摘要： A control unit includes: an input portion that receives the positional information of a vehicle; a calculation unit that generates a control signal for controlling an electromagnetic relay; and an output portion that outputs the control signal to the electromagnetic relay. The calculation unit determines whether a location region of the electromagnetic relay is a relay-freeze region, the location region being identified by the positional information of the vehicle, and, when the location region of the electromagnetic relay is a relay-freeze region, performs a freeze inhibiting process for preventing the electromagnetic relay from being frozen or defrosting the electromagnetic relay by opening and closing the electromagnetic relay and causing the electromagnetic relay to vibrate.

摘要： This relay unit includes: a first bus bar; a relay electrically connected to the first bus bar; and an apparatus cover for covering the first bus bar and the relay. The apparatus cover includes: an upper member in a box shape having a covered upper end, the upper member having an opening formed in a lower end; and a lower member bonded to the upper member such that the opening of the upper member is covered with the lower member. The lower member is formed of a resin having heat conductivity that is higher than that of the upper member. The first bus bar is connected to the lower member via a first inner heat conductive sheet such that heat can be transferred to the lower member, said first inner heat conductive sheet being disposed between the first bus bar and the lower member.

摘要： Provided is an electromagnetic relay which can sufficiently dissipate heat generated from a coil to secure desired attracting force even when the electromagnetic relay is miniaturized. The electromagnetic relay includes an electromagnet block and a contact switching mechanism. A movable contact piece of the contact switching mechanism includes a contact attaching portion to which a movable contact is attached, and a first fixed portion attached to a first movable iron piece of the electromagnet block. The first fixed portion is in surface contact with the movable iron piece and is substantially equal in width dimension to the movable iron piece.

摘要： An electromagnetic switch has a movable contact and a stationary contact accommodated and sealed in a container of a given shape. In the container, there are provided at the axial top and bottom of the container, meander venting paths for communicating the inside of the container with surrounding atmosphere. The ventilation of the inside of the container is thus effectively attained by the meander paths so that the formation of ice on the stationary contact can be prevented.
