摘要:
A sensor device has a sensor element, two connecting elements configured as a wire and are led out of the sensor element, and a supporting element having a supporting body and two supporting feet to support the temperature sensor in a housing. The two connecting elements, the sensor element and the supporting body bound between themselves a two-dimensional clearance of a predefined width and height. A minimum dimension of the sensor element and the length and height of the supporting feet are dimensioned, relative to the clearance, such that neither the sensor element nor one of the supporting feet can enter the clearance of an adjacent sensor device.

A sensor for detecting the angular position of a rotary drive shaft is disclosed which includes a stator, a rotor connected to the stator by a ball joint and including a moving target, and a drive shaft connected to the rotor. The moving target passes through a detection system and produces a signal as a function of its position. Variations in the sensor output signal due to misalignment of the rotor and the drive shaft are minimized by locating the moving target close to the axis of rotation of the ball joint.

An in-line skate wheel assembly for a skate mounted speedometer or odometer that includes a signal processor and display housing mounted on the skate toe with a sensor mounted under the toe very close to the forward wheel. A field producing sensing element is fixed in the elastomeric portion of the forward wheel where it passes in close proximity to the sensor as the wheel rotates. The display housing is connected to the sensor by a flat conductor and the three are quickly removable as a unit from the skate.

The encapsulated transducer (10) includes an injection molded encapsulation (20) having a front end (22) and a back end (24). The encapsulation (20) ensconces a sensing element (40) proximate the front end (22) and a portion of a cable (60) which extends from the back end (24). The sensing element or coil (40) is electrically and mechanically connected to the cable (60) by a pair of suitably sized front and rear ferrules (80), (90) secured to a center and coaxial conductor (66), (70) of the associated cable (60) thereby forming a coil and cable assembly (110). At least the rear ferrule (90) includes a shoulder (100) for firmly anchoring the coil and cable assembly (110) within the encapsulation (20). In addition an injection molding process provides the durable encapsulation (20) which bonds with a dielectric (68) of the cable (60) and symmetrically locks the coil and cable assembly (110) therein.

In a traverse device mounting type or handy type fluid measuring probe in which a plurality of conductive lines are connected to a contact type sensor element and the conductive lines are covered by a support member, or a test member attachment type fluid measuring probe, a fluid measuring probe is provided in which when the probe head or the support member is brought into contact with other things, an impact force is moderated and a damage of the probe head and the support member is suppressed. When a pressure that is not less than a predetermined pressure is applied to the support member in a direction perpendicular to a longitudinal direction of the support member, the support member may be bent; when the pressure is released, the support member may be restored; and when the pressure that is not less than the predetermined pressure is not applied, the support member may maintain a predetermined posture.

An integrated circuit sensor assembly (10) is mounted to a solid surface (11) of a metal leadframe (12) by placing RTV adhesive (30-36) at the four corners of the substrate (14). The RTV material cover less than the entire surface area between the leadframe surface and the substrate. The RTV provides coplanar support for the sensor assembly while maintaining a gap between a significant portion of the surface area between the substrate and the leadframe surface. The metal leadframe undergoes compression and expansion stresses from temperature cycling during the manufacturing process. The gap decouples the sensor assembly from leadframe and provides stress isolation. Moreover, the flexibility and resiliency of the four corner RTV dots absorb stress induced by the leadframe.

An apparatus for packaging a vehicle sensor and integrated circuit chip includes a ceramic substrate having an opening formed therein. A sensor is secured within the opening. An integrated circuit chip is secured within the opening in electrical communication with the sensor. A pair of electrical connectors are secured on the ceramic substrate in electrical communication with the integrated circuit chip. A metal lid is secured over the opening on the ceramic housing to enclose the integrated circuit chip and sensor. A molded plastic coating encloses the ceramic housing and metal lid, and the electrical connectors extend from the plastic coating. The sensor may be a pressure sensor or acceleration sensor.
