Description

コネクタ用端子及び基板コネクタConnector terminal and board connector
　本発明は、基板コネクタに用いられるコネクタ用端子及び基板コネクタに関する。 The present invention relates to a connector terminal and a board connector used for a board connector.
　基板コネクタは、回路基板に固定されるハウジングと、ハウジングに取り付けられるコネクタ用端子とを備えている。コネクタ用端子は、相手方コネクタと電気的に接続される嵌合部と、回路基板と電気的に接続される基板接続部と、嵌合部と基板接続部との間を連結する連結部とを有している。連結部は、通常、直角に折り曲げられた１箇所の折り曲げ部を有している。例えば、特許文献１には、ハウジングから外部へ引き出された水平部と、水平部の後端から屈曲して下方へ略垂直に延びる垂直部とを有するコネクタ用端子が記載されている。 The board connector includes a housing fixed to the circuit board and a connector terminal attached to the housing. The connector terminal includes a fitting portion that is electrically connected to the mating connector, a board connecting portion that is electrically connected to the circuit board, and a connecting portion that connects the fitting portion and the board connecting portion. Have. The connecting portion usually has one bent portion that is bent at a right angle. For example, Patent Document 1 describes a connector terminal having a horizontal portion drawn out from a housing and a vertical portion that is bent from the rear end of the horizontal portion and extends substantially vertically downward.
　例えば自動車等の種々の分野において、コネクタの軽量化、コストダウン等が要求されている。これらの要求に対応するため、従来用いられている銅や銅合金製の端子に替えて、より比重が小さく安価なアルミニウムやアルミニウム合金製の端子（以下、「アルミニウム端子」ということがある。）を用いることが検討されている。 For example, in various fields such as automobiles, connector weight reduction and cost reduction are required. In order to meet these demands, instead of the conventionally used copper or copper alloy terminals, aluminum and aluminum alloy terminals (hereinafter sometimes referred to as “aluminum terminals”) having a lower specific gravity and lower cost. The use of is being considered.
　また、近年では、コネクタの軽量化、コストダウンに加えて、コネクタをより小型化することが望まれている。コネクタの小型化のためには、ハウジングに保持された端子のピッチを従来よりも狭くする必要がある。 In recent years, it has been desired to reduce the size of the connector in addition to reducing the weight and cost of the connector. In order to reduce the size of the connector, it is necessary to make the pitch of the terminals held in the housing narrower than before.
　アルミニウム材は、銅や銅合金に比べて縦弾性係数が小さいため、銅や銅合金に比べて、曲げ加工を施した後のスプリングバック量が大きくなることがある。アルミニウム端子に直角形状をなす折り曲げ部を形成するためには、スプリングバックを考慮して、従来よりも曲げ加工の際の曲げ角度を大きくすればよい。 Aluminum material has a smaller modulus of longitudinal elasticity than copper or copper alloy, so the amount of springback after bending may be larger than that of copper or copper alloy. In order to form a bent portion having a right-angle shape on the aluminum terminal, the bending angle at the time of bending may be made larger than the conventional one in consideration of the spring back.
特開２００７－５３００８号公報JP 2007-53008 A
　しかし、連結部に折り曲げ部を形成するための９０°曲げ加工は、コネクタのハウジングに端子が保持された状態で行われる。そのため、端子のピッチが狭くなると、９０°曲げ加工中に基板接続部などが他の端子と干渉しやすくなる。９０°曲げ加工の際に端子が他の端子と干渉すると、曲げ角度を所望の角度まで大きくすることができないため、曲げ加工が完了した後に折り曲げ部が直角にならない。 However, the 90 ° bending process for forming the bent portion in the connecting portion is performed in a state where the terminal is held in the housing of the connector. For this reason, when the pitch of the terminals is narrowed, the substrate connection portion and the like easily interfere with other terminals during the 90 ° bending process. If the terminal interferes with other terminals during the 90 ° bending process, the bending angle cannot be increased to a desired angle, so that the bent part does not become a right angle after the bending process is completed.
