ところが、前記アダプタは、円筒状の本体部がランプ部の端部を囲っているため、冷陰極蛍光ランプの発熱を効率よく放熱することが困難であった。もっとも、本体部の一部をカットし通気孔や切欠きを設けることにより、冷陰極蛍光ランプの熱を放熱することが可能になるが、本体部の形状が複雑になり、本体部の加工難度が向上し、コスト高になるという問題があった。 However, in the adapter, since the cylindrical main body portion surrounds the end portion of the lamp portion, it is difficult to efficiently dissipate the heat generated by the cold cathode fluorescent lamp. However, it is possible to dissipate the heat of the cold cathode fluorescent lamp by cutting a part of the main body and providing vents and notches, but the shape of the main body becomes complicated and the processing difficulty of the main body However, there was a problem that the cost was increased.

本発明は、上記事情に鑑みて創案されたものであって、その目的とするところは、電子部品から発せられる熱を効率よく放熱することができる安価なアダプタ及びこれに接続される接続装置を提供することにある。 The present invention was devised in view of the above circumstances, and an object thereof is to provide an inexpensive adapter capable of efficiently dissipating heat generated from an electronic component and a connection device connected thereto. It is to provide.

上記課題を解決するために、本発明のアダプタは、電子部品の本体部の長さ方向の端部に突設されたリード端子と、接続装置との間を接続可能なアダプタである。このアダプタは第１コイルと、前記第１コイルの回りに配置された第２コイルとを備えている。前記第１コイルは、前記リード端子に電気的に接続可能な第１接点部と、疎巻きにされたコイル状であって、前記本体部の端部が挿入可能な第１放熱部とを有している。前記第２コイルは、前記リード端子に電気的に接続可能な第２接点部と、前記第１放熱部が挿入されたコイル状の第２放熱部とを有している。前記第１、第２放熱部の少なくともいずれか一方が前記接続装置に電気的に接続可能になっている。 In order to solve the above-described problems, the adapter of the present invention is an adapter that can connect between a lead terminal projecting from an end portion in a length direction of a main body portion of an electronic component and a connection device. The adapter includes a first coil and a second coil disposed around the first coil . The first coil includes a first contact portion that can be electrically connected to the lead terminal, and a first heat radiating portion that is loosely coiled and into which an end of the main body portion can be inserted. doing. The second coil includes a second contact portion that can be electrically connected to the lead terminal, and a coil-shaped second heat radiating portion into which the first heat radiating portion is inserted. At least one of the first and second heat radiation portions can be electrically connected to the connection device.

このようなアダプタによる場合、第１放熱部がコイル状であるので、従来例の円筒状の本体部に比べて第１放熱部の空気に触れる表面積を大きくすることができる。このため、第１放熱部内に本体部の端部が挿入された状態で、該電子部品の本体部から発せられた熱が第１放熱部に伝わると、第１放熱部が空気に触れることにより、第１放熱部の熱を効率よく放熱することができる。この結果、電子部品の発熱を効率よく放熱することができる。また、本アダプタは、第１コイルの第１放熱部は線材をコイル状に巻くだけで簡単に作成することができるので、本アダプタの低コスト化を図ることができる。
また、疎巻きにされた第１放熱部のコイル間から熱が逃げやすくなるので、第１放熱部の放熱効率を更に向上させることができる。
更に、コイル状の第２放熱部が前記第１放熱部の回りに配置されているので、第２放熱部の分、空気に触れる表面積が大きくなる。このため、電子部品の発熱を更に効率よく放熱することができる。また、本アダプタは、２つのコイルを用いているため、導体断面積が一つのコイルを用いる場合に比べて増大する。よって、本アダプタの電気抵抗を低減することができ、本アダプタ自体の温度上昇を抑えることができる。また、本アダプタは、第１、第２コイルの第１、第２放熱部は線材をコイル状に巻くだけで簡単に作成することができるので、本アダプタの低コスト化を図ることができる。 In the case of such an adapter, since the first heat radiating portion is coiled, the surface area of the first heat radiating portion that comes into contact with air can be increased as compared with the cylindrical main body portion of the conventional example. For this reason, when the heat generated from the main body portion of the electronic component is transmitted to the first heat radiating portion with the end portion of the main body portion inserted into the first heat radiating portion, the first heat radiating portion touches the air. The heat of the first heat radiating portion can be efficiently radiated. As a result, the heat generated by the electronic component can be efficiently radiated. Moreover, since this adapter can be easily produced only by winding a wire in the shape of a coil, the 1st thermal radiation part of a 1st coil can achieve cost reduction of this adapter.
Moreover, since heat becomes easy to escape from between the coils of the first heat dissipating part that is loosely wound, the heat dissipating efficiency of the first heat dissipating part can be further improved.
Furthermore, since the coil-shaped second heat radiating portion is disposed around the first heat radiating portion, the surface area that comes into contact with air is increased by the amount of the second heat radiating portion. For this reason, the heat generated by the electronic component can be radiated more efficiently. Moreover, since this adapter uses two coils, the conductor cross-sectional area increases compared with the case where one coil is used. Therefore, the electrical resistance of this adapter can be reduced and the temperature rise of this adapter itself can be suppressed. In addition, since the first and second heat dissipating portions of the first and second coils of the adapter can be easily created simply by winding a wire in a coil shape, the cost of the adapter can be reduced.

前記第２放熱部が疎巻きにされていることが好ましい。このように前記第２放熱部が疎巻きにされていると、該第２放熱部のコイル間から熱が逃げやすくなるので、第２放熱部の放熱効率を更に向上させることができる。 It is preferable that the second heat radiating portion is loosely wound. When the second heat radiating portion is thus sparsely wound, heat can easily escape from between the coils of the second heat radiating portion, so that the heat radiating efficiency of the second heat radiating portion can be further improved.

前記第１、第２放熱部が疎巻きにされている場合、前記第１放熱部を構成する線材は、前記第２放熱部を構成する線材の間から外部に露出していることが好ましい。このように前記第１放熱部の線材が前記第２放熱部の線材の間から外部に露出していると、内側の第１放熱部が空気に触れやすくなるので、放熱効率を更に向上させることができる。 When the first and second heat radiating portions are sparsely wound, it is preferable that the wire constituting the first heat radiating portion is exposed to the outside from between the wires constituting the second heat radiating portion. As described above, when the wire of the first heat radiating portion is exposed to the outside from between the wires of the second heat radiating portion, the inner first heat radiating portion can easily come into contact with the air, so that the heat radiation efficiency is further improved. Can do.

前記第１接点部は前記第１放熱部に連続しており且つ前記リード端子が挿入され、接触可能な座巻部とすることができる。前記第２接点部は、前記第２放熱部に連続しており且つ前記第１接点部に外嵌し接触する座巻部とすることができる。この場合、第１コイルを第２コイル内に挿入し、第２接点部を第１接点部に外嵌させ接触させるだけで、第１コイルと第２コイルとを組み合わせることができる。よって、本アダプタの組み立てが簡単になるので、低コスト化を図ることができる。 The first contact portion is continuous with the first heat radiating portion, and the lead terminal is inserted into the end winding portion which can be contacted. The second contact portion may be an end winding portion that is continuous with the second heat radiating portion and that is externally fitted to and contacts the first contact portion. In this case, the first coil and the second coil can be combined simply by inserting the first coil into the second coil and fitting the second contact portion to the first contact portion so as to be in contact therewith. Therefore, the assembly of the adapter is simplified, and the cost can be reduced.

前記第１、第２放熱部は少なくとも一部が軸方向及び半径方向に弾性変形可能になっていると良い。この場合、前記第１、第２接点部が前記リード端子に電気的且つ機械的に接続され、前記第１、第２放熱部の少なくとも一方が前記接続装置に電気的且つ機械的に接続された状態で、電子部品が熱膨張又は熱収縮し、リード端子及び第１、第２接点部が熱膨張方向又は熱収縮方向に移動すると、前記第１、第２放熱部の少なくとも一部が前記軸方向及び／又は半径方向に弾性変形して電子部品の熱膨張又は熱収縮を吸収することができる。よって、電子部品の熱膨張又は熱収縮時に、リード端子及び本体部の端部のリード端子の根元部分にかかる負荷を低減することができる。 It is preferable that at least a part of the first and second heat radiating portions be elastically deformable in the axial direction and the radial direction. In this case, the first and second contact portions are electrically and mechanically connected to the lead terminal, and at least one of the first and second heat radiating portions is electrically and mechanically connected to the connection device. In this state, when the electronic component is thermally expanded or contracted and the lead terminal and the first and second contact portions are moved in the thermal expansion direction or the thermal contraction direction, at least a part of the first and second heat radiating portions is the shaft. The thermal expansion or contraction of the electronic component can be absorbed by elastic deformation in the direction and / or the radial direction. Therefore, it is possible to reduce the load applied to the lead terminal and the root portion of the lead terminal at the end of the main body when the electronic component is thermally expanded or contracted.

