(54) | ELECTRIC COMPRESSOR AND METHOD FOR MANUFACTURING ELECTRIC COMPRESSOR |
(57) An object is to provide an electric compressor with which the need to process an
external surface of a housing can be eliminated, making it possible to reduce time
and labor involved in processing, and with which a protection member can easily be
mounted to the external surface of the housing, and to provide a manufacturing method
of an electric compressor. An electric compressor (1) comprises: a housing (2) having
a curved external surface; an electric terminal (3) provided at the external surface
of the housing; pin-like bolts (4a and 4b) that protrude from the external surface
of the housing in a normal direction of the external surface; and a terminal guard
(5) in which apertures (7a and 7b) that correspond to the positions and protruding
directions of the bolts are formed, and that surrounds the electric terminal with
the bolts being inserted into the apertures. |

{Description of Embodiment}
{Reference Signs List}
a housing having a curved external surface;
an electric terminal provided at the external surface of the housing;
a pin-like protrusion that protrudes from the external surface of the housing in a normal direction of the external surface; and
a protection member that has an aperture which corresponds to the position and a protruding direction of the protrusion, and that surrounds the electric terminal in a state in which the protrusion is inserted into the aperture.
a sealing member that is installed between the external surface of the housing and the protection member,
wherein the protrusions include two first protrusions arranged in the circumferential direction of the external surface and one second protrusion that is provided at a position apart in an axial direction of the external surface with respect to the first protrusions, and
two first apertures are formed in the sealing member so that the first apertures individually correspond to one of the first protrusions and the second protrusion and that the sealing member is supported by the two positions.
a step of inserting the protrusion through the sealing member;
a step of wrapping a noise insulation member on the external surface of the housing after inserting the protrusion through the sealing member;
a step of connecting a cable to the electric terminal of the housing that has been wrapped with the noise insulation member; and
a step of mounting the protection member to the external surface of the housing in which the cable is connected to the electric terminal.
