Terminal block, particularly for the electrical connection of printed circuit boards

A terminal block, particularly for the electrical connection of printed circuit boards, comprising an enclosure made of insulating material adapted to accommodate at least one electrical cable, and grip means adapted to retain said at least one electrical cable inside said enclosure;

• wherein said enclosure comprises a first side, a second side opposing the first side, and an external surface, wherein the first side and the second side are both perpendicular to the external surface, wherein the external surface extends from the first side to the second side, wherein said enclosure is a monolithic body, and wherein said enclosure comprises at least opening, wherein the at least one opening is adapted to allow said at least one electrical cable to pass into said enclosure,
• wherein the external surface is adapted to receive a pressure, and on an inner side of said enclosure that corresponds to said external surface there being at least one protrusion, which protrudes from said enclosure and is adapted to abut against said grip means;
• wherein said external surface is configured to elastically deform and transmit, through the protrusion, the pressure applied to said external surface to said grip means, wherein the protrusion is adapted to deactivate said grip means;
• the deactivation of said grip means allowing the insertion or release of one or more said electrical cables in or from said enclosure.
