Description

Technical Field

[0002] To meet the need for convenient cable storage, longer cables are usually designed as stretchable, coiled cables, allowing them to be pulled out when in use and coiled up when not in use. However, because round cables are prone to tangling and becoming tangled, affecting both usability and storage, flat cables are currently commonly used to make retractable cables. However, the current arrangement of the individual wires within flat cables is not ideal, resulting in a larger overall size and less convenient storage. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a portable flat cable that reduces space occupation and makes storage more convenient.

[0040] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] The embodiments of this application are described below with reference to the accompanying drawings:

[0042] refer to Figure 1 and Figure 2 The portable flat cable according to an embodiment of this application has a length direction, a width direction, and a thickness direction. The portable flat cable includes a power line group 100, a signal line group 200, and a package 300. The power line group 100 includes a positive power line 110 and a negative power line 120, and is used to transmit current. Along the width direction, the signal line group 200 is arranged between the positive power line 110 and the negative power line 120. The signal line group 200 includes multiple signal lines 210, each extending along the length direction. This means that the extension direction of each signal line 210 is parallel to the length direction of the portable flat cable. Compared to signal lines arranged in a twisted structure, this facilitates the separation of each signal line 210 for soldering during welding. Specifically, a twisted structure means that each signal line is spirally twisted along the length direction. This structure requires an additional twisting process during production, resulting in a longer production cycle and lower production efficiency. Furthermore, when it is necessary to solder the twisted signal lines to other structures, the ends of the twisted signal lines need to be rotated in the opposite direction to untwist them, ensuring proper soldering. This adds an extra preparation step before soldering. Therefore, in this application, each signal line 210 is arranged along its length, eliminating the twisting step and the pre-soldering contact twisting step during production. This makes it easier to separate each signal line 210 during production, simplifying the soldering process with other structures.

[0043] Along the thickness direction, at least two signal lines 210 are stacked, with adjacent signal lines 210 touching each other. The thickness of each signal line 210 is smaller than the thickness of the positive power line 110, and the thickness of each signal line 210 is smaller than the thickness of the negative power line 120. While ensuring the current carrying capacity of the power cable group 100, this arrangement improves the space utilization of the portable flat cable along the thickness direction. Simultaneously, the stacked arrangement of the signal lines 210 reduces the space occupied by the portable flat cable in the width direction, making it smaller and easier to store. The encapsulation 300 covers the power cable group 100 and the signal cable group 200, protecting the internal circuitry and providing insulation, thus reducing safety hazards caused by exposed wiring and extending service life.

[0044] The encapsulation 300 covering the power line group 100 and the signal line group 200 should be understood as covering at least a length of the power line group 100 and the signal line group 200 along the length direction, and completely covering the outer peripheral wall of the power line group 100 and the signal line group 200 along that length. For example, along the length direction, the ends of the power line group 100 and the signal line group 200 may be exposed outside the encapsulation 300.

[0045] refer to Figure 1 and Figure 2Specifically, the positive power line 110, negative power line 120, and each signal line 210 adopt a combination structure of wire core and sheathing layer. The wire core, as the conductive part, carries current and signal transmission, while the sheathing layer, as the insulating structure, tightly covers the wire core, effectively preventing series short circuits between different wires and ensuring circuit safety. During the production of portable flat cables, the cross-sectional area of ​​the wire core can be adjusted according to requirements to meet different transmission needs. Along the width direction of the flat cable, each signal line 210 is spaced apart from the positive power line 110 and negative power line 120. This spacing is filled by the encapsulation 300 to further enhance the electrical isolation between the power line group 100 and the signal line group 200. This structural design, on the one hand, helps reduce electromagnetic interference between different lines and improves the stability of current and signal transmission in the portable flat cable; on the other hand, the filling and fixing by the encapsulation 300 makes the internal circuit layout more regular, reducing the likelihood of wire misalignment and poor contact during bending and stretching of the flat cable, thus extending the service life of the portable flat cable.

[0046] refer to Figures 2 to 4 In other embodiments, the power line group 100 includes two positive power lines 110 and two negative power lines 120. Along the width direction, two positive power lines 110 are arranged on one side of the signal line group 200, and two negative power lines 120 are arranged on the other side of the signal line group 200. The positive power lines 110 are spaced apart from each other, from each signal line 210, from each negative power line 120, and from each other. The package 300 covers each positive power line 110, each signal line 210, and each negative power line 120 and fills the gaps. It fixes the position of each wire and provides protective insulation. By increasing the number of positive power lines 110 and negative power lines 120, it is beneficial to further enhance the current carrying capacity of the power line group 100.

