Abstract
A device for adjusting the clamping pressure in applicators for clamping terminals onto electrical cables comprising a composite pivot interposed between an actuation hammer and a supporting element to which the tools for clamping the terminal respectively onto the insulation and onto the core of the conductor are slidingly coupled in a mutually parallel arrangement; the thrust of the hammer acts on the heads of the tools, and the pivot is rigidly coupled to the hammer or to the supporting element. The pivot has coaxial threaded regions on which respective wheels are engaged. Screwing/unscrewing of the wheels varies axial distance, with respect to the hammer, of either the tools or only of the insulation clamping tool.

A device for adjusting the clamping pressure in applicators for clamping terminals onto electrical cables provided with core and insulation, comprising:
- tools for clamping a terminal onto the insulation and onto the core of a conductor, respectively;
- an actuation hammer;
- a supporting element to which said tools are rigidly coupled in a parallel arrangement;
- a composite pivot comprising a stem bearing a first and second outer, coaxial, threaded regions, said composite pivot being interposed between said hammer and said supporting element, said hammer acting on respective heads of said tools by pushing, said pivot being rigidly coupled to any of said hammer and said supporting element;
- first and second actuation wheels screwed at said first and second threaded regions, respectively, with the first wheel being engaged on a side of said hammer and the second wheel being engaged on a side of said supporting element, said second wheel acting only on the insulation clamping tool, and wherein said first wheel is actuatable for selectively performing screwing and unscrewing motions on the first threaded region to vary an axial distance of said tools with respect to said hammer, and said second wheel is actuatable for selectively performing screwing and unscrewing motions on the second threaded region for varying an axial distance of only the insulation damping tool.
A device for adjusting the clamping pressure in applicators for clamping terminals onto electrical cables provided with core and insulation, comprising:
- tools for clamping a terminal onto the insulation and onto the core of a conductor, respectively;
- an actuation hammer, a supporting element to which said tools are rigidly coupled in a parallel arrangement;
- a composite pivot which is interposed between said hammer and said supporting element, said hammer acting on respective heads of said tools by pushing, said pivot being rigidly coupled to any of said hammer and said supporting element;
- coaxial threaded regions provided at said pivot;
- respective first and second actuation wheels engaged at said threaded regions, with the first wheel being engaged on a side of said hammer and the second wheel being engaged on a side of said supporting element, said second wheel acting only on the insulation clamping tool;
- a positioning disk arranged between said first and second wheels;
- axial dead holes provided at each one of said first and second wheels;
- corresponding balls accommodated in said dead holes;
- respective springs which are interposed between said balls and bottoms of said dead holes so as to push out said balls, and a series of positioning holes provided at said positioning disk, said balls resting on said positioning disk at said series of holes so as to assume selected stable positions, and said first wheel being movable for screwing and unscrewing motion on a first one of said threaded regions to vary an axial distance of said tools with respect to said hammer, and said second wheel being movable for screwing and unscrewing motion on a second one of said threaded regions for varying an axial distance of only the insulation clamping tool.
