Abstract

The problem addressed by the invention is that of providing an electrical component carrier which makes it possible to detect the position of the microswitch. In order to solve the problem, an electrical component carrier (1) is provided having a base part (2) made of electrically insulating material and electric conductor paths (2, 3, 4, 5, 17) for connecting electrical components, the conductor tracks being encased by the material of the base part. At least three electric conductor paths (4, 5, 17) of the electrical component carrier (1) are an integral part of an electric microswitch. The microswitch comprises an arc-shaped conductor element which is elastically deformable. When the microswitch is actuated, the arc-shaped conductor element (6) is elastically deformed in such a way that the two end regions (7) of the conductor element (6) are displaced. As a result of the displacement, two electric conductor paths are electrically connected to one another or else an electrical connection between two conductor paths is broken. The displacement therefore brings about electric switching. As a result of the invention, an electric switch need not be soldered to projecting contacts of an electrical component carrier. Conductor paths, which are already present on an electrical component carrier, are an integral part of the electric switch. Production is therefore simplified. Since at least three electric conductor paths are part of the switch, the position of the switch can be detected easily. The switch is constructed in a very simple and hence robust and durable manner.

The invention b for an electric motor kornponententröger particular for a .Kraftfahrzeug embedded in an electrically insulating material interconnects., Electrical connections and an integrated icroschalfer.

A Eiektrokdrnponententräger is a self-supporting component with a housing and inserted into the housing electrical conductor tracks, d e have been punched out of a sheet in principle. The inserted tracks are scratched with insulating material um.sp and so. Protected against environmental influences. The Materrai. The conductor tracks are so thick and thus stable that conductor tracks can serve as onfakfsfiffe. In addition, the material is basically flexible, so that conductor ends can be bent in order to make contact in a desired direction. Basically, the interconnects are made of metal and are in particular 0, 1 mm to 1 mm thick.

Electrical components are connected to the electrical terminals such Leite.Tbahneinhe ^'tt, such as switches, detectors, electronic components or electric motors, such electrical components can be found for example in a Sehjoss, particularly Türsc.hioss a motor vehicle,

A microschaifer is an electrical switch with low separation of the contacts in the open state. The distance is only a few millimeters and allows only small electrical loads that can be switched. Low electrical loads in this sense are found in motor vehicle locks. ,

For the production of an electrical component carrier, conductor tracks are usually first punched out of a metal sheet and, if necessary, additionally prepared by bending, for example, for the provision of contact lugs and / or drilling. The prepared tracks _. , which may still have supporting and / or connecting webs, then a housing of the Elektrokomponentenfrögers be inserted i. Subsequently, insulating material is injected into a first step in order to fix the conductor tracks in the housing. Then connecting and / or supporting webs · - if present - are separated between the interconnects. Finally, the housing is filled by injecting insulating material in the intended manner,

Contact lugs protrude from the insulating material to contact components such. to be connected to a switch, for example by soldering. The above con tact flags form the electrical connections of Eiektrokomponen support. For example, according to the German patent application 1 0201 22 1 1 756 a switch is used at the designated place, so that its confections can be soldered to the above contacts of the conductors.

The document DE 1 0 201 1 08? 024 AI discloses an assembly with a ESektrakompanententräger and a Schalfvorrlchfung, The switching device of the assembly is here by means of at least one contact area of at least two Sfanzgitter conductor and a touch-magnetically displaceable Sehalfmedium the assembly by means of which Konfakfbereiche different Stanzgitfer-Leifer are selectively bridged, t , The intended to form a Schaitfunktionalifäf contact areas are exposed on a surface of the carrier and thus can be painted over from the Schaitm.edtum on the support surface or köhtaktiert and this be selectively bridged. Depictions of the Schaitvarrich-tung are de fek available.

The document DE 1 0 2004 040 395 AI discloses an electrical switch for a motor vehicle ^' mi two tracks and one above the tracks angeord Neten Schaitkonfakt in the form of a deformable snap disc, the Schaiikontakf contacted permanently electrically one of the two tracks. By operating the switch the Schaifkontökt is deformed and thereby electrically connected to the other conductor.

DE 10 2006 024 292 A I discloses a handle for the electrical actuation of a closure on a flap or a door in a vehicle. One . Punching grid is integrated in an electrocomponent carrier, which serves as an insert in the housing mold during the injection molding of the bowl-shaped gilding housing. The Eiekfrokornponenfenfräger has at its inner end a scharfarfige recording, which serves for inserting a deformable snap disk. The snap-action disk is part of an electrical switch in order to electrically connect normally closed contacts with one another.

Unless otherwise stated below, the abovementioned features may be combined as desired individually or in any combination with the object of the invention described below.

It is an object of the invention to provide an advanced egg white component fencer _. which in particular also allows a Defekfion the position of the micro-scarf. To solve the problem, a Eiektrokomponen tenfräger is provided with a Basis table of electrically insulating material and electrical conductors for connecting electrical components, which conductor tracks are enveloped by the material of the Basisistifs ^' . At least three electrical tracks of Elekfrbko ponenfenfrägers are an immediate part of an electrical Mikroschaiters. The ikroschaifer samtl an arcuate Leitereiement which is elastically deformable. By pressing the microswitch, the arcuate conductor element is elastically distributed in such a way that the two end portions of the conductor element are displaced. By moving two electrical conductors are electrically connected or an electrical connection between two conductors is interrupted. The shifting causes aiso an electrical switching.

By the invention, an electrical Sc age must not be soldered with protruding contacts of Eiektrokompon@ententra.gers. Tracks that an El.ektroko.mponen-th carrier already includes are an integral part of the electrical switch, the Hersteilungsaufwand is correspondingly low. By at least three electrical traces are part of the Schaher, the position of the switch can be detected in a simple manner. The switch is very simple and therefore robust and durable.

