The neck 13 extends from the boundary of the upper surface 10 and is perpendicular to the side wall 12. The upper surface 10 protrudes in a direction perpendicular to the neck 13 of the side wall 12, and a blending portion 131 for matching with the driving device 3 is provided. The holding part 14 is formed outside the side wall 12.
[0009]
As shown in FIG. 2, a flat portion 142 is provided at one end of the holding portion 14, and a tilt base 140 is provided at the other end. The convex portion 141 extends upward from the side portion of the tilt base 140 and forms a channel 143 between the convex portion 141 and the side wall 140. A locking blot 15 is provided on the outside of the side wall 12 where the holding portion 14 is provided, and a pair of rectangular grooves (not shown) for further slidably storing the ridges 212 are provided inside the side wall 12. A plurality of through holes 16 corresponding to the terminal receiving grooves 210 of the insulating base 2 are provided in the cover 1.
[0010]
As shown in FIG. 3, the drive device 3 is formed in a substantially L shape, and includes a handle 31 and a cam shaft 30 extending perpendicularly to the handle 31. The camshaft 30 includes three annular rotating portions 301 separated by a pair of driven portions 302 and a driven portion 302 that connects the rotating portions 301. The other end of the handle 31 opposite the free end 314 is connected to the camshaft 30, and the free end 314 is formed slightly thinner than the other part of the handle 31 and is parallel to the top surface 312 and the bottom surface 310 of the handle 31. A rectangular groove 311 that is wider than the convex portion 141 of the holding portion 14 is provided on the bottom surface 310, and the convex portion 141 is accommodated by the rectangular groove 311. The notch 313 is provided on one side of the top surface 312 to limit the sliding of the locking blot 15 of the cover 1.
[0011]
As shown in FIGS. 1 and 4, when mounting, first, the camshaft 30 is installed in the cylindrical groove 220 of the coupling portion 22 of the base 2, and then the cover 1 is slidably assembled to the base 2. The lower surface 11 covers the base 2. When the camshaft 30 is sandwiched between the blending portion 131 of the cover 1 and the coupling portion 22 of the base 2 and the handle 31 is positioned perpendicular to the cover 1, the terminals (not shown) of the central processing unit chip module are After passing through the through hole 16 of the cover 1, it is electrically connected to the conductive terminal provided in the terminal receiving groove 210 by being inserted into the terminal receiving groove 210 with zero insertion force. When the handle 31 is rotated to the horizontal position, the rotating unit 301 is rotated into the blending unit 131 and rotates simultaneously with the driven unit 302 and the rotating unit 301 and the cover 1 is driven to slide on the base 2. Is done. When the handle 31 is positioned horizontally, the handle 31 is positioned on the holding unit 14 and supported by the holding unit 14. One side of the groove 311 of the handle 31 is fitted into the channel 143 of the holding portion 14. The convex portion 141 of the holding portion 14 is accommodated in the rectangular groove 311 of the handle 31, so that the movement of the handle 31 in the lateral direction is restricted, and further, the drive device 3 can be protected and can be prevented from being damaged. is there.
