Description
Wiring Harness Des cript ion I0 The invention relates to a wiring harness for an electric device, such as an electric motor and/or controller.
Electric motors and motor controllers that are sealed and submerged in oil are facing oil temperature variation that causes air pressure variation in the motor and controller bodies. Along the time, this can result in oil intrusion in the motor and controller bodies.
This can be solved by creating a separated vent conduit between the electric motor or the controller of the electric motor and the ambient air.
It is a disadvantage of such kind of a separated vent conduit that it requires additional holes in the motor and controller body as well as in the oil containing case.
It is the object of the invention to provide ventilation for an electric device, such as an electric motor and/or a controller that avoids additional holes in the motor body, in the controller body and in the oil containing case.
The solution of the object is achieved by the features of claim 1. Preferred embodiments are given by the dependent claims.
One subject of the present invention is a wiring harness, in particular for electric connection and ventilation of an electric device, such as an electric motor and/or a controller, for example an electric motor and/or a controller of an automatic transmission system, comprising a bundle comprising one or more electric conductors having a first and a second end. The wiring harness is characterized in that the bundle further comprises at least one gas conduit for conveying a gas, such as air, having a first and a second end.
By this means, the gas conduit in the electric wiring harness can be used for ventilation (aeration) of an electric device, such as an electric motor and/or a controller, which is submerged in oil. Advantageously, connection points, which are already used for electric connection, can be thereby used. In that way, additional holes in the motor body, in the controller body and in the oil containing case can be avoided. This in turn reduces part proliferation, cost and assembly time.
The bundle can for example comprise two or more electric conductors. In particular, the bundle can comprise a plurality of electric conductors. The electric conductors are preferably covered with an electric insulator.
The gas conduit may be a tube, in particular a flexible tube.
In a preferred embodiment of the wiring harness, the gas conduits are formed of a polyamide, for example Polyamide 11. Polyamides, in particular Polyarnide 11, have advantageously a high thermal resistance.
In a further preferred embodiment of the wiring harness, the wiring harness further comprises at least one first combined electric and gas-pass-through connector, whereby the first end of at least one electric conductor and the first end of at least one gas conduit are connected to the first combined electric and gas-pass-through connector. For example, thereby each first end of the electric conductors and each first end of the gas conduits can be connected to the first combined electric and gas-pass-through connector. By this means, a separated gas conduit connector can be avoided, which advantageously facilitates the mounting and reduces the risk of oil intrusion.
In a further preferred embodiment of the wiring harness, the wiring harness comprises at both ends a first and a second combined electric and gas-pass-through connector, respectively. Thereby, the first end of at least one electric conductor and the first end of at least one gas conduit are connected to the first combined electric and gas-pass-through connector and the second end of the at least one electric conductor and the second end of the at least one gas conduit are connected to the second combined electric and gas-pass-through connector.
By this means, the mounting can advantageously even more eased.
The combined electric and gas-pass-through connector can for example comprise: at one side, at least one electric conductor connection and at least one gas conduit mounting and at the other side, at least one electric plug or plug socket connected to the at least one electric conductor connection for connecting an electric conductor of the wiring harness to a corresponding plug socket or plug of a corresponding combined electric and gas-pass-through connector, for example of an electric motor and/or a controller, and at least one, for example male-type or female-type, gas conduit coupling connected to the at least one gas conduit mounting for connecting a gas conduit of the wiring harness to a corresponding, for example female-type or male-type, gas conduit coupling of a corresponding combined electric and gas-pass-through connector, for example of an electric motor and/or a controller.
In a further preferred embodiment of the wiring harness, the wiring harness further comprises a casing tube, whereby the bundle is arranged in the casing tube.
The bundle can in particular extend from one end to the other end of the casing tube. The casing tube may be flexible or inflexible casing tube.
In one embodiment the casing tube is an open casing tube. By this means, the mounting of the wiring harness can be even more be eased.
In another embodiment the casing tube is a sealed casing tube. Thereby, the bundle can additionally be protected against the environment, for example against heat and oil.
In Particular, the wiring harness can be a wiring harness for an electric motor of an electric (auxiliary) pump, in particular of an automatic transmission system, such as an 8-speed automatic transmission system.
Another subject of the present invention is an electric motor, for example an electric motor that is used submerged in oil, such as an electric motor of an automatic transmission system, comprising a connector, which is characterized in that the connector is a combined electric and gas-pass-through connector for electric connection and ventilation of the electric motor.
In a preferred embodiment of the electric motor, the electric motor further comprises an electric motor controller.
In a further preferred embodiment of the electric motor the combined electric and gas-pass-through connector of the electric motor is constructed for electric connection and ventilation of the electric motor and the electric motor controller. The combined electric and gas-pass-through connector can thereby be a part of an electric motor unit of the electric motor and/or be connected to an electric motor unit of the electric motor and/or be a part of the motor controller and/or be connected to the motor controller.
In Particular, the electric motor can be an electric motor of an electric (auxiliary) pump, in particular of an automatic transmission system, such as an 8-speed automatic transmission system.
A further subject of the invention is a ventilated electric motor system, for example for an automatic transmission system, comprising a wiring harness, an electric motor and a vent and which is characterized in that the wiring harness is a wiring harness according to the invention. Thereby the first end of at least one electric conductor and the first end of at least one gas conduit of the wiring harness can be connected to the electric motor. The second end of the at least one gas conduit of the wiring harness can thereby be the vent or can be connected to the vent. The second end of the at least one electric conductor can thereby also be connected to the vent.
In a preferred embodiment of the ventilated electric motor system, the ventilated electric motor system comprises a wiring harness having a first electric and gas-pass-trough connector according to the invention and an electric motor having a combined electric and gas-pass-through connector according to the invention.
Thereby the first combined electric and gas-pass-through connector of the wiring harness can be connected to the combined electric and gas-pass-through connector of the electric motor. Thereby for ventilation of the electrical motor, the second end of the at least one gas conduit of the wiring harness can be the vent or can be connected to the vent. The vent can thereby either be a simple opening or a mechanically ventilated opening. By this, gas can be conveyed from the vent to the electric motor by the gas conduction of the wiring harness.
For electric connection of the electric motor, the second end of the at least one electric conduit of the wiring harness can thereby also be connected to the vent.
Thereby, electric energy can be conveyed from the vent to the electric motor by the electric conductor of the wiring harness.
In particular, the system can comprises a wiring harness, having a first and a second electric and gas-pass-trough connector according to the invention.
Thereby, the first combined electric and gas-pass-through connector of the wiring harness can be connected to the combined electric and gas-pass-through connector of the electric motor, whereby the second combined electric and gas-pass-through connector of the wiring harness can be connected to a combined electric and gas-pass-through connector of the vent.
Yet another subject of the invention is the use of a wiring harness according to the invention for electric connection and ventilation of an electric device, such as an electric motor and/or a controller, for example to be used submerged in oil, such as an electric motor of an electric (auxiliary) pump and/or a controller of an electric motor of an electric (auxiliary) pump, in particular of an automatic transmission system, such as an 8-speed automatic transmission system.
These and other aspects of the invention will be apparent from and elucidated with reference to a preferred embodiment described hereinafter.

