How to draw auto wire harness drawing?
Solution 1: According to the wiring harness configuration list of the vehicle and the wiring harness direction in the 3D wiring diagram, the measurement tools in CATIA are used to measure the required sizes of each trunk, branch, buckle, cable tie and rubber parts according to the drawing requirements of the wiring harness diagram. The 2D diagram can be arranged through reasonable design, and the outline of the wiring harness diagram can be basically determined. Solution 2: In the process of automobile circuit design, in order to understand the actual situation of automobile electrical equipment in detail and facilitate the arrangement and connection of automobile circuit, engineers need to rely on the schematic diagram, automobile circuit diagram and application diagram. Although the diagram reflects the actual installation position of the electrical equipment on the vehicle, the criss-cross wires in the diagram increase the difficulty of reading the diagram. In order to make the circuit diagram more close to the reality, it is often necessary to draw the wiring harness installation diagram. Wiring harness diagram is the whole car circuit diagram drawn according to the actual installation position of electrical equipment on the car, mainly based on the formation of wiring harness, the drawing surface of the line is less, the expression of the connection between the components has become its main content, in order to express the color of the wire, the terminal code of the joint, often supplemented with wiring harness grouping and terminal number table and wiring harness terminal wiring table. The contents of the wiring harness First, the composition of the wire harness The automobile wiring harness diagram is composed of multiple wiring harnesses, including main line harnesses and branch wiring harnesses. The diagram should show the composition of each wire harness, how many branches there are on each harness, how many wires there are on each branch, the color of the wire and what the stripes are. Two, the length of the wire harness The length of the wire harness includes the total length of the wire harness, the length of each branch and the length of the interval between two wire ends. Three, connection code and connection mark The number of electric appliances on the car is large and complex, in order to make the connection correct, each connection point should be marked with connection code and connection mark, so as to facilitate the connection. Four, the adapter Because there are multiple wiring harnesses, wiring harnesses and wiring harnesses, branches and wiring harnesses, or branches and electrical appliances are all connected through the connector, it should be indicated how many wires on each connector, where each wire is located in the wiring hole of the connector, what kind of shape of the connector, whether the adjacent several connectors are easy to be confused. Color of wire In order to make you understand the...
