本考案は、プリント基板に実装するアース端子に関する。 The present invention relates to a ground terminal mounted on a printed circuit board.
【０００２】[0002]
電子機器においては本体に組み込んだプリント基板のアースをシャーシに接続 してアースをとることが必要である。従来、プリント基板のアースをとる場合、 当該プリント基板のアースとシャーシとをアース線で接続していた。このためプ リント基板をシャーシに組み込んだ後アース線をハンダ付けにより接続する必要 があり、組付けの手間がかかるという問題があった。 In electronic equipment, it is necessary to connect the ground of the printed circuit board built into the main body to the chassis to establish the ground. Conventionally, when the printed circuit board is grounded, the grounded circuit board and the chassis are connected by a ground wire. Therefore, it is necessary to connect the ground wire by soldering after mounting the printed circuit board in the chassis, and there is a problem that it takes time and effort to assemble.
【０００３】 そこで、近年、図５に示すようにプリント基板１に素子を実装する際にアース 端子２を実装し、リード２ｂ〜２ｄをプリント基板１の各孔１ａを挿通してアー ス用ランドにハンダ付けにより接続固定した後、リード２ｂ〜２ｄの上端即ち、 プリント基板１の上面近傍位置において接続部２ａを当該プリント基板１に沿っ て略直角に折り曲げ、機器本体にプリント基板１を組み込んだ際に、図６に示す ようにシャーシ側に設けたアース接続部３に接続部２ａを載置し、ねじ挿通孔２ ｅを通してねじ４で電気的及び機械的に接続するようにしている。或いは、図７ に示すようにプリント基板１の上面１ｃにアース端子２の接続部２ａを当接し、 孔２ｅ及びプリント基板１の孔１ｄにねじ４を挿通してアース端子接続部３のね じ孔３ａに螺合し、アース端子２をプリント基板１と共に固定し、且つねじ４を 介して接続部３に電気的に接続している。このようなアース端子２を使用するこ とによりハンダ付け作業がなくなり、組付け作業の能率が向上する。Therefore, in recent years, as shown in FIG. 5, when mounting an element on a printed circuit board 1, a ground terminal 2 is mounted, and leads 2b to 2d are inserted through each hole 1a of the printed circuit board 1 to form an earth land. After being connected and fixed by soldering to the leads, the connecting portion 2a is bent at a substantially right angle along the printed circuit board 1 at the upper ends of the leads 2b to 2d, that is, in the vicinity of the upper surface of the printed circuit board 1, and the printed circuit board 1 is incorporated into the device body. At this time, as shown in FIG. 6, the connecting portion 2a is placed on the ground connecting portion 3 provided on the chassis side, and is electrically and mechanically connected by the screw 4 through the screw insertion hole 2e. Alternatively, as shown in FIG. 7, the upper surface 1c of the printed circuit board 1 is brought into contact with the connecting portion 2a of the ground terminal 2, and the screw 4 is inserted into the hole 2e and the hole 1d of the printed circuit board 1 so that the screw of the ground terminal connecting portion 3 is inserted. The ground terminal 2 is fixed together with the printed circuit board 1 by being screwed into the hole 3a, and is electrically connected to the connecting portion 3 via the screw 4. By using such a ground terminal 2, the soldering work is eliminated and the efficiency of the assembling work is improved.
【０００４】[0004]
ところで、アース端子２は、薄板で形成されており、しかも、細いリード２ｂ によりプリント基板１に固定されているために、シャーシ側のアース接続部３に 接続部２ａをネジ４で締め付け固定する際に締付力により当該接続部２ａが曲が ったり、或いはリード２ｂ〜２ｄの部分が捩じれて変形する等の問題がある。 By the way, since the ground terminal 2 is formed of a thin plate and is fixed to the printed circuit board 1 by the thin lead 2b, when the connection portion 2a is tightened and fixed to the ground connection portion 3 on the chassis side by the screw 4. In addition, there is a problem that the connecting portion 2a is bent by the tightening force, or the portions of the leads 2b to 2d are twisted and deformed.
