Description

Ready electrical arrangement and subject with such an electrical arrangement

The invention relates to a connection ready electrical arrangement. Furthermore, the invention relates to an article with such a ready electrical arrangement.

Electrical arrangements are known in the art in a variety of ways.

For example, today LED tapes are state of the art in order to illuminate objects in a variety of ways. Such LED strips have in addition to the light-emitting diodes and printed conductors. To protect such tapes they are generally provided with a transparent protective layer.

When connecting these LED tapes to external power sources, contacting is time consuming, difficult, and error prone. It is necessary to remove the protective layer at the desired location, expose the trace accordingly, and then connect the trace to the conductors from the external voltage source, such as by soldering, welding, or otherwise, to facilitate power conduction. Furthermore, the contact point, ie the transition between the LED strip and the connected power line to seal again, for example, to prevent the ingress of moisture to restore adequate media resistance and to avoid a risk of short circuit. Likewise, a cohesive bond is required, since at the Kontaktierstellen, such as solder joints, heat due to electrical losses. Since metals and plastic-based protective layers have different thermal expansion coefficients and plastics generally deform under the action of heat or expand irreversibly without external force, delamination can be expected during operation, which likewise has a negative effect on the resistance of the entire line. Due to the influence of oxidizing media, which can penetrate into the cavity which is thus gradually formed, the electrical resistance is also increased, and the efficiency of the illumination system can thus decrease. This can lead to premature failure of the arrangement. In the case of solder joints, crimp connections and similar joining techniques, irreversible bond breakage or component failure may occur in the case of a tensile load on the component. This is where the invention comes in, the object of which is to provide a ready-to-connect electrical arrangement which enables simplified contact with an external voltage and / or data source.

Furthermore, the ready-to-connect electrical arrangement should have a simple structure, be available in a cost-effective production method and have a high degree of operational reliability, in particular during contacting, such as, for example, polarity reversal protection.

Another object of the present invention is to provide an article with such a ready-to-connect electrical arrangement.

According to the first object is achieved by the features stated in the characterizing part of claim 1.

Further advantageous embodiments of the invention are specified in the subclaims. The solution of the first object of the invention to provide a ready-to-connect electrical arrangement, is carried out according to claim 1. In the present invention, it has been recognized that a ready electrical connection arrangement comprising a support member on the at least one conductor track, at least one electrically operated component and at least a contacting element are arranged, wherein the contacting element serves to produce a flow- and / or data-conducting connection to the at least one conductor track of the ready-to-connect electrical arrangement, then is configured very advantageously, if it is provided that the contacting element has a cavity surrounded by a sheath, in which at least one contact element is arranged, which is connected to the at least one conductor track of the ready-to-connect electrical arrangement, and wherein the envelope has an opening.

Optionally, the ready-to-connect electrical arrangement is surrounded by at least one protective layer. This protective layer also acts in the sense of an insulating material.

The carrier element is in the simplest case a thin film of polymer, cellulose, inorganic paper, metal, ceramic, glass in a thickness of <5 mm, preferably of <500 pm, or a textile carrier. According to the invention, the contacting element thus constitutes a separate component which is arranged on the carrier element of the ready-to-connect electrical arrangement, fastened there and whose contact element present in the cavity surrounded by a sheath is connected to the at least one conductor track of the ready-to-connect electrical arrangement. In this case, the shell has an opening.

The contacting element is designed such that a cavity surrounded by a shell is provided, wherein in the cavity at least one contact element is arranged. This contact element is connected to the at least one conductor track of the electrical arrangement which is ready for connection, so that a current and / or data exchange can take place.

The sheath is designed in at least one location such that an access is formed from the outside to the cavity, which is in the form of an opening in the shell.

Such a contacting element with a cavity enclosed by a shell can be produced in a simple manner from polymer material by bringing it into an approximately parallelepipedal shape, for example an injection molding process and / or a blow molding process and / or a deep drawing process and / or a Laminiervorgang and / or a bonding process and / or a welding operation and / or a combination of the aforementioned can be used.

