Abstract

The invention relates to a contact-making apparatus for establishing electrical contact between a conductor or a plurality of conductors of a cable which is to be connected and a plug connector, comprising an insulating body which can be inserted into a chamber of a plug connector housing which is provided for this purpose, and at least one pressure piece which is suitable for receiving at least one conductor, wherein the at least one pressure piece is connected to the insulating body in a pivotable and articulated manner, and wherein the insulating body comprises at least one recess which in turn contains at least one insulation-displacement terminal, and wherein the pressure piece can be recessed in the at least one recess in the insulating body, and therefore the insulation-displacement terminal makes electrical contact with the end portion of the conductor.

Claims

1. A contacting device for the electric contacting of one conductor or several conductors of a cable to be connected to a plug-in connector, comprising

an insulating body (1), which can be inserted into a chamber (30) of a plug-in connector housing (40) provided for this purpose,

at least one pressure part (3), which is suitable to accept at least one conductor, with at least one pressure part (3) being pivotally linked to the insulating body (1),

and at least one contacting means (10) for an electric contacting of an end section of a conductor,

with the insulating body (1) comprising at least one recess (2), which includes said at least one contacting means (10), and wherein said at least one pressure part is pivotally linked to said insulating body adjacent said at least one recess,

wherein

the pressure part (3) can be pivotally moved by insertion of the insulating body (1) into the chamber (30) so as to sink the pressure part in at least one recess (2) of the insulating body (1),

so that the end section of a conductor that is accepted in the pressure part can be electrically contacted by the contacting means (10).

2. A contacting device according to claim 1,

characterized in that

the contacting means is an insulation displacement termination (10).

3. A contacting device according to claim 1,

characterized in that

the insulating body (1) comprises grooves (4), into which bars (31) can be inserted, extending inside the chamber (30) of the plug-in connector housing, with the bars (31) mutually shielding in an electromagnetically fashion pairs of conductors of a cable to be connected.

4. A contacting device according to claim 1,

characterized in that

the pressure part (3) comprises a cable core accept (3a) and a pivotal arm (3b).

5. A contacting device according to claim 1,

characterized in that

the insulating body (1) is cylindrical.

6. A contacting device according to claim 1,

characterized in that

the insulating body (1) is box-shaped.

7. A contacting device according to claim 1,

characterized in that

at least one pressure part (3) is aligned in the axial direction of the insulating body (1).

8. A contacting device according to claim 1,

characterized in that

at least one pressure part (3) can be latched via fastening pins (8) in a first latching position in the insulating body (1).

9. A contacting device according to claim 8,

characterized in that

in a second latching position the pressure part (3) can be latched entirely inside the insulating body (1).

10. A connecting device for electrically connecting conductors of a cable to a plug-in connector, said plug-in connector including a plug-in connector housing having at least one axially extending chamber therein, said connecting device comprising,

an axially extending insulating body insertable in an axial direction into a chamber of a plug-in connector housing, said insulating body including at least one axially extending recess that includes an electrical contact for electrically contacting a cable conductor, said insulating body further including at least one elongated pressure part having one end including an opening for receiving a cable conductor and an opposite end having a pivotable connection for pivotally connecting said pressure part to said insulating body, said pressure part including a pivot arm extending between said one end and said opposite end, each said pressure part overlying a recess, said pressure part pivotal from an angled position above said recess into an axially oriented position within said recess and into engagement with said electrical contact to enable a cable conductor that is received within the pressure part to engage the electrical contact, wherein said pivot arm is engageable with the plug-in connector housing to pivot the pressure arm from an angled position above said recess into an axially oriented position within said recess as said insulating body is inserted into the chamber of the plug-in connector housing.

11. The connecting device of claim 10, wherein said electrical contact comprises an insulation displacement termination means for severing an insulation jacket of a cable conductor when said pivot part is inserted within said recess of the insulating body.

12. The connecting device of claim 11, wherein said insulating body includes grooves for aligning the insulating body with said chamber of the plug-in connector housing.

13. The connecting device of claim 11, wherein said pressure part includes a fastening pin for latching said pressure part in a first angled position and for latching said pressure part in a second axially oriented position entirely within said recess.
