Abstract

The invention discloses a test line for testing charging current and downloaded data, comprising a USB (Universal Serial Bus) interface, a data line and a plug, which are connected in sequence, wherein an earth wire of the data line is provided with a downloading controller and two test jacks; the downloading controller is serially connected with the earth wire; and the two test jacks are respectively connected with the earth wire in parallel. When the charging current is tested, a test device is connected with the two test jacks, one end of the test line is connected with a device to be detected, the other end of the test line is connected with a computer or a charger socket, and the downloading controller is switched off, so that the charging current of the device to be detected can be tested; when a downloading function needs to be realized, only the downloading controller needs to be conducted and the two test jacks are shorted out to be used as a downloading data line, so that a test function or the downloading function of the test line can be realized on the premise of not damaging the data line, the function of the test line is increased, the reutilization rate of the test line is improved and the production cost is greatly reduced.

Description

Technical field [0001] The invention relates to a charging current test tool, in particular to a test line used for testing the charging current and downloading data. Background technique [0002] The charging current is an important indicator to measure the quality of a mobile phone. The charging current of the mobile phone needs to be tested before leaving the factory. Therefore, how to accurately and quickly measure whether the charging current of a mobile phone meets the requirements has become a bright spot for manufacturers to improve work efficiency. [0003] At present, when testing the charging current of mobile phones, it is necessary to destroy the data lines. After a batch of mobile phones are tested, the damaged data lines cannot be used again, which causes a lot of waste. [0004] Therefore, the existing technology needs to be improved and improved. Summary of the invention [0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the presen...
