Description

The present invention relates to a coding frame for mounting on an electronics housing, a kit that includes a coding frame and a matching electronics housing, and an electrical device with such a kit.

Electrical or electronic devices, in particular household appliances, usually include at least one control unit with at least one circuit board, which is connected to electrical and/or electronic components of the respective device via one or more cable harnesses.

The cable harnesses generally include a coding frame with one or more plug receptacles into which the intended edge card plugs are inserted. When producing the respective device, the coding frames of the cable harnesses prefabricated in this way can then be inserted into a recess in the electronics housing. Inside the recess, suitable contacts are arranged in such a way that the individual edge card connectors inserted into the coding frame are connected to the (respective) circuit board. In this way, the multiple edge card connectors can be positioned simultaneously in such a way that the intended control of the device is guaranteed.

Depending on the device and a position on the electronics housing in which the coding frame is to be used, it may be advantageous to provide protection for the edge card connectors used. Similar solutions are particularly available in the DE 102016207109 A1 or the DE 202010014287 U1 disclosed.

The present invention is based on the object of providing a technology with which edge card connectors can be secured in a coding frame and protected against external influences.

The task is solved by a coding frame according to claim 1, a kit according to claim 6 and an electrical device according to claim 9. Advantageous

Embodiments are disclosed in the subclaims, the description and the figures.

A coding frame according to the invention is intended to be mounted on a (suitable) electronics housing. It has a receptacle cassette into which at least one edge card connector can be inserted, as well as a hinged closure that is pivotally connected to the receptacle cassette. The coding frame can either assume a closed state in which the hinged closure covers the recording cassette (i.e. closes in one direction), or an open state in which the hinged closure releases the recording cassette (e.g. for inserting the edge card connector(s).

A coding frame according to the invention thus makes it possible, in particular, to prevent inserted edge card plugs from being unintentionally removed from the receiving cassette in its closed state and to shield the edge card plugs towards the side of the folding closure. Due to the connection of the hinged closure and the receiving cassette, the coding frame is particularly advantageous for the modular production of an electrical device because it can be delivered as a coherent component, stored and inserted into an electronics housing, which means a simplification of logistics and the insertion process.

In the closed state of a coding frame according to the invention, the receiving cassette is preferably completely covered or closed by the folding closure in the direction of the folding closure. In particular, the hinged closure, when it covers the recording cassette, preferably seals it against moisture penetrating the coding frame from its direction. If aligned accordingly, the coding frame can act particularly advantageously as a drip-water protection.

A kit according to the invention comprises an electronics housing for an electrical device and a coding frame according to the invention according to one of the embodiments disclosed in this document. The electronics housing has a recess (i.e. a connection recess) into which the coding frame is inserted or is to be inserted. Inside the recess, suitable contacts are arranged so that edge card connectors, when inserted into the coding frame or its receiving cassette, are connected to a (respective) circuit board. By inserting the coding frame into the recess, the several edge card connectors can be positioned simultaneously in such a way that the intended control of the device is guaranteed. In this sense, the electronics housing and coding frame of a kit according to the invention fit together.

Based on an intended arrangement of the electronics housing in the intended electrical device, the recess is preferably arranged on an upper side of the electronics housing; The folding closure is then preferably set up to be inserted and When the coding frame is closed, cover the recording cassette from above. In such embodiments, the folding closure serves to protect against dirt and/or dripping water falling in from above.

An electrical device according to the invention comprises a kit according to the invention installed or installable therein according to one of the embodiments disclosed in this document.

The electrical appliance according to the invention or an electrical appliance for which a coding frame according to the invention is provided can in particular be a household appliance, for example a large household appliance (such as in particular a refrigerator, a dishwasher or a washing machine) or a small household appliance (e.g. a vacuum cleaner, a coffee machine or a food processor ).

The receiving cassette of a coding frame according to the invention can in particular comprise a plurality of (at least two) receiving slots for edge card plugs, into which preferably one edge card plug is to be inserted in a form-fitting manner. An opening of such a receiving shaft, through which an edge card connector is to be inserted, is preferably closed by the folding closure when the coding frame is closed.

