 上述のようなコンタクトを第二部材に接触させる際、コンタクトを電位差の大きい相手側金属と接触させると、異種金属の接触に起因する腐食(例えば、ガルバニック腐食等。)が発生することがある。このような腐食が発生した場合、コンタクトと第二部材との間において、抵抗値が大きく上がってしまう、という問題がある。特に、自動車のエンジンルーム内のように、高温と低温が急激に変化する環境下においては、上述のような現象が発生しやすくなる。 When the contact as described above is brought into contact with the second member, if the contact is brought into contact with a counterpart metal having a large potential difference, corrosion (for example, galvanic corrosion or the like) due to the contact of the different metal may occur. When such corrosion occurs, there is a problem that the resistance value increases greatly between the contact and the second member. In particular, the phenomenon as described above is likely to occur in an environment in which high and low temperatures change rapidly, such as in an engine room of an automobile.
 以上のような事情から、上述のような腐食が原因で抵抗値が上昇してしまうのを抑制可能なコンタクトを提供することが望ましい。 In view of the above circumstances, it is desirable to provide a contact that can suppress an increase in resistance due to the above-described corrosion.

The base portion, the contact portion, and the spring portion are integrally formed of a thin metal plate, and the spring portion is a thin plate. The contact portion has a flat plate portion extending in a flat plate shape from one end of the bent portion, and the flat plate portion includes at least one contact location. As one of the projections protruding toward the second member side Vignetting projections is provided at a position apart more than 0.9mm to contact portion side from the boundary between the contact portion and the spring portion.
 このように構成されたコンタクトによれば、基部を第一部材に対して固定して、コンタクトを第一部材と第二部材との間に挟み込むと、接触部が、少なくとも一つの接触箇所で第二部材に接触する。これにより、第一部材と第二部材を電気的に接続することができる。 According to the contact configured as described above, when the base portion is fixed to the first member and the contact is sandwiched between the first member and the second member, the contact portion becomes the first at at least one contact point. Contact two members. Thereby, the first member and the second member can be electrically connected.
 また、接触部は、上述のような突起の先端で第二部材に接触する。そのため、このような突起が設けられていない場合に比べ、小さな接触箇所でコンタクトを第二部材に接触させることができる。したがって、突起のない大きな接触面で第二部材に接触するコンタクトに比べ、接触圧を高めることができる。これにより、接触箇所に酸素や水等が入り込むのを抑制できる。このため、腐食が発生するのを抑制できる。また、いくらか腐食が発生したとしても、小さな接触箇所で発生した腐食であれば、突起と第二の部材が擦れ合うことで腐食箇所が成長する前に腐食箇所を削り落とすことができる。よって、腐食箇所が拡がるのを抑制でき、コンタクトと第二部材との間において抵抗値が上がるのを抑制することができる。 Also, the contact portion contacts the second member at the tip of the protrusion as described above. Therefore, compared with the case where such a protrusion is not provided, the contact can be brought into contact with the second member at a small contact location. Therefore, the contact pressure can be increased as compared with a contact that contacts the second member with a large contact surface without a protrusion. Thereby, it can suppress that oxygen, water, etc. enter into a contact location. For this reason, generation | occurrence | production of corrosion can be suppressed. Even if some corrosion occurs, if the corrosion occurs at a small contact location, the corrosion location can be scraped off before the corrosion location grows by rubbing the protrusion and the second member. Therefore, it can suppress that a corrosion location spreads and can suppress that resistance value goes up between a contact and a 2nd member.
 さらに、上述のような突起は、接触部とばね部との境界から接触部側へ0.9mm以上離れた位置に設けられている。接触部とばね部との境界は、上述の平板部と曲げ部との境界である。このような位置に突起が設けられていると、接触部とばね部との境界から接触部側へ0.9mm未満しか離れていない位置に同様な突起が設けられている場合に比べ、平板部が突起を支点にしてシーソーのように上下に揺動するのを抑制できる。これにより、接触部とばね部との境界付近に作用する応力が過大になるのを抑制することができ、ばね部が破損するのを抑制することができる。したがって、例えば車載機器のように、振動が伝わる環境においてコンタクトが使用されたとしても、長期にわたってばね部が破断するのを抑制でき、コンタクトを有効に機能させることができる。 Furthermore, the projections as described above are provided at a position separated by 0.9 mm or more from the boundary between the contact portion and the spring portion toward the contact portion. The boundary between the contact portion and the spring portion is the boundary between the flat plate portion and the bending portion described above. When the protrusion is provided at such a position, the flat plate portion is compared with the case where a similar protrusion is provided at a position that is less than 0.9 mm from the boundary between the contact portion and the spring portion to the contact portion side. Can be prevented from swinging up and down like a seesaw with the projection as a fulcrum. Thereby, it can suppress that the stress which acts on the boundary vicinity of a contact part and a spring part becomes excessive, and can suppress that a spring part is damaged. Therefore, even if the contact is used in an environment where vibration is transmitted, for example, in a vehicle-mounted device, the spring portion can be prevented from breaking for a long period of time, and the contact can function effectively.