It has been found in the context of the present invention to be advantageous if it is provided that the cavity is surrounded by the shell. The cavity of the contacting element is thus delimited by the shell, wherein the shell preferably consists of a polymer material. In particular, in the present invention, the cavity of the contacting element has an opening to the outside, and is thus not completely closed. Through the opening, the contacting of the ready-to-connect electrical arrangement can take place.

The choice of the polymer material from which the sheath of the contacting element is formed takes place from the viewpoint of stability, ease of processing, ease of fastening, insulating ability, compatibility and / or weldability with the protective layer with which the electrical assembly ready for connection is optional is surrounded, and the ability to separate the shell at least partially. For example, a thermoplastic and / or an elastomer and / or a thermoset and / or a chemically and / or physically crosslinked polymer material and / or a mixture and / or combination thereof may be used as polymer material, as is the case, for example, in a coextrusion method or a multilayer injection molding method. is borrowed - be used.

Depending on the size of the ready-to-connect electrical arrangement, this cuboid may have an order of magnitude of several mm ^{3 in} volume, up to several cm ³ . The ready-to-connect electrical arrangement of the present invention is designed in such a way that it comprises a plurality of interconnects and / or electrically operated components and / or contacting elements, which are preferably present in a regular arrangement. It may be provided that the electrical arrangement ready for connection has a very long length, that is, for example, is designed as a band which can be wound onto a roll in a simple manner. In another embodiment of the ready-to-connect electrical arrangement according to the invention, this can have a high intrinsic rigidity and be self-supporting. It then has the shape of a rod. In this arrangement, a multiplicity of strip conductors and / or electrically operated components and / or contacting elements can then be present in regular arrangement. In this context, a connection-ready electrical arrangement which has a regularly recurring pattern of conductor tracks, electrically operated components and contacting elements is preferred.

The band-shaped and / or rod-shaped design of the ready-to-connect electrical arrangement also makes it possible to keep the height low and thus easily equip the object to be equipped with the ready-to-connect electrical arrangement and in particular to equip it in a simple manner.

In a further embodiment, the ready-to-connect electrical arrangement of the present invention can be designed in such a manner that it is provided that the contacting element is arranged on one longitudinal side and / or approximately midway between the two longitudinal sides of the band-shaped and / or rod-shaped, ready-to-connect electrical arrangement is. As a result, a particularly simple contacting of the ready-to-connect electrical arrangement becomes possible.

The ready-to-connect electrical arrangement can be produced in a simple manner by designing an electrical arrangement that comprises at least one contact-making element with a cavity surrounded by a shell, in which at least one contact element is arranged, which is connected to the at least one contact element Conductor of the electrical arrangement is connected, and wherein the sheath has no opening.

This electrical arrangement with the contacting element, whose shell has no opening, is subjected to a separation process.

The separation can be carried out such that in addition to the production of the opening in the shell of the contacting element and the same instant the electrical arrangement is severed and thus cut to length. This can easily be accomplished if the contacting element is arranged approximately centrally between the two longitudinal sides of the shaped and / or rod-shaped electrical arrangement. The contact, for example, to an outer Voltage source then takes place according to the opening of the shell centered between these two long sides.

In another embodiment of the invention, in which the contacting element is arranged on a longitudinal side of the band-shaped and / or rod-shaped electrical arrangement, the contacting can be made, for example, to an external voltage source in a simple manner after opening the shell from the longitudinal side. Depending on the need can also be provided that both the contacting element is arranged on a longitudinal side as well as approximately centrally between the two longitudinal sides of the band-shaped and / or rod-shaped electrical arrangement. In both cases, the production of the opening in the shell of the contacting takes place by a separation process.

