Description

FIELD OF THE INVENTION

[0001] The present invention relates to the field of automobiles. More specifically, the present invention relates to an electrical connector for electrically connecting two or more components for a motor vehicle. Furthermore, the present invention relates to a corresponding motor vehicle. BACKGROUND INFORMATION

[0002] In the event of an accident involving the motor vehicle, it may be necessary that emergency responders disconnect the components electrically, especially if the components are high voltage components. Disconnecting high voltage allows for safer handling of a distressed battery electric vehicle by emergency responders. Electrical disconnection of the components may particularly increase safety for passengers and emergency responders. From the state of the art, actuator devices are known, but these typically are not manual and may require replacement after having been used. Furthermore, fuses and switches are known from the state of the art. However, fuses cannot be controlled advantageously, because they may react to voltage spikes. Therefore, it can be difficult for rescue teams to disconnect the two or more components by using actuator devices or fuses. Switches may be turned on and off to break an electrical circuit, however, switches may become deformed, in particular in case of an accident of the motor vehicle, and may be subject to larger errors. Furthermore, it is conceivable to disconnect the two or more components by cutting a cable. However, this may have drawbacks, such as involving considerable effort for the emergency responders and safety aspects, in particular in the event that the emergency responders make a mistake when cutting the cable. SUMMARY OF THE INVENTION

[0003] It is an object of the present invention to provide an electrical connector for electrically connecting two or more components for a motor vehicle as well as a corresponding motor vehicle, by which in case of an accident of the motor vehicle safety of the motor vehicle can be particularly increased.

[0004] This object is solved by an electrical connector for electrically connecting two or more components for a motor vehicle, as well as a corresponding motor vehicle according to the independent claims. Advantageous embodiments are presented in the dependent claims.

[0005] One aspect of the invention relates to an electrical connector for electrically connecting at least two components for a motor vehicle. Preferably, the motor vehicle is designed as a passenger car. Preferably, the motor vehicle is a battery electric vehicle (BEV) or a hybrid vehicle, in particular a plug-in hybrid vehicle (PHEV). The said components may be referred to as electrical, respectively electronic components. Preferably, the components are high voltage components.

[0006] The electrical connector comprises at least one conductor. Moreover, the electrical connector comprises at least one first coupling interface for electrically connecting the conductor to a first of the said components. The first coupling interface may be understood as a first coupling section or a first coupling location respectively. Furthermore, the electrical connector comprises at least one second coupling interface for electrically connecting the conductor to the second of the said components. The second coupling interface may be understood as a second coupling section or a second coupling location, respectively.

[0007] The electrical connector comprises at least an insulation surrounding the conductor, in particular at least partially or completely. In other words, the insulation encloses the conductor. The insulation may be understood as a housing of the electrical connector, in particular covering the conductor. The housing may be referred to as a casing.

[0008] The conductor comprises a first predetermined breaking point, via which at least a portion of the conductor is electrically connected to the first coupling interface, and in particular to the first of the said components. The first predetermined breaking point may be understood as a first breaking section or a first breaking location, respectively. Moreover, the conductor comprises a second predetermined breaking point, via which at least the said portion of the conductor is electrically connected to the second coupling interface, and in particular to the second component. The second breaking point may be understood as a second breaking section or a second breaking location of the conductor, respectively.

[0009] In particular, to increase safety of the motor vehicle, in particular safety of passengers and / or emergency responders, in the event of an accident of the motor vehicle, the electrical connector comprises at least one handling region at least partially, in particular completely, surrounding the said portion of the conductor. The handling region is provided on the insulation. Via which handling region a force can be applied manually to the conductor in order to break the conductor at the predetermined breaking points for the purpose of disconnecting the electrical connection between the two said components. In other words, the electrical connector, in particular the said portion of the electrical connector, is designed as a breakaway cable, which may break at the predetermined breaking points, if the said manually applied force is greater than a, in particular predetermined, threshold. So the electrical connector may be understood as a breakaway cable for electrically connecting the two said components and for manually disconnecting the two said components. The said disconnecting of the two components or of the electrical connection between the two components, respectively, may be understood as an interrupting of the electrical connection between the said two components.