前記第１放熱部の内径が、前記本体部の端部が前記長さ方向に移動自在となる程度の大きさを有していることが好ましい。この場合、電子部品の熱膨張又は熱収縮時に、本体部の端部が前記第１放熱部内を移動するので、前記端部が前記第１放熱部内に引っ掛かる等して前記端部の移動が妨げられ、これにより前記リード端子及び本体部の端部のリード端子の根元部分に負荷がかかるのを防止することができる。 It is preferable that the inner diameter of the first heat radiating portion has such a size that an end portion of the main body portion is movable in the length direction. In this case, when the electronic component is thermally expanded or contracted, the end portion of the main body portion moves in the first heat radiating portion. Therefore, the end portion is prevented from moving by being caught in the first heat radiating portion. As a result, it is possible to prevent a load from being applied to the lead terminal and the root portion of the lead terminal at the end of the main body.

本発明の接続装置は、上記アダプタが接続される装置であって、前記アダプタの第１及び／又は第２放熱部が挿入可能な挿入凹部を有するボディと、前記ボディに設けられ且つ前記挿入凹部の内壁面に対向するコンタクトとを備えている。前記コンタクトと前記内壁面との間で前記第１及び／又は第２放熱部が弾性的に挟持されるようになっている。 The connection device of the present invention is a device to which the adapter is connected, and has a body having an insertion recess into which the first and / or second heat radiating portion of the adapter can be inserted, and the insertion recess provided in the body. And a contact facing the inner wall surface. The first and / or second heat radiating portion is elastically sandwiched between the contact and the inner wall surface.

前記接続装置がボディに設けられた一対のコンタクトを備えている場合、前記コンタクトと前記内壁面との間で前記第１及び／又は第２放熱部が弾性的に挟持されるのではなく、前記挿入凹部内において、前記一対のコンタクト間で前記第２放熱部が弾性的に挟持される構成とすることができる。 When the connection device includes a pair of contacts provided on the body, the first and / or second heat radiating portion is not elastically sandwiched between the contact and the inner wall surface, In the insertion recess, the second heat radiating portion can be elastically sandwiched between the pair of contacts.

前記ボディには、前記挿入凹部の壁面から前記ボディの外部にかけて貫通する通気孔が設けられていても良いし、前記挿入凹部の底面から前記ボディの外部にかけて貫通する通気孔が設けられていても良い。勿論、前記ボディに双方の通気孔が設けられていても良い。この場合、前記通気孔により前記挿入凹部に空気が流通しやすくなるので、前記アダプタの第１、第２放熱部に空気が触れ、該第１、第２放熱部の熱が効率よく放熱される。 The body may be provided with a vent hole penetrating from the wall surface of the insertion recess to the outside of the body, or may be provided with a vent hole penetrating from the bottom surface of the insertion recess to the outside of the body. good. Of course, both vent holes may be provided in the body. In this case, since the air easily flows through the insertion recess through the vent hole, the air touches the first and second heat radiating portions of the adapter, and the heat of the first and second heat radiating portions is efficiently radiated. .

以下、本発明の実施例１及び２について説明する。 Examples 1 and 2 of the present invention will be described below.

まず、本発明の実施例１のアダプタについて図１乃至図４を参照しつつ説明する。 First, the adapter according to the first embodiment of the present invention will be described with reference to FIGS.

図１乃至図３に示すアダプタ１００は、冷陰極蛍光ランプ１０のリード端子１１に接続されるものである。このアダプタ１００は、第１コイル１００ａと、この第１コイル１００ａが挿入され、第１コイル１００ａの回りに配置された第２コイル１００ｂとを備えている。以下、詳しく説明する。 The adapter 100 shown in FIGS. 1 to 3 is connected to the lead terminal 11 of the cold cathode fluorescent lamp 10. The adapter 100 includes a first coil 100a and a second coil 100b in which the first coil 100a is inserted and disposed around the first coil 100a. This will be described in detail below.

冷陰極蛍光ランプ１０は、図２乃至図４に示すように、リード端子１１と、円柱状のランプ部１２（本体部）とを備えている。リード端子１１はランプ部１２の長さ方向の両端部に突設されている。なお、図２乃至図４においては、冷陰極蛍光ランプ１０の長さ方向の一方のランプ部１２の端部及びリード端子１１のみが図示されている。また、図３では、ランプ部１２の内部構造が図示省略されている。 As shown in FIGS. 2 to 4, the cold cathode fluorescent lamp 10 includes a lead terminal 11 and a cylindrical lamp portion 12 (main body portion). The lead terminals 11 protrude from both end portions of the lamp portion 12 in the length direction. 2 to 4, only the end of one lamp portion 12 in the length direction of the cold cathode fluorescent lamp 10 and the lead terminal 11 are shown. In FIG. 3, the internal structure of the lamp unit 12 is not shown.

第１コイル１００ａは、図１乃至図４に示すように、導電性を有する断面円形の線材がコイル状に巻き回されたコイルスプリングである。この第１コイル１００ａは、第１接点部１１０ａと、第１放熱部１２０ａとを有している。第１接点部１１０ａは円筒状の座巻部であって、その内径がリード端子１１の外径よりも若干大きくなっている。第１放熱部１２０ａは、第１接点部１１０ａの後端に連続する円錐筒部１２１ａと、円錐筒部１２１ａの後端に連続する円筒部１２２ａとを有する疎巻き状のコイル部である。円筒部１２２ａは所定のコイル間隔をあけて巻かれている。円筒部１２２ａの内径は、ランプ部１２が挿入され、前記長さ方向に移動自在となる程度の大きさを有している。具体的には、円筒部１２２ａの内径はランプ部１２の外径よりも若干大きくなっている。円錐筒部１２１ａは、円筒部１２２ａよりも若干狭いコイル間隔で第１接点部１１０ａに向けて漸次低減するように巻かれている。円錐筒部１２１ａ及び円筒部１２２ａは、その軸方向及び半径方向に弾性変形可能になっている。すなわち、第１放熱部１２０ａ全体が軸方向及び半径方向に弾性変形可能になっている。 As shown in FIGS. 1 to 4, the first coil 100 a is a coil spring in which a conductive wire having a circular cross section is wound in a coil shape. The first coil 100a includes a first contact part 110a and a first heat radiating part 120a. The first contact portion 110 a is a cylindrical end winding portion, and the inner diameter thereof is slightly larger than the outer diameter of the lead terminal 11. The first heat radiating part 120a is a loosely wound coil part having a conical cylinder part 121a continuous to the rear end of the first contact part 110a and a cylindrical part 122a continuous to the rear end of the conical cylinder part 121a. The cylindrical portion 122a is wound with a predetermined coil interval. The inner diameter of the cylindrical portion 122a is large enough to allow the lamp portion 12 to be inserted and move in the length direction. Specifically, the inner diameter of the cylindrical portion 122 a is slightly larger than the outer diameter of the lamp portion 12. The conical cylinder part 121a is wound so as to gradually decrease toward the first contact part 110a with a slightly smaller coil interval than the cylindrical part 122a. The conical cylinder portion 121a and the cylindrical portion 122a are elastically deformable in the axial direction and the radial direction. That is, the entire first heat radiating portion 120a can be elastically deformed in the axial direction and the radial direction.

