Definitions
- the invention relates to the contact arrangement for plug connections, charging plugs for the transmission of electrical power, having at least one device for establishing an electrically conductive connection and at least one device for cooling, heat dissipation of the heat arising from the transmission of electrical power of the conductive connection, the invention also relates to plug connections, Charging plug with at least one such contact arrangement.
- Contacts in general have at least one electrically conductive contact section for detachable, temporary or plug-in connection with a corresponding mating contact element and a shaft section adjoining the contact section for fastening an electrical line to the contact.
- a contact, plug contact, high-current contact can be used on a charging plug or a charging socket, for example for charging an electrically powered vehicle.
- a cable is connected on the one hand to a charging station and on the other hand carries a connector part in the form of a charging plug, which can be plugged into an associated mating connector part in the form of a charging socket on a vehicle in order to establish an electrical connection between the charging station and the vehicle to manufacture.
- Charging currents can basically be transmitted as direct currents or as alternating currents, with charging currents and high-current areas in particular in the form of direct current having a high current strength, for example greater than 200 A or even greater than 300 A or even 350 A, and heating the cable, as well as a high-current contact connected to the cable.
- Such high-current contacts which are made of an electrically conductive material, for example from a copper material, heat up when a charging current flows through the contacts, plug-in contacts, high-current contacts, whereby the contacts are basically to be dimensioned depending on the charging current to be transmitted so that the Contacts have a sufficient current carrying capacity and heating at the contact elements is limited.
- the rule here is that the larger the charging current to be transmitted, the larger a contact must be.
- there are limits to scaling the contact element size with increasing charging current due to the associated space requirements, weight and costs. There is therefore a need to transmit a large charging current with a comparatively small-sized contact.
- a solution approach known in principle in the prior art is to passively or actively cool contacts, high-current contacts, in order to implement the transmission of electrical power with limited heating of the power-transmitting components even with smaller-sized components.
- DE 102016204895 A1 discloses a power contact system for a charging plug and / or a charging socket and a charging plug for coupling to a corresponding connecting device and for transmitting electrical energy.
- the object to be solved is to provide a charging plug by means of which increased charging currents can be transmitted without the charging plug heating up excessively.
- a power contact system for a charging plug and / or a charging socket has a power contact with a first connection area for galvanic connection with an electrical energy receiver and a second connection area for galvanic connection with a charging cable.
- a cooling element that is in direct contact with the second connection area of the power contact is provided, the cooling element having a cooling fluid inlet connection and a cooling fluid outlet connection fluidly connected to this by means of a cooling fluid channel arranged within the cooling element connected to the cooling element, which is designed in such a way that the cooling fluid is not in direct contact with the power contact.
- US 2015/0217654 A1 from Tesla Motors shows a charging system for an electric vehicle, comprising a power supply, a cable with a first and a second end, the first end being attached to the power supply, the cable comprising a charging wire and a cooling line, each of which extends from the first end to the second end; and a connector attached to the second end of the cable, the connector having a form factor that corresponds to a charging station of the electric vehicle; wherein the cooling line is suitable for transporting a fluid that cools the charging wire, line.
- the cooling line and the current-carrying charging wire are practically arranged as a line package.
- a charging cable known from DE 102010007 975 B4 with contacts, high-current contacts has a cooling line which comprises a feed line and a return line for a coolant and thus enables a coolant flow to and from the charging cable.
- the cooling line of DE 102010 007 975 B4 serves, on the one hand, to dissipate the heat loss that occurs in an energy store of a vehicle, but also to cool the cable itself.
- the charging cable is arranged concentrically within the cooling line and the cooling medium flows around it.
- EP 3043421 A1 shows an electrical connection body for a charging plug with a cooling device.
- An electrical connection body for a charging plug and / or a charging socket with a first connection area for galvanic connection with an electrical energy receiver and a second connection area for galvanic connection with an electrical energy source is presented and wherein the electrical connection body has a cooling fluid channel formed in the electrical connection body.
- High-current contacts are disadvantageous or in need of improvement in various respects.
- Often the cooling medium volume flows are not sufficient due to the reduced cross-sections of the supply and discharge lines to the cooling element.
- the volume of the cooling element is also undersized in many cases.
- the invention recognizes that, in addition to cooling the contact, high-current contact to increase the current to be transmitted while maintaining the same line cross-section, a direct connection of the conductor and cooling hose to the contact element, high-current contact, is suitable for achieving significant cooling improvements.
- the direct connection integratively supports both the conduction of electrical energy and the direct, improved one
- Cooling medium circulation, cooling medium volume flow or the failure of the cooling medium pump - can act as a buffer.
- the external cooling medium hose supports the increased cross-sectional area with an inlet and outlet hose arranged parallel to the electrical conductor, so that an increased cooling medium volume flow is possible.
- the invention provides that the current-carrying conductor, line, is located within the cooling tube.
- the conductor and the cooling hose are connected directly to the connecting element, contact carrier.
- the connecting element, contact carrier has at least one transverse bore through which the cooling medium can be introduced into a reservoir which forms the cooling element and can be discharged again.
- the invention is implemented by contact arrangements in plug connections in the context of charging systems for an electric vehicle, two contact arrangements, high-current contacts, are usually arranged in a charging plug.
