Description

Technical Field

[0001] The utility model belongs to the technical field of battery detection, and in particular relates to an automatic switching device and automatic detection equipment. Background Art

[0002] With the rapid development of electronic technology, the data processing capabilities of electronic devices such as smartphones are constantly improving, and the application scenarios are becoming more and more complex, which makes the power consumption of electronic devices also increase. Battery measurement of electronic devices is of great significance to both the battery itself and the users of electronic devices.

[0003] During measurement, the battery and the measuring instrument are usually connected via a wiring harness. When measuring multiple batteries, after measuring the battery on one wiring harness, the wiring harness is usually removed from the measuring instrument, and then another wiring harness connected to another battery is switched to obtain different measurement data. At the same time, there is also a situation where the wiring harness that has been measured needs to be reinstalled on the measuring instrument and re-measured for comparison.

[0004] However, when switching and measuring the wiring harness, most of the time the manual switching method is used, that is, manually unplugging the wiring harness from the pin, and then placing another wiring harness to be measured in the specified position. Manually switching the wiring harness for a long time will result in low switching efficiency, visual fatigue and muscle fatigue for the operator, and it will also easily lead to inaccurate measurement data.
