|20140111299||TEMPEATURE SWITCH - In a temperature switch according to the present invention, a base member made of an insulative resin and a switch configuration are integrated into one body with insert molding, and accommodated within a housing. A terminal fixing part of the base member blocks an opening of the housing vertically to an interior surface of the housing, and a sealing member seals the opening of the housing from an exterior surface of the housing. A first external connection terminal (a second external connection terminal is similar) prevents externally pulling and pressing forces applied to the terminal from applying to an internal configuration in a state where a portion formed by being bent into two stages composed of a horizontal part continuous with a tip, a vertical part, and a horizontal part is buried in the terminal fixing part. A stage difference part that is flattened and formed outside the terminal, and cutout parts on a side absorb a distortion caused by external forces applied to the terminal in upper, lower, right and left directions. Internal extension parts, and an external extension part strengthen the fixing of a position of the terminal fixing part.||04-24-2014|
|20140104730||MOTOR PROTECTOR - A motor protector of the present invention includes: a serial current path that is formed between a first terminal and a second terminal and that sequentially connects a fixed contact, the first terminal, a movable contact, a movable plate holding a bimetallic element, an intermediate fixing plate, a first electrode section, a first resistor, a second electrode section, and the second terminal, the fixed contact being held by a base member stored in an insulating resin case that includes an opening sealed by the sealing member; and a parallel current path that is formed between the first terminal and the intermediate fixing plate and that sequentially connects the first terminal, a conductive bottom plate, a second resistor (PTC)||04-17-2014|
|20130076480||THERMAL PROTECTOR - A movable contact of a movable plate rises and separates from a fixed contact when a bimetal of the thermal protector inversely warps at a predetermined temperature, an electric current between the contacts, namely, an electric current between a movable contact side terminal and a fixed contact side terminal is disrupted, and the disrupted current flows into the polymer PTC, which is then made to produce heat and is thermally expanded to increase a resistance value. A second terminal member on a side opposite to a first terminal member where the polymer PTC is positioned and fixed forms a bowing part, and a gap h is formed between an upper inner wall of a housing and the second terminal member.||03-28-2013|

|20120212210||ELECTRIC CIRCUIT CONNECTED TO THERMAL SWITCH WITH THREE TERMINALS AND SWITCH CONNECTING METHOD - An electric circuit connected to a thermal switch with three terminals and a method for connecting the switch are realized. In an electric circuit||08-23-2012|
|20120032773||THERMAL PROTECTOR - A thermal protector has superiority in current responsiveness or thermal responsiveness with a simple configuration that does not need a separate manufacturing step of incorporating a resistor. At a stage of press processing for cutting from an original material, a movable plate body part||02-09-2012|

|20100308954||THERMAL PROTECTOR - A movable contact of a movable plate rises and separates from a fixed contact when a bimetal of the thermal protector inversely warps at a predetermined temperature, an electric current between the contacts, namely, an electric current between a movable contact side terminal and a fixed contact side terminal is disrupted, and the disrupted current flows into the polymer PTC, which is then made to produce heat and is thermally expanded to increase a resistance value. A second terminal member on a side opposite to a first terminal member where the polymer PTC is positioned and fixed forms a bowing part, and a gap is formed between an upper inner wall of a housing and the second terminal member.||12-09-2010|
|20100026446||Thermal protector - The rear end of a movable plate is fixed to one end of a resin base and a pair of terminals for connection with an external circuit is fixed to the other end thereof. Fixed contacts are formed on the fixed portions of the terminals, and the movable contact of the movable plate is disposed opposed to the fixed contacts. A bimetal element engaged with the center of the movable plate is set to project upward at normal temperature, thus bringing the movable contact into pressure contact with the fixed contacts with prescribed contact pressure. The bimetal element consists of an inversion area which has no portion overlapping the conduction path area of load current, in a disposition space inside a housing, of the thermal protector, it is not affected by Joule's heat from the conduction path.||02-04-2010|
|20090102596||Temperature switch - In the temperature switch, a cut-out portion of the substrate is formed of a first cut-out portion and a second cut-out portion which are made from the side part toward the center. At the fixation part of a movable plate in the temperature switch, a pawl part and an elastic locking part having an L-shaped cross section are formed adjacent to the pawl part on the upstream side in the sliding direction, as indicated by the arrow q. When the pawl part is fitted in the second cut-out portion, a tip of the elastic locking part abuts an end portion-top surface of the substrate and the elastic locking part reversibly warps upwardly.||04-23-2009|
