Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a ribbon cable and a display device. Background Technology

[0002] A flat panel cable (FPC) is a flexible cable that connects a display screen to a motherboard or other electronic components. It is commonly used to connect the display screen to the motherboard in display devices such as mobile phones, tablets, or computers.

[0003] Due to the limited internal space of display devices and the different orientations of the display screen interface and motherboard interface, ribbon cables are generally routed using a bent-bend method. However, the bends in the ribbon cables lack protective structures. When the display device is disassembled and repaired, the adhesive is melted by heating and the display screen is pulled out using a suction cup. Since the ribbon cable is still connected to the display screen and motherboard, the suction cup can generate instantaneous tearing force and random twisting during the removal of the display screen, increasing the risk of damage to the bends in the ribbon cable. Utility Model Content

[0004] The main technical problem solved by this utility model embodiment is to provide a ribbon cable and display device that can reduce the risk of damage at the bends of the ribbon cable.

[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0031] A flat panel cable (FPC) is a flexible cable that connects a display screen to a motherboard or other electronic components. It is commonly used to connect the display screen to the motherboard in display devices such as mobile phones, tablets, or computers.

[0032] Due to the limited internal space of display devices and the different orientations of the display screen interface and motherboard interface, ribbon cables are generally routed using a bent-bend method. However, the bends in the ribbon cables lack protective structures. When the display device is disassembled and repaired, the adhesive is melted by heating and the display screen is pulled out using a suction cup. Since the ribbon cable is still connected to the display screen and motherboard, the suction cup can generate instantaneous tearing force and random twisting during the removal of the display screen, increasing the risk of damage to the bends in the ribbon cable.

[0033] In view of this, the present invention provides an embodiment of a ribbon cable 100, including a cable body 1 and a protective member 2. When the cable body 1 is subjected to external force to stretch or twist, the protective member 2 tightens the bent portion 13 of the cable body 1. When the protective member 2 is tightened to the point of breakage, it can offset the instantaneous tearing force and reduce the risk of damage to the bent portion 13 of the cable body 1.

[0034] For the above-mentioned ribbon cable 100, please refer to Figure 1 and Figure 2 The ribbon cable 100 includes a cable body 1 and a protective member 2. The cable body 1 includes a first segment 11 and a second segment 12 connected together, with the first segment 11 and the second segment 12 arranged at a preset angle. The first segment 11 and the second segment 12 together form a bend 13. The protective member 2 is disposed at the inner corner of the bend 13. The protective member 2 has a first end 21 and a second end 22 arranged opposite to each other. The first end 21 is connected to the first segment 11, and the second end 22 is connected to the second segment 12. The protective member 2 is used to tighten the bend 13 first when the cable body 1 is stretched or twisted. It should be noted that the first segment 11 and the second segment 12 are arranged at a preset angle, where the preset angle refers to an angle less than 180 degrees. In this way, when the cable body 1 is subjected to external force to stretch or twist, the protective member 2 tightens the bend 13 of the cable body 1 first. When the protective member 2 is tightened to the point of breakage, it can offset the instantaneous tearing force and reduce the probability of the bend 13 of the cable body 1 tearing or breaking.

[0035] For the aforementioned line body 1, along the line width direction of line body 1, line body 1 includes two electromagnetic shielding layers, multiple insulating layers, and multiple conductive layers. The multiple insulating layers are disposed between the two electromagnetic shielding layers, and a conductive layer is disposed between any two adjacent insulating layers. For example, in some embodiments, line body 1 includes two electromagnetic shielding layers, six insulating layers, and five conductive layers. The six insulating layers are disposed between the two electromagnetic shielding layers, and a conductive layer is bonded between any two adjacent insulating layers by adhesive.

[0036] The protective element 2 is fan-shaped or arc-shaped, covering the bottom of the inner corner of the bend 13. It is integrally formed on the bottom of the inner corner of the bend 13 of the thread body 1, meaning it fills a portion of the bend 13. By integrally forming the protective element 2 on the thread body 1, the structural reliability of the connection between the thread body 1 and the protective element 2 is improved, reducing the risk of the protective element 2 detaching or loosening from the thread body 1 due to external forces. It is understood that the protective element 2 includes, but is not limited to, covering the bottom of the inner corner of the bend 13. For example, in some other embodiments, the protective element 2 covers the inner corner of the bend 13, meaning it fills the entire area of ​​the bend 13 of the thread body 1.

[0037] Regarding the aforementioned protective element 2, the material of protective element 2 is a flexible material, for example, the material of protective element 2 is PI (polyimide). Protective element 2 includes at least two PI layers, which are bonded together by an adhesive. Any one of the PI layers is integrally formed on the wall of the bending groove 11 of the line body 1. In this way, protective element 2, with its good flexibility, can adaptably bend or twist in different directions following the line body 1 during use. It is understood that the material of protective element 2 includes, but is not limited to, PI (polyimide). For example, in some other embodiments, the material of protective element 2 is a flexible material such as polyester, polyurethane, silicone, or composite materials.

