PURPOSE:To place a plurality of terminal block main units in connection without any warp by setting to 180 deg. a sum of angles, respectively formed, relating to the lower surface of the terminal block main unit, by a plane, which contains a contact point with a side surface of the other terminal block main unit on both side surfaces of the terminal block main unit. CONSTITUTION:A sum of an angle, formed by a plane, which contains a contact point in one side surface of a terminal block main unit 11 with a side surface of the other terminal block main unit, relating to a lower surface of the terminal block main unit, and an angle, formed by a plane, which contains a contact point in an opposite side surface of the terminal block main unit with a side surface of the other terminal block main unit 11, relating to the lower surface of the terminal block main unit, is set to 180 deg.. That is, a 90 deg. angle is formed by both butt part 18, 24 of plane shape relating to the lower surface of the respective terminal block main unit 11. Accordingly, no warp is generated when a plurality of the terminal block main units are connected, even when an extraction taper is set for molding in the terminal block main unit 11. In this way, the lower surfaces of the terminal block main units can be positioned flush with each other. |