第２コイル１００ｂは、図２乃至図４に示すように、導電性を有する断面円形の線材がコイル状に巻き回されたコイルスプリングである。この第２コイル１００ｂは、第２接点部１１０ｂと、第２放熱部１２０ｂとを有している。第２接点部１１０ｂは、円筒状の座巻部であって、先端部と、後端部とを有している。前記先端部の内径は、第１コイル１００ａの第１接点部１１０ａの内径と同じであり、前記後端部の内径は第１コイル１００ａの第１接点部１１０ａの外径と略同じになっている。この第２接点部１１０ｂの後端部が第１接点部１１０ａに外嵌し接触している。これにより、第１コイル１００ａが第２コイル１００ｂ内に挿入された状態で組み合わされている。第２接点部１１０ｂの先端部及び第１接点部１１０ａ内には、リード端子１１が挿入され、接触可能となっている。第２放熱部１２０ｂは、第２接点部１１０ｂの後端に連続する円錐筒部１２１ｂと、円錐筒部１２１ｂの後端に連続する円筒部１２２ｂとを有する疎巻き状のコイル部である。円錐筒部１２１ｂは、円錐筒部１２１ａよりも広いコイル間隔で第２接点部１１０ｂに向けて外径が漸次低減するように巻かれている。円筒部１２２ｂは円筒部１２２ａと略同じコイル間隔をあけて巻かれている。円筒部１２２ｂの内径は円筒部１２２ａの外径よりも若干大きくなっている。この円筒部１２２ｂ内に円筒部１２２ａが挿入されている。また、円筒部１２２ｂの長さ寸法は円筒部１２２ａよりも長さ寸法よりも小さくなっている。このため、円筒部１２２ａの後端部が円筒部１２２ｂから後方に突出している。また、第２接点部１１０ｂの長さ寸法、円錐筒部１２１ｂの長さ寸法及び／又は円錐筒部１２１ｂのコイル間隔が、円筒部１２２ｂを構成する線材の間から円筒部１２２ａを構成する線材が外部に露出するように調整されている。これにより、円筒部１２２ａ、１２２ｂの双方が外気に触れやすくなっている。円錐筒部１２１ｂ及び円筒部１２２ｂはその軸方向及び半径方向に弾性変形可能になっている。すなわち、第２放熱部１２０ｂ全体が軸方向及び半径方向に弾性変形可能になっている。 As shown in FIGS. 2 to 4, the second coil 100 b is a coil spring in which a conductive wire having a circular cross section is wound in a coil shape. The second coil 100b includes a second contact part 110b and a second heat radiating part 120b. The 2nd contact part 110b is a cylindrical end winding part, Comprising: It has a front-end | tip part and a rear-end part. The inner diameter of the front end portion is the same as the inner diameter of the first contact portion 110a of the first coil 100a, and the inner diameter of the rear end portion is substantially the same as the outer diameter of the first contact portion 110a of the first coil 100a. Yes. The rear end portion of the second contact portion 110b is externally fitted and in contact with the first contact portion 110a. Thereby, the 1st coil 100a is combined in the state inserted in the 2nd coil 100b. The lead terminal 11 is inserted into the distal end portion of the second contact portion 110b and the first contact portion 110a so as to be contactable. The second heat dissipating part 120b is a loosely wound coil part having a conical cylinder part 121b continuous to the rear end of the second contact part 110b and a cylindrical part 122b continuous to the rear end of the conical cylinder part 121b. The conical cylinder part 121b is wound so that the outer diameter gradually decreases toward the second contact part 110b with a wider coil interval than the conical cylinder part 121a. The cylindrical portion 122b is wound with substantially the same coil interval as the cylindrical portion 122a. The inner diameter of the cylindrical portion 122b is slightly larger than the outer diameter of the cylindrical portion 122a. A cylindrical portion 122a is inserted into the cylindrical portion 122b. The length of the cylindrical portion 122b is smaller than the length of the cylindrical portion 122a. For this reason, the rear-end part of the cylindrical part 122a protrudes back from the cylindrical part 122b. Further, the length of the second contact part 110b, the length of the conical cylinder part 121b, and / or the coil interval of the conical cylinder part 121b is such that the wire constituting the cylindrical part 122a is between the wires constituting the cylindrical part 122b. It is adjusted to be exposed to the outside. Thereby, both cylindrical parts 122a and 122b are easy to touch outside air. The conical cylinder portion 121b and the cylindrical portion 122b are elastically deformable in the axial direction and the radial direction. That is, the entire second heat radiating portion 120b can be elastically deformed in the axial direction and the radial direction.

以下、上述した構成のアダプタ１００の製造方法について説明する。まず、上記線材を巻き回して第１コイル１００ａを作成し、上記線材を巻き回して第２コイル１００ｂを作成する。その後、図３に示すように、第１コイル１００ａの第１接点部１１０ａを第２コイル１００ｂの後方から第２放熱部１２０ｂ内に挿入する。その後、第１コイル１００ａの第１接点部１１０ａを第２放熱部１２０ｂ内で前進させ、第２接点部１１０ｂの後端部に嵌合させる。このとき、第１コイル１００ａの第１放熱部１２０ａが第２コイル１００ｂの第２放熱部１２０ｂ内に挿入され、第１放熱部１２０ａの円筒部１２２ａの線材が第２放熱部１２０ｂの円筒部１２２ｂの線材の間から外部に露出するように配置される。このようにして第１、第２コイル１００ａ、１００ｂが組み合わされ、アダプタ１００となる。 Hereinafter, a method for manufacturing the adapter 100 having the above-described configuration will be described. First, the said wire is wound and the 1st coil 100a is created, and the said wire is wound and the 2nd coil 100b is created. Thereafter, as shown in FIG. 3, the first contact part 110a of the first coil 100a is inserted into the second heat radiation part 120b from the rear of the second coil 100b. Thereafter, the first contact part 110a of the first coil 100a is advanced in the second heat radiation part 120b and fitted to the rear end part of the second contact part 110b. At this time, the first heat radiating portion 120a of the first coil 100a is inserted into the second heat radiating portion 120b of the second coil 100b, and the wire rod of the cylindrical portion 122a of the first heat radiating portion 120a is the cylindrical portion 122b of the second heat radiating portion 120b. It arrange | positions so that it may be exposed outside from between the wires. In this way, the first and second coils 100 a and 100 b are combined to form the adapter 100.

以下、アダプタ１００に冷陰極蛍光ランプ１０を接続する手順について説明する。まず、冷陰極蛍光ランプ１０のリード端子１１をアダプタ１００の後方からアダプタ１００の第１コイル１００ａの第１放熱部１２０ａ内に挿入する。その後、リード端子１１を第１放熱部１２０ａ内で前進させ、第１接点部１１０ａ及び第２接点部１１０ｂの先端部内に挿入する。すると、リード端子１１が第１接点部１１０ａ及び第２接点部１１０ｂの先端部に接触し、ランプ部１２の端部が第１放熱部１２０ａ内に挿入される。その後、リード端子１１を第２接点部１１０ｂの先端部に半田又は溶接により電気的且つ機械的に接続する。 Hereinafter, a procedure for connecting the cold cathode fluorescent lamp 10 to the adapter 100 will be described. First, the lead terminal 11 of the cold cathode fluorescent lamp 10 is inserted into the first heat radiation part 120 a of the first coil 100 a of the adapter 100 from the rear of the adapter 100. Thereafter, the lead terminal 11 is advanced in the first heat radiating portion 120a and inserted into the tip portions of the first contact portion 110a and the second contact portion 110b. Then, the lead terminal 11 comes into contact with the distal end portions of the first contact portion 110a and the second contact portion 110b, and the end portion of the lamp portion 12 is inserted into the first heat radiation portion 120a. Thereafter, the lead terminal 11 is electrically and mechanically connected to the tip of the second contact part 110b by soldering or welding.

なお、上述の如く組み合わされた第１、第２コイル１００ａ、１００ｂを冷陰極蛍光ランプ１０に接続するのではなく、冷陰極蛍光ランプ１０に第１、第２コイル１００ａ、１００ｂを順次接続するようにしても構わない。具体的には、冷陰極蛍光ランプ１０のリード端子１１を第１コイル１００ａに後方から挿入し、リード端子１１を第１接点部１１０ａに挿入して接触させると共に、ランプ部１２の端部を第１放熱部１２０ａ内に挿入させる。その後、冷陰極蛍光ランプ１０及び第１コイル１００ａを第２コイル１００ｂに後方から挿入し、リード端子１１を第２コイル１００ｂの第２接点部１１０ｂの先端部内に挿入すると共に、第１コイル１００ａの第１接点部１１０ａを第２接点部１１０ｂの後端部に嵌合させる。このとき、第１コイル１００ａの第１放熱部１２０ａが第２コイル１００ｂの第２放熱部１２０ｂ内に挿入され、第１放熱部１２０ａの円筒部１２２ａの線材が第２放熱部１２０ｂの円筒部１２２ｂの線材の間から外部に露出するように配置される。 The first and second coils 100a and 100b combined as described above are not connected to the cold cathode fluorescent lamp 10, but the first and second coils 100a and 100b are sequentially connected to the cold cathode fluorescent lamp 10. It doesn't matter. Specifically, the lead terminal 11 of the cold cathode fluorescent lamp 10 is inserted into the first coil 100a from behind, the lead terminal 11 is inserted into and contacted with the first contact part 110a, and the end of the lamp part 12 is connected to the first coil part 100a. 1 Insert into the heat dissipating part 120a. Thereafter, the cold cathode fluorescent lamp 10 and the first coil 100a are inserted into the second coil 100b from the rear, the lead terminal 11 is inserted into the tip of the second contact part 110b of the second coil 100b, and the first coil 100a The first contact part 110a is fitted to the rear end part of the second contact part 110b. At this time, the first heat radiating portion 120a of the first coil 100a is inserted into the second heat radiating portion 120b of the second coil 100b, and the wire rod of the cylindrical portion 122a of the first heat radiating portion 120a is the cylindrical portion 122b of the second heat radiating portion 120b. It arrange | positions so that it may be exposed outside from between the wires.

以下、アダプタ１００が冷陰極蛍光ランプ１０と共に接続される接続装置２００について図５及び図６を参照しつつ説明する。図５に示す接続装置２００は、ボディ２１０と、コンタクト２２０とを備えている。以下、各部について詳しく説明する。 Hereinafter, the connection device 200 to which the adapter 100 is connected together with the cold cathode fluorescent lamp 10 will be described with reference to FIGS. 5 and 6. A connecting device 200 shown in FIG. 5 includes a body 210 and a contact 220. Hereinafter, each part will be described in detail.

