ABSTRACT
Perhaps the most useful function of electrical connection systems is to serve as a convenience for assembly, installation, and servicing of a device or a system. For example, the internal interconnections inside a timer control module of a dishwasher enable the assembly of such a module. In addition, the electrical connections of the harness to the motor, valves, and power sources complete the entire washer assembly. Likewise, the physical installation of the components such as a motor into a clothes washer drive assembly or a radio into the dashboard of an automobile is done first, and then the electrical circuits are completed by mating connectors or installation of the required electrical connections. As each subassembly is linked, each harness is connected with other circuits and to the power source. Depending on the complexity of the entire electrical system, a variety of connectors such as in-lines, junction splices, device connectors, and headers are used. The overall system architecture of the entire "wiring harness" determines the number of points and where the circuit needs to be connected. Also, depending on the type of components in the circuits, connection systems may serve to connect low-current/voltage, high-frequency electronics circuits, high-current power circuits, timer and control circuits, sensor circuits, and communication signal circuits.
