Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an anti-torsion data shielding robot cable. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine that relies on its own power and control capabilities to achieve various functions. It can accept human commands or run according to pre-programmed programs. Industrial robots generally include a mechanical arm for operation, which is connected to a cable. The main function of the cable is to transmit signals and power supply. Since the mechanical arm will continuously perform extension, movement, rotation or other complex movements during operation, the cable will often twist, and the internal shielding layer of the cable will often break, resulting in poor signal transmission or even signal transmission interruption, making the robot unable to use normally. For this reason, we propose a torsion-resistant data shielding robot cable. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a torsion-resistant data shielded robot cable. The utility model solves the problem that the robot arm will constantly perform extension, movement, rotation or other complex actions during operation, which will cause the cable to twist frequently and the internal shielding layer of the cable to break frequently, resulting in poor signal transmission or even signal transmission interruption, making the robot unable to use normally.

[0004] The utility model discloses a torsion-resistant data shielded robot cable, comprising a conductor, wherein a plurality of conductors are provided, an insulating layer is provided on the outside of the conductor, an inner shielding layer is provided on the outside of the insulating layer, a tensile center line is provided in the middle of the plurality of inner shielding layers, a tape layer is provided on the outside of the plurality of inner shielding layers, an outer shielding layer is provided on the outside of the tape layer, a flame-retardant layer is provided on the outside of the outer shielding layer, a sheath is provided on the outside of the flame-retardant layer, and a plurality of through holes arranged equidistantly are opened in the middle of the sheath.

[0005] In the above solution, a filler is filled between the tape layer and the inner shielding layer.

[0006] In the above scheme, the inner shielding layer has the same structure as the outer shielding layer, and the inner shielding layer is a semi-conductive shielding cloth and a copper wire sparsely wound layer.

[0007] In the above solution, the tensile center line is a high-strength rubber strip.

[0008] In the above solution, the flame retardant layer is a low-smoke, halogen-free and highly flame retardant glass cloth layer.

[0009] In the above solution, the wrapping layer is a transparent plastic film layer.

[0010] In the above solution, a fire-resistant coating is provided on the outside of the sheath.

[0011] The advantages and beneficial effects of the utility model are as follows: the utility model provides a torsion-resistant data shielded robot cable. When the cable is twisted, the conductors arranged in a ring outside the tensile center line press against each other, and the conductors provide torsion-resistant support force to each other, thereby improving the overall torsion resistance of the cable. The inner shielding layer is a semi-conductive shielding cloth and a copper wire sparse winding layer. The semi-conductive shielding cloth is thin and soft and has a certain toughness. The copper wire sparse winding processing shielding process can reduce the tension of the shielding layer during the torsion movement of the cable, thereby increasing the softness and torsion resistance of the cable. This type of cable has a simple structure, good shielding energy, good torsion resistance, effectively reduces the probability of cable damage, and improves the stability of cable signal transmission.

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1-2As shown, the utility model is a torsion-resistant data shielded robot cable, comprising a conductor 1, characterized in that the conductor 1 is provided with a plurality of conductors, an insulating layer 2 is provided on the outside of the conductor 1, an inner shielding layer 3 is provided on the outside of the insulating layer 2, a tensile center line 4 is provided in the middle of the plurality of inner shielding layers 3, and the setting of the tensile center line 4 effectively increases the tensile resistance of the entire cable, the conductors 1 are arranged in a matrix outside the tensile center line 4, and when the cable is twisted, the conductors 1 arranged in a ring outside the tensile center line 4 press against each other, thereby providing anti-torsion support force to each other, thereby improving the overall torsion resistance of the cable, and multiple A tape layer 6 is provided on the outside of the inner shielding layer 3, and an outer shielding layer 7 is provided on the outside of the tape layer 6. The double-layer shielding of the inner shielding layer 3 and the outer shielding layer 7 effectively improves the overall shielding performance of the cable. A flame retardant layer 8 is provided on the outside of the outer shielding layer 7. The setting of the flame retardant layer 8 effectively increases the flame retardant performance of the cable. A sheath 9 is provided on the outside of the flame retardant layer 8. A plurality of equidistantly arranged through holes 10 are provided in the middle of the sheath 9. The setting of the through holes 10 forms a buffer air cavity in the middle of the sheath 9, so that when the cable is squeezed, the pressure is buffered by the buffer air cavity, thereby effectively reducing the probability of cable damage.

[0020] A filler 5 is filled between the tape layer 6 and the inner shielding layer 3 .

[0021] The inner shielding layer 3 has the same structure as the outer shielding layer 7. The inner shielding layer 3 is a semi-conductive shielding cloth and a copper wire sparsely wound layer. The semi-conductive shielding cloth is thin and soft and has a certain toughness. The shielding process of the copper wire sparsely wound can reduce the tension on the shielding layer during the torsional movement of the cable, thereby increasing the softness and torsional resistance of the cable.

[0022] The tensile center line 4 is a high-strength rubber strip.

[0023] The flame retardant layer 8 is a low-smoke, halogen-free and highly flame-retardant glass cloth layer.

[0024] The wrapping layer 6 is a transparent plastic film layer.

[0025] The outer side of the sheath 9 is provided with a fireproof coating, and the provision of the fireproof coating effectively increases the overall fireproof performance of the cable.

[0026] Specifically, in the utility model, the setting of the tensile center line 4 effectively increases the tensile resistance of the entire cable. The conductor 1 is arranged in a matrix outside the tensile center line 4. When the cable is twisted, the conductors 1 arranged in a ring outside the tensile center line 4 press against each other, and the conductors 1 provide anti-torsion support force to each other, thereby improving the overall anti-torsion ability of the cable. The double-layer shielding of the inner shielding layer 3 and the outer shielding layer 7 effectively improves the overall shielding performance of the cable. At the same time, the inner shielding layer 3 is a semi-conductive shielding cloth and a copper wire sparse winding layer. The semi-conductive shielding cloth is thin and soft and has a certain toughness. The copper wire sparse winding processing shielding process can reduce the tension of the shielding layer during the torsional movement of the cable, thereby increasing the softness and torsion resistance of the cable. The setting of the through hole 10 forms a buffer air cavity in the middle of the sheath 9, so that when the cable is squeezed, the pressure is buffered by the buffer air cavity, effectively reducing the probability of cable damage.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
