Abstract
The magnetic sensor device 3 comprises a sensor unit 4 and substrate-side connectors 24, 25. The sensor unit 4 comprises a magnetic sensor, a yoke, and a casing 19. The magnetic sensor comprises a magnetic wire rod that generates a large Barkhausen effect, a bobbin having the magnetic wire rod disposed therein, a coil formed by winding an electrical wire around the bobbin, a sensor-side connector provided in the left end portion of the bobbin, and a sensor-side connector provided in the right end portion of the bobbin. The magnetic sensor device 3 is provided on the substrate 35 by mounting the substrate-side connectors 24, 25 to the substrate 35 and, thereafter, connecting the sensor unit 4 to the substrate-side connectors 24, 25.
Claims6
A magnetic sensor device, comprising:
- a magnetic sensor, which comprises a magnetic wire rod that generates a Barkhausen effect, a bobbin having the magnetic wire rod disposed therein, a coil formed by winding an electrical wire around the bobbin, a first connector provided at one end of the bobbin, and a second connector provided at an other end of the bobbin, the magnetic sensor being provided on a substrate;
- a third connector detachably connected to the first connector;
- and
- a fourth connector detachably connected to the second connector,
- wherein the first connector comprises a first mating portion and a first terminal to which one end of the electrical wire is connected,
- the second connector comprises a second mating portion and a second terminal to which the other end the electrical wire is connected,
- the third connector comprises a third mating portion mated with the first mating portion and a third terminal making contact with the first terminal upon mating of the first mating portion with the third mating portion, and
- the fourth connector comprises a fourth mating portion mated with the second mating portion and a fourth terminal making contact with the second terminal upon mating of the second mating portion with the fourth mating portion,
- the third connector and the fourth connector are mounted on a surface of the substrate facing the bobbin.