ボディ２１０は略立方体の絶縁樹脂製の射出成形品である。このボディ２１０には、図５及び図６に示すように、該ボディ２１０を厚み方向に貫通した断面略Ｕ字状の挿入凹部２１１が設けられている。この挿入凹部２１１にアダプタ１００が挿脱自在となっている。ボディ２１０の挿入凹部２１１の長さ方向の両壁部が第１、第２壁部２１２、２１３となっている。ボディ２１０の挿入凹部２１１の底板の第１壁部２１２の近傍には矩形状の開口２１１ａが、該底板の中央部には矩形状の通気孔２１１ｂが設けられている。また、ボディ２１０には、開口２１１ａに連通しており且つ下側に開放された取付孔２１４が設けられている。この取付孔２１４の幅寸法は、コンタクト２２０の本体部の幅寸法よりも若干小さくなっている。すなわち、取付孔２１４にコンタクト２２０の本体部が圧入され取り付けられるようになっている。通気孔２１１ｂは、ボディ２１０の底板を厚み方向に貫通し、該ボディ２１０の外部に通じている。第１壁部２１２は、中央壁と、中央壁の前記厚み方向の両端に第２壁部２１３に向けて立設された一対の側壁とを有している。第１壁部２１２の中央壁には、該中央壁の内壁面から外壁面にかけて貫通する一対の通気孔２１２ａが設けられている。第２の壁部２１３は第１壁部２１２よりも厚い壁であって、内壁面から外壁面にかけて貫通する一対の通気孔２１３ａが設けられている。また、ボディ２１０の下面の角部には、一対の係止凸部２１５が設けられている。この係止凸部２１５が基板２０の図示しない係止孔に係止されるようになっている。 The body 210 is an injection molded product made of a substantially cubic insulating resin. As shown in FIGS. 5 and 6, the body 210 is provided with an insertion recess 211 having a substantially U-shaped cross section that penetrates the body 210 in the thickness direction. The adapter 100 can be inserted into and removed from the insertion recess 211. Both wall portions in the length direction of the insertion concave portion 211 of the body 210 are first and second wall portions 212 and 213. A rectangular opening 211a is provided in the vicinity of the first wall portion 212 of the bottom plate of the insertion recess 211 of the body 210, and a rectangular vent hole 211b is provided in the center of the bottom plate. In addition, the body 210 is provided with a mounting hole 214 that communicates with the opening 211a and that opens downward. The width dimension of the mounting hole 214 is slightly smaller than the width dimension of the main body portion of the contact 220. That is, the main body of the contact 220 is press-fitted into the attachment hole 214 and attached. The vent hole 211b passes through the bottom plate of the body 210 in the thickness direction and communicates with the outside of the body 210. The first wall portion 212 includes a central wall and a pair of side walls erected toward the second wall portion 213 at both ends of the central wall in the thickness direction. The central wall of the first wall portion 212 is provided with a pair of vent holes 212a penetrating from the inner wall surface to the outer wall surface of the central wall. The second wall portion 213 is thicker than the first wall portion 212, and is provided with a pair of vent holes 213a penetrating from the inner wall surface to the outer wall surface. A pair of locking projections 215 are provided at the corners of the lower surface of the body 210. This locking projection 215 is locked in a locking hole (not shown) of the substrate 20.

コンタクト２２０は導電性を有する板がプレス成形されたものである。このコンタクト２２０は、図５（ａ）及び図５（ｃ）に示すように、図示しない前記本体部と、接点部２２１と、接続部２２２とを有している。コンタクト２２０の本体部は略矩形状の板部であって、ボディ２１０の取付孔２１４に圧入され、取り付けられている。接点部２２１は、前記本体部の上端に連続して設けられた板部であって、ボディ２１０の開口２１１ａから挿入凹部２１１内に挿入されている。この接点部２２１は、第２壁部２１３の内壁面に向けて略Ｕ字状に折り曲げられており、該第２壁部２１３の内壁面から離れる方向に弾性変形可能になっている。接点部２２１と第２壁部２１３の内壁面とは、互いに対向しており、その間の距離はアダプタ１００の第２放熱部１２０ｂの円筒部１２２ｂの直径よりも小さくなっている。すなわち、接点部２２１と第２壁部２１３の内壁面との間にアダプタ１００の円筒部１２２ｂが挿入されることにより、接点部２２１と第２壁部２１３の内壁面との間でアダプタ１００の円筒部１２２ｂが挟持されるようになっている。接続部２２２は二股状になっており、基板２０の図示しない接続孔に係止され且つ電気的に接続されるようになっている。 The contact 220 is obtained by press-molding a conductive plate. As shown in FIGS. 5A and 5C, the contact 220 has the body portion (not shown), a contact portion 221, and a connection portion 222. The body portion of the contact 220 is a substantially rectangular plate portion, and is press-fitted into the attachment hole 214 of the body 210 and attached. The contact portion 221 is a plate portion provided continuously at the upper end of the main body portion, and is inserted into the insertion recess 211 from the opening 211 a of the body 210. The contact portion 221 is bent in a substantially U shape toward the inner wall surface of the second wall portion 213, and can be elastically deformed in a direction away from the inner wall surface of the second wall portion 213. The contact portion 221 and the inner wall surface of the second wall portion 213 are opposed to each other, and the distance therebetween is smaller than the diameter of the cylindrical portion 122b of the second heat radiating portion 120b of the adapter 100. That is, when the cylindrical portion 122b of the adapter 100 is inserted between the contact portion 221 and the inner wall surface of the second wall portion 213, the adapter 100 is interposed between the contact portion 221 and the inner wall surface of the second wall portion 213. The cylindrical part 122b is clamped. The connecting portion 222 has a bifurcated shape, is locked in a connection hole (not shown) of the substrate 20 and is electrically connected.

以下、上述した構成の接続装置２００にアダプタ１００を接続する手順について説明する。まず、上述の如く冷陰極蛍光ランプ１０が接続されたアダプタ１００の円筒部１２２ｂを接続装置２００のコンタクト２２０の接点部２２１と第２壁部２１３の内壁面との間に挿入する。すると、接点部２２１が第２壁部２１３の内壁面から離れる方向に弾性変形する。その後、円筒部１２２ｂが接点部２２１の折り曲げ部の頂部を乗り越えると、接点部２２１が自身の弾性力により、第２壁部２１３の内壁面に近づく方向に復帰移動する。これにより、円筒部１２２ｂが接点部２２１と第２壁部２１３の内壁面との間で挟持される。このようにしてアダプタ１００の円筒部１２２ｂが接続装置２００に電気的且つ機械的に接続される。以下、この状態を第１接続状態と称する。 Hereinafter, a procedure for connecting the adapter 100 to the connection device 200 having the above-described configuration will be described. First, the cylindrical portion 122b of the adapter 100 to which the cold cathode fluorescent lamp 10 is connected as described above is inserted between the contact portion 221 of the contact 220 of the connection device 200 and the inner wall surface of the second wall portion 213. Then, the contact part 221 is elastically deformed in a direction away from the inner wall surface of the second wall part 213. Thereafter, when the cylindrical portion 122b gets over the top of the bent portion of the contact portion 221, the contact portion 221 moves back in a direction approaching the inner wall surface of the second wall portion 213 by its own elastic force. Accordingly, the cylindrical portion 122b is sandwiched between the contact portion 221 and the inner wall surface of the second wall portion 213. In this way, the cylindrical portion 122b of the adapter 100 is electrically and mechanically connected to the connection device 200. Hereinafter, this state is referred to as a first connection state.

