Abstract

To facilitate removal of an absorbing member after mounting an insulated housing to a circuit board in an IC socket. The IC socket 1 has the insulated housing 3 and a lever 8 rotatably mounted on this insulated housing 3. Because a latch arm 40 of the absorbing member 36 is engaged with an opening 34 of the insulated housing 3, the absorbing member 36 is mounted on the insulated housing 3. The absorbing member 36 has a tongue piece 42 extended up to the lever 8. When the lever 8 is rotated upward for preparation to load the IC package, the lever 8 pushes up the tongue piece 42. The absorbing member 36 easily comes off the opening 34 because of displacement of this tongue piece 42.
