1. A compressor for compressing a refrigerant, the compressor comprising:
a case having at least one curved portion and at least one opening, wherein the at least one opening is located in the at least one curved portion;
an electrical terminal arranged within the at least one opening and fixed to the case, wherein the electrical terminal comprises a body, at least one connection pin, which is isolated from the body by ease of an insulator, and a protrusion for attaching the electrical terminal to the case, wherein the protrusion extends from the body and reaches into the case;
wherein the at least one opening is an elliptical opening, the elliptical opening having a minor axis and a major axis and being curved along its major axis;
wherein the electrical terminal is fixed to the case by ease of a sealed connection being formed between the case and the electrical terminal, wherein the sealed connection is formed by placing the electrical terminal in the elliptical opening and welding the protrusion of the electrical terminal to a portion of the case, wherein a gap between the body of the electrical terminal and a boundary of the elliptical opening is larger along the major axis of the elliptical opening than along the minor axis of the elliptical opening.
