Description

Industrial Ethernet cable suitable for industrial robot

Technical Field

The utility model relates to an ethernet cable technical field, in particular to ethernet application cable of tow chain type industrial robot, the signal transmission between the equipment in the aspect of mainly used communication control system and the industrial automation system and the data system.

Background

The industrial robot is the most typical electromechanical integration digital equipment, has a wide application range, and plays an increasingly important role in future production and social development as a supporting technology of advanced manufacturing industry and a new industry of information-based society. An industrial robot is a multi-joint manipulator or multi-degree-of-freedom mechanical device for the industrial field, can automatically execute work, and is a machine for realizing various functions by means of self power and control capacity.

With the rapid development of information technology, particularly, cloud computing data needs faster and larger-capacity networks to be carried, and the existing Ethernet cables widely used for industrial robots cannot meet the requirement of 30m distance transmission with the transmission rate reaching 25G/40GBASE-T, and the minimum bandwidth requirement of 300MHz by using 25G/40GBASE-T technology.

Disclosure of Invention

Current industry ethernet cable structural stability is lower, and flame retardant property is relatively poor moreover, and the cable antitorque distortion and anti extrusion ability are relatively poor when using, easily appear damaging not enough, the utility model provides an industry ethernet cable suitable for industrial robot to solve the problem that exists among the above-mentioned background.

The utility model discloses a realize above-mentioned purpose, the technical scheme who takes is: an industrial ethernet cable suitable for industrial robot which characterized in that: the cable comprises an insulating cable core, a polyethylene or polypropylene filler, a polyvinyl chloride filling isolation layer, an aluminum foil composite belt sub-shielding layer, a tinned copper wire braided total shielding layer, a non-woven fabric belt and a thermoplastic polyurethane sheath;

the insulated wire core is formed by twisting a plurality of tinned copper wires to form an inner conductor and extruding a high-density polyethylene insulating layer outside the inner conductor;

a filling core is arranged at the center of each of the four insulated wire cores to form a star-twisted structure, a polyvinyl chloride filling isolation layer, an aluminum foil composite tape sub-shielding layer, a tinned copper wire braided total shielding layer, a non-woven fabric tape and a thermoplastic polyurethane sheath are sequentially extruded outside the star-twisted structure;

the filling core is made of polyethylene or polypropylene.

Compared with the prior art, the utility model provides an industrial ethernet cable suitable for industrial robot has following beneficial effect:

1. the whole cable uses the aluminum foil composite tape sub-shielding layer and the tinned copper wire braided total shielding layer to form a composite shielding layer, so that the interference of low-frequency signals and high-frequency signals can be effectively shielded.

2. The star-twisted structure formed by the four insulated wire cores and the filler core is more stable relative to the pair-twisted structure, the relative positions are fixed, the mutual interference between the wire cores is mutually counteracted, and the stability of the characteristic impedance of the cable is effectively improved.

3. The star twists the structure and sets up the isolation layer structure of packing outward, makes the utility model discloses have very high stability, even twist reverse for a long time, pull the use, also can guarantee the relative position of insulating sinle silk, both guaranteed sinle silk characteristic impedance's stability, played the physics additional strengthening again, still guaranteed bus cable's long-time back of using, the excellence of performance during the communication.

4. The sheath adopts the polyurethane material, can protect the cable to use under the environment of immersion oil, can effectually prevent the cable surface fracture, has increaseed the tensile ability and the physical and mechanical properties of cable simultaneously, can let the environment of the many oils of cable adaptation, has enlarged the application range of cable, has improved the life of cable greatly.

In a word, the utility model provides a simple structure, the industrial ethernet cable that is applicable to industrial robot of installation of being convenient for, in use not only can satisfy signal transmission's needs, has possessed the undamaged characteristics of oversheath in 300 ten thousand tow chain movements back moreover.

fig. 2 is a schematic structural view of the insulated wire core of the present invention.

Detailed Description

As shown in fig. 1 and 2, the industrial ethernet cable suitable for the industrial robot comprises an insulating wire core 1, a polyethylene or polypropylene filler core 2, a polyvinyl chloride filler isolation layer 3, an aluminum foil composite tape sub-shielding layer 4, a tinned copper wire braided total shielding layer 5, a non-woven fabric tape 6 and a thermoplastic polyurethane sheath 7.

A plurality of strands of tinned copper wires are stranded by using a cable bunching machine to form an inner conductor 1-1, and a cable extruder is used for extruding a layer of high-density polyethylene insulating layer 2 outside the inner conductor 1-1 formed by stranding the plurality of strands of tinned copper wires to form an insulating wire core 1.

A cable extruder is used to extrude a clear polyethylene or polypropylene core 2 for use.

Then, four insulation wire cores 1 with red, yellow, white and green colors are wound around a filler 2 by using a cable twisting machine, strands are twisted into a star-twisted structure according to the pitch of 90mm, a cable extruder is used outside the star-twisted structure to extrude a layer of ultra-soft polyvinyl chloride filling isolation layer 3, so that the isolation layer can be firmly wrapped outside the star-twisted wire cores, a wrapping machine is used outside the polyvinyl chloride filling isolation layer 3 to wrap an aluminum foil composite belt sub-shielding layer 4, then a 16-spindle high-speed cable braiding machine is used to weave a tinned copper wire braided total shielding layer 5 outside the aluminum foil composite belt sub-shielding layer 4 to form a double-layer shielding layer, a wrapping machine is used outside the tinned copper wire braided total shielding layer 5 to wrap a layer of non-woven fabric tape 6, and finally a thermoplastic polyurethane sheath 7 is extruded outside the non-woven fabric tape 6 by.
