Definitions
- the invention relates to a connector part for mechanical and electrical connection to a mating connector part, in particular a motor vehicle charging socket for coupling to a charging plug as part of an electrical charging infrastructure for electric or hybrid motor vehicles, or vice versa, with a housing made of plastic and at least one arranged in the housing electrical contact element, and with a heat transport element which is in thermal contact with the electrical contact element.
- the connector part is generally a charging socket in a motor vehicle, which can be coupled to an associated charging plug that is present, for example, on an electric charging station.
- the charging plug (like the charging socket) is part of an electrical charging infrastructure that can be used to charge the rechargeable energy storage devices or accumulators of electric or hybrid motor vehicles.
- the connector part on the motor vehicle can also be a charging plug instead of a charging socket.
- the charging station is equipped with an associated charging socket.
- the electric or hybrid motor vehicle has a charging socket with several electrical contact elements arranged in the housing, into which the charging plug connected to the charging station is inserted for charging the motor vehicle in question.
- a connector part including a temperature monitoring device is described in the prior art according to EP 3 616 270 B1. If the contact element overheats, the temperature monitoring device ensures that the power is switched off or at least the current is reduced.
- the procedure is such that the contact element is equipped with a heat capacity element or a heat transport element. This is intended to optimize and accelerate the heat dissipation from the contact element to the environment. This means that, in the best case scenario, high current levels can be transmitted, without a possible and additionally provided temperature monitoring device responding. This has basically proven itself.
- the invention is based on the technical problem of further developing such a connector part in such a way that a compact structure with cost advantages achieved compared to the prior art is observed.
- a generic connector part is characterized in the context of the invention in that at least one area of the housing that reaches the contact element is designed as a heat transport element.
- the area in question and reaching the contact element is generally designed so that it encloses the contact element.
- the procedure is such that the area in question and which forms the heat transport element has an increased thermal conductivity compared to the rest of the housing. Special measures are required for this because the area in question and the housing are made entirely of plastic and therefore any heat transport occurs rather slowly.
- the housing made of plastic
- the charging socket typically implemented at this point also functions and is designed as a heat transport element or heat capacity element, at least in the area approaching the contact element.
- the invention as a whole is based on the knowledge that the housing for the connector part is generally made of a thermoplastic.
- a design as a plastic injection molded part has proven to be particularly favorable.
- thermoplastics such as PP (polypropylene), PA (polyamide), PBT (polyethylene theraphthalate), PE (polyethylene), etc.
- thermal conductivities typically have thermal conductivities that for polypropylene (PP), for example, are 0.23 W/(m ⁇ K) or even for polyamides up to 0.35 W/(m ⁇ K). In connection with polyethylene, values of approx. 0.5 W/(m ⁇ K) are observed.
- PP polypropylene
- the area of the housing that functions as a heat transport element and reaches up to the contact element can now be made from a modified plastic in such a way that the plastic used is one with embedded fillers to increase the thermal conductivity.
- Suitable fillers in this context can be those that are designed to be electrically insulating and at the same time thermally conductive. These include, for example, aluminum compounds or drill compounds, particularly preferably aluminum oxide or boron nitrite. This allows the thermal conductivity of the plastic in question to be increased by at least a factor of 3.
- the relevant thermally conductive fillers in the plastic can be provided in a grammage of up to 50% by weight or more, so that overall thermal conductivities of significantly more than 1 W/(m ⁇ K) can be achieved. Further details on this and on suitable fillers and plastics can be found in the relevant information at this point and relevant prior art according to DE 10 2007 037 316 A1, which deals with thermally conductive and electrically insulating thermoplastic compounds, i.e. plastics with the embedded fillers. In addition, reference may be made at this point to DE 10 2013 208 605 A1.
- the invention provides as a further alternative or additional possibility that the area in question has at least one channel with a fluid located therein having.
- the fluid is generally designed to be thermally conductive and electrically insulating at the same time.
- Suitable fluids in this context are, for example, oils and in particular so-called transformer oils.
- the invention also proposes in this context that the channel in question has at least one path outside the area and the housing that accommodates it. This can further improve the heat emission.
- the area of the housing in question that functions as a heat transport element or heat capacity element is typically a flange that accommodates the contact element.