In an advantageous embodiment of the invention, four tracks are present, which are an integral part of the switch, in the idle state, that is, in the non-actuated States of the switch, kontafcfierf the arcuate conductor element advantageously two internal tracks, inside Siegende tracks ^' are those that are located between two further tracks of the microschaiter. If the switch is actuated, this will cause dg-ss no longer the two internal tracks electrically This can be used, for example, for detecting the position of the microshifter.

The Leiferbahn sections of the Mikroschaiters, the of the arcuate Leiferelernef k.an fak.fi he! can be advantageously parallel to each other, so as to minimize the required space.

The micro-creator embraces in one embodiment a cap or lid with a central region and an adjoining region of deformable Kunstsfoff aterlal, The central region transmits upon actuation of the microshifter such a force on the arcuate conductor element that this sic h deformed in the aforementioned manner In one embodiment of the invention, the areas of the tracks that may be contacted by the arcuate conductor element terminate flush with the adjacent surface, at least with the surface, resting on the ends of the arcuate conductor element or on the ends of the arcuate guide belt by pressing the switch rest. Hereby advantageously the force is kept low, which has to be expended for actuating the switch.

In one embodiment of the invention, the switch comprises guiding means and / or position means for guiding and / or positioning the arcuate conductor element.

In one embodiment of the invention, there is a pin protruding from the surface of the electrocomponent carrier that extends through a hole in the arcuate gripper belt. This P.asifionsrnittei is technically simple way to ensure that the arcuate Leitereiement maintains its position relative to the tracks. In an advantageous embodiment of the invention, the two ends of the curved Leifereiements are guided by adjacent webs. Faulty movements are thus avoided. In one embodiment of the invention, the ends of the arcuate Leifereiements are bent and opposite to the other arc shape of the arcuate Leif ereiements, This Reibungswiäerstände are kept low, which occur during the Beförigs of the croupier.

An Elekfrofcom planet carrier with the Mlkrosehaher ka n and should be electrically connected to at least two other electrical components. This distinguishes one

Electrode component carrier of a microswitch which is not an integral part of an electrocomponent interrogator. Examples of further components in the context of the present invention are one or more sensors or detectors, one or more motors, one or more wide microscopes. Also, the Eiekfrokomponententräger supports in addition to the tracks, the immediate part of the integrated. ikroscholters are, more. Tracks on.

Figures 1 to 4 illustrate the structure of an electrical component tether 1 with a base part 2 of electrically insulating Matena! and electrical interconnects 3, 4, 5. The interconnects 3, 4, 5 are partially by the material of the ßaslsfells

2 wrapped. Four electrical conductors 5 of the Elektrokomponentehtrögers 1 are direct Bes part of an electric micro _. sohglters. The Mikroschgl it comprises an arcuate Leitereiernent 6, which is elastically deformable. By pressing the Mik rose ha Hers the arcuate Leitereiernent 6 is elastically deformed such that the two end portions 7 of the Leitereiemen ts 6 are moved. Figure 4 shows in section the shifted and thus the actuated state, By moving the two end portions 7, the two electrical conductors 4 are electrically connected together. The electrical connection between the two interconnects 5, however, is interrupted by pressing. in the rest state of the holder C, the arcuate conductor core 6 kaks the two internal conductor tracks 5, like the figure

3 clarifies. These inner conductor tracks 5 are located between the two further Leiterbah NEN. 4 The Leiterfocshnabschnltfe the icroschalters, which are arranged between the two webs 8 and which can be kontakfierf of the arcuate conductor element 6, parallel to each other so as to minimize the space required. These sections or regions of the conductor tracks 4, 5 which are arranged between the two webs 8 and which can be contacted by the arcuate conductor element 6, terminate flush with their surface with the adjacent surface 9 of the insulating material. Moreover, the surfaces of the tracks 4, 5 are flush with the adjacent surface, as far as they are disposed within the protruding annular rim 10.

There is a pin 11 projecting from the surface of the electrocomponent carrier 1 and passing through the hole 12 in the arcuate conductor member 6 serving as a positional means. The two ends 7 of the arcuate conductor element 6 are guided by the laterally adjacent webs 8.

The ends 7 of the arcuate conductor element ό are bent and opposite to the other arc shape of the arcuate Leiterelemenfs 6. This creates arcuate support surfaces for the end regions 7, whereby frictional resistance is kept low - which occurs during the ßefäfigens of the microslicer 1.

The above edge tO serves for dust and moisture-proof fastening of the cover 13. The cover 13 is deformable, as the comparison of the figure with FIG. 3 illustrates. The interconnects 3 of the Eikktrokorrsponenienfrägers are not part of the Mikroschöschaliers. These are to be electrically connected to ^'another electrical component.

An inboard edge 1 4 of the lid Hegt on the arcuate Leitereiement 6 on. By pressing down the Deckenis 1 3, the arcuate Leitereiement 6 is pressed down hereby and the Mikroschaiter so operated. For pressing down an area 1 5 of the lid 1 3 is provided, which extends from the outside in the direction of the edge 1 4 cylindrical, i n the cylindrical shape, the pin 1 1 extends into it, which thus at the same time the leadership of the lid 1 3 serves. Seen from the region 1 5 extends the cover 1 3 wave-shaped (1 6) in the radial direction. As a result, the operation is facilitated.

FIGS. 5 and 6 show an embodiment of the invention with three interconnects of the micro-scaler. The interconnect 1 7 is widened in comparison to the interconnects 4 and 5, so that there is always contact with the arc-shaped conductive element 6. One of the two interconnects 3 or 4 can be used to detect or detect the position of the microslicer. But it is also possible to use both tracks 4 and 5 for switching.