 次に、上述のコンタクトについて、例示的な実施形態を挙げて説明する。なお、以下の説明においては、図中に併記した前後左右上下の各方向を利用して説明を行う。これらの各方向は、コンタクトの六面図(図2A~図2F参照。)において、正面図に表れる箇所が向けられる方向を前、背面図に表れる箇所が向けられる方向を後、左側面図に表れる箇所が向けられる方向を左、右側面図に表れる箇所が向けられる方向を右、平面図に表れる箇所が向けられる方向を上、底面図に表れる箇所が向けられる方向を下、と規定した相対的な方向である。ただし、これらの各方向は、コンタクトを構成する各部の相対的な位置関係を簡潔に説明するために規定した方向に過ぎない。したがって、例えばコンタクトの使用時等に、コンタクトをどのような方向に向けて配置するかは任意である。 Next, the contact described above will be described with reference to an exemplary embodiment. In the following explanation, explanation will be made using the front, rear, left, right and up directions shown in the figure. In these six directions of the contact (see FIGS. 2A to 2F), the direction in which the part appearing in the front view is directed forward, the direction in which the part appearing in the rear view is directed, and the left side view. Relative defining the direction in which the appearing part is directed as the left, the direction in which the part appearing in the right side view is directed to the right, the direction in which the part appearing in the plan view is directed up, and the direction in which the part appearing in the bottom view is directed down Direction. However, each of these directions is only a direction defined in order to briefly describe the relative positional relationship between the respective parts constituting the contact. Therefore, for example, when the contacts are used, the direction in which the contacts are arranged is arbitrary.
  [コンタクトの構成]
 図1A,図1B,図2A,図2B,図2C,図2D,図2E,図2F,及び図3に示すように、コンタクト1は、第一部材に取り付けられて第一部材と第二部材との間に挟み込まれることにより第一部材と第二部材とを電気的に接続可能な部品である。第一部材の例としては、例えば電子回路基板を挙げることができる。この場合、コンタクト1は、電子回路基板が備える導体パターンに対してはんだ付けされる。第二部材の例としては、電子回路基板とは別の導電性部材を挙げることができ、例えば、電子機器が備える金属製ケース、金属製パネル、金属製フレーム、及び、金属めっきが施された各種部品等を挙げることができる。
[Composition of contact]
As shown in FIGS. 1A, 1B, 2A, 2B, 2C, 2D, 2E, 2F, and 3, the contact 1 is attached to the first member to be the first member and the second member. Is a component that can be electrically connected to the first member and the second member. An example of the first member is an electronic circuit board. In this case, the contact 1 is soldered to a conductor pattern included in the electronic circuit board. As an example of the second member, a conductive member different from the electronic circuit board can be cited. For example, a metal case, a metal panel, a metal frame, and metal plating provided in the electronic device are applied. Various parts can be listed.
 コンタクト1は、基部3、接触部5、ばね部7、2つの延出部9,9、2つの立設壁11,11、及び係合片13などを備える。これら基部3、接触部5、ばね部7、2つの延出部9,9、2つの立設壁11,11、及び係合片13は、金属の薄板(本実施形態の場合は、リフロー処理が施されたすずめっき付きのばね用ベリリウム銅の薄板。)によって一体成形されている。本実施形態の場合、薄板の板厚は、0.1mm以上かつ0.15mm以下とされている(図には板厚0.12mmの場合を例示。)。また、コンタクト1は、外形寸法(図中でいう左右方向寸法×前後方向寸法×上下方向寸法。)が2mm×2mm×2mm以上かつ10mm×10mm×10mm以下の範囲内に収まる形状に構成されている(図には外形寸法が5mm×3.2mm×5.3mmの場合を例示。)。 The contact 1 includes a base portion 3, a contact portion 5, a spring portion 7, two extending portions 9, 9, two standing walls 11, 11, an engagement piece 13, and the like. These base part 3, contact part 5, spring part 7, two extending parts 9, 9, two standing walls 11, 11, and engagement piece 13 are made of a thin metal plate (in this embodiment, a reflow process). A thin plate of beryllium copper for springs with tin plating). In the case of the present embodiment, the plate thickness of the thin plate is 0.1 mm or more and 0.15 mm or less (the case where the plate thickness is 0.12 mm is illustrated in the figure). Further, the contact 1 is configured to have a shape in which the external dimensions (the horizontal dimension in the figure × the longitudinal dimension × the vertical dimension) are within a range of 2 mm × 2 mm × 2 mm or more and 10 mm × 10 mm × 10 mm or less. (The figure shows an example in which the external dimensions are 5 mm × 3.2 mm × 5.3 mm.)
 基部3は、第一部材に対して固定可能に構成されている。本実施形態の場合、第一部材としては電子回路基板が想定されている。そのため、基部3には、電子回路基板が備える導体パターンに対してはんだ付けされる接合面15が設けられ、はんだ付けによって電子回路基板に対して固定可能に構成されている。また、本実施形態の場合、基部3から2つの立設壁11,11にわたる範囲には、開口17が設けられている。そのため、基部3は、開口17を挟む両側(図中でいう左右方向両側。)に分断されている。 The base 3 is configured to be fixable to the first member. In the case of this embodiment, an electronic circuit board is assumed as the first member. Therefore, the base 3 is provided with a joint surface 15 to be soldered to a conductor pattern provided in the electronic circuit board, and is configured to be fixed to the electronic circuit board by soldering. In the case of this embodiment, an opening 17 is provided in a range extending from the base 3 to the two standing walls 11 and 11. Therefore, the base portion 3 is divided into both sides (both sides in the left-right direction in the figure) sandwiching the opening 17.
