Definitions
- the invention relates to a charging connector for electric and hybrid vehicles, with a housing, DC charging contacts arranged in the housing for contacting corresponding DC charging contacts of a corresponding DC charging connector and AC charging contacts arranged in the housing for contacting corresponding AC charging contacts of a corresponding AC charging connector.
- Electric and hybrid vehicles have a rechargeable energy storage device, usually a high-voltage battery, which provides energy to an electric drive motor during ferry operation.
- the storage capacities of these high-voltage batteries are limited, so they have to be recharged regularly at a charging station.
- the battery is charged via a charging cable provided between the charging station and the vehicle, whereby the charging cable can be used, for example.
- B. in accordance with the European standard IEC 62196 Type 2, on one side with a charging plug that can be plugged into a charging socket provided at the charging station, and on the other side with a charging coupling that can be connected to a charging plug installed in the electric and hybrid vehicle .
- charging sockets, charging plugs, charging couplings and charging connectors are subsumed under the term “charging connectors”.
- Charging sockets and charging couplings have contact sleeves as charging contacts and charging plugs as well as charging connectors that can be installed in electric and hybrid vehicles have contact pins as charging contacts that can be inserted into the contact sleeves.
- the task is to be solved to provide an electrical connection body which enables increased charging currents with limited heating and therefore has an increased short-term current carrying capacity.
- This task is to be solved by providing an electrical connection body for a charging plug or a charging socket, wherein the electrical connection body has a first connection region for galvanic connection to an electrical energy receiver and a second connection region for galvanic connection to an electrical energy source, wherein the electrical connection body is designed such that it has a cooling fluid channel formed in the electrical connection body, wherein the cooling fluid channel of the Electrical connection body is fluidly connected to a cooling fluid source, which is arranged in a charging station.
- Cooling of a charging connector for electric and hybrid vehicles, which originates from the side of the charging station, is also otherwise well known from the prior art.
- DE 10 2015 119 338 Al describes that two connection points for coolant lines are arranged on a contact sleeve element of a charging plug. By means of a spiral-shaped plug-on element, coolant is guided circularly around the contact sleeve element. The two connection points serve as inlet and outlet for the coolant, which is routed from the charging station to the charging connector.
- EP 3 433 902 B1 also describes a connector part with cooled contact elements.
- a coolant is provided via coolant lines to the contact elements of the charging socket connected to the charging cable.
- a fluid is provided as a coolant, which is directed into the hollowed-out contact element perpendicular to the contact element and flows back within the contact element.
- 10 2016 105 361 B4 also describes a connector part with a cooled contact element, with the charging station side also providing a coolant via coolant lines to the contact elements of a charging socket connected to the charging cable.
- Guide elements are arranged on the contact elements and are intended to allow the coolant in the form of compressed air to flow around the contact elements.

- the installation of the heat-conducting element therefore improves the possibility of dissipating heat generated on or in the DC charging contact towards the AC charging contact.
- the heat absorbed at the AC charging contacts is then on the vehicle side, for example. B. can be transferred into the electrical lines of the AC contacts, which absorb the waste heat and allow it to be released into the body into the environment through the increased surface area of the lines all the way to the vehicle's battery.
