Description

Technical Field

[0001] This invention relates to a wire and a circuit system, and more particularly to a vehicle wire and a vehicle circuit system. Background Technology

[0002] Based on the requirements of operation, control, and safety, vehicles are generally equipped with mechanical actuation systems and electronic control systems. Taking bicycles as an example, they are typically equipped with hydraulic lines for actuating the braking system, as well as wires for conducting electricity, transmitting signals, and controlling the gear shifting system. Since different functional mechanisms require different lines and wires, a large number of lines and wires are needed. In addition to affecting aesthetics and texture, the numerous lines and wires can easily interfere with and become tangled.

[0003] To enhance aesthetics and quality, some bicycles conceal some or all tubing and cables within the frame tubes. However, due to the limited internal space of the frame tubes, the numerous tubing and cables become extremely crowded and difficult to arrange, and they are also prone to interference and wear.

[0004] Therefore, it is necessary to provide a novel and advanced automotive wiring harness and automotive circuit system to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide an automotive wiring harness and an automotive circuit system through which fluid or core wires driving an actuator can pass, while providing at least one conductive line for signal transmission and / or power transmission applications, thereby significantly reducing the number of wires and avoiding interference and entanglement between multiple wires.

[0006] To achieve the above objectives, the present invention provides a vehicle wiring harness, comprising: a conduit including an outer surface; at least one conductive line extending from the outer surface of the conduit and electrically insulated from the conduit; and an outer covering layer covering the at least one conductive line on the outer surface of the conduit and electrically insulated from the at least one conductive line.

[0007] Preferably, the conduit includes an inner tube and a braided layer disposed on the outer surface of the inner tube.

[0008] Preferably, the inner tube is made of polybutylene terephthalate (PBT), polytetrafluoroethylene (Teflon), thermoplastic polyurethane (TPU), polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), or rubber.

[0009] Preferably, the at least one conductive line is connected to at least one of the inner tube and the outer cladding.

[0010] Preferably, the at least one conductive line is connected to the outer coating.

[0011] Preferably, the outer coating is made of polyvinyl chloride resin, thermoplastic polyurethane, or nylon.

[0012] Preferably, the width of each conductive line is 1.0 mm to 2.6 mm and the thickness is 0.05 mm to 0.15 mm.

[0013] Preferably, the outer surface of the outer coating includes at least one elongated protrusion, which is radially opposite to the at least one conductive line in the outer coating.

[0014] To achieve the above objectives, the present invention further provides an automotive electrical system, including an automotive wire as described above, and further including: a piercing connector, which is fastened to the automotive wire, including at least one piercing end and an external electrical connection end, the at least one piercing end passing through the outer cover and electrically connected to the at least one conductive line, and the external electrical connection end being electrically connected to the at least one piercing end and electrically connected to an external electronic device.

[0015] Preferably, the inner surface of the piercing connector includes at least one elongated groove that corresponds radially to the at least one conductive line.

[0016] The advantages of this invention are:

[0017] The automotive wiring harness and automotive circuit system provided by the present invention allow fluid or core wires to pass through, driving an actuating device, and provide at least one conductive line for signal transmission and / or power transmission applications. Therefore, the number of wires can be greatly reduced and interference and entanglement between multiple wires can be avoided. Attached Figure Description

[0022] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 4 This illustrates an embodiment of the present invention, wherein the vehicle wiring harness 1 of the present invention includes a conduit 10, at least one conductive line 20 and an outer covering layer 30.

[0024] The conduit 10 includes an outer surface. At least one conductive line 20 extends from the outer surface of the conduit 10 and is electrically insulated from the conduit 10. An outer covering 30 covers the at least one conductive line 20 on the outer surface of the conduit 10 and is electrically insulated from the at least one conductive line 20. Thus, the conduit 10 of the automotive wiring harness 1 allows fluid or core wires driving an actuation device (e.g., but not limited to a hydraulic brake device) to pass through, while the at least one conductive line 20 of the automotive wiring harness 1 can provide signal transmission and / or power transmission applications, thereby significantly reducing the number of wires and avoiding interference and entanglement between multiple wires.

[0025] In this embodiment, the automotive wiring harness 1 includes multiple conductive lines 20, which are electrically insulated from the conduit 10, providing multiple signal transmission applications and / or multiple power transmission applications. The conduit 10 includes an inner tube 11 and a braided layer 12 disposed on the outer surface of the inner tube 11, which strengthens the structural strength of the conduit 10. The inner tube 11 is made of polybutylene terephthalate (PBT), Teflon, thermoplastic polyurethane (TPU), polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), or rubber. The outer coating 30 is made of polyvinyl chloride, thermoplastic polyurethane, or nylon or other suitable materials, providing good resilience, abrasion resistance, and resistance to deterioration.

[0026] The at least one conductive line 20 may be made of copper, aluminum, silver, or other metallic or non-metallic conductive materials. The at least one conductive line 20 is connected to at least one of the inner tube 11 and the outer covering layer 30. In this embodiment, the at least one conductive line 20 is connected to the outer covering layer 30. The at least one conductive line 20 can be bonded to the outer covering layer 30 by a hot-pressing method (e.g., a flat flexible cable (FFC) manufacturing process), thereby stably maintaining the at least one conductive line 20 without misalignment due to force or bending, thus exhibiting high stability and reliability.

