徴とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a contact for a connector and a method for manufacturing the same, in which a cylindrical connection part of the contact is made from a flat copper alloy plate by deep drawing or other press processing, and the end of the cylindrical connection part is made into a contact member for the contact, that is. The main feature is that the pins and sockets are press-fitted.

コンピュータをはじめ航空宇宙機器、通信機器、工業用
制御機器、計測器など各種電子機器の小型高密度化、性
能向上にともない小型多芯の高信頼性コネクタが大量に
使われるようになった。As various electronic devices such as computers, aerospace equipment, communication equipment, industrial control equipment, and measuring instruments become smaller, more dense, and have improved performance, small, multicore, highly reliable connectors have come into use in large quantities.

そのコネクタのピンコンタクト（第１図）、ソケットコ
ンタクト（第２図）は国の内外を問わず、銅合金丸棒を
旋削してピン１、鍔２、結線（電線圧着）部３、又はソ
ケット４、鍔２、結線部３を作るのが一般であった。The pin contacts (Fig. 1) and socket contacts (Fig. 2) of the connector are made by turning copper alloy round rods, and the pin 1, collar 2, connection (wire crimping) part 3, or socket 4. It was common to make a collar 2 and a connection part 3.

第２図のソケット４は旋削後、フライス加工ににより四
つ割にしてバネ作用を与えている。The socket 4 in FIG. 2 is turned and then cut into quarters by milling to provide a spring action.

このコンタクトは普通、ピンの直径ＩＴｔ嘲後、全長で
１５關前後と小さく、これを旋削加工により月に数百五
個とも数千五個ともいわれる需要を満たす事は困難で、
熱論−個当り価格も高価であった。These contacts are usually small, with a pin diameter of about 15 pins and a total length of about 15 pins, and it is difficult to meet the demand of several hundred to several thousand units per month by turning them.
Hot theory: The price per piece was also expensive.

最近、外国の一部でプレス成形によるものが作られるよ
うになった。Recently, press molding has begun to be made in some foreign countries.

文献の図を模写した第３゜４図がそのピンコンタクト、
第５，６図がそのソケットコンタクトである。Figure 3-4, which is a reproduction of the figure in the literature, shows the pin contact.
Figures 5 and 6 show the socket contacts.

長い帯材５から直角方向へ出た板を丸めてピンコンタク
ト、ソケットコンタクトに成形し、使用時、帯材５から
切離すようにしている。A plate extending perpendicularly from the long strip 5 is rolled up and formed into a pin contact or a socket contact, which is separated from the strip 5 when used.

これは旋削を排し、プレス化した点で量産化に極めて有
効な着想であるが、品質面、寸法精度面で問題があるの
はやむ得ない。This is an extremely effective idea for mass production in that it eliminates turning and uses a press, but there are unavoidable problems in terms of quality and dimensional accuracy.

即ち一枚板を丸めテヒン１、鍔２、結線部３、あるいは
ソケット４、鍔２、結線部３を作るため、結線部３は在
来の旋削された円筒より結線力の弱いＵ形にしなければ
ならなかった事、また在来コンタクトの互換性のためプ
レス化に適した形状に変えられず、細い（ｉｔｎｔｎ前
後）ピン１と太い鍔２とを隣接して巻込み成形するため
真円度、直径寸法、角出しの正確を得るのが容易でない
事、といった問題点がある。In other words, in order to create the hinge 1, flange 2, and connection part 3 by rolling a single plate, or the socket 4, flange 2, and connection part 3, the connection part 3 must be made into a U shape that has a weaker connection force than a conventional turned cylinder. Also, due to the compatibility of conventional contacts, it was not possible to change the shape to a shape suitable for pressing, and because the thin (before and after itntn) pin 1 and the thick flange 2 were rolled and formed adjacent to each other, the roundness was poor. There are problems in that it is not easy to obtain accurate diameter dimensions and cornering.

あるいは、そのピン１だけ別製にしてプレス成形した鍔
２にはめる事も考えられるが、平板を丸めた鍔でピンを
くわえるだけでは、コンタクトの生命である通電性能と
信頼性が低下して問題にならない。Alternatively, it is possible to make only the pin 1 separately and fit it into the press-formed collar 2, but simply holding the pin with the collar made of a flat plate will cause problems as the current carrying performance and reliability, which are the lifeblood of the contact, will deteriorate. do not become.

さて、本発明者はプレス加工の専門家であるが、この種
コンタクトの量産化の要請に対し、単なるプレス化でな
く、従来のコンタクトのあり方そのものを再検討した。Now, the present inventor is an expert in press processing, and in response to the demand for mass production of this type of contact, he reconsidered not just press production, but the conventional method of contact itself.

その結果、第１，２図の在来コンタクトは、バネ作用の
ため靭性を要するソケット４と、圧着加工のため粘性を
要する結線部３とを同一材料とせざるを得ない矛盾、ま
た製作費の６０〜７０％を占める金メッキが着脱接触面
でない鍔２、結線部３にも付いている不経済が認められ
た。As a result, in the conventional contacts shown in Figs. 1 and 2, the socket 4, which requires toughness due to the spring action, and the connection portion 3, which requires viscosity due to the crimping process, are made of the same material, which is a contradiction, as well as a contradiction in that the manufacturing cost is high. It was found that the gold plating, which accounts for 60 to 70%, is also attached to the collar 2 and the connection part 3, which are not contact surfaces for attachment and detachment, which is uneconomical.

第３〜６図のプレス成形したものも、全体を同一材料で
作る矛盾と、前述の結線部３をＵ形にした事による信頼
性減退、形状的な成形の困難性、帯材５などに金をつけ
ないため高価な部分メッキを要する不利等が認められた
。The press-formed ones shown in Figs. 3 to 6 also have problems such as the inconsistency of using the same material as the whole, reduced reliability due to the U-shaped connection part 3, difficulty in shaping due to the shape, and problems such as the band material 5. Disadvantages were recognized, such as requiring expensive partial plating because no gold was attached.

そしてその問題点をすべて解決し、高級コネクタ用コン
タクトとしての性能、信頼性、寸法精度充分で、しかも
安価に量産できるようにする事を敢えてこの発明の目的
とした。The purpose of this invention is to solve all of these problems, to provide a contact with sufficient performance, reliability, and dimensional accuracy as a contact for a high-grade connector, and to be mass-produced at a low cost.

この困難な目的を達成できたのは、生産性が最大のプレ
スによる連続加工により、銅合金板材から円筒状結線部
を作った事、ピン１、ソケット４を夫々、別に最適材料
で量産し、これを上記円筒状結線部に圧入圧着するとい
う構想を得たことによる。We were able to achieve this difficult goal by creating a cylindrical connection part from a copper alloy plate by continuous processing using a press, which has the highest productivity, and by mass-producing the pin 1 and socket 4 separately from optimal materials. This is because we came up with the concept of press-fitting this into the cylindrical connection section.

次に図面を参照して、この発明のコンタクト、及びその
製法を説明する。Next, the contact of the present invention and its manufacturing method will be explained with reference to the drawings.

の銅合金線材を所要寸法に両端成形切断したものである
。The pin 11, like the conventional products shown in FIGS. 1 and 2, is a round bar made by cutting a copper alloy wire rod of a desired thickness to a desired size at both ends.

旋削したもののように先端が球面でなく、交叉した斜面
になるが、実用上支障ない。The tip is not a spherical surface like a turned one, but has an intersecting slope, but this does not pose a practical problem.

ピン１１の基部外周には切断時につけたカシメ用圧痕１
６を点在させている。On the outer periphery of the base of the pin 11 is a caulking impression 1 made during cutting.
6 are scattered.

ピン１１の基部を結線部１３の先端穴へ圧入、圧着した
時、圧痕１６の凹みへ結線部１３側材料が押込まれる効
果がある。When the base of the pin 11 is press-fitted and crimped into the tip hole of the connection part 13, the material on the side of the connection part 13 is pushed into the recess of the impression 16.

結線部１３はこの発明の主体をなすもので、後述のよう
な多段深絞り、絞り出し先端の鍔出し穴明は加工により
平らな銅合金平板から筒状に成形したものである。The connection portion 13 is the main body of the present invention, and is formed into a cylindrical shape from a flat copper alloy plate by multi-stage deep drawing as described later, and the flange hole at the drawing end is formed by processing.

結線部１３の先端穴は接触部材、つまりピン１１又はソ
ケット１４の基部を圧入するに適した寸法、その後部は
電線を挿入、圧着するに適した寸法である。The end hole of the connection part 13 has a size suitable for press-fitting a contact member, that is, the base of the pin 11 or the socket 14, and the rear part has a size suitable for inserting and crimping an electric wire.

詳しくは製法の説明で述べるが、深絞りで絞り出した筒
形の先端を横へ押広げて鍔１２を作り、中央に穴を明は
鍔１２の内側へ縁曲げしたものである。As will be described in detail in the explanation of the manufacturing method, the tsuba 12 is made by pushing the tip of a cylindrical shape drawn out by deep drawing laterally, and a hole in the center is formed by bending the edges to the inside of the tsuba 12.

第９，１０図の結線部１３もほとんど第７，８図のもの
と変りないが、圧入、圧着する部品がピン１１からソケ
ット１４に替ったため、その先端穴もこれに合わせて成
形している。The connection part 13 in Figures 9 and 10 is almost the same as that in Figures 7 and 8, but since the part to be press-fitted and crimped has been changed from the pin 11 to the socket 14, the hole at its end has also been shaped accordingly. There is.

即ち第７図のように作り上げた結線部１３の先端穴をソ
ケット１４の基部１４ａを圧入するに適した寸法、つま

連続プレス成形後、帯材１５から切離したもので、そり
基部にも圧痕１６を作っている。The socket 14 is made by punching out a tough copper alloy strip such as copper or bronze as shown in FIG. After being continuously press-molded into the shape of the spring-type socket 14 shown in FIGS. 9 and 10, it was cut from the band material 15, and an indentation 16 was also made at the base of the warp.

ソケット１４は芯金を挿入して、カシメ成形するから結
線部１３との間に完全な圧着が得られる。Since the socket 14 is formed by inserting a metal core and caulking, a perfect crimping can be obtained between the socket 14 and the connection part 13.

なおピン１１、ソケット１４は夫々、線材、帯材から成
形切断後、結線部１３への圧入前にニッケル下地の金メ
ッキを最も安上りなガラメッキ法で施されている。The pin 11 and the socket 14 are each formed and cut from a wire rod or a strip material, and then gold plated on a nickel base by the cheapest gala plating method before being press-fitted into the connection portion 13.

また結線部１３の方は成形前の銅合金帯板にニッケル又
は錫メッキをしたもので、成形により切捨てる部分がな
いから無駄がない。Further, the connection portion 13 is made of a copper alloy strip plate plated with nickel or tin before forming, and since there is no part cut off during forming, there is no waste.

次にこの発明のコンタクトの製法を説明する。Next, a method for manufacturing the contact of the present invention will be explained.

製法としても、この発明の主な特徴は、従来、コンタク
トは一体の材料から製作すべきもので通電性能、信頼性
、工程増加から分離製作後一体化する製法は問題になら
ないとされた通念を覆えしたところにある。As for the manufacturing method, the main feature of this invention is that it overturns the conventional wisdom that contacts should be manufactured from a single piece of material, and that manufacturing methods in which they are separated and then integrated is not a problem due to current carrying performance, reliability, and increased process steps. It's right there.

またコンタクトの旋削方式をプレス方式に替えるにあた
り、板を丸めて筒状及びＵ形にするという一般的構想を
とらず、板を深絞りして結線部を完全な筒状に成形する
構想を実現したところにある。In addition, when changing the contact turning method to a pressing method, instead of using the general concept of rolling the plate into a cylindrical or U-shaped shape, we realized a concept of deep drawing the plate and forming the connection part into a complete cylindrical shape. It's right there.

これらは溶接接点、つまり銅合金台板に銀接点を抵抗溶
接したものの欠点を圧着方式で解消し性能、信頼性を画
期的に向上させた本発明者の経験と自信にもとづくもの
である。These are based on the experience and confidence of the present inventor, who has solved the drawbacks of welded contacts, that is, resistance-welded silver contacts to a copper alloy base plate, by using the crimping method, and dramatically improved performance and reliability.

入している。During this process, a separately manufactured pin 11 or socket 14 is press-fitted into the wire connection portion 13 at the next processing position after the wire connection portion 13 is completed.

図面によって各加工位置の加工内容を説明すると、加工
位置ａで外円１９を切込みパイロット穴１８も同時に切
込んでいる。To explain the machining contents at each machining position with reference to the drawings, at machining position a, the outer circle 19 is cut and the pilot hole 18 is also cut at the same time.

もし、その前にパイロット穴１８が明けてなければ、同
時に・ こ＼で明ける。If pilot hole 18 has not been drilled before then, drill it at the same time.

外円１９の切込みは深絞りにおける周知技術によるもの
で、内側を切落さないよう二箇所切残している。The cuts in the outer circle 19 are made using a well-known deep drawing technique, and two places are left uncut so as not to cut off the inside.

