Definitions
- Plastic hose especially pneumatic hose
- the invention relates to a plastic hose, in particular a pneumatic hose, with at least two electrical lines extending along the hose body.
- pneumatic devices and devices in particular also require electrical connections for the transmission of electrical control signals, sensor signals and supply voltages. In individual cases, this can lead to a large number of lines, hoses and cables making the installation, maintenance and repair of such devices complex, confusing and expensive. Corresponding problems also occur with hydraulic devices and devices and other devices in which both fluids and electrical signals have to be transmitted.
- An object of the present invention is to provide a plastic hose for the transmission of fluidic media with additional electrical conductors, which, with simple and inexpensive production, enables easier contacting with very good flexibility.
- the lines are designed as strips of a metallized braid made of plastic material or natural fibers, which are attached to the hose body at a distance from one another.
- the metallized braid made of plastic material or natural fibers is extremely flexible, which means that the entire plastic hose is very flexible and durable, since the strip-shaped braid is extremely tear-resistant and practically follows every movement of the hose. Breaking this network is almost impossible. Very small bending radii of the plastic hose are possible without the conductivity being impaired by upsetting or stretching.
- the width of the strip-shaped braid can extend over a large part of the circumference, so that good electrical conductivity is achieved even when the braid thickness is desired and the bursting pressure is increased at the same time. The width also allows easy contacting, both radially (circumferentially) and axially (on the front).
- a particularly good flexibility with regard to the compression or stretching of the braid that occurs during bending is achieved in that the braid has fiber arrangements that run essentially at right angles to one another.
- the fibers of one of the fiber arrangements preferably run in the longitudinal direction of the respective strip.
- the strips can run in the longitudinal direction of the plastic tube or can be wound around it.
- the distance between the strips is chosen to be very small in order to achieve the greatest possible conductivity, preferably less than 10% of the strip width.
- the plastic hose is expediently provided with a tubular protective sheath made of plastic material and enclosing the strips.
- the strips are expediently at least partially glued, welded or extruded to the tube body or to a protective layer surrounding it. Extruding has the particular advantage that the plastic tube can be produced in one operation during extrusion.
- FIG. 1 An embodiment of the invention is shown in the drawing and explained in more detail in the following description.
- the single figure shows a perspective view of an end region of a plastic tube with the protective cover removed at the end as an exemplary embodiment of the invention.
- the plastic hose 10 shown in perspective in the single exemplary embodiment can be used, for example, as a pneumatic hose, hydraulic hose or for the transfer of another liquid or gaseous medium.
- electrical signals for example sensor signals, control signals or supply voltages, can be transmitted via this plastic tube by means of two strips 11, 12, which consist of a metallized mesh made of plastic material or natural fibers.
- the metallized braid of the two strips 11, 12 has two fiber arrangements which run essentially at right angles to one another, the fibers of a fiber arrangement running in the longitudinal direction of the respective strip 11, 12, that is to say in the longitudinal direction of the plastic tube 10.
- the two strips 11, 12 are attached to the outside of a hose body 13 made of plastic, which consists of a plastic material customary for such hoses, for example polyurethane, polyamide, polyethylene, polypropylene, PTFE or PVC. If the braid of the strips 11, 12 does not consist of natural fibers, one of the aforementioned plastic materials can be used for this, the braid being metallized in any case to achieve the required electrical conductivity.
- two strips 11, 12 run parallel to one another in the longitudinal direction of the plastic hose 10 and are at a short distance from one another, which brings about the required electrical separation.
- This distance can be very small, for example less than 10% of the width of a strip 11 or 12.
- the strips 11, 12 are made as wide as possible in order to achieve the greatest possible electrical conductivity.
- the invention is of course not limited to two strips 11, 12, rather the number of strips can also be larger in accordance with the number of desired electrical lines, the width of the strips correspondingly decreasing as the number increases.
- the strips 11, 12 can be glued or welded to the tube body 13, but they can also be extruded when the tube body 13 is extruded, which should represent the cheapest manufacturing method. If necessary, an intermediate or protective layer can be arranged between the hose body 13 and the stiffeners 11, 12. In this case, the strips 11, 12 are of course attached to this protective layer.
- the strips 11, 12 can also be attached to the tube body 13 in a helical shape.
- the tubular body 13 provided with the strips 11, 12 is additionally surrounded by a tubular protective cover 14 made of non-conductive plastic material. This can be applied during extrusion or afterwards.
- the thickness of the conductive braid can be very small and, for example, only be of the order of 1/10 mm. As a result, the overall diameter of the plastic hose 10 is changed almost completely compared to conventional hoses, and very small outer diameters can be realized.
- the electrical contacting can be carried out very easily and can be carried out from the circumference or at the end, for example by means of a screw connection provided with corresponding contacts.
- the protective cover 14 can either be removed at the contact point, or contact tips are used which come into contact with the strips 11, 12 through the protective cover 14.
- Such conductive strips can also be arranged in several, for example two, layers one above the other, with electrically insulating intermediate layers being required for mutual insulation. Each layer can have one or more strips. If there is only one strip per layer, it can also be tubular. If there are several strips per layer, they can be radially aligned one above the other.
