How to place the cable reasonably in a car

With the safety of modern vehicles, the increasing requirements for comfort and environmental protection, the number of circuits and the amount of electricity used in automobiles have increased significantly. How to properly place a large number of wire harnesses in a limited car space has become a problem in the automobile manufacturing industry.

According to the actual installation position of the wire harness on the whole vehicle, in order to avoid the drop and displacement of the wire harness, considering the weight of the wire harness, the fixing method and the convenience of the fixed position, the wire harness must have sufficient and reasonable fixing points and fixed manners for fixing.

According to the direction of the wire harness and the specific shape of the vehicle body, a fixed point is set. The distance between the two fixed points is generally not more than 300 mm in the straight line distance without the fulcrum; a fixed point can be arranged at the inflection point of the obtuse angle; two fixed points are arranged at the right angle turning point; the acute angle The inflection point is avoided in the bundle.

According to the shape and outer diameter of the wire harness, the type and size of the fixed buckle are selected, and the need to bear the weight of the wire harness is satisfied.

In the position of the connector connected to other harnesses and electrical components, a suitable fixed point is considered in a suitable position of no more than 120 mm in front of the connector.

Consider setting a fixed point on the main line at the fulcrum position. The fixed point distance is not more than 100mm.

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