Sensor unit for a vehicle
A sensor arrangement for a vehicle includes a sensor unit, a cable arrangement, and an elastic cap. The sensor unit has a main support, an electronics part connected to the main support, and a sensor element. The cable arrangement has at least one individual wire, and is configured to electrically contact the electronics part via at least one contact-making member. The main support is an open housing defining at least one insertion opening configured to accommodate the at least one contact-making member and an accommodation pocket configured to at least partially accommodate the electronics part. The elastic cap has a member configured to fasten the sensor unit in the vehicle, is configured to be pushed at least partially over the main support, and closes off the accommodation pocket in a sealed manner.
1. A sensor arrangement for a vehicle comprising:
a sensor unit including:
a main support;
an electronic part having a sensor element, the electronic part being connected to the main support; and
an open housing that defines a plurality of insertion openings and a receiving pocket configured to at least partially receive the electronic part;
a cable arrangement including a plurality of single conductors, each single conductor including a respective seal axially mounted thereon and corresponding to a respective one of the plurality of insertion openings;
an elastic cap including a fastening mechanism to screwlessly fasten the sensor unit in the vehicle, the elastic cap being configured to be pushed at least partially over the main support, and close the receiving pocket in a sealing fashion; and
a plurality of contact-making devices configured to electrically connect the cable arrangement to the electronic part, a respective contact-making device corresponding to and inserted with an end of each single conductor into the respective one of the plurality of insertion openings such that each of the plurality of insertion openings is sealed via the respective seal of each single conductor.
2. The sensor arrangement as claimed in claim 1 , wherein the main support includes a synthetic material injection molded part having a positioning lug.
3. The sensor arrangement as claimed in claim 1 , each of the contact-making devices including at least one first contact site configured to contact the electronic part and at least one second contact site configured to contact the cable arrangement.
4. The sensor arrangement as claimed in claim 3 , wherein at least one of (i) the at least one first contact site has a welded connection, and (ii) the at least one second contact site includes a crimped connection.
5. The sensor arrangement as claimed in claim 1 , wherein the fastening mechanism of the elastic cap includes a stop surface configured in an assembled state to be positioned on an edge of an assembly opening of an assembly region of a vehicle.
6. The sensor arrangement as claimed in claim 1 , wherein the fastening mechanism of the elastic cap includes an outwardly open receiving groove configured in an assembled state to encompass an edge of an assembly opening of the vehicle in an assembly region.
7. The sensor arrangement as claimed in claim 1 , wherein:
the elastic cap includes an internal sealing surface,
the main support includes a sealing bead arranged on the main support, and
the internal sealing surface and the sealing bead define an internal sealing region.
8. The sensor arrangement as claimed in claim 1 , wherein the elastic cap includes an external sealing lip which, together with a corresponding surface of an assembly opening of the vehicle, is configured to define an external sealing region that seals the assembly opening.
