Abstract

A device and method for examining a USB port of a test apparatus are characterized in that before a functional test is performed, with the test apparatus, on an electronic product equipped with a USB interface, the device including a USB connector, a connecting unit, and an alerting unit is connected to the USB port of the test apparatus so as to examine the power supply status of the USB port of the test apparatus. Accordingly, the electronic product equipped with the USB interface is efficiently protected against damage which might otherwise arise from unstable power supply to or an error in the USB port of the test apparatus during the ensuing functional test.

Claims

1. A device for examining a USB port of a test apparatus, consisting of:

a USB connector configured to be plugged into the USB port of the test apparatus which is used for testing an electronic product equipped with a USB interface, wherein the USB connector has pins consisting of a power pin and a ground pin;

a connecting unit having an end electrically connected to the USB connector; and

an alerting unit electrically connected to another end of the connecting unit for receiving power from the USB connector.

2. The device of claim 1, wherein the alerting unit is one of a light emitting element and a buzzer.

3. The device of claim 2, wherein the light emitting element is a light-emitting diode (LED).

4. The device of claim 3, wherein the connecting unit is an extension cord.

5. The device of claim 3, wherein the connecting unit connects the power pin and the ground pin of the USB connector to a positive pin and a negative pin of the LED, respectively.

6. A method for examining a USB port of a test apparatus, particularly examining a power supply status of the USB port of the test apparatus, the method consisting of the steps of:

plugging an examination device to the USB port of the test apparatus via a USB connector, wherein the examination device consisting of the USB connector, an alerting unit, and a connecting unit electrically connecting the USB connector and the alerting unit to form an electrical circuit from the alerting unit and pins of the USB connector, the pins consisting of a power pin and a ground pin; and

determining a power supply status of the USB port of the test apparatus according to a status of the alerting unit of the examination device.

7. The method of claim 6, wherein, when the alerting unit is a light emitting element in a status of normal light emission, it is determined that the power supply status of the USB port of the test apparatus is normal.

8. The method of claim 6, wherein, when the alerting unit is a buzzer in a status of buzz, it is determined that the power supply status of the USB port of the test apparatus is normal.
