Description

本発明は、導電性のコンタクトをシールドするシールド部材及び電気コネクタに関する。   The present invention relates to a shield member and an electrical connector for shielding a conductive contact.

近年、電気コネクタには、導電性のコンタクトに対する高いシールド性能の要求が高まっており、コンタクトからのノイズを遮蔽するためにシールド部材が設けられている。かかるシールド部材は、基板のグランドに接続するものであり、導電性に優れている等の理由により、亜鉛やアルミニウムを使用したダイカストにより形成されている(例えば、特許文献1)。   In recent years, electrical connectors have been required to have high shielding performance for conductive contacts, and a shield member is provided to shield noise from the contacts. Such a shield member is connected to the ground of the substrate, and is formed by die casting using zinc or aluminum for reasons such as excellent conductivity (for example, Patent Document 1).

図14から図16を参照しながら、従来の電気コネクタ及びその電気コネクタに取り付けられるシールド部材について、具体的に説明する。図14は、従来の電気コネクタ100の正面図であり、図15は、従来の電気コネクタ100の斜視図であり、図16は、従来のシールド部材130の斜視図である。   A conventional electrical connector and a shield member attached to the electrical connector will be specifically described with reference to FIGS. 14 is a front view of a conventional electrical connector 100, FIG. 15 is a perspective view of the conventional electrical connector 100, and FIG. 16 is a perspective view of a conventional shield member 130.

従来のシールド部材130は、筒形状の本体部133と、本体部133の後方に設けられる裾部134と、本体部133と裾部134とを連結する連結部132と、裾部134の後端から後方に延設される脚部131と、から構成されている。   The conventional shield member 130 includes a cylindrical main body portion 133, a skirt portion 134 provided behind the main body portion 133, a connecting portion 132 that connects the main body portion 133 and the skirt portion 134, and a rear end of the hem portion 134. Leg portion 131 extending rearward from the rear.

従来の電気コネクタ100は、図15に示すように、ハウジング110の後端面から突出するコンタクト120の端子部121の周囲を、シールド部材130の脚部131で囲む構成を有している。本体部133は、コンタクト120の電気的特性を低下させないように、各接続部122から所定距離r10だけ離れた位置で接続部122の周囲を囲んでいる。また、脚部131は、基板のグランドと接続するものであり、端子部121が接続する基板の導電部と干渉しない基板の位置にグランドを形成する必要があるため、端子部121からある程度離して配置されるように構成されている。これにより、裾部134は、本体部133よりも大きく形成されるため、連結部132を介して本体部133と連結される。   As shown in FIG. 15, the conventional electrical connector 100 has a configuration in which the periphery of the terminal portion 121 of the contact 120 protruding from the rear end surface of the housing 110 is surrounded by the leg portion 131 of the shield member 130. The main body portion 133 surrounds the connection portion 122 at a position separated from each connection portion 122 by a predetermined distance r10 so as not to deteriorate the electrical characteristics of the contact 120. Further, the leg portion 131 is connected to the ground of the substrate, and it is necessary to form the ground at a position on the substrate that does not interfere with the conductive portion of the substrate to which the terminal portion 121 is connected. It is configured to be arranged. Thereby, the skirt part 134 is formed larger than the main body part 133, and is thus connected to the main body part 133 via the connection part 132.

かかる連結部132は、図14に示すように、嵌合部111の内底面112に当接することにより、シールド部材130の後方への抜け止めになっている。また、連結部132は、相手側コネクタの嵌合方向における低背化のため、及び嵌合部111の内底面112にガタツキなく安定して保持されるように、平坦になっている。更に、連結部132は、嵌合部111に嵌合する相手側コネクタの嵌合部の径と、脚部131の配設と、に応じて、径方向に所定の長さr11に亘って平坦になっている。   As shown in FIG. 14, the connecting portion 132 is in contact with the inner bottom surface 112 of the fitting portion 111 to prevent the shield member 130 from coming off backward. Further, the connecting portion 132 is flat so as to reduce the height in the fitting direction of the mating connector and to be stably held on the inner bottom surface 112 of the fitting portion 111 without rattling. Furthermore, the connecting portion 132 is flat over a predetermined length r11 in the radial direction in accordance with the diameter of the fitting portion of the mating connector that fits into the fitting portion 111 and the arrangement of the leg portion 131. It has become.

また、近年、電気コネクタを搭載する電子機器に対しては、小型化の要求が高まっており、電子機器に搭載される電気コネクタに対しても小型化の要求が高まっている。   In recent years, there has been an increasing demand for miniaturization of electronic devices equipped with electrical connectors, and there has been an increasing demand for miniaturization of electrical connectors mounted on electronic devices.

しかしながら、従来のシールド部材及び電気コネクタにおいては、シールド部材の連結
部を径方向に所定の長さr11に亘って平坦に形成するため、シールド部材の裾部の径が必要以上に大きくなって小型化することが困難であるという課題を有する。また、従来のシールド部材及び電気コネクタにおいては、裾部が大きくなることに伴って、端子部が接続する基板の導電部と干渉しない位置よりも更に導電部から離れた基板の位置に、シールド部材が接続するグランドを設けることとなり、基板に対する実装面積の増大を招くという課題を有する。
However, in the conventional shield member and electrical connector, since the connecting portion of the shield member is formed flat over the predetermined length r11 in the radial direction, the diameter of the skirt portion of the shield member becomes larger than necessary and is small. It has the subject that it is difficult to make it. Further, in the conventional shield member and electrical connector, as the skirt portion becomes larger, the shield member is located at a position on the board further away from the conductive part than the position where the terminal part does not interfere with the conductive part of the board to be connected. Is provided with a ground to be connected, which causes a problem of increasing the mounting area on the substrate.

