Abstract

A charging inlet assembly for an electric vehicle includes a housing having a power connector including AC terminals and DC terminals. An AC terminal assembly is coupled to the housing and includes AC bus bars electrically connected to corresponding AC terminals at a separable mating interface. A DC connector is mechanically and electrically connect to the DC contact of the DC connector at a separable mating interface.

First claim

What is claimed is:

1. A charging inlet assembly for an electric vehicle comprising:
a housing extending between a front and a rear, the housing having a chamber at the rear, the housing having a power connector at the front for receiving a charging connector, the power connector including AC terminal channels and DC terminal channels between the front and the rear;
AC terminals coupled to the housing, each of the AC terminals including a mating pin and a terminating end opposite the mating pin, the mating pin positioned in the corresponding AC terminal channel for mating with the charging connector, the terminating end positioned in the chamber at the rear of the housing;
an AC terminal assembly received in the housing, the AC terminal assembly including AC bus bars electrically connected to corresponding AC terminals, each of the AC bus bars including a separable mating interface configured to be electrically connected to AC contacts of an AC connector removably coupled to the housing; and
DC terminals coupled to the housing, each of the DC terminals including a mating pin and a terminating end opposite the mating pin, the mating pin positioned in the corresponding DC terminal channel for mating with the charging connector, the terminating end positioned in the chamber at the rear of the housing, the terminating end including a threaded element configured to mate with a mating threaded element of a DC connector to mechanically and electrically connect to a DC contact of the DC connector removably coupled to the housing.

2. The charging inlet assembly of claim 1 , wherein the threaded elements include threaded bores configured to receive threaded fasteners defining the mating threaded elements.

3. The charging inlet assembly of claim 1 , wherein the threaded elements allow the DC connector to mate to and unmate from the housing without removing the DC terminals from the housing.

4. The charging inlet assembly of claim 1 , wherein the housing includes a DC connector shroud including a receptacle configured to pluggably receive the DC connector, the terminating ends of the DC terminals being exposed in the DC connector shroud for mating with the DC connector.

5. The charging inlet assembly of claim 1 , wherein the housing includes an AC connector shroud including a receptacle configured to pluggably receive the AC connector, the terminating ends of the AC terminals being exposed in the AC connector shroud for mating with the AC connector.

6. The charging inlet assembly of claim 1 , wherein the AC bus bars are right angle bus bars configured to mate with the AC connector in a mating direction perpendicular to the AC terminals.

7. The charging inlet assembly of claim 1 , wherein the AC bus bars each include a first mating end and a second mating end, the first mating end being electrically connected to the corresponding AC terminal, the second mating end including a blade defining the separable mating interface of the corresponding AC bus bar.

8. The charging inlet assembly of claim 1 , wherein the AC terminal assembly includes a printed circuit board, at least one of the AC terminals being electrically connected to the printed circuit board.

9. The charging inlet assembly of claim 8 , wherein the AC terminal assembly includes at least one of a pilot terminal and a proximity terminal extending to the front of the housing for connecting with the charging connector and being electrically connected to the printed circuit board.

10. A charging inlet assembly for an electric vehicle comprising:
a housing extending between a front and a rear, the housing having a chamber at the rear, the housing having a power connector at the front for receiving a charging connector, the power connector including AC terminal channels and DC terminal channels between the front and the rear;
AC terminals coupled to the housing, each of the AC terminals including a mating pin and a terminating end opposite the mating pin, the mating pin positioned in the corresponding AC terminal channel for mating with the charging connector, the terminating end positioned in the chamber at the rear of the housing;
an AC terminal assembly received in the housing, the AC terminal assembly including AC bus bars electrically connected to corresponding AC terminals, each of the AC bus bars including a mating interface;
an AC connector having an AC connector housing coupled to the rear of the housing, the AC connector including AC contacts held by the AC connector housing, the AC connector including AC power cables extending into the AC connector housing being terminated to the AC contacts, each of the AC contacts having a separable contact interface mated with the mating interface of the corresponding AC bus bar when the AC connector is coupled to the housing and unmated from the AC bus bar when the AC connector is uncoupled from the housing;
DC terminals coupled to the housing, each of the DC terminals including a mating pin and a terminating end opposite the mating pin, the mating pin positioned in the corresponding DC terminal channel for mating with the charging connector, the terminating end positioned in the chamber at the rear of the housing; and
a DC connector having at least one DC connector housing coupled to the rear of the housing, the DC connector including DC contacts held by the DC connector at least one housing, the DC connector including DC power cables extending into the at least one DC connector housing being terminated to the DC contacts, each of the DC contacts having a separable contact interface configured to be electrically connected to the corresponding DC terminal.

11. The charging inlet assembly of claim 10 , wherein the at least one DC connector housing includes a single DC connector housing having a cavity receiving each of the DC contacts and each of the DC power cables.

12. The charging inlet assembly of claim 10 , wherein the at least one DC connector housing includes a plurality of DC connector housings independently coupled to the housing, each DC connector housing including a single one of the DC contacts and a single one of the DC power cables.

13. The charging inlet assembly of claim 10 , wherein the DC connector includes seals coupled to the at least one DC connector housing, the seals engaging the housing to provide a sealed mating interface between the DC connector and the housing.

14. The charging inlet assembly of claim 10 , wherein the terminating ends of the DC terminals include threaded elements, the DC connector including threaded elements configured to mate with the threaded elements of the DC terminals to mechanically and electrically connect the DC contacts to the DC terminals.

15. The charging inlet assembly of claim 10 , wherein the housing includes a DC connector shroud including a receptacle configured to pluggably receive the DC connector, the terminating ends of the DC terminals being exposed in the DC connector shroud for mating with the DC connector.

16. The charging inlet assembly of claim 10 , wherein the housing includes an AC connector shroud including a receptacle configured to pluggably receive the AC connector, the terminating ends of the AC terminals being exposed in the AC connector shroud for mating with the AC connector.

17. The charging inlet assembly of claim 10 , wherein the AC bus bars each include a first mating end and a second mating end, the first mating end being electrically connected to the corresponding AC terminal, the second mating end including a blade defining the separable mating interface of the corresponding AC bus bar.
