Description

Technical Field

[0001] This utility model relates to the technical field of cables, and in particular to a high-speed data transmission cable. Background Technology

[0002] With the development of industry, more and more automated industrial equipment requires high-speed data transmission cables. Furthermore, existing automated industrial equipment places higher demands on the transmission rate and mechanical reliability of high-speed data transmission cables. Not only is a fast transmission rate required, but the data transmission cable is also required to be resistant to damage and breakage when moving with mechanical parts. Structurally, data transmission cables include conductor cores, insulating dielectric layers, shielding layers, and sheaths. However, when existing data transmission cables move with mechanical parts, they bend and oscillate. Under long-term bending and oscillation, the conductor cores are prone to breakage, and the shielding layer is also prone to loosening and damage. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a high-speed data transmission cable that is less prone to breakage or damage when following the long-term movement of mechanical parts, thus improving its service life.

[0004] A high-speed data transmission cable according to an embodiment of the present invention includes: a transmission line comprising a plurality of core wires, each core wire comprising a first conductor and a first nylon filament, the first conductor and the first nylon filament being twisted together, the first conductor being made of hard-state tin-plated copper; a wound shielding layer comprising a plurality of winding wires, the plurality of winding wires being wound around the transmission line, wherein 50% of the winding wires are wound in the forward direction and 50% of the winding wires are wound in the reverse direction; and a sheath fitted onto the outer surface of the wound shielding layer, the sheath being made of silicone material.

[0005] A high-speed data transmission cable according to an embodiment of the present invention has at least the following beneficial effects:

[0006] 1. This utility model, by setting a core wire, has a first conductor and a first nylon filament. The first conductor is made of hard-plated copper material. The hard-plated copper material is not annealed. The yield strength of the hard-plated copper conductor is significantly higher than that of the annealed copper conductor. In addition, the first nylon filament has good flexibility. The core wire is formed by twisting the hard-plated copper conductor and the nylon filament. The core wire is both soft and hard, and can be bent and swing freely. Furthermore, it makes the core wire less prone to breakage when the high-speed data cable follows the long-term movement of mechanical parts, thus improving the bending and swinging life of the high-speed data cable.

[0007] 2. This utility model, by setting a winding shielding layer, which includes multiple winding lines, with 50% of the winding lines wound in the forward direction and 50% of the winding lines wound in the reverse direction, ensures that the winding shielding layer is not easy to loosen and can tightly wrap the transmission line. Therefore, the winding shielding layer is not easy to loosen or be damaged when the high-speed transmission data cable is bent and swung for a long time, thus improving the service life of the high-speed transmission data cable.

[0008] 3. By setting a protective sleeve made of silicone, this utility model can further protect the wound shielding layer, making it less likely to loosen. In addition, the silicone sleeve has a low elastic modulus, making it more flexible and with a high deformation recovery rate after long-term bending. When the high-speed data transmission cable is bent and swayed, it can avoid damage to the wound shielding layer caused by the creep of the sleeve.

[0009] According to an embodiment of the present invention, a high-speed data transmission cable is provided in which the plurality of core wires are untwisted and twisted together.

[0010] A high-speed data transmission cable according to an embodiment of the present invention further includes a first filler wire, which is located between the plurality of core wires, and the plurality of core wires are twisted around the first filler wire.

[0012] According to an embodiment of the present invention, a high-speed data transmission cable is provided, wherein the transmission line further includes a plurality of ground wires, the ground wires being arranged between two adjacent core wires.

[0013] According to an embodiment of the present invention, a high-speed data transmission cable further includes a plurality of second filler wires, which form a gap between the ground wire and the core wire.

[0014] A high-speed data transmission cable according to an embodiment of the present invention further includes a braided layer, which is disposed on the outer surface of the sheath.

[0025] A high-speed data transmission cable according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] Reference Figure 1 The present invention aims to provide an embodiment of a high-speed data transmission cable.

[0027] A high-speed data transmission cable according to an embodiment of this utility model, referring to... Figure 1 and Figure 2 The transmission line includes multiple core wires 100, each core wire 100 including a first conductor 110 and a first nylon filament 120, which are twisted together. The first conductor 110 is made of hard-state tin-plated copper.

[0028] It is understood that in this embodiment, by setting the core wire 100, the core wire 100 has a first conductor 110 and a first nylon filament 120. The first conductor 110 is made of hard-plated copper material. The hard-plated copper material is not annealed. The yield strength of the hard-plated copper conductor is significantly higher than that of the annealed copper conductor. In addition, the first nylon filament 120 has good flexibility. The core wire 100 is formed by twisting the hard-plated copper conductor and the nylon filament. The core wire 100 is both soft and hard, and can be bent and swung freely. Furthermore, it makes the core wire 100 less likely to break when the high-speed data cable follows the long-term movement of mechanical parts, thus improving the bending and swaying life of the high-speed data cable.

