Abstract

A measuring sensor for a motor vehicle, including a body and an electronic measurement module having an integrated circuit for measurement management and a plurality of connection pins that are able to be linked to an electrical communication network of a motor vehicle. The sensor includes an electrical component carrier to which an electrical component is fastened, the component having a first connection wire, connected electrically to a first portion of a first connection pin of the plurality of connection pins of the electronic measurement module and a second connecting wire, connected electrically to a second portion of a second connection pin of the plurality of connection pins of the electronic measurement module.

First claim

The invention claimed is:

1. A measurement sensor for a motor vehicle, said sensor comprising:
a body and
an electronic measurement module, said electronic measurement module comprising:
an integrated circuit for measurement management and
a plurality of connection pins that are able to be linked electrically to a communication network of a motor vehicle,

said body comprising:
a base for fastening the sensor in the motor vehicle and
an element for receiving the electronic measurement module, made from material of the base, comprising a first cylindrical portion delineating a reception space in which said electronic measurement module is mounted and a second cylindrical portion for linking the reception element to the base, the first cylindrical portion comprising means for receiving an electrical component carrier,

said sensor furthermore comprising an electrical component carrier mounted in said means for receiving and to which a two-wire electrical component is fastened, said two-wire electrical component comprising a first connecting wire, connected electrically to a first portion of a first connection pin of the plurality of connection pins of the electronic measurement module, and a second connecting wire, connected electrically to a second portion of a second connection pin of the plurality of connection pins of the electronic measurement module.

2. The sensor as claimed in claim 1 , said sensor furthermore comprising a protective overmolding over the electronic measurement module, completely enveloping the element for receiving the electronic measurement module.

3. The sensor as claimed in claim 1 , said sensor furthermore comprising a seal made from a material of the second cylindrical portion.

4. A motor vehicle comprising a sensor as claimed in claim 1 .

5. The sensor as claimed in claim 1 , wherein the electrical component carrier comprises a base from which two tabs for holding the electrical component extend.

6. The sensor as claimed in claim 5 , wherein the electrical component carrier comprises two ribs for guiding the carrier in the grooves, said ribs being positioned on either side of the base.

7. A method for manufacturing a sensor as claimed in claim 1 , said method comprising:
a step of mounting the electronic measurement module in the reception space,
a step of mounting a two-wire electrical component on the two-wire electrical component carrier,
a step of inserting said electrical component carrier into the reception means of the first cylindrical portion, such that the first connecting wire of the electrical component comes into contact with a first portion of a first connection pin of the plurality of connection pins of the electronic measurement module and that the second connecting wire of the two-wire electrical component comes into contact with a second portion of a second connection pin of the plurality of connection pins of the electronic measurement module,
a step of soldering said first connecting wire to said first portion and said second connecting wire to said second portion.

8. The method as claimed in claim 7 , said method furthermore comprising a step of overmolding the reception element with a thermoplastic material.

9. The sensor as claimed in claim 1 , wherein the reception means comprise two grooves into which the electrical component carrier ( 140 ) is inserted.

10. The sensor as claimed in claim 9 , wherein the electrical component carrier comprises a base from which two tabs for holding the electrical component extend.

11. The sensor as claimed in claim 9 , wherein the electrical component carrier comprises two ribs for guiding the carrier in the grooves, said ribs being positioned on either side of the base.

12. The sensor as claimed in claim 11 , wherein the ribs comprise, at one end, a curved wall enabling the connecting wires of the electrical component to be shaped against the pin portions so as to ensure the effective electrical connection thereof.
