AI summary

There is described a modular connector receptacle comprising a shield and a modular connector assembly. The shield comprises an electrically-conductive material, and comprises a lumen defining an inner surface which comprises a thread. The modular connector assembly comprises peripheral winglets which engage with the thread of the inner surface of the lumen for screwably housing the modular connector assembly inside the shield. The peripheral winglets are electrically conductive, thus providing a ground. Low-pass filters are provided on a PCB in the modular connector assembly, and the PCB comprising the low-pass filters can have a PCB shield enclosing the PCB and electrically connected to the peripheral winglets for grounding to the shield.
