Definitions
- the invention relates to a housing for an electrical device according to claim 1, an electrical device with such a housing, a method for producing a housing for an electrical device and a method for producing such an electrical device.
- Housings for electrical devices have become particularly important in the electrical engineering industry, where they hold, for example and in particular, electronic components, assembled circuit boards and/or cables, such as electrical cables, photonic conductors and also conductor tracks used on a circuit carrier, in or in different positions. These should typically meet the high requirements for intended use that are usual in the industrial sector. They are, for example and in particular, set up and designed to protect the electronic components, assembled circuit boards and/or cables arranged on or in the housing, which serves as the base body, from the effects of external environmental influences. Furthermore, they should regularly ensure functional reliability over a long service life that is usual for equipment in the industrial sector and also trouble-free operation of a system with the housing. At the same time, they should not pose any health hazards.
- a printer housing is made from a biodegradable material, namely water-soluble cellulose.
- the disadvantage here is that a coating of wax paper is necessary to protect against water, which makes production complex, and due to the mechanical properties of the material, only a relatively small proportion of the printer housing can be manufactured in this way.
- Housings for electrical devices are usually made of a polymer or metal.
- Polymers have established themselves very early on in the industrial sector as cost-effective and easily moldable materials for different areas and tasks and cover a very wide range of applications.
- the problem with plastic materials is that they can represent a high environmental impact.
- the object of the present invention is to improve the environmental balance of a housing for an electrical device or its production. This object is solved by an article having the features of claim 1.
- a housing is provided, in particular for an electrical device, which is at least partially made of a material comprising a plastic which is a polymeric secondary raw material and/or is a bio-based polymer (e.g. made from regeneratively and/or biologically produced synthesis gas and/or liquids and/or general reactants) and/or is a biodegradable polymer.
- a material comprising a plastic which is a polymeric secondary raw material and/or is a bio-based polymer (e.g. made from regeneratively and/or biologically produced synthesis gas and/or liquids and/or general reactants) and/or is a biodegradable polymer.
- the invention solves the problem set by a material approach to reducing the environmental impact. To solve the problem, the invention moves away from an approach of reducing the use of a polymer obtained from a fossil raw material simply by changing the geometry of the housing in order to only use the fossil raw materials to a reduced extent. Furthermore, the invention moves away from the approach of replacing a plastic material with another material such as a metal.
- the selection is therefore not limited to a specific one of the aforementioned plastics, so that they can also be combined with one another.
- the material can consist of at least one of the aforementioned plastics, but can also contain other material additives, such as additives or other polymers or polymer components. Furthermore, composite materials can also be used for the material. It is also possible to mix the aforementioned plastics with other components, for example additives or primary polymers.
- the housing described here makes it possible not only to noticeably reduce the environmental impact, but also to significantly reduce the impact on raw material resources. Furthermore, the housing can meet the sometimes high requirements for its usability, e.g. in terms of electrical breakdown safety, fire protection and/or electrical insulation, which are usually implemented using primary materials.
- the material comprises several different plastics. Each of the several different plastics can be a polymeric secondary raw material and/or made from renewably and/or biologically produced synthesis gas/liquids/educts and/or be biodegradable.
- the material comprises a polymeric secondary raw material and a renewable raw material.
- the material comprises a polymeric secondary raw material and a biodegradable raw material.
- the material comprises a renewable raw material and a biodegradable raw material.
- the material comprises a polymeric secondary raw material and a renewable raw material and a biodegradable raw material.
- one and the same plastic of the material is both a polymeric secondary raw material and a renewable raw material.
- one and the same plastic is both a polymeric secondary raw material and a biodegradable raw material.
- one and the same plastic is both a renewable raw material and a biodegradable raw material.
- one and the same plastic is both a polymeric secondary raw material and a biodegradable raw material.
- one and the same plastic is both a renewable raw material and a biodegradable raw material. In this way, particularly environmentally friendly housing can be provided.
- the housing can therefore be made from several different materials, each of which can comprise a plastic that is a polymer secondary raw material, is made from renewably and/or biologically produced synthesis gas/liquids/educts and/or is biodegradable.
- a housing that is environmentally friendly and at the same time particularly well adapted to application-specific requirements.
- the housing has a first housing part or a first housing section made from a first such material and a second housing part or a second housing section made from a first such material.
- the housing sections can be connected to one another in a form-fitting or material-fitting manner.
- the polymeric secondary raw material can be a conventional and/or chemically recycled thermoplastic.
- Conventionally recycled thermoplastics are, for example, mechanically recycled and/or produced by melting.
- Conventionally recycled thermoplastics differ from corresponding primary, i.e. non-recycled thermoplastics typically in that they have correspondingly shorter polymer chains.
- Conventionally recycled materials differ from standard materials regularly in their additional thermal stress, as the polymers are typically melted at least once more than the original standard material. If additional granulation processes are planned before the second processing/use, the additional thermal stress/damage can be increased.
- For chemically Certificates for reduced CO2 content are typically issued for recycled materials. This usually allows a corresponding CO2 reduction to be claimed retrospectively.
- the material consists of at least 25% by weight of the plastic, which is a conventionally and/or chemically recycled thermoplastic, in particular at least 50% by weight or even 100% by weight. This enables a substantial improvement in the environmental balance, the so-called CCh footprint of the material.
- the polymeric secondary raw material is a conventionally recycled thermoplastic, which can be an engineering thermoplastic.
- the polymeric secondary raw material is a conventionally recycled thermoplastic and/or selected from the group of polycarbonate, polyamide, polyethylene, polyethylene terephthalate, polyvinyl chloride and polypropylene. These materials enable particularly good properties for many areas of application.
- the material consists of 10 to 100 wt.% (or 10 to 80 wt.%) of the plastic made from renewably and/or biologically produced synthesis gas/liquids/educts. This makes it possible to provide a particularly resource-saving housing.
- the plastic of the material is made from regeneratively and/or biologically produced synthesis gas/liquids/educts, whereby the renewable raw material is selected from sugar, starch, protein, cellulose, lignin, fat and/or vegetable oil, in particular castor oil.
- the plastic of the material can be made from regeneratively and/or biologically produced synthesis gas/liquids/educts and can be in the form of polylactide, polyhydroxyalkanoate, cellulose derivative, in particular cellulose ester or cellulose butyrate, polyethylene, starch derivative, polyamide 4.6 or polycarbonate. This also enables an environmentally friendly and at the same time robust housing.
- the plastic of the material is biodegradable and can be in the form of polybutylene adipate terephthalate, polyhydroxyalkanoate, polylactide, starch blend or polyester.
- the housing can be easily composted after use, optionally also with the notification of additives for composting. This makes disposal particularly environmentally friendly.
- the housing can also have a fastening point for a component.
- the fastening point is (firmly) connected to the rest of the housing via a predetermined breaking point. This allows the component to be easily broken out before recycling, so that the housing material can be recycled optimally.

