Abstract

The present invention relates to an electromotive terminal device. The electromotive terminal device inserted into a seating part of a compressor casing in which an electromotive part is installed in an inner space thereof includes: a hermetic terminal in which a plurality of terminal pins for transmitting external power into the electromotive part are arranged spaced apart from each other in the length direction thereof; and a connector having a plurality of terminal grooves electrically connected so as to correspond to the terminal pins of the hermetic terminal. A coupling groove is formed in the inner surface of the seating part of the compressor casing. The electromotive terminal device further includes a pair of snap rings, each having a circular ring shape with an opened structure at both ends thereof which are bent inward to face each other, wherein the pair of snap rings hook both ends of the hermetic terminal in a state where the snap rings are inserted into the coupling groove to face each other so as to fix the hermetic terminal to the seating part of the casing. As described above, in the terminal device for an electromotive compressor, the coupling groove is formed in the inner surface of the seating part of the compressor casing, and the hermetic terminal is hooked and fixed through the snap rings inserted into the coupling groove in the state where the hermetic terminal is inserted into the seating part. Thus, the hermetic terminal may be easily fixed to the casing.
