Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a thin-walled insulated communication wire harness. Background Art

[0002] A communication harness refers to a collection of cables and wires used to transmit electrical signals in electronic equipment and systems. It includes various types of cables, such as coaxial cables, fiber optic cables, twisted pairs, etc. Communication harnesses are mainly used to ensure reliable transmission of data between devices or systems during the operation of the equipment. They are widely used in electronic equipment and communication network facilities.

[0003] Nowadays, the internal structure of equipment is becoming more and more compact, and the space provided for connecting wiring harnesses is getting smaller and smaller. This requires the wiring harness itself to compress its own volume and have high flexibility for easy bending. The wall thickness of the insulation layer of the wiring harness is designed to be smaller and smaller to adapt to smaller spaces. Thinner wall thickness allows for more compact wiring layouts, but also reduces the wear resistance of the wiring harness. For this reason, a thin-walled insulated communication wiring harness is proposed to solve the problem of reduced wear resistance of the wiring harness. Utility Model Content

[0004] In order to solve the above technical problems, a thin-walled insulated communication wiring harness is provided. This technical solution solves the problem of reduced wear resistance of thin-walled communication wiring harnesses.

[0005] In order to achieve the above purpose, the technical solution adopted by this utility model is:

[0006] A thin-walled insulated communication wiring harness comprises a core wire harness group, an insulating filling layer is provided on the outside of the core wire harness group, the filler in the insulating filling layer is nitrile rubber, communication wires are provided on the outside of the insulating filling layer, a plurality of communication wires are provided and distributed in a circle around the insulating filling layer, a braided mesh protective cover is provided on the outside of the communication wires, and the braided mesh protective cover is made of a high-density nylon braided mesh.

[0007] Preferably, the communication wire includes a communication wire layer, an insulation layer, a metal mesh shielding layer and a protective layer, the insulation layer is coated on the outside of the communication wire layer, the outside of the insulation layer is coated with a metal mesh shielding layer, and the protective layer is coated on the outside of the metal mesh shielding layer.

[0008] Preferably, the insulating layer is made of polytetrafluoroethylene.

[0009] Preferably, the metal mesh shielding layer is a mesh sleeve woven with copper wires.

[0010] Preferably, the protective layer is made of composite polyurethane material and is filled with aramid fibers.

[0011] Preferably, the core wire bundle group is composed of multiple wires twisted together.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. A braided mesh protective cover is set on the outside of the wire harness. The braided mesh protective cover is made of nylon fiber through tight weaving, which makes the internal communication wires fit more closely to the insulating filling layer, making the wire harness tighter, while providing additional protection for the wire harness and improving the wear resistance of the wire harness.

[0014] 2. A metal mesh shielding layer is set inside the communication cable to improve the anti-interference ability, and the outer protective layer improves the wear resistance of the cable and increases the service life of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present invention. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0019] As shown in the figure, a thin-walled insulated communication wiring harness includes a core wiring harness group 1, which is composed of multiple wires twisted together. An insulating filling layer 2 is provided on the outside of the core wiring harness group 1. The filler in the insulating filling layer 2 is nitrile rubber, which provides insulation protection for the core wiring harness group 1. Nitrile rubber has good flexibility, wear resistance and impact resistance, which can greatly improve the flexibility of the wiring harness. The wiring harness is easier to bend in a narrow space, and the insulating filling layer 2 is not easy to break. Communication wires 3 are provided on the outside of the insulating filling layer 2. There are multiple communication wires 3 and they are distributed in a circle around the insulating filling layer 2. A braided mesh protective cover 4 is provided on the outside of the communication wires 3. The braided mesh protective cover 4 is made of high-density nylon braided mesh. The braided mesh protective cover 4 is tightly woven to make the internal communication wires 3 fit more closely to the insulating filling layer 2, and the nylon fiber has high tensile strength and wear resistance, which can provide additional protection for the wiring harness.

[0020] The communication wire 3 includes a communication conductor layer 31, an insulating layer 32, a metal mesh shielding layer 33 and a protective layer 34. The insulating layer 32 is coated on the outside of the communication conductor layer 31, and the outside of the insulating layer 32 is coated with a metal mesh shielding layer 33. The protective layer 34 is coated on the outside of the metal mesh shielding layer 33. The insulating layer 32 is made of polytetrafluoroethylene, which has excellent insulation properties. The metal mesh shielding layer 33 is a mesh woven with copper wire. The metal shielding mesh surrounds the communication wire 3. Electromagnetic waves hit the metal mesh to generate induced current to reflect and absorb electromagnetic waves, thereby blocking electromagnetic waves and protecting the communication wire 3 against electromagnetic interference and signal crosstalk. The shielding layer has a good shielding effect against high-frequency interference. The protective layer 34 is made of a composite polyurethane material and is filled with aramid fiber. Compared with other plastics and rubbers, polyurethane has higher wear resistance, and also has excellent elasticity and tear resistance. It is not easy to crack and break, which can reduce the wear of the wiring harness by the external environment and improve the service life of the wiring harness.

[0021] This solution provides insulation protection for the internal core wire harness group 1 by setting an insulating filling layer 2, provides anti-electromagnetic interference protection for the communication wire 3 by a metal mesh shielding layer 33, and improves the wear resistance of the wire harness by setting a polyurethane material protective layer 34 on the outside of the communication wire 3 and a braided mesh protective cover 4 on the outside of the wire harness.

[0022] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
