Cable guide

1. Cable guide, consisting of links, connected to each other in articulated fashion, capable of angling in at least two directions relative to each other, and open on a face end, which are arranged behind each other in a longitudinal direction of the cable guide and form at least one guide channel by means of external guide elements, wherein a joint is located between two of the connected links within the cable guide, and wherein each of the two connected links has a corresponding connecting element having first and second connecting components, characterized in that the first connecting component of the connecting element is a fork-shaped design having two legs a distance apart from each other and each leg having an opening therein, and the second connecting component has a first seat having a spherical boundary surface and a joint element having an opening and a spherical outer boundary surface adapted to the spherical boundary surface of the first seat, wherein the joint element is mounted in the first seat in moveable fashion, and the second component having the joint element located therein can be positioned between the two legs of the first component in such a way that the opening in the joint element is aligned with the opening provided in each of the two legs of the first connecting component, such that a pin is insertable into a second seat formed by the openings in the two legs of the first component and the opening in the joint element of the second component, and is mounted in the second seat.

2. Cable guide according to claim 1 , characterized in that the connecting elements of each of the two connected links are each on a mount that is connected to a shell section of the link.

3. Cable guide according to claim 2 , characterized in that the each mount is designed as a web that extends essentially radially.

4. Cable guide according to claim 2 , characterized in that each mount extends in a direction running essentially parallel to the pin.

5. Cable guide according to claim 2 , characterized in that each mount has two ends and connected to the shell section at both of the ends.

6. Cable guide according to claim 1 , characterized in that a first end of the pin is provided with elastically displaceable, snap-in projections that, in a mounted position of the pin, reach behind a stop face and protect the position of the pin from longitudinal displacement.

7. Cable guide according to claim 6 , characterized in that the snap-in projections are manufactured with the remainder of the pin from plastic in one piece.

8. Cable guide according to claim 6 , characterized in that the snap-in projections are located on free ends of elastically deformable webs which extend essentially parallel to a longitudinal axis of the pin and are integrally connected to the pin in such a way that the snap-in projections can be elastically displaced into an active position and an inactive position.

9. Cable guide according to claim 8 , characterized in that the first component of the connecting element provides a seat for the snap-in projections into which the snap-in projections snap in an active, final position of the pin under an effect of an elastic restoring force of the webs.

10. Cable guide according to claim 9 , characterized in that the snap-in seat for the snap-in projections is designed, and dimensioned in terms of depth, in such a way that the snap-in projections are disengaged from the snap-in seat under an effect of a force acting on the pin in a longitudinal direction of the pin, and the webs bearing snap-in projections are deformed in the process.

11. Cable guide according to claim 1 , characterized in that the opening in at least one of the two legs of the first connecting component has, at an end facing away from the other leg, a wider cross-section that transitions, via a shoulder, into a section of the opening with a smaller cross-section.

12. Cable guide according to claim 11 , characterized in that the wider cross-section of the opening in the one leg has an approximately elliptical cross-sectional shape, such that a shorter axis of the elliptical cross-sectional shape essentially corresponds to a diameter of the opening with the smaller cross-section in the leg, and accommodates the pin, and a longer axis of the elliptical cross-sectional shape, running perpendicular to the shorter axis of the elliptical cross-sectional shape, is larger than the diameter of the opening with the smaller cross-section, and snap-in projections are located around circumferential areas at an end of the pin in such a way that, in a mounted position of the pin, the snap-in projections are assigned to the section of the opening with a wider cross-section.

13. Cable guide according to claim 1 , characterized in that an arm forms the first seat and at least areas of the arm forming the first seat, and at least areas of the joint element mounted in the first seat in moveable fashion, are made of plastic.

14. Cable guide according to claim 1 , characterized in that each of the connected links has a shell section and the shell sections are provided with openings for passing through tools for manipulating the pin.

15. Cable guide according to claim 14 , characterized in that the openings in the shell sections are circular openings arranged in such a way that the openings lie essentially on a longitudinal axis of the pin.
