    Abstract: A relay state prediction device according to the present invention includes: a voltage value acquisition unit that measures every moment a detected voltage detected from two ends of a shunt resistor; a voltage value difference calculation unit that calculates a voltage value difference between a first voltage value of when the detected voltage becomes minimum by an armature starting displacement after a primary-side switch is turned off and a second voltage value of when secondary-side contacts are opened; a slope calculation unit that calculates a slope at which the voltage value difference decreases as the secondary-side contacts are repeatedly opened and closed in response to the primary-side switch repeatedly turning on and off; and a state prediction unit that predicts the number of openable and closable times from the present time until the voltage value difference reaches a predetermined threshold value based on the voltage value difference at the present time and the decreasing slope.

    Abstract: A socket includes a housing including a connection surface to which an electronic device is connected, and a lever attached to the housing to be rotatable. The lever includes an operation portion that is rotatable between a first position and a second position and a contact portion that extends from the operation portion in a direction approaching the connection surface and rotates about the rotation axis together with the operation portion. The housing includes a restriction protrusion that comes into contact with a protruding portion protruding from the side portion of the electronic device toward the operation portion at the second position to restrict a movement of the electronic device in the first direction and in a direction away from the connection surface when the operation portion is rotated from the first position to the second position in a state where the electronic device is connected to the connection surface.

    Abstract: A relay state determination device includes a voltage value acquisition unit, a contact bounce time acquisition unit, and a state determination unit. The voltage value acquisition unit acquires a voltage value between one pair of contacts mutually opened and closed in a relay. The contact bounce time acquisition unit obtains a contact bounce time indicated by the one pair of contacts based on the temporal change in the voltage value after the ON instruction to the relay. The state determination unit compares the contact bounce time with a time threshold value to determine whether or not the relay 4 has deteriorated.

    Abstract: The disclosure provides a socket that can be held at any position on rails having different width dimensions. The socket includes a housing, which can be held on a rail that has a first side part and a second side part and extends in a first direction. The housing includes a first locking part disposed on one side of the rail in a second direction to be capable of locking the first side part in a third direction; a second locking part disposed on the other side of the rail in the second direction to be capable of locking the second side part in the third direction; and a third locking part disposed between the first locking part and the second locking part in the second direction to face the first locking part to be capable of locking the first side part of the rail in the third direction.