 接触部5は、少なくとも一つの接触箇所で第二部材に接触可能に構成されている。接触部5は、平板部21と、突起23とを有する。平板部21は、図中でいう上面側が、自動実装機の吸引ノズルで吸着可能な吸着面になっていて、コンタクト1を自動実装機によって電子回路基板上に配置し、コンタクト1を電子回路基板上に表面実装することができる。 The contact portion 5 is configured to be able to contact the second member at at least one contact location. The contact portion 5 includes a flat plate portion 21 and a protrusion 23. The flat plate portion 21 has a suction surface that can be sucked by a suction nozzle of an automatic mounting machine on the upper surface side in the figure. The contact 1 is arranged on the electronic circuit board by the automatic mounting machine, and the contact 1 is placed on the electronic circuit board. Can be surface mounted on top.
 突起23は、第二部材側へ向かって突出しており、この突起23で第二部材に接触するように構成されている。すなわち、本実施形態の場合、上述の突起23によって、少なくとも一つの接触箇所の一つが構成される。本実施形態の場合、突起23の高さ(平板部21からの突出量。)は、0.15mm以上かつ0.35mm以下とされている(図には突起23の高さ0.3mmの場合を例示。)。 The protrusion 23 protrudes toward the second member side, and is configured to come into contact with the second member by the protrusion 23. That is, in the case of the present embodiment, one of at least one contact location is configured by the above-described protrusion 23. In the case of this embodiment, the height of the protrusion 23 (the amount of protrusion from the flat plate portion 21) is 0.15 mm or more and 0.35 mm or less (in the figure, the height of the protrusion 23 is 0.3 mm). For example.)
 また、突起23は、平板部21が曲げ部25から延び出る方向(図中でいう左右方向。)、及び平板部21における薄板の板厚方向(図中でいう上下方向。)の双方に対して直交する方向(図中でいう前後方向。)を、平板部21の幅方向として、平板部21の幅方向の中央に設けられている。これにより、突起23は、薄板の端面(平板部21の前後方向両端の端面。)から離れた位置に形成されている。しかも、突起23の表面には、薄板を貫通するような箇所がない。したがって、突起23の表面は、全体にわたって薄板が有するめっき膜(すずめっき膜。)で覆われた構造となっていて、薄板の母材金属(ばね用ベリリウム銅。)が露出していない構造になっている。 In addition, the protrusion 23 has both a direction in which the flat plate portion 21 extends from the bent portion 25 (the horizontal direction in the drawing) and a thickness direction of the thin plate in the flat plate portion 21 (the vertical direction in the drawing). The direction perpendicular to each other (the front-rear direction in the figure) is defined as the width direction of the flat plate portion 21, and is provided at the center in the width direction of the flat plate portion 21. Thereby, the protrusion 23 is formed in the position away from the end surface of the thin plate (end surfaces at both ends in the front-rear direction of the flat plate portion 21). In addition, the surface of the protrusion 23 does not have a portion that penetrates the thin plate. Therefore, the surface of the protrusion 23 is entirely covered with a plating film (tin plating film) that the thin plate has, and the thin base metal (beryllium copper for spring) is not exposed. It has become.
 ばね部7は、両端間が弾性変形可能に構成されている。ばね部7の一端は基部3に連なる固定端、ばね部7の他端は接触部5に連なる自由端とされ、これにより、ばね部7は、接触部5を変位可能に支持している。ばね部7において、接触部5に連なる部分には、薄板の板厚方向が径方向となる向きに湾曲した曲げ部25が設けられている。上述の平板部21は、曲げ部25の一端から平板状に延び出ている。すなわち、平板部21と曲げ部25との境界が、接触部5とばね部7との境界になっている。 The spring portion 7 is configured to be elastically deformable between both ends. One end of the spring portion 7 is a fixed end that is continuous with the base portion 3, and the other end of the spring portion 7 is a free end that is continuous with the contact portion 5, whereby the spring portion 7 supports the contact portion 5 in a displaceable manner. In the spring portion 7, a bent portion 25 that is curved in a direction in which the thickness direction of the thin plate is a radial direction is provided in a portion that continues to the contact portion 5. The flat plate portion 21 extends from one end of the bent portion 25 in a flat plate shape. That is, the boundary between the flat plate portion 21 and the bent portion 25 is the boundary between the contact portion 5 and the spring portion 7.
 2つの延出部9,9は、平板部21における幅方向(図中でいう前後方向。)の両端に設けられ、当該両端から湾曲して突起23の突出方向とは反対方向へと延び出ている。2つの立設壁11,11は、基部3から延び出て、ばね部7を挟んで両側(図中でいう前後方向両側。)となる位置に配置されている。係合片13は、平板部21における曲げ部25側とは反対側の端部から延び出ている。2つの立設壁11,11にはそれぞれ係合孔27が設けられ、当該係合孔27に係合片13が引っ掛かることにより、接触部5の可動範囲が規制されるように構成されている。 The two extending portions 9, 9 are provided at both ends of the flat plate portion 21 in the width direction (the front-rear direction in the drawing), and are bent from both ends to extend in a direction opposite to the protruding direction of the protrusion 23. ing. The two standing walls 11, 11 extend from the base portion 3 and are disposed at positions on both sides (both sides in the front-rear direction in the drawing) with the spring portion 7 interposed therebetween. The engaging piece 13 extends from the end portion of the flat plate portion 21 opposite to the bent portion 25 side. The two standing walls 11, 11 are each provided with an engagement hole 27, and the engagement piece 13 is caught in the engagement hole 27 so that the movable range of the contact portion 5 is restricted. .
