Detailed Description

The utility model relates to a cable containing an insulating steel core 1 and an aluminum alloy stranded wire 2, which comprises the steel core 1 arranged at the center position in the cable for transmitting power and the aluminum alloy stranded wire 2 wound on the surface of the steel core 1 for assisting in transmitting power, wherein a buffer component with an impact resistance effect is arranged outside the aluminum alloy stranded wire 2, as shown in figures 1-3.

As shown in fig. 1 to 3, the buffer assembly includes an inner sheath 3 provided outside the aluminum alloy stranded wire 2 for fixing and insulating, and an outer sheath 4 provided outside the inner sheath 3 for supporting.

As shown in fig. 1-3, the outer sheath 4 is uniformly provided with contacts 5 which are concave and convex in the circumferential direction and are used for absorbing impact energy after the cable deforms when bearing external force impact.

As shown in fig. 1-3, a plurality of groups of connecting pieces 6 for connecting the outer sheath 4 and the inner sheath 3 are uniformly arranged between the outer sheath and the inner sheath, and the connecting pieces 6 are in a lightning-like shape and used for absorbing impact energy after the cable deforms when bearing external force impact.

As shown in fig. 1 to 3, the outer sheath 4 is provided with a shielding sheath 7 for shielding interference.

As shown in fig. 1 to 3, the shielding sheath 7 is provided with an insulating sheath 8 for physical insulation on the outside.

As shown in fig. 1-3, the exterior of the insulating sheath 8 is provided with an indicator strip 9 that can be used to indicate whether the cable is coiled.

When a user uses the cable manufactured by the utility model, the buffer component capable of absorbing the impact from external force is arranged outside the steel core 1 coated with the aluminum alloy stranded wire 2, when the cable is impacted by external force, the shielding sheath 7 and the insulating sheath 8 are made of softer materials and can generate benign deformation, then the external force can act on the upper part of the outer sheath 4 through the shielding sheath 7 and the insulating sheath 8, the contact 5 is uniformly arranged in the circumferential direction of the outer sheath 4, then the outer sheath 4 can generate certain deformation to absorb the energy generated by the impact, and then the energy generated by the impact is further absorbed through the deformation of the connecting piece 6, so that the impact force from the outside is resisted to the maximum extent, the steel core 1 and the aluminum alloy stranded wire 2 in the cable are protected from being damaged, the power transmission effect is ensured, and the design of the indicating strip 9 can avoid the situation that the cable is excessively curled in the using process and cannot be found by a user in time, but damage the steel core 1 or the aluminum alloy stranded wire 2; the surface of the steel core 1 is covered with the aluminum alloy stranded wires 2 arranged around the surface of the steel core, so that the wire effect of the cable can be greatly improved, and the loss of electric energy is reduced.

It is to be understood that the present invention has been described with reference to certain embodiments and that various changes in form and details may be made therein by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof.
