The body includes a upper body portion and a base connected to each other. The core includes a first circuit board assembly and a second circuit board assembly. The first circuit board assembly is accommodated inside the base and potted with a high thermal conductivity material. The insertion plate assembly includes insertion plates and wiring terminals and is mounted via a middle support frame above the first circuit board assembly. The second circuit board assembly is mounted via a grounding frame above the middle support frame. The grounding frame includes a U shaped notch that drops toward the base to accommodate the second circuit board assembly. The second circuit board assembly is electrically coupled to the first circuit board assembly through the wiring holes of the grounding frame. ## Claims ### Claim 1 A wall mounted power supply receptacle device, comprising: a body;
