Line connector for media lines

A line connector for media lines, comprising a connector piece with at least one junction portion for junction connection to a media line or to an assembly and with a transitional portion contiguous to the junction portion and having a flow duct, comprising in that, at least in the region of the transitional portion, electrical heating means for media line are provided in an arrangement at least partially surrounding the flow duct, the heating means having at least one resistance wire in the arrangement running with an approximately uniform surface distribution at least over the region of the transitional portion, the resistance wire having a meander-like run in order to avoid a coil effect during a current flux, and the resistance wire being embedded into the inner tubular piece of the connector piece.

A line connector for media lines, comprising a connector piece with at least one junction portion for junction connection to a media line or to an assembly and with a transitional portion contiguous to the junction portion and having a flow duct, comprising in that, at least in the region of the transitional portion, electrical heating means for media line are provided in an arrangement at least partially surrounding the flow duct, the connector piece being surrounded by an outer cladding designed for heat insulation with low heat conductivity, the cladding being formed as an outer housing from two symmetrical housing halves which form two half shells of the outer housing.

A line connector for media lines, of the type comprising a connector piece with at least one junction portion for junction connection to a media line or to an assembly and with a transitional portion contiguous to the junction portion and having a flow duct, comprising in that, at least in the region of the transitional portion, electrical heating means for media line are provided in an arrangement at least partially surrounding the flow duct, at least one of the junction portions being designed as a hollow-cylindrical receptacle for directly plugging in the end of the media line, the media line being capable of being fastened in a materially integral manner, in particular by adhesive bonding or welding, or the junction portion consisting, at least in regions, of a material transparent to laser beams, in such a way that the media line can be fastened by means of laser beam welding.

• the line connector consisting of a connector piece with at least one junction portion for junction connection to the media line and with a transitional portion contiguous to the junction portion and having a flow duct comprising in that, at least in a region of the transitional portion, electrical heating means for the media line being provided in an arrangement at least partially surrounding the flow duct, the connector piece being connected to the pipeline via a plug connection, or the connector piece being connected to the pipeline in a materially integral manner by welding or adhesive bonding.

A ready-made media line, comprising a pipeline with a heating conductor arranged on the circumference and a heatable line connector fastened at least to one pipeline end of the media line;

• the line connector consisting of a connector piece with at least one junction portion for junction connection to the media line and with a transitional portion contiguous to the junction portion and having a flow duct comprising in that, at least in the region of the transitional portion, electrical heating means for the media line being provided in an arrangement at least partially surrounding the flow duct, a sealing compound located between the outer housing and the connector piece and in the connection region of the line sheathing within the outer housing.

A ready-made media line, comprising a pipeline with a heating conductor arranged on the circumference and a heatable line connector fastened at least to one pipeline end of the media line;

• the line connector consisting of a connector piece with at least one junction portion for junction connection to the media line and with a transitional portion contiguous to the junction portion and having a flow duct comprising in that, at least in the region of the transitional portion, electrical heating means for the media line are provided in an arrangement at least partially surrounding the flow duct, the electrical heating means includes a resistance wire or resistance wires surrounding the connector body of a line connector and connected electrically to the heating conductor surrounding the media line to form a series connection or to form two series connections.

A ready-made media line, comprising a pipeline with a heating conductor arranged on the circumference and a heatable line connector fastened at least to one pipeline end of the media line;

• the line connector consisting of a connector piece with at least one junction portion for junction connection to the media line and with a transitional portion contiguous to the junction portion and having a flow duct comprising in that, at least in the region of the transitional portion electrical heating means for the media line are provided in an arrangement at least partially surrounding the flow duct, a heating element that is designed as a sheet-like heating element;
• the sheet-like heating element being of a strip-shaped design and being wound either spirally around the pipeline, or so as to overlap at its longitudinal margins around the pipeline, the sheet-like heating element being covered by an outer protective casing, the sheet-like heating element including a carrier, to which are fixed electrical heating conductors that are connected electrically conductively to contact conductors arranged on the carrier.
