Abstract
The present invention relates to a temperature sensor (1) for an engine of a vehicle, comprising: a casing (1) containing a circuit board (14) and traversed by at least one pair (2) of wires (3) provided with terminals (8), the terminal (8) being made up of a portion (804) crimped onto a conductor (5) arranged in the casing (1), a connector (101) comprising at least one metal insert (10) ensuring the electrical connection with the circuit board (14), where the casing comprises at least one flange (9) for holding the terminals (8), the terminals (8) being folded.
Claims10
A temperature sensor for an engine of a vehicle, comprising:
- a casing containing a circuit board and traversed by at least one pair of wires provided with terminals, each terminal being made up of a portion crimped onto and above a conductor arranged in the casing, a connector comprising at least one metal insert ensuring the electrical connection with the circuit board,
- wherein the casing comprises at least one flange for holding the terminals, the terminals being folded, and
- wherein a seal is arranged in an empty space formed by the at least one flange and the casing, the seal ensuring complete tightness between the conductor and an insulation formed on the at least one pair of wires,
- wherein no humidity passes via the at least one pair of wires, by capillary action between strands of the conductor and the insulation.
A method for production of a temperature sensor for an engine of a vehicle, the method comprising:
- during assembly of the temperature sensor, inserting terminals of at least one pair of wires straight into a casing;
- and
- folding the terminals directly inside the casing using a folding tool,
- wherein the temperature sensor comprises the casing containing a circuit board and traversed by the at least one pair of wires provided with the terminals, the terminals being made up of a portion crimped onto and above a conductor arranged in the casing, a connector comprising at least one metal insert ensuring the electrical connection with the circuit board,
- wherein the casing comprises at least one flange for holding the terminals,
- wherein a seal is arranged in an empty space formed by the at least one flange and the casing, the seal ensuring complete tightness between the conductor and an insulation formed on the at least one pair of wires,
- wherein no humidity passes via the at least one pair of wires, by capillary action between strands of the conductor and the insulation.