[0010] The use of the electrical connector or the breakaway cable, respectively, would allow for disconnecting of high voltage in a quick and safe fashion. The breakaway cable, in particular the said portion of the conductor, may be pulled manually from vehicle and interrupt an electrical flow, in particular high voltage flow, between the two said components. Therefore, the electrical conductor, in particular the said portion of the conductor, is designed as a manually removeable cable. The removal of the cable would decrease a chance of an electrical shock or an electrical fire. In particular, the breakaway cable or the electrical connector, respectively, is an enclosed electrical connector which serves the emergency function of deenergizing the motor vehicle, which is preferably designed as a BEV.

[0011] The breakaway cable or disconnecting the two said components by the electrical connector, respectively, is a manual operation, preferably not using an actuator or other fuse type functions. In contrast, a fuse is an automatic operation based on a thermal limit of the conductor being surpassed. The breakaway cable is a manual operation based on direct physical action of an operator or rescuers. In particular, the said electrical connector differs from an emergency shut off switch on industrial equipment, due to the power not being subject to immediate reset. Furthermore, the electrical connector may be used to avoid an alternative high voltage disconnecting procedure, which requires cutting a high voltage cable, in particular inside the passenger compartment. This may improve the safety of the motor vehicle.

[0012] According to an embodiment the conductor comprises a second conductor portion which adjoins the said portion of the conductor at one end and protrudes obliquely or perpendicularly from the said portion of the conductor, which may be referred to as first portion of the conductor. The conductor comprises a third conductor portion which adjoins the said first portion at the other end and protrudes obliquely or perpendicularly from the said first portion of the conductor.

[0013] In another embodiment the first predetermined breaking point is at least partially, in particular completely, formed by the second conductor portion and the second predetermined breaking point is at least partially, in particular completely, formed by the third conductor portion.

[0014] In another embodiment the handling region is provided on a first insulation portion. Preferably, the insulation comprises a second insulation portion protruding obliquely or perpendicularly from the first insulation portion. The insulation comprises a third insulation portion protruding obliquely or perpendicularly from the first insulation portion. Preferably, the second insulation portion is connected to the first insulation portion via a first predetermined breaking point of the insulation and the third insulation portion is connected to the first insulation portion via a second predetermined breaking point of the insulation. Preferably, upon application of the manually applied force to the handling region, the first insulation portion is capable of being released from the second insulation portion at the first predetermined breaking point of the insulation and is capable of being from the third insulation portion at the second predetermined breaking point of the insulation for the purpose of covering the at least said portion of the conductor.

[0015] In another embodiment the second insulation portion at least partially surrounds the second conductor portion, and the third insulation portion at least partially surrounds the third conductor portion.

[0016] In another embodiment after breaking the conductor at the predetermined breaking points, the first coupling interface is insulated by the second insulation portion and the second coupling interface is insulated by the third insulation portion.

[0017] In another embodiment after breaking the conductor at the predetermined breaking points, at least a part of the second conductor portion, which is still electrically connected to the first coupling interface, is insulated by the second insulation portion, and at least a part of the third conductor portion, which is still electrically connected to the second coupling interface, is insulated by the third insulation portion.

[0018] In another embodiment the handling region is designed as a handle to be grabbed by a person.

[0019] Another aspect of the invention relates to a motor vehicle comprising an electrical connector according to the first aspect of the invention. Advantageous embodiments of the motor vehicle are to be regarded as advantageous embodiments of the electrical connector and vice versa.

[0026] In the present document, the word "exemplary" is used herein to mean "serving as an example, instance, or illustration". Any embodiment or implementation of the present subject matter described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure.