[0047] refer to Figures 4 to 6 In some embodiments, at least one of the signal lines 210 and the package 300 is provided with a concave-convex structure 220. The concave-convex structure 220 is located on the side where the signal line 210 and the package 300 are in contact, so that the signal line 210 and the package 300 can make contact through the concave-convex structure 220. This is beneficial to increase the friction between the signal line 210 and the package 300, so as to better limit the relative movement between the two and avoid signal transmission abnormalities caused by internal line displacement.

[0048] Specifically, the raised / lower structure 220 is disposed on the coating layer of the signal line 210, and this structure is formed by changing the surface roughness of the coating layer. During the production process, the surface shape of the wire pressing die can be adjusted, and the raised / lower structure 220 is directly pressed out while the coating layer is being pressed, without the need for additional production steps. This process maintains the original production flow while ensuring production efficiency. Simultaneously, since the raised / lower structure 220 is formed on the coating layer, it effectively increases the friction between the signal line 210 and the package 300 when in contact with the package 300, thereby better limiting the relative movement between the signal line 210 and the package 300 and improving the tensile strength of the flat wire.

[0049] refer to Figures 4 to 6 In other embodiments, the positive power line 110 and the negative power line 120 are provided with a concave-convex structure 220. When the portable flat cable is subjected to a tensile force, the interlocking action between the concave-convex structures 220 can restrict the relative movement between the power cable assembly 100 and the package 300, preventing the power cables from sliding or shifting inside the package 300. This is beneficial to improving the overall tensile strength of the portable flat cable. Similarly, this structure does not require significant modifications to existing manufacturing processes, ensuring production efficiency.

[0050] The method for forming the portable flat wire in this application is as follows:

[0051] Twisting process: The multiple conductors used in a single-strand wire core (including signal line 210, positive power line 110, and negative power line 120) are twisted together to form single-strand conductors respectively;

[0052] Insulation treatment: Each single conductor is individually coated with adhesive for insulation treatment. When the adhesive layer is used for insulation, the surface roughness of the adhesive layer is adjusted to form an uneven structure 220.

[0053] Wire assembly processing: Arranging and combining multiple single-strand conductors that have been coated with rubber;

[0054] Molding process: The signal line group 200 is placed between the positive power line 110 and the negative power line 120, and the package is formed by wrapping the opening through the square mold of the extruder.

[0055] refer to Figures 4 to 6 In some embodiments, the concave-convex structure 220 includes a plurality of protrusions 221, which are spaced apart. When the portable flat cable is bent, the internal material deforms due to stress. The spacing between the protrusions 221 can provide buffer space for the deformation of the internal material, so as to avoid damage to the material due to excessive compression, which is beneficial to extending the service life of the portable flat cable.

[0056] Specifically, the protrusions 221 can be strip-shaped, triangular, circular, square, or other shapes. Taking a strip-shaped protrusion 221 as an example, the protrusions 221 extend along the width direction and are spaced apart along the length direction. Thus, when the portable flat cable is stretched along its length, the spaced strip-shaped protrusions 221 can form a mutually restrictive structural relationship with the package 300, effectively limiting the relative movement between the signal line 210 and the package 300. Each protrusion 221 can restrict the movement between each signal line 210 and the package 300, ensuring the tensile strength of the portable flat cable and preventing the signal line 210 from shifting or detaching under stress, thus ensuring the stability of the internal circuit connection. In addition, while ensuring structural strength, the spaced strip-shaped protrusions 221 can distribute tensile stress more evenly on each protrusion 221, making the flat cable more uniformly stressed under tension, further enhancing the durability of the portable flat cable.

[0057] refer to Figures 4 to 6 In other embodiments, both the signal line 210 and the package 300 are provided with a protrusion-contact structure 220. The protrusion-contact structure 220 is located on the side of the signal line 210 that is in contact with the package 300. The protrusion-contact structure 220 includes a plurality of spaced protrusions 221. The protrusions 221 on the signal line 210 can be embedded into the spaces between the protrusions 221 on the package 300, and vice versa, thereby forming an interlocking structure at the contact interface. This is beneficial for further increasing the contact area and friction between the signal line 210 and the package 300, and can more effectively limit the relative movement between them.

