Abstract

The invention provides a safe-type detection tool used for a vehicle-mounted sound device. The detection tool includes a tool body. A USB-flash-disk protective device is arranged at a USB-flash-disk interface. The protective device is provided with an inductive module. The safe-type detection tool used for the vehicle-mounted sound device protects the USB flash disk and prevents the burning of the USB flash disk so that manufacturing cost is reduced and at the same time, detection efficiency is ensured.

Description

technical field [0001] The invention relates to a safety detection tool for vehicle audio, belonging to the field of detection devices. Background technique [0002] The current car stereos all have the function of playing songs in the U disk. When producing this type of car audio, a USB flash drive is directly inserted into the testing tool, and once it is installed in the motherboard, the songs in the USB flash drive can be played directly, and the testing efficiency is high. However, during the detection process, the U disk is often burned out due to the short circuit of the USB power supply line or the short circuit of the USB data line, which increases the production cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome existing defects, provide a safe detection tool for vehicle audio, avoid burning out of the U disk, and reduce production costs. [0004] In order to solve the problems of the technologies...