  [冷熱衝撃試験]
 コンタクト1(実施例)と、突起23が無い点を除いて上述のコンタクト1と同様に構成されたコンタクト(比較例)を用いて、冷熱衝撃試験を実施した。具体的な試験手順としては、上述の各コンタクトと測定用端子を基板にはんだ付けした。その後、接触部5の接触対象となる第二部材としては金めっき銅板を使用し、金めっき銅板と接触部5を接触させた状態で板金間に固定して、供試品とした。
[Cool thermal shock test]
A thermal shock test was performed using the contact 1 (Example) and a contact (Comparative Example) configured in the same manner as the above-described contact 1 except that the protrusion 23 was not provided. As a specific test procedure, the above-described contacts and measurement terminals were soldered to the substrate. Thereafter, a gold-plated copper plate was used as the second member to be contacted with the contact portion 5, and the gold-plated copper plate and the contact portion 5 were brought into contact with each other and fixed between the metal plates to obtain a specimen.
 続いて、測定用端子と金めっき銅板間の初期の直流抵抗値を測定した後、供試品を市販の冷熱衝撃装置内に設置して、装置内の環境温度が交互に-40℃と150℃となる状態が繰り返されるように処理した。所定サイクル数の処理後には、冷熱衝撃装置から供試品を取り出して、測定用端子と金めっき銅板間の処理後の直流抵抗値(平均値、最大値、及び最小値)を測定した。試験結果を下記[表1]に示す。 Subsequently, after measuring the initial direct current resistance value between the measuring terminal and the gold-plated copper plate, the sample was placed in a commercially available thermal shock apparatus, and the ambient temperature in the apparatus was alternately -40 ° C and 150 ° C. It processed so that the state which became ° C might be repeated. After the predetermined number of cycles, the specimen was taken out of the thermal shock apparatus, and the DC resistance value (average value, maximum value, and minimum value) after the treatment between the measurement terminal and the gold-plated copper plate was measured. The test results are shown in [Table 1] below.
Figure JPOXMLDOC01-appb-T000001
 
 以上の試験の結果、突起23がある場合は、初期時点(0サイクル時点)で9mΩであった直流抵抗値の最大値が、250サイクル時点で12mΩまで僅かに上昇した。ただし、その後は、500サイクル時点で16mΩ、750サイクル時点で16mΩ、1000サイクル時点で16mΩと安定し、これ以上の大幅な抵抗値の上昇は見られなかった。
Figure JPOXMLDOC01-appb-T000001

As a result of the above test, when the protrusion 23 was present, the maximum DC resistance value that was 9 mΩ at the initial time point (0 cycle time) slightly increased to 12 mΩ at the 250th cycle time. However, after that, it was stabilized at 16 mΩ at 500 cycles, 16 mΩ at 750 cycles, and 16 mΩ at 1000 cycles, and no further increase in resistance value was observed.
 一方、突起23が無い場合は、初期時点(0サイクル時点)で8mΩであった直流抵抗値の最大値が、250サイクル時点で1005mΩまで急激に上昇した。その後、500サイクル時点では191mΩまで抵抗値が低下、750サイクル時点では279mΩまで抵抗値が上昇し、1000サイクル時点では1403mΩまで抵抗値が急激に上昇した。このことから、突起23が無い場合は、接触部5と第二部材との間で抵抗値が不安定に変動することが判明した。 On the other hand, when there was no protrusion 23, the maximum DC resistance value, which was 8 mΩ at the initial time point (0 cycle time), rapidly increased to 1005 mΩ at 250 time points. Thereafter, the resistance value decreased to 191 mΩ at 500 cycles, the resistance value increased to 279 mΩ at 750 cycles, and the resistance value increased rapidly to 1403 mΩ at 1000 cycles. From this, it was found that the resistance value fluctuates in an unstable manner between the contact portion 5 and the second member when there is no protrusion 23.
 ちなみに、コンタクトを第二部材(本実施形態では金めっき銅板。)と接触させない状態で、同様な熱処理を個々の部品に対して行った上で、その後にコンタクトと第二部材とを接触させて直流抵抗値を測定しても、その場合は、直流抵抗値はほとんど変化しない(+数mΩ~数十mΩ程度。)。これに対し、上述の試験のように、コンタクトを第二部材に接触させた状態の供試品に対して冷熱衝撃試験を実施すると、上述の試験結果のように直流抵抗値が増加する。このことから、上述の試験において突起23が無い場合に抵抗値が急激に上昇するのは、接触部5と第二部材との界面において異種金属接触腐食が発生し、電気抵抗値の高い成分が生成することに原因があるものと推察される。 By the way, after the same heat treatment is performed on each component in a state where the contact is not in contact with the second member (in this embodiment, a gold-plated copper plate), the contact is then brought into contact with the second member. Even if the DC resistance value is measured, in that case, the DC resistance value hardly changes (+ several mΩ to several tens mΩ). On the other hand, when the thermal shock test is performed on the specimen in which the contact is in contact with the second member as in the above-described test, the DC resistance value increases as in the above-described test result. From this, in the above test, when there is no protrusion 23, the resistance value rapidly increases because dissimilar metal contact corrosion occurs at the interface between the contact portion 5 and the second member, and a component having a high electrical resistance value is present. It is assumed that there is a cause in the generation.
 また、上昇した抵抗値が一時的に低下するのは、冷熱衝撃試験の過程で、温度変化に伴う膨張と収縮を繰り返すことにより、接触部5と第二部材とが擦れ合い、その結果、両者の界面に生成した電気抵抗値の高い成分が削られることに原因があるものと推察される。 Further, the increased resistance value temporarily decreases in the course of the thermal shock test, by repeating the expansion and contraction accompanying the temperature change, and the contact portion 5 and the second member rub against each other. It is inferred that the cause is that the component having a high electrical resistance value generated at the interface of the material is shaved.
