Abstract: An attachment plug includes: a plurality of plug pins; a plurality of screw terminal blocks electrically connected to the corresponding plug pins, respectively; a body block accommodated within a shell for holding the screw terminal blocks; and an electric wire positioning member for holding the electric cords included in a multi-core cable introduced into the shell from outside in the state where the electric cords are positioned to correspond to the respective screw terminal blocks. The electric wire positioning member includes a plurality of hooking pieces for holding the electric cords exposed outside by stripping a sheath of the multi-core cable in the state where the electric cord are positioned to correspond to the respective screw terminal blocks.

Abstract: A screw terminal block 10A includes a terminal plate 12 provided with an insertion hole 12a through which a terminal screw 11 is inserted; and a fastening plate 13 provided with a screw hole 13a to which the terminal screw 11 inserted through the insertion hole 12a is screwed. The screw hole 13a is formed in the fastening plate 13, and a protrusion 13b is provided at right and left sides of the fastening plate 13. Upper and lower locking pieces 12b protruding toward the fastening plate 13 are provided at right and left side ends of the terminal plate 12 to sandwich the protrusion 13b therebetween. The locking piece 12b of the terminal plate 12 and the protrusion 13b of the fastening plate 13 are engaged with each other to restrict the relative rotation of the fastening plate 13 and the terminal plate 12.
