Example 1. FIG. 1 is a structural explanatory view showing an embodiment of the present invention. FIG. 2 is a plan view of the state in which the two devices in FIG. 1 are connected to each other as seen from above. 3A and 3B are structural views after assembly for explaining the state of the power supply terminal on the card basket side in FIG. 1, FIG. 3A being a side sectional view and FIG. 3B being a rear view. In the figure, 1 is a power supply device and 2 is a card basket. Reference numeral 11 denotes a first terminal provided on the power supply device, which is naturally insulated from the housing. Reference numeral 12 is a backplane on the power supply unit side, 21 is a back panel of the card basket, and 22 is a screw. A second terminal 23 is made of an elastic conductor. Reference numeral 24 is an insulator to which the second terminal group is attached.

In this embodiment, one of the devices is the power supply device 1, and the first terminal group 11 for the first connection is attached to the rear surface of the power supply device 1 via an insulating portion. The type of power supply for the terminals is, for example, + 5V, ground (GND), + 24V, -2.
4V or the like. On the other hand, the other device is a card basket for accommodating a plurality of cards, and the second terminal group 23 is mounted on the insulating plate 24 on the rear surface thereof. The terminal 23 is a plane having elasticity, and power is supplied to necessary portions in the basket by screws 22.
