Abstract
The invention concerns a device with a conductive core (10a) and an insulating sheath (10b) comprising a stripping and retaining slot (18). It comprises: a second stripping and retaining slot (18) substantially parallel to the first and offset relative to the direction of the slots; a push-member (8) designed to receive two electric cables (10) and configured such that each cable should be located transversely opposite a stripping and retaining slot (18), and means (4) for producing a relative displacement between the push-member (8) and the stripping slots (18).
Claims10
An insulation-displacement connecting device for connecting at least two electric cables (10;
- 110) having a conducting core (10a) and an insulating sheath (10b), the device comprising an insulation-displacement and retaining slot (18), further comprising:
- at least one other insulation-displacement and retaining slot (18) known as the second such slot, essentially parallel to the first such slot and offset with respect to a separation direction of the slots;
- a pusher (8;
- 108) intended to accommodate at least two electric cables (10;
- 110) and shaped so that each cable lies transversely facing an insulation-displacement and retaining slot (18);
- means (2, 102) of connection between the slots (18) and the pusher (8, 108) allowing a relative displacement of the slots and of the pusher and guiding the relative displacement;
- and
- means (4;
- 108, 146) for bringing about the relative displacement of the pusher (8;
- 108) and of the insulation-displacement slots (18), wherein
- the two insulation-displacement and retaining slots (18) are made in a blade (6) bent into a U having two parallel branches (14, 16) of different lengths, each slot (18) opening at the free end of each branch,
- the pusher (8) comprises two profiled parts (24;
- 26) extending transversely with respect to the slots and along the separation direction of the slots (18), and
- openings (30, 32) are provided for the passage of each slot and corresponding edges of the two parallel branches through the profiled parts.
The connecting device as claimed in claim 5, characterized in that a screw (4) is provided for displacing the slots (18), this screw being engaged in a metal part (12) connecting the two slots and incapable of translational movement with respect to an insulating casing (2).
The connecting device as claimed in claim 7, characterized in that the slots are carried by parallel curved blades (114;
- 116), in that the pusher (108) is mounted so that it can pivot and has two housings which are essentially transversal with respect to the slots, openings (150) being provided for the passage of the blades (114;
- 116) carrying the slots.
A junction unit, comprising at least one connecting device for connecting at least two electric cables (10;
- 110) having a conducting core (10a) and an insulating sheath (10b), the device comprising an insulation-displacement and retaining slot (18) and further comprising:
- at least one other insulation-displacement and retaining slot (18) known as the second such slot, essentially parallel to the first such slot and offset with respect to a separation direction of the slots;
- a pusher (8;
- 108) intended to accommodate two electric cables (10;
- 110) at least and shaped in such away that each cable lies transversely facing an insulation-displacement and retaining slot (18);
- means (2, 102) of connection between the slots (18) and the pusher (8, 108) allowing a relative displacement of the slots and of the pusher and guiding this displacement;
- and
- means (4;
- 108, 146) for bringing about the relative displacement of the pusher (8;
- 108) and of the insulation-displacement slots (18), wherein
- the two insulation-displacement and retaining slots (18) are made in a blade (6) bent into a U having two parallel branches (14, 16) of different lengths, each slot (18) opening at the free end of each branch,
- the pusher (8) comprises two profiled parts (24;
- 26) extending transversely with respect to the slots and along the separation direction of the slots (18), and
- openings (30, 32) are provided for the passage of each slot and corresponding edges of the two parallel branches through the profiled parts.
