Description

【0001】
【発明の属する技術分野】
この発明は、民生用の電子機器の高調波対策に用いられるリアクターに関する。
【0002】
【従来の技術】
この種のリアクターは、コイルボビンにコイルを巻回し、かつコイルボビンにコアを組込むとともに、コイルの引出線を端子板に接続するなどして構成されている。
【0003】
この端子板はコイルの外表面に取付けられ、コイルの引出線をその端子板の所定の位置まで引き回わし、かつ所定のリード線と接続している。
【0004】
【発明が解決しようとする課題】
この端子板は、従来、紙製のものが用いられ、この紙製の端子板に端子を設けているが、取付が煩雑であるとともに、引っ張り強度などにも弱い、という課題があった。
【0005】
この発明は上記のことに鑑み提案されたもので、その目的とするところは、端子板に端子を容易、かつ確実に取付けることのできるリアクターを提供することにある。
【0006】
【課題を解決するための手段】
この発明は、端子1と、この端子1が取付けられる樹脂製の端子板2と、この端子板2がリアクター本体3が取付けられた取付板6の端子板取付部6bに取付けられるリアクターであって、前記端子1の上方両側には横方向に張り出した係止部1bが形成され、かつその下方には長手の端子本体に対しほぼ直交して外側に折曲された抜け止め部1cが形成され、かつ前記端子板2には外側に突出した一対の取付部2dが形成され、これら取付部2d間に上方から前記端子1をその抜け止め部1c側から挿通し、前記係止部1bが前記取付部2dの上部に当接後、取付部2dの下方に位置する前記抜け止め部1cを横方向に押し広げ、抜け止め部1cの上部を前記取付部2dの下部と当接させ固定する構成として上記目的を達成している。
また、この場合、抜け止め部1cの上部は傾斜したテーパ状とし、上記目的を達成している。
【0007】
【発明の実施の形態】
図1は本発明の一実施例における、端子を端子板に取付ける状態の正面図、図2は端子の側面図、図3は端子を端子板に取付けた状態の正面図、図4は要部の拡大図を示す。
【0008】
図1において、1は導電性部材からなる平形の端子である。この端子1の上端中央部にはリード線接続部1aが形成されている。また、上部には側方に張り出した係止部1bが形成され、かつその下方の離間した位置には抜け止め部1cが形成されている。さらに、端子1の下方には、詳しくは図5に示す引出線4a,4bを案内して受容する包持部1dが形成されている。この包持部1dは下方両側部に切込みを入れ、かつ両側部を、図2に示すように、外側に向かってほぼ弧状に折曲することによって形成されている。
【0009】
また、図1において、2は絶縁性の樹脂からなる全体としてほぼ矩形をなす端子板である。この端子板2の中央上方には、詳しくは後述の図5に示す端子板取付部6bの係合部6cと係合する係合用窓2aが形成されている。また、端子板2の内部には下方開口部2bを介し端子板取付部6bを挿通するための凹部2cが形成されている。
【0010】
さらに、端子板2の外表面には端子1を取付けるための取付部2dが形成されている。この各取付部2dは外側に向かって突出した一対の突部からなり、そこの根元部分に端子1を上方から挿通する。端子1の上部には、前述のように、側方に張り出した係止部1bがあり、この係止部1bが取付部2dの上端に当接して位置決めされる。また、端子1の抜け止め部1cは、端子挿入時には、長手の端子本体に対しほぼ直交して取付部2dの突出方向に折曲され、一対の取付部2d間に挿入し下方位置にでてきたところで、図3に示すように、横方向に押し広げることにより、端子1が抜け出ないようになっている。
【0011】
図3は端子1の取付状態、図4は図3中A部の拡大図で、抜け止め部1cの上部は上方から下方へ傾斜するテーパ状をなし、取付部2dの下端と当接する。このように、テーパ状にすることによりくさび効果が得られ、カシメ後のガタを無くし、確実に固定することができる。
【0012】
なお、詳しくは図4に示すように、抜け止め部1cの両側部1c′は折曲され、補強されている。
【0013】
図5は端子1が取付けられた端子板2をリアクター本体3に取付ける状態を示す。
【0014】
図5中、4はコイルボビンの胴部上に太目(例えば1.5mm)を電線を巻回して構成したコイル、5はコイルボビンに組込まれたけい素鋼板を積層してなるEI型のコア、6は上記組立体が取付けられた、鉄板の如き金属の板からなり、かつ取付孔6aを有する取付板で、この取付板6にはその一部を上方に向かってほぼ直角に折り曲げて形成した端子板取付部6bが形成されている。
【0015】
この端子板取付部6bにはリブ6cが形成され補強され、かつこれに端子1を有する端子板2が取付けられるが、それに先立ってコイル4の巻始め、巻終わりの各引出線4a,4bを予め所定の形状にフォーミングしておき、端子板取付部6bに端子板2を取付ける際に、各引出線4a,4bが端子1の包持部1dに案内され包持されるようになっている。
【0016】
すなわち、各引出線4a,4bは太線からなるため、線に腰があり、かつその材質に起因して折曲自在であって所定形状にフォーミングすることができる。このフォーミングとしては、引出線4a,4bを所定の長さに切断し、周囲の絶縁被膜を除去し、所定の形状に折曲される。フォーミング作業は手作業でも良いし、ロボットを介して自動化により行っても良い。
【0017】
なお、端子板取付部6bの上部には打抜き形成された舌片状の係合部6dが形成されている。この係合部6dはやや外側に折曲され、端子板2の内部に形成された凹部2cに端子板取付部6bを下方開口部2bを介して挿通して取付ける場合、係合部6dは材質に起因する弾性を有するため、内側に押圧され、先端が係合窓2aの下縁2a′の位置に達すると、押圧状態が解放されるため、外側位置に復帰し、先端が係合窓2aの下縁2a′に係合し、端子板2の抜けを防止することができる。
【0018】
なお、この時点で包持部1dと各引出線4a,4bとが接触される。この接触部分は周知のようにハンダ付け接続される。この場合、包持部1dの外側上部にはその形状に起因してハンダが乗り易い。
【0019】
しかる後、端子板2には絶縁カバー7が取付けられる。この絶縁カバー7の両側部には、一対のアーム7aが突設され、かつアーム7aの先端には内側に折曲された係合部7bが形成され、この部分が取付部2dの側部の根元の段部2d′に係合して絶縁カバー7は端子板2に取付けられる。
【0020】
なお、それぞれ並設された一対の取付部2dのうち内側部分のものには、突部2eがあり、この突部2eは絶縁カバー7の対応した位置に形成された窓7cに係合される。
【0021】
図6は組立が完了した状態の外観斜視図である。
【0022】
【発明の効果】
以上のように、本発明によれば、端子1を端子板2の一対の取付部2d間に位置決めされるまで挿入し、かつ下側に出てきた抜け止め部1cを単に横方向に押し広げるだけで、端子1を容易、かつ確実に端子板2に取付けることができる。また、抜け止め部1cの上部はテーパ状になっているため、取付部2dに対し、いわゆるくさび効果によりガタ付きを防止し得る。

The above purpose is achieved.
Further, in this case, the upper portion of the retaining portion 1c has an inclined taper shape to achieve the above object.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view of a terminal attached to a terminal board according to an embodiment of the present invention, FIG. 2 is a side view of the terminal, FIG. 3 is a front view of the terminal attached to the terminal board, and FIG. The enlarged view of is shown.
[0008]
In FIG. 1, reference numeral 1 denotes a flat terminal made of a conductive member. A lead wire connecting portion 1 a is formed at the center of the upper end of the terminal 1. Further, a locking portion 1b projecting laterally is formed at the upper portion, and a retaining portion 1c is formed at a spaced position below the locking portion 1b. Further, a holding portion 1d for guiding and receiving the lead wires 4a and 4b shown in FIG. 5 is formed below the terminal 1. The holding portion 1d is formed by making cuts in both lower side portions and bending both side portions in a substantially arc shape toward the outside as shown in FIG.
[0009]
In FIG. 1, reference numeral 2 denotes a terminal plate made of an insulating resin and having a substantially rectangular shape as a whole. An engagement window 2a that engages with an engagement portion 6c of a terminal plate attachment portion 6b shown in FIG. Further, a concave portion 2c for inserting the terminal plate attachment portion 6b through the lower opening 2b is formed inside the terminal plate 2.
