以下、本発明の一実施の形態における温度ヒューズについて、図面を参照しながら説明する。   Hereinafter, a thermal fuse in an embodiment of the present invention will be described with reference to the drawings.

図1は本発明の一実施の形態における温度ヒューズの一部切欠上面図、図2は図1のA−A線断面図である。   FIG. 1 is a partially cutaway top view of a thermal fuse in an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG.

図1、図2に示すように、本発明の一実施の形態における温度ヒューズは、第1の金属端子11および第2の金属端子12と、この第1、第2の金属端子11,12の互いに対向するそれぞれの先端部11a,12aに設けられた金属層13と、この金属層13と接続されるように前記第1の金属端子11と第2の金属端子12との間に橋設された可溶合金14と、前記第1、第2の金属端子11,12を上面に設けた第1の絶縁フィルム15と、前記可溶合金14の上方に位置し、かつ前記第1の絶縁フィルム15との間に内部空間を形成するように前記第1の絶縁フィルム15に接着封止により取り付けられる第2の絶縁フィルム16とを備え、そして前記第1、第2の金属端子11,12の先端部11a,12aの角部に、前記可溶合金14の一部に覆われ、かつその形状が円周の一部分である円弧状に構成された端辺17を形成したものである。   As shown in FIGS. 1 and 2, the thermal fuse in one embodiment of the present invention includes a first metal terminal 11 and a second metal terminal 12, and the first and second metal terminals 11 and 12. The metal layer 13 provided at the respective front end portions 11 a and 12 a facing each other and the bridge between the first metal terminal 11 and the second metal terminal 12 so as to be connected to the metal layer 13. The soluble alloy 14, the first insulating film 15 provided with the first and second metal terminals 11, 12 on the upper surface, the first insulating film located above the soluble alloy 14 and the first insulating film 15, and a second insulating film 16 attached to the first insulating film 15 by adhesive sealing so as to form an internal space between the first and second metal terminals 11, 12. In the corners of the tips 11a and 12a, 14 is covered in a part of, and is obtained by forming a end side 17 of the shape is configured in a circular arc shape which is the circumference of a portion.

上記構成において、前記第1、第2の金属端子11,12は、鉄、銅、ニッケルなどの導電性の良い板状の金属により平板状に構成され、そしてこの第1、第2の金属端子11,12の各先端部11a,12aは、第1の絶縁フィルム15の上面に設けられている。また、互いに対向する各先端部11a,12aの上面には、金属端子11,12に比べて可溶合金14との濡れ性が良いはんだ等の材料により構成された金属層13が形成されている。この金属層13の形成により、溶融した可溶合金14が速やかに金属層13のみへ分断されるようになっている。   In the above configuration, the first and second metal terminals 11 and 12 are formed in a flat plate shape by a plate metal having good conductivity such as iron, copper, nickel, and the first and second metal terminals. The tip portions 11 a and 12 a of 11 and 12 are provided on the upper surface of the first insulating film 15. In addition, a metal layer 13 made of a material such as solder having better wettability with the fusible alloy 14 than the metal terminals 11 and 12 is formed on the upper surfaces of the tip portions 11a and 12a facing each other. . By forming the metal layer 13, the molten soluble alloy 14 is quickly divided only into the metal layer 13.

また、前記可溶合金14は、金属層13と接続されるように第1の金属端子11と第2の金属端子12との間に橋設されている。すなわち、第1、第2の金属端子11,12と可溶合金14とは金属層13を介して接続されているものである。そして、この可溶合金14は、錫、ビスマス、インジウム、亜鉛などのうち2つ以上の金属からなる合金からなり、その周囲にはロジンを主成分とするフラックス18が塗布されている。特に、インジウム、亜鉛を含む場合は金属層13へ分断される力が小さいため、本発明の一実施の形態のように表面張力も受けるようにすれば、速断性に優れた温度ヒューズが得られるものである。   The fusible alloy 14 is bridged between the first metal terminal 11 and the second metal terminal 12 so as to be connected to the metal layer 13. That is, the first and second metal terminals 11 and 12 and the fusible alloy 14 are connected via the metal layer 13. The fusible alloy 14 is made of an alloy made of two or more metals such as tin, bismuth, indium, and zinc, and a flux 18 containing rosin as a main component is applied around the alloy. In particular, in the case of containing indium and zinc, since the force to be divided into the metal layer 13 is small, if the surface tension is also received as in the embodiment of the present invention, a thermal fuse excellent in quick disconnection can be obtained. Is.

