Description

本発明は、雌側端子の構造に係り、特に成形性の向上を図った雌側端子の構造に関する。   The present invention relates to the structure of a female terminal, and more particularly to the structure of a female terminal that is improved in formability.

従来から、雌側端子の構造として、雄側端子の導体を挿入可能な略箱状の嵌合部内に、該雄側端子の導体との接点が形成された弾性接触片を有する構造が一般的に知られている。前記弾性接触片の接点は、上記嵌合部に挿入される雄側端子の導体に対して弾性的に圧接する。   Conventionally, as a structure of the female terminal, a structure having an elastic contact piece in which a contact point with the conductor of the male terminal is formed in a substantially box-like fitting portion into which the conductor of the male terminal can be inserted is generally used. Known to. The contact of the elastic contact piece is elastically pressed against the conductor of the male terminal inserted into the fitting portion.

図10は、上記従来における雌側端子の構造の一例を示す斜視図、図11,図12は電気接触部の断面図(図10のA−A断面図)である。   FIG. 10 is a perspective view showing an example of the structure of the female terminal in the prior art, and FIGS. 11 and 12 are cross-sectional views of the electrical contact portion (A-A cross-sectional view of FIG. 10).

図10に示すように、雌型端子1は略箱状の電気接触部2と、電線接続部3と、で形成されている。   As shown in FIG. 10, the female terminal 1 is formed of a substantially box-shaped electrical contact portion 2 and a wire connection portion 3.

図11,図12に示すように、前記電気接触部2内の底壁5側には弾性接触片10が設けられており、この弾性接触片10には、天壁6側へ突出する接点bが形成されている。また、電気接触部2内の天壁6には、弾性接触片10に対向して接点cが形成されている。   As shown in FIGS. 11 and 12, an elastic contact piece 10 is provided on the bottom wall 5 side in the electric contact portion 2, and the elastic contact piece 10 has a contact b protruding toward the top wall 6 side. Is formed. Further, a contact c is formed on the top wall 6 in the electrical contact portion 2 so as to face the elastic contact piece 10.

前記雌側端子1の電気接触部2内に雄側端子の導体14が挿入されると、前記弾性接触片10の接点bと天壁の接点cとにより雄側端子の導体14が挟持され、雌側端子1と雄側端子が電気的に接続されることとなる。   When the male terminal conductor 14 is inserted into the electrical contact portion 2 of the female terminal 1, the male terminal conductor 14 is sandwiched between the contact b of the elastic contact piece 10 and the contact c of the top wall, The female terminal 1 and the male terminal are electrically connected.

なお、箱状の電気接触部2は、図13(図11のB−B断面図),図14に示すように、弾性接触片10と内側底壁5aは連続して形成されており、内側底壁5aから内側側壁4a,天壁6,側壁4b,外側底壁5b,外側側壁4cの順に折り曲げられて弾性接触片10を包むように保護している。   In addition, as shown in FIG. 13 (BB sectional view of FIG. 11) and FIG. 14, the box-shaped electric contact portion 2 has the elastic contact piece 10 and the inner bottom wall 5a formed continuously, The bottom wall 5a is bent in the order of the inner side wall 4a, the top wall 6, the side wall 4b, the outer bottom wall 5b, and the outer side wall 4c to protect the elastic contact piece 10 so as to be wrapped.

特開2010−123264号公報JP 2010-123264 A

しかしながら、従来の雌側端子1の構造では、電気接触部2を成形する際にスプリングバックを想定した形状となっておらず、内側側壁4aと外側側壁4cとが干渉してしまい、弾性接触片10に捩れが発生してしまっていた。   However, in the structure of the conventional female terminal 1, the shape of the spring contact is not assumed when the electrical contact portion 2 is formed, and the inner side wall 4a and the outer side wall 4c interfere with each other, and the elastic contact piece 10 was twisted.

すなわち、電気接触部2は折り曲げて成形することによりスプリングバックが発生するため、予め、外側側壁4cは外側底壁5bに対して垂直な状態よりも内側側壁4a側に折曲する必要がある。   That is, since the electrical contact portion 2 is bent and molded to generate a springback, the outer side wall 4c needs to be bent in advance toward the inner side wall 4a rather than being perpendicular to the outer bottom wall 5b.

