Abstract

A cable connection component for electrically connecting a multi-core cable has a union nut with an internal thread, and a splicing part made of insulating material having a plurality of incisions for separating the cores of the cable. Upon screwing the union nut onto a connection body, the core insulation of the core ends inserted into the splice part are severed by insulation displacement terminations that are arranged in the connection body and are immerge into the incisions in the splice part, and the conductors of the cores are contacted. The splice part has a cable receiving part and a core guiding part, the core guiding part having at least two core receptacles, and each core receptacle having at least two retaining elements and at least two clamp elements forming a clamping gap. The retaining elements and the clamp elements do not overlap in the core insertion direction.

Claims

1. A cable connection component for electrically connecting a multi-core cable, comprising:

a union nut having an internal thread,

a splicing part made of an insulating material and having a plurality of incisions shaped for separating cores of the cable when the union nut is screwed onto a connection body having an external thread corresponding to the internal thread of the union nut,

wherein the splicing part has a cable-receiving part and a core-guiding part, the core-guiding part having at least two core receptacles, each core receptacle has at least two retaining elements and at least two clamp elements which together form a clamping gap,

wherein, in a core insertion direction, first the retaining elements are arranged, and the clamp elements are arranged behind them, and

wherein distances of outer surfaces and inner surfaces of the clamp elements and the retaining elements with respect to a longitudinal axis of the core-guiding part are such that the retaining elements and the clamp elements are arranged do not overlap each other in the core insertion direction.

2. The cable connection component according to claim 1, wherein the distance between the outer surfaces of the clamp elements and the longitudinal axis of the core-guiding part is less than or equal to the distance between the inner surfaces of the retaining elements and the longitudinal axis.

3. The cable connection component according to claim 2, wherein each of the core receptacles has a contact area following the clamp elements in the core insertion direction and wherein the distance between the outer surfaces of the contact area and the longitudinal axis is less than or equal to the distance between the inner surfaces of the clamp elements and the longitudinal axis.

4. The cable connection component according to claim 1, wherein at least one of the retaining elements and the clamp elements and the clamp elements and the contact area are physically separated from one another in the longitudinal direction of the core-guiding part.

5. The cable connection component according to claim 1, wherein the inner surfaces of two clamp elements and of two adjacent core receptacles lie in a common plane and wherein the common plane is arranged parallel to the longitudinal axis of the core-guiding part.

6. The cable connection component according to claim 5, wherein the outer surfaces of the two clamp elements and the inner surfaces of the two retaining elements of two neighboring core receptacles are arranged in a common plane.

7. The cable connection component according to claim 1, wherein at least one of the inner surfaces of the retaining elements are arranged on a common first radius and the inner surfaces of the clamp elements are arranged on a common second radius about the longitudinal axis of the core-guiding part.

8. The cable connection component according to claim 7, wherein the inner surfaces of the retaining elements and the outer surfaces of the clamp elements are arranged on the common first radius.

9. The cable connection component according to claim 1, wherein the core receptacles are arranged asymmetrically on the circumference of the core-guiding part.

10. The cable connection component according to claim 1, wherein the cable-receiving part has several latching arms on a side facing the core-guiding part and wherein the core-guiding part has, on a side facing the cable-receiving part, several inwardly projecting latching catches or catch recesses corresponding to the latching arms, so that the core-guiding part is able to latch with the cable-receiving part.
