Layer；
The gauge of wire is in 0.08mm~0.12mm, and the thickness of the layers of copper is in 0.05mm~0.1mm；
A gap, the thickness in the gap are left between the polyvinyl chloride insulation sheath and the stainless steel corrugated flexible hose
In 0.2mm~0.4mm.
The utility model is overall by adding cable provided with the steel wire core that at least two steel wires are made by twisting in cable core
Structural strength, while improving ability resistant to bending.
Because alternating current has Kelvin effect when in use, when electric current passes through cable core conductor, the thin of conductor appearance is concentrated on
Layer, closer to conductive surface, current density is bigger, so this design is conductive with layers of copper, bending resistance is increased using steel wire core,
In the case where not influenceing original cable size, conductor resistance excessively, the bending resistance of cable is considerably increased, improves and uses
Life-span.
Sheath leaves gap with flexible pipe part, is easily installed, or, adhesive waterproof tape can be wound outside sheath.
The polyvinyl chloride insulation sheath includes an internal layer, an outer layer, provided with one layer of glass between the internal layer, the outer layer
Glass fiber cloth.Using the intensity of commercially available glass fabric increase cable, anti-shearing force, glass fabric is prevented with certain
Water, flameproof effect.Cable core is located in internal layer.
The internal layer thickness is between 2mm~3mm, and the outer layer thickness is between 3mm~5mm.
The outer surface of the internal layer is provided with least two annular projections, and the inner surface of the outer layer is provided with and the ring
The groove that shape projection matches；
Being spaced between 30mm~50mm between the two neighboring annular projection, the height of the annular projection exists
1mm~1.5mm.Using the matching of annular projection, groove, strengthen the bonding strength of internal layer and outer layer, while glass fabric is embedding
Enter to the gap between annular projection and groove, improve the bonding strength of internal layer, outer layer and glass fabric.
In order to improve internal layer, outer layer and the bonding strength of glass fabric, the surface of the annular projection, the groove
Inwall on to be equipped with needle-like raised.To increase frictional force, adhesion effect is improved.
The outer surface of the outer layer is raised provided with least two, and projection described at least two is evenly distributed on the outer layer
Outer surface on, raised height is in 0.4mm~0.6mm described at least two.To increase outer layer and stainless steel corrugated flexible hose
Between frictional force.
Brief description of the drawings
Fig. 1 is part-structure schematic cross-section of the present utility model.