しかし、図13に示すように、内側側壁4aと外側側壁4cとの間には隙間がないため、スプリングバックを想定し、外側側壁4cを外側底壁5bに対して垂直な状態よりも内側側壁4a側へ折曲すると、外側側壁4cが内側側壁4aに接触し、図15に示すように内側側壁4aが変形してしまっていた。そのため、内側側壁4aと一体に成形された内側底壁5a,弾性接触片10に捩れが生じてしまい、端子の成型性が良くなかった。   However, as shown in FIG. 13, there is no gap between the inner side wall 4a and the outer side wall 4c. Therefore, assuming the spring back, the outer side wall 4c is located on the inner side wall more than the state perpendicular to the outer bottom wall 5b. When bent to the 4a side, the outer side wall 4c contacted the inner side wall 4a, and the inner side wall 4a was deformed as shown in FIG. Therefore, the inner bottom wall 5a formed integrally with the inner side wall 4a and the elastic contact piece 10 are twisted, and the moldability of the terminal is not good.

また、弾性接触片10に捩れが生じることにより、雄側端子の導体14と弾性接触片10との接触が不安定になってしまい、雄側端子と雌側端子1との接続が不安定になる可能性があった。このように雄側端子と雌側端子1との接続が不安定になると、通電性が悪化して信号電流の伝達が不正確になることや、導通抵抗が増加して端子が加熱してしまうような問題が生じてしまっていた。   Further, since the elastic contact piece 10 is twisted, the contact between the male terminal conductor 14 and the elastic contact piece 10 becomes unstable, and the connection between the male terminal and the female terminal 1 becomes unstable. There was a possibility. If the connection between the male terminal and the female terminal 1 becomes unstable in this way, the conductivity is deteriorated and the transmission of the signal current becomes inaccurate, or the conduction resistance increases and the terminal is heated. Such a problem has occurred.

以上示したようなことから、雌側端子成形時における内壁と外壁との接触を回避し、弾性接触片の捩れを抑制することが課題となる。   As described above, it becomes a problem to avoid the contact between the inner wall and the outer wall during molding of the female terminal and to suppress the twist of the elastic contact piece.

本発明は、前記従来の問題に鑑み、案出されたもので、その一態様は、天壁,側壁,底壁と、前記天壁,側壁,底壁のうち何れか1つと一体に形成され、雄側端子の導体との接点を有する弾性接触片と、を備えた1枚の金属板を折り曲げて雄側端子の導体が挿入可能な箱状に形成され、前記弾性接触片と一体に形成された面の隣りの面のうち少なくとも一方が内壁と外壁とで二重に構成された電気接触部を備えた雌側端子の構造であって、前記電気接触部の成形時に、前記弾性接触片と一体に形成された面の隣の面のうち、二重に構成された内壁と外壁との間に隙間が形成されたことを特徴とする。   The present invention has been devised in view of the above-described conventional problems, and one aspect thereof is formed integrally with any one of the top wall, the side wall, and the bottom wall and the top wall, the side wall, and the bottom wall. An elastic contact piece having a contact point with the conductor of the male terminal, and is formed into a box shape into which the conductor of the male terminal can be inserted by bending a single metal plate, and formed integrally with the elastic contact piece A structure of a female terminal having an electrical contact portion in which at least one of the adjacent surfaces is doubled by an inner wall and an outer wall, and when the electrical contact portion is molded, the elastic contact piece A gap is formed between the inner wall and the outer wall that are doubled among the surfaces adjacent to the surface formed integrally with the outer wall.

また、他の態様として、前記電気接触部は、内側底壁と、内側側壁と、内側天壁と、側壁と、外側底壁と、外側側壁と、外側天壁と、前記内側底壁と一体に形成された弾性接触片と、を備え、前記内側底壁を内側にして、内側側壁,内側天壁,側壁,外側底壁,外側側壁,外側天壁の順に折り曲げて形成され、前記電気接触部の成形時に、前記内側側壁と外側側壁との間に隙間を形成しても良い。   As another aspect, the electrical contact portion is integrated with the inner bottom wall, the inner side wall, the inner top wall, the side wall, the outer bottom wall, the outer side wall, the outer top wall, and the inner bottom wall. An elastic contact piece formed on the inner bottom wall, the inner side wall, the inner ceiling wall, the side wall, the outer bottom wall, the outer side wall, and the outer ceiling wall, and are formed by bending in this order. When forming the part, a gap may be formed between the inner side wall and the outer side wall.

また、他の態様として、前記外側側壁の上端部にはスタビライザが形成されており、前記内側側壁は、内側側壁の天壁側が底壁側よりも側壁側に位置するように傾けて成形しても良い。   Further, as another aspect, a stabilizer is formed at an upper end portion of the outer side wall, and the inner side wall is formed so as to be inclined so that the top wall side of the inner side wall is located on the side wall side rather than the bottom wall side. Also good.

本発明によれば、雌側端子成形時における内壁と外壁との接触を回避し、弾性接触片に捩れが発生することを抑制することが可能となる。   According to the present invention, it is possible to avoid contact between the inner wall and the outer wall at the time of female-side terminal molding, and to prevent the elastic contact piece from being twisted.

以下、実施形態1,2における雌側端子の構造を図1〜図9に基づき詳細に説明する。   Hereinafter, the structure of the female terminal in the first and second embodiments will be described in detail with reference to FIGS.

[実施形態1]
図1は、本実施形態における雌側端子の構造を示す斜視図である。図1に示すように、雌側端子1は、電気接触部2と、電線接続部3と、を備える。
[Embodiment 1]
FIG. 1 is a perspective view showing the structure of the female terminal in the present embodiment. As shown in FIG. 1, the female terminal 1 includes an electrical contact portion 2 and a wire connection portion 3.

前記電線接続部3は、図1に示すように、電気接触部2の側壁4,4と底壁5から雌側端子1後半の桶状壁7を経て続いており、圧着片8,9が形成されている。   As shown in FIG. 1, the electric wire connecting portion 3 continues from the side walls 4 and 4 and the bottom wall 5 of the electric contact portion 2 through the saddle-like wall 7 of the rear side of the female terminal 1. Is formed.

図2は、図1のC−C断面図である。図1,図2に示すように、電気接触部2は略箱状に形成されている。   2 is a cross-sectional view taken along the line CC of FIG. As shown in FIGS. 1 and 2, the electrical contact portion 2 is formed in a substantially box shape.

電気接触部2の底壁5は、内側底壁5aと外側底壁5bとで二重に構成されており、内側底壁5aには弾性接触片10が一体に形成されている。外側底壁5bには突起11が形成されており、弾性接触片10が外側底壁5b側に押圧された場合、弾性接触片10は突起11により天壁6側に弾性力を有することとなる。   The bottom wall 5 of the electrical contact portion 2 is composed of an inner bottom wall 5a and an outer bottom wall 5b, and an elastic contact piece 10 is integrally formed on the inner bottom wall 5a. A protrusion 11 is formed on the outer bottom wall 5b, and when the elastic contact piece 10 is pressed toward the outer bottom wall 5b, the elastic contact piece 10 has an elastic force on the top wall 6 side by the protrusion 11. .

弾性接触片10の先端側は略半弧状に屈曲されており、この頂点が雄側端子の導体との接点10bとなる。また、外側底壁5bには弾性接触片10の先端に対応する位置に逃げ孔5cが形成されており、弾性接触片10が外側底壁5b側に変位した際には、弾性接触片10の先端がこの逃げ孔5cに挿入することとなる。   The tip end side of the elastic contact piece 10 is bent in a substantially semi-arc shape, and this apex serves as a contact 10b with the conductor of the male terminal. Further, the outer bottom wall 5b is formed with a relief hole 5c at a position corresponding to the tip of the elastic contact piece 10. When the elastic contact piece 10 is displaced toward the outer bottom wall 5b, the elastic contact piece 10 The tip is inserted into the escape hole 5c.

電気接触部2の天壁6は、内側天壁6aと外側天壁6bとで二重に構成されており、内側天壁6aには弾性接触片10に対向する接点6c,6dが形成されている。外側天壁6bには、端子係止ランスと係止される突起6eが形成されている。   The top wall 6 of the electrical contact portion 2 is composed of an inner ceiling wall 6a and an outer ceiling wall 6b. The inner ceiling wall 6a has contacts 6c and 6d facing the elastic contact piece 10. Yes. The outer top wall 6b is formed with a protrusion 6e that is locked to the terminal locking lance.

図3に示すように、雄側端子のタブ状接触片14が、雌側端子1の電気接触部2内に挿入されると、弾性接触片10はタブ状接触片14によって底壁5側に押し付けられて変位する。この時、弾性接触片10の先端は外側底壁5bの逃げ孔5cに挿入されることとなる。   As shown in FIG. 3, when the tab-like contact piece 14 of the male terminal is inserted into the electrical contact portion 2 of the female terminal 1, the elastic contact piece 10 is moved to the bottom wall 5 side by the tab-like contact piece 14. It is displaced by being pressed. At this time, the tip of the elastic contact piece 10 is inserted into the escape hole 5c of the outer bottom wall 5b.

そして、タブ状接触片14は、天壁6に形成された接点6c,6dと、弾性接触片10の接点10bと、の3点で雌側端子1の電気接触部2と接触することとなる。また、弾性接触片10の接点10bからタブ状接触片14に対して弾性力による接触荷重が生じるため、接点10bはタブ状接触片14に弾性接触し、安定した接触が維持される。   The tab-like contact piece 14 comes into contact with the electrical contact portion 2 of the female terminal 1 at three points, that is, the contacts 6c and 6d formed on the top wall 6 and the contact 10b of the elastic contact piece 10. . Further, since a contact load due to elastic force is generated from the contact point 10b of the elastic contact piece 10 to the tab-like contact piece 14, the contact point 10b elastically contacts the tab-like contact piece 14 and a stable contact is maintained.

図4は、前記電気接触部2の展開図である。なお、図4では、電気接触部2のみを示し、電線接続部3は図示省略している。図4に示すように、前記雌側端子1は銅合金等の一枚の金属板からプレスで展開状態に打ち抜きされた後、所要の形状に折り曲げ成形される。   FIG. 4 is a development view of the electrical contact portion 2. In FIG. 4, only the electrical contact portion 2 is shown, and the wire connection portion 3 is not shown. As shown in FIG. 4, the female terminal 1 is punched out of a single metal plate such as a copper alloy in a developed state, and then bent into a required shape.

また、外側側壁4cには端子の逆挿入防止のためのスタビライザ13が形成されており、スタビライザ13には、そのスタビライザ13の強度を向上させるための打ち出し13aが形成されている。   Further, a stabilizer 13 for preventing reverse insertion of the terminal is formed on the outer side wall 4c, and a protrusion 13a for improving the strength of the stabilizer 13 is formed on the stabilizer 13.

図4に示すように、電気接触部2は、内側底壁5a,内側側壁4a,内側天壁6a,側壁4b,外側底壁5b,外側側壁4c,外側天壁6bの順に形成されている。そして、内側底壁5a(弾性接触片10)を内側にして内側側壁4a,内側天壁6a,…,外側天壁6bの順に折り曲げられて、図5に示すような箱状の電気接触部2が成形される。   As shown in FIG. 4, the electrical contact portion 2 is formed in the order of an inner bottom wall 5a, an inner side wall 4a, an inner top wall 6a, a side wall 4b, an outer bottom wall 5b, an outer side wall 4c, and an outer top wall 6b. Then, the inner side wall 4a, the inner top wall 6a,..., And the outer top wall 6b are bent in this order with the inner bottom wall 5a (elastic contact piece 10) on the inside, and a box-shaped electric contact portion 2 as shown in FIG. Is formed.

図6は、電気接触部2の断面図(図2のD−D断面図)である。図6に示すように、本実施形態1における電気接触部2は、内側側壁4aと外側側壁4cとが密着しておらず、隙間hが設けられている。すなわち、外側側壁4cは、内側側壁4aに対して隙間h離れた位置に設けられている。   FIG. 6 is a cross-sectional view (DD cross-sectional view of FIG. 2) of the electrical contact portion 2. As shown in FIG. 6, in the electrical contact portion 2 in Embodiment 1, the inner side wall 4a and the outer side wall 4c are not in close contact with each other, and a gap h is provided. That is, the outer side wall 4c is provided at a position away from the inner side wall 4a by a gap h.

図7は、外側側壁4cを成形する際の外側側壁4cの位置を表した図である。内側底壁5a(弾性接触片10)を内側にして内側側壁4a,内側天壁6a,側壁4b,外側底壁5bまで折り曲げた後、図7に示すように、外側側壁4cを正規の角度(外側底壁5bに対して垂直の角度)よりも内側側壁4a側に折曲させる。その後、前記外側側壁4cはスプリングバックにより正規の角度に戻る。すなわち、外側側壁4cは、本来成形させたい角度よりも、スプリングバックを見込んで内側側壁4a側に折曲され、その後、スプリングバックにより本来外側側壁4cを形成させたい角度に戻る。   FIG. 7 is a view showing the position of the outer side wall 4c when the outer side wall 4c is molded. After bending the inner bottom wall 5a (elastic contact piece 10) to the inner side wall 4a, the inner top wall 6a, the side wall 4b, and the outer bottom wall 5b, as shown in FIG. The inner side wall 4a is bent more than the angle (perpendicular to the outer bottom wall 5b). Thereafter, the outer side wall 4c returns to a normal angle by springback. That is, the outer side wall 4c is bent toward the inner side wall 4a in anticipation of the spring back from the angle that is originally desired to be molded, and then returns to the angle at which the outer side wall 4c is originally formed by the spring back.

本実施形態1における雌側端子1の構造は、内側側壁4aと外側側壁4cとの間に隙間hが設けられているため、端子成形時に外側側壁4cを正規の位置よりも内側側壁4a側に折曲させても外側側壁4cと内側側壁4aとが干渉することを防止し、弾性接触片10が捩れてしまうことを抑制する。   In the structure of the female terminal 1 according to the first embodiment, since the gap h is provided between the inner side wall 4a and the outer side wall 4c, the outer side wall 4c is positioned closer to the inner side wall 4a than the normal position when molding the terminal. Even if bent, the outer side wall 4c and the inner side wall 4a are prevented from interfering with each other, and the elastic contact piece 10 is prevented from being twisted.

すなわち、内側側壁4aと外側側壁4cとの間に隙間hが設けられておらず隣接している場合は、スプリングバックを見込んで外側側壁4cを正規の角度(本来、外側側壁4cを成形させたい角度)よりも内側側壁4a側に折曲すると、外側側壁4cが内側側壁4aに接触してしまい、内側側壁4aが変形してしまっていた。その結果、内側側壁4aと一体に形成された弾性接触部10に捩れが生じてしまっていた。   That is, when the gap h is not provided between the inner side wall 4a and the outer side wall 4c, the outer side wall 4c is positioned at a regular angle (originally, the outer side wall 4c is desired to be molded) in anticipation of springback. If the inner side wall 4a is bent more than the angle), the outer side wall 4c comes into contact with the inner side wall 4a, and the inner side wall 4a is deformed. As a result, the elastic contact portion 10 formed integrally with the inner side wall 4a has been twisted.

それに対し、本実施形態1における雌側端子1の構造では、内側側壁4aと外側側壁4cとの間に隙間hが設けられているため、端子成形時にスプリングバックを見込んで正規の角度(本来、外側側壁4cを成形させたい角度)よりも内側側壁4a側に折り曲げても、外側側壁4cと内側側壁4aとが接触することがなく、弾性接触片10に捩れが生じることを防止することが可能となり、端子の成型性が向上する。   On the other hand, in the structure of the female terminal 1 in the first embodiment, the gap h is provided between the inner side wall 4a and the outer side wall 4c. The outer side wall 4c and the inner side wall 4a do not come into contact with each other even when the outer side wall 4c is bent toward the inner side wall 4a than the angle at which the outer side wall 4c is desired to be formed, and the elastic contact piece 10 can be prevented from being twisted. Thus, the moldability of the terminal is improved.

また、弾性接触片10に捩れが生じることにより、雄側端子の導体(タブ状接触片)14と雌側端子1の電気接触部2との安定的な接触を維持し、通電性が悪化して信号電流の伝達が不正確になることや、導通抵抗が増加して端子が加熱する等の問題を抑制することが可能となる。   Further, when the elastic contact piece 10 is twisted, the stable contact between the conductor (tab-like contact piece) 14 of the male terminal and the electrical contact portion 2 of the female terminal 1 is maintained, and the conductivity is deteriorated. Thus, it is possible to suppress problems such as inaccurate transmission of signal current and increase of conduction resistance and heating of the terminal.

[実施形態2]
図8は、本実施形態2における雌側端子1の構造を示す断面図(図2のD−D断面図)である。なお、実施形態1と同様の構成については、同様の符号を付して、その説明を省略する。
[Embodiment 2]
FIG. 8 is a cross-sectional view (DD cross-sectional view of FIG. 2) showing the structure of the female terminal 1 in the second embodiment. In addition, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

本実施形態2における雌側端子1の構造と実施形態1における雌側端子の構造との相違点は、図8に示すように、内側側壁4aが外側側壁4cに対して角度i傾いた状態で成形されている点である。すなわち、内側側壁4aは、内側天壁6a側が内側底壁5a側よりも側壁4b側に形成されている。   The difference between the structure of the female terminal 1 in the second embodiment and the structure of the female terminal in the first embodiment is that the inner side wall 4a is inclined at an angle i with respect to the outer side wall 4c, as shown in FIG. It is a point that is molded. That is, as for the inner side wall 4a, the inner top wall 6a side is formed on the side wall 4b side rather than the inner bottom wall 5a side.