　このように、アルミニウム端子を端子のピッチが狭いコネクタに適用しようとすると、直角形状をなす折り曲げ部を形成することが難しいという問題がある。 Thus, when an aluminum terminal is applied to a connector having a narrow terminal pitch, there is a problem that it is difficult to form a bent portion having a right-angle shape.
　本発明は、かかる背景に鑑みてなされたものであり、曲げ加工時に基板接続部が他の端子と干渉することを回避できるコネクタ用端子及び該コネクタ用端子を有する基板コネクタを提供しようとするものである。 The present invention has been made in view of such a background, and intends to provide a connector terminal and a substrate connector having the connector terminal that can prevent the substrate connecting portion from interfering with other terminals during bending. It is.
　本発明の一態様は、基板コネクタに用いられるコネクタ用端子であって、
　アルミニウム材より構成されており、
　相手方コネクタの端子と電気的に接続される嵌合部と、
　該嵌合部と直交する方向に延びており、回路基板と電気的に接続される基板接続部と、
　上記嵌合部と上記基板接続部とを連結する連結部とを有し、

Consists of aluminum material,
A fitting portion electrically connected to the terminal of the mating connector;
A board connecting portion extending in a direction orthogonal to the fitting portion and electrically connected to the circuit board;
It has a connecting part that connects the fitting part and the board connecting part,
The connecting portion is
A plurality of bent portions;
An inclined portion interposed between the adjacent bent portions;
A connector-side end extending from the bent portion on the fitting portion side and continuing to the fitting portion;
The connector terminal has a board-side end extending from the bent part on the board connecting part side and continuing to the board connecting part.
　本発明の他の態様は、上記の態様のコネクタ用端子と、
　該コネクタ用端子を保持するハウジングとを有している、基板コネクタにある。 Another aspect of the present invention is the connector terminal of the above aspect,
A board connector having a housing for holding the connector terminal.
　上記コネクタ用端子は、上記嵌合部と上記基板接続部との間に、上記特定の形状を呈する上記連結部を有している。上記連結部は、複数回の曲げ加工を行うことにより形成された、複数の上記折り曲げ部を有している。 The connector terminal has the connecting portion exhibiting the specific shape between the fitting portion and the board connecting portion. The connecting portion has a plurality of bent portions formed by performing a plurality of bending processes.
　上記コネクタ用端子は、上記連結部の曲げ加工を複数段階に分けて行うことにより、９０°曲げ加工により１箇所の折り曲げ部を形成する場合に比べて各段階での曲げ角度を小さくすることができる。また、各段階での曲げ角度を小さくすることにより、スプリングバック量を小さくすることができる。それ故、上記コネクタ用端子は、各段階の曲げ加工中に上記基板接続部が他の端子と干渉することを回避することができる。 The connector terminal can reduce the bending angle at each stage as compared with the case where one bent part is formed by 90 ° bending by performing the bending of the connecting part in a plurality of stages. it can. Moreover, the amount of springback can be reduced by reducing the bending angle at each stage. Therefore, the connector terminal can avoid the substrate connecting portion from interfering with other terminals during the bending process in each stage.
　また、上記コネクタ用端子は、上記ハウジングに取り付けられた後に上述した曲げ加工を行うことにより、上記特定の形状に形成することができる。それ故、銅等からなる従来のコネクタ用端子に替えて、成形性の悪いアルミニウム材よりなる上記コネクタ用端子を上記ハウジングに取り付け、上記基板コネクタを構成することができる。 Also, the connector terminal can be formed into the specific shape by performing the bending process described above after being attached to the housing. Therefore, in place of a conventional connector terminal made of copper or the like, the connector terminal made of an aluminum material having poor formability can be attached to the housing to constitute the board connector.

