Definitions

  • the invention relates to a connector part for connection to a mating connector part according to the preamble of claim 1.
  • Such a connector part comprises at least one contact element for electrical contacting with an associated mating contact element of the mating connector part and a contact holder on which the at least one contact element is held.
  • one or more contact elements can be held in a housing of the connector part, for example, and be stationarily positioned so that the contact elements form a mating face on a plug-in section of the connector part.
  • the contact holder with the contact elements arranged thereon forms an assembly which can be attached in preassembled manner to the housing of the connector part, so that facilitates the assembly of the contact elements in the housing.
  • Such a connector part can be used, in particular, as a charging plug or as a charging socket for charging an electrically driven vehicle (also referred to as an electric vehicle).
  • a cable is connected on the one hand to a charging station and on the other hand carries the 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 Produce vehicle.
  • Charging currents can be transmitted in principle as direct currents or as alternating currents, in particular charging currents in the form of direct current a large current, for example greater than 200 A or even greater than 300 A or even 350 A, and to a heating of the cable as well as one with the Cable connected connector part can lead.
  • a charging cable known from DE 10 2010 007 975 B4 has a coolant line which comprises a supply line and a return line for a coolant and thus allows a coolant flow to and fro in the charging cable.
  • the coolant line of DE 10 2010 007 975 B4 serves on the one hand for discharging at one Energy storage of a vehicle resulting heat loss, but also for cooling the cable itself.
  • a charging system for charging an electric vehicle heat is generated not only on the cable to which a charging plug is connected for example to a charging station, but also on the charging plug and in particular within the charging plug, for example on contact elements, via which an electrical contact with associated mating contact elements, for example Side of a charging socket on an electric vehicle is made when the charging plug is plugged into the charging socket.
  • Such contact elements which are made of an electrically conductive metal material, such as a copper material, heat up when a charging current flows through the contact elements, in principle, the contact elements are to be dimensioned in dependence on the charging current to be transmitted so that the contact elements sufficient Have current carrying capacity and heating at the contact elements is limited. The rule here is that a contact element is to be dimensioned and designed so that the required currents can be safely transmitted.
  • a scaling of the contact element size with increasing charging current are limited due to the associated space requirements, the weight and the cost. There is therefore a need to transfer a large charging current with a comparatively small sized contact element.
  • coolant lines are routed within a charging cable, via which heat can also be removed from the region of a connector part connected to the charging cable.
  • cooling ribs are arranged on a shaft of the contact element.
  • the object of the present invention is to provide a connector part with a contact element which can have a high current carrying capacity, for example for use in a charging system for charging an electric vehicle.
  • the contact holder has a base body and an insulating jacket of an electrically insulating material that at least partially encloses the base body, wherein the base body has at least one channel for flowing through with a coolant.
  • the contact holder on the one hand serves to hold and position one or more contact elements, for example in a housing of the connector part.
  • two contact elements in the form of so-called load contacts for transmitting a direct current can be held on the contact holder.
  • An additional contact element may form a so-called PE contact for contacting with a neutral.
  • Other contact elements may be provided which serve as signal contacts for transmitting control signals.
  • the contact holder also serves for cooling, in particular, those contact elements which, during operation, conduct large currents and which can consequently result in heating during operation.
  • At least one channel is formed in the base body of the contact holder, which can be flowed through with a coolant, for example a liquid coolant (for example water) or a gaseous coolant (for example air), so that heat is absorbed by the base body and the base body can be removed.
  • a coolant for example a liquid coolant (for example water) or a gaseous coolant (for example air), so that heat is absorbed by the base body and the base body can be removed.
  • the main body is preferably formed of a good thermal conductivity material.
  • the base body may be made of a metal material, for example aluminum, for example as an aluminum die-cast part. Heat can thus be conducted away from the contact elements arranged thereon via the base body and transferred to the coolant flowing through the channel, so that heat can be removed from the contact holder via the coolant.
  • the main body forms, for example, one or more attachment points to which one or more contact elements can be mechanically fixed.
  • the base body for example, made of metal, in this case has a sufficient mechanical stability, so that the contact elements are held firmly and reliably on the structure created by the body structure on the contact holder.
  • the base body is wrapped in particular in the region of its attachment points through the insulating, so covered that the contact elements not directly electrically conductive abut the body, but the contact elements on the insulating against the Body are electrically isolated.
  • these load contacts are in each case electrically insulated from the main body via the insulating jacket, so that the contact elements are not short-circuited to one another via the main body.
  • the insulating sheath at least partially envelops the base body, is to be understood in the present case that the insulating sheath is arranged at least partially on the base body and the base body at least partially covered such that the main body is insulated.
