Description
【０００１】0001
本考案は、テレビジョン受像機等の陰極線管（以下ＣＲＴと言う）に高電圧を 供給するフライバックトランスの構造に関するものである。 This invention applies high voltage to cathode ray tubes (hereinafter referred to as CRTs) in television receivers, etc. This relates to the structure of the flyback transformer to be supplied.
【０００２】0002
従来は、図４、図５示すように、高圧コイルボビン７の鍔部２０から延出した 舌片２４の上部に設けた底付円筒部２３の底部中央にある透孔２１に円筒状ター ミナル５を嵌合係止しており、フライバックトランスの絶縁ケース１に設けた筒 体下部２２と高圧コイルボビン７の円筒部２３とを嵌合係止し、絶縁材料１０で 充填封入した後、絶縁ケース１の筒体上部からアノード電圧出力用の高圧リード 線１１を挿入し、絶縁ケースの筒体下部２２と嵌合係止した高圧コイルボビン１ に取付けたターミナル５と圧入接続し、絶縁ケース１の筒体内に絶縁材料１２を 充填し、接続部を封入している。 Conventionally, as shown in FIG. 4 and FIG. A cylindrical tarp is inserted into the through hole 21 at the center of the bottom of the bottomed cylindrical portion 23 provided on the top of the tongue piece 24. A tube that fits and locks the terminal 5 and is provided in the insulating case 1 of the flyback transformer. The lower body part 22 and the cylindrical part 23 of the high-voltage coil bobbin 7 are fitted and locked, and the insulating material 10 is used to After filling and sealing, connect the high voltage lead for anode voltage output from the top of the cylinder of insulation case 1. A high-voltage coil bobbin 1 into which a wire 11 is inserted and is fitted and locked with the lower part 22 of the cylinder of the insulation case. The insulating material 12 is press-fitted into the cylindrical body of the insulating case 1. Filled and encapsulated connections.
【０００３】 この場合、高圧コイルボビン７への巻線は鍔部２０ａ、２０ｂ間で行うため、 ターミナル５を取りつけるための舌片２４や円筒部２３は、鍔部２０ａ、２０ｂ 間より外側に設けなければならない。0003 In this case, since the winding on the high voltage coil bobbin 7 is performed between the flanges 20a and 20b, The tongue piece 24 and the cylindrical part 23 for attaching the terminal 5 are attached to the collar parts 20a and 20b. It must be placed outside the gap.
【０００４】 更に、ターミナル５と高圧リード線１１との接続部から高圧リード線１１の出 口部分まではある程度の絶縁距離が必要となる。なお、出口部分には高圧リード 線１１を絶縁ケース１の筒体の中心に保持するためゴム製の円筒状のホルダー１ ７を取り付けられている。0004 Furthermore, the high voltage lead wire 11 comes out from the connection between the terminal 5 and the high voltage lead wire 11. A certain amount of insulation distance is required up to the mouth part. In addition, there is a high voltage lead at the outlet. A cylindrical rubber holder 1 is used to hold the wire 11 in the center of the cylinder of the insulating case 1. 7 is attached.
【０００５】 このような構造のフライバックトランスは例えば実公昭６０−８４１２号公報 （Ｈ０１Ｆ１９／０４）に示されている。[0005] A flyback transformer with such a structure is disclosed in, for example, Japanese Utility Model Publication No. 8412/1983. (H01F19/04).
【０００６】 以上、従来のフライバックトランスでは、高圧リード線１１の出口の高さは非 常に高くなっており、そのため、テレビジョンのセット内部ではＣＲＴやセット の外装箱との接触を防ぐため、プリント基板上の配置が制限されたり、十分な空 間を取るため、外装箱が大きくなったりする欠点があった。[0006] As mentioned above, in the conventional flyback transformer, the height of the outlet of the high voltage lead wire 11 is As a result, CRTs and other devices inside television sets are In order to prevent contact with the outer box of the There was a drawback that the outer box became large because it took up a lot of space.
【０００７】[0007]
本考案は、上述した欠点を解決するためのものであり、アノード電圧出力用の 高圧リード線の出口部分の高さを低くしたフライバックトランスを提供する事を 目的とする。 The present invention is intended to solve the above-mentioned drawbacks, and is intended to solve the above-mentioned drawbacks. To provide a flyback transformer in which the height of the outlet part of the high voltage lead wire is reduced. purpose.
【０００８】[0008]
本考案は、高圧コイルと高圧リード線とを接続するためのターミナルを絶縁ケ ースの筒体部に取り付けたことを特徴とする。 This invention uses an insulating case as a terminal for connecting the high voltage coil and high voltage lead wire. It is characterized by being attached to the cylindrical part of the base.
【０００９】[0009]
ターミナルの取り付け位置が、高圧コイルボビンの巻線部（鍔間）のほぼ中央 の高さまで低くなり、高圧リード線の出口の高さを低くすることができる。 The terminal installation position is approximately in the center of the winding part (between the collars) of the high voltage coil bobbin. The height of the high-voltage lead wire exit can be lowered.