　上記コネクタ用端子は、例えば、ピン端子やタブ端子などの種々の形態に構成することができる。これらの端子の基板接続部は、例えば、はんだ付により回路基板のスルーホール内に形成された導電部と電気的な接続を形成するように構成することができる。また、コネクタ用端子は、基板接続部を回路基板のスルーホール内に圧入することにより、スルーホール内に形成された導電部との電気的な接続を形成するプレスフィット端子として構成することもできる。 The connector terminal can be configured in various forms such as a pin terminal and a tab terminal. The board connection portions of these terminals can be configured to form an electrical connection with, for example, a conductive portion formed in the through hole of the circuit board by soldering. Further, the connector terminal can be configured as a press-fit terminal that forms an electrical connection with the conductive portion formed in the through hole by press-fitting the board connecting portion into the through hole of the circuit board. .
　また、コネクタ用端子の嵌合部は、例えばピン状やタブ状等の種々の形態を採り得る。 Also, the fitting portion of the connector terminal can take various forms such as a pin shape and a tab shape.
　コネクタ用端子を構成するアルミニウム材としては、板材あるいは線材を用いることができる。アルミニウム材の材質は、要求される機械特性や導電性、耐食性、成形性等に応じて、公知のアルミニウム及びアルミニウム合金から適宜選択することができる。強度や成形性の観点からは、コネクタ用端子が５０００系アルミニウム合金から構成されていることが好ましい。 As the aluminum material constituting the connector terminal, a plate material or a wire material can be used. The material of the aluminum material can be appropriately selected from known aluminum and aluminum alloys according to required mechanical properties, conductivity, corrosion resistance, formability, and the like. From the viewpoint of strength and formability, the connector terminal is preferably made of a 5000 series aluminum alloy.
　連結部に形成される折り曲げ部の数は、２箇所以上であればよい。しかし、折り曲げ部の数が過度に多くなると、曲げ加工における工程数が多くなり、かえって製造コストの増大を招くおそれがある。従って、製造コストの増大を回避する観点から、連結部は、２箇所の折り曲げ部を有していることが好ましい。 The number of bent parts formed in the connecting part may be two or more. However, when the number of the bent portions is excessively large, the number of steps in the bending process increases, which may increase the manufacturing cost. Therefore, from the viewpoint of avoiding an increase in manufacturing cost, the connecting part preferably has two bent parts.
　連結部が２箇所の折り曲げ部を有している場合には、端子側面視において、上記コネクタ側端部の外側表面と上記傾斜部の外側表面の延長線とのなす角度θ１と、上記基板側端部の外側表面と上記傾斜部の外側表面の延長線とのなす角度θ２とは、下記式（１）～（２）の関係を満たすことが好ましい。
　　　３０°≦θ１≦６０°　　　　・・・（１）
　　　θ２＝９０°－θ１　　　　　　・・・（２） When the connecting portion has two bent portions, the angle θ1 formed between the outer surface of the connector-side end portion and the extension line of the outer surface of the inclined portion in the side view of the terminal, and the board side The angle θ2 formed by the outer surface of the end portion and the extended line of the outer surface of the inclined portion preferably satisfies the relationship of the following formulas (1) to (2).
30 ° ≦ θ1 ≦ 60 ° (1)
θ2 = 90 ° −θ1 (2)
　この場合には、各折り曲げ部を形成するための曲げ加工において、加工中の曲げ角度を適度な大きさにすることができる。その結果、基板接続部が曲げ加工中に他の端子と干渉することを確実に回避することができる。 In this case, the bending angle during processing can be set to an appropriate size in the bending processing for forming each bent portion. As a result, it is possible to reliably avoid the substrate connecting portion from interfering with other terminals during the bending process.
　角度θ１が６０°を超える場合には、コネクタ側端部と傾斜部との間を折り曲げた後のスプリングバック量が過度に大きくなり、所望の角度まで曲げることが難しくなるおそれがある。また、角度θ１が３０°未満の場合には、角度θ２が６０°を超える。そのため、傾斜部と基板側端部との間を折り曲げた後のスプリングバック量が過度に大きくなり、所望の角度まで曲げることが難しくなるおそれがある。 When the angle θ1 exceeds 60 °, the amount of springback after bending between the connector side end and the inclined portion becomes excessively large, and it may be difficult to bend to a desired angle. Further, when the angle θ1 is less than 30 °, the angle θ2 exceeds 60 °. Therefore, the amount of spring back after bending between the inclined portion and the substrate side end portion becomes excessively large, and it may be difficult to bend to a desired angle.