[0028] The terms “comprises”, “comprising”, or any other variations thereof, are intended to cover a non-exclusive inclusion so that a setup, device or method that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or device or method.

[0029] In the following detailed description of the embodiment of the disclosure, reference is made to the accompanying drawing that forms part hereof, and in which is shown by way of illustration a specific embodiment in which the disclosure may be practiced. This embodiment is described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.

[0030] Fig. 1 shows a schematic view according to an embodiment of a motor vehicle 10. The motor vehicle 10 is preferably at least in part electrically operated or full electrically operated. Therefore, the motor vehicle 10 may comprise an electric motor. Furthermore, the motor vehicle 10 may comprise a battery, which is preferably designed as a high voltage component. For example, the motor is supplied with energy by the battery.

[0031] The motor vehicle 10 comprises at least one electrical connector 12 for electrically connecting two components 14, 16 of the motor vehicle 10. For example, one of the said components 14 is the electric motor and another of the two said components 16 is for example the battery. So the conductor 18 is preferably designed as a conductive path for electrically connecting the components 14, 16.

[0032] Fig. 2 shows the electrical connector 12 in a schematic sectional view. The electrical connector 12 comprises at least one conductor 18. Preferably, the conductor 18 is formed from metal. For example, the electrical connector 12, in particular the conductor 18, has a metal conductive core, cable, or solid bar.

[0033] The electrical connector 12 comprises at least one first coupling interface 20 for electrically connecting the conductor 18 to a first of the said components 14. Furthermore, the electrical connector 12 comprises at least one second coupling interface 22 for electrically connecting the conductor 18 to the second of the said components 16. For example, the conductor 18 terminates on both ends with a termination jack going into a main system power socket of the motor vehicle 10.

[0034] In addition, the electrical connector 12 comprises at least one insulation 24 surrounding the conductor at least partially. For example, the insulation 24 is an external structure of the cable.

[0035] The conductor 18 comprises at least a first predetermined breaking point 26 and at least a second predetermined breaking point 28. Via the first breaking point 26 a portion 29 of the conductor 18 is electrically connected to the first coupling interface 20. The said portion 29 of the conductor 18 may also be referred to as first conductor portion 29. Via the second breaking point 28 at least the first conductor portion 29 is electrically connected to the second coupling interface 22.

[0036] In order to improve safety of the motor vehicle 10, in particular safety of passengers and / or emergency responders, the electrical connector 12 comprises at least one handling region 30 at least partially surrounding the first conductor portion 29, which is provided on the insulation 24. Via which handling region 30 at least one force can be applied manually, for example by an emergency responder, to the conductor 18 in order to break the conductor 18 at the predetermined breaking points 26, 28 for the purpose of disconnecting the electrical connection between the two said components 14, 16. This means that the electrical connector 12, in particular at least the first conductor portion 29, acts like a, in particular manual, breakaway cable, preferably high voltage breakaway cable. So at least one conductive element of this breakaway cable serves an emergency safety function of deenergizing the motor vehicle 10 for emergency responders. It is therefore possible to break a high voltage circuit in order to reduce the risk for rescuers, vehicle occupants, and the surrounding environment. Furthermore, due to the electrical connector 12 comprising the breaking points 26, 28 there is no need of cutting a cable, in particular a high voltage cable, connecting the two said components 14, 16. Therefore the electrical disconnection of the two components 14, 16 may be safe, easy and / or fast. Especially there are no cutting action risks and no ark, spark, flash and / or shock hazards involved. A reconnection of a cut cable can also be avoided. Furthermore, there are no ragged cable ends that may cut skin or snag clothing. In addition, there is no cutting tool needed that may create a conductive path to the motor vehicle 10. It may also be avoided that a cutting tool may become snagged in distressed vehicle deformities. Moreover, a responder's dexterity may be affected by heavy gloves, breathing apparatus and / or radio equipment. By the electrical connector 12 the two components 14, 16 may be disconnected easily and quickly, in particular despite the heavy gloves, the breathing apparatus and / or the radio equipment.

