RELAY UNIT
First Claim
1. A relay unit housed in a battery case, the relay unit comprising:
- a first bus bar;
a relay that is electrically connected to the first bus bar; and
a device cover that covers the first bus bar and the relay, whereinthe device cover includes an upper member which has a box shape with an upper end closed and with an opening formed at a lower end, and a lower member which is combined with the upper member in a manner to close the opening of the upper member,the lower member is formed from a resin having a higher heat conductive property than the upper member,the first bus bar is connected to the lower member in a manner to allow transfer of heat, via a first inner heat conductive sheet placed between the first bus bar and the lower member, andthe first inner heat conductive sheet is an electrically insulating resin sheet having a lower surface hardness than the lower member.

Abstract
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.