　端子側面視において、上記各折り曲げ部の内側の曲率半径は０．８ｍｍ以下であることが好ましい。この場合には、各折り曲げ部を形成する際に、曲げ角度を適度な大きさにすることができる。その結果、基板接続部が曲げ加工中に他の端子と干渉することを確実に回避することができる。 When viewed from the side of the terminal, the radius of curvature inside each of the bent portions is preferably 0.8 mm or less.

Examples of the connector terminal will be described with reference to the drawings. The connector terminal 1 of this example is made of an aluminum material. As shown in FIGS. 1 and 2, the connector terminal 1 extends in a direction perpendicular to the fitting portion 2, a fitting portion 2 that is electrically connected to a terminal of a counterpart connector (not shown), It has the board | substrate connection part 4 electrically connected with the circuit board 6, and the connection part 3 which connects the fitting part 2 and the board | substrate connection part 4. FIG.
　連結部３は、２箇所の折り曲げ部３１、３２と、隣り合う折り曲げ部３１、３２の間に介在する傾斜部３４と、嵌合部２側の折り曲げ部３１から延設され、嵌合部２に連なるコネクタ側端部３３と、基板接続部４側の折り曲げ部３２から延設され、基板接続部４に連なる基板側端部３５とを有している。 The connecting portion 3 extends from the two bent portions 31, 32, the inclined portion 34 interposed between the adjacent bent portions 31, 32, and the bent portion 31 on the fitting portion 2 side. And a board-side end portion 35 extending from the bent portion 32 on the board connecting portion 4 side and continuing to the board connecting portion 4.
　本例のコネクタ用端子１は、アルミニウム合金板を打ち抜いてなるピン端子である。また、コネクタ用端子１は、ハウジング５とともに基板コネクタ１０を構成している。なお、コネクタ用端子１は、角線材から作製することもできる。 The connector terminal 1 in this example is a pin terminal formed by punching an aluminum alloy plate. The connector terminal 1 constitutes a board connector 10 together with the housing 5. The connector terminal 1 can also be made from a square wire.
　基板コネクタ１０は、複数のコネクタ用端子１と、コネクタ用端子１を保持するハウジング５とを有している。ハウジング５は合成樹脂製であり、フード部５１と、フード部５１と一体に形成された背面壁５２とを有している。フード部５１の正面は、相手方コネクタ（不図示）を収容することができるように開口している。フード部５１の内側には、嵌合部２が配置されている。 The board connector 10 includes a plurality of connector terminals 1 and a housing 5 that holds the connector terminals 1. The housing 5 is made of a synthetic resin, and includes a hood portion 51 and a back wall 52 formed integrally with the hood portion 51. The front surface of the hood part 51 is opened so that a mating connector (not shown) can be accommodated. The fitting part 2 is arranged inside the hood part 51.
　背面壁５２には、コネクタ用端子１を保持するための複数の端子圧入孔５２１が形成されている。図２に示すように、端子圧入孔５２１にはコネクタ用端子１のコネクタ側端部３３が圧入されている。これにより、コネクタ用端子１が、ハウジング５に保持されている。 A plurality of terminal press-fitting holes 521 for holding the connector terminals 1 are formed in the back wall 52. As shown in FIG. 2, the connector side end 33 of the connector terminal 1 is press-fitted into the terminal press-fitting hole 521. As a result, the connector terminal 1 is held by the housing 5.
