Abstract: The present invention includes a lower plate, an upper plate provided above the lower plate in such a manner that the upper plate is biased so as to be vertically movable, a guide member attached to the upper plate, the guide member guiding vertical movement of the upper plate, and a spring provided below the guide member, the spring biasing the upper plate upward via the guide member. In the lower plate, an insertion hole having a size that allows the spring and the guide member to pass therethrough in a vertical direction is formed. In the insertion hole, a spring holding member that holds the spring is detachably provided. Such configuration enables suppression of warpage of the upper plate caused by a biasing force of the spring and enables work for replacement of the upper plate to be performed easily and quickly.

Abstract: For an electrical component socket including a socket base having a frame shape to which a contact module is to be inserted and attached from below, an embodiment has an objective to allow contact pins to be in contact with a circuit board with stability. The electrical component socket is configured such that the upper-side plate is caused to ascend to an uppermost position by elastic force of urging means in a state where the contact module is not attached to the socket base. In a state where the contact module is attached to the socket base and disposed on the circuit board, the upper-side plate moves down toward a lower-side plate side against elastic force of the contact pins to be positioned at a predetermined base position, so that lower-side contact portions of the contact pins are brought into contact with the circuit board at a predetermined contact pressure.

Abstract: An electric component socket in which a pressing member is not brought into contact with the tip end of the a contact pin when the socket is pressed by the pressing member in a state where an electric component is not housed in the socket. The electric component socket is provided with a movable plate supported so as to move vertically, a floating plate that is provided above the movable plate and houses the electric component, and a movable spacer that protrudes upward from an upper surface of the movable plate. The electric component socket is configured so that the movable plate is thereby moved downward, thereby enabling the regulating section of the movable plate to move the contact pin downward when the movable spacer is moved downward.

Abstract: Provided is an electric contact with a stable electric resistance value. An insertion rod portion passing through a coil spring is provided on a first contact member, and a cylindrical portion in which a part of the insertion rod portion passing through the coil spring is provided on a second contact member. A tilt mechanism tilts the second contact member to bring the insertion rod portion into contact with the cylindrical portion. This can stabilize the electric resistance value. A reduced diameter portion in which the diameter decreases with an increase in the distance from the cylindrical portion is formed at least near a tip of the insertion rod portion. This can suppress changes in the contact pressure of the cylindrical portion and the insertion rod portion to make expansion and contraction operation smooth.