この第１接続状態で、冷陰極蛍光ランプ１０のリード端子１１が基板２０、コンタクト２２０及びアダプタ１００を通じて通電され、該ランプ部１２が発熱すると、その熱がランプ部１２の端部を囲うアダプタ１００の第１、第２放熱部１２０ａ、１２０ｂに伝わる。この第１、第２放熱部１２０ａ、１２０ｂは、断面円形の線材が間隔をあけて巻かれたコイル部であって、第１放熱部１２０ａの円筒部１２２ａを構成する線材が第２放熱部１２０ｂの円筒部１２２ｂを構成する線材の間から外部に露出している。すなわち、第１、第２放熱部１２０ａ、１２０ｂは空気に触れる表面積が大きく且つ円筒部１２２ａ、１２２ｂの双方が空気に触れやすくなっているので、第１、第２放熱部１２０ａ、１２０ｂが空気に触れることにより、第１、第２放熱部１２０ａ、１２０ｂの熱を効率よく放熱することができる。この結果、冷陰極蛍光ランプ１０のランプ部１２の発熱も効率よく放熱することができる。しかも、接続装置２００は、ボディ２１０に通気孔２１１ｂ、２１２ａ、２１３ａが設けられているので、通気孔２１１ｂ、２１２ａ、２１３ａを通じてボディ２１０の挿入凹部２１１に空気を流通させることが可能になり、その結果、該ボディ２１０の挿入凹部２１１に挿入されたアダプタ１００及びランプ部１２の端部の熱を効率よく逃がすことができる。また、アダプタ１００は、２つのコイルを用いているため、導体断面積を一つのコイルを用いた場合に比べて増大させることができる。よって、アダプタ１００の電気抵抗を低減することができ、アダプタ１００自体の温度上昇を抑えることができる。 In this first connection state, the lead terminal 11 of the cold cathode fluorescent lamp 10 is energized through the substrate 20, the contact 220 and the adapter 100, and when the lamp unit 12 generates heat, the heat encloses the end of the lamp unit 12. To the first and second heat radiating portions 120a and 120b. The first and second heat radiating portions 120a and 120b are coil portions in which a wire having a circular cross section is wound at an interval, and the wire constituting the cylindrical portion 122a of the first heat radiating portion 120a is the second heat radiating portion 120b. It is exposed to the outside from between the wires constituting the cylindrical portion 122b. That is, since the first and second heat radiating portions 120a and 120b have a large surface area in contact with air and both the cylindrical portions 122a and 122b are easy to touch air, the first and second heat radiating portions 120a and 120b are exposed to air. By touching, the heat of the first and second heat radiating portions 120a and 120b can be efficiently radiated. As a result, the heat generated by the lamp portion 12 of the cold cathode fluorescent lamp 10 can also be radiated efficiently. Moreover, since the connection device 200 is provided with the vent holes 211b, 212a, and 213a in the body 210, air can be circulated to the insertion recess 211 of the body 210 through the vent holes 211b, 212a, and 213a. As a result, the heat at the ends of the adapter 100 and the lamp portion 12 inserted into the insertion recess 211 of the body 210 can be efficiently released. Moreover, since the adapter 100 uses two coils, the conductor cross-sectional area can be increased as compared with the case where one coil is used. Therefore, the electrical resistance of the adapter 100 can be reduced, and the temperature rise of the adapter 100 itself can be suppressed.

また、アダプタ１００は、線材をコイル状に巻いて第１、第２コイル１００ａ、１００ｂを作成し、第１コイル１００ａを第２コイル１００ｂ内に挿入するだけで、簡単に製造することができるので、従来例の如く複雑な加工を必要としない。よって、アダプタ１００の低コスト化を図ることができる。 In addition, the adapter 100 can be easily manufactured simply by winding the wire in a coil shape to create the first and second coils 100a and 100b and inserting the first coil 100a into the second coil 100b. Thus, complicated processing is not required as in the conventional example. Therefore, cost reduction of the adapter 100 can be achieved.

また、アダプタ１００の第１、第２放熱部１２０ａ、１２０ｂが軸方向及び半径方向に弾性変形可能となっているので、前記第１接続状態で、冷陰極蛍光ランプ１０が自身の発熱や外気温の上昇等の外部環境の変化により熱膨張、又は外気温の低下等の外部環境の変化により熱収縮し、リード端子１１及びこれに接続されたアダプタ１００の第１、第２接点部１１０ａ、１１０ｂが熱膨張方向又は熱収縮方向に移動したとしても、第１、第２放熱部１２０ａ、１２０ｂの接続装置２００の接点部２２１とボディ２１０の第２壁部２１３の内壁面との間との間で挟持された部分の前方部分（すなわち、第１、第２放熱部１２０ａ、１２０ｂの前記挟持された部分より第１、第２接点部１１０ａ、１１０ｂ側の部分）が熱膨張方向又は熱収縮方向に（すなわち、軸方向及び／又は半径方向に）弾性変形し、冷陰極蛍光ランプ１０の熱膨張又は熱収縮を吸収することができる。よって、冷陰極蛍光ランプ１０の熱膨張又は熱収縮時に、リード端子１１及びランプ部１２のリード端子１１の根元部分にかかる負荷を低減することができる。また、第１放熱部１２０ａの円筒部１２２ａの内径が、ランプ部１２の端部が前記長さ方向に移動自在となる程度の大きさを有していることから、冷陰極蛍光ランプ１０の熱膨張又は熱収縮時に、前記端部が円筒部１２２ａ内で引っ掛かる等して前記端部の移動が妨げられ、これによりリード端子１１及びランプ部１２のリード端子１１の根元部分に負荷がかかるのを防止することもできる。 In addition, since the first and second heat radiating portions 120a and 120b of the adapter 100 can be elastically deformed in the axial direction and the radial direction, the cold cathode fluorescent lamp 10 generates heat and air temperature in the first connection state. The first and second contact portions 110a and 110b of the lead terminal 11 and the adapter 100 connected thereto are thermally expanded due to a change in the external environment such as a rise in temperature, or a thermal contraction due to a change in the external environment such as a decrease in outside air temperature. Between the contact portion 221 of the connection device 200 of the first and second heat radiating portions 120a and 120b and the inner wall surface of the second wall portion 213 of the body 210 even if the heat is moved in the thermal expansion direction or the thermal contraction direction. The front portion of the portion sandwiched between the first and second heat radiating portions 120a and 120b (the portion closer to the first and second contact portions 110a and 110b than the sandwiched portion) is in the direction of thermal expansion or contraction. (I.e., in the axial direction and / or radial) elastically deformed can absorb thermal expansion or thermal contraction of the cold cathode fluorescent lamp 10. Therefore, when the cold cathode fluorescent lamp 10 is thermally expanded or contracted, the load applied to the lead terminal 11 and the root portion of the lead terminal 11 of the lamp portion 12 can be reduced. Further, since the inner diameter of the cylindrical portion 122a of the first heat radiating portion 120a has such a size that the end portion of the lamp portion 12 is movable in the length direction, the heat of the cold cathode fluorescent lamp 10 is increased. At the time of expansion or thermal contraction, the end portion is caught in the cylindrical portion 122a and the movement of the end portion is hindered, thereby applying a load to the root portion of the lead terminal 11 and the lead terminal 11 of the lamp portion 12. It can also be prevented.

次に、本発明の実施例２のアダプタについて図７乃至図１０を参照しつつ説明する。図７乃至図１０に示すアダプタ３００は、冷陰極蛍光ランプ１０のリード端子１１に接続されるものである。このアダプタ３００は、第１、第２コイル３００ａ、３００ｂを備えている。 Next, an adapter according to a second embodiment of the present invention will be described with reference to FIGS.

It is the cylindrical coil part wound by the double helix shape so that it may line up alternately. The first and second contact portions 310a and 310b are loosely wound at a predetermined coil interval. The inner diameters of the first and second contact portions 310 a and 310 b are slightly larger than the outer diameter of the lead terminal 11. The lead terminal 11 is inserted into the first and second contact portions 310a and 310b so as to come into contact with the first and second contact portions 310a and 310b.

第１、第２放熱部３２０ａ、３２０ｂは、前記二本の線材の後端部（すなわち、前記二本の線材のうち第１、第２放熱部３２０ａ、３２０ｂを構成する部分）が前記長さ方向に交互に並ぶように二重螺旋状に巻き回された筒状のコイル部である。第１、第２放熱部３２０ａ、３２０ｂは、第１、第２接点部３１０ａ、３１０ｂの後端に連続する円錐筒部３２１ａ、３２１ｂと、円錐筒部３２１ａ、３２１ｂの後端に連続する円筒部３２２ａ、３２２ｂとを有している。円筒部３２２ａ、３２２ｂは所定のコイル間隔で疎巻きにされている。円筒部３２２ａ、３２２ｂの内径は、ランプ部１２が挿入され、前記長さ方向に移動自在となる程度の大きさを有している。具体的には、円筒部３２２ａ、３２２ｂの内径はランプ部１２の外径よりも若干大きくなっている。円錐筒部３２１ａ、３２１ｂは第１、第２接点部３１０ａ、３１０ｂに向けて外径が漸次低減するように巻かれている。この円錐筒部３２１ａ、３２１ｂは円筒部３２２ａ、３２２ｂよりも広いコイル間隔で疎巻きにされている。円錐筒部３２１ａ、３２１ｂ及び円筒部３２２ａ、３２２ｂは、その軸方向及び半径方向に弾性変形可能になっている。すなわち、第１、第２放熱部３２０ａ、３２０ｂ全体が軸方向及び半径方向に弾性変形可能になっている。 The first and second heat radiating portions 320a and 320b have the lengths of the rear ends of the two wire rods (that is, the portions constituting the first and second heat radiating portions 320a and 320b of the two wire rods). It is the cylindrical coil part wound by the double helix shape so that it may be located in a line by turns. The first and second heat radiating portions 320a and 320b include conical cylindrical portions 321a and 321b that are continuous to the rear ends of the first and second contact portions 310a and 310b, and cylindrical portions that are continuous to the rear ends of the conical cylindrical portions 321a and 321b. 322a and 322b. The cylindrical portions 322a and 322b are loosely wound at a predetermined coil interval. The inner diameters of the cylindrical portions 322a and 322b are large enough to allow the lamp portion 12 to be inserted and move in the length direction. Specifically, the inner diameters of the cylindrical portions 322 a and 322 b are slightly larger than the outer diameter of the lamp portion 12. The conical cylinder portions 321a and 321b are wound so that the outer diameter gradually decreases toward the first and second contact portions 310a and 310b. The conical cylinder portions 321a and 321b are loosely wound with a wider coil interval than the cylindrical portions 322a and 322b. The conical cylinder portions 321a and 321b and the cylindrical portions 322a and 322b are elastically deformable in the axial direction and the radial direction. That is, the entire first and second heat radiating portions 320a and 320b can be elastically deformed in the axial direction and the radial direction.

