The load source is the service object of the wire harness, usually refers to the user device. Broadly speaking, the upper level device is the load source for the next level device. In telephone communication, the load source is also called the call source, and the number of service devices contained in the wire harness is called the wire harness capacity. Figure 1 is the schematic diagram of the wire harness. The harness has a capacity of V, and it serves N load sources. Any of the load sources that make the call can occupy one of the idle service devices in the harness.
1. In order to facilitate installation and maintenance and ensure that the electrical equipment can work under the worst conditions, the electrical equipment of the whole vehicle with different specifications and different colors of wires through reasonable arrangement, they are integrated into one, and the electrical wires are bound into bundles with insulating materials, so as to be complete and reliable.
2. Normal selection of wire cross-sectional area and color label
1) Correct selection of wire cross-sectional area
The electrical equipment on the car selects the cross-sectional area of the wires used according to the load current. Long time working electrical equipment can choose wire actual load 60%; Short - time working electrical equipment available wire actual load 60%-100%.
2) Selection of wire color mark
For easy identification and maintenance, the wires in the harness are colored differently. For the convenience of marking in the circuit diagram, the colors of the conductors are represented by letters, and the colors represented by them are annotated in each circuit diagram.