 これに対し、突起23がある場合に抵抗値が殆ど上昇しないのは、突起23の先端で第二部材に接触しているため、異種金属接触腐食が発生する可能性のある範囲が狭く、しかも、接触圧が高くなるので、仮に腐食が発生しても突起23と第二部材が擦れ合えば、抵抗値の高い成分が削られやすく、電気抵抗値が上昇しにくいのではないかと推察される。 On the other hand, the resistance value hardly increases when the projection 23 is present because the tip of the projection 23 is in contact with the second member, and thus the range in which different metal contact corrosion may occur is narrow, Since the contact pressure increases, even if corrosion occurs, if the protrusion 23 and the second member rub against each other, it is presumed that the component having a high resistance value is likely to be scraped off and the electrical resistance value is unlikely to increase. .
 なお、第二部材の材質をアルミニウム合金に変更した場合についても、同様の傾向が見受けられ、突起23がある場合には抵抗値が殆ど上昇しないものの、突起23相当物がない場合には抵抗値が急激に上昇する傾向があった。 The same tendency can be seen when the material of the second member is changed to an aluminum alloy. The resistance value hardly increases when the projection 23 is present, but the resistance value when the projection 23 equivalent is not present. Tended to rise rapidly.
  [突起の位置]
 次に、突起23の位置について検証した。具体的には、疲労解析を実行可能なシミュレーションソフトウェアを用いて、突起23の位置を7通りに変更し、それら7通りの事例それぞれについて、コンタクトを上方から水平に圧縮した場合に、曲げ部25において発生する応力の大きさと、接触部5の振れ角度を検証した。なお、本実施形態の場合、シミュレーションソフトウェアとしては、SOLIDWORKS Simulation Premium(ダッソー・システムズ・ソリッドワークス社製)を利用した。
[Protrusion position]
Next, the position of the protrusion 23 was verified. Specifically, using simulation software capable of executing fatigue analysis, when the positions of the protrusions 23 are changed to seven ways, and the contacts are compressed horizontally from above for each of the seven cases, the bent portion 25 is obtained. The magnitude of the stress generated in step 1 and the deflection angle of the contact portion 5 were verified. In this embodiment, SOLIDWORKS Simulation Premium (manufactured by Dassault Systèmes Solid Works) was used as simulation software.
 突起23の位置については、接触部5とばね部7との境界から突起23までの距離X(以下、突起位置Xともいう。)を、下記表2に示す通りに変更した。また、突起23の高さについては、0.15mm、0.25mm、0.35mmの3通りを検証した。また、下記表2において、「ばね先端振れ角度(上側)」は、接触部5が振動する結果、接触部5がばね部7側から係合片13側へ上り勾配となる向きに傾いたときの最大角度、「ばね先端振れ角度(下側)」は、接触部5が振動する結果、接触部5がばね部7側から係合片13側へ下り勾配となる向きに傾いたときの最大角度である。これらの角度が大きいと、接触部5の振れが大きいことになり、これらの角度が0°であれば、接触部5が水平な状態から振れないことを意味する。以上の結果を表2に示す。 Regarding the position of the protrusion 23, the distance X from the boundary between the contact portion 5 and the spring portion 7 to the protrusion 23 (hereinafter also referred to as the protrusion position X) was changed as shown in Table 2 below. Moreover, about the height of the protrusion 23, three types, 0.15 mm, 0.25 mm, and 0.35 mm, were verified. In Table 2 below, “spring tip deflection angle (upper side)” means that when the contact portion 5 vibrates, the contact portion 5 is inclined upward from the spring portion 7 side to the engagement piece 13 side. Is the maximum when the contact portion 5 is tilted downward from the spring portion 7 side to the engagement piece 13 side as a result of the contact portion 5 vibrating. Is an angle. When these angles are large, the shake of the contact portion 5 is large, and when these angles are 0 °, it means that the contact portion 5 cannot swing from a horizontal state. The results are shown in Table 2.
Figure JPOXMLDOC01-appb-T000002
 
 上記検証結果からは、突起23の高さが0.15mm、0.25mm、0.35mmのいずれであっても、突起位置Xが0.7mm以下になると、「ばね先端振れ角度(上側)」が0よりも大となることがわかる。また、突起位置Xが0.9mm以上になると、「ばね先端振れ角度(上側)」が0となることがわかる。つまり、突起位置Xが0.9mm以上になると、接触部5は、ばね部7側から係合片13側へ上り勾配となる向きに傾く方向へは振れなくなる。
Figure JPOXMLDOC01-appb-T000002

From the above verification results, when the protrusion position X is 0.7 mm or less even if the height of the protrusion 23 is 0.15 mm, 0.25 mm, or 0.35 mm, the “spring tip deflection angle (upper side)” It can be seen that is greater than zero. It can also be seen that when the projection position X is 0.9 mm or more, the “spring tip deflection angle (upper side)” becomes zero. That is, when the protrusion position X is 0.9 mm or more, the contact portion 5 does not swing in a direction inclined to an upward gradient from the spring portion 7 side to the engagement piece 13 side.
 図4A,図4B,図4Cは、突起位置Xと発生応力との関係を示すグラフである。このグラフから明らかなように、突起位置Xが0.9mmから2.7mmの範囲内にある場合は、発生応力が極端に大きくは変動しないものの、突起位置Xが0.7mm以下になると、発生応力が急激に上昇することがわかる。 4A, 4B, and 4C are graphs showing the relationship between the protrusion position X and the generated stress. As is apparent from this graph, when the projection position X is within the range of 0.9 mm to 2.7 mm, the generated stress does not vary extremely, but it occurs when the projection position X is 0.7 mm or less. It can be seen that the stress increases rapidly.
 つまり、突起位置Xが0.7mm以下になると、接触部5に振動が伝わった際に、接触部5は水平位置に対して上下に振れるようになり、かつ、発生応力も相対的に大きくなる。これに対し、突起位置Xが0.9mm以上になると、接触部5に振動が伝わった際に、接触部5は水平位置から下向きにしか振れず、かつ、発生応力も相対的に小さくなる。すなわち、突起位置X=0.9mmを境にして、応力の発生傾向が変わる。 That is, when the projection position X is 0.7 mm or less, when vibration is transmitted to the contact portion 5, the contact portion 5 can swing up and down with respect to the horizontal position, and the generated stress becomes relatively large. . On the other hand, when the projection position X is 0.9 mm or more, when vibration is transmitted to the contact portion 5, the contact portion 5 can only swing downward from the horizontal position, and the generated stress becomes relatively small. That is, the stress generation tendency changes at the projection position X = 0.9 mm.
 したがって、ばね部7の破損リスクを低減するには、突起位置Xを0.9mm以上に設定することが有効である。なお、突起位置Xを上述の7通りの位置に変化させてもZ特性には変化がなく、突起位置Xをいずれの位置に設定しても、EMC対策効果については一定の効果が認められた。 Therefore, in order to reduce the risk of breakage of the spring portion 7, it is effective to set the projection position X to 0.9 mm or more. In addition, even if the projection position X is changed to the above seven positions, the Z characteristic does not change, and no matter what the projection position X is set, a certain effect is recognized as an EMC countermeasure effect. .
  [効果]
 以上説明したとおり、上記コンタクト1によれば、接触部5は、上述のような突起23の先端で第二部材に接触する。そのため、このような突起23が設けられていない場合に比べ、小さな接触箇所でコンタクト1を第二部材に接触させることができる。したがって、突起23のない大きな接触面で第二部材に接触するコンタクト1に比べ、接触圧を高めることができ、これにより、接触箇所に酸素や水等が入り込むのを抑制できるので、腐食が発生するのを抑制できる。また、いくらか腐食が発生したとしても、小さな接触箇所で発生した腐食であれば、突起23と第二の部材が擦れ合うことで腐食箇所が成長する前に腐食箇所を削り落とすことができる。よって、これらの作用により、腐食箇所が拡がるのを抑制でき、コンタクト1と第二部材との間において抵抗値が上がるのを抑制することができる。
[effect]
As described above, according to the contact 1, the contact portion 5 contacts the second member at the tip of the protrusion 23 as described above. Therefore, the contact 1 can be brought into contact with the second member at a small contact location as compared with the case where such a protrusion 23 is not provided. Accordingly, the contact pressure can be increased as compared with the contact 1 that contacts the second member with a large contact surface without the protrusion 23, thereby suppressing the entry of oxygen, water, or the like into the contact portion, thereby causing corrosion. Can be suppressed. Even if some corrosion occurs, if the corrosion occurs at a small contact location, the corrosion location can be scraped off before the corrosion location grows by rubbing the projection 23 and the second member. Therefore, by these actions, it is possible to suppress the expansion of the corrosion site, and it is possible to suppress the resistance value from increasing between the contact 1 and the second member.
 さらに、上述のような突起23は、接触部5とばね部7との境界から接触部5側へ0.9mm以上離れた位置に設けられている。そのため、接触部5とばね部7との境界から接触部5側へ0.9mm未満しか離れていない位置に同様な突起23が設けられている場合に比べ、平板部21が突起23を支点にしてシーソーのように上下に揺動するのを抑制できる。これにより、接触部5とばね部7との境界付近に作用する応力が過大になるのを抑制することができ、ばね部7が破損するのを抑制することができる。したがって、例えば車載機器のように、振動が伝わる環境においてコンタクト1が使用されたとしても、長期にわたってばね部7が破断するのを抑制でき、コンタクト1を有効に機能させることができる。 Furthermore, the projection 23 as described above is provided at a position 0.9 mm or more away from the boundary between the contact portion 5 and the spring portion 7 toward the contact portion 5 side. Therefore, the flat plate portion 21 uses the projection 23 as a fulcrum as compared with the case where a similar projection 23 is provided at a position that is less than 0.9 mm away from the boundary between the contact portion 5 and the spring portion 7 toward the contact portion 5 side. Therefore, it can be suppressed to swing up and down like a seesaw. Thereby, it can suppress that the stress which acts on the boundary vicinity of the contact part 5 and the spring part 7 becomes excessive, and can suppress that the spring part 7 is damaged. Therefore, even if the contact 1 is used in an environment where vibration is transmitted, for example, in a vehicle-mounted device, the spring portion 7 can be prevented from breaking for a long period of time, and the contact 1 can function effectively.
 また、上記コンタクト1の場合、外形寸法が2mm×2mm×2mm以上とされているので、外形寸法が過剰に小さいコンタクト1に比べ、第一部材に対して容易に固定することができる。また、外形寸法が10mm×10mm×10mm以下とされているので、外形寸法が過剰に大きいコンタクト1とは異なり、狭い領域であっても容易に配置することができる。 Further, in the case of the contact 1, since the outer dimension is set to 2 mm × 2 mm × 2 mm or more, it can be easily fixed to the first member as compared with the contact 1 whose outer dimension is excessively small. Further, since the outer dimension is set to 10 mm × 10 mm × 10 mm or less, unlike the contact 1 whose outer dimension is excessively large, it can be easily arranged even in a narrow region.