[0027] Each conductive line 20 has a width of 1.0 to 2.6 mm and a thickness of 0.05 to 0.15 mm. For example, each conductive line 20 has a width of 1.6 mm and a thickness of 0.1 mm. However, the width and thickness of each conductive line 20 may vary depending on different application fields and requirements. The width, thickness, or cross-sectional shape of the multiple conductive lines 20 may be exactly the same, partially the same, or completely different.

[0028] The outer covering 30 can be a single layer or a multi-layer structure. Preferably, the outer surface of the outer covering 30 includes at least one elongated protrusion 31, which is radially opposite to the at least one conductive line 20. In this embodiment, the outer surface of the outer covering 30 includes multiple elongated protrusions 31, which are radially opposite to the multiple conductive lines 20. This improves the protection of the at least one conductive line 20 and allows for quick and easy identification of the location of the at least one conductive line 20, facilitating electrical connection with external objects.

[0029] In signal transmission applications, for example, each conductive line 20 is a copper conductor, with a width of 1.6 mm and a thickness of 0.1 mm, resulting in a cross-sectional area of ​​0.16 mm². 2 Equivalent to 0.455mm diameter American wire gauge (AWG) 25 grade (25AWG grade) copper wire, this specification of conductor can fully meet the requirements for signal transmission.

[0030] In applications involving power transmission, for example, a 25AWG conductor has a resistance of 0.111 ohms per meter and a safe current of 5 amperes per meter. In bicycle applications, the longest conductor is 2 meters (resistance R = 0.222 ohms), and the conductor resistance should not exceed 2% of the actual application. Therefore, the resistance of the application components (such as headlights, taillights, or warning lights) needs to be greater than 11.1 ohms (50 times the conductor resistance). Furthermore, assuming the bicycle's motor system (such as an electronic shifting system) has a voltage of 12 volts (V) and a resistance of 11.1 ohms, its current I is 1.1A (V = IR), and its power is 13.2 watts (W) (W = VI). Therefore, under the above conditions, for applications with a voltage of 12V, a resistance greater than 11.1 ohms, and a power consumption not exceeding 13.2W, this bicycle conductor 1 fully meets the requirements for power transmission and offers high safety.

[0031] In one possible implementation, for example, one of the conductive lines 20 is connected to the negative power supply, and the other conductive lines 20 are connected to the positive power supply. In this way, the automotive wire 1 can provide multiple signal transmission applications and / or multiple power transmission applications. For example, a single automotive wire 1 can serve as a brake line and simultaneously as the control circuit of an electronic transmission system, eliminating the need for a brake line and multiple wires. This significantly reduces the number of wires on a vehicle (e.g., a bicycle) and also allows the automotive wire 1 to be hidden within the vehicle's components without being exposed, greatly enhancing the vehicle's aesthetics and texture, and avoiding interference and entanglement between multiple wires.

[0032] The present invention also provides a vehicle electrical system 100, which includes a vehicle wiring harness 1 as described above. The vehicle electrical system 100 further includes a piercing connector 40, which is fastened to the vehicle wiring harness 1. The piercing connector 40 includes at least one piercing end 41 and an external electrical connection end 42. The at least one piercing end 41 passes through the outer cover layer 30 and is electrically connected to the at least one conductive line 20. The external electrical connection end 42 is electrically connected to the at least one piercing end 41 and is electrically connected to an external electronic device. The external electrical connection end 42 facilitates quick connection, disconnection, replacement, and maintenance. In this embodiment, the piercing connector 40 includes a plurality of piercing ends 41, which pass through the outer cover layer 30 and are respectively electrically connected to the plurality of conductive lines 20. Preferably, the outer coating 30 has sufficient elastic recovery capability so that after the at least one puncture end 41 passes through the outer coating 30 and is removed, it can close the perforation on its own to prevent water seepage or pollution sources from passing through the outer coating 30 and causing adverse effects on the at least one conductive line 20.

[0033] Preferably, the inner surface of the piercing connector 40 includes at least one elongated groove 43, which radially corresponds to the at least one conductive line 20, so that the at least one piercing end 41 can be quickly and accurately aligned and electrically connected to the at least one conductive line 20. More preferably, at least one elongated protrusion 31 of the outer cover 30 is embedded in the at least one elongated groove 43, thereby positioning the piercing connector 40. Preferably, the inner surface of the piercing connector 40 includes a plurality of elongated grooves 43, which radially correspond to the plurality of conductive lines 20 respectively, and the plurality of elongated protrusions 31 of the outer cover 30 are embedded in the plurality of elongated grooves 43 respectively. In this embodiment, the piercing connector 40 is a C-shaped ring buckle. However, it can also be locked with an independent clamping fastener, quick-release clamping mechanism or other clamping mechanism to increase the electrical connection effect between the at least one piercing end 41 and the at least one conductive line 20, and to prevent the piercing connector 40 from loosening, thereby improving stability and reliability.

For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