- the flange generally has a predominantly vertical plane extension compared to the contact element passing through the flange. That is, the longitudinal extent of the contact element and the extent of the plane forming the flange are predominantly arranged perpendicular to one another.
- the flange in question is embedded in a front cover of the housing surrounding it.
- the front cover of the housing - like the rest of the housing - may be made of thermoplastic without any embedded fillers be trained.
- the storage of fillers is basically reduced to the area or flange.
- the entire housing is made from the modified thermoplastic with the embedded fillers. For cost reasons, however, the storage of the fillers will be limited to the area or the flange of the housing that acts as a heat transport element and reaches up to the contact element.
- a connector part is provided for mechanical and electrical connection with a mating connector part and in particular a motor vehicle-side charging socket, which does not require any extensive attachments or installations and at the same time can be manufactured particularly cost-effectively.
- the plastic with the embedded fillers, as well as the plastic for the rest of the housing can be produced and processed by plastic injection molding.
- the ingredients required at this point, i.e. H. the fillers as well as the fluid used in the channel are designed to be inexpensive, so that in addition to a particularly compact design, a lower manufacturing price is achieved compared to the prior art. This is where the main advantages can be seen.
- FIG. 1 shows the connector part according to the invention in the form of a motor vehicle charging socket in a front view
- Fig. 2 shows the corresponding rear view of Fig. 1,
- Fig. 3 shows the object according to Figs. 1 and 2 in individual representations and 4A-4C another modified embodiment.
- the plug connector part according to the exemplary embodiment in FIGS. 1 and 2 is a charging socket 1 on the motor vehicle side.
- the charging socket 1 is set up for coupling with a charging plug, which is not shown in detail and represents part of an electrical charging infrastructure for electric or hybrid motor vehicles.
- the charging socket 1 is equipped with a housing 2 made of plastic and at least one electrical contact element 3 arranged in the housing 2.
- a housing 2 made of plastic
- at least one electrical contact element 3 arranged in the housing 2.
- the additional electrical contact elements 4 provided, which are required for an AC charging process, are not subject to any further problematization.
- the two electrical contact elements 3 inside the housing 2 are equipped with a heat transport element 5, 6.
- the heat transport element 5, 6 is in thermal contact with the electrical contact element 3.
- At least one area 5 of the housing 2 that reaches the contact element 3 is designed as a heat transport element 5.
- the region 5 in question or the heat transport element 5 encloses the contact element 3, as the illustration in FIG. 3 makes clear.
- the area 5 in question has an increased thermal conductivity compared to the rest of the housing 2.
- the invention achieves this in such a way that the area 5 in question is made of a plastic with embedded fillers to increase the thermal conductivity.
- the area 5, which is designed as a flange 5 receiving the contact element 3 is produced by injection molding from a thermoplastic such as PP, PE, etc. and embedded fillers in the form of, for example, aluminum oxide or boron nitrite.
- the contact element 3 is a cylindrical charging pin in the exemplary embodiment.
- the flange 5 made of plastic with the embedded fillers is penetrated by the relevant contact element 3.
- the flange 5 according to the exemplary embodiment is additionally equipped with radial ribs 5a surrounding the contact element 3 and which are connected to the flange 5. It can also be seen that the flange 5 in question is embedded in a surrounding front cover 2a of the housing 2, as the illustration in FIG. 3 makes immediately clear.
- the procedure is such that the heat transport element 5, 6 is designed as a fluid 6.
- the fluid 6 in question is found in a channel 7, which is provided in the area of the housing 2 designed as a heat transport element 5 or flange 5.
- the fluid 6 in question inside the channel 7 can be one that is designed to be both thermally conductive and electrically insulating. Oil and especially transformer oil is typically used at this point.
- the channel 7 can also be equipped with a path 7a outside the area 5 in question or the flange 5 and consequently also outside the housing 2. In this way, a particularly effective heat dissipation via the path 7a outside the housing 2 of the charging socket 1 is provided and observed.
- a total of two different circuits and associated channels 7 can be used for both The contact elements 3 shown in each case can be realized, as can be seen from FIG. 4A. 4B shows another possible guidance of the fluid 6 within the channel 7 or the several channels 7.