  • the wrapping does not have to be complete.
  • the insulating jacket does not necessarily have to provide an overlap on an outer side of the main body, but can also be arranged, for example, on an attachment point for a contact element forming bore or the like.
  • an attachment point for attaching a contact element to the base body may be formed by a bore in the base body.
  • the insulating jacket covers the base body, e.g.
  • the insulating jacket thus serves as an insulating layer between the contact element inserted into the bore and the base body.
  • the channel extends helically around an associated fastening point.
  • the channel is in this case formed in the base body and allows, through its course around the attachment point, to absorb heat in the base body where it arises. Due to the helical course of the channel around the attachment point, heat can be absorbed directly via the coolant flowing through the channel to a contact element attached to the attachment point and can be effectively transported away from the contact element.
  • load contacts are to be electrically insulated from the base body made of metal, a contact element which serves to connect a neutral conductor, preferably contacted with the main body electrically. This so-called PE contact is thus directly attached to an attachment point formed on the main body, without the insulating jacket electrically isolating the PE contact from the main body.
  • the insulating jacket is preferably made of an electrically insulating plastic, for example PVC or PA66.
  • the base body to form the insulating jacket may be at least partially encapsulated in plastic, so that the base body is at least partially covered by the insulating jacket and thus a region-wise electrical insulation of the body is provided.
  • the insulating jacket is preferably made of a plastic, which is advantageously thermally conductive and can provide a high dielectric strength.
  • a plastic material providing a dielectric strength in a range between 10 kV / mm and 15 kV / mm may be used. This makes it possible, with a wall thickness of, for example, a few tenths of a millimeter to achieve sufficient insulation of the load contacts forming contact elements relative to the base body.
  • the insulating jacket can also have a mechanically supporting function.
  • the insulating jacket in the region of an attachment point for fastening a contact element, can form an insertion bush, into which the at least one contact element with a shaft section to be connected to a load line is inserted.
  • the shaft portion can thus protrude into the insertion.
  • the load line is crimped for electrical contacting, for example, wherein the crimping can be accommodated within the insertion.
  • the main body forms a channel, which is flowed through by a coolant during operation, so that heat is absorbed by the main body and by the main body can be derived.
  • the main body can have, for example, two connections via which a coolant can be introduced on the one hand into the channel and on the other hand out of the channel. Via coolant lines connected to the connections, a coolant circuit is thus provided by the base body, via which heat can be removed from the connector part.
  • the coolant lines are preferably laid in a cable connected to the connector part, in which one or more load lines for electrical energization of the contact elements of the connector part are added.
  • a gaseous fluid can flow into the channel via the one port and is discharged from the channel elsewhere without being returned via a coolant line.
  • the main body with the channel formed therein may be made for example by selective laser sintering.
  • Selective laser sintering is understood to mean a generative production method in which spatial structures are produced by sintering with a laser from a powdery starting material (preferably a metal material).
  • the workpiece is built up layer by layer, so that a fundamentally arbitrary three-dimensional geometry, in particular with a molded-in channel, can be created by the action of the laser beams.
  • a connector part of the type described here can be used, for example, as a charging plug or charging socket in the context of a charging system for charging an electric vehicle.

  • the channel 358 is integrally molded into the body 35 and, in separate channel sections 358A, 358B, helically extends around the attachment locations 350 and insert bushings 361 formed therein by the insulating jacket 36 so that coolant around the attachment locations 350 and insert bushings 361 formed therein can flow around to absorb heat at the attachment points 350 and attached thereto contact elements 32 and to be able to dissipate from the attachment points 350.
  • the channel 358 formed inside the main body 35 has a port 352 which serves for the supply of coolant in a flow direction F1 (see FIGS. 18 and 19). From the connection 352, the channel 358 branches to form two separate channel sections 358A, 358B, which are each associated with an attachment point 350. Each channel section 358A, 358B has its own port 353, which serves as a drain for discharging the coolant in a flow direction F2. As shown schematically, for example, in FIG. 17, flow lines 21, 22, which are routed inside the charging cable 2 and are supplied and removed via the coolant, are connected to the connections 352, 353.
  • the main body 35 in the embodiment according to FIGS. 11 to 19 is produced for example by a selective laser sintering method.
  • selective laser sintering which is a generative manufacturing process
  • the base body 35 is fabricated layer by layer with the channel 358 formed therein from a (metal) powder material.
  • a (metal) powder material Basically, with the selective laser sintering complex three-dimensional structures can be formed.
  • a plurality of different flow channels can be formed in the main body of the contact holder so that a coolant can flow through the main body along different flow paths.
  • a coolant can flow through the main body along different flow paths.
