[0002] Industrial robot wiring harness is a wiring harness specially used to connect various sensors, electronic components, controllers and other electronic devices in industrial robots.

[0003] It includes power lines, robot joint lines, robot sensor lines, robot controller lines, etc., which are responsible for transmitting signals and electricity and protecting the wires from damage.

[0025] In the description of the present invention, "plurality" means two or more than two, unless otherwise clearly and specifically defined.

[0026] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The utility model greatly improves the overall wear resistance of the wiring harness by setting the wear-resistant layer, protective layer, wear-resistant block and reinforcing ribs; the overall high temperature resistance of the wiring harness is improved by setting the internal protective layer, heat insulation layer, heat insulation gasket and heat insulation film. Figure 1 , Figure 2 , Figure 3 and Figure 4 , comprising an internal component 100 and an external component 200.

[0028] The external component 100 includes a wear-resistant layer 110. In order to improve the wear-resistant effect, the circumferential inner wall of the wear-resistant layer 110 is connected with a protective layer 120 by bonding. In order to make the wear-resistant effect of the wear-resistant morning light 110 better, the circumferential outer wall of the wear-resistant layer 110 is left with a wear-resistant block 130 by integral molding. In order to improve the wear resistance and support of the protective layer 120, the side wall of the protective layer 120 is connected with a reinforcing rib 140 by embedding.

[0029] The internal component 200 includes an internal protective layer 210 connected to the circumferential inner wall of the protective layer 120 by gluing. In order to improve the heat resistance of the wiring harness, the circumferential inner wall of the internal protective layer 210 is connected to the thermal insulation layer 220 by gluing. In order to make the internal protective layer 210 have a good thermal insulation effect, the internal protective layer 210 includes a thermal insulation gasket 250 connected to the circumferential outer wall of the thermal insulation layer 220 by embedding. The circumferential outer wall of the thermal insulation gasket 210 is connected to the thermal insulation film 260 by gluing. In order to prevent the battery cells 230 from sticking to each other, the circumferential inner wall of the thermal insulation layer 220 is connected to the battery cells 230 by embedding, and the circumferential outer wall of the battery cells 230 is connected to the filler 240 by embedding.

[0030] Working principle: When the device encounters extrusion or friction, the wear-resistant block 130 will first provide protection, resisting friction while playing a certain buffering role. After the wear-resistant block 130 is worn out, the wear-resistant layer 110 will provide wear-resistant protection for the wiring harness. When encountering increased friction, the internal protective layer 120 will provide further protection. The reinforcing ribs 140 in the protective layer 120 support the wiring harness while being wear-resistant to prevent impact from invading the interior of the wiring harness. When encountering a high-temperature working environment, the thermal insulation film 260 and the thermal insulation gasket 250 will cooperate with each other to prevent high temperature or fire from invading the battery cell 230. The outer periphery of the battery cell 230 is also wrapped with a thermal insulation layer 220 to provide more comprehensive protection.

[0031] Furthermore, in order to ensure the wear-resistant effect of the wear-resistant layer 110 and the wear-resistant block 130, specifically, the material of the wear-resistant layer 110 and the wear-resistant block 130 is silicone rubber, and the thickness of the wear-resistant layer 110 is 2.5 mm.

[0032] Next, in order to make the protective layer 120 also have good wear resistance and provide certain support for the wiring harness as a whole, specifically, the material of the protective layer 120 is nitrile rubber, the material of the reinforcing ribs 140 is thermoplastic polyurethane, and the side walls of the protective layer 120 are embedded with multiple reinforcing ribs 140, and the multiple reinforcing ribs 140 form a ring to protect the wiring harness.

[0033] It is worth noting that in order to make the internal protective layer 210 more resistant to high temperatures, specifically, the internal protective layer 210 is composed of a plurality of thermal insulation gaskets 250 connected in combination with a thermal insulation film 260 that is pasted and wrapped, and the thermal insulation gaskets 250 and the thermal insulation film 260 are made of silicone material.

[0034] In addition, in order to make the heat insulation layer 220 heat-resistant and protect the inside of the wiring harness, specifically, the heat insulation layer 220 is made of EPDM rubber material, and the thickness of the heat insulation layer 220 is 1.5 mm.

[0035] Finally, in order to improve the stability of the wear-resistant block 130 during friction and to make the protective effect of the wear-resistant block 130 better, specifically, the wear-resistant block 130 adopts a design of narrow upper and lower style to reduce the possibility of breakage of the wear-resistant block 130 during friction. The circumferential outer currency of the wear-resistant layer 110 is integrally formed to leave multiple wear-resistant blocks 130, and the multiple wear-resistant blocks 130 form a ring on the wear-resistant layer 110 to provide more comprehensive protection.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