　コネクタ側端部３３は、背面壁５２の厚み方向の外方に延出している。コネクタ側端部３３の前端には、折り曲げ部３１を介して傾斜部３４が連なっている。また、傾斜部３４の前端には、折り曲げ部３２を介して基板側端部３５が連なっている。 The connector side end 33 extends outward in the thickness direction of the back wall 52. An inclined portion 34 is connected to the front end of the connector side end portion 33 via a bent portion 31. In addition, a substrate side end portion 35 is connected to the front end of the inclined portion 34 via the bent portion 32.
　図２及び図３に示す端子側面視において、コネクタ側端部３３の外側表面３３１と傾斜部３４の外側表面３４１の延長線Ｌとのなす角度θ１と、基板側端部３５の外側表面３５１と傾斜部３４の外側表面３４１の延長線Ｌとのなす角度θ２との和は９０°である。基板接続部４が曲げ加工中に他の端子と干渉することを確実に回避する観点からは、角度θ１は３０～６０°であり、角度θ２は９０°－θ１であることが好ましい。 2 and 3, the angle θ <b> 1 formed between the outer surface 331 of the connector-side end portion 33 and the extension line L of the outer surface 341 of the inclined portion 34, and the outer surface 351 of the board-side end portion 35. The sum of the angle θ2 and the extension line L of the outer surface 341 of the inclined portion 34 is 90 °. From the viewpoint of surely avoiding the substrate connection portion 4 from interfering with other terminals during bending, the angle θ1 is preferably 30 to 60 °, and the angle θ2 is preferably 90 ° −θ1.
　本例の基板接続部４は、図２に示すように、回路基板６に形成されたスルーホール６１内に挿入され、はんだ付により回路基板６の導電部６２と電気的な接続を形成できるように構成されている。 As shown in FIG. 2, the board connecting portion 4 of this example is inserted into a through hole 61 formed in the circuit board 6, and can be electrically connected to the conductive portion 62 of the circuit board 6 by soldering. It is configured.
　次に、コネクタ用端子１の作用効果について説明する。コネクタ用端子１は、嵌合部２と基板接続部４との間に、上記特定の形状を有する連結部３を有している。連結部３は、コネクタ側端部３３と傾斜部３４との間を折り曲げる第１の曲げ加工と、傾斜部３４と基板側端部３５との間を折り曲げる第２の曲げ加工とを行うことにより形成された、２箇所の折り曲げ部３１、３２を有している。 Next, the effect of the connector terminal 1 will be described. The connector terminal 1 includes a connecting portion 3 having the specific shape between the fitting portion 2 and the board connecting portion 4. The connecting portion 3 performs a first bending process for bending between the connector-side end portion 33 and the inclined portion 34 and a second bending process for bending between the inclined portion 34 and the board-side end portion 35. The two bent portions 31 and 32 are formed.
　コネクタ用端子１は、連結部３の曲げ加工を上述したように２段階に分けて行うことにより、従来のように９０°曲げ加工により１箇所の折り曲げ部を形成する場合に比べて各段階での曲げ角度を小さくすることができる。また、各段階での曲げ角度を小さくすることにより、スプリングバック量を小さくすることができる。それ故、コネクタ用端子１は、各段階の曲げ加工中に、基板接続部４が他の端子と干渉することを回避することができる。 The connector terminal 1 performs the bending process of the connecting portion 3 in two stages as described above, so that it can be bent at each stage as compared with the conventional case where one bent part is formed by 90 ° bending. The bending angle can be reduced. Moreover, the amount of springback can be reduced by reducing the bending angle at each stage. Therefore, the connector terminal 1 can avoid the substrate connecting portion 4 from interfering with other terminals during each stage of bending.
　また、コネクタ用端子１は、ハウジング５に取り付けられた後に上述した２段階の曲げ加工を行うことにより、上記特定の形状に形成することができる。それ故、銅等からなる従来のコネクタ用端子に替えて、成形性の悪いアルミニウム材よりなるコネクタ用端子１をハウジング５に取り付け、基板コネクタ１０を構成することができる。 Further, the connector terminal 1 can be formed into the specific shape by performing the above-described two-stage bending after being attached to the housing 5. Therefore, instead of a conventional connector terminal made of copper or the like, the connector terminal 1 made of an aluminum material having poor formability can be attached to the housing 5 to constitute the board connector 10.
