Spring part for retaining electric wires and terminal block comprising said spring part.

摘要

Spring part for retaining wires (1,1a) inside electric terminal blocks (300;1300), comprising a conductor body (110) substantially in the form of an overturned "U", with one arm (111) substantially parallel to the vertical direction (Z-Z) and one arm (112;1112) forming an acute angle with the vertical arm (111) and having a free end (112a;1112a), the two arms (111,112;1112) being connected together by a convex curved section (113) able to produce the resilient reaction of the inclined arm (112;1112) with respect to the vertical arm (111), the vertical arm (111) being joined to a U-shaped base (120) comprising a first vertical arm (121) for connection to the vertical arm (111) of the body (110), a second vertical arm (122) with a free end (122a) and a longitudinal section (123) connecting together the two vertical arms, said base (120) being designed for stable engagement with a conducting part (200) of the electric terminal block (300;1300).
