Description

Technical Field

[0001] This utility model relates to the field of wire harnesses, specifically lightweight high-strength alloy wire harnesses. Background Technology

[0002] A wiring harness is a general unit of service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. In order to facilitate installation and maintenance and ensure that electrical equipment can work under the worst conditions, the wires of different specifications and colors used by all electrical equipment in the vehicle are combined into one unit through reasonable arrangement and bundled with insulating material. This is both complete and reliable. This is the most basic wiring harness style.

[0003] Wiring harnesses have a wide range of applications, especially in the automotive field. In modern cars, electronic control systems are closely related to wiring harnesses. Someone once used a vivid analogy: a microcomputer is like the human brain, sensors are like sensory organs, actuators are like motor organs, and wiring harnesses are like nerves and blood vessels. With the increasing functionality of automobiles and the widespread application of electronic control technology, the number of circuits and power consumption in cars have increased significantly, making wiring harnesses thicker and heavier. How to more effectively and rationally arrange a large number of wiring harnesses within the limited space of a car, and how to maximize their functionality, has become a problem facing the automotive manufacturing industry. Currently, most wiring harnesses on the market are simply multiple cable ends merged together, resulting in a disorganized and structurally weak harness. When subjected to dragging or pulling, the harness is prone to breakage, exposing the internal fiber core and affecting its normal operation. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight, high-strength alloy wire harness to solve the problem of low structural strength in existing wire harnesses mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: a lightweight high-strength alloy wire harness, including a composite cable harness, wherein the end of the composite cable harness is provided with a terminal, and a circuit box electrically connected to the composite cable harness is installed on the terminal, and the circuit box is provided with a terminal block that is electrically connected to an external device by plugging in.

[0006] The composite cable bundle includes an outermost protective sheath, which is fixedly connected to a filling layer via a support frame. An adhesive layer is provided at the center of the filling layer, and an alloy main wire is provided inside the adhesive layer. Multiple electromagnetic shielding rings are regularly arranged around the adhesive layer, and an insulating protective layer is provided inside the electromagnetic shielding rings. An electrical signal transmission cable is provided inside the insulating protective layer.

[0007] Preferably, an inflatable interlayer is filled between the outer protective sleeve and the filling layer.

[0008] Preferably, the gas-filled interlayer uses argon gas.

[0009] Preferably, the filling layer is made of aerogel material.

[0010] Preferably, the adhesive layer is fixedly bonded to the filler layer, and the filler layer is fixedly bonded to the alloy main wire.

[0011] Preferably, the electromagnetic shielding ring and the filling layer are fixedly bonded together with insulating adhesive.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0013] This lightweight, high-strength alloy wire harness uses a single-core alloy material as its base, which greatly improves the structural strength of the wire harness itself, making it more resistant to tension and drag, and extending its service life. At the same time, this invention reduces weight while maintaining high strength, making it easy to carry and use. Attached Figure Description

[0018] 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.

[0019] See Figures 1-2 The lightweight high-strength alloy wire harness includes a composite cable harness 1, with a terminal 2 at the end of the composite cable harness 1. A circuit box 3 electrically connected to the composite cable harness 1 is installed on the terminal 2, and a wiring terminal 4 electrically connected to an external device via a plug-in connection is provided on the circuit box 3.

[0020] The composite cable bundle 1 includes an outermost protective sheath 101. The outer protective sheath 101 is fixedly connected to the filling layer 104 through a support frame 103. An adhesive layer 108 is provided at the center of the filling layer 104. An alloy main wire 109, which only provides tensile strength and does not transmit electrical signals, is provided inside the adhesive layer 108. Multiple electromagnetic shielding rings 105 are regularly arranged around the outside of the adhesive layer 108. An insulating protective layer 106 is provided inside the electromagnetic shielding rings 105. An electrical signal transmission cable 107 is provided inside the insulating protective layer 106.

[0021] See Figure 2 An inflatable interlayer 102 is filled between the outer protective sleeve 101 and the filling layer 104. This arrangement can provide a buffer for the bending of the composite cable bundle 1 through the inflatable interlayer 102, so that the bending life of the composite cable bundle 1 is longer.

[0022] See Figure 2 The air-filled interlayer 102 uses argon gas, which is an inert gas with good insulation and flame retardant effects, and can improve the overall performance of the composite cable bundle 1.

[0023] See Figure 2 The filling layer 104 is made of aerogel material. Aerogel has good thermal insulation properties and low density, which can reduce the amount of material in this device while maintaining the stability of the composite cable bundle 1 structure.

[0024] See Figure 2 The adhesive layer 108 is fixedly bonded to the filling layer 104, and the filling layer 104 is fixedly bonded to the alloy main wire 109. This arrangement allows the filling layer 104 and the alloy main wire 109 to be fixedly connected together through the adhesive layer 108. The alloy main wire 109 provides overall tensile protection for the composite cable bundle 1, which greatly improves the structural strength of the composite cable bundle 1 and prevents the electrical signal transmission cable 107 from being damaged when the composite cable bundle 1 is dragged or pulled.

[0025] See Figure 2 The electromagnetic shielding ring 105 and the filling layer 104 are fixedly bonded together with insulating adhesive. This arrangement allows the insulating protective layer 106 and the electrical signal transmission cable 107 to provide electromagnetic protection and insulation protection for each electrical signal transmission cable 107, ensuring the stability of the signal transmission of the electrical signal transmission cable 107.

[0026] Working principle: When using this cable harness, the user holds end 2 and plugs terminal 4 into the external device. Electrical signals can then be transmitted through terminals 4 and 5 and the composite cable harness 1. During this process, the alloy main wire 109 and the filler layer 104 are fixedly connected together by the adhesive layer 108. The alloy main wire 109 provides overall tensile protection for the composite cable harness 1, greatly improving the structural strength of the composite cable harness 1 and preventing damage to the electrical signal transmission cable 107 when the composite cable harness 1 is dragged or pulled. At the same time, the external insulation layer 106 and the electrical signal transmission cable 107 also provide electromagnetic protection and insulation protection for each electrical signal transmission cable 107, ensuring the stability of the signal transmission of the electrical signal transmission cable 107.

For example, "connection" can mean a fixed connection or an indirect connection via an intermediate component without affecting the relationship between components and the technical effect. It can also mean an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.
