Embodiment Construction

[0019] FIG. 1 shows a battery current sensor designed according to the invention in a sectional view. The battery current sensor has a measuring sensor 1 with a measuring resistor 1 a formed by a metal strip, which has a plastic encapsulation 3 in its central region, which forms part of the housing 2 . The housing 2 has a housing cover 9 as a further housing part, which has a plastic encapsulation 3 , preferably connected by laser welding, and which has a molded plug cage as part of the plug connector 4 .

[0020] Measuring resistor 1 a has a simple cylindrical shaped part 11 on its end section, and connecting elements 5 , 6 are arranged rotatably about their central axis. After the relative position of the connecting elements 5 , 6 is fixed relative to the measuring sensor, their position is locked by co-pressing of the connecting points.

[0021] As shown in FIG. 2 , the first electrical connection element 5 is designed as a battery pole terminal 8 with a ring-shaped termin...

In the sensor, at least components of the measurement circuit device are arranged on a circuit substrate. , the circuit substrate is electrically and mechanically connected to the measuring sensor in a positionally fixed manner via connecting elements, wherein each connecting element has at least one press-in contact via which the connecting element is connected to the circuit substrate and / or to the measuring sensor. connected.

Description

technical field [0001] The invention relates to a battery current sensor for automobiles, comprising a measurement sensor embedded in a battery circuit and a measurement circuit device connected to the measurement sensor, in which at least parts of the measurement circuit device are arranged on a circuit substrate , the circuit substrate is electrically and mechanically connected to the measuring sensor in a positionally fixed manner via the connector. Background technique [0002] A battery current sensor of this type is known from DE 199 61 311 A1, which is mechanically arranged directly on the pole terminals of the battery. In the battery current sensor described therein, the measuring sensor is designed to measure electrical resistance and is connected to the printed circuit board via a soldered connection. The contact surfaces of the measuring sensor are here made of copper, while the resistance itself is made of manganese-nickel-copper alloy, so that the measuring sen...
