Definitions
- the invention relates to a housing for electrical line connection between a film conductor and a conductor, and to a method for its production.
- Flexible film conductors sometimes called flat conductors or ribbon conductors, are widely used in vehicle construction, in particular to allow a mobile, electrical contact in limited space conditions.
- Foil conductors usually consist of a tinned copper tape with a thickness of 0.03 mm to 0.1 mm and a width of 2 mm to 16 mm. Copper has been proven for such traces, as it has a good electrical conductivity and a good processability to films and the material costs are low at the same time. Other electrically conductive materials can also be used which can be processed into films. Examples include gold, silver, aluminum or tin.
- the tinned copper tape is applied for electrical insulation and stabilization on a substrate made of plastic or laminated on both sides with this.
- the insulation material is usually made of a 0.025 mm to 0.05 mm thick film based on polyimide. But other plastics or materials with the required insulating properties can be used.
- a foil conductor band may contain a plurality of electrically insulated, conductive layers.
- foil conductors are usually used for contacting electrically functional layers in laminated glass panes. Examples can be found in DE 42 35 063 A1, DE 20 2004 019 286 U1 or DE 93 13 394 U1.
- Such laminated glass panes usually consist of at least two rigid individual glass panes which are adhesively bonded to one another by a thermoplastic adhesive layer.
- the thickness of the adhesive layer is, for example, 0.76 mm.
- Between the individual glass panes are additionally electrically functional layers such as heating coatings and / or antenna elements, which with connected to a foil conductor.
- a suitable foil conductor has only a total thickness of 0.3 mm.
- Such thin film conductors can be embedded without difficulty between the individual glass panes in the thermoplastic adhesive layer.
- film conductors for contacting electrically functional layers is not limited to the vehicle sector. As known from DE199 60 450 C1, film conductors are also used in the construction sector. In composite or insulating glass sheets foil conductors are used for electrical contacting of integrated electrical components such as voltage-controlled electrochromic layers, solar cells, heating wires, alarm loops or the like.
- connection element comprises an approximately 5 cm to 20 cm long foil conductor and at least one round cable with a connector.
- the connection between the foil conductor and the cable is usually done by soldering and is protected by a housing.
- foil conductor Due to the small thicknesses of the metal foil and the insulating films have foil conductor only a low tear protection and even lower tear strength. In particular, when the foil conductor is directed over corners or sharp edges, tensile forces may concentrate on small areas and locally exceed the tear strength of the foil conductor or one of its layers.
- US 5,724,730 and EP 1 058 349 A1 disclose electrical line connectors between foil conductors and round cables by means of soldered connections.
- the housing around the connection point is in each case designed in two parts.
- the inlet opening of the housing for the film conductor has on both sides right-angled, sharp entry edges.
- DE 199 44 493 A1, DE 100 06 1 12 A1 and DE 100 65 354 A1 each describe a connecting element for mechanical fixing and for electrical contacting of foil conductors.
- the inlet opening of the film conductor in the housing is funnel-shaped, each configured with a bevel per leading edge.
- the object of the present invention is to provide a housing for electrical conduction connection of a foil conductor to a conductor, which minimizes damage to the foil conductor at the inlet opening under tensile load.
- the present invention includes a housing having an electrical lead connection between a conductor and a foil conductor.
- the entrance opening the housing for the film conductor is rounded at its inlet edges at least on one side so that the inlet opening is increasingly extended to the outside.
- the rounded region of the leading edge preferably runs parallel to the broad side of the foil conductor. That is, the leading edge is parallel to the broad side of the foil conductor and the edge itself is rounded.
- both the upper leading edge and the lower leading edge of the housing are rounded.
- An embodiment of the housing according to the invention with only a rounded leading edge is advantageous if the housing is connected to a substrate, for example.
- a film conductor then experiences no tensile loading in the direction toward the substrate.
- the rounded leading edge is then advantageously facing away from the substrate leading edge.
- the leading edge facing the substrate, which is arranged between the foil conductor and the substrate, does not have to be rounded since the foil conductor can not be loaded via this leading edge because of the substrate.
- the rounded region of the leading edge preferably extends over an angular segment at an angle of 30 ° to 180 °, preferably 80 ° to 180 °, particularly preferably 135 ° to 180 °.
- the rounded portion of the leading edge preferably begins at the point where the foil conductor emerges from the housing and is no longer firmly connected to the housing.
- a rounding should be understood to mean a round shape without edges and corners, that is to say without places with a very small radius of curvature.
- the rounded region of the leading edge of the housing according to the invention preferably has radii of curvature of at least 0.5 mm. Particularly preferred are the radii of curvature between 0.5 mm and 100 mm, in particular between 0.5 mm and 20 mm.
- the minimum radius of curvature, over which the film conductor is deflected, is decisive for the maximum tensile stress in the film conductor. With a minimum radius of curvature of 0.5 mm, it is ensured that the foil conductor is not damaged during the stresses usually encountered during the production process, during transport, during installation or during use.
- the rounded portion of the leading edge is preferably oval, circular or elliptical.
- a circular rounding corresponds to an angular segment of 180 ° of a semicircular leading edge and an angular segment of 90 ° corresponds to a rounding of the leading edge with the shape of a quarter circle.
- the housing according to the invention is preferably made of an electrically insulating material.
- Thermoplastic plastics and elastomers which are processed by injection molding, are suitable for industrial production. Such injection molding for the production of plastic housings are well known, for example from DE 103 53 807 A1.
- thermoplastics and elastomers for example, polyamide, polyoxymethylene, polybutylene terephthalate or ethylene-propylene-diene rubber is used.
