The insulating base 2 includes a sheet-shaped base 21 and a connecting portion 22 extending from one side of the base 21. Base 2
A plurality of parallel terminal storage grooves 210 for storing one conductive terminal 4 are formed inside the base 21. A pair of protruding ridges 212 are formed on each side 211 of the base 21 that is perpendicular to the connecting portion 22. A cylindrical groove 220 for accommodating the driving device 3 is further provided on the coupling portion 22.

The cover 1 covering the insulating base 2 includes an upper surface 10, a lower surface 11 and a pair of side walls 12 extending vertically from opposite sides of the lower surface 11. The neck 13 extends from the boundary of the upper surface 10 and the side wall 12
Be vertical to. The upper surface 10 is projected in a direction perpendicular to the neck portion 13 of the side wall 12, and a compounding portion 131 for fitting with the drive device 3 is provided. The holding portion 14 is the side wall 1
It is formed on the outside of 2.

As shown in FIG. 2, a flat portion 142 is provided at one end of the holding portion 14, and a slanting base 140 is provided at the other end. The protrusion 141 extends upward from the side of the sloping platform 140 to form a channel 143 between the protrusion 141 and the side wall 140. The locking blot 15 is provided on the outside of the side wall 12 on which the holding portion 14 is provided, and a pair of rectangular grooves (not shown) for slidably accommodating the ridges 212 are provided inside the side wall 12. A plurality of through holes 16 corresponding to the terminal storage grooves 210 of the insulating base 2 are provided in the cover 1.

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 cam shaft 30 includes three annular rotating portions 301 separated by a pair of driven portions 302 and a driven portion 302 connecting the rotating portions 301. The other end of the handle 31 facing the free end 314 is connected to the camshaft 30, and the free end 314 is formed to be 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. The bottom surface 310 is provided with a rectangular groove 311 that is wider than the convex portion 141 of the holding portion 14, and the rectangular groove 311 accommodates the convex portion 141. The cutout 313 is provided on one side of the top surface 312,
This is to limit the sliding of the locking blot 15 of the cover 1.

As shown in FIGS. 1 and 4, when mounting,
First, the cam shaft 30 is installed in the cylindrical groove 220 of the connecting portion 22 of the base 2, and then the cover 1 is slidably assembled to the base 2, and the lower surface 11 of the cam shaft 30 forms the base 2.
To cover. The cam shaft 30 is sandwiched between the compounding part 131 of the cover 1 and the connecting part 22 of the base 2, and when the handle 31 is positioned vertically 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, the terminal receiving groove 21 is inserted with zero insertion force.
By inserting into 0, it is electrically connected to the conductive terminal provided in the terminal accommodating groove 210. When the handle 31 is rotated to the horizontal position, the rotation unit 301 is the mixing unit 131.
The cover 1 is rotated inward and simultaneously with the driven part 302 and the rotating part 301, and the cover 1 is driven so as to slide on the base 2. When the handle 31 is horizontally positioned, the convex portion 141 of the holding portion 14 is housed in the rectangular groove 311 of the handle 31, thereby limiting the lateral movement of the handle 31 and further protecting the drive device 3. It is possible to avoid damage.

As a whole, the present invention has the requirements of patents, and therefore patents should be registered by law. Also,
Since the above is merely specific examples of the present invention and does not limit the scope of the claims of the present invention, any modifications or changes in details that can be made based on the present invention are included in the scope of the claims of the present invention. I shall.
