Embodiment Construction

[0026] The present invention provides a temperature sensor device for sensing the temperature of a windshield of a vehicle, wherein the temperature sensor device includes a single non-flexible PCB and a temperature sensor mounted on the PCB. Non-flex PCBs (i.e. rigid PCBs) cannot be bent or rolled up significantly without damage. The bending radius of the PCB used here may in particular be smaller than 1 mm. The temperature sensor device includes a temperature sensor in thermal contact with the windshield through a thermal pad.

[0027] figure 1 An exemplary embodiment of a temperature sensor device 10 according to the invention is shown, as well as a cross-sectional view of the temperature sensor device 10 in the direction indicated by the arrow. PCB1 is packaged in case 2 . Some circuits 3 are formed on the PCB1. Circuit 3 includes circuit elements for data processing and sensor control.

[0028] The PCB includes a tab portion 1a. The temperature sensor 4 is attached t...

Abstract

The present invention relates to a temperature sensor device 10, 20 for sensing the temperature of a windshield 5 of a vehicle, the device comprising a single printed circuit board 1, 21 comprising a circuitry 3, 23, in particular, a measurement and control circuitry 3, 23, a temperature sensor 4, 24, in particular, a thermistor, mounted to the printed circuit board 1, 21, and a thermally conductive pad 6, 26 attached to the temperature sensor 4, 24 and arranged to thermally and mechanically directly contact the windshield 5.

Description

technical field [0001] The present invention relates to a temperature sensor device for sensing the temperature of a windshield of a vehicle, in particular, a temperature sensor device for sensing the temperature of a windshield of an automobile. Background technique [0002] It is known that temperature sensors, humidity sensors, optical sensors or combinations thereof can be used in windshield sensing devices installed in vehicles for automatic control of heating, ventilation, air conditioning and operation of windshield wipers. As an example, windshield temperature sensing devices are often used in anti-fog situations. [0003] In order to allow precise and reliable monitoring of the temperature and / or humidity of the vehicle windshield, the sensors of the sensing device must reliably maintain constant contact with the windshield surface throughout the lifetime of the vehicle, and therefore the sensor and its The connection to the windshield must be able to withstand mec...
