Technical Field
[0001] This utility model relates to the field of computer connection cable technology, specifically a bend-resistant computer connection cable. Background Technology
[0002] Computer cables are cables that connect various external devices to the computer host. They are divided into monitor cables, power cables, and data cables. They are one of the most frequently used items in daily life. In daily use, cables need to withstand large bending angles frequently. Prolonged bending may cause damage to the outer surface and the internal wire cores, resulting in a reduction in the lifespan of the cable. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a bend-resistant computer cable, solving the problem that current computer cables are prone to frequent bending during use, leading to a reduced cable lifespan.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, the present invention provides the following technical solution: a bend-resistant computer connection cable, comprising multiple wire cores arranged in parallel to form a wire core bundle, a wrapping layer tightly wrapping the wire cores on the outside of the wire core bundle, a protective strip in the middle of the wire core bundle assisting in resetting as the wire core bundle bends, a protective layer on the outside of the wrapping layer, and a sealing layer on the outside of the protective layer.
[0007] The protective strip includes an elastic bending strip disposed in the middle of the core bundle, and the outer side of the elastic bending strip is provided with several cross-shaped reinforcing ribs;
[0008] The protective layer includes a rubber layer covering the outside of the wrapping layer, and the rubber layer contains spiral filaments arranged in a spiral pattern that follows the shape of the rubber layer.
[0009] Preferably, the elastic bending strip is arranged in parallel with the multiple wire cores, and the elastic bending strip is placed in the middle of the multiple wire cores. The elastic bending strip has the elasticity to return to its original position when the connecting wire is bent as a whole.
[0010] Preferably, the cross-shaped reinforcing ribs are in multiple groups, fixedly and vertically arranged on the outside of the elastic bending strip, with the edges of the cross-shaped reinforcing ribs extending to the intersection of multiple wire cores, and a gap is left between two adjacent groups of cross-shaped reinforcing ribs when the elastic bending strip is bent.
[0011] Preferably, the inner wall of the rubber layer is tightly fitted to the wrapping layer, the outer wall of the rubber layer is tightly fitted to the inner wall of the cover, and the spiral wire is fixedly connected to the side wall of the rubber layer.

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a bend-resistant computer connection cable, which has the following beneficial effects:
[0016] By setting a protective strip in the core of the connecting wire, when the connecting wire is bent, the elastic bending strip in the protective strip bends synchronously with the bending of the wire. The cross-shaped reinforcing rib on the outside of the elastic bending strip can effectively prevent the bending angle of the elastic bending strip from being too small, so that the overall bending angle of the connecting wire tends to be gentle, thus protecting the connecting wire.
[0017] At the same time, a protective layer with spiral wires is set. When the connecting wire is bent as a whole, the spiral wires cooperate with the bending of the connecting wire. When the external bending force is removed, the connecting wire returns to an upright state because the spiral wires are spiral-shaped and made of metal memory material, thus avoiding damage caused by the connecting wire being bent for too long.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] Figure 1-3 In one embodiment of this utility model, a bend-resistant computer connection cable includes multiple wire cores 1, which are arranged in parallel to form a wire core bundle 2. A wrapping layer 3 is provided on the outside of the wire core bundle 2 to tightly wrap the wire cores 1. A protective strip 4 is provided in the middle of the wire core bundle 2 to assist in restoring the wire core bundle 2 as it bends. A protective layer 5 is provided on the outside of the wrapping layer 3, and a sheath 6 is provided on the outside of the protective layer 5. In actual use, the main body of the connection cable may bend due to the user's use. When the connection cable bends as a whole, the protective strip 4 and the protective layer 5 bend at the same time. The protective strip 4 effectively prevents the connection cable from bending and breaking. When the external force is removed, the protective layer 5 and the protective strip 4 work together to assist the connection cable in restoring the whole.
