摘要

A connection device comprises a main body (14) including a power source (12) and a first unit (10) having two terminals to which power is supplied from the power source (12); and a connection body (24) including a second unit (20) having two terminals to which power is supplied from the power source when the connection body is connected to the main body. The connection device is characterized in that a connection means (4) includes a first connection portion (1) for connecting one terminal (a) of the first unit (10) to one terminal (c) of the second unit (20), a second connection portion (2) for connecting the other terminal (b) of the first unit (10) to the other terminal (d) of the second unit (20), and a third connection portion (3) for connecting said one terminal (c) of the second unit (20) to a terminal (f) of the power source (12), another terminal of the power source being connected to the other terminal (b) of the first unit (10) all of the connections being made when the connection body is connected to the main body.