[0037] In an embodiment the conductor 18 comprises a second conductor portion 32 which adjoins the said first conductor portion 29 at one end and projects obliquely or perpendicularly from the said first conductor portion 29. Preferably, the conductor 18 comprises a third conductor portion 34 which adjoins the said first conductor portion 29 at the other end and projects obliquely or perpendicularly from the said first conductor portion 29. So at least the conductor 18, in particular the complete electrical connector 12, is designed in a horseshoe pattern. Thus, the conductor 18 can break securely and purposefully at the breaking points 26, 28 in order to disconnect the two said components 14, 16.

[0038] In order to break the conductor 18 purposefully and securely at the breaking points 26, 28, the first predetermined breaking point 26 is for example at least partially formed by the second conductor portion 32 and the second predetermined breaking point 28 is for example at least partially formed by the third conductor portion 34.

[0039] In another embodiment the insulation 24 has different portions 36, 38, 40. The handling region 30 is provided on a first insulation portion 36 of the said portions 36, 38, 40. A second insulation portion 38 of the said portions 36, 38, 40 protrudes obliquely or perpendicularly from the first insulation portion 36. A third insulation portion 40 of the said portions 36, 38, 40 protrudes obliquely or perpendicularly from the first insulation portion 36. So for example the electrical connector 12 comprises two fasteners, wherein the first conductor portion 29 and / or the first insulation portion 36 are attached to the fasteners. For example, a first of the two said fasteners comprises the second conductor portion 32 and / or the second insulation portion 38. The second fastener for example comprises the third conductor portion 34 and / or the third insulation portion 40. The fasteners are preferably designed as non-conductive fasteners. So the breakaway cable, in particular the first conductor portion 29, is for example designed as a small removable segment of a cable held in place by the two non-conductive fasteners. The two non-conductive fasteners provide complete and safe insulation during normal operations. For example, the non-conductive fasteners may be removed by hand, in particular there are no tools needed. The removal of the non-conductive fasteners and the breakaway cable could be done by hand or with a non-conductive pole.

[0040] So the conductor 18 is preferably encased in insulated material to allow safe daily operations and clean removal without cracks, fractures, and / or deterioration of insulated material. For example, the insulation 24 is designed as a reinforced tube. So the conductor 18, which is for example designed as a cable, may run through a reinforced tube, in particular inside the encasement. This provides an overall structure and prevents hands or tools from touching the conductor 18.

[0041] In another embodiment the insulation 24 comprises two predetermined breaking points 42, 44 that preferably are different from the breaking points 26, 28 of the conductor 18, for example at different locations. For example, the second insulation portion 38 is connected to the first insulation portion 36 via a first predetermined breaking point 42 of the said breaking points 42, 44 of the insulation 24. For example, the third insulation portion 40 is connected to the first insulation portion 36 via a second predetermined breaking point 44 of the said breaking points 42, 44 of the insulation 24. In order to break the conductor 18 securely, upon application of the force to the handling region 30, the first insulation portion 36 is capable of being released from the second insulation portion 38 at the first predetermined breaking point 42 of the insulation 24 and the first insulation portion 36 is capable of being released from the third insulation portion 40 at the second predetermined breaking point 44 of the insulation 24 for the purpose of covering at least the first conductor portion 29.

[0042] In order to cover the conductor 18 securely, in another embodiment the second insulation portion 38 at least partially surrounds the second conductor portion 32 and the third insulation portion 40 at least partially surrounds the third conductor portion 34.

[0043] In order to cover the conductor 18 securely, in another embodiment after breaking the conductor 18 at the predetermined breaking points 26, 28, the first coupling interface 20 is insulated by the second insulation portion 38 and the second coupling interface 22 is insulated by the third insulation portion 40.

[0044] Alternatively or additionally, after breaking the conductor 18 at the predetermined breaking points 26, 28, for example at least a part of the second conductor portion 32 which is still electrically connected to the first coupling interface 20, in particular to the first component 14, is insulated by the second insulation portion 38 and at least a part of the third conductor portion 34 which is still electrically connected to the second coupling interface 22, in particular to the second component 16, is insulated by the third insulation portion 40.

[0045] In another embodiment the handling region 30 is designed as a handle 46 to be grabbed by a person. Thereby the disconnection of the two components 14, 18 can be manually executed easily and quickly. For example, the handling region 30 is configured like a suitcase handle, in particular with a guitar cable inside. An exterior material of the handling region 30 is preferably designed in such a way that it does not chip, shred and / or crack. Preferably the material of the handling region 30 allows for good grip to be established.

[0046] For example, the electrical connector 12 is arranged in the motor vehicle 10 in a secured location that is protected against accidental deformation. This means that the electrical connector 12 may occur in a position that is not subject to influence of vehicle deformity. In other words, connections of the electrical connector 12 are for example made in a secure area, in the fashion of a black box on an airplane, meaning the breakaway cable is not able to be damaged or distorted. The electrical connector 12 is for example arranged in a passenger compartment of the motor vehicle 10. In the event of an accident of the motor vehicle 10 the access to the high voltage cable may require the driver and rescuers to posture clear of each other. The rescuer may be inside of the damaged vehicle which may shift position. Due to the secured location of the electrical connector 12 the electrical connector 12, in particular the handling region 30, is accessible for the rescuer. Alternatively or additionally cable terminations and / or a travel path of the electrical connector 12 may be attached inside of a reinforced structure, in particular a box structure.

[0047] The operation of the electrical connector 12 is illustrated in Fig. 2, in particular by the arrow 48, which illustrates a direction of a manual removal operation, for example carried out by the rescuer.

[0048] In another embodiment the electrical connector 12, in particular the insulation 24, comprises at least one indication area 50 for indicating that at least the first conductor portion 29 is disconnected completely from the coupling interfaces 20, 22, in particular disconnected from the two components 14, 16. For example, each of the two fasteners, in particular each of the two insulating portions 38, 40, comprise such an indication area 50. This indication area 50 is for example designed as a colored band. So the cable or at least the first conductor portion 29, respectively, may either be removed fully from the motor vehicle 10 or the electrical connector 12, in particular the conductor 18 and / or the insulation 24, have some reflective color bands to indicate the cable or the first conductor portion 29, respectively, has disconnected successfully, for example from the main system power of the motor vehicle 10. For example, the color of the indication area 50, in particular a red color, indicates that the cable or at least the first conductor portion 29, respectively, has moved far enough to disconnect from the main system power. The distance of this movement should be equal on both sides.

[0049] The breakaway cable preferably has enough space to be entirely removed, for example from under a dashboard. For example, the retained breakaway cable or the retained first conductor portion 29, respectively, has an orientation assuming exterior impact pushing inwards onto the motor vehicle 10. For example, a cable extraction path should not complicate removal of passengers from the distressed motor vehicle 10. For example, the operation of the electrical connector 12 presumes that the distressed vehicle occupant is having minimal strength and dexterity. For example, the operation of the electrical connector 12 presumes that the rescuer is operating from outside a closed door. For example, an interior material of the electrical connector 12 should not complicate the travel path. Soft interior material does not break and snag rescue implements. For example, there are no moving parts unlike a switch or a button to kill power, meaning there is greater structural integrity.

[0050] It is also possible to use a fuse block style of removable circuit interruption. A standardized location of the electrical connector 12 in the motor vehicle 10 may speed response times.

[0051] For example, the electrical connector 12 is designed as an anti-theft deterrent. This means that the removal of the cable or the removal of the first conductor portion 29 may also be used as an anti-theft deterrent. Once removed, a factory and / or a dealership reset may be required to assure safe, reliable operations.
