Description

本発明は、コネクタに関し、特に、コネクタのコンタクト群を形成するための中間部材としてのリードフレームに関する。   The present invention relates to a connector, and more particularly to a lead frame as an intermediate member for forming a contact group of the connector.

対をなす２本の信号線にそれぞれ逆位相の信号からなる差動信号対を伝送する差動伝送方式が知られている。その差動伝送方式はデータ伝送速度を高速にできるという特長をもつため、昨今では様々な分野において実用されている。   A differential transmission method is known in which a differential signal pair consisting of signals having opposite phases is transmitted to two signal lines forming a pair. Since the differential transmission system has a feature that the data transmission speed can be increased, it has recently been put into practical use in various fields.

例えば機器と液晶ディスプレイとの間のデータ伝送に差動伝送方式を用いる場合には、機器及び液晶ディスプレイに、ディスプレイポート規格にしたがって設計されたディスプレイポートコネクタを備える。このディスプレイポート規格としては、VESA Display Port standard 1.0やそれのVersion 1.1aが知られている。   For example, when the differential transmission method is used for data transmission between the device and the liquid crystal display, the device and the liquid crystal display are provided with a display port connector designed according to the display port standard. As this display port standard, VESA Display Port standard 1.0 and its version 1.1a are known.

このディスプレイポートコネクタは差動信号用コネクタの一種であり、接続相手に接続するための第１の接続側と、機器や液晶ディスプレイの基板に接続するための第２の接続側とを有している。第１の接続側の形態は接続相手との関係があるためディスプレイポート規格により厳密に定められているが、第２の接続側の形態は比較的自由である。この種の差動信号用コネクタは特許文献１に開示されており、ハウジングとそのハウジングに保持されたコンタクト群とを備えている。   This display port connector is a kind of connector for differential signals, and has a first connection side for connection to a connection partner and a second connection side for connection to a substrate of a device or a liquid crystal display. Yes. The first connection side configuration is strictly determined by the display port standard because of the relationship with the connection partner, but the second connection side configuration is relatively free. This type of differential signal connector is disclosed in Patent Document 1 and includes a housing and a contact group held in the housing.

コンタクト群は、図８に示すように、互いに間隔をおいて配置された３本のグランドコンタクト１と、それらのグランドコンタクト１の間にペアをなして配置された２対の信号コンタクト２とを含んでいる。コネクタの第１の接続側では、グランドコンタクト１の一端１ａと信号コンタクト２の一端２ａが一直線上に隣接配置されている。さらに、グランドコンタクト１及び信号コンタクト２は、互いに平行にのびた後、互いにずれた位置で同方向に直角に曲がっている。こうして、コネクタの第２の接続側では、グランドコンタクト１の他端１ｂを台形の長辺の両端に位置させ、また、信号コンタクト２の他端２ｂをその台形の短辺の両端に位置させている。さらに、ペアをなす信号コンタクト２の他端２ｂの間隔を広げるため、他端２ｂの近傍で両者を互いに外側に少し曲げ形成している。そして、接続対象のスルーホールにグランドコンタクト１の他端１ｂ及び信号コンタクト２の他端２ｂを挿入し、半田付けにて接続対象に接続される。   As shown in FIG. 8, the contact group includes three ground contacts 1 that are spaced apart from each other, and two pairs of signal contacts 2 that are arranged in pairs between the ground contacts 1. Contains. On the first connection side of the connector, one end 1a of the ground contact 1 and one end 2a of the signal contact 2 are adjacently arranged on a straight line. Further, the ground contact 1 and the signal contact 2 extend parallel to each other, and then bend at right angles in the same direction at positions shifted from each other. Thus, on the second connection side of the connector, the other end 1b of the ground contact 1 is positioned at both ends of the long side of the trapezoid, and the other end 2b of the signal contact 2 is positioned at both ends of the short side of the trapezoid. Yes. Further, in order to increase the distance between the other ends 2b of the paired signal contacts 2, both are slightly bent outward from each other in the vicinity of the other end 2b. Then, the other end 1b of the ground contact 1 and the other end 2b of the signal contact 2 are inserted into the through hole to be connected and connected to the connection target by soldering.