上述した構成のアダプタ３００は、上記二本の線材を平行に配置し、互いに接触させる。この状態で前記線材を、該線材が冷陰極蛍光ランプ１０の長さ方向に交互に並ぶように二重螺旋状に巻き回す。これにより、アダプタ３００が製造される。 The adapter 300 having the above-described configuration arranges the two wires in parallel and brings them into contact with each other. In this state, the wire is wound in a double spiral so that the wire is alternately arranged in the length direction of the cold cathode fluorescent lamp 10. Thereby, the adapter 300 is manufactured.

以下、アダプタ３００に冷陰極蛍光ランプ１０を接続する手順について説明する。まず、図８に示すように、冷陰極蛍光ランプ１０のリード端子１１をアダプタ３００の後方から第１、第２放熱部３２０ａ、３２０ｂ内に挿入する。その後、リード端子１１を第１、第２放熱部３２０ａ、３２０ｂ内で前進させ、第１、第２接点部３１０ａ、３１０ｂに挿入する。すると、リード端子１１が第１、第２接点部３１０ａ、３１０ｂに接触し、ランプ部１２の端部が第１、第２放熱部３２０ａ、３２０ｂ内に挿入される。その後、リード端子１１を第１、第２接点部３１０ａ、３１０ｂに半田又は溶接により電気的且つ機械的に接続する。 Hereinafter, a procedure for connecting the cold cathode fluorescent lamp 10 to the adapter 300 will be described. First, as shown in FIG. 8, the lead terminal 11 of the cold cathode fluorescent lamp 10 is inserted into the first and second heat radiation portions 320 a and 320 b from the rear of the adapter 300. Thereafter, the lead terminal 11 is advanced in the first and second heat radiating portions 320a and 320b and inserted into the first and second contact portions 310a and 310b. Then, the lead terminal 11 contacts the first and second contact portions 310a and 310b, and the end portion of the lamp portion 12 is inserted into the first and second heat radiating portions 320a and 320b. Thereafter, the lead terminal 11 is electrically and mechanically connected to the first and second contact portions 310a and 310b by soldering or welding.

その後、アダプタ３００を上記接続装置２００に次の通り接続する。まず、アダプタ３００の第１、第２放熱部３２０ａ、３２０ｂの円筒部３２２ａ、３２２ｂを接続装置２００のコンタクト２２０の接点部２２１と第２壁部２１３の内壁面との間に挿入する。すると、接点部２２１が第２壁部２１３の内壁面から離れる方向に弾性変形する。その後、円筒部３２２ａ、３２２ｂが接点部２２１の折り曲げ部の頂部を乗り越えると、接点部２２１が自身の弾性力により、第２壁部２１３の内壁面に近づく方向に復帰移動する。これにより、円筒部３２２ａ、３２２ｂが接点部２２１と第２壁部２１３の内壁面との間で挟持される。このようにしてアダプタ３００の第１、第２放熱部３２０ａ、３２０ｂの円筒部３２２ａ、３２２ｂが接続装置２００に電気的且つ機械的に接続される。以下、この状態を第２接続状態と称する。 Thereafter, the adapter 300 is connected to the connection device 200 as follows. First, the cylindrical portions 322 a and 322 b of the first and second heat radiating portions 320 a and 320 b of the adapter 300 are inserted between the contact portion 221 of the contact 220 of the connection device 200 and the inner wall surface of the second wall portion 213. Then, the contact part 221 is elastically deformed in a direction away from the inner wall surface of the second wall part 213. Thereafter, when the cylindrical portions 322a and 322b get over the top of the bent portion of the contact portion 221, the contact portion 221 returns and moves in a direction approaching the inner wall surface of the second wall portion 213 by its own elastic force. Accordingly, the cylindrical portions 322a and 322b are sandwiched between the contact portion 221 and the inner wall surface of the second wall portion 213. In this manner, the cylindrical portions 322a and 322b of the first and second heat radiating portions 320a and 320b of the adapter 300 are electrically and mechanically connected to the connection device 200. Hereinafter, this state is referred to as a second connection state.

この第２接続状態で、冷陰極蛍光ランプ１０のリード端子１１が基板２０、コンタクト２２０及びアダプタ３００を通じて通電され、ランプ部１２が発熱すると、その熱がランプ部１２の端部を囲うアダプタ３００の第１、第２放熱部３２０ａ、３２０ｂに伝わる。この第１、第２放熱部３２０ａ、３２０ｂは、断面円形の線材が間隔をあけて長さ方向に交互に並ぶように二重螺旋状に巻かれたコイル部である。すなわち、第１、第２放熱部１２０ａ、１２０ｂは空気に触れる表面積が大きくなっているので、第１、第２放熱部１２０ａ、１２０ｂが空気に触れることにより、第１、第２放熱部１２０ａ、１２０ｂの熱を効率よく放熱することができる。この結果、冷陰極蛍光ランプ１０のランプ部１２の発熱も効率よく放熱することができる。しかも、接続装置２００は、ボディ２１０に通気孔２１１ｂ、２１２ａ、２１３ａが設けられているので、通気孔２１１ｂ、２１２ａ、２１３ａを通じてボディ２１０の挿入凹部２１１に空気を流通させることが可能になり、その結果、該ボディ２１０の挿入凹部２１１に挿入されたアダプタ３００及びランプ部１２の端部の熱を効率よく逃がすことができる。また、アダプタ３００は、２つのコイルを用いているため、導体断面積を一つのコイルを用いた場合に比べて増大させることができる。よって、アダプタ３００の電気抵抗を低減することができ、アダプタ３００自体の温度上昇を抑えることができる。 In this second connection state, when the lead terminal 11 of the cold cathode fluorescent lamp 10 is energized through the substrate 20, the contact 220 and the adapter 300 and the lamp unit 12 generates heat, the heat of the adapter 300 surrounding the end of the lamp unit 12 is generated. It is transmitted to the first and second heat radiating portions 320a and 320b. The first and second heat radiating portions 320a and 320b are coil portions wound in a double spiral shape such that wires having a circular cross section are alternately arranged in the length direction at intervals. That is, since the first and second heat radiating portions 120a and 120b have a large surface area in contact with air, the first and second heat radiating portions 120a and 120b come into contact with air, so that the first and second heat radiating portions 120a and 120b The heat of 120b can be efficiently radiated. As a result, the heat generated by the lamp portion 12 of the cold cathode fluorescent lamp 10 can also be radiated efficiently. Moreover, since the connection device 200 is provided with the vent holes 211b, 212a, and 213a in the body 210, air can be circulated to the insertion recess 211 of the body 210 through the vent holes 211b, 212a, and 213a. As a result, the heat at the ends of the adapter 300 and the lamp portion 12 inserted into the insertion recess 211 of the body 210 can be efficiently released. Moreover, since the adapter 300 uses two coils, the conductor cross-sectional area can be increased as compared with the case where one coil is used. Therefore, the electrical resistance of the adapter 300 can be reduced, and the temperature rise of the adapter 300 itself can be suppressed.

また、アダプタ３００は、二本の線材を二重螺旋状に巻くだけで製造することができるので、アダプタ３００の低コスト化を図ることができる。 In addition, since the adapter 300 can be manufactured by simply winding two wires in a double spiral shape, the cost of the adapter 300 can be reduced.

