Sensor with resin encapsulated terminal separation
View Patent ↗A sensor includes: a sensing module furnished with a sensing function; metal terminals transmitting a sensing signal from the sensing module; an insulating fixing portion holding multiple metal terminals separately; and a resin portion encapsulating the metal terminals and the sensing module and also forming a connector portion from which tip ends of the metal terminals are exposed. Protruding portions of the fixing portion are fit into hole portions of the metal terminals before resin encapsulation in a stage where the metal terminals are bonded to the sensing module, so that rigidity of the metal terminals is enhanced to stabilize the locations thereof.
1. A sensor with resin encapsulated terminal separation, the sensor comprising:
a sensing module furnished with a sensing function;
metal terminals shaped of a capital L which transmit a sensing signal from the sensing module, each of the metal terminals comprising a first linear portion connected to the sensing module and a second linear portion which is bent from the first linear portion, each of respective second linear portions comprising a tip;
a fixing portion which is spaced apart from the tips of respective metal terminals and to which the first linear portions of the respective metal terminals are separately attached proximate the sensing module; and
a resin portion, which encapsulates the fixing portion, the metal terminals, and the sensing module, and forms a connector portion, from which ends of the tips of the respective metal terminals are exposed,
wherein the tips of the second linear portions of the metal terminals protrude in a first direction, the first linear portions have an upper side proximate the fixing portion and a lower side opposing the upper side as seen in the first direction, and
the fixing portion comprises:
a planar portion which is disposed on the upper side of the first linear portions which are located in a vicinity of the sensing module, wherein the planar portion is extended away from the sensing module along a length direction of the first linear portions, and formed to have a length substantially as long as the first linear portions; and
protrusions which are disposed on the planar portion and protrude in a same first direction as the tips, to fix the respective metal terminals to the fixing portion,
wherein each of the first linear portions of the metal terminals comprises an opening, and each respective protrusion is penetrated through a corresponding opening to fix the first linear portion of the respective metal terminal to the fixing portion.
2. The sensor with resin encapsulated terminal separation according to claim 1 , wherein:
a portion of a surface of the fixing portion, which is located in the vicinity of the sensing module, has a shape of a taper.
3. The sensor with resin encapsulated terminal separation according to claim 1 , wherein:
the sensing module is provided with a field generation portion that generates a field and a magnetic detection element that detects a variance of the field.
4. The sensor with resin encapsulated terminal separation according to claim 1 , wherein:
the sensor is employed as an in-vehicle device.
