以下に一実施形態に係る本発明のヒータ用防湿キャップについて、図を参照して説明する。なお、以下の実施形態は本発明のヒータ用防湿キャップの例であり、本発明のヒータ用防湿キャップは以下の実施形態に限定されるわけではない。 Hereinafter, a moisture-proof cap for a heater according to an embodiment of the present invention will be described with reference to the drawings. The following embodiments are examples of the moisture-proof cap for heaters of the present invention, and the moisture-proof cap for heaters of the present invention is not limited to the following embodiments.

(実施形態1)
図1(A)は、本実施形態に係る本発明のヒータ用防湿キャップ100の構成を示している。図1(B)は、本実施形態に係る本発明のヒータ用防湿キャップ100の分解構成図である。ヒータ用防湿キャップ100は、袋状部材102、多孔質体104、ネット状部材106及び筒状部材108を有している。
(Embodiment 1)
FIG. 1A shows a configuration of a moisture-proof cap 100 for a heater according to the present invention. FIG. 1B is an exploded configuration diagram of the moisture-proof cap 100 for heaters according to the present invention. The heater moisture-proof cap 100 includes a bag-like member 102, a porous body 104, a net-like member 106, and a tubular member 108.

ヒータ用防湿キャップ100においては、筒状部材108の側壁面周りに袋状部材102の開口部102aが密着している。なお、図1Aに示すように、袋状部材102の側壁面周りに袋状部材の開口部102aが密着する状態で、開口部102a端部と筒状部材108とを接着剤110によって固定するようにしてもよい。また、筒状部材100の側壁面周りに袋状部材102の開口部が接着剤を介して密着するようにしてもよい。 In the moisture-proof cap 100 for heaters, the opening 102 a of the bag-like member 102 is in close contact with the periphery of the side wall surface of the tubular member 108. As shown in FIG. 1A, the end of the opening 102a and the tubular member 108 are fixed by the adhesive 110 in a state where the opening 102a of the bag-like member is in close contact with the side wall surface of the bag-like member 102. It may be. Moreover, you may make it the opening part of the bag-shaped member 102 contact | adhere around the side wall surface of the cylindrical member 100 via an adhesive agent.

袋状部材102には例えばシリコンが用いられる。筒状部材108には例えばシリコンが用いられる。袋状部材102と筒状部材108が例えばシリコン等の接着材110によって密閉されている。 For example, silicon is used for the bag-like member 102. For example, silicon is used for the cylindrical member 108. The bag-like member 102 and the cylindrical member 108 are sealed with an adhesive 110 such as silicon.

袋状部材102と筒状部材108とで囲まれた領域は、筒状部材108の開口部がネット状部材106で覆われている。当該領域の内部には、例えばシリカゲル等の多孔質体104が存在する。 In the region surrounded by the bag-like member 102 and the tubular member 108, the opening of the tubular member 108 is covered with the net-like member 106. Inside the region, a porous body 104 such as silica gel is present.

本実施形態においては、袋状部材102には半透明色の材料を用いている。多孔質体104には吸湿によって無色から有色へ変化するものを用いるようにしてもよい。例えば、多孔質体104にシリカゲルを用いた場合、シリカゲルは吸湿によって無色から赤色に変化する。よって、多孔質体104の変色を視覚的に認識し、ヒータ用防湿キャップ100の防湿能力を判断することができる。 In the present embodiment, the bag-like member 102 is made of a translucent material. The porous body 104 may change from colorless to colored due to moisture absorption. For example, when silica gel is used for the porous body 104, the silica gel changes from colorless to red due to moisture absorption. Therefore, the discoloration of the porous body 104 can be visually recognized, and the moisture-proof ability of the moisture-proof cap 100 for heaters can be determined.

多孔質体104には水分を蒸発させることにより再利用が可能なものを用いてもよい。例えば、多孔質体104にシリカゲルを用いた場合、ヒータ用防湿キャップ100を加熱することにより、シリカゲル中の水分を蒸発させ、吸湿性を復活させることができる。吸湿性を復活させることにより、ヒータ用防湿キャップ100を取替て再利用することが可能になる。 As the porous body 104, a material that can be reused by evaporating water may be used. For example, when silica gel is used for the porous body 104, moisture in the silica gel can be evaporated and the hygroscopicity can be restored by heating the moisture-proof cap 100 for heaters. By reviving the hygroscopicity, the heater moisture-proof cap 100 can be replaced and reused.

図2(A)はヒータ用防湿キャップ100を取り付けたヒータを説明した図である。図2(B)とはヒータ用防湿キャップ100をヒータへ取り付けた構成を示している。ヒータ200は電極202と、封止材206と、放熱管204と、電熱線210とを有する。 FIG. 2A is a diagram illustrating a heater to which a moisture-proof cap 100 for heaters is attached. FIG. 2B shows a configuration in which a moisture-proof cap 100 for a heater is attached to the heater. The heater 200 includes an electrode 202, a sealing material 206, a heat radiating tube 204, and a heating wire 210.

本実施形態においては、放熱管204の内部には電熱線210が配置されており、電熱線210の周りには絶縁剤208が充填されている。電熱線210の先端には電極202が取付けられている。放熱管204の先端は封止材206によって封止されている。封止材には例えばシリコンが用いられる。絶縁剤には例えば酸化マグネシウム等が用いられる。 In the present embodiment, a heating wire 210 is disposed inside the heat radiating tube 204, and an insulating agent 208 is filled around the heating wire 210. An electrode 202 is attached to the tip of the heating wire 210. The tip of the heat radiating tube 204 is sealed with a sealing material 206. For example, silicon is used as the sealing material. For example, magnesium oxide or the like is used as the insulating agent.

