment and installation of the rivet body 31 under different conditions. The flexible material of the silicone ring 32 at the top of the support ring 33 and the rubber ring 36 at the bottom of the mounting ring 35 provides a buffering and protective effect, preventing damage to the sliding block 3 when the rivet body 31 is fixed. The support spring 34 between the support ring 33 and the mounting ring 35 provides a buffering and supporting effect. Therefore, when the rivet body 31 is fixed, the problem of the flexible circuit board body 1 shaking up and down is avoided, improving the stability and practicality of the rivet-equipped flexible circuit board.
