Abstract
A cable connection unit comprises a pile of insulating plates carrying preformed conducting strips. A first end of each strip is connected to or forms a lead-in or lead-out terminal, and a second end is bent in an orifice traversing the pile. Plug modules plugged in one face of the pile have lead-in and lead-out pins contacting the bent second ends of the strips and a grounding pin contacting a grounding grid placed on the opposite face of the pile. The modules have fuses connecting their lead-in and lead-out pins and lightning protectors between these pins and the grounding pins. When a module is not plugged in, the bent second end of the corresponding lead-in terminal comes to contact the grounding grid.
Claims17
A connection unit for cables, in particular telecommunications cables, comprising:
- a pile of insulating support plates having first and second outer faces;
- means defining a plurality of orifices traversing said pile of plates from said first to said second outer face;
- at least some of said plates carrying at least one preformed conducting element, said conducting elements being disposed in pairs consisting of a first conducting element having a first end connected to or forming a lead-in terminal and a bent second end disposed in a first of said orifices, and a second conducting element having a first end connected to or forming a lead-out terminal and a bent second end disposed in a second of said orifices;
- said lead-in terminals being grouped together on one of said first and second faces of said pile and said lead-out terminals also being grouped together on one of said first and second faces of said pile, for connection of lines of a cable;
- a grounding circuit disposed adjacent said first face of said pile;
- said bent second ends of said first conducting elements being bent towards said first face and being dimensioned and prestressed to tend to come into contact with corresponding parts of said grounding circuit;
- each pair of said first and second orifices receiving said second ends of a pair of first and second conducting elements being associated with a third said orifice;
- and at least one plug module comprising means for electrically connecting and protecting a pair of said lead-in and lead-out terminals, said module comprising first, second and third parallel plug pins pluggable in said second face of said pile in associated first, second and third orifices whereby said first plug pin contacts said bent second end of said first conducting element and holds it out of contact with said grounding circuit, said second plug pin contacts said bent second end of said second conducting element and said third plug pin contacts a corresponding part of said grounding circuit, said module comprising means for electrically connecting said first and second plug pins and a lightning protector connected between said first and third plug pins.
A connection unit for cables, in particular telecommunications cables, for connecting lines of the cable to ground via lightning protectors, comprising:
- a pile of insulating support plates having first and second outer faces;
- means defining a plurality of orifices traversing said pile of plates from said first to said second outer face;
- at least some of said plates carrying at least one preformed conducting element having a first end connected to or forming lead-in and lead-out terminals for connection of a line of a cable, and a bent second end disposed in a first of said orifices;
- said lead-in and lead-out terminals being grouped together on respective faces of said pile and each being formed of a single piece;
- a grounding circuit disposed adjacent said first face of said pile;
- each of said first orifices receiving said second bent end of a conducting element being associated with a second said orifice;
- and at least one plug comprising first and second parallel plug ping pluggable in said second face of said pile in associated first and second orifices whereby said first plug pin contacts said bent second end of said first conducting element and said second plug pin contacts a corresponding part of said grounding circuit, said module comprising a lightning protector connected between said first and second plug pins (FIG. 5).
A connection unit for cables, in particular telecommunications cables, comprising:
- a pile of insulating support plates having first and second outer faces;
- means defining a plurality of orifices traversing said pile of plates from said first to said second outer face;
- and
- at least some of said plates carrying at least one preformed conducting element, said conducting elements being disposed in pairs consisting of a first conducting element having a first end connected to or forming a lead-in terminal and a bent second end disposed in a first of said orifice, and a second conducting element having a first end connected to or forming a lead-out terminal and a bent second end disposed in a second of said orifices;
- said lead-in terminals being grouped together on one of said first and second faces of said pile and said lead-out terminals also being grouped together on one of said first and second faces of said pile, for connection of lines of a cable.