また、アダプタ３００の第１、第２放熱部３２０ａ、３２０ｂが軸方向及び半径方向に弾性変形可能となっているので、前記第２接続状態で、冷陰極蛍光ランプ１０が自身の発熱や外気温の上昇等の外部環境の変化により熱膨張、又は外気温の低下等の外部環境の変化により熱収縮し、リード端子１１及びこれに接続されたアダプタ１００の第１、第２接点部３１０ａ、３１０ｂが熱膨張方向又は熱収縮方向に移動したとしても、第１、第２放熱部３２０ａ、３２０ｂの接続装置２００の接点部２２１とボディ２１０の第２壁部２１３の内壁面との間との間で挟持された部分の前方部分（すなわち、第１、第２放熱部３２０ａ、３２０ｂの前記挟持された部分より第１、第２接点部３１０ａ、３１０ｂ側の部分）が熱膨張方向又は熱収縮方向に（すなわち、軸方向及び／又は半径方向に）弾性変形し、冷陰極蛍光ランプ１０の熱膨張又は熱収縮を吸収することができる。よって、冷陰極蛍光ランプ１０の熱膨張又は熱収縮時に、リード端子１１及びランプ部１２のリード端子１１の根元部分にかかる負荷を低減することができる。また、第１、第２放熱部３２０ａ、３２０ｂの円筒部３２２ａ、３２２ｂの内径は、ランプ部１２が挿入され、前記長さ方向に移動自在となる程度の大きさを有しているので、冷陰極蛍光ランプ１０の熱膨張又は熱収縮時に、前記端部が円筒部３２２ａ、３２２ｂ内で引っ掛かる等して前記端部の移動が妨げられ、これによりリード端子１１及びランプ部１２のリード端子１１の根元部分に負荷がかかるのを防止することもできる。 In addition, since the first and second heat radiating portions 320a and 320b of the adapter 300 can be elastically deformed in the axial direction and the radial direction, the cold cathode fluorescent lamp 10 generates heat and air temperature in the second connection state. The first and second contact portions 310a and 310b of the lead terminal 11 and the adapter 100 connected thereto are thermally expanded due to a change in the external environment such as a rise in temperature, or a thermal contraction due to a change in the external environment such as a decrease in outside air temperature. Between the contact portion 221 of the connection device 200 of the first and second heat radiating portions 320a and 320b and the inner wall surface of the second wall portion 213 of the body 210 even if the heat is moved in the thermal expansion direction or the thermal contraction direction. The front portion of the portion sandwiched between the first and second heat radiation portions 320a and 320b is in the direction of thermal expansion or contraction (ie, the portion closer to the first and second contact portions 310a and 310b than the portion sandwiched). (I.e., in the axial direction and / or radial) elastically deformed can absorb thermal expansion or thermal contraction of the cold cathode fluorescent lamp 10. Therefore, when the cold cathode fluorescent lamp 10 is thermally expanded or contracted, the load applied to the lead terminal 11 and the root portion of the lead terminal 11 of the lamp portion 12 can be reduced. Further, the inner diameters of the cylindrical portions 322a and 322b of the first and second heat radiating portions 320a and 320b have such a size that the lamp portion 12 is inserted and movable in the length direction. When the cathode fluorescent lamp 10 is thermally expanded or contracted, the end portion is caught in the cylindrical portions 322a and 322b and the movement of the end portion is prevented, thereby causing the lead terminal 11 and the lead terminal 11 of the lamp portion 12 to move. It is also possible to prevent a load from being applied to the root portion.

なお、上記アダプタ１００、３００及び接続装置２００は、上記実施例に限定されるものではなく、特許請求の範囲の記載の範囲において任意に設計変更することが可能である。以下、図１１乃至図１３を参照しつつ詳しく説明する。 The adapters 100 and 300 and the connection device 200 are not limited to the above-described embodiments, and can be arbitrarily changed in design within the scope of the claims. Hereinafter, a detailed description will be given with reference to FIGS. 11 to 13.

上記実施例１では、第１、第２接点部は円筒状の座巻部、上記実施例２では第１、第２接点部は所定のコイル間隔をあけて巻かれた二重螺旋状のコイル部であるとしたが、第１、第２接点部は冷陰極蛍光ランプ１０等の電子部品のリード端子に電気的に接続可能である限りどのように設計変更しても構わない。例えば、第１、第２コイル１００ａ、１００ｂを構成する線材の端部を略Ｌ字状に折り曲げて冷陰極蛍光ランプ１０のリード端子１１に接触させることにより、該端部を第１、第２接点部とすることができる。すなわち、第１、第２接点部を略Ｌ字状とすることができる。第１、第２コイル３００ａ、３００ｂについても同様に略Ｌ字状の端部を第１、第２接点部とすることができる。また、実施例１の第１、第２接点部を疎巻き状のコイル部とすることも可能であり、実施例２の第１、第２接点部を円筒状の座巻部とすることも可能である。また、第１、第２接点部のいずれか一方の接点部のみをリード端子１１に接触させるようにしても構わない。この場合、他方の接点部は一方の接点部に接触させ、これにより第１、第２コイルを電気的に接続すれば良い。また、他方の接点部を、一方の接点部ではなく、該一方の接点部側の放熱部に接触させ、これにより第１、第２コイルを電気的に接続することも可能である。 In the first embodiment, the first and second contact portions are cylindrical end winding portions, and in the second embodiment, the first and second contact portions are double spiral coils wound with a predetermined coil interval. However, the design of the first and second contact portions may be changed as long as they can be electrically connected to the lead terminals of the electronic components such as the cold cathode fluorescent lamp 10. For example, by bending the ends of the wires constituting the first and second coils 100a and 100b into a substantially L shape and bringing them into contact with the lead terminals 11 of the cold cathode fluorescent lamp 10, the ends are made the first and second. It can be a contact part. That is, the first and second contact portions can be substantially L-shaped. Similarly, for the first and second coils 300a and 300b, the substantially L-shaped end portions can be used as the first and second contact portions. In addition, the first and second contact portions of the first embodiment can be formed as loosely wound coil portions, and the first and second contact portions of the second embodiment can be formed as cylindrical end winding portions. Is possible. In addition, only one of the first and second contact portions may be brought into contact with the lead terminal 11. In this case, the other contact portion may be brought into contact with the one contact portion, thereby electrically connecting the first and second coils. It is also possible to make the other contact portion contact not the one contact portion but the heat dissipation portion on the one contact portion side, thereby electrically connecting the first and second coils.

また、上記実施例１及び２では、第１、第２接点部は第１、第２放熱部に連続しているとしたが、これに限定されるものではない。例えば、第１、第２接点部と第１、第２放熱部との間に冷陰極蛍光ランプ等の電子部品の熱膨張又は熱収縮を緩和するための弾性変形部を別途設けることも可能である。この弾性変形部は、少なくとも放熱部の軸方向に弾性変形可能になっていれば良い。 In the first and second embodiments, the first and second contact portions are continuous with the first and second heat radiating portions. However, the present invention is not limited to this. For example, it is also possible to separately provide an elastic deformation portion for relaxing thermal expansion or contraction of an electronic component such as a cold cathode fluorescent lamp between the first and second contact portions and the first and second heat radiating portions. is there. This elastic deformation part should just be elastically deformable at least to the axial direction of a thermal radiation part.

上記実施例１では、第１、第２放熱部は疎巻きであるとしたが、前記第１放熱部は、前記本体部の端部が挿入可能なコイル部あり、前記第２放熱部は、前記第１放熱部が挿入されたコイル部である限り、疎巻き及び密巻きのいずれにも任意に設計変更することが可能である。例えば、図１１に示すように、第１、第２コイル１００ａ’、１００ｂ’の円筒部１２２ａ’、１２２ｂ’を、コイル間隔を開けずに密巻きにすることが可能である。この場合であっても、円筒部１２２ａ’、１２２ｂ’の空気に触れる表面積を従来例の円筒状の本体部に比べて大きくすることができるので、放熱効果を向上させることができる。また、第１、第２放熱部の一方のみを疎巻きとすることも可能である。また、円筒部１２２ａ、１２２ｂのコイル間隔が開いている場合であっても、円筒部１２２ｂを構成する線材の間から円筒部１２２ａを構成する線材が外部に露出しないようにすることも可能である。また、上記実施例１では、円筒部１２２ｂの長さ寸法は円筒部１２２ａよりも長さ寸法よりも小さいとしたが、円筒部１２２ａ、１２２ｂの長さ寸法は同じにしても良いし、また、円筒部１２２ｂの長さ寸法が円筒部１２２ａよりも長さ寸法よりも長くなるように設計変更しても構わない。また、実施例１では、第２放熱部の円筒部が接続装置２００のコンタクト２２０の接点部２２１と第２壁部２１３の内壁面との間で挟持されるとしたが、これに限定されるものではない。例えば、第１放熱部１２０ａの円筒部１２２ａの第２放熱部１２０ｂの後方から突出した部分が接続装置２００のコンタクト２２０の接点部２２１と第２壁部２１３の内壁面との間で挟持されるようにしても構わない。また、上記実施例１では、第１、第２放熱部１２０ａ、１２０ｂ全体が弾性変形可能であるとしたが、一部のみが軸方向及び／又は半径方向に弾性変形可能な構成とすることが可能である。例えば、図１１に示すように、第１、第２放熱部１２０ａ’、１２０ｂ’の円錐筒部１２１ａ’、１２１ｂ’だけが軸方向及び半径方向に弾性変形可能な構成とすることができる。 In the first embodiment, the first and second heat dissipating parts are loosely wound, but the first heat dissipating part is a coil part into which an end of the main body part can be inserted, and the second heat dissipating part is As long as it is a coil part in which the first heat radiation part is inserted, it is possible to arbitrarily change the design to either loose winding or dense winding. For example, as shown in FIG. 11, the cylindrical portions 122a 'and 122b' of the first and second coils 100a 'and 100b' can be tightly wound without leaving a coil interval. Even in this case, since the surface area of the cylindrical portions 122a 'and 122b' that come into contact with air can be increased as compared with the cylindrical main body portion of the conventional example, the heat dissipation effect can be improved. Further, only one of the first and second heat radiating portions can be loosely wound. Further, even when the coil intervals of the cylindrical portions 122a and 122b are wide, it is possible to prevent the wire constituting the cylindrical portion 122a from being exposed to the outside from between the wire constituting the cylindrical portion 122b. . In the first embodiment, the length of the cylindrical portion 122b is smaller than the length of the cylindrical portion 122a, but the length of the cylindrical portions 122a and 122b may be the same. The design may be changed so that the length of the cylindrical portion 122b is longer than the length of the cylindrical portion 122a. Moreover, in Example 1, although the cylindrical part of the 2nd thermal radiation part was clamped between the contact part 221 of the contact 220 of the connection apparatus 200, and the inner wall face of the 2nd wall part 213, it is limited to this. It is not a thing. For example, a portion of the cylindrical portion 122a of the first heat radiating portion 120a that protrudes from the rear of the second heat radiating portion 120b is sandwiched between the contact portion 221 of the contact 220 of the connection device 200 and the inner wall surface of the second wall portion 213. It doesn't matter if you do. In the first embodiment, the entire first and second heat radiating portions 120a and 120b are elastically deformable. However, only a part of the first and second heat radiating portions 120a and 120b may be elastically deformable in the axial direction and / or the radial direction. Is possible. For example, as shown in FIG. 11, only the conical cylinder portions 121a 'and 121b' of the first and second heat radiation portions 120a 'and 120b' can be elastically deformed in the axial direction and the radial direction.