（実施例２）
　本例は、コネクタ用端子１に用いられるアルミニウム材の厚みや折り曲げ部３１、３２の曲げ角度を変更した場合のスプリングバック量を、モデル式を用いて推定した例である。 (Example 2)
In this example, the amount of spring back when the thickness of the aluminum material used for the connector terminal 1 and the bending angles of the bent portions 31 and 32 are changed is estimated using a model formula.
　本例においては、コネクタ用端子１に曲げ加工を行った際のスプリングバック量を下記のモデル式（３）～（４）に基づいて推定した。具体的には、種々の曲げ角度θに対して、下記モデル式における曲率半径Ｒまたは板厚ｈを変化させたときのスプリングバック量Δθを算出した。曲げ角度θは、９０°、６０°及び４５°の３水準とした。以下のモデル式（３）～（４）を用いて、折り曲げ部のスプリングバック量Δθ［°］を推定した。 In this example, the amount of spring back when the connector terminal 1 was bent was estimated based on the following model equations (3) to (4). Specifically, the springback amount Δθ when the radius of curvature R or the plate thickness h in the following model formula is changed with respect to various bending angles θ was calculated. The bending angle θ was set at three levels of 90 °, 60 ° and 45 °. Using the following model equations (3) to (4), the springback amount Δθ [°] of the bent portion was estimated.

　但し、上記式（３）におけるθ［°］は、曲げ加工が完了し、スプリングバックした後の曲げ角度である。また、上記式（４）におけるｎはアルミニウム材の加工硬化係数、Ｆはアルミニウム材の塑性係数、Ｅ［ＭＰａ］はアルミニウム材の縦弾性係数、Ｒ［ｍｍ］は端子側面視における折り曲げ部３１、３２の内側の曲率半径（図３参照）、ｈ［ｍｍ］はコネクタ用端子１の板厚である。 However, θ [°] in the above formula (3) is a bending angle after the bending process is completed and the spring back is performed. In the above formula (4), n is the work hardening coefficient of the aluminum material, F is the plastic coefficient of the aluminum material, E [MPa] is the longitudinal elastic modulus of the aluminum material, and R [mm] is the bent portion 31 in the terminal side view, The curvature radius inside 32 (see FIG. 3) and h [mm] are the plate thickness of the connector terminal 1.
　加工硬化係数ｎ、塑性係数Ｆ及び縦弾性係数Ｅの値としては、５０００系Ａｌ（アルミニウム）合金材の値を使用した。また、アルミニウム材との比較のため、従来のコネクタ用端子に多用されている黄銅材（ＪＩＳ　Ｃ２６００材）に９０°曲げ加工、即ち曲げ角度θが９０°となるように曲げ加工を施したときのスプリングバック量についても、上記と同様に算出した。 As the values of work hardening coefficient n, plasticity coefficient F and longitudinal elastic modulus E, values of 5000 series Al (aluminum) alloy material were used. Also, for comparison with aluminum material, when brass material (JIS C2600 material) frequently used for conventional connector terminals is bent at 90 °, that is, when bending angle θ is 90 °, The amount of spring back was also calculated in the same manner as described above.
　加工硬化係数ｎ、塑性係数Ｆ及び縦弾性係数Ｅの具体的な値を下表に示す。 Specific values of work hardening coefficient n, plasticity coefficient F and longitudinal elastic modulus E are shown in the table below.