加工位置すでは切残し位置を９０゜違えて内円２０を切
込んでいる。At the machining position, the inner circle 20 is cut at a 90° difference from the uncut position.

位置ｃ、ｄ、ｅは加工具がない遊び区間で、絞り加工に
よる帯板の上下の動きの影響を少くしている。Positions c, d, and e are play areas where there are no processing tools, and the influence of vertical movement of the strip due to drawing processing is reduced.

加工位置ｆ ｙ ｇ ｙ ｈ 、ｌ ｓ Ｊで第一から
第五まで五段深絞りが行われる。Deep drawing is performed in five stages from the first to the fifth at processing positions f y g y h and l s J.

なお圧入といっても所要圧下刃が小さく単に仮位置決め
する場合から、強い圧下刃で側方からの圧着を行わなく
ても充分な通電性能を生せしめる場合まで変化できるが
、この実施例は前者の場合をとっている。Note that press-fitting can vary from a case where the required reduction blade is small and is simply used for temporary positioning, to a case where a strong reduction blade is used to generate sufficient current carrying performance without crimping from the side, but in this example, the former is used. We take the case of

つまり隣の加工位置０においてサイドパンチと成形カシ
メパンチにより完全圧着している。In other words, at the adjacent processing position 0, the side punch and the forming crimping punch are used to completely press the parts together.

ピン１１（ソケット１４）の基部に前述のような圧痕を
点在させておくことは望ましい。It is desirable that the base of the pin 11 (socket 14) be dotted with indentations as described above.

サイドパンチと成形カシメパンチで圧着する時、圧痕に
材料が押込まれてより強固に一体化されるからである。This is because when crimping is performed using a side punch and a forming caulking punch, the material is pushed into the impression and is more firmly integrated.

ピン、ソケット側も、結線部側も予めメッキされている
ので、圧入圧着のどちらかだけでも良い通電性が得られ
る。Since both the pin and socket sides and the connection side are plated in advance, good electrical conductivity can be obtained by press-fitting only one of them.

なおソケット１４には芯金を入れて圧着する。Note that a core metal is inserted into the socket 14 and crimped.

位置ｐ ｐ ｑ ｐ ｒはｃ、ｄ、ｅ同様の遊び位置で

もプレス技術者の周知技術の応用ゆえ詳細説明を略すが
、第１３図に加工位置ｆの深絞り型を例示する。Detailed explanations of the above-described press working method, processing equipment, and parts supply equipment are omitted because they are applications of techniques well known to press engineers, but a deep drawing die at processing position f is illustrated in FIG. 13.

帯板Ａはタイホルダ２２の穴に沈めた雄型２３、しわ抑
え２４上に停まっている。The strip A is resting on a male die 23 sunk into a hole in a tie holder 22 and a wrinkle suppressor 24.

ポンチホルダ２５を圧下すると雌型２６の下面が帯板Ａ
周辺部をしわ抑え２４との間に挾んで雄型２３沿いに降
下し第１２図加工位置ｆの図のように第１段絞りが行わ
れる。When the punch holder 25 is pushed down, the lower surface of the female die 26 is attached to the band plate A.
The peripheral part is held between the wrinkle suppressor 24 and descends along the male die 23, and the first stage drawing is performed as shown in the processing position f in FIG. 12.

ホルダ２５を引上げると雌型２６と共に帯板Ａが引上げ

る。When the holder 25 is pulled up, the band plate A is pulled up together with the female die 26, so that the push rod 27 pushes it down.

加工位置ｇ−ｊの各深絞り装置も第１３図のものど大差
ない。The deep drawing devices at processing positions g-j are also similar to those shown in FIG. 13.

絞り出した筒部の下側の直径か大きいのは、結線部１３
となって電線を受入れる際、こ″＞に電線の被覆部分を
納めるためである。The diameter of the lower side of the squeezed cylindrical part is larger than the connecting part 13.
This is to accommodate the covered portion of the wire when receiving the wire.

加工位置ｋｙｌ、ｍでは前述の要領で鍔出し穴明けを行
うが、その際、絞り出した筒部が変形しないよう下から
芯金を通すとか、周囲をはさみ支える。At processing positions kyl and m, a flange hole is drilled in the manner described above, but at this time, the cored metal is passed from below or the periphery is supported so that the squeezed cylindrical part does not deform.

これで穴明は鍔出しを同時に行うこともできる。With this, Anaki can also perform Tsubaradashi at the same time.

