Description

Technical Field

[0002] The Siemens servo system is an automatic control system that enables the output controlled quantities such as the position, orientation, and state of an object to follow any change in the input target (or given value). It positions by receiving pulse signals. Basically, when the servo motor receives a pulse, it rotates by an angle corresponding to the pulse, thereby achieving displacement. Encoder cables are required for signal transmission. Encoder cables are a type of special cable designed for connection and control, and can compile and convert signals or data into devices that can be used for communication, transmission, or storage.

[0003] Application No.: CN201921376675.0 "A Highly Flexible Encoder Cable" improves the flexibility of the encoder cable to a great extent by stranding multiple groups of cores around a filling rope, uses a non-woven tape layer with good insulation effect, and uses a braided layer to improve the tensile strength and other properties of the encoder. The encoder cable of the utility model has good flexibility, high compressive strength, good anti-twisting and anti-tensile properties, wear resistance, and a long service life, and is suitable for use in encoders.

[0004] However, during the use of the above highly flexible encoder cable, the tensile strength needs to be improved. Moreover, for multiple groups of cores stranded around the filling rope, if one group of cores catches fire, it may ignite other cores, the fire resistance needs to be improved, and multiple groups of cores may interfere with each other.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution: a highly flexible encoder cable based on a Siemens servo system, including: a tensile rope 2 for increasing the tensile performance of the cable, several groups of wire assemblies 1 are evenly arranged outside the tensile rope 2, and an outer protection assembly 4 for protecting the wire assembly 1 is arranged outside the wire assembly 1, and a filler 3 is arranged between the outer protection assembly 4 and the wire assembly 1.

[0026] The wire assembly 1 includes: several groups of conductors 12, several groups of conductors 12 are stranded outside the steel wire rope 13, and a protective sleeve 11 is arranged outside several groups of conductors 12, and a foam layer filling layer 14 is arranged between the protective sleeve 11 and the conductor 12.

[0027] Furthermore, a steel wire rope 13 is arranged in each group of wire assemblies 1. The steel wire rope 13 has strong tensile ability. When the wire assembly 1 is subjected to tension, the steel wire rope 13 can share the tension borne by the conductor 12, improving the tensile performance of the wire assembly 1, and further improving the overall tensile property of the cable; the tensile rope 2 can be made of Kevlar fiber. When the cable is subjected to tension, the tensile rope 2 can share the tension borne by each group of wire assemblies 1. With the combined use of the steel wire rope 13 and the tensile rope 2, the overall tensile property of the cable is further improved.

[0028] The protective sleeve 11 includes: an insulating layer 111, the insulating layer 111 is sleeved outside the conductor 12, and the foamed layer filling layer 14 is located between the insulating layer 111 and the conductor 12. The outside of the insulating layer 111 is provided on the inner wall of the shielding layer 112, and the outside of the shielding layer 112 is provided on the inner wall of the flame retardant layer 114. The outside of the flame retardant layer 114 is provided on the inner wall of the buffer layer 113, and the outside of the buffer layer 113 is stranded outside the tensile rope 2.

[0029] Furthermore, the foamed layer filling layer 14 enhances the protection performance of the conductor 12. The insulating layer 111 outside the conductor 12 prevents electric leakage. The shielding layer 112 outside the insulating layer 111 is used to shield external interference, thereby avoiding mutual interference between the wire assemblies 1, so as to be better applicable to the Siemens servo system. At the same time, the shielding layer 112 also plays a certain protective role for the insulating layer 111. The flame retardant layer 114 effectively improves the fire resistance of the wire assembly 1, and also prevents a group of wire assemblies 1 from catching fire and igniting other groups of wire assemblies 1. The buffer layer 113 is used to protect the flame retardant layer 114 and prevent the flame retardant layer 114 from damaging the fire protection performance.

[0030] The outer protection assembly 4 includes: a fluorescent layer 43, the inner wall of the fluorescent layer 43 is sleeved outside the outer sheath 44, and the inner wall of the outer sheath 44 is sleeved on the metal wire mesh layer 42. The inner wall of the metal wire mesh layer 42 is sleeved outside the waterproof layer 41, and the inner wall of the waterproof layer 41 is sleeved outside the buffer layer 113. The filler 3 is filled between the waterproof layer 41 and the buffer layer 113.

[0031] Furthermore, the filler 3 is a soft filling layer made of polyvinyl chloride. The soft filling layer made of polyvinyl chloride can greatly improve the flexibility of the encoder cable, enabling the cable to quickly return to its original shape after being squeezed. The waterproof layer 41 prevents the cable from getting damp inside to ensure the service life of the cable. The metal wire mesh layer 42 is used to protect the waterproof layer 41, enhance the strength of the waterproof layer 41, and prevent the waterproof layer 41 from cracking. The outer sheath 44 is used to protect all the components inside it as a whole. The fluorescent layer 43 makes the cable more conspicuous and prevents people from tripping over the cable.

[0032] Working principle: A steel wire rope 13 is provided in each wire assembly 1. The steel wire rope 13 has strong tensile capacity. When the wire assembly 1 is subjected to tension, the steel wire rope 13 can share the tension borne by the conductor 12, improving the tensile performance of the wire assembly 1, and thus enhancing the overall tensile property of the cable. The tensile rope 2 can be made of Kevlar fiber. When the cable is subjected to tension, the tensile rope 2 can share the tension borne by each wire assembly 1. With the combined use of the steel wire rope 13 and the tensile rope 2, the overall tensile property of the cable is further improved.

[0033] The foaming layer filling layer 14 enhances the protection performance of the conductor 12. The insulating layer 111 outside the conductor 12 prevents electric leakage. The shielding layer 112 outside the insulating layer 111 is used to shield external interference, thereby avoiding mutual interference between the wire assemblies 1. At the same time, the shielding layer 112 also plays a certain protective role for the insulating layer 111. The flame-retardant layer 114 effectively improves the fire resistance of the wire assembly 1, and also prevents a group of wire assemblies 1 from catching fire and igniting other groups of wire assemblies 1. The buffer layer 113 is used to protect the flame-retardant layer 114 and prevent the flame-retardant layer 114 from damaging the fire protection performance.

[0034] The filler 3 is a soft filling layer made of polyvinyl chloride. The soft filling layer made of polyvinyl chloride can greatly improve the flexibility of the encoder cable, enabling the cable to quickly return to its original state after being squeezed. The waterproof layer 41 prevents the cable from getting damp inside to ensure the service life of the cable. The metal wire mesh layer 42 is used to protect the waterproof layer 41, enhance the strength of the waterproof layer 41, and prevent the waterproof layer 41 from cracking. The outer sheath 44 is used to protect all the components inside it as a whole. The fluorescent layer 43 makes the cable more eye-catching and prevents people from tripping over the cable.