【００１０】0010
図１に本考案の実施例を示し、図２、図３に高圧リード線とターミナルとの接 続部の拡大図を示す。フライバックトランスの絶縁ケース１に設けた筒体部２の 底部３には透孔４がある。透孔４には、係止縁５ａをもつ、底付円筒状金属ター ミナル５が嵌合係止されている。低圧コイルボビン６と高圧コイルボビン７は巻 線後嵌合係止し、絶縁ケース１に収納後、高圧コイルの終端８とターミナル５と が抵抗素子９を介して、半田付け、溶接等で電気接続される。 Figure 1 shows an embodiment of the present invention, and Figures 2 and 3 show the connection between the high voltage lead wire and the terminal. An enlarged view of the sequel is shown. The cylindrical body part 2 provided in the insulation case 1 of the flyback transformer The bottom part 3 has a through hole 4. The through hole 4 has a bottomed cylindrical metal tartar with a locking edge 5a. The terminal 5 is fitted and locked. The low voltage coil bobbin 6 and the high voltage coil bobbin 7 are After fitting and locking the wires and storing them in the insulating case 1, connect the terminal end 8 of the high voltage coil and the terminal 5. are electrically connected via the resistive element 9 by soldering, welding, or the like.
【００１１】 そして、同じく絶縁ケース１に収納した高圧可変抵抗器等の部品（図示しない ）と共にエポキシ樹脂などの絶縁材料１０で充填封入する。この時、従来の方法 では、ターミナルと高圧コイルボビン、高圧コイルボビンと絶縁ケースで嵌合が あるため、特に、高圧コイルボビンと絶縁ケースとの嵌合部で絶縁材料が絶縁ケ ース筒体内に漏れるという不具合が生じやすいが本考案ではこの問題は生じない という利点もある。[0011] Components such as a high-voltage variable resistor (not shown) also housed in the insulating case 1 ) together with an insulating material 10 such as epoxy resin. At this time, the conventional method Now, the terminal and high voltage coil bobbin, and the high voltage coil bobbin and insulation case are mated together. Therefore, the insulating material may be damaged by the insulating case, especially at the fitting part between the high voltage coil bobbin and the insulating case. However, this problem does not occur with the present invention. There is also an advantage.
【００１２】 次に、絶縁材料１０で充填封入した後、アノード電圧を取り出すための高圧リ ード線１１を絶縁ケース１の筒体部２の上部から挿入した後、エポキシ樹脂など の絶縁材料１２を充填投入する。高圧リード線１１の先端部分は、外被膜１３が 取除いてあり、内被膜１４と内被膜１４を取り除き、内被膜外径に沿って折り曲 げた導体をターミナル３に挿入し、電気接続していることは従来通りである。0012 Next, after filling and sealing with insulating material 10, a high-voltage pipe is used to extract the anode voltage. After inserting the lead wire 11 from the top of the cylindrical part 2 of the insulating case 1, epoxy resin etc. The insulating material 12 is then filled. The tip of the high voltage lead wire 11 is coated with an outer coating 13. The inner capsule 14 is removed, the inner capsule 14 is removed, and the inner capsule is bent along the outer diameter of the inner capsule. As before, the exposed conductor is inserted into the terminal 3 and electrically connected.
【００１３】 そして、１６は円周方向に３ケ所以上設けられたガイドリブであり、高圧リー ド線１１をターミナル５の中心に導くと同時に、ゴム製の円筒状のホルダー１７ とともに高圧リード線１１をケース筒体部１２の中心に保持している。[0013] 16 is a guide rib provided at three or more places in the circumferential direction, and is a high pressure lead. At the same time, a rubber cylindrical holder 17 is guided to the center of the terminal 5. At the same time, the high voltage lead wire 11 is held at the center of the case cylindrical body part 12.
【００１４】 このような構造をしたフライバックトランスでは、ターミナル５の位置が、高 圧コイルボビンの鍔１８ａ、１８ｂの間にすることができるので、絶縁距離を取 るため、筒体２内に充填する絶縁材料１２の深さを十分取っても、高圧リード線 １１の出口の位置１９の高さはあまり高くならない。[0014] In a flyback transformer with such a structure, the position of terminal 5 is The insulation distance can be maintained between the flanges 18a and 18b of the piezo coil bobbin. Therefore, even if the insulating material 12 filled in the cylinder 2 is sufficiently deep, the high voltage lead wire The height of the outlet position 19 of 11 is not very high.
【００１５】 そのため、テレビジョンのセット内部で、フライバックトランスの位置をＣＲ Ｔのネック部分からより画面に近い場所におけるようになり、プリント基板上の 配置の自由度が大きくなったり、外装箱を小さくすることが可能になる。[0015] Therefore, the location of the flyback transformer inside the television set must be determined by CR. From the neck part of the T, it is located closer to the screen, and on the printed circuit board. The degree of freedom in arrangement is increased, and the outer box can be made smaller.
【００１６】[0016]
アノード電圧出力用の高圧リード線の出口の高さが低くなるため、テレビジョ ン受像機のセット内の配置の自由度が大きくなる。また、セットの外装箱を小さ くすることが可能となる。高圧コイルボビンとケースとの嵌合が不要になり、こ の部分での充填する絶縁材料の漏れ不良がなくなる。 The exit height of the high-voltage lead wire for the anode voltage output is lowered, so the TV This increases the degree of freedom in the arrangement of receivers within a set. In addition, the outer box of the set can be made smaller. It becomes possible to reduce the This eliminates the need to fit the high voltage coil bobbin and case together. This eliminates leakage defects of the insulating material to be filled in the parts.
