Description

Technical Field

[0001] This utility model relates to the field of communication cables, and in particular to a torsion-resistant double-shielded communication cable. Background Technology

[0002] In many communication applications, such as the joint movements of robots and the rotating parts of mobile devices, communication cables need to transmit signals normally under torsion. However, existing communication cables have many problems during torsion. When subjected to torsion, the internal conductors of ordinary communication cables are prone to displacement, leading to unstable or even interrupted signal transmission. Moreover, under frequent torsion, the insulation and shielding layers of the cable are easily damaged, affecting the cable's electrical performance and service life. In addition, for some environments sensitive to electromagnetic interference, the shielding effect of existing communication cables is not ideal; a single shielding layer is insufficient to effectively isolate external electromagnetic interference, affecting signal quality. At the same time, existing communication cables also have deficiencies in abrasion resistance and tensile strength, making them prone to problems such as outer sheath damage and internal conductor breakage in dynamic use environments, further affecting the reliability and safety of the communication cables. Therefore, a torsion-resistant double-shielded communication cable is designed. Utility Model Content

The conductive wires are twisted and wrapped around the outside of the central conductive wire, the core sheath is wrapped around the inside of the conductive wires, and the conductive powder filling is filled in the gaps between the conductive wires and inside the core sheath. The conductive wires, the central conductive wire, and the conductive powder filling are all made of the same conductive material.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] A torsion-resistant double-shielded communication cable includes conductor cores 1, conductor reinforcing cores 2, insulating sheath 3, braided shielding layer 4, planar shielding layer 5, outer sheath 6, and sheath braided wire 7. Multiple sets of conductor cores 1 are provided, and these sets are twisted around the outside of the conductor reinforcing cores 2. The insulating sheath 3 covers the outside of the multiple sets of conductor cores 1 and conductor reinforcing cores 2. The braided shielding layer 4 covers the outside of the insulating sheath 3. The planar shielding layer 5 covers the outside of the braided shielding layer 4. The outer sheath 6 covers the planar shielding layers 5. The sheath braided wire 7 is braided and embedded inside the outer sheath 6.

[0015] Ceramic particle powder 12 is filled between the conductor cores 1, between the conductor core 1 and the core reinforcement core 2, and between the conductor core 1 and the insulating sheath 3. Talc powder is provided between the insulating sheath 3 and the planar shielding layer 5, in the gaps of the braided shielding layer 4, and between the planar shielding layer 5 and the outer sheath 6.

[0016] The conductor core 1 is composed of a core sheath 8, conductive wires 9, a central conductive wire 10, and conductive powder filling 11. The conductive wires 9 are twisted and wrapped around the outside of the central conductive wire 10, the core sheath 8 is wrapped around the inside of the conductive wires 9, and the conductive powder filling 11 is filled in the gaps between the conductive wires 9 and inside the core sheath 8. The conductive wires 9, the central conductive wire 10, and the conductive powder filling 11 are all made of the same conductive material.

[0017] The braided shielding layer 4 is made of tin-plated copper wire, the planar shielding layer 5 is made of aluminum foil, the core sheath 8 is made of soluble paint, the insulating sheath 3 is made of polyimide material, the outer sheath 6 is made of thermoplastic polyurethane material, and the sheath braided wire 7 is made of glass fiber material.

[0018] The working principle of this utility model is as follows: This cable has three special properties. First, it has excellent torsion resistance: the specially stranded conductive core 1, the aramid fiber reinforcing core 2, and the internally filled ceramic particles 12 enable the cable to maintain good flexibility and mechanical stability during torsion. In addition, the conductive wires 9 and the central conductive wires 10 are stranded and filled with conductive powder 11 of the same material to avoid displacement of the internal wires and ensure the stability of signal transmission.

[0019] Secondly, the double shielding effect is significant: the double shielding structure, which combines the braided shielding layer 4 and the aluminum foil shielding layer 5, has an excellent shielding effect against both low-frequency and high-frequency electromagnetic interference, ensuring the signal quality of the cable in complex electromagnetic environments.

[0020] Three key features contribute to the cable's excellent abrasion and tensile strength: a high-performance insulation layer 3, a ceramic particle filler layer 12, and a highly elastic TPU outer sheath 6 and sheath braided wire 7. These features give the cable outstanding abrasion and tensile strength, extending its service life.

[0021] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