 また、上記コンタクト1の場合、突起23の高さが0.15mm以上とされているので、突起23を有効に機能させて腐食の発生を抑制することができ、コンタクト1と第二部材との間の抵抗値が上がるのを抑制することができる。しかも、突起23の高さが0.35mm以下であるので、ばね部7に過大な負荷がかかる可能性を低減することができる。 In the case of the contact 1, since the height of the protrusion 23 is 0.15 mm or more, the protrusion 23 can function effectively to suppress the occurrence of corrosion. It is possible to suppress an increase in resistance value. And since the height of the protrusion 23 is 0.35 mm or less, possibility that an excessive load will be applied to the spring part 7 can be reduced.
 また、上記コンタクト1の場合、薄板の板厚が0.10mm以上であるので、板厚が0.1mm未満である場合に比べ、ばね部7の弾性を適正に確保することができる。加えて、ばね部7以外の部分で適度な剛性を確保することができる。また、薄板の板厚が0.15mm以下であるので、板厚が0.15mm超過である場合に比べ、ばね部7の剛性か過剰に高くなるのを抑制することができる。 Further, in the case of the contact 1, since the plate thickness of the thin plate is 0.10 mm or more, the elasticity of the spring portion 7 can be appropriately ensured as compared with the case where the plate thickness is less than 0.1 mm. In addition, moderate rigidity can be secured at portions other than the spring portion 7. Moreover, since the plate | board thickness of a thin plate is 0.15 mm or less, compared with the case where plate | board thickness exceeds 0.15 mm, it can suppress that the rigidity of the spring part 7 becomes high too much.
 また、上記コンタクト1の場合、上述のような2つの延出部9,9により、平板部21を挟んで第二部材とは反対側となる位置に異物が入り込むのを抑制することができる。したがって、そのような異物が接触部5に引っ掛かることや、引っ掛かった異物によって接触部5が引き起こされてしまうのを抑制することができる。また、平板部21の幅方向両端に2つの延出部9,9が設けられている場合、2つの延出部9,9が設けられていない場合に比べると、平板部21の曲げ剛性を向上させることができる。そのような曲げ剛性の高い平板部21に突起23が設けられていれば、突起23を第二部材に対してより強く押し当てることができ、腐食の発生を抑制する効果を向上させることができる。 Further, in the case of the contact 1, the two extending portions 9 and 9 as described above can prevent foreign matter from entering a position opposite to the second member with the flat plate portion 21 interposed therebetween. Therefore, it can suppress that such a foreign material is caught by the contact part 5, and that the contact part 5 is caused by the caught foreign material. Further, when the two extending portions 9 and 9 are provided at both ends in the width direction of the flat plate portion 21, the bending rigidity of the flat plate portion 21 is higher than that in the case where the two extending portions 9 and 9 are not provided. Can be improved. If the flat plate portion 21 having such a high bending rigidity is provided with the protrusion 23, the protrusion 23 can be pressed more strongly against the second member, and the effect of suppressing the occurrence of corrosion can be improved. .
 また、上記コンタクト1の場合、接触部5を引き起こすような外力が接触部5に作用したとしても、そのような場合には、2つの立設壁11,11それぞれに設けられた係合孔27に係合片13が引っ掛かることにより、接触部5の可動範囲が規制される。したがって、接触部5が過剰に引き起こされてしまうのを抑制することができる。また、係合片13が2つの立設壁11,11のそれぞれの係合孔27に係合することにより、基部3と接触部5が相対的に捻れる方向へ変位するのも抑制される。その結果、ばね部7に捻れが発生するのを抑制することができ、ばね部7の破損リスクを低減することができる。 In the case of the contact 1, even if an external force that causes the contact portion 5 acts on the contact portion 5, in such a case, the engagement holes 27 provided in the two standing walls 11 and 11 respectively. When the engagement piece 13 is hooked on the movable portion 13, the movable range of the contact portion 5 is restricted. Therefore, it can suppress that the contact part 5 is caused excessively. Further, the engagement piece 13 is engaged with the engagement holes 27 of the two standing walls 11 and 11, so that the base 3 and the contact portion 5 are also prevented from being displaced in a relatively twisting direction. . As a result, the occurrence of twisting in the spring portion 7 can be suppressed, and the risk of damage to the spring portion 7 can be reduced.
 また、上記コンタクト1の場合、突起23の表面がめっき膜で覆われているので、コンタクト1の母材金属よりも、第二部材との電位差が小さくなるような金属種でめっき膜を構成することが可能である。この場合、めっき膜が設けられていない場合に比べ、突起23と第二の部材との間で腐食が発生するのを抑制することができる。 In the case of the contact 1, since the surface of the protrusion 23 is covered with a plating film, the plating film is made of a metal species that has a smaller potential difference from the second member than the base metal of the contact 1. It is possible. In this case, it is possible to suppress the occurrence of corrosion between the protrusion 23 and the second member as compared with the case where no plating film is provided.

  [補足]
 なお、以上説明した例示的な実施形態から明らかなように、本開示のコンタクトは、更に以下に挙げるような構成を備えていてもよい。
[Supplement]
As is clear from the exemplary embodiments described above, the contact according to the present disclosure may further include the following configurations.
