With the continuous improvement of safety, comfort and environmental protection requirements of modern cars, the number of circuits and power consumption on the car have increased significantly, so how to arrange a large number of wiring harnesses in a limited car space more effectively and more reasonably becomes a car Problems facing the manufacturing industry. This article focuses on the layout of the automotive wiring harness, briefly introduces the precautions in the layout of the automotive wiring harness.

(1) According to the actual installation position of the wire harness on the vehicle. In order to avoid the sagging and displacement of the harness, considering the weight of the harness, the fixing method and the convenience of the fixing position, it is necessary to fix the harness with sufficient and reasonable fixing points and fixing methods.

(2) According to the direction of the harness and the specific shape of the car body, there are fixed points. The distance between the two fixed points is generally not more than 300 mm; there is no support point on the straight line distance; a fixed point can be set at the position of the obtuse corner; the right angle inflection point Two fixed points should be set, and sharp corners should be avoided in the wiring harness.

(3) According to the shape and outer diameter of the wire tube bundle, the type and size of the fixing buckle should be selected to meet the needs of bearing the weight of the tube bundle.

(4) Where the connector is connected to other wiring harnesses and electrical appliances, the fixing point should be set at an appropriate position not exceeding 120 mm in front of the connector.

(5) Consider setting a fixed point on the main line at the position of the fulcrum, the distance between the fixed point and the fulcrum is not greater than 100 mm

(6) In the installation direction of the fixed buckle, there must be enough space to facilitate the installation and removal of the buckle.