　図４に、板厚ｈを０．６４ｍｍに固定し、曲率半径Ｒを変数としてスプリングバック量Δθを算出したΔθ－Ｒ曲線を示す。図４の縦軸はスプリングバック量Δθであり、横軸は曲率半径Ｒである。また、図５に、曲率半径Ｒを０．３ｍｍに固定し、板厚ｈを変数としてスプリングバック量Δθを算出した算出したΔθ－ｈ曲線を示す。図５の縦軸はスプリングバック量Δθであり、横軸は板厚ｈである。 FIG. 4 shows a Δθ-R curve in which the springback amount Δθ is calculated with the plate thickness h fixed at 0.64 mm and the radius of curvature R as a variable. The vertical axis in FIG. 4 is the springback amount Δθ, and the horizontal axis is the curvature radius R. FIG. 5 shows a calculated Δθ-h curve in which the radius of curvature R is fixed at 0.3 mm and the springback amount Δθ is calculated with the plate thickness h as a variable. The vertical axis in FIG. 5 is the springback amount Δθ, and the horizontal axis is the plate thickness h.
　図４及び図５に示したように、スプリングバック後の曲げ角度θが６０°となるように曲げ加工を行う場合の５０００系Ａｌ合金材のスプリングバック量Δθは、ＪＩＳ　Ｃ２６００材に９０°曲げ加工を行う場合と同等になると推定された。また、図４及び図５から、曲げ角度θが小さい程スプリングバック量Δθが小さくなることが理解できる。 As shown in FIGS. 4 and 5, the spring back amount Δθ of the 5000 series Al alloy material when bending is performed so that the bending angle θ after spring back is 60 ° is 90 ° bent to JIS C2600 material. It was estimated to be equivalent to the case of processing. 4 and 5 that the spring back amount Δθ decreases as the bending angle θ decreases.
　これらの結果から、コネクタ側端部３３の外側表面３３１と傾斜部３４の外側表面３４１の延長線Ｌとのなす角度θ１を３０～６０°とすることにより、折り曲げ部３１を形成した後のスプリングバック量Δθを、銅等からなる従来のコネクタ用端子と同等以下に低減できることがわかる。また、基板側端部３５の外側表面３５１と傾斜部３４の外側表面３４１の延長線Ｌとのなす角度θ２を３０～６０°にした場合にも、上記と同様に、折り曲げ部３２を形成した後のスプリングバック量Δθを、従来のコネクタ用端子と同等以下に低減できることがわかる。 From these results, the spring after forming the bent portion 31 by setting the angle θ1 between the outer surface 331 of the connector side end portion 33 and the extension line L of the outer surface 341 of the inclined portion 34 to 30 to 60 °. It can be seen that the back amount Δθ can be reduced to be equal to or less than that of a conventional connector terminal made of copper or the like. Further, when the angle θ2 formed by the outer surface 351 of the substrate side end portion 35 and the extension line L of the outer surface 341 of the inclined portion 34 is set to 30 to 60 °, the bent portion 32 is formed in the same manner as described above. It can be seen that the later springback amount Δθ can be reduced to the same level or less as that of the conventional connector terminal.
　従って、角度θ１と角度θ２とが下記式（１）～（２）の関係を満たすように折り曲げ部３１、３２を形成することにより、各段階の曲げ加工を行った後のスプリングバック量Δθを従来のコネクタ用端子と同等以下に低減し、基板接続部４と他の端子との干渉を回避することができる。
　　　３０°≦θ１≦６０°　　　　・・・（１）
　　　θ２＝９０°－θ１　　　　　　・・・（２） Therefore, by forming the bent portions 31 and 32 so that the angle θ1 and the angle θ2 satisfy the relationship of the following formulas (1) to (2), the springback amount Δθ after the bending process at each stage is obtained. It can be reduced to the same level or lower as that of a conventional connector terminal, and interference between the board connecting portion 4 and other terminals can be avoided.
30 ° ≦ θ1 ≦ 60 ° (1)
θ2 = 90 ° −θ1 (2)
　なお、本発明は、上記の実施例１～実施例２に限定されるものではなく、本発明の趣旨を損なわない範囲で適宜構成を変更することができる。 The present invention is not limited to the first and second embodiments described above, and the configuration can be changed as appropriate without departing from the spirit of the present invention.
