Embodiment Construction

[0021] FIG. 1 shows a sensor 10 according to the invention, comprising a housing part 12 , two fixing parts 14 and a fixing device 16 .

[0022] The fastening device 16 is designed as a plate-shaped part with a central opening so that it can accommodate the housing part 12 in a collar-like manner. The fastening device 16 has webs 19 laterally, on which pins 20 are arranged, which extend laterally outwards. The connecting plate 19 extends substantially perpendicularly to the window pane 18 , so that the position of the pin 20 is approximately parallel to the window pane 18 . The fastening device 16 is glued to the inner side of the window pane 18 and is produced in one piece.

[0023] The housing part 12 is made of a bowl-shaped plastic part and has recessed formations 23 parallel to the window pane 18 in which the fastening elements 14 can be accommodated. Likewise, housing part 12 has a socket 22, which is a sensing element 21 ( Figure 5 ) with a communication interface wi...

Abstract

A sensor for optical detection of foreign bodies, in particular raindrops, on a window, in particular on the windshield of a motor vehicle, having a sensor element that is coupled to the inside of the window and having a fastening device, which is glued to the window, wherein the housing part has a fastening part pivotably attached to it, which can be brought into engagement with the fastening device by the clamping tension.

Description

technical field [0001] The invention relates to a sensor for the optical detection of foreign bodies, in particular raindrops, on a window pane, in particular a motor vehicle windshield. Background technique [0002] DE 4410217 A1 already discloses a sensor with several housing parts. In this sensor, a fixture is glued to a window pane. Two slides guided in an outer housing act as fastening means to engage the outer housing part with the fastening device. The sensor element is mounted on an inner housing part which is pressed against the pane by means of a spring force acting on the outer housing part. This fixing method is cumbersome, time-consuming, susceptible to interference, and thus high in cost. Contents of the invention [0003] According to the invention, a sensor is proposed for the optical detection of foreign bodies, in particular raindrops, on a window pane, in particular a motor vehicle windscreen, having a sensor element which can be coupled to the inner ...
