Abstract
The utility model relates to a high-flexibility towing-chain special-purpose cable. A neutral cable core is arranged in the middle of a polyurethane sheath layer. Six conductive cable cores are rotatably arranged with the central axis of the neutral cable core as a centre in the polyurethane sheath layer. A flexible polyurethane sheath and a PVC inner sheath wrap the neutral cable core and the conductive cable cores respectively. A polystyrene foam body is loaded between adjacent PVC inner sheaths. A first flexible rubber strip and a second flexible rubber strip are embedded in each polystyrene foam body. The special-purpose cable does not employ common elastic fillers for filling, and the polystyrene foam bodies are employed as buffering matrixes among the cable cores. In addition, the first flexible rubber strip and the second flexible rubber strip which are paired can reach the absorption buffer capability through mutual offset, stagger and extrusion of positions when the whole structure bears a distortion acting force, and the service life of the whole structure is prolonged greatly.
Description
Technical field
The utility model relates to the technical field of cable, especially a kind of high flexibility drag chain private cable.
Background technology
In known technical field, along with the development of industrial equipment, in modern manufacturing industry, at some equipment, in the structural members such as Digit Control Machine Tool, electronic equipment, hardware stamping equipment, timber stone machine process equipment, heavy-duty machinery, automatic mechanical arm, need to possess the drag chain cable of certain flexibility, because need to adapt to continuous reciprocating motion, intensity to its structure and toughness all have higher requirement, also need to adapt to the operating environments such as high-low temperature resistant variation, acid and alkali-resistance greasy dirt simultaneously.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, a kind of high flexibility drag chain private cable is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of high flexibility drag chain private cable, comprise the PVC restrictive coating setting gradually from the inside to the outside, non-woven fabrics fabric layer and urethane jacket layer, be provided with neutral cable core at the center of described urethane jacket layer, in described urethane jacket layer, and rotary setting has 6 conductive cable cores centered by the central axis of neutral cable core, be coated with respectively flexibel polyurethane sheath and PVC inner sheath in the outside of described neutral cable core and conductive cable core, between adjacent PVC inner sheath, be filled with respectively styrofoam, and all embed and have the first flexible rubber bar and the second flexible rubber bar in each styrofoam, the cross section of described the first flexible rubber bar and the second flexible rubber bar is rounded and oval respectively, and described the first flexible rubber bar arranges near the inner side of urethane jacket layer, one side of described the second flexible rubber bar is embedded in flexibel polyurethane sheath, the outside close contact of opposite side and the first flexible rubber bar.
Further, as selecting of a kind of optimal parameter, the copper conductive elements cross section in the core of conductive cable described in the utility model is less than 0.5mm
2, the copper conductive elements cross section in described neutral cable core is greater than 0.5mm
2.
Further, as a kind of concrete shielding measure, the utility model is provided with tin-coated copper stratum reticulare between described PVC inner sheath and conductive cable core.
Further, in order to play better close contact, realize the performance of flexible anti-torque song, between the first flexible rubber bar described in the utility model and the second flexible rubber bar, be adhesively fixed.
The beneficial effects of the utility model are: the utility model is simple in structure, in traditional multiple sheath formula design, do not adopt common elastic filler to fill, to reach anti-twist object, because elastic filler still can be regarded a cable in essence as, under reciprocal active force, its endurance degree can't reach higher level, in this programme, adopt styrofoam as the buffering matrix between each cable core, the first flexible rubber bar and the second flexible rubber bar of pairing can bear under distortion action power in overall structure simultaneously, by the mutual skew of position, stagger, extruding, reach the ability that absorbs buffering, make overall structure possess high flexibility, greatly improve integrally-built useful life.
Brief description of the drawings
