Abstract: An IC socket includes: a heat transfer member attached to a socket body in a manner capable of contacting an electrical component and having an opening penetratingly formed at a contact surface that contacts the electrical component accommodated in the socket body; and a temperature sensor that is mounted in the opening of the heat transfer member and has a rod-like tip end portion including a thermosensitive element and extending toward the electrical component, in which the tip end portion, as well as the heat transfer member, contacts the electrical component. In the IC socket, a tubular component having an insertion hole in which an outer surface of a portion of the temperature sensor other than the tip end portion is fitted in a slidable manner in the axial direction of the temperature sensor, is attached to the opening.

Abstract: A electric contact pin which can certainly contact a plunger with a contact spring and ensure smooth operation (vertical motion) of the plunger. The present invention can execute electrical tests of the electrical parts accurately. The electric contact pin according to the present invention contacts an eccentrical portion of an open coil portion provided for the contact spring capable of easily deforming in a radial direction with a conductive portion of the plunger. Consequently, the conductive portion of the plunger is elastically pinched between the eccentrical portion of the open coil portion and the closed coil portion. The eccentrical portion of the open coil portion and the closed coil portion are contact with the conductive portion of the plunger at any time.

Abstract: A socket for an electrical part includes a pressing member mounted to the socket body accommodating an electrical part to be rotatable and configured to press the electrical part in a horizontal position thereof, an operation member provided for the socket body to be vertically movable and configured to rotate the pressing member, and a latch member provided having an engaging pawl to be engaged with the socket body in the horizontal state of the pressing member. The latch member is provided with a pressed portion, and when the operation member is moved downward in a state that the latch member is engaged with the socket body, an engagement releasing member formed to the operation member presses the pressed portion to rotate the latch member so as to release the engagement of the latch member with the socket body.

Abstract: A socket for an electrical part is provided with a pressing member to press the electrical part in a horizontal position thereof, and an operation member provided for the socket body to be vertically movable and configured to rotate the pressing member. The operation member is provided with an operating portion for pressing and rotating an operated portion formed to the base end portion of the pressing member. The operating portion includes a first operating portion pressing downward a first operated portion of the operated portion so as to rotate the pressing member in an opening direction thereof from a horizontal state when the operation member is moved downward, and the operating portion further includes a second operating portion pressing upward a second operated portion of the operated portion so as to rotate the pressing member in a closing direction thereof from a standing position when the operation member is moved upward.
