Definitions
- the invention relates to a current sensor for a vehicle battery, a pole terminal for a vehicle battery and a vehicle battery with the current sensor and the pole terminal.
- an intelligent battery sensor IBS is called known. It is a current sensor, which is set up, a charge state of a vehicle battery based on the battery ⁇ voltage, battery current and temperature of the battery to determine.
- a current sensor includes for monitoring a vehicle battery, an electrical contact ⁇ element for establishing an electrical connection with one pole of the vehicle battery and a different formed by the electrical contact member mechanically holding member for holding the current sensor in at least one direction of the driving ⁇ generating battery.
- the specified, in particular designed as IBS current sensor is based on the consideration that a current sensor must be connected in series between an electrical energy source and a load, so that the current can be measured. Furthermore, the specified current sensor is based on the consideration that, in particular in high-current applications, such as in the field of vehicle technology, correspondingly massive cables are necessary for electrical connection of the electrical load to the electrical energy source. Due to the connection of the current sensor between the electrical load and the vehicle Series battery in series, however, there is the problem that the current sensor must carry the aforementioned cable.
- the specified current sensor attacks, in the context of which it is recognized that the electrical short circuit can be avoided if the series-connected current sensor not only conducts the electric current, but also takes over the mechanical hold of the cable to the vehicle battery.
- the electrical connection is usually mechanically too weak, so that the current sensor could be detached from the vehicle battery, if he alone has to take over the mechanical support.
- the mechanical holding element is therefore arranged as a type of reinforcing element on the current sensor, which ensures the mechanical hold of the current sensor, which now holds the cable, on the vehicle battery. If the current sensor is held by the mechanical holding element at the pole of the vehicle battery, then the cable need not be mechanically held in addition to the vehicle battery, so that can be dispensed with the aforementioned electrical insulation.
- the electrical contact element is arranged at a location of the current sensor which is outside of a holding action range of the mechanical holding element is located.
- the electrical contact element can be optimally adapted to its electrical contact effect by the separate formation of both elements, while the mechanical support member are optimally designed for its mechanical holding action can.
- a direction of an effect of the positive-locking element is dependent on a direction of force flow, into which a via the
- the holding element comprises at least one positive locking element for positive connection with the vehicle battery.
- the current sensor can be connected in a simple manner, for example, by hanging on the vehicle battery with this mechanically.
- a form fit is particularly easy to manufacture and can be designed exactly in the direction in which the mechanical support member must act in the manner previously explained in order to meet the increased mechanical stress applied by the cable.
- a terminal post for a vehicle battery comprising an electrical contact element for establishing an electrical connection to a connectable to the vehicle battery current sensor and a different formed by the electrical contact element mecha ⁇ African holding member for holding the current sensor in at least one direction on the vehicle battery.
- the electrical contact element is arranged at a position of the pole terminal ⁇ , which is outside a holding action range of me ⁇ chanical holding element.
- the holding element comprises at least one positive locking element for positive connection with the current sensor.
- a direction of action of the positive locking element from a direction of power flow is dependent, in which a connectable via the current sensor to the vehicle battery ⁇ cable acts on the terminal post.
- the positive-locking element is a stamped-bent element which can be attached to the specified pole terminal in a particularly cost-effective manner.
- a vehicle battery for delivering or receiving an electric current for a vehicle electrical system comprises one of the specified pole terminals for discharging or receiving the electric current and one of the specified current sensors, which is held on the pole terminal via the mechanical holding element and via the electrical contact element is electrically connected to the pole terminal.
- FIG. 1 is a diagram to illustrate the basic operation of a possible attachment of a cable to a vehicle battery via a current sensor.
- FIG. 2 shows a diagram for clarifying the basic mode of operation of an alternative attachment of a cable to a vehicle battery via a current sensor;
- FIG. 3 is an exploded perspective view of a pole terminal and a current sensor
- Fig. 4 is a perspective view of a pole terminal and a current sensor in an assembled state.
- the same technical elements are provided with the same reference numerals and described only once.
- FIG. 1 shows a diagram for clarifying the basic mode of operation of the attachment of a cable 2 to a vehicle battery 4 via a current sensor 6.
- the cable 2 can be fastened directly to the vehicle battery 4 for a stable hold.
- the current sensor 6 can via corresponding electrical and
- a mechanical holding element 12 for amplifying the mechanical hold of the current sensor 6 can be arranged on the current sensor 6 according to FIG. 2 at least in a pulling direction of the cable 2. Then the mechanical stop of the current sensor 6 on the vehicle battery 4 from, so that the direct mechanical connection of the cable 2 with the vehicle battery 4 and thus the insulation 10 are obsolete.
- the connection 14 between the current sensor 6 and the cable 2 can then be designed completely free.
- the current sensor 6 can, as shown by way of example in FIG. 3, have a housing 16 and an electrical cable connection 18 for connecting the cable 2.
- the housing 16 in the present embodiment may preferably be made of an electrically insulating plastic.
- a mold element 20 may be formed over the in a manner to be described, a positive connection with the vehicle battery 4 can be made.
- the current sensor 6 can also have an interface 22, via which measurement data can be sent to an evaluation device (not shown).
- the current sensor 6 can be connected in the present embodiment with a pole terminal 24, which can be attached, for example as part of the vehicle battery 4 in a conventional manner via a Feststellschraubtagen 25 to a not-shown but known per se pole of the vehicle battery 4.
- the pole terminal 24 has a soldering surface 26, on which the above-mentioned solder joint 8 can be realized.
- the pole terminal 24 has a hook 28, which can be produced in ⁇ example in stamping and bending technology.
- the current sensor 6 on the soldering surface 26 of the pole terminal 24 of the hook 28 can be bent against the mold member 20 so that the hook 28 forms a positive connection with the mold member 20 in a pulling direction 30 of the cable 6 and thus as the above-mentioned mechanical Holding element 12 is used.
- the mechanical support of the solder joint 8 on the soldering surface 26 is sufficient for holding the current sensor 6 at the pole terminal 24.
- the current sensor 6 connected to the pole terminal 24 is shown in FIG. 4 with the additionally connected cable 2.
