Universal meter switching device for ATO system test

Technical Field

The utility model belongs to the technical field of the railway communication and specifically relates to a universal meter switching device for ATO system test is related to.

Background

When a multimeter is used for measuring some male connectors, a meter pen is inconvenient to contact with a fine contact pin, and the meter pen often falls off or slides onto other contact pins in the point-to-point measurement process, so that the measurement progress is directly influenced, and even measurement errors are caused. When a small amount of similar tests are carried out by a tester, the difficulty can be overcome manually, and when a large-scale test of a product in batches is carried out, the operation is a great test for the tester, and errors are easy to occur. For example, in the case of the cable connector used in the north lake cable ATO system, there are connectors of various specifications, such as the remo connector fgg.1b.304, the pin diameter is 0.9 mm, and the pin 1658670 used in the DB electrical connector, the diameter is 0.3 mm, so two sets of multimeters are required, the maintenance cost of the tool is increased, and confusion is easily caused.
