The roller guide 4 is urged toward the center of the opening 8 of the component guide block 3 by the repulsive force when the coil spring 18 contracts, and the electric component 7 housed in the opening 8 is positioned. After that, a performance test may be performed on the electric component 7 such as an IC package in a predetermined procedure.

  FIG. 7 is a partially cutaway plan view showing a second embodiment of an electrical component socket according to the present invention, and FIG. 8 is a partially enlarged view showing an example of a pressing means applied to the second embodiment. FIG. This embodiment uses a cushion member 19 as the pressing means 5, and the other points are the same as those of the first embodiment shown in FIGS. In this case, the state shown in FIG. 8A shows a steady state in which the electric component 7 is not accommodated in the opening 8 of the component guide block 3, and the cushion member 19 has a normal length which does not expand or contract. I keep it. At this time, the inclined surfaces 4a and 4b of the concave groove 13 of the roller guide 4 are configured to coincide with the extension of the side of the rectangular opening 8. On the other hand, the state shown in FIG. 8B shows a movable state in which the electric component 7 is being accommodated in the opening 8 of the component guide block 3, and two sides of one corner 9 of the electric component 7 are rollers. When the roller guide 4 is pushed in the direction of arrow C by contacting the inclined surfaces 4a and 4b of the concave groove 13 of the guide 4, the repulsive force generated when the cushioning material 19 contracts causes the roller guide 4 to be opened 8 of the component guide block 3. And the electric component 7 is positioned in a state where the electric component 7 is accommodated in the opening 8.

  FIG. 9 is a partially cutaway plan view showing an electric component socket according to a third embodiment of the present invention, and FIG. 10 is a partially enlarged view showing an example of a pressing means applied to the third embodiment. FIG. This embodiment uses a torsion spring 20 as the pressing means 5, and the other parts are the same as the first embodiment shown in FIGS. In this case, the state shown in FIG. 10 (a) shows a steady state in which the electric component 7 is not accommodated in the opening 8 of the component guide block 3, and the torsion spring 20 is not deformed and is not operated. It keeps its shape. At this time, the inclined surfaces 4a and 4b of the concave groove 13 of the roller guide 4 are configured to coincide with the extension of the side of the rectangular opening 8. On the other hand, the state shown in FIG. 10B shows a movable state in which the electric component 7 is being accommodated in the opening 8 of the component guide block 3, and two sides of one corner 9 of the electric component 7 are rollers. When the roller guide 4 is pressed in the direction of arrow C by contacting the inclined surfaces 4a and 4b of the concave groove 13 of the guide 4, the resilient force when the torsion spring 20 is deformed causes the roller guide 4 to be opened at the opening of the component guide block 3. The electric component 7 is biased toward the center of the electric component 8, and the electric component 7 is positioned while the electric component 7 is accommodated in the opening 8.

  FIG. 11 is a plan view showing another embodiment in which the roller guide 4 is provided on the periphery of the opening 8 of the component guide block 3.
