Electric device comprising a sealed housing having a lower housing part and an upper housing part

An electric device, comprising:

• an electric component;
• and
• a housing having a lower housing part and an upper housing part, the electric component is supported on the lower housing part, the lower housing part and the upper housing part surround a housing volume in which the electric component is sealingly encased, a weld is formed between the upper housing part and the lower housing part, one of the lower housing part and the upper housing part has a protrusion welded to another one of the lower housing part and the upper housing part, a gap is disposed between the lower housing part and the upper housing part, the gap extending radially outward from the protrusion to an outside of the housing and radially inward to an inner side of the housing, a solidified molten material from the weld is at least partially received in the gap, wherein:
• the protrusion is received in a notch of the other one of the lower housing part and the upper housing part, the notch defining interior surfaces opposing one another in a radial direction;
• the lower housing part and the upper housing part are completely separated from one another in an axial direction perpendicular to the radial direction except where a surface of the protrusion directly abuts an opposing surface of the other one of the lower housing part and the upper housing part in the axial direction, and the solidified molten material from the weld connects the upper housing part and the lower housing part.