[0058] refer to Figure 7 and Figure 8 In some embodiments, the extension direction of each protrusion 221 is arranged at an angle relative to both the length and width directions, and the protrusions 221 are arranged at intervals, so that the protrusions 221 of the signal line 210 and the protrusions 221 of the package 300 form an interlocking connection. When the portable flat cable is pulled by an external force along the length direction, the inclined strip protrusions 221 can effectively prevent the relative sliding between the signal line 210 and the package 300, which is beneficial to enhancing the tensile strength of the flat cable. When the flat cable is subjected to a torsional force, it can also limit the displacement of the signal line 210 in the width direction, thereby providing a certain anti-torsion capability, so as to further improve the overall performance of the portable flat cable.

[0059] refer to Figures 4 to 6In some embodiments, a concave-convex structure 220 is provided on the side where each signal line 210 is in contact with the others, so that adjacent signal lines 210 can make contact through the concave-convex structure 220, effectively limiting the relative movement between adjacent signal lines 210 and keeping the signal line group 200 as a whole. That is, when the portable flat cable is pulled, the concave-convex structure 220 can keep each signal line 210 in a tight state, avoiding the breakage or poor contact of a single signal line 210 due to excessive pulling, thereby further extending the service life of the portable flat cable.

[0060] refer to Figure 7 In some embodiments, the multiple signal lines 210 include a first signal line 211, a second signal line 212, and a third signal line 213. Along the width direction, the first signal line 211 and the second signal line 212 are arranged side by side. Along the thickness direction, the third signal line 213 is stacked on top of the first signal line 211 and the second signal line 212, that is, the third signal line 213 is stacked on top of the first signal line 211 and the second signal line 212 along the thickness direction, so that the cross-sections of the first signal line 211, the second signal line 212, and the third signal line 213 are arranged in a triangular shape.

[0061] Alternatively, the multiple signal lines 210 include a first signal line 211, a second signal line 212, a third signal line 213, and a fourth signal line 214. Along the width direction, the first signal line 211 and the second signal line 212 are arranged side by side, and the third signal line 213 and the fourth signal line 214 are arranged side by side. Along the thickness direction, the first signal line 211 and the third signal line 213 are stacked, and the second signal line 212 and the fourth signal line 214 are stacked. The cross-sections of the first signal line 211, the second signal line 212, the third signal line 213, and the fourth signal line 214 are arranged in a rectangular shape.

[0062] It should be noted that the above-mentioned cross-sections are cross-sections formed by cutting each signal line 210 along a plane perpendicular to the length direction, and the shape formed by the cross-sections is the shape formed by connecting the centers of each cross-section. In addition, the number and arrangement of the signal lines 210 in this embodiment should not be limited to this application. Depending on the number of signal lines 210, the stacking method of each signal line 210 can be adaptively adjusted to further make the portable flat cable structure more compact.

[0063] In this application, since the positive power line 110 and the negative power line 120 need to carry current, their thickness is relatively large. The signal line 210 can make full use of the space in the thickness direction by stacking at least two of them along the thickness direction. This effectively improves the space occupation problem caused by the dispersed arrangement of the signal line 210 in the width direction. On the one hand, the stacking reduces the lateral space occupied by the signal line 210 in the width direction. Combined with the thickness characteristics of the positive power line 110 and the negative power line 120, the overall cross-sectional area of ​​the portable flat cable can be reduced, making the structure more compact and improving the convenience of storing the flat cable in the main body of the device. On the other hand, the triangular or rectangular cross-section layout allows the package 300 to uniformly cover the internal circuitry, reducing the stress concentration problem caused by irregular circuit arrangement and enhancing the overall structural stability of the flat cable.

[0064] Therefore, compared to arranging each signal line 210 along the width direction, by stacking at least two signal lines 210 along the thickness direction, the space occupied in the width direction can be reduced. In addition, in combination with the characteristics of the positive power line 110 and the negative power line 120 having a larger thickness due to carrying current, the size of the portable flat cable can be further reduced without affecting the function of the portable flat cable.

[0065] refer to Figures 1 to 4 In some embodiments, the thickness of the signal line group 200 is less than or equal to the thickness of the power line group 100 along the thickness direction. Specifically, along the width direction, the signal line group 200 is arranged between the positive power line 110 and the negative power line 120, and multiple signal lines 210 are stacked and attached along the thickness direction. Thus, the signal line group 200 can make full use of the space in the thickness direction. On the one hand, it avoids occupying too much area in the width direction, and on the other hand, it avoids protruding outward relative to the power line group 100 in the thickness direction, causing additional occupation of thickness space. Thus, the structure of the portable flat cable is more compact, so as to further optimize the internal space layout of the portable flat cable.