シールド部材30は、本体部31と、裾部32と、脚部33と、連結部34と、を備えている。シールド部材30は、金属板を絞り加工を含めたプレス加工して形成されている。シールド部材30は、バネ性を有する材料により形成され、典型的にはステンレスにより形成されている。シールド部材30は、連結部34及び裾部32を形成する前に予め施された金属メッキ処理により形成された金属メッキ層のみで覆われており、典型的にはプレス加工前の金属板の主面に予め施された金属メッキ処理により形成された金属メッキ層のみで覆われている。本実施形態では、プレス加工後に金属メッキ処理を施さないので、シールド部材30の金属板の破断面に対応する部分は金属メッキ層で覆われていない。ここで、金属メッキは、典型的には下地のニッケルメッキの上に、半田付け性を良好にするために錫メッキされた二層になっている。   The shield member 30 includes a main body portion 31, a skirt portion 32, a leg portion 33, and a connecting portion 34. The shield member 30 is formed by pressing a metal plate including drawing. The shield member 30 is made of a material having a spring property, and is typically made of stainless steel. The shield member 30 is covered only with a metal plating layer formed by a metal plating process performed in advance before forming the connecting portion 34 and the skirt portion 32, and is typically the main plate of the metal plate before press working. The surface is covered only with a metal plating layer formed by a metal plating process applied in advance. In the present embodiment, since the metal plating process is not performed after the press working, the portion corresponding to the fracture surface of the metal plate of the shield member 30 is not covered with the metal plating layer. Here, the metal plating is typically two layers tin-plated on top of the underlying nickel plating to improve solderability.

本体部31は、板状であり、前方を外部に開放した中空孔35を内部に備え、周方向の全周にわたって切れ目なく連続して形成された筒形状である。本体部31は、前方から見て軸心P1を中心とする円状になっている。本体部31は、複数の保持部7の各々に内壁を当接し、コンタクト20の接続部21の周囲を、接続部21から所定距離r2だけ離間した状態で覆っている。   The main body 31 is plate-shaped and has a hollow hole 35 that is open frontward to the outside, and has a cylindrical shape that is continuously formed over the entire circumference in the circumferential direction. The main body 31 has a circular shape centered on the axis P1 when viewed from the front. The main body portion 31 abuts the inner wall of each of the plurality of holding portions 7 and covers the periphery of the connection portion 21 of the contact 20 in a state of being separated from the connection portion 21 by a predetermined distance r2.

裾部32は、板状であり、後方を外部に開放すると共に中空孔35と連通する中空孔36を内部に備え、本体部31の径よりも大径であって本体部31と同軸の筒形状である。裾部32は、後方から見て軸心P1を中心とする円状に形成されている。裾部32には、脚部33の間の後端から後方に延設された板状の突出部321が設けられている。突出部321は、後端が脚部33の係止爪331の前端と左右に並ぶように設けられている(図9参照)。裾部32は、ハウジング10の台座部17の溝部18に係合している。裾部32の軸心P1と平行な方向の長さH(図9参照)(以下、「長さH」と記載)は、所定の範囲になっている。ここで、軸心P1は、同軸である本体部31と裾部32との軸である。なお、長さHの範囲については、後述する。   The skirt portion 32 is plate-shaped, and has a hollow hole 36 that opens to the outside and communicates with the hollow hole 35. The skirt portion 32 has a diameter larger than that of the main body portion 31 and is coaxial with the main body portion 31. Shape. The skirt portion 32 is formed in a circular shape centered on the axis P1 when viewed from the rear. The skirt portion 32 is provided with a plate-like protruding portion 321 extending rearward from the rear end between the leg portions 33. The protruding portion 321 is provided so that the rear end thereof is aligned with the front end of the locking claw 331 of the leg portion 33 (see FIG. 9). The skirt portion 32 is engaged with the groove portion 18 of the base portion 17 of the housing 10. A length H (see FIG. 9) in the direction parallel to the axis P1 of the skirt 32 (hereinafter referred to as “length H”) is within a predetermined range. Here, the axis P <b> 1 is an axis of the body portion 31 and the skirt portion 32 that are coaxial. The range of the length H will be described later.

脚部33は、筒形状の裾部32の周方向を板幅方向とする板状であり、裾部32の周方向に所定間隔で設けられていると共に、裾部32より後方に延設されて台座部17の貫通孔12を貫通して台座部17より後方に突出している。脚部33は、左右両側に係止爪331を有している。脚部33は、複数設けられ、端子部22の外周において本体部31及び裾部32の軸心Pを中心とする円の同一円周上に所定間隔で配置されている。   The leg portions 33 have a plate shape in which the circumferential direction of the cylindrical hem portion 32 is the plate width direction, are provided at predetermined intervals in the circumferential direction of the hem portion 32, and extend rearward from the hem portion 32. Through the through hole 12 of the pedestal 17 and protrudes rearward from the pedestal 17. The leg portion 33 has locking claws 331 on both the left and right sides. A plurality of leg portions 33 are provided, and are arranged at predetermined intervals on the same circumference of a circle centering on the axis P of the main body portion 31 and the bottom portion 32 on the outer periphery of the terminal portion 22.

連結部34は、板状であり、本体部31と裾部32とを連結し、段差を形成している。連結部34は、挿入孔11に挿入されて嵌合する相手側コネクタの図示しない嵌合部の径に応じて、径方向に所定の長さr3に亘って平坦になっており(図4参照)、環状凹部19の平坦な内底面に当接して配置されることにより(図6参照)、シールド部材30の後方への抜け止めになっていると共に、環状凹部19の内底面にガタツキなく安定して保持される。なお、径方向の長さr3は、相手側コネクタの嵌合部の径に応じて変えることができる。   The connecting portion 34 has a plate shape and connects the main body portion 31 and the skirt portion 32 to form a step. The connecting portion 34 is flat over a predetermined length r3 in the radial direction according to the diameter of the fitting portion (not shown) of the mating connector that is inserted into the insertion hole 11 and fits (see FIG. 4). ) By being in contact with the flat inner bottom surface of the annular recess 19 (see FIG. 6), the shield member 30 is prevented from coming out backward, and the inner bottom surface of the annular recess 19 is stable without rattling. Held. The radial length r3 can be changed according to the diameter of the mating portion of the mating connector.

連結部34と本体部31との接続部37は、所定の最小曲率半径以上の曲率半径で湾曲した外縁を有している。また、連結部34と裾部32との接続部38は、所定の最小曲率半径以上の曲率半径で湾曲した内縁を有している。ここで、外縁とは、シールド部材30の外側の輪郭に沿った縁である。また、内縁とは、シールド部材30の内側の輪郭に沿った縁である。なお、接続部37の外縁の曲率半径の範囲及び接続部38の内縁の曲率半径の範囲については、後述する。   The connection part 37 between the coupling part 34 and the main body part 31 has an outer edge that is curved with a curvature radius that is equal to or greater than a predetermined minimum curvature radius. Further, the connecting portion 38 between the connecting portion 34 and the skirt portion 32 has an inner edge that is curved with a radius of curvature equal to or greater than a predetermined minimum radius of curvature. Here, the outer edge is an edge along the outer contour of the shield member 30. The inner edge is an edge along the inner contour of the shield member 30. The range of the radius of curvature of the outer edge of the connecting portion 37 and the range of the radius of curvature of the inner edge of the connecting portion 38 will be described later.

シールド部材30を後方から見た際における、シールド部材30の軸心P1からの半径r1(図10参照)は、従来のシールド部材130を後方から見た際における、シールド部材130の軸心からの最大半径より小さいので、シールド部材30を従来に比べて小型化することができ、シールド部材30を組み込んだ電気コネクタ1も従来に比べて小型化することができる。   When the shield member 30 is viewed from the rear, the radius r1 (see FIG. 10) from the axis P1 of the shield member 30 is from the axis of the shield member 130 when the conventional shield member 130 is viewed from the rear. Since it is smaller than the maximum radius, the shield member 30 can be reduced in size compared to the conventional one, and the electrical connector 1 incorporating the shield member 30 can also be reduced in size compared to the conventional one.

また、電気コネクタ1は、筒形状の裾部32の円周方向を板幅方向とする板状の脚部33によりコンタクト20の端子部22を覆うので、脚部33により端子部22を十分に覆うことができ、コンタクト20に対するシールド性能を向上させることができる。   In addition, since the electrical connector 1 covers the terminal portion 22 of the contact 20 with the plate-like leg portion 33 in which the circumferential direction of the cylindrical skirt portion 32 is the plate width direction, the terminal portion 22 is sufficiently covered by the leg portion 33. The shielding performance against the contact 20 can be improved.

また、裾部32の円周方向を板幅方向とする脚部33を、その円周方向に所定間隔で複数設けたことにより、端子部22と接続する基板の導電部から引き回されるパターンを、脚部33の間を通して配線することにより、基板のパターンの引き回しに影響を与えることなく、シールド性能を向上させることができる。特に、脚部33の裾部32の円周方向における間隔を基板の導電部から引き回されるパターンの幅と一致させることにより、高いシールド性能を得ることと、基板のパターンの引き回しの自由度の確保と、を両立させることができる。   Further, by providing a plurality of leg portions 33 with the circumferential direction of the skirt portion 32 in the plate width direction at a predetermined interval in the circumferential direction, a pattern drawn from the conductive portion of the substrate connected to the terminal portion 22 By wiring between the legs 33, the shield performance can be improved without affecting the routing of the pattern of the substrate. In particular, it is possible to obtain a high shielding performance by matching the interval in the circumferential direction of the skirt 32 of the leg portion 33 with the width of the pattern routed from the conductive portion of the substrate, and the degree of freedom in routing the pattern of the substrate. Ensuring both of these.

<シールド部材の製造方法>
本発明の実施形態に係るシールド部材30の製造方法につき、図13を参照しながら、以下に詳細に説明する。なお、図13(a)及び図13(b)の各々において、上図は板状部材50を後方から見た図であり、下図は板状部材50を側方から見た図である。
<Method for manufacturing shield member>
The manufacturing method of the shield member 30 according to the embodiment of the present invention will be described in detail below with reference to FIG. In each of FIGS. 13 (a) and 13 (b), the upper view is a view of the plate member 50 as viewed from the rear, and the lower view is a view of the plate member 50 as viewed from the side.

まず、予め金属メッキ処理により金属メッキ層を形成した金属製の板状部材50の一部を打ち抜いて、板状部材50の板厚方向に円弧状に貫通する複数の円弧状孔53を形成することにより、円形部51と、円形部51の外縁部から放射状に延設されると共に延設方向の端部54が板状部材50に接続する複数の放射状片52と、を形成する(図13(a))。放射状片52は、円形部51の中心に対して等角度間隔で放射状に延設されている。円弧状孔53を形成する際に生じた円形部51の破断面及び放射状片52の破断面は、金属メッキ層により覆われていない。   First, a part of a metal plate-like member 50 on which a metal plating layer has been previously formed by metal plating is punched out to form a plurality of arc-shaped holes 53 penetrating in an arc shape in the plate thickness direction of the plate-like member 50. Thus, the circular portion 51 and a plurality of radial pieces 52 that extend radially from the outer edge portion of the circular portion 51 and whose end portions 54 in the extending direction are connected to the plate-like member 50 are formed (FIG. 13). (A)). The radial pieces 52 extend radially at equal angular intervals with respect to the center of the circular portion 51. The fracture surface of the circular portion 51 and the fracture surface of the radial piece 52 generated when the arc-shaped hole 53 is formed are not covered with the metal plating layer.

次に、円形部51の外側部を上部ダイ61と下部ダイ62とで上下から挟持した状態で、円形部51の中央を、パンチ60でダイ孔の内壁63に沿って絞り加工することにより、本体部31を形成すると共に、本体部31の周囲に鍔部55を形成する。この際、同時に、放射状片52は、幅が狭くなるように打ち抜かれる。(図13(b))。なお、打ち抜かれた放射状片52の側壁部は、金属メッキ層により覆われていない。   Next, by drawing the center of the circular portion 51 along the inner wall 63 of the die hole with the punch 60 in a state where the outer portion of the circular portion 51 is sandwiched from above and below by the upper die 61 and the lower die 62, The body portion 31 is formed, and the flange portion 55 is formed around the body portion 31. At the same time, the radial piece 52 is punched out so as to be narrow. (FIG. 13B). The punched radial piece 52 is not covered with a metal plating layer.

次に、本体部31の絞り方向(図13(b)の上図において紙面に対して手前から奥に向かう方向)の先端の天面56を抜いて本体部31の内部を絞り方向に向けて外部に開放する。   Next, the top surface 56 at the tip of the main body 31 in the drawing direction (the direction from the front to the back in FIG. 13B) is pulled out so that the inside of the main body 31 faces the drawing direction. Open to the outside.

次に、放射状片52の端部54を板状部材50より切断(図13(b)のS1で切断)する(図13(c))。端部54の切断面は、金属メッキ層により覆われていない。   Next, the edge part 54 of the radial piece 52 is cut | disconnected from the plate-shaped member 50 (it cut | disconnects by S1 of FIG.13 (b)) (FIG.13 (c)). The cut surface of the end 54 is not covered with the metal plating layer.

次に、鍔部55の外周側部55a(図13(c)のS2よりも外側の部分)を絞り方向(図13(c)の紙面に対して手前から奥に向かう方向)と反対方向に折り曲げることにより、外周側部55aを本体部31と同軸であって本体部31よりも大径の筒形状の裾部32とし、鍔部55の外周側部55aよりも内側の内周側部55b(図13(c)のS2よりも内側の部分)を本体部31と裾部32とを連結する連結部34とすると共に、放射状片52を裾部32から絞り方向と反対方向に延設された脚部33とする(図13(d))。この際、連結部34と本体部31との接続部37の外縁を所定の最小曲率半径以上の曲率半径で湾曲させると共に、連結部34と裾部32との接続部38の内縁を所定の最小曲率半径以上の曲率半径で湾曲させる。これにより、接続部37及び接続部38において金属メッキ層の金属メッキの剥離を生じないようにすることができる。また、長さHを所定の範囲に設定することにより、折り曲げる箇所の周辺を押さえるしわ押さえ用の部品を有さない簡素な金型を用いて、鍔部55の外周側部55aを折り曲げることができる。ここで、板状部材50を折り曲げる、とは、上述した本体部31を形成するために施される絞り加工の場合のように上部ダイ61と下部ダイ62とで板状部材50を挟持することなく板状部材50を折り曲げることを指す。   Next, the outer peripheral side portion 55a (the portion outside S2 in FIG. 13C) of the flange portion 55 is set in the direction opposite to the drawing direction (the direction from the front to the back with respect to the paper surface in FIG. 13C). By bending, the outer peripheral side portion 55a is coaxial with the main body portion 31 and has a cylindrical skirt 32 having a larger diameter than the main body portion 31, and the inner peripheral side portion 55b inside the outer peripheral side portion 55a of the flange portion 55. The portion (inside of S2 in FIG. 13C) is a connecting portion 34 that connects the main body 31 and the skirt 32, and the radial piece 52 is extended from the skirt 32 in the direction opposite to the squeezing direction. It is set as the leg part 33 (FIG.13 (d)). At this time, the outer edge of the connecting portion 37 between the connecting portion 34 and the main body portion 31 is curved with a radius of curvature greater than or equal to a predetermined minimum curvature radius, and the inner edge of the connecting portion 38 between the connecting portion 34 and the skirt portion 32 is set to a predetermined minimum radius. Curve with a radius of curvature greater than the radius of curvature. Thereby, it is possible to prevent the metal plating layer from peeling off at the connection portion 37 and the connection portion 38. In addition, by setting the length H within a predetermined range, the outer peripheral side portion 55a of the flange portion 55 can be bent using a simple mold that does not have a wrinkle holding part that holds the periphery of the portion to be bent. it can. Here, the bending of the plate-like member 50 means that the plate-like member 50 is sandwiched between the upper die 61 and the lower die 62 as in the case of the drawing process performed to form the main body portion 31 described above. It means that the plate member 50 is bent.

図13(d)の状態の加工品は、プレス加工前の板状部材50の主面に予め施された金属メッキ処理により形成された金属メッキ層のみで覆われている。なお、図13(d)の状態の加工品を、溶融した金属メッキを溜めた金属メッキ槽に浸して金属メッキする、いわゆる、後メッキ処理を施してもよいが、本実施形態においては、後述する通り、板状部材50に形成した金属メッキ層が剥離していないので、この後メッキ処理を省略している。これにより、シールド部材30に対する後メッキ処理を不要にすることができるので、シールド部材30を容易に製造することができる。   The processed product in the state of FIG. 13D is covered only with a metal plating layer formed by a metal plating process previously applied to the main surface of the plate-like member 50 before pressing. The processed product in the state of FIG. 13 (d) may be subjected to a so-called post-plating treatment in which metal plating is performed by immersing it in a metal plating tank storing molten metal plating. As described above, since the metal plating layer formed on the plate-like member 50 is not peeled off, the subsequent plating process is omitted. Thereby, since the post-plating process with respect to the shield member 30 can be made unnecessary, the shield member 30 can be manufactured easily.

このように、シールド部材30を金属製の板材より形成することにより、本体部31、
裾部32及び脚部33を板状に形成することができ、シールド部材30及び電気コネクタ1全体を、小型化及び軽量化することができると共に、低コストで製造することができる。
Thus, by forming the shield member 30 from a metal plate material, the main body 31,
The skirt portion 32 and the leg portion 33 can be formed in a plate shape, and the shield member 30 and the entire electrical connector 1 can be reduced in size and weight, and can be manufactured at low cost.

また、シールド部材30の裾部32を板状にして薄型化し、裾部32を台座部17の溝部18に保持させるので、ハウジング10を小さくすることができる。   Further, since the bottom portion 32 of the shield member 30 is formed into a plate shape and is thinned, and the bottom portion 32 is held in the groove portion 18 of the pedestal portion 17, the housing 10 can be made small.

また、本体部31を周方向の全周にわたって切れ目なく連続して形成された筒形状にするので、本体部31の周方向に生じた隙間から不要輻射が放出されることによる電気遮蔽性能の低下を防ぐことができる。本体部31の周方向に生じる隙間は、板材を折り曲げ加工することによって本体部を形成する場合において、本体部の周方向における板材の一方の端部と他方の端部とを接合する際に生じる。本実施形態では、本体部31を絞り加工で形成することにより、上記の隙間を無くすることができる。   Moreover, since the main body part 31 is formed into a cylindrical shape that is continuously formed over the entire circumference in the circumferential direction, the electric shielding performance is deteriorated by unnecessary radiation being emitted from the gap generated in the circumferential direction of the main body part 31. Can be prevented. The gap generated in the circumferential direction of the main body 31 is generated when the one end and the other end of the plate in the circumferential direction of the main body are joined when the main body is formed by bending the plate. . In the present embodiment, the gap can be eliminated by forming the main body 31 by drawing.

<電気コネクタの組み立て方法>
本発明の実施形態に係る電気コネクタ1の組み立て方法につき、以下に詳細に説明する。
<Assembly method of electrical connector>
The method for assembling the electrical connector 1 according to the embodiment of the present invention will be described in detail below.

まず、ハウジング10の貫通孔13に対して、コンタクト20を接続部21が端子部22より前方になるようにした状態で後方より挿入する。   First, the contact 20 is inserted into the through hole 13 of the housing 10 from the rear with the connection portion 21 positioned in front of the terminal portion 22.

次に、接続部21の固定部23との接続部近辺及び固定部23がハウジング10の図示しない固定部に圧入され、コンタクト20がハウジング10に固定される。この状態において、固定部23は、前端が台座部17の圧入箇所に当接してコンタクト20の前方への移動を規制し、これにより接続部21は挿入孔11の内部で所定量突出して挿入孔11に配置され、端子部22は台座部17の貫通孔13から後方に突出する。   Next, the vicinity of the connecting portion of the connecting portion 21 with the fixing portion 23 and the fixing portion 23 are press-fitted into a fixing portion (not shown) of the housing 10, and the contact 20 is fixed to the housing 10. In this state, the front end of the fixing portion 23 abuts against the press-fitted portion of the pedestal portion 17 and restricts the forward movement of the contact 20, whereby the connection portion 21 protrudes by a predetermined amount inside the insertion hole 11. 11, the terminal portion 22 protrudes rearward from the through hole 13 of the pedestal portion 17.

次に、挿入孔11に対して、上記の製造方法により製造したシールド部材30を、脚部33が本体部31より後方になるようにした状態で前方から挿入して脚部33を貫通孔12に貫通させる。   Next, the shield member 30 manufactured by the above manufacturing method is inserted into the insertion hole 11 from the front in a state where the leg portion 33 is located behind the main body portion 31, and the leg portion 33 is inserted into the through hole 12. To penetrate.

次に、シールド部材30の裾部32の後端が溝部18の後端に当接して、突出部321が溝部18に形成された凹部181に係合すると共に、シールド部材30の連結部34の後面が環状凹部19の内底面に当接することにより、シールド部材30の後方への移動が規制され、係止爪331が貫通孔12の内壁に圧入してシールド部材30がハウジング10に固定される。この状態において、本体部31により接続部21の周囲を覆うと共に、脚部33により端子部22の周囲を覆う。これにより、電気コネクタ1が完成する。   Next, the rear end of the skirt portion 32 of the shield member 30 abuts on the rear end of the groove portion 18 so that the protruding portion 321 engages with the concave portion 181 formed in the groove portion 18, and the connection portion 34 of the shield member 30 When the rear surface abuts against the inner bottom surface of the annular recess 19, the rearward movement of the shield member 30 is restricted, and the locking claw 331 is press-fitted into the inner wall of the through-hole 12 to fix the shield member 30 to the housing 10. . In this state, the body portion 31 covers the periphery of the connection portion 21, and the leg portion 33 covers the periphery of the terminal portion 22. Thereby, the electrical connector 1 is completed.

図11に示すように、突出部321を溝部18の凹部181に係合することにより、裾部32をハウジング10に強固に係合させることができるので、電気コネクタ1に相手側コネクタを接続する際等のシールド部材30に大きな負荷が加わるような場合であっても、脚部33の塑性変形を防ぐことができる。特に、シールド部材30に対して、軸心P1を中心として回転させるような方向(図11のJ方向)の力が外部より加わった場合に、突出部321の左右両端が凹部181の内壁に当接してシールド部材30のJ方向への移動を規制するので、脚部33に大きな負荷が加わって脚部33が塑性変形することを防ぐことができる。また、シールド部材30の裾部32を、板状部材50を打ち抜いた後に折り曲げて形成するので、突出部321を容易に形成することができる。   As shown in FIG. 11, the hem 32 can be firmly engaged with the housing 10 by engaging the protrusion 321 with the recess 181 of the groove 18, so that the mating connector is connected to the electrical connector 1. Even when a large load is applied to the shield member 30 at the time, the plastic deformation of the leg portion 33 can be prevented. In particular, when a force in a direction (J direction in FIG. 11) that rotates about the axis P1 is applied to the shield member 30 from the outside, the left and right ends of the protruding portion 321 abut against the inner wall of the recess 181. Since the shield member 30 is prevented from moving in the J direction in contact, it is possible to prevent the leg portion 33 from being plastically deformed by applying a large load to the leg portion 33. Moreover, since the skirt part 32 of the shield member 30 is formed by bending after punching the plate-like member 50, the protruding part 321 can be easily formed.

<接続部の外縁及び内縁の曲率半径の範囲>
本発明の第1の実施形態における接続部37の外縁、及び接続部38の内縁の曲率半径
の範囲につき、以下に詳細に説明する。
<Range of curvature radius of outer and inner edges of connecting part>
The range of the radius of curvature of the outer edge of the connecting portion 37 and the inner edge of the connecting portion 38 in the first embodiment of the present invention will be described in detail below.

接続部37の外縁及び接続部38の内縁の曲率半径が小さい場合、シールド部材30の表面全体を覆っている金属メッキ層の金属メッキが、接続部37又は接続部38において剥離する恐れがある。   When the curvature radius of the outer edge of the connection part 37 and the inner edge of the connection part 38 is small, the metal plating of the metal plating layer covering the entire surface of the shield member 30 may be peeled off at the connection part 37 or the connection part 38.

表1は、シールド部材30をステンレスで形成すると共に錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の錫メッキ層のメッキ厚が5μm及び板厚が0.2mmの場合における、接続部37の外縁の曲率半径Rを変化させた際の錫メッキの剥離の有無を調べたものである。   Table 1 shows that the shield member 30 is formed of stainless steel and tin-plated to form the outermost surface of the shield member 30 with a tin-plated layer, and the plating thickness of the tin-plated layer of the shield member 30 is 5 μm and the plate thickness is 0.1. In this case, the presence / absence of peeling of the tin plating when the radius of curvature R of the outer edge of the connecting portion 37 was changed was examined.

Figure 2016051577

接続部37は、表2の条件の場合、外縁の曲率半径Rが0.15mm以上(R≧0.15mm)であれば錫メッキの剥離を生じない。   In the case of the conditions in Table 2, the connecting portion 37 does not peel off the tin plating if the radius of curvature R of the outer edge is 0.15 mm or more (R ≧ 0.15 mm).

接続部37は、表3の条件の場合、外縁の曲率半径Rが0.25mm以上(R≧0.25mm)であれば錫メッキの剥離を生じない。   In the case of the conditions in Table 3, the connecting portion 37 does not peel off the tin plating if the radius of curvature R of the outer edge is 0.25 mm or more (R ≧ 0.25 mm).

表1から表3より、接続部37の外縁の曲率半径Rは、シールド部材30をステンレスで形成すると共に錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の錫メッキ層のメッキ厚を5μmとした場合、シールド部材30の板厚の2分の1以上であれば錫メッキの剥離を生じない。表1から表3の結果は、接続部38の内縁の曲率半径Rについても同様である。従って、接続部37の外縁の曲率半径R及び接続部38の内縁の曲率半径Rの各々は、シールド部材30の錫メッキ層のメッキ厚を5μmとした場合、シールド部材30の板厚の2分の1以上であることが好ましい。   From Table 1 to Table 3, the radius of curvature R of the outer edge of the connecting portion 37 is such that the shield member 30 is formed of stainless steel and tin-plated to form the outermost surface of the shield member 30 with a tin plating layer. When the plating thickness of the tin plating layer is 5 μm, the tin plating does not peel off as long as it is at least half the plate thickness of the shield member 30. The results in Tables 1 to 3 are the same for the curvature radius R of the inner edge of the connection portion 38. Accordingly, the curvature radius R of the outer edge of the connection portion 37 and the curvature radius R of the inner edge of the connection portion 38 are each 2% of the plate thickness of the shield member 30 when the plating thickness of the tin plating layer of the shield member 30 is 5 μm. It is preferable that it is 1 or more.

また、接続部37の外縁及び接続部38の内縁の曲率半径Rを0.40mmより大きくした場合(R>0.40mm)、連結部34に平坦面を形成することができない。ここで、連結部34に平坦面を形成できなくなる接続部37の外縁の曲率半径Rの値及び接続部38の内縁の曲率半径Rの値の各々は、本体部31の外径と裾部32の外径との差、及びシールド部材30の板厚によって異なり、0.40mm以外になり得る。   Moreover, when the curvature radius R of the outer edge of the connection part 37 and the inner edge of the connection part 38 is made larger than 0.40 mm (R> 0.40 mm), a flat surface cannot be formed in the connection part 34. Here, the value of the radius of curvature R of the outer edge of the connecting portion 37 and the value of the radius of curvature R of the inner edge of the connecting portion 38 that cannot form a flat surface in the connecting portion 34 are respectively the outer diameter and the skirt portion 32 of the main body portion 31. Depending on the difference from the outer diameter of the shield member 30 and the plate thickness of the shield member 30, it may be other than 0.40 mm.

次に、表4は、シールド部材30をステンレスで形成すると共に錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の錫メッキ層のメッキ厚が10μm及び板厚が0.2mmの場合における、接続部37の外縁の曲率半径Rを変化させた際の錫メッキの剥離の有無を調べたものである。   Next, Table 4 shows that the shield member 30 is formed of stainless steel and tin-plated to form the outermost surface of the shield member 30 with a tin-plated layer. The tin-plated layer of the shield member 30 has a plating thickness of 10 μm and a plate thickness. In this case, the presence or absence of peeling of the tin plating when the radius of curvature R of the outer edge of the connecting portion 37 was changed was examined.

The tin-plated layer of the shield member 30 has a plating thickness of 10 μm and a plate thickness of 0.1. The presence or absence of peeling of the tin plating when the radius of curvature R of the outer edge of the connecting portion 37 was changed in the case of 3 mm was examined.

The tin-plated layer of the shield member 30 has a plating thickness of 10 μm and a plate thickness of 0.1. In the case of 5 mm, the presence or absence of peeling of the tin plating when the curvature radius R of the outer edge of the connecting portion 37 was changed was examined.

接続部37では、表6の条件の場合、全て錫メッキの剥離を生じた。   In the connection part 37, in the case of the conditions of Table 6, peeling of tin plating occurred.

表4から表6より、接続部37では、シールド部材30を錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の錫メッキ層のメッキ厚を10μmとした場合、全て錫メッキの剥離を生じた。表4から表6の結果は、接続部38の内縁部の曲率半径Rについても同様である。   From Table 4 to Table 6, in the connection part 37, when the shield member 30 is tin-plated and the outermost surface of the shield member 30 is formed by a tin-plated layer, and the plating thickness of the tin-plated layer of the shield member 30 is 10 μm , All caused peeling of the tin plating. The results in Tables 4 to 6 are the same for the curvature radius R of the inner edge portion of the connection portion 38.

また、接続部37の外縁及び接続部38の内縁の曲率半径Rを0.40mmより大きくした場合(R>0.40mm)、連結部34に平坦面を形成することができない。   Moreover, when the curvature radius R of the outer edge of the connection part 37 and the inner edge of the connection part 38 is made larger than 0.40 mm (R> 0.40 mm), a flat surface cannot be formed in the connection part 34.

上記より、シールド部材30を錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の錫メッキ層のメッキ厚を10μmとした場合、接続部37及び接続部38の各々においてメッキの剥離を生じて好ましくない。   From the above, when the shield member 30 is tin-plated to form the outermost surface of the shield member 30 with a tin-plated layer, and the plating thickness of the tin-plated layer of the shield member 30 is 10 μm, the connection portion 37 and the connection portion 38 In each case, peeling of the plating occurs, which is not preferable.

次に、表7は、シールド部材30をステンレスで形成すると共に錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の板厚を0.3mm、接続部37の外縁の曲率半径を0.15mmにした場合における、錫メッキ層のメッキ厚を変化させた際の錫メッキの剥離の有無を調べたものである。   Next, Table 7 shows that the shield member 30 is formed of stainless steel and tin-plated to form the outermost surface of the shield member 30 with a tin-plated layer. When the curvature radius of the outer edge was set to 0.15 mm, the presence or absence of peeling of the tin plating when the plating thickness of the tin plating layer was changed was examined.

Figure 2016051577
Figure 2016051577

接続部37は、表7の条件の場合、錫メッキ層のメッキ厚が2.5μm以上且つ5.0μm以下であれば錫メッキの剥離を生じない。また、金属メッキ層は、メッキ厚が薄いほど剥離し難い。表7の結果は、接続部38の内縁の曲率半径Rについても同様である。従って、表7より、接続部37の外縁の曲率半径R及び接続部38の内縁の曲率半径Rは、錫メッキ層のメッキ厚が5.0μm以下であれば錫メッキの剥離を生じないため好ましい。   In the case of the conditions in Table 7, the connecting portion 37 does not peel off the tin plating if the plating thickness of the tin plating layer is 2.5 μm or more and 5.0 μm or less. Further, the metal plating layer is more difficult to peel off as the plating thickness is thinner. The results in Table 7 are the same for the curvature radius R of the inner edge of the connecting portion 38. Therefore, from Table 7, the curvature radius R of the outer edge of the connection part 37 and the curvature radius R of the inner edge of the connection part 38 are preferable because the tin plating does not peel off if the plating thickness of the tin plating layer is 5.0 μm or less. .

このように、本実施形態によれば、接続部37の外縁及び接続部38の内縁の最小曲率半径を、シールド部材30の板厚の2分の1以上にすることにより、接続部37の外縁及び接続部38の内縁の最小曲率半径を板厚の2分の1まで小さくでき、本体部31と連結部34とのなす角度、及び連結部34と裾部32とのなす角度を垂直に近づけることができるので、本体部31及び裾部32の軸心方向に直交する方向に沿って連結部34を平坦に形成する場合に、筒形状である裾部32の径が必要以上に大きくなることを抑制することができ、小型化することができると共に、基板に対する実装面積の増大を抑制することができる。   As described above, according to the present embodiment, the outer edge of the connection portion 37 is set to be equal to or more than half the plate thickness of the shield member 30 by setting the minimum radius of curvature of the outer edge of the connection portion 37 and the inner edge of the connection portion 38. In addition, the minimum radius of curvature of the inner edge of the connecting portion 38 can be reduced to one half of the plate thickness, and the angle formed by the main body portion 31 and the connecting portion 34 and the angle formed by the connecting portion 34 and the skirt portion 32 are made close to vertical. Therefore, when the connecting portion 34 is formed flat along the direction orthogonal to the axial direction of the main body portion 31 and the bottom portion 32, the diameter of the cylindrical bottom portion 32 becomes larger than necessary. Can be suppressed, the size can be reduced, and an increase in mounting area with respect to the substrate can be suppressed.

また、本実施形態によれば、シールド部材30の表面を錫メッキすると共に錫メッキ層のメッキ厚を5μmにし、接続部37の外縁の曲率半径、及び接続部38の内縁の曲率半径を、シールド部材30の板厚の2分の1以上にすることにより、シールド部材の曲げ加工の際にメッキ剥離を生じることなく、一回の金属メッキ処理でシールド部材の表面全体を金属メッキ層で覆うことができ、製造工程を簡単にすることができ、製造コストを低減することができる。   Further, according to the present embodiment, the surface of the shield member 30 is tin-plated and the plating thickness of the tin-plated layer is 5 μm, and the curvature radius of the outer edge of the connection portion 37 and the curvature radius of the inner edge of the connection portion 38 are Covering the entire surface of the shield member with a metal plating layer by a single metal plating process without causing plating peeling during bending of the shield member by making the thickness of the member 30 more than half the plate thickness. The manufacturing process can be simplified and the manufacturing cost can be reduced.

また、本実施形態によれば、接続部37の外縁及び接続部38の内縁の曲率半径Rを0.40mm以下にするので、連結部34に平坦面を形成することができ、相手側コネクタの嵌合方向において低背化することができると共に、環状凹部19の内底面にガタツキなく安定してシールド部材30を保持することができる。   Further, according to the present embodiment, since the curvature radius R of the outer edge of the connecting portion 37 and the inner edge of the connecting portion 38 is 0.40 mm or less, a flat surface can be formed in the connecting portion 34, and the mating connector The height can be reduced in the fitting direction, and the shield member 30 can be stably held on the inner bottom surface of the annular recess 19 without rattling.

なお、上記の表1から表6では、シールド部材30を錫メッキしたが、シールド部材30を錫メッキよりも硬質であるために剥離し難いニッケルメッキした場合には、メッキの剥離に関して、少なくとも錫メッキした場合と同等以上の効果を得られる。   In Tables 1 to 6, the shield member 30 is tin-plated. However, when the shield member 30 is nickel-plated, which is harder than tin plating, it is difficult to peel off. An effect equivalent to or better than the case of plating can be obtained.

長さHは、表8の条件の場合、しわを生じないようにするためには0.9mm以下であることが好ましい。また、長さHは、板厚の3倍より小さい場合には板状部材50の金型への引っ掛かりが少なくなって折り曲げ加工が不可能となるため、板厚の3倍以上であることが好ましい。従って、長さHは、表8の条件の場合、0.6mm以上且つ0.9mm以下(0.6≦H≦0.9)であることが好ましい。   In the case of the conditions in Table 8, the length H is preferably 0.9 mm or less so as not to cause wrinkles. Further, when the length H is smaller than 3 times the plate thickness, the plate-like member 50 is hardly caught on the mold and cannot be bent. Therefore, the length H may be 3 times or more the plate thickness. preferable. Therefore, the length H is preferably 0.6 mm or more and 0.9 mm or less (0.6 ≦ H ≦ 0.9) under the conditions shown in Table 8.

表9は、シールド部材30をステンレスで形成すると共に錫メッキして錫メッキ層によりシールド部材30の最外表面を形成し、シールド部材30の錫メッキ層のメッキ厚が5μm、板厚が0.3mm、及び、接続部37の外縁及び接続部38の内縁の各々の曲率半径が0.15mmの場合における、長さHを変化させた際の、しわ押さえ用の部品を有しない金型を用いて折り曲げ加工した場合のしわの発生の有無を調べたものである。   Table 9 shows that the shield member 30 is made of stainless steel and tin-plated to form the outermost surface of the shield member 30 with a tin-plated layer. The tin-plated layer of the shield member 30 has a plating thickness of 5 μm and a plate thickness of 0.1. 3 mm, and a mold having no wrinkle holding part when the length H is changed when the curvature radius of each of the outer edge of the connecting portion 37 and the inner edge of the connecting portion 38 is 0.15 mm.

長さHは、表9の条件の場合、しわを生じないようにするためには1.5mm以下であることが好ましい。また、長さHは、板厚の3倍より小さい場合には板状部材50の金型への引っ掛かりが少なくなって折り曲げ加工が不可能となるため、板厚の3倍以上であることが好ましい。従って、長さHは、表9の条件の場合、0.9mm以上且つ1.5mm以下(0.9≦H≦1.5)であることが好ましい。   In the case of the conditions in Table 9, the length H is preferably 1.5 mm or less so as not to cause wrinkles. Further, when the length H is smaller than 3 times the plate thickness, the plate-like member 50 is hardly caught on the mold and cannot be bent. Therefore, the length H may be 3 times or more the plate thickness. preferable. Therefore, the length H is preferably 0.9 mm or more and 1.5 mm or less (0.9 ≦ H ≦ 1.5) under the conditions shown in Table 9.

The tin-plated layer of the shield member 30 has a plating thickness of 5 μm and a plate thickness of 0.1. 5 mm, and a mold having no wrinkle holding part when the length H is changed when the curvature radius of each of the outer edge of the connecting portion 37 and the inner edge of the connecting portion 38 is 0.15 mm.

長さHは、表10の条件の場合、しわを生じないようにするためには1.8mm以下であることが好ましい。また、長さHは、板厚の3倍より小さい場合には板状部材50の金型への引っ掛かりが少なくなって折り曲げ加工が不可能となるため、板厚の3倍以上であることが好ましい。従って、長さHは、表10の条件の場合、1.5mm以上且つ1.8
mm以下(1.5≦H≦1.8)であることが好ましい。
In the case of the conditions shown in Table 10, the length H is preferably 1.8 mm or less so as not to cause wrinkles. Further, when the length H is smaller than 3 times the plate thickness, the plate-like member 50 is hardly caught on the mold and cannot be bent. Therefore, the length H may be 3 times or more the plate thickness. preferable. Accordingly, the length H is 1.5 mm or more and 1.8 in the case of the conditions in Table 10.
It is preferable that it is mm or less (1.5 <= H <= 1.8).

また、シールド部材30を形成する材料、金属メッキの種類、メッキ厚、接続部37の外縁の曲率半径、及び、接続部38の内縁の曲率半径は、しわの発生に対して大きな影響を与えない。   Further, the material forming the shield member 30, the type of metal plating, the plating thickness, the radius of curvature of the outer edge of the connecting portion 37, and the radius of curvature of the inner edge of the connecting portion 38 do not significantly affect the generation of wrinkles. .

上記より、長さHは、シールド部材30の板厚を0.2mmとして、しわ押さえ用の部品を有しない金型を用いて折り曲げ加工した場合、板厚の3倍である0.6mm以上且つ0.9mm以下であることが好ましい。なお、長さHの下限値は、板状部材50の金型への引っ掛かりを作る等することができれば、0.6mmに限らず、0.6mmより小さくすることができる。   From the above, the length H is 0.6 mm or more, which is three times the plate thickness when the plate thickness of the shield member 30 is 0.2 mm and is bent using a mold having no wrinkle holding parts.

It is preferable that it is 2 mm or less. Note that the lower limit of the length H is not limited to 0.9 mm and can be made smaller than 0.9 mm as long as the plate member 50 can be caught on the mold.

また、長さHは、シールド部材30の板厚を0.5mmとして、しわ押さえ用の部品を有しない金型を用いて折り曲げ加工した場合、板厚の3倍である1.5mm以上且つ1.8mm以下であることが好ましい。なお、長さHの下限値は、板状部材50の金型への引っ掛かりを作る等することができれば、1.5mmに限らず、1.5mmより小さくすることができる。   The length H is 1.5 mm or more, which is three times the plate thickness when the plate thickness of the shield member 30 is 0.5 mm and is bent using a mold having no wrinkle holding parts. .8 mm or less is preferable. Note that the lower limit value of the length H is not limited to 1.5 mm and can be made smaller than 1.5 mm as long as the plate member 50 can be caught on the mold.

表8から表10より、シールド部材30の板厚が厚いほど、長さHを長くしてもしわを生じない。   From Table 8 to Table 10, as the plate thickness of the shield member 30 is thicker, wrinkles do not occur even if the length H is increased.

このように、本実施形態によれば、シールド部材30の板厚を0.2mmとして、裾部32の長さHを0.9mm以下にすることにより、折り曲げる箇所の周辺を押さえるしわ押さえ用の部品を有しない簡素な金型を用いて、板状部材50の折り曲げ部分におけるしわの発生などの支障なく板状部材50を折り曲げて裾部32を形成することができるので、板状部材50の折り曲げ箇所の周辺を上下から挟持して折り曲げ加工する必要をなくして製造工程を簡単にすることができ、製造コストを低減することができる。   Thus, according to the present embodiment, the thickness of the shield member 30 is 0.2 mm, and the length H of the skirt 32 is 0.9 mm or less, so that the area around the portion to be bent is pressed. Since the plate-like member 50 can be bent and the skirt portion 32 can be formed without hindrance such as generation of wrinkles in the bent portion of the plate-like member 50 using a simple mold having no parts. The manufacturing process can be simplified and the manufacturing cost can be reduced by eliminating the need to bend the periphery of the bent portion from above and below.

また、本実施形態によれば、シールド部材30の板厚を0.3mmとして、裾部32の長さHを1.2mm以下にすることにより、折り曲げる箇所の周辺を押さえるしわ押さえ用の部品を有しない簡素な金型を用いて、板状部材50の折り曲げ部分におけるしわの発生などの支障なく板状部材50を折り曲げて裾部32を形成することができるので、板状部材50の折り曲げ箇所の周辺を上下から挟持して折り曲げ加工する必要をなくして製造工程を簡単にすることができ、製造コストを低減することができる。   In addition, according to the present embodiment, the thickness of the shield member 30 is set to 0.3 mm, and the length H of the skirt portion 32 is set to 1.2 mm or less, whereby the wrinkle holding part that holds the periphery of the portion to be bent is provided. Since the plate-like member 50 can be bent to form the skirt portion 32 without hindrance such as generation of wrinkles in the bent portion of the plate-like member 50 by using a simple mold that does not have, the bent portion of the plate-like member 50 is bent. The manufacturing process can be simplified by eliminating the need to bend the periphery of the substrate from above and below, and the manufacturing cost can be reduced.

また、本実施形態によれば、シールド部材30の板厚を0.5mmとして、裾部32の長さHを1.8mm以下にすることにより、折り曲げる箇所の周辺を押さえるしわ押さえ用の部品を有しない簡素な金型を用いて、板状部材50の折り曲げ部分におけるしわの発生などの支障なく板状部材50を折り曲げて裾部32を形成することができるので、板状部材50の折り曲げ箇所の周辺を上下から挟持して折り曲げ加工する必要をなくして製造工程を簡単にすることができ、製造コストを低減することができる。   Further, according to the present embodiment, the thickness of the shield member 30 is set to 0.5 mm, and the length H of the skirt portion 32 is set to 1.8 mm or less, whereby the wrinkle holding component that holds the periphery of the portion to be bent is provided.
