摘要:
An waterproof terminal for the electrical interconnection of electric conductors comprises a terminal board (5) with four poles housed in a containing body (2) and two cable glands (6,7) coupled with the opposite ends of said containing body (2). Advantageously, the seal of each cable gland (6,7) with a respective abutment surface (9,10) of the containing body (2) is ensured by the fact that on such an abutment surface (9,10) sealing means (15) are overmoulded.

A helical thread mill has a cylindrical stem (2) and cutting portions (3) arranged at one end (4) of the cylindrical stem (2), at least one of the cutting portions (3) including a plurality of thread mill teeth (5), the cutting portions (3) being spaced apart by a plurality of helical flutes (6) developing around an axis (X) of the mill, in which at least one cutting portion (3a) is angularly distant from an adjacent cutting portion (3b) with a pitch (L) having a deviation (S1) comprised between the 5% and the 12% from a nominal pitch.
摘要:
The present invention relates to a safety cable clamp for electric appliances or apparatus in general, including a plurality of safety elements, and comprising a clamp body defining a throughgoing channel for allowing an electric cable to pass therethrough. The body, at an end portion thereof, is clamped to an electric appliance in general and, at the other end portion thereof, defines clamping means for clamping it on the electric cable. The main feature of the invention is that the safety cable clamp comprises moreover, in a single piece with the body, a resiliently yieldable coating, arranged at least at said clamping means.
摘要:
A three-way terminal block construction comprises a central body including a cover and a bottom, said central body defining a plurality of separate seats or recesses adapted to hold therein the respective clamp elements and electrical coupling elements for providing a connection between said clamp elements, thereby causing said clamp elements to be connected by pairs to define electrically connected clamp element pairs, each of said pair being electrically insulated from the other clamp element pairs.
摘要:
A terminal board for the electrical interconnection of electrical conductors (K), comprising a body (2) of electrically insulating material inside which tubular electrical connectors (3) are housed, electrically insulated from one another and configured so as to define open tubular elements and equipped with clamping screws (4). Advantageously, the body (2) is divided into two articulated portions (9,10) articulated together through hinged connection means (6) to allow such a body (2) to pass from an extended configuration to an overlapped configuration in which said articulated portions (9,10) are substantially side-by-side extending on from one another and, respectively, are brought together overlapped one another.
