Abstract

Fluid hose with a fluid guide and electrical lines, characterized in that in a plastic hose at least one serving for fluid guide flexible inner capillary is arranged, which is covered by a mesh of insulated wires.

Description

The invention relates to a fluid hose with at least one flexible inner capillary and electrical lines serving for fluid guidance.

Such a fluid tube allows both the transmission of fluid and electrical signals. Since it can be dispensed with the use of separate electrical cable, resulting in a low-cost and low-maintenance design. The fluid tube contains in its interior electrical lines for transmitting electrical signals.

In particular, pneumatic devices and devices require in addition to pneumatic hose connections and electrical connections for the transmission of electrical control signals, sensor signals and supply voltages. In individual cases, this can mean that a large number of lines, hoses and cables make the installation, maintenance and repair of such devices complicated, confusing and expensive. Corresponding problems also occur in hydraulic devices and devices and other equipment in which both fluids and electrical signals must be transmitted.

By a mesh-like configuration, a high flexibility for the electrical conductor can be achieved, so that the fluid hose can be easily bent.

Out DE 197 24 038 C1 An electrically conductive hose protrudes, in whose wall carbon fibers are integrated in order to obtain an electrical conductivity, which counteracts a possible electrical charge.

Furthermore, it is off DE 20 119 352 U1 a fluid tube known, in whose wall at least one strand-shaped signal conductor extends, which opens at the end face on the fluid tube.

The invention has for its object to provide a plastic tube for the transmission of fluidic media with additional electrical conductors, which allows simple and cost-effective production easy contact with very good flexibility.

The object is achieved with a hose having the features specified in claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

In the case of the fluid tube, the fluid guidance takes place in a tube which contains a flexible inner capillary, which is enveloped by a mesh of insulated wires.

An advantageous embodiment provides that a plurality of inner capillaries are present, which are wrapped individually or together by the braid of insulated wires.

Furthermore, it is possible that the inner capillaries are intertwined and / or that the inner conductors are braided by the inner capillaries.

To increase the flexibility, it is possible that the inner capillaries have partial areas or very wavy walls.

For special labeling, the plastic tube can be made multi-colored.

The invention will be explained in more detail below with reference to an embodiment.

In the accompanying drawings show:

1 a perspective view of a hose end,

2 a view of a hose end of an embodiment with an inner capillary,

3 a view of a hose end of a version with three inner capillaries,

4 a view of a hose end of an embodiment with electrical lines within the inner capillary,
and

5 a plan view of a wavy inner capillary.

The in 1 plastic hose shown in perspective can be used for example as a pneumatic hose, hydraulic hose or for the transfer of any other liquid or gaseous medium. In addition, electrical signals, for example sensor signals, control signals or supply voltages can be transmitted via this plastic tube.

The transmission of the electrical signals is preferably carried out with a metallized braid, which may be wrapped with plastic material or natural fibers.

2 shows the hose end of a design with only one inner capillary, which is covered by a metallic braid.

Out 3 shows a version that contains several inner capillary. An example with three inner capillaries is shown.

At the in 4 The hose design shown, the electrical cables are located inside the inner capillary.

In 5 an embodiment is shown in which the inner capillary has a wavy surface. Thus, a high flexibility of the capillary and thus the entire tube can be achieved.
