Description
ELECTRICAL DIAGNOSIS DEVICE FOR AN AUTOMOTIVE VEHICLE
TECHNICAL FIELD
The present invention relates to an electrical diagnosis device, preferably arranged to electrically diagnose an electrical system of an automotive vehicle engine compartment.
BACKGROUND OF THE INVENTION
The number of sensors and actuators in an automotive vehicle engine compartment has increased a lot in particular since the stage 3 of the European emission standards. These sensors and actuators have to be regularly tested to check their functioning throughout the lifetime of the vehicle. However, they are less and less accessible due to packaging constraints in the engine compartment of the vehicle. Additionally, their dimensions are chosen as small as possible to reduce the size of the engine in the vehicle, making them even more difficult to access to. Furthermore, their connecting pins are so small that they can be damaged when connecting them to measurement devices, like oscilloscopes or multimeters.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to resolve the above mentioned problems in providing a wiring harness for an in-situ electrical diagnosis of an automotive electrical system, comprising electrical cables linking a female connector and a male connector, each of said female and male connectors being arranged to be plugged into a respective element of the system, an intermediate connector through which the female connector and the male connector are electrically connected, said intermediate connector comprising at least one plug and being arranged to derive and measure an electrical signal passing through said cables between the female and male connectors such that said automotive electrical system can be diagnosed without being entirely disassembled.
Thanks to the claimed device, it is possible for the measurement device to be connected to the electrical system to be analyzed, even when the electrical system is hard to access, as is often the case for electrical compounds in a vehicle engine compartment Each of said female and male connectors may be arranged to be plugged into an electrical connector or into a wire of an automotive vehicle.
Each of the female connector and the male connector may comprise a plurality of pins, each pin of the female connector being connected to a respective pin of the male connector through a respective electrical point of the intermediate 10 connector.
The intermediate connector may comprise a plurality of plugs, each plug being a stem.
The intermediate connector may comprise a plurality of plugs, each plug being held by a wafer or a box.
At least one of the female connector and male connector may have neutral coding The present invention also concerns a method for in-situ electrically diagnose an automotive electrical system, comprising the following steps: opening the electrical system by disconnecting two elements of said electrical system, plugging the female connector and the male connector of the wiring harness as already described into each of said disconnected elements of the electrical system, and connecting at least one plug of the intermediate connector to a measurement device so as to electrically diagnose the electrical system The electrical system may be disposed inside an automotive vehicle, the disconnected elements of the electrical system being an electrical connector and a wire.
The electrical system may be a sensor or an actuator of a combustion engine electrical control unit.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention is now described by way of example with reference to the accompanying drawings in which: Figure 1 is a perspective view of an electrical diagnosis device as per the invention in use.
Figure 2 is a perspective view of the electrical diagnosis device according a first embodiment of the invention Figure 3 is an electrical scheme of the device of figure 2 Figure 4 is a perspective view of the electrical diagnosis device according a second embodiment of the invention Figure 5 is an electrical scheme of the device of figure 4.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
As can be seen from the figures, the invention relates to an electrical diagnosis harness or device 1 for an electrical system. The device is particularly arranged to be used for an electrical system disposed inside an automotive vehicle, more specifically for a sensor or an actuator of an engine control.
For instance, the sensor can detect pressure, like air, water, diesel pressure. Or, the sensor can detect temperature, like air, water or diesel or any other fluid temperature. Or, the sensor can detect position, like a position of a camshaft or a crank shaft or a shutter.
For instance, the actuator can be an electromagnetic control of a piston of an injector, a solenoid, an electromagnet.
As can be seen from the figures, the electrical diagnosis device 1 comprises a first, female connector 2 and a second, male connector 3, each of said female and male connectors being arranged to be plugged into a respective element of the system.
The respective elements of the system may be a connector or a wire.
As shown in figure 1, the female connector 2 is plugged into a connector 4 linked to an injector 5 while the male connector 3 is plugged into a wire 6.
The device 1 &so comprises an intermediate connector 7 through which the female connector 2 and the male connector 3 are electrically connected.
As can be seen from figures 3 and 5, each of the female connector 2 and the male connector 3 comprises a plurality of pins. Each pin 11 of the female connector 2 is connected to a respective pin 12 of the male connector 2 through a respective electrical point 13 of the intermediate connector 7.
The intermediate connector 7 is provided with at least one plug 8. In the illustrated embodiments, the intermediate connector 7 comprises a plurality of plugs 8 that are in the form of stems or banana plugs 9 for the first embodiment (see figure 2) and held by a box 10 for the second embodiment (see figure 4).
The plugs 8 are arranged to be connected to a measurement device, like an oscilloscope 14, a multimeter 15 or a voltmeter, or a clamp ammeter 16, as shown in figure 1.
It should also be noted that the female and male connectors 2, 3 have neutral coding so as to be adapted to any variant of any vehicle connector. In other words, the female and male connectors 2, 3 have no poka yoke element.
In use, a method for electrically diagnose an electrical system according to the present invention comprises the following steps: - disconnecting the two respective elements of the electrical system, - plugging the female connector 2 and the male connector 3 into each of said disconnected elements of the electrical system, and - connecting at least one plug 8 of the intermediate connector 7 to one of the measurement devices so as to electrically diagnose the electrical system.
Therefore, thanks to electrical diagnosis device 1 and its use, it is possible to test any kind of sensor or actuator, whatever their location in the vehicle or size.
The invention has been described for a vehicle sensor or actuator. Obviously, the invention is not limited to such an application.