上述したコンタクト群によると、第２の接続側では、グランドコンタクト１の他端１ｂと信号コンタクト２の他端２ｂとが異なる列に配置される上に、ペアをなす信号コンタクト２の他端２ｂの間隔も広げられているため、接続対象に接続する作業が容易になる。   According to the contact group described above, on the second connection side, the other end 1b of the ground contact 1 and the other end 2b of the signal contact 2 are arranged in different rows, and the other end 2b of the paired signal contact 2 is also provided. Since the interval is also widened, it becomes easy to connect to the connection target.

特許第４４３９５４０号公報（特開２００８−４１６５６号公報）Japanese Patent No. 4439540 (Japanese Patent Laid-Open No. 2008-41656)

特許文献１に開示されたコンタクト群は金属板から一括して製造することができる。その場合、先ず、金属板に打ち抜き加工を施すことにより、リードフレームと呼ばれる中間部品を製造する。そのリードフレームは、コンタクト群となる一平面上に並んだ複数のリードと、これらのリードの一端を連結した連結部とを有する。   The contact group disclosed in Patent Document 1 can be manufactured collectively from a metal plate. In that case, first, an intermediate part called a lead frame is manufactured by punching a metal plate. The lead frame has a plurality of leads arranged on one plane as a contact group, and a connecting portion connecting one end of these leads.

しかし、コンタクト群の狭ピッチ化を図る場合には、リードを互いに接近させざるを得ないため、リードとリードとの間に打ち抜き加工が困難な箇所が生じる。特に、特許文献１のように間隔を部分的に広げたペアの信号コンタクトを形成するには、そのための対のリードに予め間隔を部分的に広げた形状をもたせることが必要になるため、その両隣のリードとの間隔が極めて狭くなり、打ち抜き加工が適用できない虞がある。   However, in order to reduce the pitch of the contact group, the leads must be brought close to each other, so that there is a place where punching is difficult between the leads. In particular, in order to form a pair of signal contacts with a partially expanded spacing as in Patent Document 1, it is necessary to have a pair of leads for that purpose having a shape with a partially expanded spacing in advance. There is a possibility that the distance between the adjacent leads becomes extremely narrow and the punching process cannot be applied.

それ故に本発明の目的は、狭ピッチのコンタクト群を容易に得ることを可能にするリードフレームを提供することにある。   Therefore, an object of the present invention is to provide a lead frame that makes it possible to easily obtain a contact group having a narrow pitch.

本発明の他の目的は、上記リードフレームを用いて狭ピッチ化したコンタクト群を有するコネクタを提供することにある。   Another object of the present invention is to provide a connector having a contact group with a narrow pitch using the lead frame.

本発明の一態様によれば、コネクタのコンタクト群を形成するための中間部材としてのリードフレームであって、一平面上に配置された複数の第１のリードと、前記第１のリード間にペアをなして配置された第２のリードと、前記第１のリード及び前記第２のリードを一端側で連結した連結部とを含み、前記第２のリードのペアは、ピッチを前記一端側に比べて他端側で大きくされており、前記第１のリードの各々は、前記連結部からのびた第１の直線部と、前記第１の直線部から、前記第２のリードから離れるように斜めにのびた第１のオフセット部と、前記第１のオフセット部から、前記第１の直線部と同じ方向にのびた第２の直線部とを有することを特徴とするリードフレームが得られる。   According to one aspect of the present invention, there is provided a lead frame as an intermediate member for forming a contact group of a connector, and a plurality of first leads arranged on one plane and the first leads A second lead arranged in a pair, and a connecting portion connecting the first lead and the second lead on one end side, and the second lead pair has a pitch on the one end side And the first leads are separated from the second lead from the first straight portion extending from the connecting portion and the first straight portion. A lead frame having a first offset portion extending obliquely and a second straight portion extending from the first offset portion in the same direction as the first straight portion is obtained.

本発明の他の態様によれば、上記リードフレームを中間部材として用いたコンタクト群を含み、前記第１のリード及び前記第２のリードが前記第１の折曲予定部及び前記第２の折曲予定部でそれぞれ前記一平面に交差する方向に折り曲げられ、かつ、前記連結部が前記第１のリード及び前記第２のリードから切除されてなることを特徴とするコネクタが得られる。   According to another aspect of the present invention, it includes a contact group using the lead frame as an intermediate member, and the first lead and the second lead are the first bent portion and the second folded portion. A connector is obtained in which each of the planned bent portions is bent in a direction crossing the one plane, and the connecting portion is cut off from the first lead and the second lead.

本発明によれば、狭ピッチのコンタクト群を容易に得ることを可能にするリードフレームが得られる。   According to the present invention, a lead frame that makes it possible to easily obtain a contact group with a narrow pitch is obtained.

また本発明によれば、上記リードフレームを用いて狭ピッチ化したコンタクト群を有するコネクタが得られる。   Further, according to the present invention, a connector having a contact group with a narrow pitch using the lead frame can be obtained.

図１及び図２を参照して、本発明の実施形態に係るコネクタについて説明する。   With reference to FIG.1 and FIG.2, the connector which concerns on embodiment of this invention is demonstrated.

このコネクタ１０はプリント基板１１の端部に搭載される差動信号用コネクタであり、多数の導電性の上側コンタクト（コンタクト群）１２と、多数の導電性の下側コンタクト１３と、これらのコンタクト１２，１３を保持した絶縁性のハウジング１４と、これらを取り囲んだ導電性のコネクタシェル１５とを含んでいる。プリント基板１１には、端部に切欠き１１ａが形成されている。なお、コンタクト１２，１３はそれぞれ、図２における紙面に垂直な方向に配列されている。   The connector 10 is a differential signal connector mounted on an end portion of a printed circuit board 11, and includes a large number of conductive upper contacts (contact group) 12, a large number of conductive lower contacts 13, and these contacts. Insulating housing 14 holding 12 and 13 and conductive connector shell 15 surrounding them are included. The printed board 11 has a notch 11a at the end. The contacts 12 and 13 are arranged in a direction perpendicular to the paper surface in FIG.

ハウジング１４は、プリント基板１１の切欠き１１ａに挿入される第１の部分１４ａと、第１の部分１４ａからプリント基板１１の下面に沿ってのびた第２の部分１４ｂとを有している。上側コンタクト１２は、第１の部分１４ａから第２の部分１４ｂにかけて曲がりを伴ってのび、かつ、プリント基板１１に形成されているスルーホールに挿通されて半田付け接続される端子部１２ａを有する。下側コンタクト１３は、第１の部分１４ａから第２の部分１４ｂにかけて曲がりを伴ってのび、かつ、プリント基板１１の下面に半田付け接続される端子部１３ａを有する。なお、第１の部分１４ａには、接続相手となる相手コネクタ（図示せず）が嵌合し、上側コンタクト１２及び下側コンタクト１３と電気的に接続される。   The housing 14 includes a first portion 14 a inserted into the notch 11 a of the printed circuit board 11 and a second portion 14 b extending from the first portion 14 a along the lower surface of the printed circuit board 11. The upper contact 12 includes a terminal portion 12a that extends from the first portion 14a to the second portion 14b with a bend and is inserted into a through hole formed in the printed circuit board 11 and soldered. The lower contact 13 has a terminal portion 13a extending from the first portion 14a to the second portion 14b with a bend and soldered to the lower surface of the printed circuit board 11. Note that a mating connector (not shown) that is a connection partner is fitted into the first portion 14 a and is electrically connected to the upper contact 12 and the lower contact 13.

図３を参照すると、上側コンタクト１２のみがコンタクト群として纏めて示されている。図３から分かるように、上側コンタクト１２は端子部１２ａの位置により、３種類に分かれている。即ち、端子部１２ａは３列に分かれて配列されている。上側コンタクト１２のうち端子部１２ａが中間列Ｒ０にあるものをグランドコンタクトと呼ぶ。上側コンタクト１２のうち端子部１２ａが中間列Ｒ０の一側の列Ｒ１にあるものを第１の信号コンタクトと呼ぶ。上側コンタクト１２のうち端子部１２ａが中間列Ｒ０の他側の列Ｒ２にあるものを第２の信号コンタクトと呼ぶ。したがって、図３のコンタクト群は、４本のグランドコンタクトと、４本の第１の信号コンタクトと、２本の第２の信号コンタクトとを有している。なお、グランドコンタクトはプリント基板１１のグランドラインに接続され、また第１及び第２の信号コンタクトはいずれもプリント基板１１の信号ラインに接続されるものである。   Referring to FIG. 3, only the upper contacts 12 are collectively shown as a contact group. As can be seen from FIG. 3, the upper contact 12 is divided into three types depending on the position of the terminal portion 12a. That is, the terminal portions 12a are arranged in three rows. Of the upper contacts 12, the terminals 12a in the intermediate row R0 are called ground contacts. Among the upper contacts 12, the terminal portion 12a in the row R1 on one side of the intermediate row R0 is referred to as a first signal contact. Among the upper contacts 12, the terminal portion 12a in the other row R2 of the intermediate row R0 is referred to as a second signal contact. Therefore, the contact group of FIG. 3 has four ground contacts, four first signal contacts, and two second signal contacts. The ground contact is connected to the ground line of the printed circuit board 11, and the first and second signal contacts are both connected to the signal line of the printed circuit board 11.

このように、コネクタの第１の接続側では、グランドコンタクトの一端と信号コンタクトの一端は一平面上に隣接配置されている。さらに、グランドコンタクト及び信号コンタクトは、互いに平行にのびた後、互いにずれた位置で同方向に直角に曲がっている。こうして、コネクタの第２の接続側では、グランドコンタクトの他端（端子部１２ａ）を台形の長辺の両端に位置させ、また、信号コンタクトの他端（端子部１２ａ）をその台形の短辺の両端に位置させている。さらに、ペアをなす信号コンタクトの他端（端子部１２ａ）の間隔を広げるため、後文にて明らかになるように他端（端子部１２ａ）の近傍で両者を互いに外側に少し曲げ形成している。   Thus, on the first connection side of the connector, one end of the ground contact and one end of the signal contact are arranged adjacent to each other on one plane. Further, the ground contact and the signal contact extend in parallel to each other and then bend at a right angle in the same direction at a position shifted from each other. Thus, on the second connection side of the connector, the other end (terminal portion 12a) of the ground contact is positioned at both ends of the long side of the trapezoid, and the other end (terminal portion 12a) of the signal contact is positioned at the short side of the trapezoid. It is located at both ends. Furthermore, in order to widen the distance between the other ends (terminal portions 12a) of the paired signal contacts, both are slightly bent outward from each other in the vicinity of the other end (terminal portion 12a) as will become apparent in the later sentence. Yes.

図４及び図５を参照すると、上述したコンタクト群の製造に使用される中間部材の一例としてのリードフレーム２０が示されている。   4 and 5 show a lead frame 20 as an example of an intermediate member used for manufacturing the contact group described above.

リードフレーム２０は金属板に打ち抜き加工を施して作られたものであり、一平面上に配置された複数の第１のリード２１と、第１のリード２１間にペアをなして配置された第２のリード２２と、同じく第１のリード２１間にペアをなして配置された第３のリード２３と、第１のリード２１、第２のリード２２、及び第３のリード２３を一端側で連結した連結部２４とを含んでいる。第２のリード２２は第１のリード２１よりも連結部２４からの長さを短く作られている。第３のリード２３は第１のリード２１よりも連結部２４からの長さを長く作られている。さらに、第２のリード２２のペア及び第３のリード２３のペアの各々は、金属板の打ち抜き加工に際し、予め前記一端側のピッチＰ１に比べて他端側即ち自由端側のピッチＰ２を大きくされることにより、自由端側では第１のリード２１にそれぞれ近づいている。   The lead frame 20 is made by punching a metal plate, and a plurality of first leads 21 arranged on one plane and a first arranged in pairs between the first leads 21. The second lead 22, the third lead 23, which is also disposed in a pair between the first lead 21, the first lead 21, the second lead 22, and the third lead 23 on one end side. And a connected connecting portion 24. The second lead 22 is made shorter than the first lead 21 from the connecting portion 24. The third lead 23 is made longer than the first lead 21 from the connecting portion 24. Further, each of the pair of the second leads 22 and the pair of the third leads 23 has a larger pitch P2 on the other end side, that is, on the free end side, than the pitch P1 on the one end side in advance when the metal plate is punched. As a result, the first lead 21 is approached on the free end side.

第１のリード２１の各々は、連結部２４からのびた第１の直線部２５と、第１の直線部２５から、ペアをなした第２のリード２２の大きいピッチＰ２を有する部分から離れるように斜めにのびた第１のオフセット部２６と、第１のオフセット部２６から、第１の直線部２５と同じ方向にのびた第２の直線部２７と、第２の直線部２７から、第２のリード２２に近づくように斜めに延びた第２のオフセット部２８と、第２のオフセット部２８から、第１の直線部２５の延長線上にのびた第３の直線部２９とを有している。   Each of the first leads 21 is separated from the first straight portion 25 extending from the connecting portion 24 and the portion having the large pitch P2 of the paired second leads 22 from the first straight portion 25. The second lead from the first offset portion 26 extending diagonally, the first offset portion 26, the second straight portion 27 extending in the same direction as the first straight portion 25, and the second straight portion 27. 22, a second offset portion 28 that extends obliquely so as to approach 22, and a third straight portion 29 that extends from the second offset portion 28 on the extended line of the first straight portion 25.

また第１のリード２１の各々は、第２の直線部２７に、前記一平面に交差する方向に折り曲げるための第１の折曲予定部３１を有する。第２のリード２２の各々は、大きいピッチＰ２を有する部分と連結部２４との間でかつ大きいピッチＰ２を有する部分に隣接した位置に、前記一平面に交差する方向に折り曲げるための第２の折曲予定部３２を有する。   Each of the first leads 21 has a first planned bending portion 31 for bending in a direction intersecting the one plane on the second straight portion 27. Each of the second leads 22 is a second portion for bending in a direction crossing the one plane between the portion having the large pitch P2 and the connecting portion 24 and adjacent to the portion having the large pitch P2. A bent portion 32 is provided.

さらに第１のリード及び前記第２のリードの各々は、連結部２４と第１のオフセット部２６との間、及び、連結部２４と第２折曲予定部３２との間にそれぞれ複数の付加折曲予定部３３を有している。   Further, each of the first lead and the second lead has a plurality of additions between the connecting portion 24 and the first offset portion 26 and between the connecting portion 24 and the second bent portion 32. A bending portion 33 is provided.

図４のリードフレーム２０は、第１のオフセット部２６を設けたことにより、ペアをなした第２のリード２２の自由端側に大きいピッチＰ２を有する部分を設けているにもかかわらず、第１のリード２１と第２のリード２２との間隔を比較的大きくとることができる。したがって、図４のリードフレーム２０はプレス打ち抜き加工により簡単に製造することができる。   The lead frame 20 shown in FIG. 4 is provided with the first offset portion 26, so that the portion having the large pitch P2 is provided on the free end side of the paired second lead 22, although The distance between the first lead 21 and the second lead 22 can be made relatively large. Therefore, the lead frame 20 of FIG. 4 can be easily manufactured by press punching.

そして、図４のリードフレーム２０を、第１の折曲予定部３１、第２折曲予定部３２、及び付加折曲予定部３３で折り曲げると共に、連結部２４を切除する。かくして、４本のグランドコンタクトと、４本の第１の信号コンタクトと、２本の第２の信号コンタクトとからなる図３のコンタクト群を簡単に得ることができる。   Then, the lead frame 20 of FIG. 4 is bent by the first scheduled bending portion 31, the second bent scheduled portion 32, and the additional bent scheduled portion 33, and the connecting portion 24 is cut off. Thus, it is possible to easily obtain the contact group of FIG. 3 including the four ground contacts, the four first signal contacts, and the two second signal contacts.

図４のリードフレーム２０の第２のリード２２のペア及び第３のリードのペアの各々が自由端側のピッチＰ２を大きくされているので、図３のコンタクト群の列Ｒ１及びＲ２の各々において端子部１２ａの間隔が広くなり、第１の信号コンタクトの隣接したもの間や第２の信号コンタクトの隣接したもの間の電気的絶縁を十分に取ることができる。加えて、グランドコンタクトと第１及び第２の信号コンタクトとでは端子部１２ａが異なる列に配置されているので、両者の端子部１２ａの間隔を広く設定して電気的絶縁を十分に取ることができる。したがって、コンタクト群の狭ピッチ化が容易に可能である。   Since each of the second lead 22 pair and the third lead pair of the lead frame 20 of FIG. 4 has a larger pitch P2 on the free end side, in each of the contact group rows R1 and R2 of FIG. The distance between the terminal portions 12a is widened, and sufficient electrical insulation can be obtained between adjacent ones of the first signal contacts and adjacent ones of the second signal contacts. In addition, since the terminal portions 12a are arranged in different rows in the ground contact and the first and second signal contacts, it is possible to set the distance between the terminal portions 12a wide to obtain sufficient electrical insulation. it can. Therefore, it is possible to easily reduce the pitch of the contact group.