[0038] For the aforementioned protective element 2, please refer to Figure 1 and Figure 2 The protective component 2 is provided with a guide groove 23, which is located between the first end 21 and the second end 22. The guide groove 23 extends from the end of the protective component 2 away from the inner corner of the bending portion 13 toward the end of the protective component 2 near the inner corner of the bending portion 13. The guide groove 23 is used to guide the protective component 2 to break along a preset direction.

[0039] For the aforementioned protective element 2, please refer to Figure 1 and Figure 2 The guide groove 23 is V-shaped. It is understood that the guide groove 23 includes, but is not limited to, a V-shaped configuration; for example, in some other embodiments, the guide groove 23 is U-shaped.

[0040] For the aforementioned protective element 2, please refer to Figure 1 and Figure 2 The protective component 2 is provided with a fracture guide structure 24, which is located between the first end 21 and the second end 22. Furthermore, the fracture guide structure 24 is closer to the bottom of the inner corner of the bend 13 than the guide groove 23. In this manner, the fracture guide structure 24 can further guide the protective component 2 to fracture along a predetermined direction, thereby offsetting the instantaneous tearing force along the predetermined direction, reducing the concentration of instantaneous tearing force, and lowering the risk of damage to the bend 13 of the line 1.

[0041] For the fracture guidance structure 24 mentioned above, please refer to Figure 3 The fracture guide structure 24 includes multiple hollow holes 241, which are spaced apart and arranged in a straight line.

[0042] In this way, multiple perforated holes 241 are arranged at intervals. When a break occurs, the connection between any two adjacent perforated holes 241 breaks one by one under the action of instantaneous tearing force, thus gradually offsetting the instantaneous tearing force.

[0043] In some embodiments, please refer to Figure 4 and Figure 5 The number of fracture guide structures 24 is multiple, and the multiple fracture guide structures 24 are arranged at intervals, radiating outwards from the bottom of the guide groove 23. In this way, the protective component 2 can be guided to fracture in multiple places along a preset direction, so that the instantaneous tearing force is dispersed and canceled out at different angles, reducing the concentration of instantaneous tearing force at any position, and making the cancellation of instantaneous tearing force more reliable.

[0044] In some embodiments, please refer to Figure 6 Multiple fracture guide structures 24 are arranged at intervals and are flared in shape. The flared openings of the structures form a preset angle with the opening of the guide groove 23. It should be noted that the preset angle between the flared openings and the opening of the guide groove 23 refers to an angle less than 180 degrees. Through this method, the protective component 2 can be guided to fracture at multiple points along a preset direction, so that the instantaneous tearing force is dispersed and offset at different angles, reducing the concentration of instantaneous tearing force at any single location, and making the offsetting of instantaneous tearing force more reliable.

[0045] For the above-mentioned ribbon cable 100, please refer to Figure 1 The number of bends 13 is multiple, and the multiple bends 13 are spaced apart along the extension direction of the line body 1. The protective members 2 are correspondingly provided with the bends 13. For example, in some embodiments, the number of protective members 2 is multiple, and one protective member 2 is provided with one bend 13. In this way, the extension length of the line body 1 can be increased, and the probability of the line body 1 bending or twisting in any direction can be increased.

[0046] It is understandable that when there are multiple protective elements 2, the fracture guidance structure 24 of the multiple protective elements 2 can be the same or different.

[0047] This utility model embodiment provides a ribbon cable 100, including a cable body 1 and a protective member 2. The cable body 1 includes a first segment 11 and a second segment 12 connected to each other, with the first segment 11 and the second segment 12 arranged at a preset angle. The first segment 11 and the second segment 12 together form a bending portion 13. The protective member 2 is disposed at the inner corner of the bending portion 13. The protective member 2 has a first end 21 and a second end 22 arranged opposite to each other. The first end 21 is connected to the first segment 11, and the second end 22 is connected to the second segment 12. The protective member 2 is used to tighten the bending portion 13 first when the cable body 1 is stretched or twisted. It should be noted that the first segment 11 and the second segment 12 are arranged at a preset angle, where the preset angle refers to an angle less than 180 degrees. In this way, when the cable body 1 is subjected to external force to stretch or twist, the protective member 2 tightens the bending portion 13 of the cable body 1 first. When the protective member 2 is tightened to the point of breakage, it can offset the instantaneous tearing force and reduce the probability of the bending portion 13 of the cable body 1 tearing or breaking.

[0048] This utility model also provides an embodiment of a display device, including a housing, a circuit board, a display screen, and the aforementioned ribbon cable 100.

The ribbon cable 100 is disposed in the receiving cavity, one end of the ribbon cable 100 is connected to the display screen, and the other end of the ribbon cable 100 is connected to the circuit board. For the specific structure and function of the ribbon cable 100, please refer to the above embodiments; they will not be repeated here.

[0049] Specifically, the aforementioned ribbon cable 100 includes a first interface 3 and a second interface 4. The first interface 3 is connected to one end of the cable body 1 and is electrically connected to the display screen.