Figure 1 shows a schematic view of one embodiment of a ventilated electric motor system 10,50,60 according to the invention. Figure 1 illustrates that comprises a wiring harness 10, an electric motor 50 and a vent 60.
The wiring harness 10, comprising a bundle 12,14 of a plurality of electric conductors 12 and one gas conduit 14. Figure 1 illustrates that the wiring harness 10 further comprises at both ends a first 16 and a second 18 combined electric and gas-pass-through connector, respectively. Thereby the first end of the electric conductors 12 and the first end of the gas conduit 14 are connected to the first combined electric and gas-pass-through connector 16 and the second ends of the electric conductors 12 and the second end of the gas conduit 14 are connected to the second combined electric and gas-pass-through connector 18.
Moreover, Figure 1 shows that the wiring harness 10 comprise a casing tube 20, whereby the bundle 12,14 is arranged in the casing tube 20, so that it extends from one end to the other end of the casing tube 20. For clarity reasons, Figure 1 shows an open casing tube.
However, in the context of the present invention a sealed casing tube 20 is preferred for protecting the electric conductors 12 and gas conduits 14 against environmental effects.
Further on, Figure 1 illustrates that the wiring harness comprises fixing elements 22, which are attached to the casing tube 20. Moreover, Figure 1 shows that the bundle 12,14 of the wiring harness 10 can be split, so that a part of the electric conductors 12 and optionally gas conduits 14 (not illustrated) can be connected to device 70 different from the electric motor 50 and vent 60.

For ventilation of the electrical motor 20, the second end of the gas conduit 14 of the wiring harness 10 is connected to the vent 60. Thereby gas can be conveyed from the vent 60 to the electric motor 50 by the gas conduit 14 of the wiring harness 10. The vent 60 can either be a simple opening or a mechanically ventilated opening.
Figure 2 shows a cross-sectional view in section B-B of the second combined electric and gas-pass-through connector 18 of the ventilated electric motor system 10,50,60 shown in Figure 1. Figure 2 shows that the second combined electric and gas-pass-through connector 18 is mounted in a wall 24 of an oil containing case, so -10 - that one side of the second combined electric and gas-pass-through connector 18 contacts the oil 26 in the oil containing case, whereas the other side of the second combined electric and gas-pass-through connector 18 contacts air 28. The wiring harness 10 and the electric motor 50 are thereby arranged in the oil containing case and therefore submerged in oil 26.
Figure 2 shows that the second combined electric and gas-pass-through connector 18 comprises at the oil contact side a plurality of electric conductor connections 30 and one gas conduit mounting 32. At the air contact side, the second combined electric and gas-pass-through connector 18 comprises a plurality of electric plugs/pins 34, which are connected to the electric conductor connections 30, respectively, for connecting an electric conductor 12 of the wiring harness to a corresponding plug socket of a corresponding combined electric and gas-pass-through connector.

Figure 3 shows a cross-sectional view in section C-C of the first combined electric and gas-pass-through connector 16 and the electric motor 50 of the ventilated electric motor system 10, 50, 60 shown in Figure 1. Figure 3 shows that the first combined electric and gas-pass- -11 -through connector 16 comprises at one side a plurality of electric conductor connections 38 and one gas conduit mounting 40. At the other side, the first combined electric and gas-pass-through connector 16 comprises a plurality of electric plugs/pins 42, which are connected to the electric conductor connections 38, respectively, for connecting an electric conductor 12 of the wiring harness 10 to a corresponding plug socket of the corresponding combined electric and gas-pass-through connector 56 of the electric motor controller 52.
