【産業上の利用分野】[Industrial applications]

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.

【従来の技術】[Prior art]

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.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、アース端子2の接続部2aとシャーシ側のアース接続部3とは平面 同士が当接してねじ4により締め付けられて接続されるために、これらの当接面 に塵埃、或いは油膜等が附着した場合、これらが絶縁層を形成することとなり、 アース端子2の接続部2aとシャーシ側のアース接続部3とが電気的に接触不良 となる虞れがある。 By the way, since the connecting portion 2a of the earth terminal 2 and the earth connecting portion 3 on the chassis side are brought into contact with each other by being brought into contact with each other by being brought into contact with each other and tightened by the screw 4, dust or an oil film is attached to these contact surfaces. In such a case, these will form an insulating layer, and there is a risk that the connection portion 2a of the ground terminal 2 and the ground connection portion 3 on the chassis side will electrically fail.

【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 子とシャーシ側のアース接続部とを電気的に確実に接続し得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-mentioned points, and provides an earth terminal capable of electrically and surely connecting an earth terminal mounted on a printed circuit board and an earth connecting portion on the chassis side. The purpose is to

【課題を解決するための手段】[Means for Solving the Problems]

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、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 じ挿通孔の周縁に先端が尖った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 portion is bent at a position near the upper surface of the printed circuit board and is screwed and fixed to the ground connection portion on the chassis side, and the ground terminal for electrically connecting the ground of the printed circuit board to the chassis is connected to the connection terminal. In this structure, a plurality of protrusions having sharp tips are formed on the periphery of the screw insertion hole of the portion.

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、 各突起の尖った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 。接続部の各突起の尖った先端は、ねじにより締め付けられる際にシャーシ側の アース接続部に食い込み、当該アース接続部に附着せる塵、塵埃等の絶縁層を破 壊してアース接続部と接触する。これによりアース端子とアース接続部とが電気 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 ground terminal connection part, the sharp tip of each protrusion abuts the ground connection part on the chassis side and is fixed by screws. The sharp tip of each protrusion of the connection part bites into the ground connection part on the chassis side when tightened with a screw, destroys the insulating layer of dust, etc. attached to the ground connection part and contacts the ground connection part. . As a result, the ground terminal and the ground connection section are electrically connected well.

【実施例】【Example】

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. The connecting portion 5a has a rectangular shape that is slightly elongated vertically as shown in the figure, 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の周りに、且つ一端が当該長孔5gの壁面 に開口する先端の尖った断面V字状の突起5hが複数例えば、3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の尖った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、3個に限るものではなく、4個或いは5個でも良い ことは勿論である。The connecting portion 5a is provided with a plurality of, for example, three projections 5h having a V-shaped cross-section with a sharp tip around the elongated hole 5g and one end of which is open to the wall surface of the elongated hole 5g. It 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. The sharp tip of the protrusion 5h comes into contact with the ground connection portion on the chassis side. The number of protrusions 5h is not limited to three, but may be four or five.

【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、5dの幅は、当該位置Pよりも上 方位置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 、5d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。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。Further, the width of the leads 5b, 5d at the bending position P is made narrower than the width at the position above the position P, and the cross-sectional area of the bending position P is the lead 5b, It is made smaller than the cross-sectional area of the upper end of 5d. This facilitates bending at the bending position P. The lower end of the connecting portion 5a between the leads 5b, 5d on both sides and the central lead 5c is largely cut out, and the position where the lead 5c and the connecting portion 5a are continuously connected is set to the lead 5b, 5d and the connecting portion. It is located at a position higher than the continuous position with 5a. This facilitates bending of the central lead 5c after mounting.

【0012】 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。 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 ground terminal 5 has a large number of bases 5e continuously formed by punching on a thin conductive strip, and the bases 5e to be continuous are attached to a strip-shaped mount with a belting tape (both not shown). It is worn as a taping ground terminal. 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.

【0013】 プリント基板にアース端子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, the connecting portion 5 a is bent at a substantially right angle along the upper surface of the printed board 1 as shown in FIG. At this time, the protrusions 5h of the connecting portion 5a of the grounding terminal 5 have their bulging tips facing the grounding connecting portion 3 on the chassis side. The connecting portion 5a of the grounding end 5 is mounted on the grounding 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.

【0014】 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 の上面に当接される。これらの突起5hは、接続部5aがねじ4により締め付け られるにともない、尖った先端がアース接続部3の表面に食い込む。このときア ース接続部3の表面に附着している塵埃、或いは油膜等の絶縁層が突起5hの尖 った先端により破壊され、各突起5hの先端が夫々アース接続部3に接触する。 これによりアース端子5の接続部5aがアース接続部3に電気的に良好に接続さ れる。In the grounding terminal 5, the protruding ends of the protrusions 5h of the connecting portion 5a are brought into contact with the upper surface of the grounding connecting portion 3. These projections 5h have sharp tips biting into the surface of the ground connection portion 3 as the connection portion 5a is tightened by the screw 4. At this time, the dust or the insulating layer such as an oil film attached to the surface of the ground connection portion 3 is broken by the sharp tips of the projections 5h, and the tips of the projections 5h come into contact with the ground connection portion 3, respectively. As a result, the connection portion 5a of the ground terminal 5 is electrically connected to the ground connection portion 3 in an excellent condition.

【0015】 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。 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。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 displaced, the displacement is allowed by the elongated hole 5g, and the earth terminal 5 is attached to the chassis. Can be connected to the ground connection of. Alternatively, as shown in FIG. 4, the connecting portion 5a of the ground terminal 5 is brought into contact with the upper surface 1c of the printed circuit board 1, and the screw 4 is inserted into the hole 5g and the hole 1d of the printed circuit board 1 to connect the ground terminal connecting portion 3 with each other. The ground terminal 5 is fixed together with the printed circuit board 1 by screwing into the screw hole 3a, and the projection 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.