【０００５】 本考案は上述の点に鑑みてなされたもので、プリント基板に実装したアース端 子をシャーシ側のアース接続部にねじ止め固定する際に、ねじの締付力により変 形することを防止するようにしたアース端子を提供することを目的とする。The present invention has been made in view of the above points, and when the ground terminal mounted on the printed circuit board is screwed and fixed to the ground connection portion on the chassis side, it is deformed by the tightening force of the screw. It is an object of the present invention to provide a ground terminal designed to prevent the above.
【０００６】[0006]
上記目的を達成するために本考案によれば、プリント基板に実装され、ねじ挿 通孔が穿設された接続部の下端に一体に形成された複数のリードが前記プリント 基板のアースに夫々接続され、前記接続部が前記プリント基板の上面近傍位置で 折曲されてシャーシ側のアース接続部にねじ止め固定されて前記プリント基板の アースを前記シャーシに電気的に接続するアース端子において、前記接続部のね じ挿通孔の周縁に突起を複数形成した構造としたものである。 To achieve the above object, according to the present invention, a plurality of leads, which are mounted on a printed circuit board and integrally formed at a lower end of a connection portion having a screw insertion hole, are connected to the ground of the printed circuit board, respectively. The connection terminal is bent at a position near the upper surface of the printed circuit board and is screwed and fixed to the ground connection section on the chassis side to electrically connect the ground of the printed circuit board to the chassis. This is a structure in which a plurality of protrusions are formed on the periphery of the screw insertion hole of the portion.
【０００７】[0007]
プリント基板にアース端子を装着して当該プリント基板のアースにリードを接 続し、プリント基板にアース端子を実装した後、プリント基板の上面近傍位置に おいて接続部を略当該プリント基板に沿って折曲する。アース端子の接続部は、 各突起の先端がシャーシ側のアース接続部に当接してねじ止め固定される。これ によりアース端子は、ねじの締付時に接続部が回ることが防止され、リードが捩 じれ変形することが防止される。また、接続部は、各突起がアース接続部と点接 触することにより電気的に良好に接続される。 Attach the ground terminal to the printed circuit board, connect the lead to the ground of the printed circuit board, mount the ground terminal on the printed circuit board, and place the connection part near the upper surface of the printed circuit board along the printed circuit board. Fold. At the connection portion of the ground terminal, the tip of each protrusion abuts on the ground connection portion on the chassis side and is fixed by screwing. This prevents the connection portion of the ground terminal from rotating when the screw is tightened, and prevents the lead from being twisted and deformed. Further, the connection portion is electrically connected well by the point contact of each protrusion with the ground connection portion.
【０００８】[0008]
以下本考案の一実施例を添付図面に基づいて詳述する。 図１において、アース端子５は、接続部５ａの下端の左右両側及び中央に３本 のリード５ｂ〜５ｄが一体に形成されており、これらのリード５ｂ〜５ｄの各下 端は基部５ｅに連設されている。そして、基部５ｅには位置決め用の孔５ｆが所 定の間隔で穿設されている。接続部５ａは、図のように上下に僅かに長い矩形状 をなし、上端は半円状の円弧とされ、長手方向に沿って上端近傍から略中央に至 る長孔５ｇが穿設されている。この長孔５ｇは、ねじ挿通孔とされる。 An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In FIG. 1, the ground terminal 5 is integrally formed with three leads 5b to 5d on the left and right sides and the center of the lower end of the connecting portion 5a, and the lower ends of these leads 5b to 5d are connected to the base portion 5e. It is set up. The base 5e is provided with positioning holes 5f at predetermined intervals. As shown in the figure, the connecting portion 5a has a rectangular shape that is slightly elongated vertically and has a semicircular arc at the upper end, and a long hole 5g is formed along the longitudinal direction from the vicinity of the upper end to the approximate center. There is. The elongated hole 5g is a screw insertion hole.
