PURPOSE:To permit a testing jig to be easily changed in accordance with parts, by a method wherein a testing jig is positioned at a predetermined location, and a substrate mounted thereon is driven from one side thereof so as to be connected and secured to a signal transfer unit at the forward side thereof, and is separated therefrom by retraction. CONSTITUTION:Rails 7, 8 connected to a guide rail 6 incorporated in a testing jig 5 are fitted into grooves 20 formed in slide blocks 18 of a mounted substrate 16 thereby to prevent the displacement of the jig 5. At a portion 28, air nipples 34 and couplers 27 are coupled to each other, and a connector 36 is connected to a plug 35. When a pushbutton 37 is depressed, air flows in to advance a rod 25 until a table 16 is brought into contact with a damper 26 while being guided by rods 21. As a result, an edge 41 of a printed board 40 in the jig 5 is inserted into a connector 31 in a signal transfer unit 29 and secured. When a pushbutton 38 is depressed, the rod 25 is retracted to undo the insertion, and the jig 5 stops when abutting against the damper 26. The jig 5 can be lifted upward to be taken out. The constitution makes it possible to readily change the jig 5 with a jig having a proper guide rail 6 in accordance with a sample. |
