Terminal block for connecting electric wires comprising an insulating body and a conducting part housed inside it and associated with means for retaining the free end of the electric wire, said conducting part having a U-shaped form.

Terminal block with U-shaped conducting part for connecting electric wires

A terminal block for connecting electric wires using a removable contact, such as a fuse, with flat pins, includes an insulating body and two conducting elements housed inside the body. Associated with respective terminals for retaining the free end of a respective electric wire, the conducting elements including, at an end opposite to the end for retaining the wire, a resilient clamp which is open on one side for insertion, retention and electric contact with the respective flat pin of the movable contact.

The block has a straight conductor strip (3) including a lateral step (51) provided with a socket (54) for receiving a wiring end of an electrical conductor e.g. electrical cable, where the socket belongs to a strip`s portion. An electric cable introducing pipe (32) is opened in the socket. The portion has an adjusting step (52) with a stop whose end is connected to an end of the step (51). A spring blade (4) has a curved section (60) connecting long and small straight handles (58, 59), where a small handle`s end portion holds the stop of the strip from a side opposite to the handle (58).

Terminal block for electrical conductors

Spring part for retaining wires inside electric terminal blocks, comprising a conductor body substantially in the form of an overturned “U”, with a vertical arm substantially parallel to the vertical direction and a second arm forming an acute angle with the vertical arm and having a free end. The two arms being connected together by a convex curved section adapted to produce a resilient reaction of the second arm with respect to the vertical arm. The vertical arm can be joined to a U-shaped base formed from a first vertical arm, connected to the vertical arm of the conductor body, a second vertical arm having a free end and a longitudinal section connecting the two vertical arms. The U-shaped base being designed for stable engagement with a conducting part of the electric terminal block.

Electrical connection jumper, in particular for terminal blocks of switchboards, comprising a conducting body extending in the longitudinal direction and a plurality of connector elements for electrical connection, which extend in the transverse direction from said conducting body, and an insulating body, integral with said conducting body, said insulating body comprising a longitudinally extending gripping part and pairs of lugs which extend therefrom in a substantially transverse direction and are able to contain partially said conducting body.

Insulated jumper in particular for terminal blocks of switchboards

An electric modular terminal block , especially a through-terminal or ground terminal, has a housing (5) made of an insulating material and having two conductor connection elements (6) and at least one power line (7) arranged in the housing and electrically connecting the conductor connection elements (6). The terminal housing (6) has a recess on the lower face of the terminal housing facing the mounting rail (2) for insertion of a metal ground connecting element (11). An independent claim is included for a metallic ground connection element.
