Abstract: A terminal board panel comprises a longitudinally elongated frame enclosing a rectangular space, and a plurality of terminal boards disposed end-to-end in a longitudinal column in such space. Each board on its laterally opposite sides has outwardly projecting flanges cooperating with inwardly projecting flanges on two rails on laterally opposite sides of (and forming parts of) the frame to lock the board to the frame by tongue-and-groove couplings. Ones of the flanges on the boards and on the rails comprise an alternation of projecting tabs and of gaps between such tabs to permit the "tongue" of the associated coupling to be inserted in the "groove" thereof by a transverse relative vertical movement of board and frame by which the tabs of one of such flanges passes through the gaps in the other.

Abstract: A terminal board has a base plate and rows and columns of terminals upstanding from such plate. Each terminal comprises (a) an insulative hollow post (b) a metallic terminal strip in the post and having a pair of tangs separated by a contact gap and projecting above part of the post, and (c) a hollow cap fitted on such post to enclose such tangs and gap and shiftable on such post between up and down detained positions. The cap on opposite sides has entrance and exit holes aligned diagonal to such rows and columns, with the entrance hole having an inwardly downward slant and the exit hole being horizontal. With the cap in up position, an insulated lead is fed into the entrance hole and then passed partly or fully through the exit hole which initially impedes full passage through it of the lead.The cap is then pushed on the post to down position to cause the lead to be driven against the tangs and into the contact gap such that the lead's insulation is cut and the metallic core of the lead contacts the tangs.