[0026] The protective strip 4 includes an elastic bending strip 41 disposed in the middle of the wire core bundle 2. The outer side of the elastic bending strip 41 is provided with several cross-shaped reinforcing ribs 42. In actual use, when the connecting wire is bent, the elastic bending strip 41 bends synchronously with the bending of the wire body, and at the same time, the cross-shaped reinforcing ribs 42 on the outer side of the elastic bending strip 41 bend synchronously with the bending of the elastic bending strip 41.
[0027] The elastic bending strip 41 is arranged parallel to the multiple wire cores 1, and the elastic bending strip 41 is placed in the middle of the multiple wire cores 1. The elastic bending strip 41 has the elasticity to return to its original position when the connecting wire is bent as a whole. When the external force disappears after the elastic bending strip 41 bends, the elastic bending strip 41 drives the connecting wire to return to its original position due to its elasticity, so that the connecting wire returns to a straight state and avoids the connecting wire from being bent for a long time, which will affect its service life.
[0028] Multiple sets of cross-shaped reinforcing ribs 42 are fixedly and vertically arranged on the outside of the elastic bending strip 41. The edges of the cross-shaped reinforcing ribs 42 extend to the intersection of multiple wire cores 1. A gap is left between two adjacent sets of cross-shaped reinforcing ribs 42 when the elastic bending strip 41 is bent. When the elastic bending strip 41 is bent, the cross-shaped reinforcing ribs 42 can effectively prevent the bending angle of the elastic bending strip 41 from being too small, so that the bending angle of the connecting line as a whole tends to be gentle. At the same time, when the elastic bending strip 41 bends to one side, the upper cross-shaped reinforcing rib 42 of the two adjacent sets of cross-shaped reinforcing ribs 42 bends downward, while the lower cross-shaped reinforcing rib 42 bends upward, so that the edges of the two sets of upper and lower adjacent cross-shaped reinforcing ribs 42 abut against each other, which can provide a resisting force opposite to that during bending, thereby preventing the connecting line as a whole from continuing to bend and protecting the connecting line.
[0029] The protective layer 5 includes a rubber layer 51 covering the outer side of the wrapping layer 3. The rubber layer 51 contains spiral threads 52 arranged in a spiral pattern following the shape of the rubber layer 51. The inner wall of the rubber layer 51 is tightly fitted to the wrapping layer 3, and the outer wall of the rubber layer 51 is tightly fitted to the inner wall of the cover 6. The spiral threads 52 are fixedly connected to the side wall of the rubber layer 51, and their diameter matches the diameter of the rubber layer 51. The spiral threads 52 are made of a metal memory material. In actual use, when the connecting wire is bent, the spiral threads 52 bend along with the rubber layer 51. When the connecting wire bends to one side, the spacing of the spiral threads 52 on the bent side shortens accordingly, while the spacing of the spiral threads 52 on the opposite side increases accordingly to accommodate the bending of the connecting wire. When the external bending force disappears, because the spiral threads 52 are spiral-shaped and made of a metal memory material, they pull the rubber layer 51 back to an upright position, preventing damage caused by prolonged bending of the connecting wire.
[0030] like Figure 3 As shown, vertical reinforcing wires 53 are provided at both ends of the connecting wire and the connector to prevent breakage at the connector. There are multiple sets of vertical reinforcing wires 53, which are arranged in an array within the side wall of the rubber layer 51 with the central center as the center. The arrangement direction of the vertical reinforcing wires 53 is consistent with the overall direction of the connecting wire. The vertical reinforcing wires 53 are fixedly connected with the spiral wires 52 to form a mesh structure. In actual use, the connection between the connecting wire and the connector is easily damaged due to frequent plugging and unplugging. By adding vertical reinforcing wires 53 to the spiral wires 52 at the connection, a mesh reinforcing wire structure is formed at the protective layer 5 at the connection between the connecting wire and the connector, which increases the life of the connecting wire at the connector and avoids damage at the connector, thereby improving the service life of the connecting wire.
