초록 ▼

A hermetic electrical terminal construction adapted for connection to the outer housing of a hermetic motor compressor unit so that current may be carried to the compressor motor from an external source. The terminal comprises a body member welded or otherwise secured to the compressor outer housing and a plurality of conductor pins secured to and extending through the body member. Each of the conductor pins, which may be made of stainless steel, copper or other suitable material, comprises a first segment disposed within the housing, a second segment disposed outside the housing, and an intermediate segment connecting the first and second segments, the intermediate segment being disposed primarily within the body member. Electrical insulating and sealing material, such as glass or epoxy potting, surrounds the pin intermediate segment and forms a hermetic seal between the pin intermediate segment and the body member. The intermediate segment has a larger transverse cross-sectional area than the segment disposed outside the compressor housing with a concomitant larger current carrying capacity so that under irreversible overcurrent conditions, the normal diameter external segment will melt thereby interrupting the supply of current. Since the intermediate portion is of a greater current carrying capacity, it will remain intact and the seal between the potting material and pin will not be disturbed so that the pressurized refrigerant within the compressor housing will not be discharged.

In a hermetic motor compressor unit having an outer housing with an opening therein, a hermetically sealed terminal adapted for carrying electric current into said housing comprising: a body member closing the housing opening, said body member having at least one opening therein communicating from the exterior to the interior of the housing; a metallic conductor pin disposed in said body member opening and passing through said body member, said conductor pin comprising a first segment disposed at least partially in said housing and having a first transverse cross-sectional area and a second segment disposed at least partially outside said housing joined to and integral with said first segment and having a second transverse cross-sectional area smaller than the first cross-sectional area, the transverse cross-sectional area of said second segment being such that the current carrying capacity thereof is capable of meeting the requirements of the compressor motor but will melt under irreversible overcurrent conditions and the transverse cross-sectional area of the first segment being such that the current carrying capacity thereof is sufficiently great that it will not melt under irreversible overcurrent conditions, said first and second segments forming a shoulder at the point where they are joined wherein the shoulder faces in a direction externally of the housing; and a continuous block of electrical insulating and sealing material encasing a portion of said first segment, a portion of said second segment and said shoulder and forming a hermetic seal between the encased portions of the pin and said body member, only a small portion of the pin second segment beyond said shoulder being encased by said block of insulating material relative to the portion of the first segment encased thereby, whereby the probability of burning through of said second segment within said block of insulating material is diminished; the electrical insulating and sealing material having a higher melting temperature than the conductor pin first segment.