- the electrical device has an input magazine and an output magazine for the rigid print media.
- the media holder and/or the printing unit are designed such that plastic- or metal-based rigid printing media in the form of plates, strips or signs can be printed.
- One or more movable parts can be arranged in or on the housing of the device.
- the movable part or parts are also at least partially made from a material that includes a plastic that is a polymeric secondary raw material, is made from renewably and/or biologically produced synthesis gas/liquids and/or is biodegradable.
- the movable part or parts can be made from the same material as the housing. This enables an even further improved environmental balance and also simplified production.
- At least one component arranged in or on the housing is attached to the housing via a predetermined breaking point in the housing. This allows the component to be easily broken out and separated quickly and easily into different types when recycling the device.
- a method for producing a housing in particular for an electrical device, is specified.
- the method comprises providing a material that comprises a plastic, wherein the plastic is (or will be) produced by recycling a thermoplastic, is (or will be) produced from regeneratively and/or biologically produced synthesis gas/liquids/educts and/or is (or will be) biodegradable, and forming the housing at least partially, optionally completely, from the material.
- the advantages reference is made to the above information on the housing.
- the method can be used to produce the housing according to any embodiment described herein.
- a selection can be made from a variety of polymers, in particular polycarbonate, acrylonitrile-butadiene-styrene, polymethyl methacrylate, polystyrene, polyetherimide, polyethersulfone, polysulfone, polyphenylene oxide, styrene-acrylonitrile, polystyrene, polymethyl methacrylate, polypropylene, polyethylene, thermoplastic polyurethane, polyacetal, polyethylene terephthalate, polybutylene terephthalate, polyarylates, polysulfones, polyphenylene sulfide, polyether ketone, polyimides, polyetherimide, polyphthalamide, polyoxymethylene, polyetheretherketone and/or polyamide, e.g. PA 66.

- An alternative or additional conventional recycling can include shredding.
- Chemical recycling includes, for example, solvolysis, depolymerization, pyrolysis and/or gasification. This makes it possible to produce particularly high-quality recycled thermoplastics.
- a method for producing a (particularly electronic) device comprises producing a housing according to the method described above in any desired configuration and arranging one or more (e.g. electrical and/or electronic) components in the housing.