The plurality of receiving shafts can in particular comprise at least two differently designed receiving shafts. These can be set up to accommodate different edge card connectors, which can differ, for example, in their type (e.g. their number of poles or at least a distance between their poles), their size or at least one of their dimensions and / or their geometric shape.

The connection between the hinged closure and the receiving cassette can include at least one joint; Such a joint preferably then has exactly one degree of freedom. It can in particular be a swivel joint.

According to advantageous embodiments, the connection between the folding closure and the receiving cassette of a coding frame according to the invention comprises at least one film hinge. Such a coding frame is particularly easy to produce (particularly by machine).

Preferably, such a film hinge extends continuously along an edge of the folding closure facing the receiving cassette; In particular, it can take up at least 80% or even at least 90% of the edge. Based on the recording cassette, a length of the film hinge in the direction of its folding axis (i.e. the hinge axis) can (alternatively or additionally) preferably be at least 90% or even at least 100% of an extension of all the recording shafts encompassed by the recording cassette together in this direction (or parallel to it). be. In this way, the film hinge forms an effective barrier that prevents dirt and/or moisture from penetrating between the recording cassette and the folding closure or into the receiving shafts on the hinge side.

A coding frame according to the invention can in particular be made entirely or partially from plastic, for example by injection molding. According to preferred embodiments, a coding frame according to the invention is designed to be monolithic.

According to advantageous embodiments, the receiving cassette of a coding frame according to the invention comprises at least one fastening element which is designed to latch with a suitable holding element on the electronics housing when the coding frame is inserted.

The electronics housing of a kit according to the invention, which includes such a coding frame, preferably has at least one such matching mounting element, which is therefore designed to latch with the at least one fastening element of the coding frame in the inserted state.

In such embodiments, at least one access to the fastening element of the coding frame in its inserted state can be formed in the electronics housing, i.e. an opening that leads from an external environment of the electronics housing to the fastening element: Such access enables the fastening element to be released from its locked state using a tool ( e.g. a screwdriver) that can be inserted through the access.

The fastening element or the holding element can in particular comprise an elastically flexible (deformable) element, the spring force of which, when inserted, presses against the other element (i.e. holding element or fastening element) and thus counteracts the coding frame being released from the recess.

According to advantageous embodiment variants, the folding closure comprises one according to the invention The coding frame has at least one edge region which is designed to protrude beyond a boundary of a recess in the electronics housing when the coding frame is closed when the coding frame is inserted into the recess. When the coding frame is closed, the edge region of the folding closure can, in particular, prevent moisture from penetrating into an intermediate space between the coding frame and the electronics housing. Preferably, the at least one edge region is orthogonal to a folding axis about which the folding closure can be pivoted relative to the receiving cassette.

Embodiments are advantageous in which a coding frame according to the invention has at least one locking device for releasably locking the receiving cassette and the folding closure with one another in the closed state of the coding frame. Such a latching device can in particular comprise at least a first latching element on the receiving cassette and at least a second latching element on the folding closure, the first and second latching elements being designed to be releasably latched to one another in a closed state of the coding frame. Such embodiments enable an advantageous securing of the closed state of the coding frame used.

One of the two locking elements can be formed from an elastically flexible material and can be designed to snap into a structure formed by the other locking element; A spring force of the elastically flexible material then preferably counteracts loosening of the locking connection. The other locking element can also be at least partially elastic or dimensionally stable.

One or more guide elements can be arranged on the folding closure, which in the closed state rest on the receiving cassette or on one or more stabilizing elements possibly arranged thereon.

In this way, the coding frame can be stabilized in its closed state, and in embodiments with at least one latching device and/or at least one closing element (as described above or further below), the respective latching or interlocking process can be supported by the fact that the guide element or (if necessary) at least one of the guide elements is preferably designed to slide along a respective stabilizing element when the coding frame transitions into its closed state.

At least one closing element can be arranged on the hinged closure of a coding frame according to the invention, which is designed to hook onto a (suitable) profile on the electronics housing when the coding frame is inserted and closed. The electronics housing of a kit according to the invention with such a coding frame preferably has such a profile, which is then set up to hook onto its at least one closing element when the coding frame is inserted and closed.

