Definitions

  • the invention relates to a battery current sensor for a motor vehicle, with a measuring resistor inserted into the battery circuit.
  • a battery current sensor which is arranged mechanically directly on a pole terminal of the battery, is known from DE 199 61 311 A1.
  • the measuring sensor is designed as a measuring resistor and connected via solder connections to a printed circuit board.
  • the contact surfaces of the measuring sensor are made of copper, while the actual measuring resistor consists of manganin;
  • the measuring sensor thus formed should be the same
  • the non-prepublished German patent application DE 10 2004 053 650 shows a battery current sensor with a strip-shaped measuring resistor which has integrally formed cylindrical end sections.
  • the cylindrical end portions are used for power supply in or Stromabtechnisch from the measuring resistor, and are contacted by connecting means designed as a pivot joints.
  • a middle, strip-shaped region with a small cross-section relative to the end sections forms the resistance region of the measuring sensor.
  • the task arose to provide a battery sensor with a particularly simple and inexpensive measuring resistor, which can be easily coupled to the environment.
  • the measuring resistor comprises a core of a first material having a uniform cross section and two sleeves connected to the core of a second material, wherein the second material is lower resistance than the first material.
  • the resistance region thus consists of a first material with a constant cross-section over its length, which can be square, rectangular and preferably round, for example.
  • This can be dispensed with a complex shape of the resistance region in this measuring resistor; instead, this section can be made by simply cutting a rod-shaped blank from the resistor material.
  • this resistance area with two particularly good conductive sleeves made of a low-resistance material is firmly connected. Due to the solid connection, which can be produced by crimping in an advantageous manner, contact resistance between the sleeves and the core are avoided.
  • this plastic injection molding can advantageously form part of a sensor housing which, for example, has a housing
  • FIG. 1 shows a pre-assembled measuring resistor
  • FIG. 2 shows a sectional view of the measuring resistor
  • FIG. 3 shows a final mounted measuring resistor
  • Figure 4 shows an alternative embodiment of a measuring resistor in one
  • Sectional view, Figure 5 shows a battery sensor with a measuring resistor.
  • FIG. 1 shows the assembled but not yet finally mounted elements of a measuring resistor (1) for a battery sensor of a motor vehicle.
  • the measuring resistor (1) has a cylindrical core (4) made of a resistance material, preferably manganin.
  • On the end portions of the core (4) are sleeve-shaped connecting elements, hereinafter referred to briefly as sleeves (5), postponed. Since the sleeves (5) form the terminal regions of the measuring resistor (1), they are made of a material which conducts as well as possible, preferably made of copper, in order to minimize the contact resistances to be attached to the connecting means.
  • the core (4) forms the resistance region of the measuring resistor (1) and is therefore made of a material which, compared to the Sleeve material, specifically higher resistance.
  • the core (4) consists of manganin.
  • the core (4) has in its longitudinal direction a uniform cross section, ie a cross section with a constant shape and dimension. This results in advantages that the core (4) forms a simple compact component, which is easy to manufacture and also distributes occurring in a motor vehicle, sometimes quite high battery currents to a relatively large cross-section.
  • the core (4) instead of a circular cross-sectional area also have an oval, square, rectangular or other polygonal cross-sectional shape.
  • FIG. 2 shows in a sectional view the sleeves (5) plugged onto the end sections of the core (4).
  • a preferred way to do this is to press the sleeves (5) and the core (4) under high mechanical pressure with each other.
  • This process also referred to as crimping, causes the peripheral surfaces (6) of the sleeves (5) to be acted upon in sections with a very high force, as a result of which the sleeves (5) are compressed in the radial direction and compressed inseparably with the core material.
  • a good electrical coupling to the core (4) is thereby simultaneously achieved.
  • FIG. 3 shows, the shape of the sections (6) acted on can change in this production step as a result of the action of force.
  • Previously circular sections (6) of the sleeves (5) have, for example, a hexagonal shape after the crimping operation.
  • the recesses (8) in the sleeves (5) are made slightly smaller in diameter than the diameter of the core (4). Only after a strong heating of the sleeves (5), due to the associated thermal expansion, the core (4) in the sleeve recesses (8) can be used. After cooling the sleeves (5) a solid connection to the core (4) is made.
  • the electrical connection of the measuring resistor with the vehicle battery or with the consumers of the vehicle electrical system can be carried out in an advantageous manner via connecting elements, as described in DE 10 2004 053 650.
  • the connecting elements shown therein are first mounted rotatably on the end portions of the sleeves, whereby their mechanical position can be aligned according to the course of the conductor guide of the electrical system. If this is done, the connecting elements, preferably also by crimping, mechanically fixed to the sleeves.
  • FIG. 5 shows a completely constructed battery current sensor in a sectional view.
  • the battery current sensor has a measuring resistor (1), which consists of a core (4) and the associated sleeves (5).
  • the measuring resistor (1) is provided with a plastic extrusion (3) which forms part of a housing (2).
  • the housing (2) has as a further housing part a housing cover (9), which is connected to the plastic extrusion (3), preferably by means of a laser welding.
  • the sleeves (5) advantageously have projections (11), such as along the circumference grooves, which produce a positive connection with the plastic extrusion (3) and thereby secure the position of the housing (2) relative to the measuring resistor (1).
  • a measuring circuit arrangement on a circuit substrate (10), which may be designed in particular as a printed circuit board or ceramic substrate constructed.
  • the measuring circuit receives the evaluation signal to be evaluated via connecting means (7), which are electrically connected both to the circuit carrier (10) and with the sleeves (5) of the measuring resistor (1).
