The present invention relates to a device for contacting a direction-dependent electrical and/or electronic component, and to a corresponding component system having such a contacting device.
Currently, a housing for a component, including connection assignment (pinning), is selected taking into account size (costs), short bonding lengths, and testability. In order to create layouts that are to be used by a maximum number of clients having differing requirements, nowadays a very large number of assembly positions must be kept available on the circuit board. However, this quickly runs up against limits due to the limited available surface. In addition, there are further component-specific requirements. For sensors, vibrations/resonances play a large role, and these additionally change as a function of the location of installation or screw-on points, both of an electronic control unit (ECU) and of the circuit board and the desired direction of detection.
In German Published Patent Appln. No. 10 2009 042 653, for example, a method is described for the automatic assembly of substrates and components in assembly devices, the components and/or individual circuits that are to be assembled being predetermined by an assembly program. However, for the assembly of a substrate there may exist a plurality of possible assembly variants. For this reason, each substrate that is to be assembled is provided with an individual identifier. In addition, a list of the possible assembly variants and configurations is stored for a circuit board description. In the assembly device, the individual assembly variant and configuration for the respective substrate is then determined on the basis of this individual substrate identifier, and is specified to the assembly program of the assembly device. Standardly, the assembly program defines a sequence for carrying out the assembly of the substrate, starting from a description for the respective assembly, the so-called circuit board description, including for example a configuration of the substrate to be assembled, descriptions of the components used, etc.
In contrast, a device according to the present invention for contacting a direction-dependent electrical and/or electronic components, and the corresponding component system, has the advantage that through the use of a connection assignment (pinning) that is rotationally symmetrical about 90°, in the case of direction-dependent components, the flexibility and the degree of freedom can be massively increased in which the components or the electronic control unit (ECU) can be used. In addition, layout surface can be saved, or an optimized position can be used more simply. In connection with the present invention, pinning is to be understood as the assignment of component-based functions to the first connecting elements of the component.
Specific embodiments of the present invention make it possible for a client to use a standard layout for a plurality of cases of application having different directions of detection, so that for example a rotational rate sensor can also be used for a rollover functionality. Because control device plug connectors may be oriented in different directions for different clients, in the standard layout a second assembly place must be kept available for the direction-dependent electrical and/or electronic component. These places kept available multiply in number when one takes into account that the clients additionally use different screw-on positions for a corresponding electronic control unit (ECU), with the result that the direction-dependent electrical and/or electronic component must be situated at the right or at the left on the circuit board. Of the four installation positions, in the case of a direction-dependent electrical and/or electronic component having a contacting device rotatable by 90°, it is already possible to save two available places.
Specific embodiments of the present invention provide a device for contacting a direction-dependent electrical and/or electronic component that includes a predetermined first number of functions that are to be contacted, the device including a basic body and a predetermined first number of first contact elements that are each assigned to a function that is to be contacted in accordance with a predetermined connection assignment, and that are situated on the basic body with a predetermined positioning. According to the present invention, the positioning of the first contact elements on the basic body is made to be rotationally symmetrical about an angle of 90°, so that when there is a rotation of the direction-dependent electrical and/or electronic component by 90°, no different component-based functions will lie against one another.
Specific embodiments of a component system according to the present invention include a direction-dependent electrical and/or electronic component that includes a predetermined first number of functions that are to be contacted, and a component bearer that has a predetermined layout having a predetermined second number of second contact elements. The direction-dependent electrical and/or electronic component includes a contacting device according to the present invention having a basic body and a plurality of first contact elements that are respectively assigned to a function that is to be contacted according to a predetermined connection assignment, and are situated on the basic body with a predetermined positioning. According to the present invention, the positioning of the first contact elements on the basic body is made rotationally symmetrical about an angle of 90°, so that when there is a rotation of the direction-dependent electrical and/or electronic component by 90°, no different component-based functions lie against one another.
Exemplary embodiments of the present invention can be used in all areas in which the orientation of components plays a role, as is the case for example for direction-sensitive sensors such as rotational rate sensors and/or acceleration sensors. The possible uses of such components multiply given the use of a rotationally symmetrical pinning. The component bearer can for example be realized as a circuit board or substrate.
It is particularly advantageous that the basic body can be realized as a part of the component housing or as a component base. This enables a simple implementation of the present invention. As a function of the component housing or of the installation situation, the basic body can for example be made circular or rectangular, and the number of first contact elements can correspond to the first number of functions to be contacted.
