Embodiment Construction

[0028] figure 1 A sectional side view of a can-shaped bushing 1 for a sensor device is shown in . The sleeve 1 serves to accommodate electrical sensor components, not further shown here, and is provided with an annular bevel 5 on an inner wall 4 at an open end 3 remote from the bottom 2 . This bevel 5 is used to facilitate the insertion of the plunger during the production of the sensor device.

[0029] figure 2 A side view of the head 6 of the corresponding plunger is shown. The head 6 has a support 7 designed as an annular bead.

[0030] image 3 A cross-sectional side view of the first sensor device 8 is shown in . The sensor device 8 comprises a flange part 9 for externally fixing the sensor device 8 (for example on the chassis of a motor vehicle), and a sleeve 1 for receiving the sensor part (not further shown here). A sleeve 1 with a cylindrical contour 12 is designed as a tank with a closed bottom 2 and is arranged in an annular recess 10 of a flange part 9 . Bo...

Abstract

The invention relates to a sensor device (8) comprising: a flange part (9) for externally fastening the sensor device (8); a sleeve (1) fixedly connected to the flange part (9), Used to accommodate electrical components. The invention also relates to a method of manufacturing the sensor device (8). In order to simplify the manufacture of the sensor device, the invention proposes such a device that the sleeve (1) is arranged in the recess (10) of the flange part (9) and is connected to the flange part (9) by means of a friction weld (11). ) are connected. The recommended method includes the following steps: placing the flange part into the weld housing; inserting a cylindrical sleeve into the recess of the flange part with clearance; driving a plunger into the sleeve to expand the sleeve in the area of ​​the inner wall of the recess. pipe, wherein the sleeve and the flange part are radially extruded; and the sleeve and the flange part are relatively rotated relative to each other, thereby forming a friction weld of the sleeve and the flange part.

Description

technical field [0001] The invention relates to a sensor device having a flange part for fastening the sensor device from the outside and a sleeve fixedly connected to the flange part for accommodating electrical components. Furthermore, the invention relates to a method for producing a sensor device. Background technique [0002] A sensor device is known in the form of an inductive rotational speed sensor, which has a housing that accommodates electrical components, the housing has a first housing part, which is made of plastic during an injection molding process. The formed second housing part is partially surrounded, a tight connection being achieved in the contact region of the two housing parts. Arranged in the pot-shaped first housing part is a bobbin with a coil having contact pins and conductors. No flange part is provided for the external fastening of the rotational speed sensor. [0003] Furthermore, a device for detecting the rotational speed of a rotating part...