[0029] A high-speed data transmission cable according to an embodiment of the present invention further includes a wound shielding layer 130, which includes a plurality of winding wires that wrap around the transmission line. Among the plurality of winding wires, 50% of the winding wires are wound in the forward direction and 50% of the winding wires are wound in the reverse direction.

[0030] It is understood that in this embodiment, by setting a winding shielding layer 130, which includes multiple winding lines, 50% of the winding lines are wound in the forward direction and 50% of the winding lines are wound in the reverse direction. The forward and reverse winding of the shielding layer 130 makes it less likely to loosen and can tightly wind the transmission line. Therefore, the winding shielding layer 130 is less likely to loosen and be damaged when the high-speed transmission data cable is bent and swung for a long time, thus improving the service life of the high-speed transmission data cable.

[0031] It should be noted that the winding wire of the winding shielding layer 130 is made of tin-plated copper material, and the winding shielding layer 130 can be used as a shielding layer.

[0032] A high-speed data transmission cable according to an embodiment of the present invention also includes a sheath 140, which is fitted onto the outer surface of the wound shielding layer 130, and the sheath 140 is made of silicone material.

[0033] It is understood that by setting a sheath 140 in this embodiment, the sheath 140 is made of silicone material. The sheath 140 can further protect the wound shielding layer 130, making the wound shielding layer 130 less likely to loosen. In addition, the silicone sheath 140 has a low elastic modulus, making the sheath 140 more flexible. The sheath 140 has a high deformation recovery rate after long-term bending. When the high-speed transmission data cable is bent and swung, it can avoid the damage to the wound shielding layer 130 caused by the creep of the sheath 140.

[0034] In some embodiments of this utility model, multiple core wires 100 are untwisted and twisted together.

[0035] It is understood that this embodiment uses a de-twisting process to strand multiple core wires 100, which can eliminate residual torque inside the core wires 100, so that each core wire 100 is subjected to uniform force when the cable is dynamically bent, avoiding the problem of core breakage caused by stress concentration at a single point.

[0036] In a further embodiment of the present invention, a first filler wire 150 is also included. The first filler wire 150 is located between a plurality of core wires 100, and the plurality of core wires 100 are twisted together with the first filler wire 150 as the center.

[0037] It is understood that in this embodiment, the first filler wire 150 is used as the stranding center to fix the relative position between multiple core wires 100, prevent the core wires 100 from misaligning and rubbing during dynamic bending, and reduce the risk of wear on the insulation layer 160. It should be noted that the material of the first filler wire 150 can be nylon filament.

[0038] In some embodiments of this utility model, the core wire 100 further includes an insulation layer 160, which wraps the stranded first conductor 110 and the first nylon filament 120. The insulation layer 160 is made of FEP material.

[0039] It is understood that FEP is used as the insulation layer 160 in this embodiment. FEP is also known as Teflon. The dielectric constant of FEP material is 2.1, which is lower than that of conventional PE (2.3) or PVC (3.0), thus reducing the signal transmission loss of the core wire 100.

[0040] In addition, FEP has strong adhesion to nylon filaments, and the insulation layer 160 deforms synchronously with the conductor when bent, avoiding delamination problems.

[0041] In some embodiments of the present invention, the transmission line further includes a plurality of ground wires 170, which are arranged between two adjacent core wires 100.

[0042] It is understandable that ground wire 170 serves as a local ground between the wrapped shielding layer 130 and the signal line.

[0043] In some embodiments of this utility model, a plurality of second filler lines 180 are also included, which form a gap between the ground line 170 and the core line 100.

[0044] Understandably, the second filler wire 180 fills the gap between the ground wire 170 and the core wire 100 to prevent the core wire 100 and the ground wire 170 from undergoing plastic deformation due to the gap when the cable is bent.

[0045] In some embodiments of this utility model, a braided layer 190 is also included, which is disposed on the outer surface of the sheath 140.

[0046] Understandably, the braided layer 190 protects the sheath 140, making the cable suitable for industrial equipment in environments with frequent friction.

[0047] In some embodiments of this utility model, the braided layer 190 is made of polyester fiber material.

[0048] Understandably, using polyester fiber as the braid layer 190 results in a low coefficient of friction on the surface of the braid layer 190, making it less prone to wear. In addition, the density of polyester fiber can reduce the weight of the cable, making it suitable for high-speed moving mechanical parts.

[0049] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, 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.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 the present utility model.
