The invention concerns a temperature probe (1) comprising a thermistor provided with a heat-sensitive element connected to two electrically-conductive output wires, two electrically-conductive metal blades presenting proximal end portions connected, by welding, to the respective output wires and supporting said heat-sensitive element at a distance from said proximal end portions, and a plunger body (5) made in a plastic material overmolded by injection at least around the proximal end portions of the blades, of the output wires and of the heat-sensitive element, said plunger body presenting an end portion (50) overmolded directly all around the heat-sensitive element, said heat-sensitive element being wrapped only by said plunger body. The present invention finds application in the field of temperature measurement of a fluid circulating within a combustion engine.
A temperature probe comprising a thermistor provided with a heat-sensitive element connected to two electrically-conductive output wires, said temperature probe configured to be immersed into a fluid and measure a temperature thereof, wherein said temperature probe comprises two electrically-conductive metal blades presenting proximal end portions connected by welding to the respective electrically-conductive output wires and supporting said heat-sensitive element at a distance from said proximal end portions, and wherein said temperature probe further comprises a plunger body made of a plastic material overmolded by injection at least around the proximal end portions of the electrically-conductive metal blades, the electrically-conductive output wires and the heat-sensitive element, said plunger body presenting an end portion overmolded directly all around the heat-sensitive element, said heat-sensitive element being wrapped only by said plunger body, said plunger body configured to plunge into the fluid,
A method for manufacturing a temperature probe, said temperature probe configured to be immersed into a fluid and measure a temperature thereof, the method comprising the following steps of:
