Description

本発明は、バネ性と導電率を共に向上させる電気コンタクト及びメス端子に関する。   The present invention relates to an electrical contact and a female terminal that improve both springiness and electrical conductivity.

電気コネクタの一種として、メス接触子の内部に電気コンタクトを収容したメス端子がある。このメス端子に対してケーブル端末やＩＣピンなどのオス接触子を嵌合・固定させることで電気的接続と機械的固定が図られる。   One type of electrical connector is a female terminal that houses an electrical contact inside a female contact. Electrical connection and mechanical fixation can be achieved by fitting and fixing a male contact such as a cable terminal or IC pin to the female terminal.

図６に示したメス端子は、メス接触子６３が円筒形のもので、長手方向（＝軸方向）の一端がオス接触子６５を挿入する開口となっており、その開口に続く中空部６２に電気コンタクト６１が収容される。   In the female terminal shown in FIG. 6, the female contact 63 has a cylindrical shape, and one end in the longitudinal direction (= axial direction) is an opening into which the male contact 65 is inserted, and a hollow portion 62 following the opening. An electrical contact 61 is accommodated in the housing.

電気コンタクト６１は、メス接触子６３の内周に接触するべく外側に突き出た外側接触部６４と、上記中空部に挿入されるオス接触子６５の外周に接触するべく内側に突き出た内側接触部６６とを有する。また、電気コンタクト６１は、外側接触部６４がメス接触子６３の内周に接触し、内側接触部６６がオス接触子６５の外周に接触したときに、両接触部の接触により変形して接触圧を生じる応力変形部６７を有する。   The electrical contact 61 includes an outer contact portion 64 protruding outward to contact the inner periphery of the female contact 63 and an inner contact portion protruding inward to contact the outer periphery of the male contact 65 inserted into the hollow portion. 66. Further, when the outer contact portion 64 contacts the inner periphery of the female contact 63 and the inner contact portion 66 contacts the outer periphery of the male contact 65, the electrical contact 61 is deformed and contacted by the contact of both contact portions. It has the stress deformation part 67 which produces a pressure.

これにより、オス接触子６５をメス接触子６３に挿入すると、外側接触部６４がメス接触子６３に対し、内側接触部６６がオス接触子６５に対して、それぞれ接触圧をもって接触することになるので、接触抵抗が低く、接触不良が生じにくい良好な電気的接続が図られる。   Accordingly, when the male contact 65 is inserted into the female contact 63, the outer contact portion 64 contacts the female contact 63 and the inner contact portion 66 contacts the male contact 65 with contact pressure. As a result, a good electrical connection with low contact resistance and less prone to contact failure is achieved.

従来、電気コンタクト６１は単一の材料で作られている。その材料には接触圧の強さを示すバネ性と抵抗の低さを示す導電率の２つの性質が共に優れた材料が選定される。   Conventionally, the electrical contact 61 is made of a single material. As the material, a material excellent in both of the two properties of spring property indicating the strength of contact pressure and conductivity indicating low resistance is selected.

大電流に対応するためには、電気コンタクトのバネ力を強めることにより、両接触部の接触圧を高めて接触抵抗を低減すると共に、安定的な電気的接触を確保する必要がある。また、その一方で、電気コンタクトの導電率を高めることにより、電気コンタクトの発熱を抑制する必要がある。   In order to cope with a large current, it is necessary to increase the contact pressure of both contact portions by increasing the spring force of the electrical contacts to reduce the contact resistance and to ensure stable electrical contact. On the other hand, it is necessary to suppress heat generation of the electrical contact by increasing the electrical conductivity of the electrical contact.

しかし、従来、電気コンタクトに使用される材料であるベリリウム銅やリン青銅は導電率が約５０％ＩＡＣＳ以下と低く、しかも、バネ性を上げるほど導電率が下がる傾向にある。したがって、従来の電気コンタクトは、バネ性と導電率を共に向上させることが困難である。   However, conventionally, beryllium copper and phosphor bronze, which are materials used for electrical contacts, have a conductivity as low as about 50% IACS or less, and the conductivity tends to decrease as the spring property increases. Therefore, it is difficult for conventional electrical contacts to improve both springiness and electrical conductivity.

また、ブレードの個数を増やすことにより接触箇所を多くして接触抵抗を小さくすると、ブレードの個数が増えて電気コンタクトの径が大きくなるので、好ましくない。   In addition, increasing the number of blades to increase the number of contact points to reduce the contact resistance is not preferable because the number of blades increases and the diameter of the electrical contact increases.

そこで、本発明の目的は、上記課題を解決し、バネ性と導電率を共に向上させる電気コンタクト及びメス端子を提供することにある。   Therefore, an object of the present invention is to provide an electrical contact and a female terminal that solve the above-described problems and improve both spring property and electrical conductivity.

上記目的を達成するために本発明の電気コンタクトは、開口された中空部を有するメス接触子の内周に接触するべく外側に突き出た外側接触部と、上記中空部に挿入されるオス接触子の外周に接触するべく内側に突き出た内側接触部と、両接触部の接触により変形して接触圧を生じる応力変形部とを有する電気コンタクトにおいて、上記外側接触部と上記内側接触部は、導電材料とバネ材料とが張り合わされたクラッド構造を有するものである。   In order to achieve the above object, an electrical contact according to the present invention includes an outer contact portion protruding outward to contact the inner periphery of a female contact having an open hollow portion, and a male contact inserted into the hollow portion. An electrical contact having an inner contact portion projecting inward to contact the outer periphery of the wire and a stress deforming portion that deforms due to contact between the two contact portions to generate contact pressure, wherein the outer contact portion and the inner contact portion are electrically conductive. It has a clad structure in which a material and a spring material are bonded together.

上記クラッド構造は、上記バネ材料の内外両面にそれぞれ上記導電材料が張り合わされた構造であってもよい。   The clad structure may be a structure in which the conductive material is bonded to both the inner and outer surfaces of the spring material.

応力変形部は、バネ材料のみからなってもよい。   The stress deforming portion may be made of only the spring material.

オス接触子の挿入方向に沿って長く伸び、その長手方向の両端で幅が狭く、中間部分で幅が広い複数のブレードが形成され、該ブレードが両端を軸にして捩られることにより、該両端に上記応力変形部が形成され、該ブレードの中間部分の両縁に上記外側接触部と上記内側接触部が形成されてもよい。   A plurality of blades that extend long along the insertion direction of the male contact, are narrow at both ends in the longitudinal direction, and wide at the middle portion, and are twisted around the both ends to form both ends. The stress deforming portion may be formed on both sides of the blade, and the outer contact portion and the inner contact portion may be formed on both edges of the intermediate portion of the blade.

上記導電材料が銅又は銅合金であり、上記バネ材料がステンレスであってもよい。   The conductive material may be copper or a copper alloy, and the spring material may be stainless steel.

また、本発明のメス端子は、上記いずれかの電気コンタクトがメス接触子の内部に配置されたものである。   In the female terminal of the present invention, any one of the electrical contacts described above is disposed inside the female contact.

本発明は次の如き優れた効果を発揮する。   The present invention exhibits the following excellent effects.

（１）バネ性と導電率を共に向上させることができる。   (1) Both springiness and electrical conductivity can be improved.

以下、本発明の一実施形態を添付図面に基づいて詳述する。   Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

図１〜図４に示されるように、本発明に係る電気コンタクト１は、開口された中空部２を有するメス接触子３の内周に接触するべく外側に突き出た外側接触部４と、中空部２に挿入されるオス接触子５の外周に接触するべく内側に突き出た内側接触部６と、両接触部４，６の接触により変形して接触圧を生じる応力変形部７とを有する電気コンタクト１において、外側接触部４と内側接触部６は、導電材料８とバネ材料９とが張り合わされたクラッド構造１０（図４参照）を有するものである。   As shown in FIGS. 1 to 4, an electrical contact 1 according to the present invention includes an outer contact portion 4 that protrudes outward to contact the inner periphery of a female contact 3 having an open hollow portion 2, and a hollow Electricity having an inner contact portion 6 projecting inward to contact the outer periphery of the male contact 5 inserted into the portion 2, and a stress deforming portion 7 that is deformed by the contact of both the contact portions 4 and 6 to generate a contact pressure. In the contact 1, the outer contact portion 4 and the inner contact portion 6 have a clad structure 10 (see FIG. 4) in which a conductive material 8 and a spring material 9 are bonded together.

この実施形態では、導電材料８が覆っている領域部分がクラッド構造１０になっており、これを除く領域は、バネ材料９の単一層構造になっている。   In this embodiment, the region covered with the conductive material 8 has a clad structure 10, and the other region has a single layer structure of the spring material 9.

