An Industrial Ethernet Cable for Industrial Robots

technical field

The utility model relates to the technical field of Ethernet cables, in particular to an Ethernet application cable of a drag chain type industrial robot, which is mainly used for signal transmission between equipment and data systems in communication control systems and industrial automation systems.

Background technique

Industrial robots are the most typical mechatronics digital equipment with a wide range of applications. As a supporting technology for advanced manufacturing and an emerging industry in the information society, they will play an increasingly important role in future production and social development. An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom mechanical device for the industrial field. It can perform work automatically and is a machine that realizes various functions by its own power and control capabilities.

With the rapid development of information technology, especially cloud computing data needs faster and larger capacity networks to carry, and the existing Ethernet cables widely used in industrial robots can no longer meet the transmission rate of 25G/40GBASE-T The 30m distance transmission, using 25G/40GBASE-T technology, the minimum bandwidth is 300MHz.

SUMMARY OF THE INVENTION

The existing industrial Ethernet cable has low structural stability, poor flame retardant performance, poor anti-twisting and anti-extrusion ability when the cable is in use, and is prone to damage. The utility model provides an industrial Ethernet cable. An industrial Ethernet cable for a robot is provided to solve the above-mentioned problems in the background art.

In order to achieve the above purpose, the technical scheme adopted by the utility model is: an industrial Ethernet cable suitable for industrial robots, which is characterized in that: it includes an insulated wire core, a polyethylene or polypropylene material core, and a polyvinyl chloride filling and isolation. layer, aluminum foil composite tape sub-shield layer, tinned copper wire braided overall shield layer, non-woven tape, thermoplastic polyurethane sheath;

The insulated core is composed of multiple strands of tinned copper wires stranded to form an inner conductor and a layer of high-density polyethylene insulating layer extruded outside;

There is a filling core at the center of the four insulated wire cores to form a star-twisted structure, and a layer of polyvinyl chloride filling isolation layer is extruded on the outside in turn, a layer of aluminum foil composite tape is wrapped around a shielding layer, and a layer of tin plating is braided. Copper wire braided overall shielding layer, wrapped with a layer of non-woven tape, and extruded a layer of thermoplastic polyurethane sheath;

The filler core is made of polyethylene or polypropylene.

Compared with the prior art, an industrial Ethernet cable suitable for industrial robots proposed by the present utility model has the following beneficial effects:

1. The whole cable uses aluminum foil composite tape sub-shielding layer and tinned copper wire braided overall shielding layer to form a composite shielding layer, which can effectively shield the interference of low-frequency signals and high-frequency signals.

2. The star-twist structure formed by four insulated wire cores and one core-filling core is more stable than the twisted-pair structure, the relative position is fixed, and the mutual interference between the cores cancels each other out, which effectively improves the stability of the characteristic impedance of the cable.

3. The filling isolation layer structure is arranged outside the star-twist structure, so that the utility model has high stability. Even if it is twisted and dragged for a long time, the relative position of the insulated wire core can be guaranteed, which not only ensures the characteristic impedance of the wire core. It is stable, and plays a physical strengthening role, and also ensures the excellent performance of the communication after the bus cable is used for a long time.

4. The sheath is made of polyurethane material, which can protect the cable from being used in an oil-immersed environment, can effectively prevent the surface of the cable from cracking, and at the same time increase the tensile strength and physical and mechanical properties of the cable, enabling the cable to adapt to oily environments. , expanding the scope of use of the cable, greatly improving the service life of the cable.

In a word, the utility model provides an industrial Ethernet cable suitable for industrial robots with simple structure and easy installation. In use, it can not only meet the needs of signal transmission, but also have the outer protection after 3 million towline movements. Set of unbreakable features.

Detailed ways

As shown in Figures 1 and 2, an industrial Ethernet cable suitable for industrial robots includes an insulated wire core 1, a polyethylene or polypropylene material core 2, a PVC filled isolation layer 3, and an aluminum foil composite tape for separate shielding Layer 4, tinned copper wire braided overall shielding layer 5, non-woven tape 6, thermoplastic polyurethane sheath 7.

Use a cable harness machine to twist multiple tinned copper wires to form inner conductor 1-1, use a cable extruder to twist multiple tinned copper wires to form inner conductor 1-1 and extrude a layer of high-density polyethylene. The insulating layer 2 constitutes the insulated wire core 1 .

Use a cable extruder to extrude transparent polyethylene or polypropylene core filler 2 for later use.

Then use a cable twisting machine to surround the four insulated wire cores 1 with red, yellow, white and green colors around the filler core 2, and twist them into strands at a pitch of 90mm to form a star-stranded structure, and use cable extrusion outside the star-stranded structure. A layer of super-soft PVC filled isolation layer 3 is extruded out of the machine, so that the isolation layer can be firmly wrapped outside the star strand core, and the aluminum foil composite tape is wrapped around the PVC filled isolation layer 3 to separate the shielding layer. 4. Then, through the 16-spindle high-speed cable braiding machine, weave the tinned copper wire braided overall shielding layer 5 on the outside of the aluminum foil composite tape sub-shielding layer 4 to form a double-layered shielding layer. The charter machine wraps a layer of non-woven tape 6, and finally extrudes a thermoplastic polyurethane sheath 7 on the outside of the non-woven tape 6 through a cable extruder.
