Embodiment Construction

[0049] figure 1 A perspective view of a temperature sensor 1 according to an embodiment of the invention is depicted before being mounted on an engine interface element 9 .

[0050] Temperature sensors are used to measure the temperature of exhaust gases from motor vehicles. The sensor is also used to measure the temperature of on-board fuel (ethanol, methane) heating and reforming units of fuel cell vehicles.

[0051] Temperature sensors are primarily used to measure so-called average temperatures between -40°C and 1100°C.

[0052] This temperature sensor 1 comprises at its one end a thermal part exposed to very high temperatures.

[0053] The thermal assembly contains:

[0054] - In the case of resistive sensors, (PTC (Positive Temperature Coefficient) / NTC (Negative Temperature Coefficient)) thermistor type sensitive elements,

[0055] - In the case of the sensor, the thermal junction of the thermocouple wires.

[0056] The sensor also includes: two wires 3 connecting t...

Abstract

The present invention relates to a temperature sensor (1) for a motor vehicle. The temperature sensor (1) comprises a temperature-sensitive element, two electric wires (3) connecting the temperature-sensitive element to an electrical connector, an insulating sheath (5) surrounding the two electric wires (3), a protective end piece comprising a closed end in which the temperature-sensitive element is housed, and a fixing means (6) through which the insulating sheath (5) passes. The fixing means (6) comprises a threaded element (8) intended to be screwed into a threaded orifice (7) provided in an engine interface element (9) of the vehicle so as to fix the temperature sensor (1) to the engine interface element (9), and a stop (10) fixed to the insulating sheath (5). The stop (10) surrounds the insulating sheath (5) and is intended to provide sealing between the inside of the engine interface element (9) and the outside, and the threaded element (8) is able to turn relative to the stop (10). According to the invention, the stop (10) comprises at least one lug (11) intended to be inserted into a slot (12) provided in the engine interface element (9) to block the rotation of the temperature sensor (1) with respect to the engine interface element (9).

Description

technical field [0001] The invention relates to a temperature sensor, in particular a temperature sensor for measuring temperatures between -40°C and 1100°C. [0002] The invention applies in particular to temperature sensors suitable for measuring the temperature of exhaust gases of motor vehicles. [0003] The present invention also applies to temperature sensors used in on-board fuel (ethanol, methane) heating and reforming devices of fuel cell vehicles. Background technique [0004] These sensors typically include a thermal element, such as a thermistor or thermocouple, connected by wires to an external electrical / electronic measurement signal utilization circuit. [0005] Such prior art temperature sensors include at one end a thermal part that is exposed to very high temperatures. [0006] The thermal assembly includes: [0007] - In the case of resistive sensors, (PTC (Positive Temperature Coefficient) / NTC (Negative Temperature Coefficient)) thermistor type sensiti...