When inserted and closed, such a closing element preferably rests at least partially on an outer surface of the electronics housing, so that it is arranged in an accessible manner and is therefore easy for a user to use to open the coding frame.

Particularly preferred are embodiment variants in which the closing element comprises a snap handle, which is designed to be elastically flexible in at least one section (for example pivotable relative to the folding closure against a spring force) and is designed to lock with the profile in the stated state, for example at least partially around that to reach around the profile.

The hinged closure of a coding frame according to the invention can comprise a protruding area which projects over the receiving cassette when the coding frame is closed; a dimension perpendicular to a folding axis, about which the folding closure can be pivoted relative to the receiving cassette, is then larger for the folding closure than for the receiving cassette.

This simplifies the operation of the folding closure. Particularly in embodiments that include the above-mentioned latching elements, a leverage effect can be created with the protruding area and the release of the latching connection can thus be made easier.

In the above-mentioned variants with at least one closing element, this can be arranged on the protruding area. This enables an advantageous position of said profile on the electronics housing, even away from contacts with which edge card plugs inserted or to be inserted into the coding frame are to be connected. In particular, finger protection can be guaranteed in this way.

Preferred exemplary embodiments of the invention are explained in more detail below with reference to drawings. It goes without saying that individual Elements and components may also be combined differently than shown. Reference symbols for corresponding elements are used across the figures.

• 2c : the kit of the 2a , 2 B in the cutout after mounting the coding frame on the electronics housing.

In the 1a and 1b An exemplary embodiment of a coding frame 1 according to the invention is shown in a different perspective view. The 2a - 2c show an exemplary kit according to the invention, which is in the 1a , 1b illustrated coding frame 1 and an electronics housing 100. Due to the correspondence of the coding frames shown, some of the figures are described simultaneously below to avoid repetition. It is understood that, although only one exemplary embodiment of a coding frame according to the invention is shown in the figures, alternative variants (in particular as described above) are also within the scope of the present invention.

The monolithically designed coding frame 1 comprises a receiving cassette 10, which in the present case has four receiving slots 11a, 11b, 11c, 11d for one edge card connector each. The receiving slot 11a of the receiving cassette 10 is here set up to accommodate an edge card connector of a different type (in particular a different size) than the receiving slots 11b, 11c, 11d. In the 2a associated edge card connectors 200a, 200b, 200c, 200d are shown before they are inserted (in the direction of the arrow) into the receiving slots of the coding frame 1 2 B and 2c each show the coding frame with edge card connectors inserted.

Furthermore, the coding frame 1 includes a hinged shutter 20 and a film hinge 30, which connects the recording cassette 10 and the hinged shutter 20 to one another.

The 1a shows the coding frame 1 in the open state, in which the folding closure 20 releases the recording cassette 10 and thus edge card plugs can be inserted into the receiving slots. By pivoting the folding closure 20 in the direction of the arrow (around the folding, i.e. hinge, axis of the film hinge 30), the coding frame 1 can be transferred to its closed state, in which the recording cassette 10 is completely covered by it in the direction of the folding closure 20; this state is in the 1b from below, i.e. shown in a perspective that shows the recording cassette from one to show the 1a facing opposite direction.

The coding frame 1 includes two locking devices for releasably locking the folding closure 20 on the receiving cassette 10 when the coding frame is closed. In this example, the latching devices each include first latching elements 13a, 13b on the receiving cassette 10 and second latching elements 23a, 23b on the folding closure; In this case, the second latching elements 23a, 23b are designed to be elastically flexible and are each designed to grip around the hook-like first latching elements 13a, 13b when the coding frame is closed.

The latching process when closing the folding closure is supported in the exemplary embodiment shown by the fact that guide elements 24a, 24b, 24c, 24d arranged on the folding closure 20 slide along an associated stabilizing element 14a, 14b, 14c, 14d arranged on the receiving cassette when latching.

