This electrical connector will be described with reference to FIGS. 15 to 17 correspond to FIGS. 1, 2, and 4 of Patent Document 1 below, respectively. However, the reference numerals in the figure have been changed, and some of the reference numerals have been deleted.

両コネクタソケット９０５Ａ，９０５Ｂはプリント配線基板９０３の表面に配列されている。各コネクタソケット９０５Ａ，９０５Ｂはモールドコア９０５ａを有する。モールドコア９０５ａの外面は遮蔽シェル９０５ｃで覆われている。両コネクタソケット９０５Ａ，９０５Ｂは金属カバー９０６で覆われる。金属カバー９０６を介して、各コネクタソケット９０５Ａ，９０５Ｂの遮蔽シェル９０５ｃと、シャーシ等に固定される金属製の取付ブラケット９０１とが導通する。   Both connector sockets 905A and 905B are arranged on the surface of the printed wiring board 903. Each connector socket 905A, 905B has a mold core 905a. The outer surface of the mold core 905a is covered with a shielding shell 905c. Both connector sockets 905A and 905B are covered with a metal cover 906. Through the metal cover 906, the shielding shells 905c of the connector sockets 905A and 905B are electrically connected to the metal mounting bracket 901 fixed to the chassis or the like.

金属カバー９０６のアンカー片９０６ｄはプリント配線基板９０３のスロット９０７に挿入され、接地導体箔にはんだ付けされる。金属カバー９０６の頂部９０６ｅには折曲げ部９０８が曲げ成形されている（図１７参照）。折曲げ部９０８には、ブラケット側ばね片９０９、ソケット側ばね片９１０Ａ，９１０Ｂが切り起し成形されている。折曲げ部９０８を介して、取付ブラケット９０１と金属カバー９０６とが導通し、コネクタソケット９０５Ａ，９０５Ｂの遮蔽シェル９０５ｃと金属カバー９０６とが導通する。   The anchor piece 906d of the metal cover 906 is inserted into the slot 907 of the printed wiring board 903 and soldered to the ground conductor foil. A bent portion 908 is bent at the top portion 906e of the metal cover 906 (see FIG. 17). A bracket-side spring piece 909 and socket-side spring pieces 910A and 910B are cut and raised at the bent portion 908.

接続体７０は第１接触部７１と第２接触部７２とで構成される。第１接触部７１は第１背面部６４ａの他方の側端部（第１背面部６４ａの突合せ端部）に連なる。第１背面部６４ａの他方の側端部は第２背面部６４ｂ側の端部である。第１接触部７１はほぼＵ字形に折り曲げられている。第２接触部７２は第２背面部６４ｂの一方の側端部（第２背面部６４ｂの突合せ端部）に連なる。第２背面部６４ｂの一方の側端部は第１背面部６４ａ側の端部である。第２接触部７２はＵ字形に折り曲げられている。第１接触部７１と第２接触部７２とは高さ方向ＤＨでずれており、第１接触部７１は第２接触部７２の上に位置する。第１接触部７１と第２接触部７２とは、第１背面部６４ａと第２背面部６４ｂとに対してそれぞれほぼ直角に折り曲げられ、外部シェル６０の内方（前方）へ突出している。第２接触部７２の幅方向ＤＷの幅は第１接触部７１の幅方向ＤＷの幅よりも狭い（図３参照）。   The connection body 70 includes a first contact portion 71 and a second contact portion 72. The 1st contact part 71 continues to the other side edge part (butting edge part of the 1st back surface part 64a) of the 1st back surface part 64a. The other side end portion of the first back surface portion 64a is an end portion on the second back surface portion 64b side. The first contact portion 71 is bent in a substantially U shape. The second contact portion 72 continues to one side end portion of the second back surface portion 64b (a butting end portion of the second back surface portion 64b). One side end portion of the second back surface portion 64b is an end portion on the first back surface portion 64a side. The second contact portion 72 is bent into a U shape. The first contact portion 71 and the second contact portion 72 are displaced in the height direction DH, and the first contact portion 71 is located on the second contact portion 72. The first contact portion 71 and the second contact portion 72 are bent substantially at right angles to the first back surface portion 64a and the second back surface portion 64b, respectively, and project inward (frontward) of the outer shell 60. The width of the second contact portion 72 in the width direction DW is narrower than the width of the first contact portion 71 in the width direction DW (see FIG. 3).

