Description of the Related Art Hermetic electric compressors are generally designed to have the smallest external dimensions, so the internal space is small and the motor leads can come into contact with other parts inside the compressor or with the inner wall of the compressor case. There is. In such a case, the heat at the time of welding and sealing the compressor case may melt the insulation on the lead wire surface,
The insulation during the operation of the compressor may cause insulation failure on the lead wire surface, resulting in insulation failure.
It has been devised to use a tubular lead wire protection member as shown in -50410 or to use a lead wire locking member as shown in Japanese Utility Model Application Laid-Open No. 51-5613.

る。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is directed to bending an approximately rectangular refrigerant-resistant thin plate made of an insulating material in the vicinity of a center portion, and forming an internal lead of an electric motor at a substantially center portion of two overlapping flat surfaces. A hole having a size through which the wire easily passes is provided, and the lead wire is inserted into the hole so that the bending angle between the two planes is set to 50 to 130 degrees.
The one that has been set at a certain time is disposed in the compressor case.

なくなる。According to the above configuration, by setting the bending angle formed by the two planes after the lead wire is inserted between 50 degrees and 130 degrees, the six corners forming the two planes are formed by the length of the lead wire. Since the lead wire is scattered in a wide range in the vertical direction and forms a cube, the lead wire inserted into the hole at the center does not contact other parts in the compressor case or the inner wall of the compressor case.
