Abstract

A kind of power cable, it comprises the bellows (12) strengthened from supporting, fiber being coupled to metallic conductor (11), the thickness of the bellows (12) that wherein said fiber is strengthened reduces gradually along the length of described cable, also comprises a kind of jumper cable be made up of above-mentioned power cable.Technique effect of the present utility model is: compared to the prior art, the utility model adopts bellows, this cable is effective especially when being used as the jumper cable of link, because this cable can bend on Three-Dimensional Dynamic ground, and it is rotatable with the motion adapting to the link in use, and still keep from supporting, even when supporting very large conduction ribbon.

Description

Power cable and the jumper cable be made up of it
Technical field
The utility model relates to power cable.
Background technology
Present cable can not be accomplished to fix its shape when not having external force, again can according to torsion change shape when external torsion is larger, the such as interconnective jumper cable in compartment, and prior art cannot be accomplished, the cable in junction, compartment is in maintenance supporting certainly.
Utility model content
The purpose of this utility model is to provide a kind of power cable being provided with bellows, and it can bend on Three-Dimensional Dynamic ground, and rotatable with the motion adapting to the link in use, and still keeps from supporting.
The technical solution of the utility model is specially:
A kind of power cable, it comprises the bellows strengthened from supporting, fiber being coupled to metallic conductor, and the thickness of the bellows that wherein said fiber is strengthened reduces gradually along the length of described cable.
Power cable as described in claim 1, the thickness of the bellows that wherein said fiber is strengthened near a part of cable be crimped than thicker near a part of cable be not crimped.
A kind of jumper cable, it is made up of such as power cable in any one of the preceding claims wherein.
Technique effect of the present utility model is: compared to the prior art, the utility model adopts bellows, this cable is effective especially when being used as the jumper cable of link, because this cable can bend on Three-Dimensional Dynamic ground, and it is rotatable with the motion adapting to the link in use, and still keep from supporting, even when supporting very large conduction ribbon.
Accompanying drawing explanation
Fig. 1 is the sectional view of cable.
Fig. 2 is the 3-D view of jumper cable.
Fig. 3 is the 3-D view of jumper cable distortion.
Embodiment
Referring to Fig. 1, the sectional view through part jumper cable illustrate supported by bellows 12 conduction, tin-coated copper ribbon 11, all wrap in heat-shrinkable tube 13,15, and sealant 14 between which makes cable not to be subject to weather effect.In use, bellows by the weight of self and ribbon of supporting, need this from supporting but ribbon self does not have enough rigidity carries out in the application of supporting, this be special easily.
Bellows 12 is tapers, provides larger rigidity/supporting thus and provide less rigidity/supporting in its thinnest end in its thickest end.The position that this tapering contributes to being crimped at cable ribbon especially provides larger rigidity/supporting, and is not provided less rigidity/supporting (and having more large inner rigidity) by the position crimped like this at cable.
This tapering is also applicable to from supporting cable, from supporting cable at one end securely anchoring and therefore supporting whole cable weight end than the self-support end of the cable do not play supporting role needs more rigidity/supportings.
See Fig. 2 and Fig. 3, a kind of jumper cable by above-mentioned cables manufacturing.

Claims (3)

1. a power cable, it comprises the bellows (12) strengthened from supporting, fiber being coupled to metallic conductor (11), and the thickness of the bellows (12) that wherein said fiber is strengthened reduces gradually along the length of described cable.
2. the power cable as described in claim 1, the thickness of the bellows (12) that wherein said fiber is strengthened near a part of cable be crimped than thicker near a part of cable be not crimped.
3. a jumper cable, it is made up of such as power cable in any one of the preceding claims wherein.