In the realization of the contacting device as a component base into which the component is plugged, the connection assignment, or assignment of the first contact elements to the functions of the component that are to be contacted, can advantageously be adapted in such a way that the corresponding direction-dependent electrical and/or electronic component can be placed onto the component bearer both in a 0° orientation and in a 90° orientation. In this way, it is advantageously possible to correspondingly adapt conventional sensor types known from the existing art in order to make it possible to achieve the rotational symmetry.
In an advantageous embodiment of the component system according to the present invention, the second number of second contact elements is selected to be at least twice as large as the first number of first contact elements, a first contact element being capable of being connected to two second contact elements in each case.
In a further advantageous embodiment of the component system according to the present invention, the first contact elements are realized as connecting pins and the second contact elements are realized as pin receptacles.
In a further advantageous embodiment of the component system according to the present invention, the second contact elements are situated on the component bearer in such a way that the direction-dependent electrical and/or electronic component, in a first position having a first detection direction or in a second position having a second detection direction, can be contacted to the component bearer, the second detection direction having an angle of 90° to the first detection direction.
In a further advantageous embodiment of the component system according to the present invention, a first contact element of the direction-dependent electrical and/or electronic component is realized as an orientation element that, in the first position, is contacted to a second contact element that is connected to a first electrical potential, and in the second position is connected to a different second contact element that is connected to a second electrical potential, the current orientation of the direction-dependent electrical and/or electronic component, and thus the current direction of detection, being capable of being determined by querying the electrical potential present at the orientation element. This advantageously enables a simple automatic recognition of an unintentional misassembly, i.e. installation of the direction-dependent electrical and/or electronic component with the wrong orientation. Thus, the one second contact element can for example be connected to ground potential and the other second contact element can for example be connected to a supply voltage potential. If, now, the direction-dependent electrical and/or electronic component is assembled in the first direction of detection, then the corresponding first connecting element is connected to the ground potential. If the direction-dependent electrical and/or electronic component is assembled rotated by 90°, then the corresponding first connecting element is connected to the supply voltage potential. Thus, the direction-dependent electrical and/or electronic component can either itself recognize in which direction it has been installed, or the information can be handed over, via a further connecting element, to an evaluation and control unit that correspondingly processes the information. Alternatively, the orientation of the direction-dependent electrical and/or electronic component can take place by automatic optical inspection (AOI), via an imprint made on the direction-dependent electrical and/or electronic component.
The pinning of the corresponding contacting device, or of the direction-dependent electrical and/or electronic component, can be adapted, through specific embodiments of the present invention, in such a way that the direction-dependent electrical and/or electronic component can be assembled on the component bearer both in a 0° orientation and in a 90° orientation. The pinning of the corresponding contacting device fulfills the conditions of rotational symmetry if, when there is a rotation by 90°, no two different component-based functions lie against one another.
An exemplary embodiment of the present invention is shown in the drawings and is explained in more detail in the following description. In the drawings, identical reference characters designate components or elements that execute identical or analogous functions.

Here, an exception is formed by second contact elements 33 of component bearer 30, which can be used for the automatic determination of the orientation of the assembled direction-dependent electrical and/or electronic component 10. For this purpose, a first contact element 23 of direction-dependent electrical and/or electronic component 10, situated on contacting device 20 at raster position H8, is used as orientation element 18.1. In addition, second contact element 33, situated on component bearer 30 at raster position H1, is connected to a ground potential, and second contact element 33, situated on component bearer 30 at raster position H8, is connected to a supply voltage potential. If, now, direction-dependent electrical and/or electronic component 10 is assembled in first direction of detection X, then the corresponding first connection element 23 situated at raster position H8 of contacting device 20 is connected to second contact element 33, situated at raster position H8 of component bearer 30, and is thus connected to ground potential. If direction-dependent electrical and/or electronic component 10 is assembled rotated by 90°, then the corresponding first connecting element 23, situated at raster position H8 of contacting device 20, is connected to second contact element 33, situated at raster position H1 of component bearer 30, and thus is connected to the supply voltage potential. Through the different voltage potentials, which are a function of the position of installation of the direction-dependent electrical and/or electronic component, the direction-dependent electrical and/or electronic component 10 can either itself recognize the direction of detection in which it has been installed, or the information can be transferred via a further connecting element to an evaluation and control unit that correspondingly processes the information.
Alternatively, the orientation of direction-dependent electrical and/or electronic component 10 can take place by an automatic optical inspection via an imprint made on direction-dependent electrical and/or electronic component 10.
Specific embodiments of the present invention advantageously increase, through the connection assignment rotationally symmetrical about an angle of 90°, the flexibility and the degrees of freedom for direction-dependent components. In this way, standard layouts can be created that can be used by a maximum number of clients having different demands without having to keep available too many assembly positions on the circuit board.
