Description

Technical Field

[0001] The utility model relates to the technical field of FFC flexible cable detection, in particular to a device for detecting the service life of an FFC flexible cable. Background Technique

[0002] An FFC flexible cable is a flexible flat cable, usually composed of multiple strands of wires and insulating materials. The FFC flexible cable is usually very flexible and has a flat shape, making it easy to bend and fold. It is suitable for occasions with narrow spaces or complex wiring requirements. Due to its flat structure and flexible material, the FFC flexible cable is thinner and lighter than traditional round cables, which is beneficial for saving space and reducing the weight of the device. The wires of the FFC flexible cable are usually densely arranged, enabling it to achieve high-density connections and being suitable for devices that need to connect a large number of electronic components or have dense leads. The FFC flexible cable has good electrical conductivity and insulation performance, can effectively transmit electrical signals, and at the same time ensure the stability and reliability of the signals. The FFC flexible cable is widely used in various electronic devices.

[0003] Before the FFC flexible cable is put into use, it is necessary to conduct electrical performance tests and tensile bending tests to determine whether the service life of the FFC flexible cable meets the requirements. When the detection device conducts the tensile bending test, it is not easy to fix and adjust the FFC flexible cable. If the fixing force is too large, it is easy to damage the FFC flexible cable. If the fixing force is too small, it is easy to cause the FFC flexible cable to slide during the stretching process. The connection part between the FFC flexible cable and the electrical signal detector is prone to certain damage. Damage to the connection position or internal damage to the FFC flexible cable will seriously affect the electrical performance test, and the experimental data is prone to deviation, affecting the detection result of the FFC flexible cable. To solve the above problems, a device for detecting the service life of an FFC flexible cable is proposed. Content of the Utility Model

Detailed Embodiment

[0017] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0018] Refer to Figure 1-2 As shown, a device for detecting the service life of an FFC flexible flat cable includes a detection platform 1. Support legs 2 are fixedly connected to the four corner positions on the lower side of the detection platform 1. An electrical signal generator 3 is fixedly installed at the left end on the upper side of the detection platform 1 to effectively emit detection electrical signals. An electrical signal receiver 4 is fixedly installed at the right end on the upper side of the detection platform 1 to effectively receive electrical signals and analyze detection data. The output end of the electrical signal generator 3 is clamped with a flexible flat cable 5, and the right side of the flexible flat cable 5 is clamped with the input end of the electrical signal receiver 4.

[0019] Specifically, a T-shaped sliding groove 6 is opened at the upper center position of the detection platform 1. A fixing block 7 is fixedly connected to the right end of the electric signal generator 3 on the upper side of the detection platform 1. A first wire passing port 8 is penetrated and opened at the center position on the right side of the fixing block 7. A pressing plate 9 is slidably connected inside the first wire passing port 8. The pressing plate 9 is made of a material with a certain friction and will not damage the surface of the flexible cable 5, such as rubber or other materials. A threaded rod 10 is threadedly connected to the upper center position of the fixing block 7. The lower end of the threaded rod 10 penetrates the upper side of the fixing block 7 and is rotatably connected to the upper side of the pressing plate 9. A knob 11 is fixedly connected to the upper side of the threaded rod 10. A T-shaped slider 12 is slidably connected inside the T-shaped sliding groove 6. A sliding block 13 is fixedly connected to the upper side of the T-shaped slider 12. A push rod 14 is fixedly installed at the center position on the right side of the detection platform 1. The output end of the push rod 14 is fixedly connected to a connecting rod 15, which effectively exerts a stretching effect on the sliding block 13.

[0020] Specifically, a second wire passing port 16 is penetrated and opened at the center position on the right side of the sliding block 13. A rotating rod 17 is rotatably connected to the upper end inside the second wire passing port 16. A fixing roller 18 is fixedly connected to the surface of the rotating rod 17. A plurality of fixing bumps 19 are fixedly connected to the right side of the fixing roller 18. The fixing bumps 19 are made of a material with a certain friction and will not damage the surface of the flexible cable 5, such as rubber or other materials. The front end of the rotating rod 17 penetrates the front end of the second wire passing port 16 and is fixedly connected to a rotating handle 20. A limiting hole 21 is opened at the lower front side of the sliding block 13. A sliding rod 22 is slidably connected to the right rear end of the rotating handle 20. The front end of the sliding rod 22 penetrates the rear side of the rotating handle 20 and is fixedly connected to a push-pull handle 23. The end of the sliding rod 22 can be engaged with the inside of the limiting hole 21, effectively preventing the rotating rod 17 from rotating during the tensile test, ensuring that the fixing bumps 19 are in contact with the upper side of the flexible cable 5 and have sufficient friction. A tensile force sensor 24 is fixedly installed at the upper right end of the sliding block 13. The left end of the connecting rod 15 is fixedly connected to the right side of the tensile force sensor 24.

[0021] Working principle: After the left end of the flexible flat cable 5 is clamped to the output end of the electrical signal generator 3, the right end of the flexible flat cable 5 is passed through the first wire passing port 8 and the second wire passing port 16 and clamped to the input end of the electrical signal receiver 4. By inputting the corresponding detection electrical signal through the electrical signal generator 3, the electrical signal receiver 4 collects and analyzes the detection electrical signal. When a tensile and bending test needs to be carried out, rotate the knob 11, and the threaded rod 10 and the pressing plate 9 move downward to fix the left end of the flexible flat cable 5. Rotate the rotating handle 20 to rotate the fixed convex block 19 to abut against the upper side of the flexible flat cable 5. When the rotating handle 20 rotates to be vertically downward, push the push-pull handle 23 to make the rear end of the sliding rod 22 engage with the inside of the limiting hole 21. When a tensile test needs to be carried out on the flexible flat cable 5, the push rod 14 controls the connecting rod 15 and the sliding block 13 to move to the right, and the tensile force sensor 24 monitors the tensile force in real time and transmits it to the electrical signal receiver 4 for centralized analysis. When a bending test needs to be carried out on the flexible flat cable 5, a reciprocating stretching instruction within a certain range is set for the push rod 14, and the sliding block 13 performs repeated sliding movements synchronously. The flexible flat cable 5 between the fixed block 7 and the sliding block 13 will undergo a bending test. The number of bending times and the electrical signal receiving state of the flexible flat cable 5 are uniformly statistically analyzed by the electrical signal receiver 4.
