Abstract: A slot connector terminal structure for an electrical wire, in particular for an electrical terminal block, in which structure at least one conductive connector part is held stationary in a housing (5) provided with a wire-insertion through opening (23) extending facing an insulation-displacement and core-retaining slot (6) in the connector part, which opening makes it possible firstly for a wire to be connected to be inserted transversely above the slot, and secondly for the wire to be subsequently held stationary via its sheath, the housing further including positioning means for positioning a special connection tool, which positioning means are implemented in the form of a projecting element through which a moving blade of the tool penetrates. The projecting element is provided with a slot (13) into which the wire-insertion through opening (23) opens, which slot makes it possible for the blade of a tool to penetrate into and slide along the slot inside the housing.

Abstract: A terminal includes a metal component held in a housing in the form of at least one connection unit having the general plan appearance of a hollow, convex hexagon split on a longitudinal plane about which it is symmetrical for the purpose of connecting a single electric wire via two parallel stripping and retaining slits. Each unit includes two support sides which project in parallel from a fixed base and each of which carries two other sides of the hexagon shaped unit. Each slit is formed between two sides that are symmetrical. The two support sides press against different mutually parallel walls of the housing via respective symmetrically disposed projections.

Abstract: A terminal for electrical equipement in which a wire is held in a wire-insertion duct between a clamping element of a strip and another clamping element constituting the bottom of a cage that surrounds the strips. The wire is held by drive from a screw with the screw being screwed into the cage and pressing obliquely against the clamping element of the strip on the opposite side thereof to its side which faces the clamping element of the cage. The clamping element of the cage is extended by an extension constituting a wire-guide which projects from the cage into the wire insertion duct parallel to the screw axis and which obstructs the duct to guide any wire disposed obliquely in the wire-insertion duct.
