Clamps for male terminals of power sources

A clamp for a male terminal of a power source, the male terminal consisting of a frustoconical body projecting out of a base surface that is part of the power source against which a greatest diameter of the male terminal rests, the clamp comprising:

• at least one ring-shaped first portion, with an open section of its circumference, the at least one ring-shaped first portion having a first diameter such that a predetermined radial clearance exists when the at least one ring-shaped first portion axially fits upon the frustoconical body, the at least one ring-shaped first portion also having two first jaws which axially project out of the circumference of the at least one ring-shaped first portion and are located at ends of the open section of the circumference of the at least one ring-shaped first portion, the first jaws being in opposed, spaced-apart relationship;
• a clamping device which acts on the first jaws and is configured to move the first jaws toward each other to tighten the at least one ring-shaped first portion around the frustoconical body of the male terminal with elimination of the predetermined radial clearance;
• and
• at least one first element hinged to the at least one ring-shaped first portion of the clamp on a side from which the at least one first element is inserted upon the frustoconical body of the male terminal;
• wherein the at least one first element is made of electrically non-conductive material and has a through-hole with a second diameter such that, when the clamp is fitted upon the male terminal, the through-hole establishes radial interference with the frustoconical body of the male terminal at the greatest diameter of the male terminal proximate to the base surface from which the male terminal projects,
• wherein the clamp further comprises:
• a ring-shaped second portion with an open section of its circumference, the ring-shaped second portion lying over the at least one ring-shaped first portion and having a third diameter such that the predetermined radial clearance exists when the at least one ring-shaped first portion and the ring-shaped second portion are axially fitted to the frustoconical body, the ring-shaped second portion of the clamp further having two second jaws that radially project out of the ring-shaped second portion and are located at ends of the open section of the circumference of the ring-shaped second portion, the second jaws being in opposed, spaced-apart relationship and lying over the first jaws of the at least one ring-shaped first portion;
• and
• wherein the clamping device is configured to act on the first jaws of the at least one ring-shaped first portion and on the second jaws of the ring-shaped second portion of the clamp, is configured to move the first jaws of the at least one ring-shaped first portion toward each other to tighten the at least one ring-shaped first portion around the frustoconical body of the male terminal, and is configured to move the second jaws of the ring-shaped second portion toward each other to tighten the ring-shaped second portion around the frustoconical body of the male terminal, with elimination of the predetermined radial clearance.

• wherein the clamp further comprises:
• a power cord for connecting the power source to a power consuming unit, the least one ring-shaped first portion of the clamp being connected to one end of the power cord;
• a conductive basement protruding from the at least one ring-shaped first portion;
• and
• a conductive connecting screw protruding from the conductive basement, the one end of the power cord comprising an eyelet insertable upon the conductive connecting screw.
