The power input connector is in-vehicle trouble diagnosis. By connecting to the system (OBD) insertion port, the power supplied to the on-board failure diagnosis system (OBD) is acquired, and output to an external electronic device via the power output connector to drive it. The power adapter, which does not require a separate power supply or power cord, provides a stable power source to drive the electronic device and at the same time improves the applicability of the on-board fault diagnosis system (OBD) outlet It is something to be made.

  In all of the above inventions, a connector is connected to the insertion port of the in-vehicle type fault diagnosis system, and an electronic device of other transmission standards is connected by the connector. For example, it is possible to convert the standard of the insertion port of the in-vehicle type fault diagnosis system into the transmission form of the external electronic device. However, if it is necessary to connect an external device that meets the standards of an on-vehicle failure diagnosis system, such as a personal computer at an automobile repair shop, the adapter must be removed and reconnected after completion of use. Inconvenience remains.
