Do you know what a harness is? What are the parts

2022-04-27
The wiring harness provides the whole service item equipment for a certain load source group, such as wireless relay routes, switching devices, automatic control systems, etc. The basic research direction of the basic theory of traffic is to scientifically study the relationship among traffic volume, call loss and wire harness volume. Therefore, wire harness is a key basic element in the basic theory of traffic.
The load source is the service item target of the wire harness, which generally refers to the customer equipment; in a broad sense, the upper-level equipment is the load source of the lower-level equipment. In telephone communication, the load source is also called the call source. The wire harness often contains the number of service item equipment, which is called the wire harness volume. All load sources for an outgoing call can occupy a spare service item equipment in the wire harness.
In order to facilitate the installation and maintenance, and to ensure that the electrical equipment can work under the most extreme standards, the wires of different specifications, models and colors commonly used in the electrical equipment of the vehicle are integrated according to effective distribution, and Use insulating material to tie the wires to the whole bundle, which is both detailed and reliable.
The electrical equipment in the car selects the cross-section of the commonly used wires according to the size of the load current. Electrical equipment in long-term work can use 60% of the current carrying capacity of the specific cable of the wire; electrical equipment in short-term work can use 60%-100% of the specific cable current carrying capacity of the wire.

In order to facilitate identification and maintenance, the wires in the wire bundle are selected in different colors. In order to be convenient to indicate in the circuit schematic diagram, the color of the transmission line is indicated by English letters, and the color it means has a note in each route map.
