Technical Field

[0001] The utility model belongs to the technical field of speaker cables, and particularly relates to a tensile and anti-interference speaker cable. Background Art

[0002] Speaker cable, also known as audio cable, is a cable used to connect power amplifiers and speakers. It is an important medium for transmitting audio signals from audio equipment to speakers. It is an important component in electronic devices for transmitting audio signals and can be used in speakers and car audio equipment.

[0003] In the prior art, speaker cables are prone to mutual signal interference during signal transmission, resulting in a decrease in signal transmission quality. Interference from external signals can also affect the transmission effect. In addition, speaker cables are often dragged during use, resulting in damage to the cable body, poor tensile strength, and easy breakage, resulting in a short service life. Therefore, an improvement is now made to a speaker cable. Utility Model Content

[0006] Compared with the prior art, the beneficial effects of the utility model are: by setting two independent shielding layers, it can prevent the wires inside the speaker cable from interfering with each other, and can also prevent external wires from interfering with the speaker cable, thereby improving the overall anti-interference ability of the speaker cable; by setting a tensile wire between the two wires, it can avoid the wear of the two wires caused by mutual friction, and can also improve the overall tensile performance of the speaker cable, and the insulating elastomer can also cope with the deformation that may occur when the speaker cable is bent; the outer sheath can improve the wear resistance of the speaker cable, and the V-shaped groove can facilitate personnel to peel off the outer sheath.

[0007] As a further improvement of the utility model, the conductor is made of a plurality of strands of silver-plated copper wires twisted together.

[0016] like Figure 1 and 2 As shown, a tensile and anti-interference type speaker cable comprises two conductors 1 arranged in parallel with each other, and the two conductors 1 are symmetrically distributed on both sides of the tensile cable 2. Specifically, the two conductors 1 are respectively a positive conductor 1 and a negative conductor 1; the tensile cable 2 comprises a reinforcing rib 201 and an insulating elastomer 202 coated on the outside of the reinforcing rib 201; the conductor 1 comprises a conductor 3, an insulating layer 4, a shielding layer 5 and a water-blocking layer 6 arranged in sequence from the inside to the outside, preferably, the conductor 3 is made of a plurality of strands of silver-plated copper wires, the insulating layer 4 is made of a cross-linked polyethylene material, the shielding layer 5 is made of a graphene material, and the water-blocking layer 6 is coated with a plurality of layers of waterproof yarn; an outer sheath 7 is extruded on the outer side of the tensile cable 2 and the two conductors 1, and a V-shaped groove 701 is opened on the outer sheath 7 corresponding to both sides of the tensile cable 2; the cross section of the insulating elastomer 202 is designed to be an elliptical structure, and the cross section of the outer sheath 7 is designed to be an 8-shaped structure, so that the speaker cable structure is compact and suitable for narrow and long use space.

[0017] The advantages of the utility model are: the conductor 3 made of silver-plated copper wire has better conductivity than the commonly used pure copper conductor 3, so that the speaker cable has better conduction quality and higher transmission efficiency; the cross-linked modified polyethylene can greatly improve its performance, not only significantly improving the mechanical and electrical properties of polyethylene, but also improving the temperature resistance level, thereby improving the heat resistance of the speaker cable; graphene is a honeycomb lattice structure composed of carbon atoms, and the structure itself has excellent shielding ability for high-frequency interference signals. Compared with the metal shielding layer 5 of the same thickness, the graphene shielding layer 5 has higher shielding ability, and the structure of graphene is very stable. When external force is applied to the graphene, it will not destroy its structural arrangement, which can further improve the tensile strength of the speaker cable.
