Definitions
- the invention relates to a device for producing a seal between a first part and a second part, in particular a first housing part and a second housing part. Furthermore, it relates to a device for receiving an electrical circuit and / or which comprises electrical switching means and a method for producing such a seal.
- Housing parts e.g. of electronic devices often comprise a plurality of parts which are detachably or non-detachably connected and sealed together, e.g. by screwing, riveting, latching or gluing, in particular involving a flexible sealing element, e.g. a sealing ring, is achieved.
- these parts often consist of plastics and in their manufacture, for example, due to a manufacturing process tolerances, e.g. in terms of dimensions, and / or shape deviations, which, at least for higher quality products, by means of cost and time-intensive tuning of the parts reduced or avoided each other.
- additional elements e.g.
- sealing elements are also matched to the parts, stockpiled or if necessary, specially made to fit. Furthermore, if, for example, gaskets are not firmly connected to at least one part, they may be lost and / or, if used repeatedly, these elements may be subject to wear, which may lead to their uselessness.
- EP 0 302 618 discloses a device for producing a sealed connection of two or more parts of a heat exchanger, which comprises a ring-shaped or tubular shaped memory effect (SME) material based on copper, zinc, aluminum and titanium / nickel (NiTi) alloys and which can undergo a thermoelastic deformation.
- SME ring-shaped or tubular shaped memory effect
- NiTi nickel
- a compressible component which has been formed as a split ring with a closable gap is positioned between the joint component and two parts to be joined, between which in turn is a sealing ring. Due to the thermoelastic deformation of the connection component, the compressible component is compressed and the gap is closed, whereby the sealed connection of the two parts is achieved.
- the disadvantage here is a material, cost and time-consuming, complex production of the seal or parts thereof and a complicated, time-consuming and costly construction of the device for connecting and sealing the parts.
- the invention is therefore based on the object to reduce or minimize these disadvantages or effects of these disadvantages.
- the seal can be produced as a function of a physical property of a plastic and the physical property of the plastic can be changed as a function of an electrical voltage.
- a plastic referred to hereinafter as electroactive plastic in which at least one of its physical properties is variable as a function of an energy in the form of an electrical voltage. Additionally or alternatively, the energy may be a current flow correlated with the electrical voltage, an electromagnetic field, a heat energy or a light energy.
- seal or seal is here and below referred to a positive connection of at least two components, parts or the like, by means of which an exchange of liquids, gases or particles between at least one, adjacent to a first side of the seal, the first compartment and a second, adjacent to a second side of the seal compartment can be reduced or minimized.
- the seal can be produced once or several times and / or be provided and designed as short-term or permanent. If the term seal refers to an objective seal, then the seal may for example be an exchangeable element or be a component of at least one of the parts themselves.
- the physical property of the electroactive plastic is a shape or volume of the electroactive plastic.
- the shape By changing the shape, the volume or the shape and volume of the seal is possible in a simple and inexpensive way, since a complex vote of sealed parts and / or parts and seal omitted or at least can be simplified.
- the device comprises at least one at least partially formed of electroactive plastic sealing element.
- at least the first and / or second part at least partially be formed of electroactive plastic and be produced by means of this seal.
- the electroactive plastic can be converted by means of the electrical voltage at least from a first shape into a second shape and from the second shape into the first shape.
- the sealing element effects a seal between the first part and the second part.
- the sealing element may be provided as non-sealing.
- the first shape can be assumed upon application of the electrical voltage, in which case the plastic is supplied with energy for producing the seal.
- the plastic when energized, the plastic may take the second form, in which no seal is made and the first shape is without power. As a result, energy consumption is minimized in existing seal, resulting in a cost reduction.
- the sealing element is assigned to the first or second part captive.
- the sealing element can be embodied as a "loose" or exchangeable sealing element, which can be assigned at least temporarily to at least one of the parts, resulting in an improved exchange and renewability of the sealing element as well as a cost reduction, since in one case only one eg Wear-affected sealing element can be replaced.
- the sealing element is particularly preferably a sealing lip assigned to the first part, and the second part comprises a recess corresponding to the sealing lip.
- the sealing lip is also effective for latching the first part to the second part in the event of an engagement in the recess.
- the electroactive plastic is preferably a plastic with a shape memory effect which has at least one first shape (eg an initial shape) with a first volume (eg an initial volume), a second, third, fourth etc. shape with a second, third one , fourth, etc. volumes.
- first shape eg an initial shape
- first volume eg an initial volume
- second, third, fourth etc. shape with a second, third one , fourth, etc. volumes.
- the plastic is its shape, but not its volume, or
- volume but not its shape, changes.
- transitions are possible, for example, from the first shape with the first volume to the third shape while maintaining the first volume.
- a change of shape or volume may be repeated once or several times, e.g. depending on the applied voltage.
- the plastic may gradually or continuously assume at least the starting shape or the starting volume, resulting in flexibility in use and adaptability to different requirements, e.g. Housing forms or locations of the housing results.
- the device for receiving an electrical circuit and / or a device comprising electrical switching means
- said object is achieved according to the invention by at least one first and second part functioning as first and second housing part with such or the apparatus described below.
- the device may be, for example, a housing which encloses electrical components, a control cabinet or the like.
- the seal can relate, for example, to at least one door, a cable feedthrough or a fastening device and at least partially seal it against undesired penetration and / or leakage of, for example, moisture, liquids, gases and / or particles.
- the electrical voltage can be applied by means of a voltage source encompassed by this device or at least temporarily assignable thereto.
- the device includes a lock with a circuit that can be made by inserting a key.
- a circuit can be provided either on the side of the key or on the sides of the castle a voltage source; in both cases, by inserting the key and thereby closing the circuit, the device for producing a seal is subjected to electrical energy, so that the seal is made or dissolved.
- a particularly suitable method for producing a seal between a first part and a second part in particular a first housing part and a second housing part to be specified by means of such or the device described below.
- a first electrical voltage for producing and a second electrical voltage for canceling the seal are applied.
- the first or second applied electrical voltage can be "zero", so it can only be an electrical voltage see either created or canceled the seal.
- FIG. 1 shows schematically a vertical section through a device for producing a seal.
- FIG. 1 schematically shows a vertical section through a device 10 for producing a seal between a first part 12 and a second part 14, in particular a first housing part 12a and a second housing part 14a.
- a sealing element 16 made of electroactive plastic is assigned to the first part 12 captive. If there is no electrical voltage, the sealing element 16 has a first shape 18; upon application of an electrical voltage, the sealing element 16 is transferred into a second mold 20. In this first form 18, the sealing element 16 corresponds to a recess 22 encompassed by the second part 14, whereby a seal is produced between the first part 12 and the second part 14, whereas in the second form 20 the seal is released.
- a latching of the first part 12 with the second part 14 can be generated.
- the invention relates briefly to a device 10 for producing a seal between a first part 12 and a second part 14, in particular a first housing part 12a and a second housing part 14a, the seal depending on a physical Property of an electroactive plastic can be produced and the physical property of the electroactive plastic in response to an electrical voltage is changeable, a device for receiving an electrical circuit and / or an electrical Switching means comprising device, comprising at least one first and second part 12, 14 acting as first and second housing part 12a, 14a with a device 10 of the aforementioned type and a method for producing a seal between a first part 12 and a second part 14, in particular a first housing part 12a and a second housing part 14a, by means of such a device 10, wherein a first electrical voltage for manufacturing and a second electrical voltage is applied to cancel the seal.
