Abstract
The invention relates to a two-conductor system for earth boring rod sections for forming a boring string for an earth boring device, wherein the two-conductor system has an insulated composite made of a first conductor and a second conductor, and the first and second conductors are each exposed at one end from the composite in a connection direction, and at least a section of an exposed end of one of the conductors is surrounded on the circumference by an inner and an outer insulation sleeve.
Claims6
A two-conductor system for earth boring rod sections for forming a boring string for an earth boring device, wherein the two-conductor system comprising:
- an insulated composite made of a first conductor and a second conductor, and the first and second conductors are exposed at one end of the first conductor and at one end of the second conductor from the insulated composite in a connection direction,
- wherein an electrical conduction path is formed for at least the first and second conductors, the electrical conduction path extends away from the exposed at the one end of the first conductor via an insulation surrounding the first conductor and/or the insulated composite against the connection direction, and
- the electrical conduction path leads past the one end of the first conductor in an insulated manner in the connection direction,
- wherein the exposed at the one end of the first conductor is contacted by an electrically conductive ring abutting the exposed at the one end of the first conductor, by which the insulation surrounding the first conductor and/or the insulated composite is sealed by pressing an insulating sealing piece onto the insulation surrounding of the first conductor and/or the composite.
