[0049] about Figures 4 to 6 For other parts of the exemplary embodiment shown, please refer to the above description of Figures 4 to 6 The corresponding contents in the exemplary embodiments shown will not be repeated here.

[0050] It should be noted that the shielded electrical connector described in the exemplary embodiment of the present disclosure is an example of a heavy-duty power supply and signal hybrid connector. Figures 1 to 3 In the exemplary embodiment shown, the shielded electrical connector is a male plug-in electrical connector 1; Figures 4 to 6In the exemplary embodiment shown, the shielded electrical connector is a female ferrule electrical connector 2. Furthermore, herein, the first and second contact terminals in the shielded electrical connector can be the power contact terminals and signal contact terminals, respectively, of a heavy-duty hybrid power and signal connector in the prior art. Therefore, their structures and functions are identical or similar to those of the power contact terminals and signal contact terminals in the prior art, and therefore will not be further described or illustrated herein.

[0051] At the same time, the present disclosure also provides a Figures 4 to 6 The electrical connector assembly is composed of the female ferrule electrical connector 1 shown.