上記実施例２では、第１、第２放熱部は疎巻きであるとしたが、二本の線材が前記長さ方向に交互に並ぶように二重螺旋状に巻かれており且つ前記本体部の端部が挿入可能なコイル部である限り、疎巻き及び密巻きのいずれにも任意に設計変更することが可能である。例えば、図１２に示すように、第１、第２コイル３００ａ’、３００ｂ’の円筒部３２２ａ’、３２２ｂ’を、コイル間隔を開けずに密巻きにすることが可能である。この場合であっても、円筒部３２２ａ’、３２２ｂ’の空気に触れる表面積を従来例の円筒状の本体部に比べて大きくすることができるので、放熱効果を向上させることができる。また、上記実施例２では、第１、第２放熱部３２０ａ、３２０ｂ全体が弾性変形可能であるとしたが、一部のみが軸方向及び／又は半径方向に弾性変形可能な構成とすることが可能である。例えば、図１２に示すように、第１、第２放熱部３２０ａ’、３２０ｂ’の円錐筒部３２１ａ’、３２１ｂ’だけが軸方向及び半径方向に弾性変形可能な構成とすることができる。なお、上記実施例１及び２の第１、第２放熱部全体を密巻きにし、弾性変形しない構成とすることも可能である。 In the second embodiment, the first and second heat radiating portions are loosely wound. However, the two wire rods are wound in a double spiral shape so as to be alternately arranged in the length direction, and the main body portion. As long as the end portion of the coil is an insertable coil portion, it is possible to arbitrarily change the design to either loose winding or dense winding. For example, as shown in FIG. 12, the cylindrical portions 322a 'and 322b' of the first and second coils 300a 'and 300b' can be tightly wound without leaving a coil interval. Even in this case, since the surface area of the cylindrical portions 322a 'and 322b' that come into contact with air can be increased as compared with the cylindrical main body portion of the conventional example, the heat dissipation effect can be improved. Moreover, in the said Example 2, although the 1st, 2nd heat radiating part 320a, 320b whole was elastically deformable, only a part may be set as the structure which can be elastically deformed to an axial direction and / or a radial direction. Is possible. For example, as shown in FIG. 12, only the conical tube portions 321a 'and 321b' of the first and second heat radiating portions 320a 'and 320b' can be elastically deformed in the axial direction and the radial direction. In addition, it is also possible to make it the structure which does not elastically deform the 1st, 2nd thermal radiation part whole of the said Examples 1 and 2 by close winding.

上記実施例１及び２では、上記線材が断面円形であるとしたが、これに限定されるものではなく、第１、第２放熱部の空気に触れる表面積が、従来例の円筒状の本体部よりも大きくなり得る形状である限り任意に設計変更することが可能である。なお、第１、第２放熱部を上述の如く密巻きにする場合には、該第１、第２放熱部を構成する線材として断面矩形状の線材を用いることはできない。前記線材を用いて密巻きにすると、従来例と同様の円筒状となるからである。また、上記実施例２では、第１、第２コイル３００ａ、３００ｂを構成する二本の線材が全長において平行で且つ互いに接触しているとしたが、二本の線材の間に隙間があいていても良い。また、二本の線材が逆平行な二重螺旋状に巻かれていても良い。 In the first and second embodiments, the wire has a circular cross section. However, the present invention is not limited to this, and the surface area of the first and second heat radiating portions that contacts the air is the cylindrical main body portion of the conventional example. It is possible to arbitrarily change the design as long as the shape can be larger than that. When the first and second heat radiating portions are closely wound as described above, a wire having a rectangular cross section cannot be used as the wire constituting the first and second heat radiating portions. This is because when the wire rod is used for close winding, a cylindrical shape similar to the conventional example is obtained. In the second embodiment, the two wires constituting the first and second coils 300a and 300b are parallel to each other and are in contact with each other. However, there is a gap between the two wires. May be. Two wires may be wound in an antiparallel double spiral.

また、上記実施例１では、アダプタ１００は、二つの第１、第２コイルを備えているとしたが、これに限定されるものではない。すなわち、アダプタ１００は、三つ以上のコイルを備えた構成とすることも可能である。具体的には、三つ目以上のコイルで第１、第２コイルの周囲を囲い、三以上のコイルを半径方向に多層配置することが可能である。この場合、三つ目以上のコイルの放熱部が第１、第２放熱部の周囲を囲い、前記放熱部が半径方向に三重以上に多層配置されることとなる。また、実施例２では、アダプタ３００は、二つの線材が冷陰極蛍光ランプ１０の長さ方向に交互に並ぶように二重螺旋状に巻き回されて構成された第１、第２コイルを備えているとしたが、これに限定されるものではない。すなわち、アダプタ３００は、三本以上線材が電子部品の長さ方向に交互に並ぶように多重螺旋状に巻き回された構成とすることも可能である。この場合、放熱部も三本以上線材が電子部品の長さ方向に交互に並ぶように多重螺旋状となる。更に、本発明に係るアダプタは、図１３に示すように、一つのコイル１００ａ’’のみを備えた構成とすることも可能である。コイル１００ａ’’のみであっても、従来例の円筒状の本体部に比べて、空気に触れる表面積を大きくすることができるので、その放熱効果を高めることができる。また、前記アダプタはコイルが一つだけであるので、上記実施例１及び２に比べて部品点数を低減することができ、低コスト化を図ることができる。なお、前記アダプタの第１接点部１１０ａ’’及び第１放熱部１２０ａ’’も、上述した第１接点部及び第１放熱部の如く設計変更することが可能であり、第１放熱部１２０ａ’’の一部又は全部を密巻きにすることもできる。 Moreover, in the said Example 1, although the adapter 100 was provided with the two 1st, 2nd coils, it is not limited to this. That is, the adapter 100 can be configured to include three or more coils. Specifically, it is possible to surround the first and second coils with a third or more coils, and to arrange three or more coils in multiple layers in the radial direction. In this case, the heat radiating portions of the third or more coils surround the first and second heat radiating portions, and the heat radiating portions are arranged in multiple layers in the radial direction. In the second embodiment, the adapter 300 includes first and second coils configured such that two wires are wound in a double spiral shape so as to be alternately arranged in the length direction of the cold cathode fluorescent lamp 10. However, it is not limited to this. That is, the adapter 300 can be configured such that three or more wires are wound in a multiple spiral shape so that they are alternately arranged in the length direction of the electronic component. In this case, the heat dissipating part also has a multi-spiral shape so that three or more wires are alternately arranged in the length direction of the electronic component. Furthermore, as shown in FIG. 13, the adapter according to the present invention may be configured to include only one coil 100a ″. Even if only the coil 100 a ″ is used, the surface area in contact with air can be increased as compared with the conventional cylindrical main body, so that the heat dissipation effect can be enhanced. Further, since the adapter has only one coil, the number of parts can be reduced as compared with the first and second embodiments, and the cost can be reduced. The first contact part 110a '' and the first heat radiation part 120a '' of the adapter can also be changed in design like the first contact part and the first heat radiation part described above, and the first heat radiation part 120a '. Some or all of 'can also be tightly wound.
