Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a pulling and scratch-resistant elastic soft cable. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. It is made of one or more mutually insulated conductors and an outer insulating protective layer. It transmits electricity or information from one place to another.

[0003] At present, in daily applications and industrial equipment, especially in the fields of intelligent transformation, intelligent manipulators, robots, etc., there is an increasing demand for the resilience of wires and cables. The connection cables in the prior art have poor resilience, are not easy to operate under working conditions with high cable elasticity requirements, and have poor performance. At the same time, this type of cable may be scratched during mobile laying or use. The surface of the existing cables is prone to scratches, which not only affects the appearance but also easily cracks and affect the performance. Therefore, there is an urgent need for a tensile and scratch-resistant elastic soft cable to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and propose a tensile and scratch-resistant elastic soft cable. The advantages are that the cable has good resilience and tensile strength, meeting the elasticity requirements in use, and the sheath has good scratch resistance. When scratched by stones, angle irons and other sharp corners, the sheath surface will not be damaged or scratched.

[0013] Through the above technical solution: the resilient core is made of a composite of elastic steel wire rope and silicone rubber insulating material. The elastic steel wire rope can improve the tensile strength of the cable, and its high elasticity can make the cable have better autonomous resilience.

[0014] The utility model is further configured that the material of the filling layer is aramid fiber rope.

[0018] The utility model is further configured that the outside of the reinforcement layer is wrapped with a mica tape layer, the outside of the mica tape layer is provided with a flame retardant layer, and the outside of the flame retardant layer is provided with an armor layer.

[0037] Specifically, the material of the conductor 4 is annealed copper conductor material, and the fifth type of annealed copper conductor material is adopted, which has good softness.

[0038] Specifically, the insulating layer 5 is made of silicone rubber insulating material, which is extruded on the outside of the conductor 4. The average thickness of the insulating layer 5 is 0.5 mm to 1.7 mm. The silicone rubber insulating material has excellent electrical insulation performance, certain elasticity, and good oil resistance, aging resistance and other properties.

[0039] Specifically, the components of the resilient core 6 include elastic steel wire rope and silicone rubber insulating material. The resilient core 6 is arranged at the center of the cable. The elastic steel wire rope is formed by twisting multiple strands of fine steel wires. The outer diameter of the elastic steel wire rope is 0.8mm~2.5mm. The silicone rubber insulating material is extruded on the outside of the fine steel wire. The resilient core 6 is made of a composite of elastic steel wire rope and silicone rubber insulating material. The elastic steel wire rope can improve the tensile strength of the cable. At the same time, its high elasticity can make the cable have better autonomous resilience, avoiding cable damage due to passive bending during reciprocating bending. The extruded silicone rubber insulation is to avoid electrical breakdown caused by friction between the steel wire rope and the insulating core during bending.

[0040] Specifically, the filling layer 3 is made of aramid fiber rope. The aramid fiber itself is relatively soft, has extremely high strength and is light in weight. It is filled around the wire core, which greatly enhances the strength of the cable and ensures the integrity of the cable when the cable is bent or stretched back and forth.

[0041] Specifically, the material of the reinforcement layer 2 is a nylon braided layer with a braiding density of not less than 80%. The material of the outer sheath 1 is a TPE sheath material.

When scratched by stones, angle irons and other sharp corners, the surface of the outer sheath 1 will not be damaged or scratched. The rebound core 6 is made of elastic steel wire rope and silicone rubber insulating material. The elastic steel wire rope can improve the tensile strength of the cable. At the same time, its high elasticity can make the cable have better autonomous resilience, avoiding cable damage due to passive bending during reciprocating bending. The extruded silicone rubber insulation is to avoid electrical breakdown caused by friction between the steel wire rope and the insulating core during bending. At the same time, the filling layer 3 is made of aramid fiber rope. The aramid fiber itself is relatively soft, has extremely high strength and is light in weight. It is filled around the core, which greatly enhances the strength of the cable. The integrity of the cable is ensured when the cable is bent or stretched back and forth. The reinforcement layer 2 is woven with nylon threads. Nylon threads are softer, more elastic and have excellent mechanical properties. The woven structure can better fit the flat cable core, effectively improve the overall toughness and mechanical properties of the flat cable, and ensure the stability of the overall structure of the flat cable during reciprocating bending, thereby improving the mechanical properties of the cable. At the same time, a polyester tape is wrapped between the cable core and the braided layer to reduce the friction between the cable core and the reinforcement layer, and to protect the insulation from being worn or torn by the cable core during bending and reciprocating motion. At the same time, in order to improve the scratch resistance of the cable, the outer sheath 1 adopts a TPE sheath. TPE has a comfortable texture and a smooth feel.
