1. A switchboard multifunction terminal block for connecting electrical wires (2,2a), comprising:
an insulating body (10) formed by a substantially closed-ring frame (11) and configured so as to define at least a top side (11a) and a bottom side, opposite in a vertical direction (Z-Z), and at least two respective flanks (11b) opposite in a longitudinal direction (X-X); wherein inside the body (10) there is formed:
a first pair of seats (12) outermost in the longitudinal direction (X-X) towards the flanks (11b), symmetrical with respect to a vertical central axis (Z-Z), open in the transverse direction (Y-Y) and during use communicating with the exterior via a first respective opening (12a) extending in the vertical direction (Z-Z) to the top side (11a) of the frame (11); the seats (12) being adapted to house means (50) for gripping wires (2) which can be inserted longitudinally into the seats (12) from the frame (11) flanks (11b); a first space (14) centred on the vertical central axis (Z-Z) and bounded in the longitudinal direction (X-X) by respective first partitions (14a) extending in the vertical direction (Z-Z) and vertically interrupted along a heightwise section so as to allow the insertion, in the transverse direction (Y-Y), of a longitudinal conductor lamina (20) designed to restore the electrical continuity between the wires (2), said first partitions (14a) being spaced from each other in the longitudinal direction (X-X) by an amount such as to define a size of the space suitable for housing a jumper (30) of the screw (32) type; wherein the top side (11a) of the terminal block has a first central opening (16b) forming a communication with the exterior for the first space (14), for inserting the respective jumper of the screw type (30);
a pair of second spaces (15) respectively arranged symmetrically on opposite sides of the first space (14) relative to the vertical central axis (Z-Z), each second space (15) being bounded in the longitudinal direction (X-X) by respective second partitions (15a) extending in the vertical direction (Z-Z) and interrupted in the same direction along a heightwise section such as to allow the insertion of the conductor lamina (20) in the transverse direction (Y-Y); the second partitions (15a) being spaced in the longitudinal direction (X-X) from the first partitions (14a) by an amount such as to define a size of each second space (15) allowing housing of a respective jumper (40) of the type with spring lugs (41), wherein the top side (11a) of the terminal block has an undercut (16) with a base (16a); said first central opening (16b) being formed on that base (16a); wherein the base (16a) has two second lateral openings (16c) symmetrically arranged on opposite sides of the central opening (16b) relative to the vertical central axis (Z-Z); wherein each of the two second lateral openings (16c) forms a communication with the exterior respectively, of a respective one of said pair of second spaces (15), for inserting the respective jumper (40) with spring lugs (40) in the vertical direction (Z-Z) from the top side (11a) accessible to an operator. |