また、本実施形態2では、実施形態1よりも、スタビライザ13に形成された打ち出し13aが、スタビライザ13内の広範囲に亘って形成されている。   Further, in the second embodiment, the launch 13 a formed in the stabilizer 13 is formed over a wider area in the stabilizer 13 than in the first embodiment.

前記打ち出し13aは内側側壁4a側に突出しているため、この打ち出し13aを内側天壁6aの位置に至るまで大きく形成すると、スプリングバックを見込んで外側側壁4cを正規の位置より内側側壁4a側に折曲した場合、この打ち出し13a部分が内側側壁4aと接触し、内側底壁5aが変形し、弾性接触片10に捩れが生じることとなる。   Since the punching 13a protrudes toward the inner side wall 4a, if the punching 13a is formed to reach the position of the inner top wall 6a, the outer side wall 4c is folded from the normal position toward the inner side wall 4a in view of the spring back. In the case of bending, the projecting portion 13a comes into contact with the inner side wall 4a, the inner bottom wall 5a is deformed, and the elastic contact piece 10 is twisted.

そこで、本実施形態2のように、内側側壁4aを外側側壁4cに対して角度i傾いた状態で成形することにより、内側側壁4aの内側天壁6a側は内側底壁5a側よりも側壁4b側に位置するため、打ち出し13aを大きく形成し、スプリングバックを見込んで外側側壁4cを正規の位置より内側側壁4a側に折曲しても、内側側壁4aが外側側壁4cと接触して、弾性接触片10に捩れが生じるとを抑制することが可能となり、端子の成型性が向上する。   Therefore, as in the second embodiment, by molding the inner side wall 4a with the angle i inclined with respect to the outer side wall 4c, the inner top wall 6a side of the inner side wall 4a is more side wall 4b than the inner bottom wall 5a side. Therefore, even if the outer side wall 4c is bent to the inner side wall 4a side from the normal position in anticipation of the spring back, the inner side wall 4a comes into contact with the outer side wall 4c and is elastic. It becomes possible to suppress that the contact piece 10 is twisted, and the moldability of the terminal is improved.

また、スタビライザ13内に広範囲に亘って打ち出しkを形成することにより、スタビライザ13の強度が向上した範囲が大きくなり、その結果、スタビライザ13の強度の向上を図ることが可能となる。   Further, by forming the launch k over a wide range in the stabilizer 13, the range in which the strength of the stabilizer 13 is improved is increased, and as a result, the strength of the stabilizer 13 can be improved.

以上、本発明において、記載された具体例に対してのみ詳細に説明したが、本発明の技術思想の範囲で多彩な変形および修正が可能であることは、当業者にとって明白なことであり、このような変形および修正が特許請求の範囲に属することは当然のことである。   Although the present invention has been described in detail only for the specific examples described above, it is obvious to those skilled in the art that various changes and modifications are possible within the scope of the technical idea of the present invention. Such variations and modifications are naturally within the scope of the claims.

例えば、実施形態1,2では、内側底壁5aに弾性接触片10が一体に形成されていたが、弾性接触片10が形成されるのは内側底壁5でなくとも良い。実施形態1の場合、弾性接触片10が形成された面の隣の面に相当する内壁と、その内壁の外壁との間に隙間hを設けることとなる。また、実施形態2では、弾性接触片10が形成された面の隣の面に相当する内壁が傾斜して形成されることとなる。   For example, in the first and second embodiments, the elastic contact piece 10 is integrally formed on the inner bottom wall 5a, but the elastic contact piece 10 may not be formed on the inner bottom wall 5. In the case of the first embodiment, a gap h is provided between the inner wall corresponding to the surface adjacent to the surface on which the elastic contact piece 10 is formed and the outer wall of the inner wall. In the second embodiment, the inner wall corresponding to the surface adjacent to the surface on which the elastic contact piece 10 is formed is formed to be inclined.
