A transformer withstand voltage test fixture

Abstract

The utility model relates to micro transformer test technical field discloses a transformer withstand voltage test fixture, including base and sliding block, the base is provided with two, one base both ends side all are fixed with the link cylinder, the side of the other base both ends all are fixed with the connecting rod, and the connecting rod can be slidably inserted into the link cylinder, and the surface of link cylinder is connected with the locking bolt that end penetrates to the inside of link cylinder and is in contact with the surface of connecting rod through the way of screwing, and the sliding block is provided with a plurality and is placed in the slide groove that the base surface opens bottom. The utility model technical scheme through setting variable, variable interval sliding block is placed in the slide groove above the base, can choose corresponding number of sliding block according to the number and interval of one side pin of micro transformer and be fixed with corresponding interval, the interval of two bases can be adjusted, can adjust the interval of two groups of sliding blocks and adapt to different model transformers, realize general purpose and avoid the cost increase when testing different model transformers.