メス端子１１は、電気コンタクト１がメス接触子３の内部に配置されたものである。メス接触子３が円筒形に形成されており、長手方向（＝軸方向、オス接触子５の挿入方向）の一端がオス接触子５を挿入する開口１２となっており、その開口に続く中空部２に電気コンタクト１が収容される。一方、オス接触子５は、円柱形に形成され、挿入方向先端にテーパを有する。   The female terminal 11 is one in which the electrical contact 1 is disposed inside the female contact 3. The female contact 3 is formed in a cylindrical shape, and one end in the longitudinal direction (= axial direction, insertion direction of the male contact 5) is an opening 12 into which the male contact 5 is inserted. The electrical contact 1 is accommodated in the part 2. On the other hand, the male contact 5 is formed in a cylindrical shape and has a taper at the tip in the insertion direction.

電気コンタクト１は、オス接触子５の挿入方向を長手方向とする概略円筒形のかご状に形成され、長手方向両端に位置する環状部１３と、両環状部１３，１３間に長く形成された複数のスリット１４と複数のブレード１５を有する。詳しく述べると、環状部１３は、ブレード１５の両端を支持することにより、電気コンタクト１全体を概略円筒形のかご状に支持するものである。スリット１４は、長手方向の両端で幅が広く、中間部分で幅が狭くなっている。ブレード１５は、スリット１４が形成されたことによりスリット１４，１４間に残った部分を捩って形成したものである。   The electrical contact 1 is formed in a substantially cylindrical cage shape with the insertion direction of the male contact 5 as the longitudinal direction, and is formed long between the annular portions 13 located at both ends in the longitudinal direction and the annular portions 13 and 13. A plurality of slits 14 and a plurality of blades 15 are provided. More specifically, the annular portion 13 supports the both ends of the blade 15 to support the entire electrical contact 1 in a generally cylindrical cage shape. The slit 14 is wide at both ends in the longitudinal direction and narrow at the middle portion. The blade 15 is formed by twisting the portion remaining between the slits 14 and 14 due to the formation of the slits 14.

ブレード１５は、オス接触子５の挿入方向に沿って長く伸び、その長手方向の両端で幅が狭くくびれており、中間部分で幅が広く形成されたものであり、さらに、このブレード１５が両端を軸にして捩られることにより、該両端に応力変形部７が形成され、該ブレード１５の中間部分の両縁に外側接触部４と内側接触部６が形成される。このようなブレード１５の集合をルーバーと呼ぶ。   The blade 15 extends long along the insertion direction of the male contact 5, has a narrow width at both ends in the longitudinal direction, and has a wide width at the middle portion. As a result, the stress deformed portions 7 are formed at both ends, and the outer contact portion 4 and the inner contact portion 6 are formed at both edges of the intermediate portion of the blade 15. Such a set of blades 15 is called a louver.

ブレード１５は、電気コンタクト１の周方向にスリット１４を隔てて一定間隔で配置されている。各ブレード１５が環状部１３に繋がる両端を軸にして捩り加工されることで、両端の幅が狭い部分が捩れて応力変形部７となる。ブレード１５の中間部分は、両縁が径方向外方と内方に突き出して、外側接触部４と内側接触部６になる。   The blades 15 are arranged at regular intervals with a slit 14 in the circumferential direction of the electrical contact 1. Each blade 15 is twisted around both ends connected to the annular portion 13, so that a portion having a narrow width at both ends is twisted to form the stress deformed portion 7. The intermediate portion of the blade 15 has both edges projecting radially outward and inward to form the outer contact portion 4 and the inner contact portion 6.

図４に示されるように、ブレード１５は、環状部１３よりも径方向外方に突き出した外側接触部４と環状部よりも径方向内方に突き出した内側接触部６とを有する。なお、図４は、外力が加わらない状態を示している。応力変形部７は、外力が加わらないときに外側接触部４と内側接触部６が図示のように内外に突き出しているように、捩り加工される。   As shown in FIG. 4, the blade 15 has an outer contact portion 4 protruding radially outward from the annular portion 13 and an inner contact portion 6 protruding radially inward from the annular portion. FIG. 4 shows a state where no external force is applied. The stress deforming portion 7 is twisted so that when the external force is not applied, the outer contact portion 4 and the inner contact portion 6 protrude inward and outward as illustrated.

