PURPOSE: A multi-functional composite connection type circuit tester is provided to be connected to a power line and a bus line of a bread board integrally, by designing a circuit for circuit test on a PCB board. CONSTITUTION: At least one constant voltage ICs(14,16) convert a voltage of a specific input power supply into a constant voltage. At least one bus line connectors(28,30) have a connector with many lines. The bus line connector is connected to a bus circuit pattern formed on a PCB board(10). At least one bus line pin heads(32,34) are connected to each bus line of the bus line connectors. The bus line pin heads comprises a pin head of many lines. The bus line pin head is connected to the bus pin head pattern formed on the PCB board. At least one power line connector(26) has a connector of many lines. The power line connector is connected to the power supply circuit pattern formed on the PCB board. At least one power line pin heads(36,38,40) have a pin head of many lines. The power line pin heads are connected to the power supply pin head pattern formed on the PCB board. |
