Abstract

A position sensor module ( 1 ) for control capsules ( 2 ), having a base carrier ( 3 ) which base carrier ( 3 ) has a first receiving space ( 4 ) in which is arranged a sensor chip ( 5 ) and a second receiving space ( 6 ) in which is arranged a plug contact strip ( 7 ) of a plug contact arrangement ( 8 ) which is connected to chip contacts ( 9 ) of the sensor chip ( 5 ), and a cover part ( 10 ) which covers the first receiving space ( 4 ) and the second receiving space ( 6 ). The cover part leaves open an access opening ( 11 ) to the plug contact strip ( 7 ), and fixes the sensor chip ( 5 ) and the plug contact arrangement ( 8 ) to the base carrier ( 3 ).

First claim

a second receiving space ( 6 ) in which is arranged a plug contact strip ( 7 ) of a plug contact arrangement ( 8 ) which is connected to chip contacts ( 9 ) of the sensor chip ( 5 ), and

a cover part ( 10 )
which covers the first receiving space ( 4 ) and the second receiving space ( 6 ), wherein said cover part leaves open an access opening ( 11 ) to the plug contact strip ( 7 ), and
which fixes the sensor chip ( 5 ) and the plug contact arrangement ( 8 ) to the base carrier ( 3 ),

wherein the cover part ( 10 ) is L-shaped correspondingly to the base carrier ( 3 ) and has two cover legs ( 20 , 21 ) which are arranged at least substantially perpendicular to one another and which cover the receiving spaces ( 4 , 6 ).

2. The position sensor module as claimed in claim 1 , wherein, in a connecting region ( 22 ) of the cover legs ( 20 , 21 ), a holding part ( 23 ) is arranged on the cover legs ( 20 , 21 ) at the inside, which holding part fixes the plug contact arrangement ( 8 ) to the base carrier ( 3 ).

3. The position sensor module as claimed in claim 1 , wherein the base carrier ( 3 ) and the cover part ( 10 ) are connected to one another by means of a suitable connecting device.

4. The position sensor module as claimed in claim 3 , wherein the base carrier ( 3 ) and the cover part ( 10 ) are connected to one another by means of a snap-action/latching connection, a screw connection, an adhesive connection or a welded connection.

5. The position sensor module as claimed in claim 1 , wherein the sensor chip ( 5 ) is a 3D Hall chip.

6. A position sensor module ( 1 ) for control capsules ( 2 ), having
a base carrier ( 3 ) with
a first receiving space ( 4 ) in which is arranged a sensor chip ( 5 ) and
a second receiving space ( 6 ) in which is arranged a plug contact strip ( 7 ) of a plug contact arrangement ( 8 ) which is connected to chip contacts ( 9 ) of the sensor chip ( 5 ), and

a cover part ( 10 )
which covers the first receiving space ( 4 ) and the second receiving space ( 6 ), wherein said cover part leaves open an access opening ( 11 ) to the plug contact strip ( 7 ), and
which fixes the sensor chip ( 5 ) and the plug contact arrangement ( 8 ) to the base carrier ( 3 ),

wherein the base carrier ( 3 ) has a guide arrangement ( 14 ) which receives and guides the chip contacts ( 9 ).

7. A position sensor module ( 1 ) for control capsules ( 2 ), having
a base carrier ( 3 ) with
a first receiving space ( 4 ) in which is arranged a sensor chip ( 5 ) and
a second receiving space ( 6 ) in which is arranged a plug contact strip ( 7 ) of a plug contact arrangement ( 8 ) which is connected to chip contacts ( 9 ) of the sensor chip ( 5 ), and

a cover part ( 10 )
which covers the first receiving space ( 4 ) and the second receiving space ( 6 ), wherein said cover part leaves open an access opening ( 11 ) to the plug contact strip ( 7 ), and
which fixes the sensor chip ( 5 ) and the plug contact arrangement ( 8 ) to the base carrier ( 3 ),

wherein the base carrier ( 3 ) is L-shaped and the first receiving space ( 4 ) is arranged in a first carrier leg ( 12 ) and the second receiving space ( 6 ) is arranged in a second carrier leg ( 13 ) which is arranged at least substantially perpendicular to the first carrier leg ( 12 ), and
wherein the base carrier ( 3 ) has support portions ( 15 , 16 ) which are arranged on the carrier legs ( 12 , 13 ) and which project from associated leg surfaces ( 17 , 18 ) and which are arranged adjacent to one another.

8. A position sensor module ( 1 ) for control capsules ( 2 ), having
a base carrier ( 3 ) with
a first receiving space ( 4 ) in which is arranged a sensor chip ( 5 ) and
a second receiving space ( 6 ) in which is arranged a plug contact strip ( 7 ) of a plug contact arrangement ( 8 ) which is connected to chip contacts ( 9 ) of the sensor chip ( 5 ), and

a cover part ( 10 )
which covers the first receiving space ( 4 ) and the second receiving space ( 6 ), wherein said cover part leaves open an access opening ( 11 ) to the plug contact strip ( 7 ), and
which fixes the sensor chip ( 5 ) and the plug contact arrangement ( 8 ) to the base carrier ( 3 ),

wherein the plug contact arrangement ( 8 ) is L-shaped and has a chip contact strip ( 19 ) which is arranged at least approximately perpendicular to the plug contact strip ( 7 ).

9. A position sensor module ( 1 ) for control capsules ( 2 ), having
a base carrier ( 3 ) with
first receiving space ( 4 ) in which is arranged a sensor chip ( 5 ) and
a second receiving space ( 6 ) in which is arranged a plug contact strip ( 7 ) of a plug contact arrangement ( 8 ) which is connected to chip contacts ( 9 ) of the sensor chip ( 5 ), and

a cover part ( 10 )
which covers the first receiving space ( 4 ) and the second receiving space ( 6 ), wherein said cover part leaves open an access opening ( 11 ) to the plug contact strip ( 7 ), and
which fixes the sensor chip ( 5 ) and the plug contact arrangement ( 8 ) to the base carrier ( 3 ),

further comprising a holding clip ( 24 ; 25 ; 26 ; 27 ) which has a first fastening region ( 24 A; 25 A; 26 A; 27 A) for holding the module ( 1 ) and a second fastening region ( 24 B; 25 B; 26 B; 27 B) for fixing to the control capsule ( 2 ).
