PROBLEM TO BE SOLVED: To prevent breakdown of a contact pin, when a cover member is closed without housing an IC package in an IC socket.SOLUTION: When cover members 30a, 30b are closed while housing an IC package 2 on a floating plate 40, the IC package 2 and floating plate 40 descend by the pressing force of the cover members 30a, 30b, and whereby the terminal 4 of the IC package 2 touches the tip of the first contact member 65 of a contact pin 60. Meanwhile, when the cover members 30a, 30b are closed without housing an IC package 2 on a floating plate 40, the package body 3 of the IC package 2 abuts against a movable spacer 29 and a movable plate 26 descends. Consequently, the step 66 of a first plunger 61 pushes down the step 26b of the movable plate 26, and whereby the first plunger 61 is pushed down, thus maintaining a state where the first plunger 61 is housed in the through hole 40a of the floating plate 40.SELECTED DRAWING: Figure 4 |
