Embodiment Construction

[0018] figure 1 The housing 2 is shown without a cover, in which an angular position sensor 4 is arranged. Holding means are provided to ensure good positioning of the sensor 4 within the housing 2 .

[0019] figure 1 The sensor 4 shown corresponds to a KMA 200 type magnetic converter-sensor. The sensor 4 has an approximately parallelepiped-shaped cell 8 . Protrusions 10 protrude from two opposite sides of the parallelepiped. The protrusion 10 generally serves to position the unit 8 of the sensor 4 in the housing 2 . Such sensors are known in the prior art.

[0020] The invention proposes a new means of holding the sensor 4 inside the housing 2 . figure 2 The device is shown in more detail.

[0021] figure 2 The shown retaining device 6 comprises a retainer plate 12 with a cutout 14 formed therein. Rigid bridges 16 providing support for the two bearing protrusions 18 are housed in the cutouts 14 and are connected to the holder plate 12 via U-shaped fixtures 20 .

Abstract

The invention relates to a holding device (6) for a sensor (4) or the same in a housing (2), that comprises: two bearing tabs (18) for interaction with said sensor (4); a rigid bridge (16) connecting the two bearing tabs (18); a holder (12) on which the rigid bridge (16) is mounted so that the rigid bridge (16) has a rotation freedom degree and a flexion freedom degree relative to the holder (12).

Description

technical field [0001] The invention relates to a device for holding a sensor. [0002] More specifically, the present invention relates to maintaining a magnetoresistive sensor within a housing. Magnetoresistive sensors include, for example, angle sensors in the automotive field. Such a sensor for measuring angular position can be found, for example, in US patent application document US 2003 / 0231015. Background technique [0003] In applications such as those described in the above-mentioned documents, the angle sensor is mounted in the housing. The sensors used in this document (for example KMA 200 type sensors) are non-contact sensors. It has holding tabs that extend on both sides of the unit forming the sensor itself. [0004] To hold such a sensor within the housing, pressure is usually applied directly on the sensor unit. An elastic pad is then placed between the housing cover and the sensor to hold the latter. The elastic element is able to absorb mechanical sho...
