Description

Technical Field

[0001] This utility model belongs to the field of data transmission equipment technology, specifically a highly protected industrial data transmission harness. Background Technology

[0002] Industrial wire harnesses, acting as the neural network of industrial equipment, undertake the tasks of power, signal, and data transmission, and directly affect the reliability and intelligence level of the equipment. Technically, they use materials such as tin-plated copper, aluminum wires, and PI / PTFE, combined with high-density integration and multi-layer shielding structures. Their core applications are in industrial automation, new energy, and high-end equipment.

[0003] Existing wiring harnesses for connecting industrial equipment have low tensile strength, making them prone to breakage and damage. They also have short service life, poor heat dissipation, and the ability to transmit data, signals, or current can be affected by overheating during operation. Furthermore, they have poor compressive strength, making them susceptible to damage from compression.

[0004] Therefore, a highly protected industrial data transmission harness is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a highly protective industrial data transmission harness with advantages such as high tensile strength and effective shielding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-protection industrial data transmission harness, comprising a harness body, the harness body comprising a conductor, an inner insulation layer sleeved on the outer side of the conductor, a shielding component sleeved on the outer side of the inner insulation layer, a buffer layer sleeved on the outer side of the shielding component, an outer insulation layer sleeved on the outer side of the buffer layer, and a tensile-resistant component provided inside the outer insulation layer.

[0007] Preferably, the shielding assembly includes a copper mesh, and an aluminum foil is sleeved on the outside of the copper mesh. The copper mesh and the aluminum foil are bonded and fixed together by epoxy resin.

[0008] By adopting the above technical solution, double shielding enhances anti-interference capabilities.

[0009] Preferably, the tensile component includes tensile rings, a plurality of which are provided inside the outer insulation layer, and ten reinforcing ribs are uniformly fixed between the tensile rings.

[0010] By adopting the above technical solution, the tensile force is dispersed, and localized breakage is avoided.

[0011] Preferably, the front side of the wire harness body is provided with an interface assembly, the interface assembly includes a connector, the rear side of the connector is fixedly provided with a housing, and the rear side of the housing is spirally provided with a locking nut.

[0012] By adopting the above technical solutions, the stability of the interface connection is improved.

[0013] Preferably, the outer side of the housing is provided with a fixing component, the fixing component includes a base, a lower fixing ring is fixedly provided on the top of the base, and an upper fixing ring is fixedly provided on the top of the lower fixing ring by bolts.

[0014] By adopting the above technical solution, the displacement of the interface caused by vibration is eliminated.

[0015] Preferably, the outer insulation layer is made of neoprene rubber, and the outer insulation layer and the buffer layer are bonded together with hot melt adhesive.

[0016] By adopting the above technical solutions, we can cope with harsh environments such as oil pollution, humidity, and temperature fluctuations in industrial sites, and avoid cracking or aging of the outer insulation layer.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model effectively blocks electromagnetic interference across the entire frequency range through a dual shielding assembly of copper mesh and aluminum foil, preventing signal leakage or interference. At the same time, the locking nut of the interface assembly and the fixing structure of the fixing assembly can resist interface loosening caused by industrial equipment vibration, ensuring uninterrupted and error-free data transmission.

[0019] 2. This utility model can disperse tensile force and prevent local breakage through the tensile ring and reinforcing rib structure of the tensile component. The outer insulation layer is made of oil-resistant, high and low temperature-resistant, and aging-resistant neoprene rubber material, and is tightly bonded to the buffer layer with hot melt adhesive. It can resist oil stains, moisture, temperature fluctuations and minor impacts in the industrial environment, and greatly extend the service life of the wire harness. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following describes an embodiment of this utility model based on its overall structure.

[0027] like Figures 1 to 4 As shown, this utility model provides a highly protected industrial data transmission harness, including a harness body 1. The harness body 1 includes a conductor 11, which is responsible for transmitting electrical or data signals. An inner insulation layer 12 is sleeved on the outside of the conductor 11, directly wrapping the conductor 11 and isolating the conductor 11 from the external structure to prevent leakage or signal crosstalk. A shielding component 13 is sleeved on the outside of the inner insulation layer 12 to block external electromagnetic interference. A buffer layer 14 is sleeved on the outside of the shielding component 13 to provide physical buffering and absorb minor impacts, compressions, or vibrations from the outside. An outer insulation layer 16 is sleeved on the outside of the buffer layer 14 to isolate the external environment. An anti-tensile component 15 is provided inside the outer insulation layer 16 to improve the overall tensile strength of the harness.

[0028] In this embodiment, the shielding component 13 includes a copper mesh 131 to block mid-to-high frequency electromagnetic interference, and an aluminum foil 132 wrapped around the outside of the copper mesh 131 to block low frequency electromagnetic interference. The combination of the two can cover a wider range of interference and ensure the stability of data transmission. The copper mesh 131 and the aluminum foil 132 are fixed by epoxy resin bonding. Epoxy resin has high bonding strength and is resistant to aging, which can prevent the copper mesh 131 and the aluminum foil 132 from separating during long-term use, ensuring that the shielding effect is durable and that the anti-interference ability will not decrease due to structural loosening.

[0029] The tensile component 15 includes tensile rings 151, several of which are provided inside the outer insulation layer 16. Ten reinforcing ribs 152 are uniformly fixed between the tensile rings 151. The tensile rings 151 and the reinforcing ribs 152 can evenly distribute the tensile force throughout the entire length of the wire harness, rather than concentrating it on a certain section of the conductor or insulation layer, thus greatly reducing the risk of the wire harness breaking due to pulling.

[0030] The front side of the wire harness body 1 is provided with an interface component 2, which includes a connector 21 that directly connects to the device interface. The rear side of the connector 21 is fixedly provided with a housing 22 that covers the connection between the connector 21 and the wire harness, forming physical protection. The rear side of the housing 22 is provided with a locking nut 23 that is screwed on. By rotating and tightening, the housing 22 and the wire harness are firmly fixed to prevent the connection from loosening.

[0031] The outer side of the housing 22 is provided with a fixing component 3, which includes a base 31. A lower fixing ring 32 is fixedly provided on the top of the base 31, and an upper fixing ring 33 is fixedly provided on the top of the lower fixing ring 32 by bolts, for fixing the wire harness as a whole.

[0032] The outer insulation layer 16 is made of neoprene rubber. The outer insulation layer 16 and the buffer layer 14 are bonded together with hot melt adhesive to prevent the outer insulation layer 16 and the buffer layer 14 from separating due to long-term friction or vibration, thus ensuring the stability of the overall structure of the wire harness and preventing moisture or dust from entering through the gaps between the layers.

[0033] The working principle and process of a high-protection industrial data transmission harness:

[0034] Peel off the outer insulation layer 16, buffer layer 14, and shielding component 13 at the front end of the wire harness body 1 in sequence to expose the wire 11 wrapped by the inner insulation layer 12. Weld or crimp the wire 11 to the connector 21 to ensure good conductivity. Then, put the outer shell 22 on the connection between the connector 21 and the wire harness, tighten the locking nut on the back to fix the wire harness. Finally, weld the base 31 of the fixing component 3 to the lower fixing ring 32, and then connect the upper fixing ring 33 to the lower fixing ring 32 with bolts to clamp the outside of the outer shell 22 to complete the assembly of the entire wire harness.