- the polymeric secondary raw material is, for example, a conventionally (for example mechanically and/or by melting) and/or chemically recycled thermoplastic.
- the material consists, for example, of at least 25% by weight of the polymeric secondary raw material.
- the polymeric secondary raw material can be an engineering thermoplastic, in particular polycarbonate, polyamide, polyethylene, polyethylene terephthalate, polyvinyl chloride or polypropylene.
- Thermoplastics have the advantageous property of good formability and processability, as they can, for example, soften to the point of flowing through the application of heat and are thus easy to form. After a cooling phase, they become solid again and retain their shape.
- Industrial plastic waste is often available in large quantities and is often sorted by type, which means that sorting or cleaning work can be kept to a minimum and the waste is then immediately available for recycling. For example, it is shredded and can then be reused to form the 1 A housing.
- the material can consist of 10 to 100% by weight of the plastic produced from renewably and/or biologically produced synthesis gas/liquids/educts.
- the renewable raw material can be sugar, starch, protein, cellulose, lignin, fat and/or vegetable oil.
- the renewable raw material can be castor oil.
- Bio-based polymers can also be referred to as technical biopolymers and can be made from biogenic raw materials, preferably renewable plant raw materials. Organic waste can also be used for this purpose, which can further increase or increase sustainability.
- Renewable raw materials include, for example and in particular, rapeseed and corn, which are available or can be grown in large quantities.
- a bio-based polymer that is also biodegradable is particularly environmentally friendly.
- bio-based polymers are polybutyrate adipate terephthalate (PBAT), so-called starch-based biodegradable blends or polylactide (PLA), polyhydroxyalkanoates (PHA), cellulose derivatives, e.g. cellulose esters (CA) and cellulose butyrate (CAB), so-called biodegradable polyesters as well as starch derivatives.

- bio-polyethylene can correspond to the properties of a conventional polyethylene based on a fossil raw material (primary polymer).
- the plastic of the material can be biodegradable and be in the form of, for example, polybutylene adipate terephthalate, polyhydroxyalkanoate, polylactide, starch blend or polyester.
- a biodegradable portion of the material can be detected by carbon detection.
- a material is biodegradable in particular if the degradation in question occurs through a chemical process in which microorganisms present in the environment convert the material into natural substances such as water, carbon dioxide and compost (in particular, artificial additives are not required). The process of biodegradation depends on the environmental conditions (e.g. location or temperature), the material and the applications.
- Biodegradable polymers include PBAT, PLA and PHA.
- the biodegradable plastics can be enriched with additional properties using additives based on fossil or renewable raw materials, so that, compared to conventional polymers, additional, possibly specific material properties can be created with regard to the desired labeling and/or printing properties, light resistance, water vapor permeability or even biodegradability. These polymers therefore open up a wide range of uses through specific adaptation of the material.

- a power supply unit e.g. the printer according to Fig. 3.
- Several electrical components are accommodated in the housing 1 E, such as a transformer or the like. Further electrical components in the form of a cable 5 connected to the housing 1 E, a power switch and a socket for a connector are illustrated in Fig. 6.
- the housing 1 E has a first housing part 17 in the form of an upper shell and a second housing part 18 in the form of a lower shell, which together define an interior space. Both housing parts 17, 18 are made of the material described here and using the method described here, each of any design. Both housing parts 17, 18 of the example shown are made of the same material.
- FIG. 7 an arrangement of disc-shaped housings 1 F is shown as representative of a large number of other examples of housings, each of which serves as a line carrier.
- the housings 1 F are arranged or can be arranged in a row on a support rail 4.
- the individual housings 1 F are each designed and constructed as industrial electronics housings for housing electrical and electronic components, such as connections 15 (representatively marked once in Fig. 7), circuit carriers, such as circuit boards, electrical and electronic components, among other things as components of a populated circuit board.
- the connections 15 are used to connect cables for electrical power, data and/or signal transmission and are designed and constructed accordingly for this purpose.
- Each housing 1 F has a locking foot 16, by means of which the respective housing 1 F can be snapped onto the mounting rail 4.
- the housings 1 F have electrical connections which are connected via lines inside the housing 1 F either directly to one another or to the aforementioned components, in particular a circuit board.
- the housings 1A-1 F described here can keep the quality of implementation at the same level as conventional production despite reduced CO2 emissions.
- polymers made from a secondary raw material can be used that are an equivalent substitute for a polymer made from a fossil raw material.
- the housings 1A-1 F described here have the advantage that recycled polymers can be used for high-quality products or components or assemblies as well as sections thereof and their use is not limited to packaging purposes or areas of use with low requirements.
- the housings 1A-1 F described here make it possible to noticeably reduce the CO2 pollution of the environment by opening up a broad range of applications for secondary polymers.
- At least the compostable/biodegradable polymer meets at least the requirements of DIN CERTCO DIN EN 13432 in the version valid in 2021.