The coding frame 1 is intended or set up to be inserted into a recess 110 of an electronics housing 100 during its assembly; this is in the 2a shown.

Fastening elements 12a, 12b on the receiving cassette 10 are designed to latch with a respective holding element on the electronics housing 100 and thus fix the coding frame in the recess; in the 2 B Due to the perspective, only the fastening element 12b and the associated holding element 112b are visible.

An access Z on the electronics housing to the fastening element 12b, which is presently designed in the form of a gap, enables a user to act on the fastening element 12b after inserting the coding frame into the recess 110 to release the latching using a tool, for example a screwdriver; The same applies to the opposite fastening element 12a (see 1b) .

The recess 110 is preferably formed on a top side of the electronics housing 100 (within an electrical device in its intended orientation). The coding frame 1 is then particularly in the 1a , 2a , 2 B , 2c To use the orientation shown, so that the folding closure 20, when folded in the direction of the arrow, covers or closes the receiving shafts 11a, 11b, 11c, 11d upwards. When in use, the hinged closure 20 protects edge card connectors 200a, 200b, 200c, 200d inserted into the receiving slots, as well as the contacts connected to them, in particular from the ingress of dripping water.

Like in the 1a is visible, the film hinge 30 extends continuously along an edge of the folding closure facing the receiving cassette and takes up approximately 90% of the edge. An extension of the receiving shafts 11a, 11b, 11c, 11d taken together in the direction of the folding axis (essentially) corresponds to the length of the film hinge measured in this direction. The recording cassette and the folding closure are thus connected to one another to a corresponding extent on the sides facing each other. The film hinge 30 thus forms a reliable barrier and protects on its side the receiving slots or any edge card plugs inserted therein from the (horizontal) penetration of dirt and/or moisture between the receiving cassette 10 and the hinged closure 20.

In the present case, two closing elements 21a, 21b are arranged on the folding closure 20 of the coding frame 1. These are designed to work when the coding frame is inserted, as shown in 2c is shown to hook with a profile on the electronics housing 100 when the folding closure is folded onto the receiving cassette and the coding frame is therefore in the closed state. In the exemplary embodiment shown, the profile is given by two projections 121a, 121b, which are encompassed by the closing elements 21a, 21b, which are preferably each elastic and designed as a snap handle, when the coding frame is closed (not shown).

The projections 121a, 121b are in the (in the 2a - 2c shown) intended use orientation of the electronics housing is arranged on a vertical outer surface of the electronics housing; This ensures finger protection in particular. When the coding frame is closed, the closing elements 21a, 21b rest on the outer surface mentioned (not shown). This means that when the coding frame is closed, no dripping water can penetrate into the receiving shafts in this area.

The distance between the inserted receiving cassette 10 and the projections 121a, 121b is bridged in the closed state of the coding frame by a projection area 25 of the folding closure 20, which projects over the receiving cassette 10 when the coding frame is closed and on which the closing elements 21a, 21b are respectively arranged . The projection area 25 also provides a lever which makes it easier to release the locking devices made up of first locking elements 13a, 13b and second locking elements 23a, 23b when opening the coding frame.

The folding closure 20 also has two edge areas, one of which in the 1a , 1b Due to the perspective, only the edge area 22b is visible and which limit the folding closure perpendicular to the film hinge 30. In the present case, the edge regions are each designed as a channel which is designed to define a respective boundary 122a, 122b (see 2a) to protrude beyond the recess 110 in the electronics housing and to partially grasp it or accommodate it inside the channel when the coding frame is inserted into the recess and is in the closed state. As a result, a particularly good seal is achieved by the folding closure 20.

Disclosed is a coding frame 1 for mounting on an electronics housing 100. The coding frame comprises a receiving cassette 10 for at least one edge card connector 200a, 200b, 200c, 200d and a folding closure 20. This is pivotally connected to the receiving cassette 10 and is set up to do so, optionally in a closed manner State of the coding frame to cover the recording cassette or to release the recording cassette in an open state of the coding frame.

Also disclosed are a kit 100 with an electronics housing 100 and a coding frame 1 as well as an electrical device that includes a kit installed or capable of being installed therein.
