Connection structure of the terminal

To provide a terminals connecting structure which can prevent a terminal of two types of terminals which is mounted later from plunging into an inside of or pushing up a terminal which is mounted first with a simple structure in stacking the two types of terminals one on the other for connection in an electric equipment connecting terminal block. A plunge prevention portion 22 which is bent inwards towards an inverter terminal block 10 is formed at a leading end portion of a capacitor bus-bar terminal 20, and a guide rib 17 is formed on a lateral side of the terminal block 10 which faces an inverter connector terminal 30 in a position lying in proximity to a nut 12A so as to project outwards along a direction in which the inverter connector terminal 30 enters.
