Usually, multiple signals will converge at a certain point or a small area, and the electromagnetic interference between them is quite serious. At the same time, there is no space for shielding and grounding, and it is impossible to filter each signal separately. Due to the heavy test tasks, on-site workers often drag the wiring harness, causing wear and tear of the insulation at the branch points. In addition, frequent modifications may lead to reduced reliability, which requires an increase in monitoring points. The bifurcation point is the preferred location for setting up monitoring points, so it is imperative to increase the number of branch points. Summary of the invention

[0029] An embodiment of the present application provides a wiring harness routing structure.

[0030] A wiring harness routing structure comprises a primary wiring harness, a first node 1, a plurality of second nodes 2 and a third node 3, wherein the primary wiring harness comprises a plurality of secondary wiring harnesses.

[0031] A plurality of the primary wiring harnesses are forked at the first node 1 and a plurality of secondary wiring harnesses to which at least one of the primary wiring harnesses belongs are forked at the first node 1 to form a forked structure;

[0032] A single branch of the bifurcated structure is an independent wire harness or a combined wire harness, the independent wire harness is one primary wire harness or multiple primary wire harnesses, the combined wire harness is a combination of a primary wire harness and a secondary wire harness after branching, the two branches in the branch structure are the combined wire harness, and the primary wire harness in the combined wire harness is one or multiple, and the secondary wire harness in the combined wire harness is one or multiple;

[0033] The independent wiring harness is directly connected to the electrical equipment or is branched at other nodes.

[0034] The combined wiring harness passes through at least one of the second nodes 2, and the primary wiring harness and the secondary wiring harness in the combined wiring harness are bifurcated at the second node 2, and all the secondary wiring harnesses on a single second node 2 are branched out as a branch.

[0035] The secondary wire bundles of the two combined wire bundles pass through different second nodes 2 and converge into a primary wire bundle at the third node 3. The second nodes 2 passed by the secondary wire bundles of the two combined wire bundles are different. The nodes passed by the secondary wire bundles of the two combined wire bundles cover the first node 1, all the second nodes 2 and the third node 3; the secondary wire bundles that branch and then converge, the first node 1, the third node 3 and multiple second nodes 2 are connected into a closed ring structure.

[0036] The independent wire harness branches out from the first node 1 , the third node 3 and each second node 2 .

[0037] like Figure 1 and Figure 2 As shown, the embodiment of the present application is described by taking as an example how two large star-shaped branch points A and B of the original cable structure are decomposed into multiple surrounding branch points A1, A2, A3, A4 and B1, B2, B3, B4 respectively.

[0038] In the original plan, the wiring harness has 7 branches at node A and 16 branches at point B. This application decomposes point A into 4 nodes, namely nodes A1, A2, A3, and A4, and the nodes A1, A2, A3, and A4 are connected into a closed ring structure; decomposes point B into 4 nodes, namely nodes B1, B2, B3, and B4, and the nodes B1, B2, B3, and B4 are connected into a closed ring structure.

[0039] like Figure 3 As shown, more specifically, the first node 1, the second node 2, the third node 3, the primary wiring harness and the secondary wiring harness of the present application are described by decomposing the A node:

[0040] Node A1 serves as the first node 1 , nodes A2 and A3 serve as the second nodes 2 , and node A4 serves as the third node 3 .

[0041] The A1 node has three branches, namely the first branch 41, the second branch 42 and the third branch 43. The first branch 41 includes multiple primary wiring harnesses, the second branch 42 includes multiple primary wiring harnesses and a secondary wiring harnesses among the branched primary wiring harnesses, and the third branch 43 includes multiple primary wiring harnesses and b secondary wiring harnesses among the branched primary wiring harnesses. The second branch 42 and the third branch 43 serve as combined wiring harnesses, and the first branch 41 serves as an independent wiring harness.

[0042] The combined wiring harness of the second branch 42 is bifurcated into four branches at the A2 node, namely the fourth branch 44, the fifth branch 45, the sixth branch 46 and the seventh branch 47. The fourth branch 44 includes a primary wiring harness, the fifth branch 45 includes a primary wiring harness, the sixth branch 46 includes one primary wiring harness, and the seventh branch 47 includes multiple primary wiring harnesses and a secondary wiring harness. The combined wiring harness of the seventh branch 47 is bifurcated into three branches at the A3 node, namely the eighth branch 48, the ninth branch 49 and the tenth branch 410. The eighth branch 48 includes a primary wiring harness, the ninth branch 49 includes a primary wiring harness, and the tenth branch 410 includes a secondary wiring harness.

[0043] The b secondary wire bundles in the combined wire bundle of the third branch 43 and the a secondary wire bundle in the tenth branch 410 are combined into one primary wire bundle at the node A4, and the primary wire bundle in the third branch 43 forks at the node A4 and the combined primary wire bundle.

[0044] Two large star-shaped branch points in the original cable structure are decomposed into multiple branch points arranged in a surrounding manner, thereby dispersing stress and reducing the impact range of other nodes. The relative position of the branch points is reasonably given according to the use of the test bench, which reduces the difficulty of the process production of the wire harness, helps users to lay it conveniently, improves the electromagnetic isolation level and electromagnetic shielding efficiency, enhances electromagnetic compatibility, makes the wire harness product more beautiful, and increases monitoring points, greatly improving the maintainability and testability.

[0045] like Figure 4 As shown, the first node 1, the second node 2 and the third node 3 are provided with a protective cover 5, and the protective cover 5 is provided with an outlet for the branch wire harness to pass through. A node serial number mark 52 is provided on the outer surface of the protective cover 5. Because part of the wire harness is laid under the floor and is not often exposed to the ground, adding these marks helps to facilitate daily inspection, modification and maintenance.

[0046] A protective cover 5 is formed by molding vulcanized rubber material on the outer surface of the first node 1, the second node 2 and the third node 3. According to the on-site survey, the outlet angle is specified, and the outlet of the branch point is molded and vulcanized according to this angle, so that the vulcanized rubber seamlessly fits the protection harness and enhances the mechanical strength of the branch point; molded vulcanization protection is performed on each new branch point to further enhance the mechanical strength of the branch point.

[0047] The protective cover 5 is provided with a plurality of protruding structures on the outer surface of the end of the wire outlet, and the protruding structures are integrally provided with the protective cover 5. The wire outlet end is vulcanized in a concave-convex shape to improve the degree of freedom of bending, so that when the wire harness is pulled, the wire harness at the wire outlet is smoother, the bending curvature is reduced, and the risk of breakage is reduced.

[0048] In one embodiment, some connectors are designed so that the quad-coaxial signal can be transmitted normally, and no accessories are needed at the tail, thereby saving installation space.

[0049] In one embodiment, the tail processing method of some connectors is optimized to make the filling more reliable while ensuring shielding.

[0050] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