- the invention provides two cooling medium hoses.
- a hose there is, for example, a direct current positive pole, in one of the direct current negative pole.
- a cooling medium hose is used as a supply line for cooling medium, and one is used as a return line. Both hoses can be fluidically coupled via the cooling element.
- the invention provides in a special way a cooling medium that is designed as an electrical insulator and thus an electrically non-conductive liquid is present. In this way, it is possible to directly couple the current-carrying and the cooling-medium-carrying components in an integrative manner, so that the cooling effect is supported as a result of the at least partially direct physical contact of the electrically conductive device and the cooling medium.
- a number of advantages are associated with the configuration according to the invention: Due to the current-carrying conductor, power supply line, located inside the cooling hose, it can be crimped to the contact, high-current contact in a simple and reliable manner using a conventional crimping process; the use of a braid that makes the connection difficult is not required
- Cooling medium hose is increased compared to individual hoses, so that an increased cooling medium volume flow can be achieved, the crimping area of the high-current contact, contact lies completely in the non-conductive cooling liquid, so that, as in the prior art, insulation does not make the heat transfer difficult, the elasticity and mobility of the flow and Cooling medium-conducting overall arrangement and compact design are supported, the heating of the device both during normal charging and in the event of a fault situation in the event of failure of the cooling medium volume flow is limited due to the structural design and dimensioning of a cooling medium reservoir.

- FIG. 1 a comprises a perspective view of the contact arrangement with a contact area 10 and a component of the cooling space delimitation 40, implemented by a cooling hose 41, coupled through and with a connection area 30.
- FIG. 1b shows a front view of the contact arrangement with connection area 30, formed by at least one connection element 31 with a contact receptacle 32, and in the lower illustration, the sectional top view C-C.
- connection region 30 essentially couples the at least one contacting 11 via the contact receptacle 32 to a hose receptacle 33 through the connection element, contact carrier 31, in a manner that is both electrically conductive and carrying a cooling medium.
- the receptacles 32, 33 of this exemplary embodiment are designed both in alignment and concentric to the central axis and are functionally supplemented by a receptacle 34 for the electrical conductor 20, likewise in an aligned and concentric manner.
- the connecting element 31 is preferably made of a material with electrical conductivity and heat conducting properties.
- the contact receptacle 32 and the line receptacle 34 in the connecting element 31 are designed as bores, holes, blind holes with or without internal threads that are introduced axially and at the end and can have an approximately 120 ° angle tip at the end - in the case of a blind hole design as a result of a drill bit.
- a through-hole with a constant diameter or a diameter that deviates from one another is also possible.
- the area of the contact receptacle 32 is preferably, but not necessarily, provided with an internal thread that is designed to be compatible with an adapter or the contact 11, such that the contact 11 can be fixed with or on the connecting element, contact carrier 31.
- the area of the line receptacle 34 is designed in such a way that a line 20 can be fixed.
- the coupling can take place by a press fit, by a crimping process or by clamping elements within the connecting element 31. Because of the particularly reliable connection properties of a crimped connection, this is a frequently preferred solution.
- One end side of the connecting element 31 is designed as a hose receptacle 33 for coupling a cooling hose 41.
- the hose receptacle 33 is formed by a cylindrical section onto which the hose 41 can be pushed axially.
- the hose 41 can be fixed, for example, by clamps, hose clamps or a press fit.
- the hose receptacle 33 can optionally be supplemented by a hose stop 35 in the form of a shoulder in the pushing-on direction and / or a bevel at the end, threading bevel 36.
- FIG. 2 illustrates a sectional front view A-A of a contact element with an outer cooling space delimitation 40, which is essentially formed by at least one cooling hose 41 and at least one cooling housing 42.

- a cooling housing adapter 43 can optionally be provided.
- the volume of the cooling reservoir 52 can be increased and / or adapted to the respective required cooling capacity without the contact arrangement having to be geometrically changed. This supports the use of identical parts for the contact arrangement even when different cooling capacities are required, so that different variants of the contact arrangement are not required. In this way, the production and its costs as well as storage and parts logistics can be implemented cost-effectively.
- the outer cooling space delimitation 40 can be sealed with or without a cooling housing adapter 43 by means of seals 44. O-rings with a preferably round cross-section, which are inserted into a corresponding groove with a groove depth smaller than the ring diameter, have proven particularly useful in rotationally symmetrical sealing surface situations.
- the outer cooling space delimitation 40 works functionally together with the inner cooling space delimitation, formed essentially by the line 20 and the connecting element 31.
- the geometric design of the invention results in a significantly improved heat transfer of the current-carrying components 20, 31 within the outer cooling space delimitation 40 due to the fact that the Cooling medium is in direct physical, physical contact. It is important that the invention provides for the use of a cooling medium that is designed as an electrical insulator and thus an electrically non-conductive liquid is present.
- the fluidic coupling is achieved by at least one cooling connection, opening 53, which connects both areas 51, 52 in such a way that a cooling medium volume flow or cooling medium exchange between the two areas is supported.
- the cooling medium movement between the line cooling area 51 and the connecting cooling area 52 can take place by means of a cooling medium volume flow through circulation as a result of temperature gradients within the medium or the components adjoining the medium and / or by means of an inlet and outlet combined with a cooling medium pump.
