The two mating connector housings are joined together by a bolt and a nut for secure connection between terminals, the bolt being provided to one of the connector housings, the nut being provided to the other connector housing. The terminals in the connector housings are so arranged in rows that the quantity of terminals per row progressively decreases in proportion to the distance from the center axis of the housings toward the periphery, to reduce over the entire length of the connector housings, the net bending moment applied on the connector housings when the mating terminals are engaged. This prevents the connector housings from being warped and therefore terminals near the periphery from being connected inclined, assuring smooth and secure connection of terminals.
