摘要:
The invention relates to a magnetic field sensor (13), particularly a rotary speed and/or rotational direction sensor for the wheel rotation or for the drivetrain of a motor vehicle, wherein an electrical component (10) and the end of a connecting cable (28) are encapsulated in plastic (32) by injection molding, and a mounting tab (38) is injection molded. The electrical component (10) and the end of the connecting cable (28) are encapsulated in plastic such that they form a core (30) whereon a mounting tab (38) is attached in a longitudinal and/or angular position that can be prescribed. Various positions of the core (30) relative to the mounting tab (38) can hereby be selected, so that the design of the magnetic field sensor can thereby be adapted to the installation conditions in a simple manner.

The invention relates to a movement sensor, particularly a rotational speed sensor for the wheel rotation of a motor vehicle, and to a method for producing a movement sensor. This movement sensor has an integrated circuit (32), which can be connected via an electric wire (24) and which has a measuring transducer and an electronic circuit arrangement for conditioning the measurement signals. The sensor comprises a basic module (10), which is produced by casting or injection molding thermoplastic material, preferably polyamide, using MID (Molded Interconnect Device) technology, and inside of which a permanent magnet (16) is integrated. A packageless integrated circuit (32) is mounted on the MID component using flip-chip technology. The arrangement consisting of the basic module (10), together with the integrated circuit (32) and the permanent magnet (16) as well as the connecting end of the wire (24) are, in another method step, enclosed by an outer encapsulation (42) and assembled to form a rugged modular unit that is well-protected from environmental influences.

The invention relates to a connection assembly (1) for a sensor assembly having a connection element (10) which is electrically and mechanically connected to one end (3.1, 4.1) of at least one wire (3, 4) of a connection cable (2) in a first contacting region (12) and can be electrically and mechanically connected to a sensor element in a second contacting region (16), wherein the connection element (10) is at least partially enclosed by a plastic overmold (20) which has a window-shaped recess (22) in a transition region (14) between the first contacting region (12) and the second contacting region (16) which is sealed in the injection moulding die during the injection process of the plastic overmold (20) and a corresponding sensor assembly. According to the invention, a positioning opening (15) is arranged in the transition region (14) such that the connection element (10) can be positioned in the injection moulding die and the transition region (14) surrounding the positioning opening (15) is sealed flat in the injection moulding die to create the window-shaped recess (22).
