provide power throughout the computer. For example,we want a signal to go from a CPU module or pcb to amemory module or pcb. A signal will leave the CPU atits plug, which is plugged into a connector receptacle.A conductor will route that signal from the CPU’sconnector receptacle to the memory’s connectorreceptacle, where the signal will go from the connectorplug to its destination inside a memory module or pcb.INTERNAL CONNECTOR RECEP-TACLES. —Internal connector receptacles receive theconnector plug of an individual unit (module,subassembly, or pcb) or wiring harness. Connectorreceptacles can have male or female electrical contacts.The sizes and shapes of the electrical contacts vary.Figure 2-23.—Connector receptacle of a module for a pcb.Refer to your computer’s technical manual for details.Receptacle connectors are used in the following places:Frame or cabinet to receive a module or wiringharnessModule to receive a subassembly or pcbChassis or assembly to receive a subassembly orpcbRack or cage to receive a pcbMotherboard or backplane to receive a pcbExamples of connector receptacles are illustrated infigures 2-23 and 2-24. Figure 2-23 shows the connectorreceptacles of a module for receiving pcb’s. Figure2-24 illustrates the connector receptacles of amotherboard.INTERNAL CONNECTOR PLUGS.—Individual units and wiring harnesses will have a plugthat connects into an internal connector receptacle.Again depending on the design, the plug can have maleor female electrical contacts. The connector plugs onthe following units will be plugged into connectorreceptacles:ModuleSubassemblyPcbWiring harnessFigure 2-24.—Connector receptacles of a motherboard.2-19
