Description
【０００１】[0001]
本考案は、例えばプリント基板に実装されたチョーク・トランス類を器具本体 で保持する構造に関する。 The present invention relates to a structure in which choke transformers mounted on a printed circuit board are held by an instrument body.
【０００２】[0002]
従来のチョーク・トランス類は、図６に示されるように、コア１、コイル２、 ボビン３、端子ピン４等により構成される。このチョーク８は、図７に示すプリ ント基板５に実装され、両者の結合は、プリント基板５にプリントした銅箔（図 示せず）とチョーク８の端子ピン４との半田７によって行われている。 As shown in FIG. 6, conventional choke transformers are composed of a core 1, a coil 2, a bobbin 3, a terminal pin 4 and the like. The choke 8 is mounted on the printed circuit board 5 shown in FIG. 7, and the two are joined by the solder 7 between the copper foil (not shown) printed on the printed circuit board 5 and the terminal pin 4 of the choke 8. There is.
【０００３】[0003]
ところが、上記従来のチョーク・トランス類の実装構造では、チョーク８が大 きく重量が大となったものでは、チョーク９とプリント基板５とからなる実装ブ ロックの輸送時の振動や落下等によって、チョーク８の荷重がプリント基板５に かかり、これが原因となってプリント基板５が割れたり、銅箔の切れや剥がれを 生じるおそれがあった。 However, in the above-mentioned conventional mounting structure of chokes and transformers, when the choke 8 is large and the weight is large, the mounting block composed of the choke 9 and the printed circuit board 5 may be damaged by vibration or drop during transportation. The load of the choke 8 is applied to the printed circuit board 5, and as a result, the printed circuit board 5 may be cracked or the copper foil may be broken or peeled off.
【０００４】 それらを避けるべく、上記実装ブロックを取付ける器具本体６に、チョーク８ を単独で設置する方法があるが、この場合、器具組立工数が増え、コストアップ を招くという欠点がある。 本考案は、上記従来の課題に鑑みてなされたもので、振動や落下等の衝撃時に 実装部品の変位を規制して、プリント基板への荷重負担を軽減できる実装部品の 保持構造を提供することを目的とする。In order to avoid them, there is a method of independently installing the choke 8 in the instrument body 6 to which the mounting block is attached, but in this case, there is a disadvantage that the number of instrument assembling steps increases and the cost increases. The present invention has been made in view of the above conventional problems, and provides a mounting component holding structure capable of reducing the load burden on a printed circuit board by restricting the displacement of the mounting component at the time of impact such as vibration or dropping. With the goal.
【０００５】[0005]
上記課題を解決するために、本考案は、プリント基板に実装された実装部品を 器具本体側で保持する実装部品の保持構造であって、上記実装部品と器具本体と の間に、プリント基板を貫通して器具本体に対する実装部品の変位を規制する保 持体を介在したものである。 In order to solve the above-mentioned problems, the present invention provides a mounting component holding structure in which a mounting component mounted on a printed circuit board is retained on the instrument body side, and a printed circuit board is provided between the mounting component and the instrument body. A holder that penetrates and regulates the displacement of the mounted component with respect to the instrument body is interposed.
【０００６】[0006]
本考案によれば、実装部品と器具本体の間に保持体を介在したので、振動や落 下等による衝撃時に、実装部品が変位するのを防止できる。従って、プリント基 板に荷重がかからず、割れたり、銅箔の切れや剥がれを生じるおそれがない。 According to the present invention, since the holding body is interposed between the mounting component and the instrument body, it is possible to prevent the mounting component from displacing at the time of impact due to vibration or dropping. Therefore, no load is applied to the printed board, and there is no risk of cracking, breaking or peeling of the copper foil.
【０００７】[0007]
本考案の一実施例を図面に基づいて説明する。 本考案に係るチョーク・トランス（実装部品）は、図１に示されるように、コ ア１、コイル２、ボビン３、四本の脚部（保持体）１０、端子ピン４等により構 成されており、このチョーク９とプリント基板５との結合については、従来通り 、端子ピン４とプリント基板５の銅箔（図示せず）との半田付けによって行われ ている。 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a choke transformer (mounting component) according to the present invention comprises a core 1, a coil 2, a bobbin 3, four legs (holding bodies) 10, terminal pins 4 and the like. The connection between the choke 9 and the printed circuit board 5 is carried out by soldering the terminal pins 4 and the copper foil (not shown) of the printed circuit board 5 in the conventional manner.
【０００８】 上記ボビン３の四隅には、図２に示されるように、それぞれ棒状の脚部１０が 一体形成されている。各脚部１０は、端子ピン４の突出方向と平行に延び、その 長さは、端子ピン４よりも長寸に設定されている。これにより、図１に示される ように、脚部１０の先端が器具本体６に当接して、器具本体６に対するプリント 基板５の変位が規制されている。As shown in FIG. 2, rod-shaped leg portions 10 are integrally formed at the four corners of the bobbin 3, respectively. Each leg portion 10 extends in parallel with the protruding direction of the terminal pin 4, and its length is set to be longer than the terminal pin 4. As a result, as shown in FIG. 1, the tips of the legs 10 come into contact with the instrument body 6 and the displacement of the printed circuit board 5 with respect to the instrument body 6 is restricted.