外部ハウジング５０の上方から外部シェル６０を外部ハウジング５０に装着したとき、接続体７０の第１接触部７１及び第２接触部７２は、収容部５５ｃに挿入された２つの接触部４７間に入る。このとき、第２接触部７２の幅方向ＤＷの幅は第１接触部７１の幅方向ＤＷの幅よりも狭いので、第２接触部７２は隣接する２つの接触部４７の第１接点４７ｂ間をそれらに接触することなく通過する。第１接触部７１及び第２接触部７２が隣接する２つの接触部４７間に入ると、第１接触部７１は２つの内部シェル４０，４０のうちの一方の内部シェル４０の幅方向ＤＷの一方の側の接触部４７の第１接点４７ｂと他方の内部シェル４０の幅方向ＤＷの他方の側の接触部４７の第１接点４７ｂとによって挟まれ、第２接触部７２は一方の内部シェル４０の幅方向ＤＷの一方の側の接触部４７の第２接点４７ｃと他方の内部シェル４０の幅方向ＤＷの他方の側の接触部４７の第２接点４７ｃとによって挟まれる。その結果、２つの内部シェル４０と外部シェル６０とが接続体７０を介して導通する。   When the outer shell 60 is attached to the outer housing 50 from above the outer housing 50, the first contact portion 71 and the second contact portion 72 of the connection body 70 enter between the two contact portions 47 inserted into the housing portion 55c. . At this time, since the width in the width direction DW of the second contact portion 72 is narrower than the width in the width direction DW of the first contact portion 71, the second contact portion 72 is between the first contacts 47 b of the two adjacent contact portions 47. Pass through without touching them. When the first contact portion 71 and the second contact portion 72 enter between the two adjacent contact portions 47, the first contact portion 71 extends in the width direction DW of one of the two inner shells 40, 40. The first contact 47b of the contact portion 47 on one side and the first contact 47b of the contact portion 47 on the other side in the width direction DW of the other inner shell 40 are sandwiched between the second contact portion 72 and the one inner shell. The second contact 47c of the contact portion 47 on one side in the width direction DW of 40 and the second contact 47c of the contact portion 47 on the other side in the width direction DW of the other inner shell 40 are sandwiched. As a result, the two inner shells 40 and the outer shell 60 are conducted through the connection body 70.

また、２つの内部シェル４０の接続体７０を挟持する側の接触部４７とは反対側の接触部４７が、外部シェル６０に接触している。その結果、２つの内部シェル４０と外部シェル６０とが直接導通する。   Further, the contact portion 47 on the opposite side to the contact portion 47 on the side sandwiching the connection body 70 of the two inner shells 40 is in contact with the outer shell 60. As a result, the two inner shells 40 and the outer shell 60 are directly connected.

第１、第２背面部６４ａ，６４ｂの下端部にはそれぞれ下方へ向かって延びる第２接続部６７が連なる。第２接続部６７はプリント基板のスルーホールに挿入され、半田付けされる。   A second connection portion 67 extending downward is connected to the lower end portions of the first and second back surface portions 64a and 64b. The second connection portion 67 is inserted into the through hole of the printed board and soldered.

次に、外部シェル６０の製造方法を図５〜図１４に基づいて説明する。図５〜図１４はいずれも外部シェル６０の製造方法を説明するための概念図であり、第１接続部６５、第２接続部６７や接続体７０等の図示を省略した。   Next, a method for manufacturing the outer shell 60 will be described with reference to FIGS. 5 to 14 are conceptual diagrams for explaining the method of manufacturing the outer shell 60, and the first connection portion 65, the second connection portion 67, the connection body 70, and the like are not shown.

まず、図５に示すように、１つの平板な金属板を、外部シェル６０を展開したときの形状（所定の形状）に打ち抜く。打抜き直後の外部シェル６０では、一方の側面板６１、上面板６３、他方の側面板６１の順に、それらがＸ方向へ連なり、Ｘ方向と直交するＹ方向へ第１背面部６４ａが一方の側面板６１に連なり、Ｙ方向へ第２背面部６４ｂが上面板６３に連なる。第１背面部６４ａと第２背面部６４ｂとはＸ方向で所定距離（図２の第１背面部６４ａの幅方向ＤＷの寸法とほぼ同じか若干長い距離）だけ離れている。   First, as shown in FIG. 5, one flat metal plate is punched into a shape (predetermined shape) when the external shell 60 is developed. In the outer shell 60 immediately after punching, the one side plate 61, the top plate 63, and the other side plate 61 are arranged in this order in the X direction, and the first back surface portion 64a extends in the Y direction perpendicular to the X direction. The second back surface portion 64b is connected to the upper surface plate 63 in the Y direction. The first back surface portion 64a and the second back surface portion 64b are separated from each other by a predetermined distance in the X direction (a distance approximately equal to or slightly longer than the dimension in the width direction DW of the first back surface portion 64a in FIG. 2).

