Definitions

  • the present invention relates to a battery current sensor for a motor vehicle, having a measuring sensor inserted into the battery circuit and having a housing connected to the measuring sensor and having a measuring circuit arrangement disposed within the housing.
  • Such a battery current sensor which is mechanically directly connected to a pole terminal of the battery, is known from DE 199 61 311 A1.
  • the problem is that the location of the battery and the
  • the measuring sensor has electrical connection means at its end portions, wherein at least one of the connecting means is connected via a positionable connecting means with the measuring sensor.
  • the measuring sensor can be adapted in a simple and cost-effective manner to different cable outlet directions and to the respective space conditions at the place of installation of the battery.
  • the position-variable connections between the measuring sensor and the electrical connection means can be carried out in an advantageous manner by pivot joints, preferably by ball joints. It is particularly advantageous if these position-variable connections are mechanically fixed after the electrical connection by squeezing, clamping or crimping.
  • the measuring sensor itself can be advantageously formed by a simple metal strip.
  • a measuring device connected to the metal strip evaluates a dependent on the flow of current through the metal strip physical quantity, such as resulting from the current flow magnetic field or heating.
  • a particularly simple and proven method of current measurement is to regard a portion of the metal strip as a measuring resistor, and to detect the voltage dropping there.
  • the portion of the metal strip used for the measurement may advantageously be provided with a plastic surround forming a part of a housing comprising the actual measuring circuit.
  • a part of a connector can also be formed on this housing via which the measuring circuit of the battery current sensor can be connected to other vehicle components.
  • FIG. 1 is a sectional view of a first battery current sensor
  • FIG. 2 shows a plan view of the battery current sensor shown in FIG. 1,
  • FIG. 1 shows a sectional view of a battery current sensor constructed according to the invention.
  • the battery current sensor consists of a simple metal strip (1a), which has in its middle region a plastic encapsulation (3), which forms part of a housing (2).

Since the connecting means (5, 6) are connected via ball joints with the measuring sensor (1), the positioning of the connecting means (5, 6) relative to the measuring sensor (1) can be adapted very flexibly to the respective vehicle-specific circumstances. In addition, if necessary, vehicle-specific adapted connection means can be provided without structural changes to the measuring sensor (1) would have to be made. This makes a particularly simple and cost-effective adaptation of the battery current sensor to different vehicles possible.