加工位置ｎ ＋ ０で前述のようにピン１１（又はソケ
ット１４）を圧入圧着する際も上述のような周知の筒部
変形防止策をとる事はいうまでもない。Needless to say, when the pin 11 (or socket 14) is press-fitted at the processing position n + 0 as described above, the well-known measures to prevent deformation of the cylindrical portion as described above are taken.

最後の加工位置Ｓで帯板Ａから切離すのも、周知の打抜
き技術に任せるが、この実施例は帯板Ａ上面に、円形抜
き穴をもち４５°の円錐面つきポンチで結線部１３下縁
を抜き、押下げて切離した。The separation from the strip plate A at the final processing position S is also left to the well-known punching technique, but in this embodiment, the lower part of the connection part 13 is cut using a punch with a circular hole and a 45° conical face on the upper surface of the strip plate A. The edges were pulled out, pressed down and separated.

なお第３〜６図の製品のようにコンタクトを帯材５につ
けて巻取ることが望ましい場合は、加工位置Ｓで完全に
切離さず、一部切残して切離しやすい状態で横へ倒せば
、帯板Ａの残部と共に巻取ることもできる。If it is desirable to attach the contact to the strip 5 and wind it up, as in the products shown in Figures 3 to 6, do not completely cut it off at the processing position S, but leave a portion uncut and lay it to the side so that it can be easily cut off. It can also be rolled up together with the rest of the strip A.

以上、この発明のコンタクト及びその製法を、主として
一実施例について説明したが、これに限定するものでな
く、発明の要旨を変えることなく設計者、プレス技術者
の公知技術によりコンタクトの構造、製法ともに多様に
変化し得る。Above, the contact of the present invention and its manufacturing method have been explained mainly with reference to one embodiment, but the structure and manufacturing method of the contact are not limited to this, and the structure and manufacturing method of the contact are based on the well-known techniques of designers and press engineers without changing the gist of the invention. Both can change in various ways.

例えば結線部先端穴へ圧入圧着する接触部材はピン対ソ
ケットの雄雌型式でなく、先端に頃斜接触面をもつ同形
部材としてもよく、従来の旋削式、及びプレス式コンタ
クトでは考えられなかったような形の接触端をもつコン
タクトが作れる。For example, the contact member that is press-fitted into the tip hole of the connection part is not a pin-to-socket male/female type, but may be a member of the same shape with a diagonal contact surface at the tip, which was unthinkable with conventional turning and press contacts. You can make a contact with a contact end shaped like this.

この発明は、コンタクトを一体構造でなく二部材で作る
事が通電性能、加工工数の面で不可能と考えた従来の常
識を覆えした。This invention overturns the conventional wisdom that it was impossible to make a contact with two parts instead of an integral structure in terms of current carrying performance and processing time.

接触部材と結線部を別に作り、筒状結線部を作るプレス
工程の終りに接触部材を結線部の筒状先端穴へ圧入圧着
したから、充分な通電性能を確保でき、加工工数の増加
も問題にならない。The contact member and the connection part are made separately, and the contact member is press-fitted into the cylindrical tip hole of the connection part at the end of the pressing process to create the cylindrical connection part, so sufficient current carrying performance can be ensured, and the increase in processing man-hours is also an issue. do not become.

圧入圧着された接触部材と結線部の境界は激しい塑性変
形により緊密接触面となり、しかも筒状結線部の円周方
向引張応力により締付けられているから理想的接続状態
となっているのである。The boundary between the press-fitted contact member and the connection portion becomes a tight contact surface due to severe plastic deformation, and is further tightened by the circumferential tensile stress of the cylindrical connection portion, resulting in an ideal connection state.

このような常識破りの三部材接続方式をとった事、結線
部を深絞りによる継目のない筒体とした事により、この
発明は次のような効果を得た。By adopting such an unconventional three-member connection method and by forming the connection portion into a seamless cylindrical body by deep drawing, the present invention achieved the following effects.

（１）ピン、ソケット等、接触部材は結線部と無関係に
最適の材質、形状、加工方法を採用できる。(1) Optimal materials, shapes, and processing methods can be used for contact members such as pins and sockets, regardless of the connection part.

ピンは線材を切断するだけで切削や巻込み加工がなくな
り、ソケットはバネ作用のすぐれたものが得られ、特殊
形状の接触部材も問題なく採用できる。The pin can be made by simply cutting the wire, eliminating the need for cutting or winding, the socket has excellent spring action, and contact members with special shapes can be used without any problems.
