Description

Technical Field

[0001] This utility model relates to the field of automotive electronic wiring harness technology, specifically, to an automotive electronic wiring harness. Background Technology

[0002] Currently, most automotive electronic wiring harnesses are not properly secured during installation, resulting in messy wiring. Furthermore, after connection, the harnesses are prone to loosening or even detachment due to the bumpy roads encountered during long-term driving. This significantly reduces the stability of the electrical signal transmission, failing to meet user needs. Additionally, existing wiring harnesses often have poor sealing, leading to side leaks and potential short circuits.

[0003] The applicant discovered through a search that Chinese patent document with publication number 212570455U, published on February 19, 2021, discloses an electronic wire harness with a magnetic ring and a long service life, comprising a wire harness assembly, a wire harness sleeve, a first wire fixing sleeve, a second wire fixing sleeve, and a magnetic shielding ring. The wire harness assembly is surrounded by a wire harness sleeve, one end of which is fixedly embedded and glued with a first wire fixing sleeve, and the other end of which is fixedly embedded and glued with a second wire fixing sleeve. Both the first and second wire fixing sleeves have arc-shaped slope-shaped petals on their outer periphery, and threaded sleeves are fitted around the arc-shaped slope-shaped petals of both the first and second wire fixing sleeves. A magnetic shielding ring is fixedly fitted on the wire harness sleeve at one end of the second wire fixing sleeve. This device also fails to solve the aforementioned technical problem.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to provide an automotive electronic wiring harness that has stable connection and good waterproof performance. Utility Model Content

[0005] The purpose of this invention is to provide an automotive electronic wiring harness that offers stable connection and good waterproof performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an automotive electronic wiring harness, including a housing; a sealing structure and a fixing rod assembly are respectively provided on the housing; an inner shell and a wire assembly are respectively provided in the housing; the inner shell includes a connector; the wire assembly is connected to the connector, and both the wire assembly and the connector are connected to the sealing structure; the fixing rod assembly abuts against the wire assembly.

[0007] The sealing structure includes a wrapping ring; the wrapping ring is located at both ends of the outer shell; a waterproof ring is provided in the outer shell; the waterproof ring is located on one side of the wrapping ring; the wire assembly and the connector are both sleeved in the waterproof ring.

[0008] The waterproof ring is provided with an installation groove; a sealing ring is provided in the installation groove; the sealing ring abuts against the inner wall of the outer shell.

[0009] The outer casing is provided with a threaded hole; the fixing rod assembly includes a screw; the screw is connected to the threaded hole; one end of the screw is connected to a handle, and the other end of the screw is provided with a connecting groove; a rotating shaft is provided in the connecting groove; a pressing block is connected to the rotating shaft; the pressing block abuts against the wire assembly.

[0010] The inner shell includes a conductive plate; a wire sleeve is provided on one side of the conductive plate, and the connector is provided on the other side of the conductive plate; the wire assembly is connected to the connector, and the wire assembly is sleeved in the wire sleeve.

[0011] The connector is provided with a mounting hole; the wire assembly includes wires; the wires are connected in the mounting hole.

[0012] The outer casing is provided with anti-misalignment protrusions; the wire assembly is provided with wire loops.

[0013] The fixing rod assembly is evenly distributed on the outer shell; the anti-misalignment protrusion is provided on both sides of the outer shell.

[0014] The beneficial effects of this application are as follows:

[0015] The sealing structure of this application includes a wrapping ring; a waterproof ring is provided on one side of the wrapping ring; a sealing ring is provided on the waterproof ring; the cooperation between the waterproof ring and the sealing ring can ensure that the outer shell completely wraps the inner shell, effectively preventing water from entering the inner shell; at the same time, the wrapping ring further seals the waterproof ring, solving the problem of poor sealing effect of wire harnesses in the prior art, which easily leads to short circuits in the event of side leakage.

[0016] The conductor assembly primarily transmits electrical signals to the inner shell. The two sides of the inner shell are responsible for receiving and transmitting electrical signals, respectively. The outer shell protects the inner shell so that it can transmit signals normally. The sealing ring prevents external moisture and other factors from affecting the circuit transmission inside the inner shell. The wire sleeve provides support for the connection of each conductor, avoiding instability caused by direct connection of the conductor to the conductive plate. This ensures that each conductor can be fixedly connected to the conductive plate, guaranteeing the continuity of the circuit.

[0017] This application features wire loops, which ensure that each wire will not unravel during subsequent extension, guaranteeing the stability of each wire placement and facilitating subsequent inspection and maintenance by staff. While maintaining ease of use, it also enhances aesthetics.

[0018] This application includes a fixing rod assembly, which ensures the stability of each wire during the connection process and prevents the connection with the conductive plate from being affected by shaking or other factors. At the same time, the fixing rod assembly can be adjusted for tightness, which also facilitates the maintenance of wires by the staff. Attached Figure Description