To facilitate the determination of the location at which the separation process is to be carried out, it is provided that the electrical arrangement has at least one marking element, on which this process is to be carried out. Such a marking element is, for example, a line or a dot arrangement or an arrangement of arrows or the like. The object of the marking element is to define a location or a plane at which the electrical arrangement can be separated by means of a separating process. Such a separation process is, for example, a scissors and / or a knife and / or a laser beam and / or a hot wire cutting process and / or a sawing and / or a milling and / or a planing process and / or a buckling and / or or a breaking process.

The separation of the electrical arrangement on the marking element takes place in a correspondingly defined manner, so that the function of the section of the electrical arrangement produced thereby is not impaired. In particular, there is no danger that electrically operated components or printed conductors will be severed in an undesired manner and lead to malfunctions of the electrical arrangement.

In a further development of the present invention, it is provided that the electrical arrangement ready for connection is designed in such a way that the contacting element has a vertical extent approximately perpendicular to the plane of the carrier element, which approximately corresponds to the height extent of at least one electrically operated component.

In this way, it can be accomplished in a simple manner that the height of the electrical arrangement ready for connection is minimized, which on the one hand is favorable in order to roll up the electrical arrangement ready for connection on a reel, on the other hand the arrangement on an object is possible in a simplified manner, as to this For example, only a groove of shallow depth is to be provided on the object in order to arrange therein the electrical arrangement ready for connection.

In the present invention, the electrically operated component, a luminous element, and / or a sensor element and / or a logic element and / or a contact point and / or a control element and / or a display element and / or a transmitting element and / or a receiving element and / or a camera element and / or a screen element and / or a switching element and / or a touch switching element and / or a measuring element and / or a diagnostic element and / or an acoustic element and / or a loudspeaker element and / or a solar cell and / or a Peltier element and / or a heating element and / or a cooling element and / or an inductive coupling element and / or a resonant coupling element and / or a resonant circuit and / or a switching element and / or a memory element and / or be a combined from the aforementioned element.

In the context of the invention, an electrically operated component is also understood to mean one which generates electricity, such as, for example, a solar cell or a Peltier element.

The data and / or current flow takes place after connection of the ready-to-connect electrical arrangement mono- and / or bidirectional via at least one contacting element to at least one further external connection partner or at least one further external connection partner to the at least one contacting element wherein the at least one further connection partner may be a data source and / or a voltage source and / or a combination thereof.

In the case of a plurality of electrically operated components on the ready-to-connect electrical arrangement, the abovementioned elements can be used in any combination and in any desired number. It is self-evident that these electrically operated components, at least a certain number of them, are in circuit and / or data-conducting connection by conductor tracks. The interconnects are made of copper, glass fiber, polymer optical fiber (POF) or are printed, and have proportionally at least the elements silver and / or platinum and / or copper and / or aluminum and / or gold and / or tin and / or zinc and / or carbon modifications and / or graphene.

In order to arrange the electrically operated components in a simple manner on the carrier element, it may be provided to apply a layer to the carrier element, on which in turn the electrically operated components are arranged. Such a layer may be an adhesive layer or a protective layer or a spacer layer or an insulating layer or a heat-dissipating layer or the like.

The printed conductors are arranged directly on the carrier element, in the layer or on the layer as required.

In a preferred embodiment of the present invention, the ready-to-connect electrical arrangement is designed such that it has a protective layer, wherein the protective layer is preferably formed on all sides on the surface. This protective layer causes the electrical assembly ready for connection to be protected from mechanical forces. Furthermore, this has the advantage that the electrical device ready for connection is protected against corrosive media.

The protective layer may, for example, be applied in the form of a liquid lacquer to the electrical arrangement which is ready for connection. Other techniques include, for example, overmolding in an injection molding process with a polymeric material or coextrusion in an extrusion process with a suitably suitable polymeric material. The protective layer is present as at least one-ply polymeric and / or inorganic film or thin layer, with a thickness of less than 500 μm, and / or as at least one-component extruded and / or coextruded polymer layer and / or as a cast resin layer.
