This connection method has the advantage of saving labor and speed, and the most important thing is that it will not cause any damage or distortion to the connecting pins of the pin-type connector, which ensures the damage-free insertion of the connector during the test. In this connection method, the vertical movement of the connector of the test circuit board embedded in the vertical press-fit mechanism can be realized by pulling out the vertical press-fit mechanism upwards, and the vertical movement of the vertical guide column is limited by the guide hole. take off.