【０００９】 一方、上記プリント基板５には、図１に示されるように、上記各脚部１０に個 別に対応して貫通孔５ａが穿設されており、各貫通孔５ａの孔径は、脚部１０よ りも僅かに大きく、脚部１０は摩擦しない状態で貫通可能となっている。 上記実装ブロックを組立てるにあたっては、まず、チョーク９の各脚部１０を プリント基板５の各貫通孔５ａにそれぞれ貫通させた状態で、端子ピン４をプリ ント基板５に半田７によって結合し、その後、チョーク９とプリント基板５とか らなる実装ブロックを器具本体６に取付ける。このとき、ボビン３から延びた脚 部１０の先端が、器具本体６に当接するので、チョーク９の重量は器具本体６で 受け止められる。従って、振動や落下等の衝撃時においても、チョーク９はプリ ント基板５を振動させるおそれがない。On the other hand, as shown in FIG. 1, the printed circuit board 5 is provided with through holes 5a corresponding to the respective leg portions 10, and the diameter of each through hole 5a is It is slightly larger than the part 10, and the leg part 10 can be penetrated without friction. In assembling the mounting block, first, with the legs 10 of the chokes 9 penetrating through the through-holes 5a of the printed circuit board 5, the terminal pins 4 are joined to the printed circuit board 5 with solder 7, and then, Attach the mounting block consisting of the choke 9 and the printed circuit board 5 to the instrument body 6. At this time, the tips of the legs 10 extending from the bobbin 3 come into contact with the instrument body 6, so that the weight of the choke 9 is received by the instrument body 6. Therefore, there is no possibility that the choke 9 vibrates the printed substrate 5 even when there is an impact such as vibration or drop.
【００１０】 本考案の他の実施例を図３乃至図５に示す。この実施例では、チョーク９’と プリント基板５とからなる実装ブロックが、樹脂製の成形絶縁体１１を介して器 具本体６に保持されている。この成形絶縁体１１は、器具本体６に固定される板 状部１３と、この板状部１３上に立設された四本の弾性突起１２とからなる。各 弾性突起１２の先端には爪部１２ａが設けられており、一方、チョーク９’のボ ビン３には、その側面３ｂに爪部１２ａを案内するガイド溝１５、上面３ｃに爪 部１２ａが係合する係合孔１６が形成されている。該弾性突起１２の高さ寸法は 、爪部１２ａが係合孔１６に係合した状態で、板状部１３に端子ピン４が当接す るように設定されている。Another embodiment of the present invention is shown in FIGS. In this embodiment, a mounting block consisting of a choke 9'and a printed circuit board 5 is held on the equipment main body 6 via a molded insulating body 11 made of resin. The molded insulator 11 is composed of a plate-shaped portion 13 fixed to the instrument body 6 and four elastic protrusions 12 standing on the plate-shaped portion 13. A claw portion 12a is provided at the tip of each elastic protrusion 12, while the bobbin 3 of the choke 9'has a guide groove 15 for guiding the claw portion 12a to the side surface 3b thereof, and a claw portion 12a for the upper surface 3c thereof. Engagement holes 16 that engage with each other are formed. The height of the elastic projection 12 is set so that the terminal pin 4 abuts on the plate-shaped portion 13 in a state where the claw portion 12a is engaged with the engagement hole 16.
【００１１】 上記実装ブロックを組立てるにあたっては、予め、チョーク９’の端子ピン４ をプリント基板５に半田付けし、その後、この実装ブロックを成形絶縁体１１に 押し込む。このとき、図５に示されるように、プリント基板５の貫通孔１４を貫 通した成形絶縁体１１の弾性突起１２は、先端の爪部１２ａが図３の矢印方向Ａ に撓みながらボビン３のガイド溝１５を滑っていき、係合孔１６に弾発的に係合 される。一方、成形絶縁体１１の板状部１３にはチョーク９’の端子ピン４が当 接する。このように、チョーク９’とプリント基板５とからなる実装ブロックは 、成形絶縁体１１と一体となって器具本体６に抜け止め固定されるので、チョー ク９’の保持がより強固となり、プリント基板５の荷重負担が一層軽減される。Before assembling the mounting block, the terminal pins 4 of the choke 9 ′ are soldered to the printed board 5 in advance, and then the mounting block is pushed into the molded insulator 11. At this time, as shown in FIG. 5, the elastic projection 12 of the molded insulating body 11 penetrating the through hole 14 of the printed circuit board 5 has the tip claw portion 12a bent in the direction A of the arrow in FIG. It slides in the guide groove 15 and is elastically engaged with the engagement hole 16. On the other hand, the terminal pin 4 of the choke 9 ′ contacts the plate-shaped portion 13 of the molded insulator 11. In this way, the mounting block consisting of the choke 9'and the printed circuit board 5 is integrally fixed to the tool body 6 together with the molded insulator 11, so that the choke 9'is more firmly held and the printed matter is printed. The load on the substrate 5 is further reduced.
【００１２】 なお、図３及び図４において、ボビン３の側面３ｂと上面３ｃに、爪部１２ａ のガイド溝１５と係合孔１６を形成したけれど、これに限るものではなく、例え ばボビンの他の部分３ａ、或いはコア１の上面等であってもよい。 上記実施例では、実装部品をチョークで説明したけれども、これに限定されず 、トランス等の重量物であってもよい。Although the guide groove 15 and the engagement hole 16 of the claw portion 12a are formed on the side surface 3b and the upper surface 3c of the bobbin 3 in FIGS. 3 and 4, the invention is not limited to this, and, for example, the bobbin It may be another portion 3a, the upper surface of the core 1, or the like. In the above-mentioned embodiment, the mounting component is described as a choke, but the mounting component is not limited to this and may be a heavy object such as a transformer.
【００１３】[0013]
本考案は、上述したように、保持体によって実装部品の変位を規制したので、 振動や落下等の衝撃によってプリント基板が振動するおそれがない。その結果、 輸送時などにおいてプリント基板の割れ等を確実に防止できる。 In the present invention, as described above, the displacement of the mounted component is restricted by the holding body, so that there is no fear that the printed circuit board will vibrate due to shock such as vibration or drop. As a result, it is possible to reliably prevent the printed circuit board from cracking during transportation.
