[0024] The connector is connected to the aging test fixture through a line and is used to connect to the interface in the aging test chamber to complete power supply.

[0025] Beneficial effect: The utility model discloses a trolley assembly for stacking jigs. The utility model designs the placement rack for the aging test jig after the PCBA board is installed into a drawer rack, which can be pulled along the rack body. Then, when placing the aging test jig, the drawer rack can be pulled out and then put in, avoiding the problem of the lower drawer rack being blocked by the upper drawer rack when taking and placing the aging test jig. At the same time, the limit piece is designed to adapt to the lock column on the trolley to fix the trolley and the trolley, avoiding the problem of the trolley moving after being placed on the trolley.
