In a connection arrangement between a sensor and connection leads, only a small installation space is required. To this end, the connection arrangement has a signal amplifier, which is electrically contacted by means of bond connections with the sensor and the connection leads. This is achieved by means of connecting elements, which are designed as thin sheet-metal shaped parts and are fixed with tab-shaped end sections in a housing of plastic, in which the signal amplifier is also inserted. The end sections, the signal amplifier, and the bond connections are arranged in a space-saving manner in roughly one plane. The connection arrangement is especially suited for sensors used to measure the speed of motor vehicles.
A system for performing an electronic control in open or closed loop, in particular of functions of a motor vehicle, including at least one electronic control unit and at least one actuator and/or sensor assigned to the control unit, the at least one actuator and/or sensor being controllable via a control unit-actuator/sensor interface, in which variant-determining circuit elements which are arranged outside of the control unit, in particular driver modules are provided between the respective interfaces and the actuator and/or sensor.
The invention relates to a device for detecting the movement of a movable component, the device having an inner part 1 and the inner part 1 having a housing in which are mounted conductors 3 that carry electrical components 4 and a sensor element. One end of each conductor 3 protrudes from the inner part 1 forming plug contacts 6, and the inner part 1 is encapsulated by a plastic housing 2 in such a way that the plug contacts 6 project into a plug receiver 5 in the plastic housing. The electrical components 4 and the sensor element are covered by covers and encapsulated by the plastic housing 2. The covers protect the components from the plastic in the encapsulation process.
A rotation sensor includes a rotation detector mounted on a holder which is in turn inserted in a casing through its opening. A cover is formed by molding a resin so as to cover the opening of the casing and the portion of the holder protruding from the opening of the casing. A pair of relay terminals extend through a base portion of the holder and a gap defined in the holder, are fixed to a support wall, and connected to respective lead pieces of the detector. A resin cover is formed by molding a resin. When forming the cover, pressure is applied to the holder, thereby causing the holder to bulge axially in the holder. This in turn pushes the relay terminals in the axial direction. But since the relay terminals are fixed to the support wall, the support wall will absorb such pushing force, thereby preventing such pushing from being transmitted to the detector. In order to more effectively absorb such pushing force, the relay terminals may be provided with bent portions in the gap.
