Definition of wiring harness

A harness is a system used to connect load sources to service devices, where the load source is usually a user device or other electrical device. In a broad sense, any upper-level device can be considered a load source for the lower-level device. In telephone communications, load sources are usually called call sources. The number of service devices in a harness is the harness capacity. Figure 1 shows a schematic diagram of a harness, which shows that the harness has a capacity of V and provides services to N load sources. Each load source that places a call has the opportunity to occupy an idle service device in the harness.

In the wiring harness system, the relationship between the load source and the service equipment is particularly important. The load source can be any device that needs to transmit signals or power through the wiring harness, such as telephones, computers, industrial machines, etc. The capacity of the wiring harness determines how many load sources it can serve at the same time, which is crucial to ensure the stability and efficiency of the system in practical applications.

Specifically, when a load source issues a call request, if there is an idle service device in the harness, the load source can occupy this service device to complete its communication or power transmission needs. This dynamic resource allocation mechanism ensures the efficient operation of the harness system, while also making the most of the existing service devices and avoiding resource waste.

In short, as a connecting bridge between load sources and service equipment, the wiring harness plays an indispensable role in modern communication and power transmission systems. Through the reasonable design and use of wiring harnesses, the reliability and service quality of the system can be greatly improved.
