Abstract

PURPOSE:To positively test a printed circuit board without breaking the same by providing a retainer member made of an elastic body at both sides of a probe connected to said printed circuit board. CONSTITUTION:A probe holder 3 which is fixed to a free end of a leaf spring 2 supports a probe 4. A retaining spring 5 is fixed to the opposite surfaces of the probe holder 3. After a carrier 1 is moved to position the probe 4, a solenoid 11 is actuated, whereby a bell crank 8 is turned to press the holder 3 via a ring spring 9. When the holder 3 is depressed while the spring 2 is being bent, a shock absorber 6 mounted to the spring 5 strikes the circuit board to press the same against a table. Then, the spring 5 brings the circuit board into tight contact with the table, with the holder 3 descending, so that the probe 4 is brought into contact with a testing point. Therefore, the contact pressure of the probe 4 to the testing point can be reduced, thereby preventing dents from being left. Further, failure in measurement by the levitation of the circuit board can be avoided, assuring positive testing.