この実施形態では、外側接触部４及び内側接触部６は、ブレード１５の最縁部分１６から所定幅までが捩り加工方向と逆方向に湾曲加工されている。これにより、最も径方向外方に突き出た箇所及び最も径方向内方に突き出た箇所は、それぞれ最縁部分１６ではなく、湾曲の中央部分１７に位置する。したがって、外側接触部４は、湾曲の中央部分１７において外側表面がメス接触子３の内周に接触し、内側接触部６は、湾曲の中央部分１７において内側表面がオス接触子５の外周に接触することになる。   In this embodiment, the outer contact portion 4 and the inner contact portion 6 are curved in the direction opposite to the twisting direction from the outermost edge portion 16 of the blade 15 to a predetermined width. As a result, the most radially outwardly protruding portion and the most radially outwardly protruding portion are not located at the outermost edge portion 16 but at the central portion 17 of the curve. Accordingly, the outer contact portion 4 has an outer surface in contact with the inner periphery of the female contact 3 at the curved central portion 17, and the inner contact portion 6 has an inner surface on the outer periphery of the male contact 5 in the curved central portion 17. Will be in contact.

外側接触部４と内側接触部６は、導電材料８とバネ材料９とが張り合わされたクラッド構造を有する。ここでは、クラッド構造１０は、バネ材料９の両面にそれぞれ導電材料８が張り合わされた３重クラッド構造である。一方、応力変形部７は、バネ材料９のみからなる単一層構造である。   The outer contact portion 4 and the inner contact portion 6 have a clad structure in which a conductive material 8 and a spring material 9 are bonded together. Here, the clad structure 10 is a triple clad structure in which the conductive material 8 is bonded to both surfaces of the spring material 9. On the other hand, the stress deformed portion 7 has a single layer structure made of only the spring material 9.

この実施形態では、ブレード１５の中間部分は、全幅にわたり３重クラッド構造となっている。   In this embodiment, the intermediate portion of the blade 15 has a triple cladding structure over the entire width.

導電材料８としては銅又は銅合金がある。バネ材料９としてはステンレスがある。よって、ブレード１５は、環状部１３に繋がる応力変形部７がバネ材料９のみからなり、外側接触部４と内側接触部６を含む中間部分が導電材料８、バネ材料９、導電材料８の３重クラッド構造１０となる。   The conductive material 8 includes copper or a copper alloy. The spring material 9 is stainless steel. Therefore, in the blade 15, the stress deforming portion 7 connected to the annular portion 13 is made of only the spring material 9, and the intermediate portion including the outer contact portion 4 and the inner contact portion 6 is the conductive material 8, the spring material 9, and the conductive material 8. The heavy cladding structure 10 is obtained.

導電材料８は、導電率が６０％ＩＡＣＳ以上であるものがよい。バネ材料９は、０．２％耐力が６００ＭＰａ以上のものがよい。例えば、バネ材料９に厚さ０．１８μｍのＳＵＳ３０４、導電材料８に厚さ０．０４μｍのＣ１０２０を用いてブレード１５を形成すると、従来技術で電気コンタクト全体を厚さ０．２μｍのベリリウム銅（Ｃ１０２０）で形成した場合に比べると、応力変形部７におけるバネ性がほぼ同等で、外側接触部４及び内側接触部６における接触抵抗が低くできる。   The conductive material 8 preferably has a conductivity of 60% IACS or higher. The spring material 9 preferably has a 0.2% proof stress of 600 MPa or more. For example, when the blade 15 is formed using SUS304 having a thickness of 0.18 μm for the spring material 9 and C1020 having a thickness of 0.04 μm for the conductive material 8, the beryllium copper ( Compared with the case formed by C1020), the spring property in the stress deformed portion 7 is substantially equal, and the contact resistance in the outer contact portion 4 and the inner contact portion 6 can be lowered.

外側接触部４及び内側接触部６は、導電材料の層の表面にＳｎめっき等のめっきを施すとよい。   The outer contact portion 4 and the inner contact portion 6 may be plated with Sn plating or the like on the surface of the conductive material layer.

次に、本発明の作用効果を説明する。   Next, the function and effect of the present invention will be described.

