Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a high-strength spring charging cable includes a cable tube 10, and an insulating sheath 11 disposed inside the cable tube 10

Wherein, the inside of insulating sheath 11 is run through there is conductor 12, and the inside of cable pipe 10 still is provided with filler wire 13, provides the buffer structure to the deformation of filling layer 105 through the filler wire 13 that sets up, shifts the friction between the filling layer 105 to the friction to filler wire 13 for the damage that filling layer 105 can receive originally shifts to filler wire 13, with this protection effect that provides.

Wherein, the filling wire 13 is oval, the quantity of the filling wire 13 is consistent with the quantity of the conductors 12, the filling wire 13 is uniformly arranged between two adjacent conductors 12, the material of the filling wire 13 is soft rubber material, the material of the filling layer 105 is reticular high-strength filling rope, the filling wire 13 is oval, the uniform distribution is between the conductors, because the filling layer 105 generally adopts reticular rigid strength filling rope, therefore, in practical application, because the charging cable is in bending and stretching state for a long time, the mutual friction between the filling ropes appears, the damage of the filling rope is caused, the service life of the filling layer 105 is reduced, and the filling wire 13 is arranged, because the filling wire 13 is soft material, when in use, a soft buffer structure is provided, the friction between the inner filling layer 105 is avoided, when extrusion deformation occurs, because the material of the filling wire 13 is soft, most of the deformation is generated at the filling wire 13, because the structure is set to be oval, the deformation can be more easily generated at the filling wire 13, the support of the filling wire 13 is assisted, not only the deformation position is at the filling wire 13, but also the damage of the filling wire 105 can be avoided.

The cable tube 10 comprises an outer tube wall 101, an outer sheath 102, a protective layer 103, an inner sheath 104 and a filling layer 105, and the cable tube 10 is arranged from the outermost layer to the inner side in the following sequence: the outer pipe wall 101, the outer sheath 102, the protective layer 103, the inner sheath 104 and the filling layer 105, the outer pipe wall 101 and the protective layer 103 provide soft and elastic protective layers, the outer sheath 102 and the inner sheath 104 provide hard net-shaped materials for supporting, and the situation that the materials are too soft and easy to damage is avoided.

Wherein, the inside of filling layer 105 is provided with the notch, and filler wire 13 and insulating sheath 11 all set up inside the notch of filling layer 105.

The insulating sheath 11 is made of a low-smoke halogen-free flame-retardant polyolefin material, the conductor 12 is made of an annealed six-class soft conductor, the outer tube wall 101 and the protective layer 103 are made of thermoplastic elastomer materials, and the outer sheath 102 and the inner sheath 104 are both net-shaped wires.

The working principle is as follows: when using, the cable body can constantly be in and pull, deformation operations such as bending, make originally should be netted filling layer 105 and begin to extrude to the inboard, owing to be provided with filling wire 13, again because filling wire 13 sets up to oval, make the main extrusion position of inside extruded filling layer 105 be filling wire 13's position, and because filling wire 13 is soft rubber, make filling layer 105 though can extrude filling wire 13's position, but can provide the arc buffering, guarantee that filling layer 105 can not receive too much damage, and prolonged service life, be provided with oversheath 102 and inner sheath 104 outside in addition and provide double-deck shielding structure, avoid the influence of static to the cable body, to current structure, the structure is more outstanding.
