Abstract:
An inductive non-contact rotation angle sensor used in a motor-driven throttle valve unit is such that a circuit substrate to which a stationary conductor and an electronic circuit are attached is secured to a resin cover without the use of an adhesive. A TPS substrate as the circuit substrate and an electric conductor are electrically connected to each other by pressure welding (press fit). The circuit substrate and the electric conductor can be formed of the same molding resin as a single molded body. Thus, it is not necessary to prepare another metallic conductor (a bonding wire) and also welding and soldering are eliminated. Further, since the TPS substrate is covered by the same material as cover resin, a process of bonding the substrate to the cover can be omitted, which allows for a reduction in manufacturing cost.