ヒータ用防湿キャップ100はヒータ200の放熱管204の外側に嵌めこまれ、電極202とヒータ用防湿キャップ100とは接触しない。ヒータ用防湿キャップ100が内部に強い吸湿作用を持つため、ヒータ200の吸湿を防止することができる。 The heater moisture-proof cap 100 is fitted outside the heat radiating tube 204 of the heater 200, and the electrode 202 and the heater moisture-proof cap 100 are not in contact with each other. Since the moisture-proof cap 100 for heater has a strong moisture-absorbing action inside, the moisture absorption of the heater 200 can be prevented.

本実施形態においては、ヒータ端部を封止材206により封止したものを用いているが、封止材206を有しないヒータに対しても本発明の防湿効果は発揮される。 In the present embodiment, the heater end portion sealed with the sealing material 206 is used. However, the moisture-proof effect of the present invention is exhibited even for a heater that does not have the sealing material 206.

対象ヒータは、外気と接することにより外気に含まれる水分を吸収し、その抵抗率が変化する性質がある。本発明のヒータ用防湿キャップ100は、対象ヒータの外気からの吸湿を防ぎ、袋状部材102と筒状部材108の開口部のネット状部材106とにより形成された空間に吸湿性を有する多孔質体104を有することにより、筒状部材108側の湿気を、ネット状部材106を通して多孔質体104に吸収する。 The target heater absorbs moisture contained in the outside air when in contact with the outside air, and has a property of changing its resistivity. The moisture-proof cap 100 for heaters of the present invention prevents moisture absorption from the outside air of the target heater, and has a porous property having moisture absorption in the space formed by the bag-like member 102 and the net-like member 106 at the opening of the cylindrical member 108. By having the body 104, moisture on the cylindrical member 108 side is absorbed by the porous body 104 through the net-like member 106.

本発明のヒータ用防湿キャップ100を対象ヒータ200に装着することによって、対象ヒータ200の吸湿を防ぐことができ、対象ヒータ200の絶縁抵抗値が低下することを防ぐことができる。また、吸湿により絶縁抵抗値が低下したヒータに対して本発明を用いることにより、絶縁抵抗値を回復させることができる。 By attaching the moisture-proof cap 100 for heaters of the present invention to the target heater 200, moisture absorption of the target heater 200 can be prevented, and a decrease in the insulation resistance value of the target heater 200 can be prevented. Further, by using the present invention for the heater whose insulation resistance value has decreased due to moisture absorption, the insulation resistance value can be recovered.

ヒータ用防湿キャップ100の筒状部材108に例えばシリコンを用いるとき、開口部が伸縮性を持つためヒータ200との密着性が高くなり、吸湿効果を向上することができる。 When, for example, silicon is used for the tubular member 108 of the moisture-proof cap 100 for the heater, the opening has elasticity, so that the adhesion with the heater 200 is increased, and the moisture absorption effect can be improved.

図3(A)は、本発明の一実施形態に係るヒータ用防湿キャップ350を示した図である。ヒータ用防湿キャップ350は筒状部材の内側にねじきり溝を設けている。ヒータ300は放熱管の外側にねじきり溝を設けたものを示している。図3(B)には、上記ヒータ用防湿キャップ350とヒータ300とを回転嵌合したものが示されている。
(Embodiment 2)
FIG. 3A is a view showing a moisture-proof cap 350 for a heater according to an embodiment of the present invention. The moisture-proof cap 350 for heaters has a threaded groove inside the cylindrical member. The heater 300 shows what provided the threaded groove in the outer side of the heat radiating tube. FIG. 3B shows the heater moisture-proof cap 350 and the heater 300 that are rotationally fitted.

図3(B)のような回転嵌合を用いることで、ヒータ用防湿キャップ350とヒータ300との密着性が増し、外れにくくなる。 By using the rotational fitting as shown in FIG. 3B, the adhesion between the moisture-proof cap 350 for the heater and the heater 300 is increased, and it is difficult to come off.

4A and 4B are cross-sectional views in which the moisture-proof cap for heaters according to one embodiment of the present invention is applied to the semiconductor heater unit 400. FIG. FIG. 4C is a perspective view of the semiconductor heater unit. The semiconductor heater unit 400 includes a heater 402 inside. The heater moisture-proof cap 410 of the present invention is attached to the tip of each electrode 408 of the heater, respectively, so that moisture absorption of the heater 402 can be suppressed.

また、半導体ヒータユニット400に本発明に係るヒータ用防湿キャップを用いる場合、図4(B)に示すようにヒータユニット400の終端部418に対して本発明に係るヒータ用防湿キャップ420を用いてもよい。ヒータユニット終端部418にヒータ用防湿キャップ420を用いることにより、ヒータの複数の電極に対して本発明に係るヒータ用防湿キャップ420を一部材のみを用いることができ、部品数の削減になる。 When the moisture barrier cap for heaters according to the present invention is used for the semiconductor heater unit 400, the moisture barrier cap for heaters 420 according to the present invention is used for the terminal portion 418 of the heater unit 400 as shown in FIG. Also good. By using the heater moisture-proof cap 420 for the heater unit terminal portion 418, only one member of the heater moisture-proof cap 420 according to the present invention can be used for a plurality of heater electrodes, and the number of parts can be reduced.