【０００９】 そして、接続部５ａには、長孔５ｇの周縁に突起５ｈが複数例えば、４個設け られている。これらの突起５ｈは、図２に示すように接続部５ａの一側から他側 に即ち、矢印Ａで示すねじ締付方向に膨出しており、プレス加工により形成され ている。そして、突起５ｈの先端がシャーシ側のアース接続部に当接するように なっている。尚、突起５ｈは、４個に限るものではなく、３個或いは５個でも良 いことは勿論である。また、各突起５ｈ間の間隔はできるだけ等間隔にすること が好ましい。The connection portion 5a is provided with a plurality of protrusions 5h, for example, four protrusions 5h, on the periphery of the elongated hole 5g. As shown in FIG. 2, these protrusions 5h swell from one side of the connecting portion 5a to the other side, that is, in the screw tightening direction indicated by the arrow A, and are formed by press working. Then, the tip of the projection 5h comes into contact with the ground connection portion on the chassis side. The number of protrusions 5h is not limited to four, and it is needless to say that the number of protrusions 5h may be three or five. In addition, it is preferable that the intervals between the protrusions 5h be as uniform as possible.
【００１０】 左右両側のリード５ｂ、５ｄは、段差をなして幅狭とされ、接続部５ａの両側 下端とリード５ｂ、５ｄの各外側部との段差部は、リード５ｂ、５ｄの付根から 斜めに切り上げられている。即ち、接続部５ａの両側下端の隅部が切り上げられ た形状とされている。そして、この鈍角をなして切り上げられた位置Ｐが実装後 の折曲位置とされる。The leads 5b and 5d on both the left and right sides are stepped and narrowed, and the stepped portions between the lower ends on both sides of the connecting portion 5a and the outer portions of the leads 5b and 5d are oblique from the roots of the leads 5b and 5d. It has been rounded up. That is, the corners at the lower ends on both sides of the connecting portion 5a are rounded up. The position P rounded up at the obtuse angle is the bending position after mounting.
【００１１】 また、この折曲位置Ｐにおけるリード５ｂの幅は、当該位置Ｐよりも上方位置 （接続部５ａとリード５ｂとの連設部）における幅よりも幅狭とされており、折 曲位置Ｐの断面積は、リード５ｂの上端の断面積よりも小さくされている。これ により折曲位置Ｐにおける折曲が容易となる。他側のリード５ｄについてもリー ド５ｂと同様に形成されている。Further, the width of the lead 5b at the bending position P is made narrower than the width at a position above the position P (the connecting portion 5a and the lead 5b are continuously provided), and The cross-sectional area at the position P is smaller than the cross-sectional area at the upper end of the lead 5b. This facilitates bending at the bending position P. The lead 5d on the other side is also formed similarly to the lead 5b.
【００１２】 両側のリード５ｂ、５ｄと中央のリード５ｃとの間の接続部５ａの下端は大き く切り欠かれており、当該リード５ｃと接続部５ａとの連設位置は、リード５ｂ 、５ｄと接続部５ａとの連設位置よりも高い位置になっている。これにより実装 後における中央のリード５ｃの折曲が容易となる。 このアース端子５は、導電性を有する薄い帯板に基部５ｅが連続して打ち抜き 加工により多数形成され、連続せる基部５ｅが帯状の台紙にベルティングテープ （共に図示せず）により貼着されてテーピングアース端子とされている。The lower end of the connecting portion 5a between the leads 5b, 5d on both sides and the central lead 5c is notched to a large extent, and the lead 5c and the connecting portion 5a are continuously connected at the lead 5b, 5d. Is higher than the continuous position of the connection portion 5a and the connection portion 5a. This facilitates bending of the central lead 5c after mounting. The ground terminal 5 has a large number of base portions 5e continuously formed by punching on a thin conductive strip plate, and the base portions 5e to be continuous are attached to a strip-shaped mount with a belting tape (both not shown). It is used as a taping ground terminal.
