- the shallow trained connecting portion 34 of the ring shoe designed as a cable protective conductor terminal 32 is used to connect the protective conductor terminal 32 to the cooling device 30.
- the protective conductor 120 is at least partially connected electrically to the cooling device 30.
- the protective conductor contact 20 is at least partially galvanically connected to the cooling device 30. This is reali in the illustrated embodiment, characterized in that the protective conductor contact 20 is connected to a front side 37 of the cooling device 30 directly to the cooling device 30. More specifically, the protective conductor contact 20 is screwed into the front side 37 of the cooling device 30.
- the protective conductor contact 20, thedeein device 30 and the protective conductor terminal 32 are arranged such that the protective conductor contact 20 by means of the cooling device 30 to the protective conductor terminal 32 is electrically connected.
- the galvanic connection of the protective conductor contact 20 with the protective conductor 120 is realized so that without the cooling device 30th no such galvanic connection between protective conductor contact 20 and protective conductor 120 and, accordingly, no grounding of the charging plug 100 would be present.
- the galvanic connection between the protective conductor contact 20 and the protective conductor terminal 32 and thus ultimately to the protective conductor 120 is thus realized by the fact that the cooling device 30 is arranged between the protective conductor 20 and the protective conductor terminal 32 and connects them together.
- the protective conductor 120 is arranged in the supply cable 140.
- the supply cable 140 additionally also has at least the two charging lines not shown here, which are galvanically connected to the two power contacts 10. The charging lines and the protective conductor 120 are thus arranged together in the supply cable 140.
- a charging current is transferable, for example, from a charging station via the charging lines, the power contacts 10 (contact pins) and the contact terminals to an accumulator.
- an accumulator such as a vehicle battery of an electrically powered vehicle.
- the plug-in direction R of the charging plug 100 can also be seen. Under the plug direction R is the direction to understand in which the charging plug 100 in the assembled state with a corresponding connection device intended ge is coupled.
- the plug-in direction R is parallel to a through one of the power contacts 10 and to a defined by the protective conductor contact 20 direction.
- the plug-in direction R also extends perpendicular to the front-side contact side 115 of the charging plug housing 110 and also perpendicular to the front side 37 of the cooling device 30.
- the protective earthing and cooling system 1 according to the invention is shown in an exploded view, the illustration of FIG. 3A being shown in FIG. 2A and the representation of FIG. 3B being shown in FIG. 2B in each case neglecting the supply cable 140 corresponds.
- each only the protective line 120 is separately Darge presents.
- the protective conductor terminal 32 is mounted from above on thedeein device 30, in more detail the Schutzleiteran is circuit 32 by means of the screw 36 from above to the cooling device 30 and that on the cable side End portion 33 of the cooling device 30 connected. It is also possible to make this screw 36 even safer by the screw 36, for example, by screwing with additional parts, such as a toothed wheel, realized.
- the front side 37 of the cooling device 30 starved, cable-side end portion 33 is formed downwardly angled down. More specifically, the cable-side end portion 33 is angled relative to the plug-in direction R defined by the protective conductor contact 20, as can also be seen from FIGS. 2A and 2B, so that the cooling device 30 and thus also the protective earthing and cooling system 1 follow the subsequent course of the supply cable 140 adapted adapted. In this way, the protective earthing and cooling system 1 has an advantageous embodiment with regard to the handling of the corresponding charging plug 100.
- the protective earthing and cooling system 1 thus ensures optimum utilization of the space available in the charging plug housing interior 116 by the cooling device 30 for improved cooling of the charging plug 100, and thus for an increased current carrying capacity at the same time compact design of the charging plug 100. Due to the fact that it can be dispensed with extending through a large part of the charging plug housing 116 interior guidance of the protective conductor 120, at the same time the reliability of the charging plug 100 is improved.
- FIG. 4A is a sectional view of the charging plug 100 according to the invention with the Schufzerdungs- and cooling system 1 according to the invention.
- the charging plug 100 is shown in Fig. 1 by a vertical, centered by the charging plug 100 he stretched cutting plane shown.
- Fig. 4B shows a detail of Fig. 4A in an enlarged detail view.
- the supply cable 140 comprising the protective conductor 120 is in this case connected to the charging plug 100 by being introduced, inter alia, into the cable connection section 114 and being enclosed by the latter.
- the protective conductor 120 is further connected via the protective conductor connection 32 to the heat sink 31 of the cooling device 30 at least partially galvanically connected.
- This cooling device 31 is in turn at least partially connected galvanically to the front side passing through the base portion 113 of the mating face portion 111 of the charging connector housing 110 protective conductor contact 20, so that a galvanic connection of the protective conductor contact 20 with the protective conductor 120 by means of the cooling device 30.
- the protective conductor contact 20 passes through the base portion 113 of the mating face portion 111 at the front, at the same time being sealed against the charging connector housing 110 by means of a seal 21 extending between the mating contact 20 and the base 113 of the mating face portion 111 is. Furthermore, it can be seen in Fig. 4B that the protective conductor contact 20 in the heat sink 31, more specifically in the front side 37 of the cooling device 30, is screwed. The heat sink 31 and, accordingly, the cooling device 30 is arranged in the cable-side section 112 of the charging plug housing 110.
- the charging plug 100 shown is particularly advantageous in terms of its size and thus its handling due to the protective earthing and cooling system 1 optimally utilizing the charging plug housing interior 116.
