Temperature sensor, manufacturing process and corresponding method of assembly

A method of assembling a temperature sensor for an engine compartment of an automotive vehicle into a corresponding cavity, the temperature sensor comprising a temperature-sensitive element and a peripheral envelope receiving the temperature-sensitive element at a closed end, the peripheral envelope being inserted in the corresponding cavity, the method comprising:

• assembling the temperature sensor into the corresponding cavity in a first direction so as to position a flexible assembly stop of the closed end of the peripheral envelope facing a bottom of the corresponding cavity;
• and
• deforming projecting walls of the flexible assembly stop outwardly and at least partially in a second direction towards a peripheral portion of the closed end of the peripheral envelope by shape cooperation between the flexible assembly stop and the bottom of the corresponding cavity,
• wherein the first direction is substantially opposite to the second direction.