- potting materials such as acrylate or epoxy resin systems may be used.
- the housing can be made of an electrically conductive material with electrically insulating inserts.
- the housing according to the invention is preferably produced as a one-part or multi-part element and then equipped with the electrical line connection, including conductor and foil conductor.
- the housing according to the invention can be cast directly around the electrical line connection between conductor and foil conductor.
- the electrical line connection between conductor and foil conductor is preferably carried out by soldering, bonding or welding. During soldering, soldering with a low-melting solder is preferred. Alternatively, the electrically conductive connection by gluing with an electrically conductive adhesive or terminals, for example by means of a metallic clamp, sleeve or connector done.
- the housing according to the invention is preferably used for electrical line connection of a foil conductor with a conductor, for example a round cable. Both foil conductor and conductor can be constructed multi-core and connected via several points.
- the housing according to the invention can serve for the electric line connection of several foil conductors, preferably each one Ingress opening of the foil conductor in the housing has a rounded portion.
- an electrical line connection between a film conductor and a wire or a metallic contact element for example, to form a plug connection.
- the electrical line connection between a film conductor and a conductor track for example, a circuit board with other electronic components take place.
- the rounded region of the leading edge consists of a separate element.
- the own element may consist of the same material as the housing or another material, preferably a softer material. A soft material can better conform to the foil conductor and distribute an applied force over a larger area. This leads to a reduction in the tensile stress.
- a material for the own element for example, a circular sealing cord or an O-ring of rubber, perfluoro rubber, polyethylene or polytetrafluoroethylene is used.
- the own element is preferably inserted into the housing, clamped or glued to the housing. The own element preferably seals off the interior of the housing, for example against moisture.
- a film conductor experiences high tensile stress peaks. This particularly concerns the edges of the foil conductor, which must absorb a large part of the tension.
- the leading edge in addition to the rounded region, a rounding in the direction of extension of the film conductor on.
- the applied force is distributed over a larger contact area. The occurring maximum tensile stress in the foil conductor is reduced compared to the maximum tensile stress in a housing with a straight edge.
- a new use of a housing has been found in connection with a foil conductor for contacting electrically functional layers on or in single-pane safety glass panes or multi-pane laminated glass panes.
- electrically functional layers are, for example, heating conductors and / or antenna conductors.
- the use of the housing according to the invention is carried out in conjunction with foil conductor connections in the vehicle sector or in the construction sector.
- the invention also encompasses a composite pane with a foil conductor for contacting electrically functional layers in its interior.
- the film conductor is thereby electrically connected in a housing according to the invention with another conductor.
- the object of the invention is further achieved by a method for producing a housing with an electrical line connection between a conductor and a foil conductor.
- a first step (a) the conductive layers of foil conductor and conductor are electrically conductively connected to one another.
- the electrically conductive connection is preferably carried out by soldering, bonding, welding or gluing with an electrically conductive adhesive.
- the electrically conductive connection can be made by a continuous pressing or clamping, for example by means of a metallic clamp or sleeve.
- a second step (b) the connection between the film conductor and the conductor is inserted into a first housing part.
- a second housing part is fittingly placed on the first housing part and connected to it.
- At least one of the housing parts preferably both housing parts, have a rounded area at the entry edges for the foil conductor.
- the connection of both housing parts takes place by gluing, fusing, screwing or jamming, for example by latching mechanisms.
- Both entry edges can already be made with a correspondingly rounded shape during their production.
- the rounding off can take place in a separate step, for example by means of milling, grinding, other ablative methods or smelting.
- the housing becomes direct around the connection between the foil conductor and the conductor molded, for example by injection molding.

- Figure 7 shows an enlarged section of the inlet opening (8) of a longitudinal section along the line II of Figure 1 by an inventive housing (7, T).
- the curvature of the entry edges (9, 9 ') can not be described by a single circle segment with a constant radius.
- the curvature circle with radius n describes the curvature at the point (14) of the rounded leading edge (9 ').
- Point (14) is at the point of greatest curvature, and thus at the point with the smallest radius of curvature of the entire rounded region.
- a second circle of curvature is applied by way of example at point (1 5) of the rounded leading edge (9 ') and has a radius of curvature of r 2 .
- FIG. 8 shows a longitudinal section through an inventive housing (7, T) with attached circular elements (12, 1 2 ') in the region of the entry edges (9, 9').
- the elements (12, 1 2 ') are connected by gluing to the housing (7, 7').
- Circular sealing cords or O-rings of rubber, perfluororubber, polyethylene or polytetrafluoroethylene can be used for the elements (1 2, 1 2 ') in a non-limiting manner.
- Figure 9 shows a longitudinal section through an inventive housing (7, 7) with in the housing (7, 7 ') inserted circular elements (12, 1 2').
- the elements (1 2, 12 ') are here in a recess in the region of the entry edges (9, 9') fitted.
- FIG. 10 shows a longitudinal section through a further embodiment of a housing (7) according to the invention.
- the housing (7) according to the invention is designed as a half-shell and connected to a substrate (16), for example with a glass pane.
- the connection between housing (7) and substrate (16) can be done for example by gluing or clamping.
- the conductor (4) may be, for example, a round cable.
- the electrically conductive region (5) of the conductor (4) may be a metallic contact surface or a foil conductor, which is preferably connected to the substrate (1 6).
- the rounding according to the invention at the leading edge (9) of the film conductor (1) into the housing (7) reduces the maximum tensile stress in the film conductor (1) at a tensile load in the direction away from the substrate (16).
- Edge element own element for rounding the leading edge
