Definitions
- the present invention relates to an open protection tube, especially for the mechanical and thermal protection of electrical conductors and other components in automobiles.
- protection tubes are used to protect electrical conductors and other components, especially the automobile field.
- the protection tubes must have a high mechanical and thermal resistance, as they are used in high temperature areas and are subject to abrasion.
- these protection tubes must also include noise insulation characteristics, since it would be unacceptable for these protection tubes to produce noise when used in cars.
- protection tubes formed by a series of layers, for example a first layer formed by a plurality of threads of plastic or mineral material woven together and a second layer of aluminum foil on said first layer. These protection tubes are used to achieve good electromagnetic and thermal insulation.
- the open protection tube of the present invention comprises a first layer formed by a plurality of threads of plastic material woven together and a second layer of aluminum foil, and is characterized by the fact that said aluminum foil layer is formed by a film of plastic material and an aluminum film, said film of plastic material being welded to said first layer.
- This protection tube is opened in the longitudinal direction, greatly facilitating assembly.
- said plastic material film is polyester.
- the threads that form said first layer are polyester or polyester and polyamide.
- the aluminum film may be located in the inner part of the tube.
- protection tube of the present invention excellent electromagnetic and thermal insulation is achieved, withstanding high temperatures, and excellent adhesion between the first and second layers and a great ease of assembly.
- Figure 1 is a cross-sectional view of the protection tube of the present invention
- Figure 2 is a graph in which the test result is shown to demonstrate the electromagnetic isolation of the protection tube of the present invention. Description of a preferred embodiment
- the protection tube of the present invention is formed by two layers: - a first layer 1 formed by a plurality of polyester or polyester and polyamide yarns woven together; and a second layer of foil 2 on said first layer 1.
- the aluminum foil layer 2 is formed by a polyester film 3 and an aluminum film 4, said polyester film 3 being welded to said first layer 1.
- the thickness of the polyester film 3 can be
- the thickness of the aluminum film 4 can be from 9 to 25 microns, with a total weight of the layer of aluminum foil 2 of 2.6 g / m.
- the welding of the aluminum foil layer 2 on said first layer 1 is preferably carried out at a temperature between 240 ° C and 540 ° C, said welding being carried out continuously at a speed between 1 and 20 m / min.
- Said first layer 1 has, for example for a width of 50 mm, a weight of 17.26 g / m and a thickness of 1.0 mm ⁇ 0.3 mm.
- the tube of the present invention for a diameter of 7mm, can have a weight of 19.86 g / m and a thickness of 1.0 mm ⁇ 0.3 mm.
- the order of the layers can be reversed by placing the aluminum inside and the fabric outside.
- a two meter long wire, connected to the generator acts as an emitter of electromagnetic waves.
- a measurement of the received power is made.
- the 15 cm antenna is screened with the test tube (sample) and the received power is measured again.
- the difference between both powers is a measure of the shielding of the sample. It must be taken into account that the majority of measurements are of minimum screening, and that the actual screening is always greater than that of the graphs. This is a consequence of the fact that the measurement with the shielded antenna almost always gives zero received power.
- the main objective of this test is to study the behavior of the protection tube under an external heat source.
- Radiant heat source 400 ° C Distance: 35 mm below the heat source
- Dimensions of the hot box 420 mm x 420 mm x 245 mm
- thermocouples
- thermocouple Position of the thermocouple touching the external surface of the ceramic cylinder, at the midpoint of the length (15 cm) and measuring the temperature inside the protection tube.
- thermocouple for the measurements of the ambient temperature in the hot box.
- Delta T is calculated as the difference between the T of the emitter and the T inside the tube:
