Description

  • The invention relates to an electrical connection element for the electrical connection of two electrical components according to the preamble of the independent claim.
  • From the prior art, a plurality of electrical connection elements for connecting two electrical components are known. In this case, a first component is usually designed as a plug, which is inserted into a corresponding insertion opening of the second electrical component. In electric vehicles, the electrical contacting of a battery or an electric drive machine brings with it corresponding challenges, in particular if the electric drive machine is oil-cooled. In particular, such electrical connecting elements for high-voltage connections are known from the prior art, which connect two each dry-running electrical components. In this case, the electrical contact is particularly simple, since only for a corresponding power transmission in the interior of the electrical connection element and an electrical insulation must be ensured to the outside. Furthermore, from the prior art sealed interfaces are known which require a relatively large amount of space. In addition, it is difficult to integrate a corresponding sensor for measuring current in a sealed interface. Furthermore, the degree of sealing is sometimes low, so that the sealed interfaces only allow a seal against spray oil, but not against an oil sump. In addition, some sealed interfaces are not suitable for the direct mounting of power electronics.
  • From the DE 10 2016 216 933 A1 a plug for electrically contacting an electric motor is known, wherein the plug has a housing with a fastening means provided with the first boom and a further attachment means provided with second boom for attachment to a stator and a positioning means for positioning the plug on the stator. Furthermore, a temperature sensor for determining a temperature of the electric motor is provided.
  • The WO 2004/020814 A1 discloses a wire harness for the electrical connection of an injector to an engine control unit of an internal combustion engine. In this case, the injector is arranged in a cylinder head of the internal combustion engine and lapped by coolant or lubricant. In this case, the cable harness comprises a first portion and a second portion which are interconnected via a clamping support and a hood, wherein both the clamping support and the hood have means for self-locking.
  • In addition, from the WO 2006/077208 A1 a control module for a motor vehicle transmission known. The control module has a first housing part, on which a first circuit part is arranged. The control module further has a second housing part and a carrier, on which a flexible conductor foil is arranged. The conductor foil is connected to the circuit part in a housing interior located between the first and the second housing part. The conductor foil is further electrically connected outside of the housing interior with electrical components fixed to the carrier. In this case, a stack-shaped structure is provided, in which the carrier is arranged with a first side on a provided with the circuit part inside of the first housing part, the circuit part is arranged in a recess of the carrier, the flexible conductor foil on the side remote from the first housing part second Side of the carrier is arranged and the second housing part is placed on the flexible conductor foil.
  • The invention is now based on the object to propose an electrical connection element for the electrical connection of two electrical components, which overcomes the disadvantages known from the prior art and is inexpensive to manufacture and easy to assemble.
  • According to the invention, this object is achieved by an electrical connection element for electrically connecting a first electrical component to a second electrical component, wherein the first electrical component has a housing bush in which a first busbar is guided. In this case, it is provided that the housing bush has, on its end face facing the housing of the first electrical component, a first sealing element, with which the housing bushing is sealed off from the housing. It is further provided that the housing bushing is covered on its end face facing away from the housing by a cover, wherein between the cover and the housing bush, a second sealing element is arranged, with which the first busbar relative to the housing bush and the lid is sealed. In this case, the second sealing element is preferably designed as a circumferential seal made of an elastomer, which is received in a form-fitting manner in a groove on the end face of the housing bush facing away from the housing. By means of this sealing combination it is achieved that the housing bush is sealed in a liquid-tight manner with respect to the housing even when the plug is not plugged in, and thus leakage of a liquid coolant for the first electrical component is reliably prevented. In this case, the seal opposite to known from the prior art electrical interfaces increased Sealing degree, so that the housing socket is also suitable for use in an oil bath.
  • By the features listed in the dependent claims, advantageous improvements and developments of the electrical connection element specified in the independent claim are possible.
  • In a preferred embodiment of the invention, it is provided that the electrical connection element comprises a plug with a plug housing in which a second bus bar is arranged, wherein the second bus bar can be inserted into at least one plug opening of the housing socket. As a result, a highly integrated and extremely compact design of the electrical connection element is possible.
  • In a further preferred embodiment of the invention, it is provided that the plug housing has a fifth sealing element, in particular a peripheral seal, on its end face facing the housing of the first electrical component. As a result, an additional sealing of the plug-in area relative to the environment is possible, so that entry of dirt or liquid from the plug side is reliably prevented.

Preferably, a further screw connection for mounting the socket in the housing of the first electrical component is provided. As a result, the tightness of the first electrical components is ensured even without a mounted connector housing. By a screw connection, a cost-effective and easy-to-install solution of the electrical connection element is possible. In this case, no additional sockets or other components must be mounted in the assembly, so that can save installation time and thus assembly costs.
  • For many applications, it is advantageous if a measuring unit for current measurement is arranged on the second busbar. By means of a measuring unit for measuring the current at the second busbar, it is possible to provide the required control processes with the current actual value and thus to enable effective current regulation. In this case, an arrangement on the second busbar of the plug with respect to an arrangement on the first busbar in the housing socket is advantageous because the second busbar is more accessible in the connector housing and a current anyway flows only when the first busbar and the second busbar are in contact ,
  • It is particularly preferred if the measuring unit is designed as a Hall sensor or as a measuring resistor. Hall sensors and measuring resistors are simple and cost-effective sensors for determining the current at the second busbar. In this case, both a Hall sensor and a measuring resistor, which is also referred to as a shunt, can be integrated to save space in the connector housing of the plug.

By a vertical arrangement a particularly simple joining and connecting between the plug and the housing socket is possible. In particular, the risk of bending the busbars in the assembly is reduced.
  • It is particularly preferred if in the region of the contact zone, a pressing element, in particular a spring tongue, is provided, with which the portion of the second busbar is pressed against the portion of the first busbar. By a pressing the contact area between the first busbar and the second busbar is biased, whereby a higher security against lifting of one of the busbars and thereby impaired power transmission is given. Further, a latching mechanism may be provided on the clamping element in order to ensure a fully inserted plug tongue of the second bus bar locking the plug in this position.
  • In a further preferred embodiment of the electrical connection element it is provided that a plurality of mutually parallel busbars are provided on the housing bushing and on the plug. By several mutually parallel busbars additional functions can be realized. When using an electrical connecting element according to the invention in an alternating current, the different conductors can be realized by the different busbars. Furthermore, larger currents can be transmitted via a plurality of busbars, which are preferably arranged parallel to one another. Alternatively or additionally, it is possible that further information is transmitted via the corresponding busbars, so that project-related a suitable number of busbars and plug-in openings can be selected.
  • Particularly advantageous is an embodiment of the electrical connecting element, in which the first electrical component is lubricated by a liquid medium and the second electrical component is kept free of contact with a liquid medium. Due to the high sealing effect, the electrical connecting element according to the invention is particularly advantageous when an electrical component of liquid, in particular by an oil bath, is surrounded, in particular to cool this electrical component, and the second electrical component must be kept dry urgently.
  • In a preferred embodiment of the invention it is provided that the first electrical component is an electric drive motor of a motor vehicle and the second electrical component is a power electronics or a wiring harness of a motor vehicle. A preferred application for an inventive electrical connection element is the electrical interface between a preferably oil-cooled electric drive machine in a motor vehicle on the one hand and a power electronics or a wiring harness on the other side. In this case, a functionally reliable electrical connection can be realized by the electrical connection element.
