Abstract
A terminal base of a power supply device for electric vehicle wherein electrical connection terminals on the vehicle body side can be easily connected to electrical connection terminals on the battery pack side. A base is provided with an opening for accepting an insulator board on which male-side terminals are held. The opening is provided with first lower and upper guides and with second lower and upper guides. A first edge of the insulator board is clamped by the first lower and upper guides from the lower and upper sides. A second edge opposed to the first edge of the insulator board is clamped by the second lower and upper guides from the lower and upper sides. In this manner, the insulator board is supported in a floating state. The tip of each of the male-side terminals is beveled for mating with the female-side terminals during connection.

3. A terminal base of a power supply device for an electric vehicle, the power supply device including a battery case for accommodating battery cells for supplying electric power to an electric motor of an electric vehicle, and the power supply device being mountable to and detachable from the electric vehicle, wherein the terminal base comprises:
-
a base having a substantially rectangular opening for accepting a substantially rectangular insulator board holding a plurality of male-side terminals; a first lower guide projecting toward an opening side along a lower surface of the base at one edge of the opening; a first upper guide projecting toward the opening side along an upper surface of the base from the edge where the first lower guide projects; a second lower guide projecting toward the opening side along the lower surface of the base at an edge opposed to the edge where the first lower guide and the first upper guide project; and a second upper guide projecting toward the opening side along the upper surface of the base from the edge where the second lower guide projects, wherein a first edge of the insulator board is clamped by the first lower guide and the first upper guide from lower and upper sides, and a second edge opposed to the first edge of the insulator board is clamped by the second lower guide and the second upper guide from the lower and upper sides, whereby the insulator board is supported in a floating state, wherein the opening is formed at a position on the base deviated to a vehicle-width-directional one side, wherein a horizontal engagement part is provided and disposed at a position deviated to a vehicle-width-directional other side in relation to the opening and extends in a horizontal direction, wherein the horizontal engagement part is provided at a position such as to be engaged on an upper side with an engagement rib formed on a lower surface of the battery case and thereby to restrain the battery case from escaping to the upper side, wherein the male-side terminals are plate-like in shape and are arrayed with their front surfaces oriented to a vehicle longitudinal direction, wherein the male-side terminals are tapered while having two beveled corners at each of their tips, wherein one of the beveled corners at the two positions is so beveled that, at the time of bringing the battery case closer to the terminal base to cause the female-side terminals accommodated in the battery case to start being connected to the male-side terminals from an oblique direction, the contact of the male-side terminals with the female-side terminals starts with surfaces, and wherein the other of the beveled corners at the two positions is so beveled that, at the time of bringing the battery case closer to the terminal base to cause the female-side terminals accommodated in the battery case to start being connected to the male-side terminals from the oblique direction, the male-side terminals are prevented from being caught on an opening part of an insulator block having the opening part which accommodates the female-side terminals and surrounds the periphery of the female-side terminals.
