Abstract

A cable assembly (100) is provided having a first cable (20) having a first conductor (22), a second cable (40) having a second conductor (42) and an electrically conducting joining element (60). The joining element (60) comprises a first threaded end section (61) and a second threaded end section (62) opposite of the first end section (61. The first threaded end section (61) is connected to the first conductor (22). The second threaded end section (62) is connected to the second conductor (42). The present invention also relates to a method for joining a first cable (20) having a first conductor (22) and a second cable (40) having a second conductor (42).

First claim

1 . Cable assembly comprising:
a first cable having a first conductor, a second cable having a second conductor and an electrically conducting joining element; wherein the joining element comprises a first threaded end section and a second threaded end section opposite of the first end section; wherein the first threaded end section is connected to the first conductor; wherein the second threaded end section is connected to the second conductor wherein the first threaded end section is connected to an opening provided in the first conductor; and wherein the second threaded end section is connected to an opening provided in the second conductor.

2 . The cable assembly according to claim 1 , wherein the first threaded end section and the second threaded end section are screwed into the respective cable conductors when the joining element is rotated in a first direction relative to both the first and second conductors.

3 . The cable assembly according to claim 1 , wherein the joining element comprises an intermediate section axially between the first threaded end section and the second threaded end section.

4 . The cable assembly according to claim 1 , wherein the outermost layer of the first conductor comprises a first step profile;
the outermost layer of the second conductor comprises a second step profile, wherein the cable assembly further comprises a sleeve section surrounding the first step profile and the second step profile.

5 . The cable assembly according to claim 4 , wherein the sleeve section is connected to the intermediate section of the joining element.

6 . The cable assembly according to claim 1 , wherein the intermediate section of the joining element has a diameter equal to the diameter of one of the conductors.

7 . The cable assembly according to claim 7 , wherein the sleeve section comprises a tool interface for rotating the joining element relative to both of the conductors.

8 . The cable assembly according to claim 1 , wherein the first and second conductors are connected to each other directly and/or via the joining element by means of additional fastening means, such as mechanical bonding, an adhesive or welding.

9 . A method for joining a first cable having a first conductor and a second cable having a second conductor; wherein the method comprises the steps of:
providing an electrically conducting joining element comprising a first threaded end section and a second threaded end section opposite of the first end section; screwing the first threaded end section into the first conductor; screwing the second threaded end section into the second conductor.
wherein the method further comprises the steps of:
providing a first opening in the first conductor;
providing a second opening in the second conductor;

wherein the screwing steps comprises:
screwing the first threaded end section into the first opening; and
screwing the second threaded end section into the second opening.

10 . The method according to claim 9 , wherein the steps of screwing the first threaded end section into the first conductor and screwing the second threaded end section into the second conductor comprises the step of:
rotating the joining element in a first direction relative to both the first and second cable conductors.

11 . The method according to claim 9 , wherein the method further comprises the steps of:
providing the joining element with an intermediate section axially between the first threaded end section and the second threaded end section, the intermediate section comprising a tool interface.

12 . The method according to claim 9 , wherein the method further comprises the steps of:
providing the outermost layer of the first conductor with a first step profile; providing the outermost layer of the second conductor with a second step profile; providing a sleeve section circumferentially outside of the first step profile and the second step profile.

13 . The method according to claim 12 , wherein the method comprises the steps of:
providing the sleeve section as a part of the joining element by connecting the sleeve section to the intermediate section.