図１に示されるように、メス接触子３の中空部２にオス接触子５が挿入されると、オス接触子５は電気コンタクト１の一端からその内部に挿入される。このとき、電気コンタクト１では、外側に突き出た外側接触部４がメス接触子３の内周に接触すると共に、内側に突き出た内側接触部６がオス接触子５の外周に接触する。各ブレード１５は、メス接触子３及びオス接触子５からそれぞれ径方向の力を受けるため、ブレード１５ごとの軸回りに捩りの力を受け、応力変形部７が応力変形する。   As shown in FIG. 1, when the male contact 5 is inserted into the hollow portion 2 of the female contact 3, the male contact 5 is inserted into one end of the electrical contact 1. At this time, in the electrical contact 1, the outer contact portion 4 protruding outward contacts the inner periphery of the female contact 3, and the inner contact portion 6 protruding inward contacts the outer periphery of the male contact 5. Since each blade 15 receives a radial force from each of the female contact 3 and the male contact 5, the blade 15 receives a torsional force around the axis of each blade 15, and the stress deforming portion 7 undergoes stress deformation.

図５に示されるように、外側接触部４の外側表面がメス接触子３の内周に接触すると共に、内側接触部６の内側表面がオス接触子５の外周に接触する。図４の外力なしの状態に比べて、図５の状態では、ブレード１５は、メス接触子３から径方向内向きの力を受け、オス接触子５から径方向外向きの力を受ける。よって、ブレード１５は捩りの力を受け、応力変形部７が応力変形する。   As shown in FIG. 5, the outer surface of the outer contact portion 4 contacts the inner periphery of the female contact 3, and the inner surface of the inner contact portion 6 contacts the outer periphery of the male contact 5. In the state of FIG. 5, the blade 15 receives a radially inward force from the female contact 3 and a radially outward force from the male contact 5 in the state of FIG. Therefore, the blade 15 receives a twisting force, and the stress deforming portion 7 undergoes stress deformation.

外側接触部４の外側表面が導電材料８であって導電率が高いため、応力変形部７の変形による外側接触部４の押し付けにより、メス接触子３との接触抵抗が低減する。同様に、内側接触部６の内側表面が導電材料８であって導電率が高いため、応力変形部７の変形による内側接触部６の押し付けにより、オス接触子５との接触抵抗が低減する。   Since the outer surface of the outer contact portion 4 is the conductive material 8 and has high conductivity, the contact resistance with the female contact 3 is reduced by pressing the outer contact portion 4 due to the deformation of the stress deformable portion 7. Similarly, since the inner surface of the inner contact portion 6 is the conductive material 8 and has high conductivity, the contact resistance with the male contact 5 is reduced by pressing the inner contact portion 6 due to the deformation of the stress deformable portion 7.

このとき、仮に、応力変形部７においてバネ材料９に導電材料８を張り合わせると、導電材料８の特性が全体のバネ性に影響してバネ材料９単独でのバネ性より劣ってしまう。その点、本発明の電気コンタクト１では、応力変形部７がバネ材料９からなる単一層構造であるため、応力変形部７はバネ材料９が有するバネ性を損なうことなく十分に発揮できる。   At this time, if the conductive material 8 is bonded to the spring material 9 in the stress deforming portion 7, the characteristics of the conductive material 8 influences the overall spring property and is inferior to the spring property of the spring material 9 alone. In that respect, in the electrical contact 1 of the present invention, since the stress deforming portion 7 has a single layer structure made of the spring material 9, the stress deforming portion 7 can sufficiently exhibit without losing the spring property of the spring material 9.

また、従来のように電気コンタクト全体を導電材料である銅で形成した場合、銅は応力緩和が起こりやすく、応力変形部７におけるバネ性が時間経過（挿抜回数）に伴い低下してしまう。その点、本発明の電気コンタクト１では、応力変形部７にバネ材料９が使用されているため、応力緩和が起きないので、耐久性が向上する。   In addition, when the entire electrical contact is formed of copper, which is a conductive material, as in the conventional case, stress is easily relaxed in copper, and the spring property at the stress deformed portion 7 is lowered with time (number of insertions / removals). In that respect, in the electrical contact 1 of the present invention, since the spring material 9 is used for the stress deformed portion 7, stress relaxation does not occur, and thus durability is improved.

本発明の電気コンタクト１は、ブレード１５の１枚ごとの接触抵抗が低減するので、従来のようにブレードの枚数を増加させなくとも全体の抵抗を小さくすることができる。よって、ブレードの増加による径の拡大がなく、小さい電気コンタクト１で大電流を流すことができる。   Since the electrical contact 1 of the present invention reduces the contact resistance of each blade 15, the overall resistance can be reduced without increasing the number of blades as in the prior art. Therefore, there is no enlargement of the diameter due to an increase in blades, and a large current can be passed with the small electrical contact 1.
