PURPOSE:To surely perform electrical connection of an element to be measured and a measuring device by tightly press-contacting connecting pins of the element to be measured and the contact points grasping the connecting pins by means of a rotary solenoid. CONSTITUTION:When an electric apparatus 9 is inserted into the guide hole 10A of a guide plate 10, the apparatus 9 is placed on a mounting plate 8 without causing any clatter. At this time, connecting pins 9A are inserted through pin insertion holes 8B, and are grasped between the contact points 3A of catching springs 3. When a power source switch is turned on, a rotary solenoid 6 is energized to move spring pinching plates 4, 5 in mutually opposite directions by way of an eccentric arm 6B, then the overlaps formed by spring through-holes 4A and 5A are narrowed and two pieces one set of the catching springs 3 are pressed to each other, so that the pins 9A are tightly press-contacted by the forces of the springs and the pinching forces of the plates 4, 5. Thereby, the contact between the contact points 3A and the pns 9A is accomplished perfectly, and the occurrence of unbalance in contact resistance is obviated. |
