Description

Technical Field

[0001] The present application relates to the field of flexible flat cables, and in particular to a flexible flat cable structure with an indication function. Background Art

[0002] Flexible cables are mainly used for connecting board ends. They have been widely used in many related electrical products due to their high-speed transmission, low electromagnetic waves, and light weight and small size.

[0003] The current flexible cable includes a base film and a silver paste wire disposed on the base film. A connector is disposed at the end of the silver paste wire for connecting to other sockets.

[0004] In the actual connection process, plugging the front side of the flexible cable will form a connection, while plugging the back side will cause the line to be disconnected, and may even cause serious consequences such as circuit burning. However, there is no structure on the existing flexible cable to indicate the front and back sides, and there is room for improvement. Utility Model Content

[0005] In order to prevent the flexible cable from being inserted backwards, causing the circuit to become non-conductive or even burn out, the present application provides a flexible cable structure with an indication function.

[0006] The flexible cable structure with indication function provided in this application adopts the following technical solution:

[0007] A flexible cable structure with an indication function comprises a base film and a silver paste conductor arranged on the base film, wherein an indication ink block is printed on the silver paste conductor.

[0008] By adopting the above technical solution, an indicator ink block is printed on the silver paste conductor, which can indicate the front side of the flexible cable and serve as an indicator for the user, thereby helping to prevent the flexible cable from being reversely inserted, resulting in the circuit being unable to conduct or even burning.

[0009] Preferably, an insulating ink layer is also printed on the surface of the silver paste conductor.

[0010] By adopting the above technical solution, an insulating ink layer is printed on the surface of the silver paste conductor, which can play an insulating role for the flexible cable. In practice, the insulating ink layer is a transparent layer and will not block the indicating function of the indicating ink block.

[0011] Preferably, the base film is bonded with a film on the insulating ink layer.

[0012] By adopting the above technical solution, the film is bonded to the insulating ink layer, which can protect the surface of the silver paste wire and help prevent scratches on the surface of the silver paste wire.

[0013] Preferably, a plurality of indicator ink blocks are provided.

[0014] By adopting the above technical solution, a plurality of indicating ink blocks are provided, and the indicating effect is more obvious, so that the user can easily distinguish the front and back sides of the flexible cable.

[0015] Preferably, all the indicator ink blocks are arranged in a linear distribution.

[0016] By adopting the above technical solution, all the indicating ink blocks are arranged in a linear distribution, and the indicating effect is more significant, which makes it easier for users to distinguish the front and back sides of the flexible cable.

[0017] Preferably, a connecting sheet is adhered to a side of the bottom film away from the silver paste wire.

[0018] By adopting the above technical solution, when plugging and unplugging the flexible cable, the user can pinch the connecting piece to perform the plugging and unplugging action. Since the flexible cable itself is flexible, if the flexible cable itself is directly pinched, the flexible cable will be deformed during plugging and unplugging, affecting the plugging and unplugging efficiency.

[0019] Preferably, paddles are provided on both sides of the connecting piece.

[0020] By adopting the above technical solution, when pulling out the flexible flat cable from the socket, the user can use a finger to push the paddle outwards to easily pull out the flexible flat cable.

[0021] Preferably, a reinforcing sheet is further provided at the connection between the paddle and the connecting sheet.

[0022] By adopting the above technical solution and using the reinforcing sheet, the connection strength of the connection between the plectrum and the connecting sheet is improved, which helps to prevent damage to the connection between the plectrum and the connecting sheet when the plectrum is pushed outward.

[0023] Preferably, paddles are provided on both sides of the bottom film.

[0024] Preferably, a reinforcing sheet is further provided at the connection between the paddle and the bottom sheet.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The indicator ink block printed on the surface of the silver paste wire plays an indicator role, which is convenient for users to identify the front and back sides of the flexible cable, thereby helping to prevent the flexible cable from being reversely inserted, resulting in circuit failure or even burning;

[0027] 2. With the help of the connecting piece, the user can plug and unplug the flexible cable by pinching the connecting piece, which is more convenient;

[0028] 3. When pulling out the flexible cable, the user can use his fingers to push the paddle outwards to easily pull out the flexible cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1 This application is described in further detail.

[0032] The embodiment of the present application discloses a flexible cable structure with an indication function.

[0033] Reference Figure 1 The flexible cable structure with indication function includes a base film 1 and a silver paste conductor 2 printed on the base film 1. An indication ink block 3 is printed on the silver paste conductor 2, indicating the front side of the flexible cable, which serves as an indication for users and helps prevent the reverse connection of the flexible cable, affecting the conduction and even life of the circuit.

[0034] The film 1 is also printed with an insulating ink layer 4 on the surface of the silver paste conductor 2. The insulating ink layer 4 is made of a translucent material and covers the indicating ink block 3 without blocking the indicating effect of the indicating ink block 3. The insulating ink layer 4 covers the surface of the silver paste conductor 2 and plays an insulating role for the flexible cable.

[0035] The film 5 is bonded to the insulating ink layer 4 on the bottom film 1. The film 5 protects the silver paste wire 2 and helps prevent accidental scratches that may damage the surface of the silver paste wire 2.

[0036] A plurality of indicating ink blocks 3 are provided and distributed in a linear array, so that the indicating function is more significant, and the user can easily identify the front and back sides of the flexible cable, and further prevent the user from plugging the flexible cable in reverse.

[0037] A connecting piece 6 is adhered to the side of the bottom film 1 away from the silver paste wire 2. The connecting piece 6 is made of plastic and has a certain hardness. When plugging and unplugging the flexible cable, the user can pinch the connecting piece 6 to perform the plugging and unplugging action, which is faster and more convenient. Due to the flexible properties of the flexible cable, if the flexible cable itself is directly pinched, the part pinched by the fingers and the flexible cable is very likely to be deformed during plugging and unplugging, resulting in the inability to align the flexible cable with the socket, affecting the plugging and unplugging efficiency.

[0038] Both sides of the connecting piece 6 are integrally formed with a paddle 7, which is in a rectangular shape. When pulling out the flexible cable from the socket, the user can use a finger to push the paddle 7 outwards and cooperate with the connecting piece 6 to easily pull out the flexible cable.

[0039] A reinforcing sheet 8 is integrally formed at the connection between the paddle 7 and the connecting sheet 6 to improve the connection strength between the paddle 7 and the connecting sheet 6 and to help prevent damage to the connection between the paddle 7 and the connecting sheet 6 when the paddle 7 is pushed outward.

[0040] In addition, paddles 7 are integrally formed on both sides of the bottom film 1, and reinforcing sheets 8 are integrally formed at the connection between the paddles 7 and the bottom film 1. When the connecting sheet 6 and the bottom film 1 are bonded together, the paddles 7 on the bottom film 1 and the paddles on the connecting sheet 6 fit together to form an integral paddle 7, which improves the structural strength of the paddle 7 and facilitates the user to plug and unplug the flexible cable.

[0041] The implementation principle of a flexible cable structure with an indication function in an embodiment of the present application is as follows: a plurality of indication ink blocks 3 are printed on the surface of the silver paste conductor 2 to indicate the front and back sides of the flexible cable, reminding the user of the correct plugging direction, which helps to prevent reverse plugging, resulting in circuit non-conduction or even burning; a film 5 is bonded to the surface of the silver paste conductor 2 to protect the silver paste conductor 2 and prevent scratches; the connecting piece 6 has a certain hardness, and the user pinches the connecting piece 6 to prevent the flexible cable print itself from being deformed and affecting the plugging efficiency.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
