Abstract

A tool for the primary shaping of a housing for a sensor which is designed to capture, via a sensing element, a physical area that is dependent on a variable to be measured, and to emit an electrical output signal on the basis of the captured physical area, including: —a mold cavity for receiving a material that molds the housing, and the sensing element, and —a box having a wall that bounds the mold cavity, wherein at least a part of the wall that bounds the mold cavity is mounted in a displaceable manner.

First claim

The invention claimed is:

1. A method for using a tool for producing a housing for a sensor that is configured so as to ascertain by way of a measuring element a physical field that is dependent upon a variable that is to be measured and to output an electrical output signal based upon the physical field that is ascertained, the tool comprising a molding cavity for receiving a material that forms the housing and the measuring element, and a box having a wall that delimits the molding cavity, at least one part of the wall that delimits the molding cavity being mounted in such a manner that it can be displaced, the method comprising:
placing the measuring element in the molding cavity,
introducing the material into the molding cavity,
moving the movable part of the wall, and
introducing a further material into the molding cavity during or after moving the movable part of the wall, the further material being identical to the material, the further material comprising a thermal energy when being introduced into the molding cavity, the material being at least in part melted by the thermal energy of the further material.

2. The method as claimed in claim 1 , wherein the displaceable part of the wall is embodied as a slider that is mounted in such a manner that it can move with respect to another part of the box.

3. The method as claimed in claim 2 , wherein the slider is a sliding block.

4. The method as claimed in claim 1 , wherein the molding cavity is configured so as to support the measuring element on the displaceable wall prior to introducing the material that forms the housing.

5. The method as claimed in claim 1 , wherein the material is a thermoplastic.

6. A sensor for ascertaining by way of a measuring element a physical field that is dependent upon a variable that is to be measured and for outputting an electrical output signal based upon the physical field that is ascertained comprising a housing that is produced by the method in accordance with claim 1 .
