Abstract
A magnetic sensor comprises a sensor package and a magnet. The sensor package includes a plurality of lead frames, a magnetic sensor element, and an encapsulation. The plurality of lead frames include a first outer lead and a second outer lead. The first outer lead has a first body and a first protrusion. The second outer lead has a second body and a second protrusion. The magnet includes a magnet body, a first restricting portion, a second restricting portion, a first receiving portion, and a second receiving portion.
Claims5
A magnetic sensor comprising:
- a sensor package;
- and
- a magnet surrounding a portion of the sensor package and having a shape allowing the sensor package to be inserted into the magnet,
- the sensor package including:
- a plurality of lead frames;
- a magnetic sensor element connected to any one of the plurality of lead frames and sensing a change in a magnetic field generated by the magnet;
- and
- an encapsulation that encapsulates the plurality of lead frames and the magnetic sensor element so as to expose a portion of the plurality of lead frames,
- the plurality of lead frames including:
- a first outer lead exposed from the encapsulation and disposed at an end located on one side in a direction orthogonal to an inserting direction in which the sensor package is inserted into the magnet;
- and
- a second outer lead exposed from the encapsulation and disposed at an end located on an other side in the orthogonal direction,
- the first outer lead having:
- a first body having a shape extending in the inserting direction;
- and
- a first protrusion protruding from the first body outward in the orthogonal direction,
- the second outer lead having:
- a second body having a shape extending in the inserting direction;
- and
- a second protrusion protruding from the second body outward in the orthogonal direction,
- the magnet including:
- a magnet body surrounding at least a portion of the encapsulation;
- a first restricting portion that restricts the first body displacing relative to the magnet body outward in the orthogonal direction;
- a second restricting portion that restricts the second body displacing relative to the magnet body outward in the orthogonal direction;
- a first receiving portion that receives the first protrusion on a side opposite to the inserting direction;
- and
- a second receiving portion that receives the second protrusion on the side opposite to the inserting direction.