 まず、本開示のコンタクトは、外形寸法が2mm×2mm×2mm以上かつ10mm×10mm×10mm以下の範囲内に収まる形状に構成されていてもよい。このように構成されたコンタクトによれば、外形寸法が2mm×2mm×2mm以上とされているので、外形寸法が過剰に小さいコンタクトに比べ、第一部材に対して容易に固定することができる。また、外形寸法が10mm×10mm×10mm以下とされているので、外形寸法が過剰に大きいコンタクトとは異なり、狭い領域であっても容易に配置することができる。 First, the contact according to the present disclosure may be configured to have a shape that fits in the range of 2 mm × 2 mm × 2 mm or more and 10 mm × 10 mm × 10 mm or less. According to the contact configured as described above, since the outer dimension is 2 mm × 2 mm × 2 mm or more, the contact can be easily fixed to the first member as compared with the contact having an excessively small outer dimension. Further, since the outer dimension is 10 mm × 10 mm × 10 mm or less, unlike a contact having an excessively large outer dimension, it can be easily arranged even in a narrow region.
 また、本開示のコンタクトにおいて、突起の高さが、0.15mm以上かつ0.35mm以下に構成されていてもよい。このように構成されたコンタクトによれば、突起の高さが0.15mm以上とされているので、突起を有効に機能させて腐食の発生を抑制することができ、コンタクトと第二部材との間の抵抗値が上がるのを抑制することができる。しかも、突起の高さが0.35mm以下とされているので、ばね部に過大な負荷がかかる可能性を低減することができる。 Further, in the contact of the present disclosure, the height of the protrusion may be configured to be 0.15 mm or more and 0.35 mm or less. According to the contact configured as described above, since the height of the protrusion is 0.15 mm or more, the protrusion can be effectively functioned to suppress the occurrence of corrosion. It is possible to suppress an increase in resistance value. Moreover, since the height of the protrusion is 0.35 mm or less, the possibility that an excessive load is applied to the spring portion can be reduced.
 また、本開示のコンタクトにおいて、平板部が曲げ部から延び出る方向、及び平板部における薄板の板厚方向の双方に対して直交する方向を、平板部の幅方向として、平板部における幅方向の両端には、当該両端から湾曲して突起の突出方向とは反対方向へと延び出る延出部が設けられていてもよい。このように構成されたコンタクトによれば、上述のような延出部により、平板部を挟んで第二部材とは反対側となる位置に異物が入り込むのを抑制することができる。 Further, in the contact of the present disclosure, the direction perpendicular to both the direction in which the flat plate portion extends from the bent portion and the thickness direction of the thin plate in the flat plate portion is defined as the width direction of the flat plate portion, in the width direction of the flat plate portion. At both ends, an extending portion that curves from the both ends and extends in a direction opposite to the protruding direction of the protrusion may be provided. According to the contact configured as described above, the extension portion as described above can prevent foreign matter from entering a position opposite to the second member across the flat plate portion.
 したがって、そのような異物が接触部に引っ掛かることや、引っ掛かった異物によって接触部が引き起こされてしまうのを抑制することができる。また、平板部の幅方向両端に延出部が設けられているので、同様な延出部が設けられていない場合に比べると、平板部の曲げ剛性を向上させることができる。したがって、そのような曲げ剛性の高い平板部に突起が設けられていれば、突起を第二部材に対してより強く押し当てることができ、腐食の発生を抑制する効果を向上させることができる。 Therefore, it is possible to prevent such foreign matter from being caught on the contact portion and causing the contact portion to be caused by the caught foreign matter. Moreover, since the extension part is provided in the width direction both ends of the flat plate part, the bending rigidity of a flat plate part can be improved compared with the case where the similar extension part is not provided. Therefore, if the projection is provided on the flat plate portion having such a high bending rigidity, the projection can be pressed more strongly against the second member, and the effect of suppressing the occurrence of corrosion can be improved.
 また、本開示のコンタクトにおいて、基部から延び出る立設壁と、平板部における曲げ部側とは反対側の端部から延び出る係合片とを有し、立設壁には係合孔が設けられ、当該係合孔に係合片が引っ掛かることにより、接触部の可動範囲が規制されるように構成されていてもよい。このように構成されたコンタクトによれば、例えば、接触部を引き起こすような外力が接触部に作用したとしても、そのような場合には、立設壁に設けられた係合孔に係合片が引っ掛かることにより、接触部の可動範囲が規制される。 Further, the contact of the present disclosure has a standing wall extending from the base portion and an engagement piece extending from an end portion of the flat plate portion opposite to the bent portion side, and the standing wall has an engagement hole. It may be configured so that the movable range of the contact portion is restricted by the engagement piece being caught in the engagement hole. According to the contact configured as described above, for example, even if an external force that causes the contact portion acts on the contact portion, in such a case, the engagement piece is inserted into the engagement hole provided in the standing wall. As a result, the movable range of the contact portion is regulated.
 したがって、接触部が過剰に引き起こされてしまうのを抑制することができる。また、係合片が立設壁の係合孔に係合することにより、基部と接触部が相対的に捻れる方向へ変位するのも抑制される。その結果、ばね部に捻れが発生するのを抑制することができ、ばね部の破損リスクを低減することができる。 Therefore, it is possible to suppress the contact portion from being excessively caused. Further, when the engagement piece engages with the engagement hole of the standing wall, displacement of the base portion and the contact portion in a relatively twisting direction is also suppressed. As a result, the occurrence of twisting in the spring portion can be suppressed, and the risk of breakage of the spring portion can be reduced.
