摘要： A protector for a three-phase electric motor has a container with a housing and a metal plate secured thereto. A protrusion is provided in the housing. Three conductive terminal pins, each with a fixed contact, protrude into the housing through the metal plate. A thermally responsive plate is connected to the three moveable contacts. The thermally responsive plate is dish shaped and reverses its direction of curvature at a predetermined temperature. Three moveable contacts are secured to the thermally responsive plate. An elastic member extends between the protrusion and the thermally responsive plate. A rotation member prevents the thermally responsive plate from rotating, thereby maintaining the moveable contacts in opposition to the fixed contacts. The conductive terminal pins are located at a neutral point side of phase windings of a three-phase motor so that AC current flowing into the three-phase motor is interrupted.

摘要： A three-phase thermal protector includes a hermetic receptacle composed of an elliptic dome-shaped cover having an opening at one end and a header plate having two terminal pins extending through respective apertures formed in it, and a switch assembly mounted in the receptacle. Two fixed contacts are secured to the respective terminal pins. The switch assembly includes a metal operating temperature calibrating plate with one end welded to the cover, a bimetallic thermally responsive element having one end secured to the calibrating plate and the other end having a central dish-shaped portion, and a thermally-responsive-element support to which the supported end of the thermally responsive element is welded. The thermally responsive element carries two movable contacts symmetrical about the center line. The calibrating plate has a push projection pushing the thermally responsive element so that the contact pressure is increased when the calibrating plate is deformed with deformation of the cover for the calibration of the operating temperature. The header plate has a protrusion receiving the thermally responsive element at a position away from its supported end toward the center.

摘要： A thermal protector includes a header plate and a metal housing having an open end hermetically welded to an peripheral edge of the header plate. The housing is formed into a generally slender shape so as to be suited for mounting on end turns of a stator winding of a three-phase electric motor. A thermally responsive element includes a shallow curved portion at which the element changes states of curvature with snap action in response to different ambient temperatures. The thermally responsive element has two movable contacts secured to it to be disposed symmetrically about a center of the curved portion so that the movable contacts are engageable with and disengageable from fixed contacts respectively. A push piece is disposed in the housing to exert a pushing force on a normally convex side of the thermally responsive element. The pushing force is adjusted by deforming the outer surface portion of the housing for calibration of the operating temperature. The push piece includes a portion secured to an inner surface of the housing so as to correspond substantially to the deformed outer surface portion of the housing for calibration of the operating temperature.

摘要： A thermal protector for a hermetic electrically-driven compressor includes a thermal switch and a cluster socket. The protector is mounted inside a compressor housing on a terminal assembly mounted in a wall of the compressor housing. A casing of the thermal switch and a header plate hermetically closing an open end of the casing integrally form a flange on the peripheral edges when the header plate is secured to the casing. The thermal switch has two terminals one of which is provided with a receptacle into which one of terminal pins of the terminal assembly is fitted, and the other terminal is connected to a common lead wire of a compressor motor. The cluster socket has a plurality of terminal cavities for connecting windings of the motor to the terminal assembly. A body of the socket has a face having a pair of holding portions for holding the flange. Each holding portion has a hook-shaped portion at an end. The casing and the socket are integrally connected together such that a large part of the casing is exposed outside the socket body, when the flange is held by the holding portions and the receptacle is inserted to a position where it is opposed to the one terminal pin of the terminal assembly.