打抜き後、図６に示すように、板材を直角に曲げ加工する場合にはスプリングバックがあるため、第１背面部６４ａを一方の側面板６１に対してスプリングバック量を考慮してほぼ８５度（所定の角度）に折り曲げ、第１背面部６４ａが一方の側面板６１に対してスプリングバックによってほぼ直角の位置に復帰するまで放置する（第１背面部曲げ工程）。なお、後述する側面板曲げ工程、第２背面部曲げ工程においても、スプリングバック量を考慮した曲げ加工（いわゆるオーバーベンド）を行う。   After punching, as shown in FIG. 6, when the plate material is bent at a right angle, there is a spring back, so the first back surface portion 64a is approximately 85 degrees with respect to one side plate 61 in consideration of the amount of spring back. The first back surface portion 64a is bent (predetermined angle) until the first back surface portion 64a returns to a position substantially perpendicular to the one side plate 61 by a spring back (first back surface portion bending step). In the side plate bending process and the second back surface bending process, which will be described later, bending work (so-called overbending) is performed in consideration of the springback amount.

第１背面部曲げ工程後、図７、図８、図９、図１０に示すように、一方の側面板６１を上面板６３に対してほぼ８５度（所定の角度）に折り曲げ、一方の側面板６１が上面板６３に対してほぼ直角の位置に復帰するまで放置するとともに、他方の側面板６１を上面板６３に対してほぼ８５度（所定の角度）に折り曲げ、他方の側面板６１が上面板６３に対してほぼ直角の位置に復帰するまで放置する（側面板曲げ工程）。   After the first back surface bending step, as shown in FIGS. 7, 8, 9, and 10, one side plate 61 is bent to approximately 85 degrees (predetermined angle) with respect to the upper surface plate 63, and one side plate is bent. The face plate 61 is left until it returns to a position substantially perpendicular to the upper surface plate 63, and the other side surface plate 61 is bent to approximately 85 degrees (predetermined angle) with respect to the upper surface plate 63 so that the other side surface plate 61 It is left until it returns to a position substantially perpendicular to the upper surface plate 63 (side plate bending process).

側面板曲げ工程後、図１１、図１２、図１３、図１４に示すように、第２背面部６４ｂを上面板６３に対してほぼ８５度（所定の角度）に折り曲げ、第２背面部６４ｂが上面板６３に対してほぼ直角の位置に復帰するまで放置する（第２背面部曲げ工程）。上述の第１背面部６４ａ、両方の側面板６１、第２背面部６４ｂの曲げ加工は図示しないプレス機で行われ、加工方向はすべてＺ方向である。   After the side plate bending process, as shown in FIGS. 11, 12, 13, and 14, the second back surface portion 64b is bent at approximately 85 degrees (predetermined angle) with respect to the top surface plate 63, and the second back surface portion 64b. Is left until it returns to a position substantially perpendicular to the upper surface plate 63 (second back surface bending step). The above-described first back surface portion 64a, both side plates 61, and the second back surface portion 64b are bent by a pressing machine (not shown), and the processing directions are all in the Z direction.

以上の工程により、外部シェル６０が完成する。この製造方法では、側面板６１から延ばして形成された第１背面部６４ａを折り曲げ、その後上面板６３から延ばして形成された第２背面部６４ｂを折り曲げる。したがって、カム機構を備えた複雑な金型設備を用いなくとも、折曲げ加工時の第１背面部６４ａと第２背面部６４ｂとの干渉を回避でき、高いシールド性を持つ外部シェル６０の製造が可能になる。   The outer shell 60 is completed through the above steps. In this manufacturing method, the first back surface portion 64 a formed extending from the side plate 61 is bent, and then the second back surface portion 64 b formed extending from the top surface plate 63 is bent. Therefore, it is possible to avoid the interference between the first back surface portion 64a and the second back surface portion 64b during the bending process without using a complicated mold facility having a cam mechanism, and to manufacture the outer shell 60 having high shielding properties. Is possible.

次に、コネクタ１０の組立手順の一例を説明する。まず、内部ハウジング３０にコンタクト２０を組み付け、内部ハウジング３０の外周面に内部シェル４０を固定する（図２、図３参照）。その後、コンタクト２０及び内部シェル４０を組み付けた内部ハウジング３０を外部ハウジング５０の内部シェル挿入部５５ａに外部ハウジング５０の後方から挿入し、内部ハウジング３０を外部ハウジング５０に保持させる（図２参照）。   Next, an example of the assembly procedure of the connector 10 will be described. First, the contact 20 is assembled to the inner housing 30, and the inner shell 40 is fixed to the outer peripheral surface of the inner housing 30 (see FIGS. 2 and 3). Thereafter, the inner housing 30 assembled with the contact 20 and the inner shell 40 is inserted into the inner shell insertion portion 55a of the outer housing 50 from the rear side of the outer housing 50, and the inner housing 30 is held by the outer housing 50 (see FIG. 2).

外部ハウジング５０の幅方向ＤＷの左端に位置する内部シェル挿入部５５ａに挿入された内部シェル４０（図２において左端に位置する内部シェル４０）の右側の接触部４７は収容部５５ｃに、左側の接触部４７は左側の収容部５５ｄにそれぞれ挿入される。   The contact portion 47 on the right side of the inner shell 40 (inner shell 40 located on the left end in FIG. 2) inserted in the inner shell insertion portion 55a located on the left end in the width direction DW of the outer housing 50 is placed on the housing portion 55c. The contact portion 47 is inserted into the left receiving portion 55d.

外部ハウジング５０の幅方向ＤＷの右端に位置する内部シェル挿入部５５ａに挿入された内部シェル４０（図２において右端に位置する内部シェル４０）の左側の接触部４７は収容部５５ｃに、右側の接触部４７は右側の収容部５５ｄにそれぞれ挿入される。   The left contact portion 47 of the inner shell 40 (the inner shell 40 located at the right end in FIG. 2) inserted into the inner shell insertion portion 55a located at the right end in the width direction DW of the outer housing 50 is placed on the housing portion 55c. The contact portion 47 is inserted into the right accommodation portion 55d.

最後に、外部シェル６０を外部ハウジング５０に被せる。このとき、接続体７０を収容部５５ｃの上方から、幅方向ＤＷで隣接する２つの接触部４７間に挿入する。このとき、第２接触部７２の幅方向ＤＷの幅は第１接触部７１の幅方向ＤＷの幅よりも狭いので、第２接触部７２は隣接する接触部４７の第１接点４７ｂ間をそれらに接触することなく通過し得る。   Finally, the outer shell 60 is put on the outer housing 50. At this time, the connection body 70 is inserted between the two contact portions 47 adjacent in the width direction DW from above the accommodating portion 55c. At this time, since the width of the second contact portion 72 in the width direction DW is narrower than the width of the first contact portion 71 in the width direction DW, the second contact portion 72 is located between the first contacts 47b of the adjacent contact portions 47. Can pass without touching.

また、外部シェル６０の両側面板６１，６１は、それぞれ側面部５１と段差面５２との間の溝部５０ｃに挿入される。また、外部シェル６０の第１接続部６５，６５が外部ハウジング５０の下面部５４に形成された孔に挿入されて外部ハウジング５０の下面から下方へ突出する。   Further, both side plates 61, 61 of the outer shell 60 are inserted into the groove portions 50c between the side surface portion 51 and the step surface 52, respectively. Further, the first connection portions 65, 65 of the outer shell 60 are inserted into holes formed in the lower surface portion 54 of the outer housing 50 and protrude downward from the lower surface of the outer housing 50.

２つの内部シェル４０，４０のうちの一方の内部シェル４０の幅方向ＤＷの一方の側の接触部４７と他方の内部シェル４０の幅方向ＤＷの他方の側の接触部４７とが、外部シェル６０に一体に形成された接続体７０を挟持するので、２つの内部シェル４０と外部シェル６０とが接続体７０を介して導通する。   The contact portion 47 on one side of the width direction DW of the inner shell 40 of one of the two inner shells 40 and the contact portion 47 on the other side of the width direction DW of the other inner shell 40 are the outer shell. Since the connecting body 70 formed integrally with the motor 60 is sandwiched, the two inner shells 40 and the outer shell 60 are conducted through the connecting body 70.

また、２つの内部シェル４０，４０のうちの一方の内部シェル４０の幅方向ＤＷの他方の側の接触部４７（接続体７０を挟持する側の接触部とは反対側の接触部）と他方の内部シェル４０の幅方向ＤＷの一方の側の接触部４７（接続体７０を挟持する側の接触部とは反対側の接触部）とが、外部シェル６０に接触するので、２つの内部シェル４０と外部シェル６０とが導通する。   Further, the contact portion 47 on the other side in the width direction DW of one of the two inner shells 40, 40 (the contact portion on the opposite side to the contact portion on the side sandwiching the connection body 70) and the other Since the contact portion 47 on one side of the inner shell 40 in the width direction DW (the contact portion on the side opposite to the contact portion sandwiching the connection body 70) is in contact with the outer shell 60, the two inner shells 40 and the external shell 60 are electrically connected.

コネクタ１０をプリント基板に実装するには、コンタクト２０の接続部２０ｂ、内部シェル４０の接続部４８、外部シェル６０の第１、第２接続部６５，６７を、それぞれプリント基板の所定のスルーホールに挿入し、リフロー半田付け等によって半田付けすればよい。内部シェル４０の接続部４８、外部シェル６０の第１、第２接続部６５，６７がそれぞれ挿入されるスルーホールはグランドに接続されている。   In order to mount the connector 10 on the printed circuit board, the connection portion 20b of the contact 20, the connection portion 48 of the inner shell 40, and the first and second connection portions 65 and 67 of the outer shell 60 are respectively set to predetermined through holes on the printed circuit board. And soldering by reflow soldering or the like. The through holes into which the connection portion 48 of the inner shell 40 and the first and second connection portions 65 and 67 of the outer shell 60 are inserted are connected to the ground.

この実施形態によれば、上述のように内部シェル４０に覆われた内部ハウジング３０が外部ハウジング５０に収容され、その外部ハウジング５０を外部シェル６０が覆っているので、コネクタ１０を構成する部品をそれぞれ個別にプリント基板に実装する必要がなくなり、コネクタ１０を構成する部品を一体的に組み付けた状態でプリント基板に実装することができる。したがって、接続体７０と内部シェル４０との接触安定性が良く、高いシールド性が得られる。また、外部シェル６０の背面板６４を、側面板６１から延ばして形成された第１背面部６４ａと、上面板６３から延ばして形成された第２背面部６４ｂとで構成したので、複雑な金型設備を用いなくとも、高いシールド性を持つ外部シェル６０を製造することができる。   According to this embodiment, as described above, the inner housing 30 covered with the inner shell 40 is accommodated in the outer housing 50, and the outer shell 60 covers the outer housing 50. There is no need to mount each separately on the printed circuit board, and the components constituting the connector 10 can be mounted on the printed circuit board in an assembled state. Therefore, the contact stability between the connection body 70 and the inner shell 40 is good, and a high shielding property is obtained. Further, since the back plate 64 of the outer shell 60 is composed of the first back surface portion 64a formed extending from the side surface plate 61 and the second back surface portion 64b formed extending from the top surface plate 63, a complicated gold plate is formed. The outer shell 60 having a high shielding property can be manufactured without using a mold facility.

また、上述のように各内部シェル４０の接触部４７，４７は直接又は接続体７０を介して間接に外部シェル６０に電気的に接続されるので、接地箇所が多く、高いシールド性が得られる。したがって、実施形態のコネクタ１０は高速伝送用シールドコネクタとして好適である。   Moreover, since the contact parts 47 and 47 of each internal shell 40 are electrically connected to the external shell 60 directly or indirectly through the connection body 70 as described above, there are many grounding points and high shielding properties can be obtained. . Therefore, the connector 10 of the embodiment is suitable as a shield connector for high speed transmission.

更に、内部シェル４０の接続部４８及び外部シェル６０の第１、第２接続部６５，６７が、それぞれプリント基板のグランドに電気的に接続されるので、接地箇所が多くなり、シールド性が高くなる。   Further, since the connecting portion 48 of the inner shell 40 and the first and second connecting portions 65 and 67 of the outer shell 60 are electrically connected to the ground of the printed circuit board, respectively, the number of grounding points is increased and the shielding property is high. Become.

また、接続体７０が第１接触部７１と第２接触部７２とを有し、多点で内部シェル４０の接触部４７と接触するので、シールド性が高くなる。更に、２つの内部シェル４０間で電位差が殆ど無く、電位差によって生じる内部シェル４０のアンテナ作用によるノイズの発生を抑制することができる。   Moreover, since the connection body 70 has the 1st contact part 71 and the 2nd contact part 72, and contacts with the contact part 47 of the inner shell 40 in many points, shielding property becomes high. Further, there is almost no potential difference between the two inner shells 40, and the generation of noise due to the antenna action of the inner shell 40 caused by the potential difference can be suppressed.

更に、接続体７０の第２接触部７２の幅方向ＤＷの幅が第１接触部７１の幅方向ＤＷの幅よりも狭く、接続体７０を隣接する２つの接触部４７間にスムースに挿入することができるので、コネクタ１０を容易に組み立てることができる。   Furthermore, the width in the width direction DW of the second contact portion 72 of the connection body 70 is narrower than the width in the width direction DW of the first contact portion 71, and the connection body 70 is smoothly inserted between two adjacent contact portions 47. Therefore, the connector 10 can be easily assembled.

なお、上述の実施形態では、外部シェル６０の背面板６４を、側面板６１から延ばして形成された第１背面部６４ａと、上面板６３から延ばして形成された第２背面部６４ｂとで構成したが、図示しない別の実施形態として、外部シェルの背面板を、一方の側面板から延ばして形成された第１背面部と、上面板から延ばして形成された第２背面部と、他方の側面板から延ばして形成された第３背面部とで構成してもよい。外部シェルの背面板をこのように構成しても、外部シェルの製造コストを高くせずに、高いシールド性を持つ外部シェルを製造することができる。   In the above-described embodiment, the back plate 64 of the external shell 60 is configured by the first back surface portion 64 a formed by extending from the side surface plate 61 and the second back surface portion 64 b formed by extending from the top surface plate 63. However, as another embodiment (not shown), the back plate of the outer shell is formed by extending from one side plate, the second back portion formed by extending from the top plate, and the other You may comprise with the 3rd back surface part extended and formed from the side plate. Even if the back plate of the outer shell is configured in this way, an outer shell having high shielding properties can be manufactured without increasing the manufacturing cost of the outer shell.

また、上述の実施形態では、外部シェル６０の製造方法において、第１背面部６４ａ、一方の側面板６１、他方の側面板６１、第２背面部６４ｂを、一方の側面板６１、上面板６３、上面板６３、上面板６３に対して、それぞれほぼ８５度に折り曲げたが、折曲げ角度はほぼ８５度に限定されない。すなわち、折曲げ角度は金属板の厚さ、材料等によって変わり、またスプリングバック量の多少によっても変わるので、折曲げ角度は８５度から数度増減することになる。   In the above-described embodiment, in the method of manufacturing the outer shell 60, the first back surface portion 64a, the one side surface plate 61, the other side surface plate 61, and the second back surface portion 64b are replaced with the one side surface plate 61 and the top surface plate 63. The upper surface plate 63 and the upper surface plate 63 are bent at approximately 85 degrees, but the bending angle is not limited to approximately 85 degrees. That is, the bending angle varies depending on the thickness of the metal plate, the material, and the like, and also varies depending on the amount of springback, so that the bending angle is increased or decreased from 85 degrees to several degrees.

なお、上述の実施形態では、第１背面部６４ａに第１接触部７１を形成し、第２背面部６４ｂに第２接触部７２を形成したが、これと反対に、第１背面部６４ａに第２接触部７２を形成し、第２背面部６４ｂに第１接触部７１を形成してもよい。更に、別の実施態様として、第１背面部６４ａに第１接触部７１と第２接触部７２とを形成し、第２背面部６４ｂにはそれらの接触部７１，７２のいずれも形成しないようにしてもよいし、これと反対に、第２背面部６４ｂに第１接触部７１と第２接触部７２とを形成し、第１背面部６４ａにはそれらの接触部７１，７２のいずれも形成しないようにしてもよい。   In the above-described embodiment, the first contact portion 71 is formed on the first back surface portion 64a, and the second contact portion 72 is formed on the second back surface portion 64b. The 2nd contact part 72 may be formed and the 1st contact part 71 may be formed in the 2nd back surface part 64b. As another embodiment, the first contact portion 71 and the second contact portion 72 are formed on the first back surface portion 64a, and neither of the contact portions 71 and 72 is formed on the second back surface portion 64b. Alternatively, on the contrary, the first contact portion 71 and the second contact portion 72 are formed on the second back surface portion 64b, and both of the contact portions 71 and 72 are formed on the first back surface portion 64a. It may not be formed.