【００１３】 以下に作用を説明する。 テーピングされたアース端子５は、プリント基板への実装時に供給装置により 基部５ｅからリード５ｂ〜５ｄが所定長さに切り離され、これらのリード５ｂ〜 ５ｄが前記プリント基板に穿設された各孔に上方から略垂直に挿入される。この ときリード５ｂ〜５ｄは、折曲位置Ｐまで挿入される。そして、各リード５ｂ〜 ５ｄは、プリント基板の裏面に形成されているアース用のランドにハンダ付けさ れる。このアース端子は、他の電気部品と共にプリント基板に実装される。The operation will be described below. The taped grounding terminal 5 has the leads 5b to 5d separated from the base 5e into a predetermined length by a supply device when mounted on a printed board, and the leads 5b to 5d are inserted into the holes formed in the printed board. It is inserted almost vertically from above. At this time, the leads 5b to 5d are inserted up to the bending position P. The leads 5b to 5d are soldered to a ground land formed on the back surface of the printed board. This ground terminal is mounted on a printed circuit board together with other electric components.
【００１４】 プリント基板１にアース端子５を実装した後、図３に示すように接続部５ａを プリント基板１の上面に沿って略直角に折り曲げる。このとき、アース端子５の 接続部５ａの各突起５ｈは、膨出する各先端がシャーシ側のアース接続部３に臨 んでいる。アース端５の接続部５ａは、プリント基板１が機器本体に装着される 際にシャーシ側のアース接続部３に載置され、長孔５ｇを挿通するねじ４により 固定される。After mounting the ground terminal 5 on the printed board 1, the connecting portion 5 a is bent along the upper surface of the printed board 1 at a substantially right angle as shown in FIG. At this time, the protrusions 5h of the connecting portion 5a of the ground terminal 5 have their bulging tips facing the ground connecting portion 3 on the chassis side. The connecting portion 5a of the ground end 5 is placed on the ground connecting portion 3 on the chassis side when the printed circuit board 1 is mounted on the device body, and is fixed by the screw 4 which is inserted through the elongated hole 5g.
【００１５】 アース端子５は、接続部５ａの各突起５ｈの膨出する各先端がアース接続部３ の上面に当接されて、点接触により電気的に接続される。従って、ねじ４の締付 力により当該ねじ４と共に接続部５ａが回ることが防止され、接続部５ａの曲が り、或いはリード５ｂ〜５ｄの捩じれ変形が防止される。 尚、プリント基板１のシャーシへの取付位置、或いはアース端子５のプリント 基板１への取付が僅かにずれた場合でも、長孔５ｇによりずれが許容され、アー ス端子５を前記シャーシのアース接続部に接続することができる。The ground terminal 5 is electrically connected by point contact with the bulging tips of the projections 5h of the connecting portion 5a being brought into contact with the upper surface of the ground connecting portion 3. Therefore, the tightening force of the screw 4 prevents the connecting portion 5a from rotating together with the screw 4, preventing the bending of the connecting portion 5a or the torsional deformation of the leads 5b to 5d. Even if the mounting position of the printed circuit board 1 on the chassis or the mounting of the ground terminal 5 on the printed circuit board 1 is slightly deviated, the displacement is allowed by the long hole 5g, and the earth terminal 5 is connected to the ground of the chassis. Can be connected to the department.
【００１６】 或いは、図４に示すようにプリント基板１の上面１ｃにアース端子５の接続部 ５ａを当接させ、孔５ｇとプリント基板１の孔１ｄとにねじ４を挿通してアース 端子接続部３のねじ孔３ａに螺合し、アース端子５をプリント基板１と共に固定 し、且つアース端子５の突起５ｈをねじ４のワッシャ４ａに当接させてアース端 子接続部３に電気的に接続するようにしてもよい。Alternatively, as shown in FIG. 4, the upper surface 1c of the printed board 1 is brought into contact with the connecting portion 5a of the ground terminal 5, and the screw 4 is inserted into the hole 5g and the hole 1d of the printed board 1 to connect the ground terminal. The ground terminal 5 is fixed together with the printed circuit board 1 by being screwed into the screw hole 3a of the portion 3, and the protrusion 5h of the ground terminal 5 is brought into contact with the washer 4a of the screw 4 to electrically connect to the ground terminal connecting portion 3. You may make it connect.
