本発明は、前記課題を解決するために以下の構成を採用した。すなわち、第１の発明に係る温度センサは、一対のリードフレームと、一対の前記リードフレームの先端部に接続され感熱素子を有するセンサ部と、前記センサ部の表裏面を覆った絶縁性の一対の保護フィルムとを備え、前記センサ部が、絶縁性フィルムと、前記絶縁性フィルムの一方の面に設けられサーミスタ材料で形成されたサーミスタ部と、前記サーミスタ部に互いに対向して形成された一対の対向電極と、一端が一対の前記対向電極に接続され前記絶縁性フィルムの一方の面に形成された一対のパターン電極とを備え、一対の前記保護フィルムが、一対の前記リードフレームの先端部と共に前記センサ部を挟んで互いに全周が熱融着されていることを特徴とする。 The present invention employs the following configuration in order to solve the above problems. That is, the temperature sensor according to the first aspect of the present invention is a pair of lead frames, a sensor unit having a thermal element connected to the tip portions of the pair of lead frames, and an insulating pair covering the front and back surfaces of the sensor unit. and a protective film, the sensor part, an insulating film, wherein the one support is formed of a thermistor material disposed on the surface Misuta portion of the insulating film, is formed to face each other in the thermistors portion A pair of counter electrodes, and a pair of pattern electrodes having one end connected to the pair of counter electrodes and formed on one surface of the insulating film, and the pair of protective films of the pair of lead frames. The entire circumference of the sensor unit is heat-sealed with the tip part interposed therebetween.
第３の発明に係る温度センサは、第１又は第２の発明において、前記サーミスタ部が、前記絶縁性フィルムの一方の面にサーミスタ材料でパターン形成された薄膜サーミスタ部であることを特徴とする。
第４の発明に係る温度センサは、第３の発明において、前記薄膜サーミス部上に形成された絶縁性の保護膜を備え、前記保護フィルムが、前記保護膜にも熱融着されていることを特徴とする。
すなわち、この温度センサでは、保護フィルムが、保護膜にも熱融着されているので、さらに高い密着性と耐湿性とを得ることができる。
A temperature sensor according to a third invention is characterized in that, in the first or second invention, the thermistor portion is a thin film thermistor portion patterned with a thermistor material on one surface of the insulating film. .
A temperature sensor according to a fourth invention is the temperature sensor according to the third invention, further comprising an insulating protective film formed on the thin film thermist portion, wherein the protective film is also thermally fused to the protective film. It is characterized by.
That is, in this temperature sensor, since the protective film is also heat-sealed to the protective film, higher adhesion and moisture resistance can be obtained.
第５の発明に係る温度センサは、第１から第４の発明のいずれかにおいて、前記保護フィルムが、フッ素系樹脂で形成されていることを特徴とする。
すなわち、この温度センサでは、保護フィルムが、フッ素系樹脂で形成されているので、高い防湿性と滑り性とが得られる。特に、本発明の温度センサは、定着ローラ等の回転する測定対象物に接触させて温度測定する際に好適である。また、防湿性が高いため、保護フィルムを従来よりも薄くすることができ、熱容量が小さくなって応答性を向上させることも可能になる。
A temperature sensor according to a fifth invention is characterized in that, in any one of the first to fourth inventions, the protective film is made of a fluorine-based resin.
That is, in this temperature sensor, since the protective film is formed of a fluorine-based resin, high moisture resistance and slipperiness can be obtained. In particular, the temperature sensor of the present invention is suitable for measuring a temperature by bringing it into contact with a rotating measuring object such as a fixing roller. Moreover, since moisture-proof property is high, a protective film can be made thinner than before, a heat capacity becomes small, and it also becomes possible to improve responsiveness.
本実施形態の温度センサ１は、図１から図４に示すように、一対のリードフレーム２と、一対のリードフレーム２の先端部２ａに接続され感熱素子を有するセンサ部３と、センサ部の表裏面を覆った絶縁性の一対の保護フィルム８とを備えている。
上記センサ部３は、絶縁性フィルム４と、絶縁性フィルム４の一方の面（上面）にサーミスタ材料でパターン形成された薄膜サーミスタ部５（サーミスタ部）と、薄膜サーミスタ部５の上に互いに対向して形成された一対の対向電極６と、一端が一対の対向電極６に接続され絶縁性フィルム４の一方の面に形成された一対のパターン電極７と、薄膜サーミスタ部５上に形成された絶縁性の保護膜１０とを備えている。
なお、本発明では、絶縁性フィルム４の一方の面側を、表面側又は上面側として記載している。
As shown in FIGS. 1 to 4, the temperature sensor 1 of the present embodiment includes a pair of lead frames 2, a sensor unit 3 having a thermal element connected to the distal end portions 2 a of the pair of lead frames 2, And a pair of insulating protective films 8 covering the front and back surfaces.
The sensor unit 3 is opposed to the insulating film 4, the thin film thermistor unit 5 (thermistor unit) patterned with the thermistor material on one surface (upper surface) of the insulating film 4, and the thin film thermistor unit 5. Formed on the thin film thermistor portion 5 and a pair of pattern electrodes 7 formed on one surface of the insulating film 4 with one end connected to the pair of counter electrodes 6. And an insulating protective film 10.
In addition, in this invention, the one surface side of the insulating film 4 is described as the surface side or the upper surface side.