そしてまた、前記第1、第2の絶縁フィルム15,16はポリエチレンテレフタレートなどの樹脂により平板状に構成され、そして第1の絶縁フィルム15と第2の絶縁フィルム16を超音波溶着あるいは熱圧着によって接着することにより、可溶合金14が密閉されるようにしている。また、前記端辺17は第1、第2の金属端子11,12の先端部11a,12aの角部に設けられているもので、円弧状に構成され、そしてこの端辺17は前記可溶合金14の少なくとも一部で覆われているものである。   The first and second insulating films 15 and 16 are formed in a flat plate shape using a resin such as polyethylene terephthalate, and the first insulating film 15 and the second insulating film 16 are bonded by ultrasonic welding or thermocompression bonding. The fusible alloy 14 is hermetically sealed by bonding. The end side 17 is provided at the corners of the end portions 11a and 12a of the first and second metal terminals 11 and 12, and is formed in an arc shape. It is covered with at least a part of the alloy 14.

ここで、端辺17を円弧状に構成したのは、図3に示すように、端辺17の接線Sと直交する法線Tの方向が金属端子11,12の内側に位置するようにするためである。これにより、可溶合金14が溶融温度に達して溶融したとき、可溶合金14は金属層13へ分断される力だけでなく、表面張力による金属端子11,12の内側へ引っ張られる力も受けるため、可溶合金14が溶融温度に達してから分断する(絶縁抵抗が高くなって通電しなくなる)までの時間は短くなり、これにより、速断性に優れた温度ヒューズが得られるという効果が得られるものである。   Here, the end side 17 is formed in an arc shape so that the direction of the normal T orthogonal to the tangent S of the end side 17 is located inside the metal terminals 11 and 12 as shown in FIG. Because. As a result, when the fusible alloy 14 reaches the melting temperature and melts, the fusible alloy 14 receives not only the force to be divided into the metal layer 13 but also the force to be pulled inside the metal terminals 11 and 12 due to the surface tension. The time from when the fusible alloy 14 reaches the melting temperature until it is divided (insulation resistance becomes high and the current is not supplied) is shortened, thereby obtaining the effect that a thermal fuse excellent in quick disconnection can be obtained. Is.

なお、端辺17の形状は、直線状にしても良いが、端辺17は本発明の一実施の形態のように円弧状に構成すれば、より大きな表面張力が得られるため、直線状の場合に比べてより速断性を高めることができるものである。   The shape of the end side 17 may be a straight line. However, if the end side 17 is configured in an arc shape as in the embodiment of the present invention, a larger surface tension can be obtained. Compared with the case, it is possible to improve the quick disconnection property.

また、前記端辺17は第1、第2の金属端子11,12の先端部11a,12aの角部に設けているため、切削、パンチング等により端辺17を容易に形成することができるものである。   Moreover, since the said edge 17 is provided in the corner | angular part of the front-end | tip parts 11a and 12a of the 1st, 2nd metal terminals 11, 12, the edge 17 can be easily formed by cutting, punching, etc. It is.

そしてまた、図4に示すように、端辺17の全てが曲線状となるように金属端子11,12の先端部11a,12aを円形状に構成すれば、最も大きな表面張力が得られるため、速断性をさらに高めることができ、かつ端辺17を可溶合金14で確実に覆うことができるものである。   And, as shown in FIG. 4, if the tip portions 11a, 12a of the metal terminals 11, 12 are configured in a circular shape so that all of the end edges 17 are curved, the largest surface tension can be obtained. The quick disconnection can be further improved, and the end side 17 can be reliably covered with the soluble alloy 14.

さらに、前記金属層13の形状を円形状または半円形状に構成すれば、溶融した可溶合金14が金属層13の円の中心に向って表面張力によって引っ張られるため、可溶合金14が分断されるまでに時間はかからず、より優れた速断性が得られるものである。   Furthermore, if the shape of the metal layer 13 is circular or semicircular, the meltable soluble alloy 14 is pulled by the surface tension toward the center of the circle of the metal layer 13, so that the soluble alloy 14 is divided. It does not take time to be done, and more excellent quick disconnect properties can be obtained.

本発明に係る温度ヒューズは、速断性に優れているという効果を有し、過昇温による機器の破損を防止するために使用される温度ヒューズ等として有用となるものである。   The thermal fuse according to the present invention has an effect that it is excellent in quick disconnection, and is useful as a thermal fuse used to prevent damage to equipment due to excessive temperature rise.