[0066] In addition, if the maximum thickness of the signal line group 200 is less than the thickness of the power line group 100 along the thickness direction, the encapsulation thickness of the package 300 on the signal line group 200 can be increased, providing more reliable protection for the signal line group 200 and reducing the risk of external force damage caused by uneven local thickness.

[0067] refer to Figures 1 to 4In some embodiments, each signal line 210 is bonded to the package 300 to further enhance the connection stability between the signal line 210 and the package 300. Specifically, adhesive can be filled between the encapsulation layer of the signal line 210 and the package 300 to tightly connect them through the adhesive effect; or, materials with adhesive properties can be used to prepare the encapsulation layer of the signal line 210 and the package 300, for example, the encapsulation layer can be made of thermoplastic elastomer and the package 300 can be made of thermoplastic polyurethane rubber, utilizing the compatibility between the materials to achieve natural bonding. Both methods can ensure the insulation performance of the encapsulation layer while forming a reliable connection between the signal line group 200 and the package 300. Thus, the signal line 210 and the package 300 are tightly bonded together by the adhesive, which can effectively limit the relative movement between the two and avoid signal transmission abnormalities or short circuit risks caused by internal circuit displacement. When the portable flat cable is pulled or bent by external force, the adhesive structure can disperse the stress and reduce the slippage between the signal line 210 and the package 300, which is beneficial to improving the structural stability and durability of the portable flat cable.

[0068] refer to Figures 1 to 4 In some embodiments, the thickness of the portable flat cable is 1mm to 2.5mm. For example, the thickness of the portable flat cable can be any of the following dimensions: 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, or 2.5mm. It can also be a range of any two of the above thickness dimensions as endpoint values. Limiting the upper limit of the thickness of the portable flat cable makes the structure of the portable flat cable more compact and the portable flat cable more portable. Limiting the lower limit of the thickness of the portable flat cable is used to ensure the cross-sectional dimensions of the power cord assembly, thereby ensuring the current carrying capacity of the portable flat cable.

[0069] And / or, the width of the portable flat cable is 3.5mm to 10mm. For example, the width of the portable flat cable can be any of the following dimensions: 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, or 10mm. Alternatively, any two of the above thickness dimensions can be used as a range of endpoint values ​​to limit the upper limit of the width of the portable flat cable. This allows the portable flat cable to occupy less lateral space when stored. Limiting the lower limit of the width of the portable flat cable provides the necessary space guarantee for the layout of power cord groups and signal cord groups, which is beneficial to better balance space occupation and the current and signal transmission performance of the portable flat cable.

[0070] refer to Figure 1 and Figure 2In other embodiments, along the thickness direction, the outer wall of at least one side of the package 300 is provided with an anti-slip structure 310. The anti-slip structure 310 extends along the length direction. After the portable flat cable is wound up and arranged, the adjacent parts from the inside to the outside come into contact with each other. The anti-slip structure 310 can increase the friction between the inside and outside of the portable flat cable, effectively limiting the relative sliding between adjacent parts, which is beneficial to maintaining the compactness and stability of the flat cable after winding.

[0071] refer to Figures 1 to 8 An electronic device according to an embodiment of this application includes a device body and a portable flat cable as described in any of the above embodiments. The portable flat cable is connected to the device body, enabling current and / or information transmission between different electronic devices. For example, one end of the portable flat cable is fixedly connected inside the device body and is coiled and stored in a storage space within the device body. When in use, the user can pull out a suitable length of the portable flat cable from the device body and plug the other end into another electronic device to complete the electrical transmission operation. Compared with traditional thick flat cables, the thickness of the portable flat cable in this application occupies less internal space in the device body when stored, which is beneficial to reducing the overall size of the electronic device and improving its portability. At the same time, the flat cable shape makes it less likely for the cable to tangle when coiled and stored, and the bending angle of the cable is more natural when pulled out for use, which helps to reduce cable damage caused by excessive bending and extends its service life.

[0072] Among them, electronic devices can be power banks, chargers, power strips, desktop chargers, and other electronic devices.

[0073] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