さらに、ペアをなした第２のリード２２の大きいピッチＰ２を有する部分から離れるように斜めにのびた第１のオフセット部２６を設けているので、これに引き続く第２の直線部２７とペアをなした第２のリード２２の大きいピッチＰ２を有する部分との間隔を広くとることができる。したがって、打ち抜き加工の適用が容易であるため、狭ピッチのコンタクト群の製造に寄与するリードフレーム２０を提供できる。   Further, since the first offset portion 26 is provided obliquely extending away from the portion having the large pitch P2 of the paired second lead 22, it is paired with the second linear portion 27 following this. The distance between the second lead 22 and the portion having the large pitch P2 can be widened. Therefore, since the punching process can be easily applied, it is possible to provide the lead frame 20 that contributes to the manufacture of a narrow pitch contact group.

また、第１の折曲予定部３１を第２の直線部２７（第１のオフセット部２６と第２のオフセット部２８の中間）に設けているので、結果的に、第１の折曲予定部３１から自由端までの距離、即ち、図３における端子部１２ａの長さが短くなる。したがって、コネクタの低背化が容易に可能である。   In addition, since the first bending scheduled portion 31 is provided in the second straight line portion 27 (in the middle of the first offset portion 26 and the second offset portion 28), as a result, the first bending scheduled portion 31 is provided. The distance from the portion 31 to the free end, that is, the length of the terminal portion 12a in FIG. Therefore, it is possible to easily reduce the height of the connector.

図６及び図７を参照すると、上述したコンタクト群の製造に使用される中間部材の他例としてのリードフレーム２０′が示されている。図４及び図５と同様な部分については、同じ参照符号を付して説明を省略する。   Referring to FIGS. 6 and 7, a lead frame 20 ′ as another example of an intermediate member used for manufacturing the contact group described above is shown. Parts similar to those in FIGS. 4 and 5 are denoted by the same reference numerals and description thereof is omitted.

このリードフレーム２０′においては、第１の折曲予定部３１を第１の直線部２５に設けている。具体的には、第１の折曲予定部３１が第１のオフセット部２６と連結部２４との間でかつ第１のオフセット部２６に隣接して設けられている。第１の折曲予定部３１の位置を変更した関係で、第２の折曲予定部３２及び付加折曲予定部３３の位置が少し連結部２４に近づいた位置に設けられているが、本質的な機能においては図４に示したリードフレーム２０と同等である。   In the lead frame 20 ′, the first scheduled bending portion 31 is provided in the first straight portion 25. Specifically, the first scheduled bending portion 31 is provided between the first offset portion 26 and the connecting portion 24 and adjacent to the first offset portion 26. Although the position of the 2nd bending plan part 32 and the additional bending plan part 33 is provided in the position which approached the connection part 24 a little by the relationship which changed the position of the 1st bending plan part 31, essence The typical function is the same as that of the lead frame 20 shown in FIG.

このリードフレーム２０′は、図４のリードフレーム２０に比べて第１の折曲予定部３１から自由端までの距離、即ち、図３における端子部１２ａの長さが少し長くなるが、その他については図５のリードフレーム２０と同等な作用効果を奏する。   Compared with the lead frame 20 of FIG. 4, the lead frame 20 'has a slightly longer distance from the first bent portion 31 to the free end, that is, the length of the terminal portion 12a in FIG. Produces the same effects as the lead frame 20 of FIG.

リードフレーム２０、２０′のいずれにおいても、図１及び図２に示すようにプリント基板１１とほぼ同等な平面上に配置されるタイプのコネクタの場合には、付加折曲予定部３３は各リードに２箇所ずつ設けられるが、本発明は引用文献１のようにプリント基板１１の上面に搭載されるタイプのコネクタとしても実施可能であり、後者の場合には付加折曲予定部３３は不要である。   In both of the lead frames 20 and 20 ', in the case of a connector of a type arranged on a plane substantially equivalent to the printed circuit board 11 as shown in FIGS. However, the present invention can also be implemented as a connector of the type mounted on the upper surface of the printed circuit board 11 as in the cited document 1, and in the latter case, the additional bending scheduled portion 33 is unnecessary. is there.

なお、本発明は上記実施形態に限られることはなく、またその一部又は全部は以下の付記のようにも記載され得るがそれらには限られない。   In addition, this invention is not limited to the said embodiment, The one part or all part can also be described like the following additional remarks, but it is not restricted to them.
