Abstract: A fastening assembly for electric and/or electronic devices that can be built in includes a frame (2) and claws (3) adapted to secure the frame (2) to the wall or box where it is built-in, showing at least two claws (3) of which at least one is flexible and independent from the frame (2) and can be joined to the frame (2) by temporarily deforming the claw (3) generating when joined to the frame (2) at least three unaligned bearing points between the claw (3) and the frame (2). The frame (2) includes at least one hollow (21) and at least two supporting points (20), and the claw (3) two bearing points (30), can be introduced in the hollow (21) of the frame (2) and when the claw (3) is released, the the bearing points (30) or clipping flanges are coincident with the supporting points or mortises (20) of the frame (2).

Abstract: An insulation-displacement connector including two cutting and connecting blades, each one provided with a section for inserting and centering of a cable, a cutting edge which extends from the section for centering and insertion, a base, and an arm for joining each blade to the base; where the cutting edges are inclined along the entire extension of the edges such that they cross one another, and where the cutting and connecting blades are not joined together at an end of the blades opposite to the joining end of the sections, but rather are joined to the arms such that the blades may be separated from one another according to a transverse direction.

Abstract: Frame and connection base assembly for flush mounting mechanisms, and related coupling method, wherein the frame includes an opening delimited by a guiding and fitting perimeter of the connection base, which includes a connection body, which has first and second portions of different sections such that in the transition between both, bearing surfaces are defined that rest on the frame around the guide and fitting perimeter, such that the connection base can rotate with respect to the frame according to a rotation that has the direction normal to the plane of the frame.

Abstract: The electrical contact for electrical cables comprises a base (1) and at least one cutting and connection element (2), the or each cutting and connection element (2) defining an initial cutting edge (3) and a cutting and connection portion (4) and is characterized in that said initial cutting edge (3) is closer to the base (1) than said cutting and connection portion (4).