[0010]
Further, an attachment portion 2 d for attaching the terminal 1 is formed on the outer surface of the terminal plate 2. Each of the mounting portions 2d is composed of a pair of projecting portions projecting outward, and the terminal 1 is inserted into the root portion thereof from above. At the upper part of the terminal 1, as described above, there is a locking portion 1b protruding to the side, and this locking portion 1b is positioned in contact with the upper end of the mounting portion 2d. Further, when the terminal is inserted, the retaining portion 1c of the terminal 1 is bent substantially perpendicular to the longitudinal terminal body in the protruding direction of the mounting portion 2d, inserted between the pair of mounting portions 2d, and comes to a lower position. By the way, as shown in FIG. 3, the terminal 1 is prevented from coming out by being spread in the lateral direction.
[0011]
FIG. 3 is an attached state of the terminal 1, and FIG. 4 is an enlarged view of a portion A in FIG. 3. An upper portion of the retaining portion 1c has a tapered shape that inclines downward from above, and abuts the lower end of the attaching portion 2d. Thus, the wedge effect can be obtained by making the taper shape, and the rattling after the caulking can be eliminated and fixed securely.
[0012]
In detail, as shown in FIG. 4, both side portions 1c 'of the retaining portion 1c are bent and reinforced.
[0013]
FIG. 5 shows a state where the terminal plate 2 to which the terminal 1 is attached is attached to the reactor body 3.
[0014]
In FIG. 5, 4 is a coil formed by winding a thick wire (for example, 1.5 mm) on the body of the coil bobbin, 5 is an EI type core formed by laminating silicon steel plates incorporated in the coil bobbin, 6 Is a mounting plate made of a metal plate, such as an iron plate, to which the assembly is mounted, and having a mounting hole 6a. A terminal formed by bending a part of the mounting plate 6 upward at a substantially right angle. A plate attachment portion 6b is formed.
[0015]
A rib 6c is formed on the terminal plate mounting portion 6b to be reinforced, and a terminal plate 2 having a terminal 1 is mounted on the rib 6c. Prior to this, the lead wires 4a and 4b at the beginning and end of winding of the coil 4 are connected. The lead wires 4a and 4b are guided and held by the holding portion 1d of the terminal 1 when the terminal plate 2 is attached to the terminal plate mounting portion 6b. .
[0016]
That is, since each leader line 4a, 4b is made of a thick line, the line has waist and can be bent due to its material and can be formed into a predetermined shape. As this forming, the lead wires 4a and 4b are cut into a predetermined length, the surrounding insulating film is removed, and the lead wires 4a and 4b are bent into a predetermined shape. The forming operation may be performed manually or may be performed automatically through a robot.
[0017]
A tongue-like engagement portion 6d formed by punching is formed on the upper portion of the terminal plate attachment portion 6b. When the engaging portion 6d is bent slightly outward and the terminal plate mounting portion 6b is inserted through the lower opening 2b into the recess 2c formed inside the terminal plate 2, the engaging portion 6d is made of a material. Therefore, when the tip reaches the position of the lower edge 2a ′ of the engagement window 2a, the pressed state is released, so that the tip returns to the outer position and the tip is engaged with the engagement window 2a. The terminal plate 2 can be prevented from coming off by engaging with the lower edge 2a '.
[0018]
At this time, the holding portion 1d is brought into contact with the lead wires 4a and 4b. This contact portion is soldered as is well known. In this case, the outer upper portion of the holding portion 1d is likely to be soldered due to its shape.
[0019]
Thereafter, an insulating cover 7 is attached to the terminal board 2. A pair of arms 7a project from both sides of the insulating cover 7, and an engagement portion 7b bent inward is formed at the tip of the arm 7a. This portion is the side of the mounting portion 2d. The insulating cover 7 is attached to the terminal plate 2 by engaging with the base step 2 d ′.
[0020]
Of the pair of mounting portions 2d arranged side by side, the inner portion has a protrusion 2e, and this protrusion 2e is engaged with a window 7c formed at a corresponding position of the insulating cover 7. .
[0021]
FIG. 6 is an external perspective view of the assembled state.
[0022]
【The invention's effect】
As described above, according to the present invention, the terminal 1 is inserted until it is positioned between the pair of mounting portions 2d of the terminal plate 2, and the retaining portion 1c that has come out below is simply pushed laterally. Only, the terminal 1 can be easily and reliably attached to the terminal plate 2. Further, since the upper portion of the retaining portion 1c is tapered, it is possible to prevent the mounting portion 2d from being loosened by a so-called wedge effect.
