Description

Technical Field

[0001] This utility model relates to a flexible and stretchable FPC connector, belonging to the field of flexible and stretchable FPC technology. Background Technology

[0002] Flexible FPCs are printed circuit boards made using flexible substrates (such as polyimide, PI). They possess unique advantages such as light weight, thinness, flexibility, and foldability, perfectly meeting the demands of modern electronic products for miniaturization and high density. However, excessive bending can easily occur at the interface locations, and flexible FPCs lack auxiliary anti-over-bending structures. Utility Model Content

[0003] The purpose of this invention is to provide a flexible and stretchable FPC connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a flexible and stretchable FPC connector, comprising a front connector, an insulating film, a conductor layer, a rear connector, a connector protection bracket, and an anti-over-bending bracket. The conductor layer is encapsulated within the insulating film. The front connector and the rear connector are installed at the front and rear ends of the insulating film. The connector protection bracket is positioned and installed at the interface between the insulating film and the front connector and the rear connector. The anti-over-bending bracket is positioned and installed with the insulating film.

[0005] Preferably, the joint protection bracket consists of a mounting clamp, a central partition, a magnetic docking block, a metal spring, a rubber column, and an alloy limiting strip. The mounting clamp is installed at the upper and lower ends of the central partition. The magnetic docking block is embedded in the central partition axis. The side end face of the mounting clamp is positioned and installed with the rubber column through the metal spring. The alloy limiting strip is inserted into the through hole of the rubber column and the alloy limiting strip.

[0006] Preferably, the excessive bending bracket consists of an anti-excessive bending crossbar, a limiting clamp, and a mounting frame. The limiting clamp is positioned and installed at the upper and lower ends of the mounting frame body installed at one end of the anti-excessive bending crossbar.

[0007] Preferably, an anti-slip rubber strip is adhered to the inner side of the limiting clamp. Compared with the prior art, the beneficial effects of this utility model are: The joint protection bracket consists of a mounting clamp, a central partition, a magnetic docking block, a metal spring, a rubber column, and an alloy limiting pressure strip. The joint protection bracket is installed at the connection joint position. The metal spring with a certain elasticity elastically supports the rubber column and works with the alloy limiting pressure strip to stably clamp the insulating film. At this time, the insulating film will not be affected by external force and will not detach from the connection joint, thus improving stability. The over-bending bracket consists of an anti-over-bending crossbar, a limiting clamp, and a mounting frame. The diameter of the anti-over-bending crossbar is the bending limit of the insulating film. The limiting clamp stably holds the insulating film to provide structural protection during the bending and installation of the flexible and stretchable FPC. Attached Figure Description

Detailed Implementation

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0011] like Figures 1-5 As shown, a flexible and stretchable FPC connector includes a front connector 1, an insulating film 2, a conductor layer 3, a rear connector 4, a connector protection bracket 5, and an anti-over-bending bracket 6. The conductor layer 3 is encapsulated inside the insulating film 2. The front connector 1 and the rear connector 4 are installed at the front and rear ends of the insulating film 2. The connector protection bracket 5 is installed at the interface position between the insulating film 2 and the front connector 1 and the rear connector 4. The anti-over-bending bracket 6 is installed in a position relative to the insulating film 2.

[0012] The joint protection bracket 5 consists of a mounting clamp 7, a central partition 8, a magnetic docking block 9, a metal spring sheet 10, a rubber column 11, and an alloy limiting pressure strip 12. The mounting clamp 7 is installed at the upper and lower ends of the central partition 8. The magnetic docking block 9 is embedded in the central partition 8 along its axis. The side end face of the mounting clamp 7 is positioned and installed with the rubber column 11 via the metal spring sheet 10. The alloy limiting pressure strip 12 is inserted into the through hole of the rubber column 11 and the alloy limiting pressure strip 12. The metal spring sheet 10, which has a certain elasticity, elastically supports the rubber column 11 and works with the alloy limiting pressure strip 12 to stably clamp the insulating film 2. At this time, the insulating film 2 will not be affected by external force and will not detach from the connection joint, thus improving stability.

[0013] The over-bending bracket 6 consists of an anti-over-bending crossbar 13, a limiting clamp 14, and a mounting frame 15. The limiting clamp 14 is positioned at the upper and lower ends of the mounting frame 15, which is installed at one end of the anti-over-bending crossbar 13. The diameter of the anti-over-bending crossbar 13 is the bending limit of the insulating film 2. The limiting clamp 14 stably clamps the insulating film 2 to provide structural protection during the bending and installation of the flexible and stretchable FPC.

[0014] The inner side of the limiting clamp 14 is glued with anti-slip rubber, which has excellent anti-slip performance.

[0015] Specific usage: A flexible and stretchable FPC connector with a connector protection bracket installed at the connection joint. A metal spring with a certain elasticity supports the rubber column and works in conjunction with an alloy limiting pressure strip to stably clamp the insulating film. At this time, the insulating film will not be affected by external force and will not detach from the connection joint, thus improving stability. The diameter of the anti-over-bending crossbar of the bracket is the bending limit of the insulating film. The limiting clamp stably clamps the insulating film to provide structural protection during the bending and installation process of the flexible and stretchable FPC.

[0016] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
