Abstract: A connecting terminal (100) for electrical wires (2,2’,2’’), comprising: a busbar assembly (4) comprising a number of clamping sites (6,6’,6’’) for electrical wires; a number of engagement sliders (8,8’,8’’) for changing the configuration of an associated clamping site of said busbar assembly between an open receiving configuration and a closed clamping configuration and vice versa; an electrically insulating housing (10); wherein in respect of one or more of said clamping sites (6,6’,6’’) said busbar assembly (4) comprises a busbar (12) and a spring portion (14,14’,14’’) , wherein said spring portion comprises a first end (16,16’,16’’) and a second end (18,18’,18’’); wherein said first end of said spring portion being connected to said busbar (12) at a connection site (20,20’,20’’’) at a first end (16,16’,16’’) thereof located at a first end (42) of said busbar; wherein said second end (18,18’,18’’) of said spring portion (14,14’,14’’) comprises one or more engagement parts (22,22’) and a connection part (24); said clamping site (6,6’,6’’) being defined between said busbar (12) and said connection part (24) of said spring portion (14,14’,14’’); wherein said busbar assembly (4) is accommodated in the interior (26) of said housing (10); wherein in respect of one or more of said engagement sliders (8,8’,8’’), said engagement slider comprises a first end (28) and a second end (30); said first end defining one or more engagement elements (34,34’); wherein in respect of one or more of said engagement sliders (8,8’,8’’), said first end (28) of said engagement slider is accommodated in the interior (26) of said housing in such a way that said engagement slider (8,8’,8’’) can be displaced into and partly out of said housing (10); and in such a way that said second end (30) of said engagement slider (8,8’,8’’) extends out of said housing (10) through an engagement slider opening (36,36’,36’’) in said housing (10); wherein in respect of one or more clamping sites (6,6’,6’’) of said busbar assembly (4), said engagement slider (8,8’,8’’) is arranged in relation to said busbar assembly (4) in such a way that when said engagement slider (8,8’,8’’) is displaced partly out of said housing in order to arrive at said open receiving configuration, said one or more engagement elements (34,34’) of said engagement slider engage with said one or more engagement parts (22,22’) of said spring portion (14,14’,14’’) in the sense that the tension of said spring portion is increased, thereby creating a relative wide gap between said busbar (12) and said connection part (24) of said spring portion (14,14’,14’’); and in such a way that when said engagement slider (8,8’,8’’) is displaced into said housing (10) in order to arrive at said closed clamping configuration, said one or more engagement elements (34,34’) of said engagement slider at least partly disengage with said engagement parts (22,22’) of said spring portion (14,14’,14’’) in the sense that the tension of said spring portion is decreased, thereby creating a relative narrow gap between said busbar 35 (12) and said connection part (24) of said spring portion (14,14’,14’’); wherein said housing (10) comprises a number of wire insertion openings (38,38’,38’’); wherein one or more of said wire insertion opening define a passage (40) into said housing (10), and extending to an associated clamping site (6,6’,6’’) of said busbar assembly (4).
