Description

本発明は、接触端子に関する。   The present invention relates to a contact terminal.

基板に実装されるとともに、その基板に対向配置された他の部材と圧接し、基板と他の部材とを電気的に接続する導電性の圧接コネクタが開示されている（例えば、特許文献１参照）。特許文献１に開示された圧接コネクタは、基板に接続された下側平板部の端部からそれぞれ延設し、他の部材に接触する上側平板部を中心として同一方向に巻回する第１ばね部及び第２ばね部を備えている。第１ばね部及び第２ばね部の弾性力により、上側平板部は他の部材に圧接し、基板と他の部材とが電気的に接続される。   There is disclosed a conductive pressure contact connector that is mounted on a substrate, press-contacts with another member disposed opposite to the substrate, and electrically connects the substrate and the other member (see, for example, Patent Document 1). ). The press contact connector disclosed in Patent Document 1 is a first spring that extends from an end of a lower flat plate portion connected to a substrate and winds in the same direction around an upper flat plate portion that contacts another member. And a second spring part. Due to the elastic force of the first spring portion and the second spring portion, the upper flat plate portion is pressed against another member, and the substrate and the other member are electrically connected.

以下、本発明の実施の形態について、図面を参照して詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

実施の形態１．
まず、本発明の実施の形態１について説明する。 Embodiment 1 FIG.
First, the first embodiment of the present invention will be described.

本実施の形態に係る接触端子は、基板上の占有面積が小さく（例えば３．０ｍｍ×３．０ｍｍ）、スマートフォン等の小型の電子機器に内蔵される基板にも実装可能な金属（例えばリン青銅）製の端子である。図１（Ａ）に示すように、接触端子１Ａは、基板２上に実装される。本実施の形態では、基板２の実装面をＸＹ平面に平行な面とし、基板２の実装面の法線方向をＺ軸方向とする。   The contact terminal according to the present embodiment has a small occupied area on the substrate (for example, 3.0 mm × 3.0 mm) and can be mounted on a substrate incorporated in a small electronic device such as a smartphone (for example, phosphor bronze). ) Made of terminal. As shown in FIG. 1A, the contact terminal 1 </ b> A is mounted on the substrate 2. In the present embodiment, the mounting surface of the substrate 2 is a surface parallel to the XY plane, and the normal direction of the mounting surface of the substrate 2 is the Z-axis direction.

図１（Ａ）及び図１（Ｂ）に示すように、接触端子１Ａは、天板部１０と、第１のばね部１１と、第２のばね部１２と、を備える。天板部１０は、第１のばね部１１及び第２のばね部１２を介して基板２に接続されている。第１のばね部１１及び第２のばね部１２は、Ｚ軸方向に弾性力を有する弾性部材である。天板部１０は、第１のばね部１１及び第２のばね部１２の両方に連結され、両者に支持されている。このため、接触端子１Ａは、弾性方向（Ｚ軸方向）以外の方向から加えられる外力に対して強靱であり、その外力により変形又は破損し難くなっている。   As shown in FIGS. 1A and 1B, the contact terminal 1 </ b> A includes a top plate portion 10, a first spring portion 11, and a second spring portion 12. The top plate portion 10 is connected to the substrate 2 via the first spring portion 11 and the second spring portion 12. The first spring part 11 and the second spring part 12 are elastic members having an elastic force in the Z-axis direction. The top plate part 10 is connected to both the first spring part 11 and the second spring part 12 and supported by both. For this reason, the contact terminal 1A is strong against an external force applied from a direction other than the elastic direction (Z-axis direction), and is not easily deformed or damaged by the external force.

また、上記特許文献１に記載の圧接コネクタのように、Ｚ軸方向に伸縮するらせん状（言い換えればスパイラル）ばねは、その構造上、一般的に、伸縮方向に重なった部分がないことが設計上の制約となるので、限られた面積にばねを収める場合、ばね長（らせんに沿ったばねの長さ）が制限される。しかしながら、第１のばね部１１及び第２のばね部１２は、図１（Ａ）及び図１（Ｂ）に示すように、Ｚ軸方向に折り返された部分に弾力を持つ構造となっているので、Ｚ軸方向に重なった部分を許容し、事実上のばね長の制限をなくすことができる。よって、接触端子１Ａの設計の自由度が向上し、所望のばね長、変位量、弾性力を有する接触端子１Ａを得ることができる。   In addition, like the pressure contact connector described in Patent Document 1, a helical spring (in other words, a spiral) that expands and contracts in the Z-axis direction is generally designed so that there is no overlapping portion in the expansion and contraction direction due to its structure. Due to the above limitation, when the spring is accommodated in a limited area, the spring length (the length of the spring along the spiral) is limited. However, as shown in FIGS. 1A and 1B, the first spring portion 11 and the second spring portion 12 have a structure having elasticity in a portion folded in the Z-axis direction. Therefore, it is possible to allow a portion overlapping in the Z-axis direction, and to eliminate the practical limitation on the spring length. Therefore, the degree of freedom in designing the contact terminal 1A is improved, and the contact terminal 1A having a desired spring length, displacement, and elastic force can be obtained.

図２（Ａ）及び図２（Ｂ）に示すように、接触端子１Ａは、基板２と、基板２に対向配置される基板３との間に配置されている。接触端子１Ａは、第１のばね部１１及び第２のばね部１２の弾性力で、天板部１０に当接する基板３と圧接する。この接触端子１Ａにより、基板２と基板３とが電気的に接続される。   As shown in FIGS. 2A and 2B, the contact terminal 1 </ b> A is disposed between the substrate 2 and the substrate 3 disposed to face the substrate 2. The contact terminal 1 </ b> A is in pressure contact with the substrate 3 that contacts the top plate portion 10 by the elastic force of the first spring portion 11 and the second spring portion 12. The substrate 2 and the substrate 3 are electrically connected by the contact terminal 1A.

図１に示す接触端子１Ａは、部品点数を削減すべく、図３に示す１枚の金属平板１Ａ（例えば板厚０．０７ｍｍ）から形成される。図３に示すように、この金属平板１Ａは、天板部１０となる矩形状の金属板１０を中心に構成されている。さらに、この金属平板１Ａでは、金属板１０と連結され、互いに反対側に延びる細長状の一対の金属板１１，１２が設けられている。すなわち、金属板１１，１２は、金属板１０を挟むように配置されている。この一対の金属板１１，１２が、第１のばね部１１及び第２のばね部１２となる。   The contact terminal 1A shown in FIG. 1 is formed from one metal flat plate 1A (for example, plate thickness 0.07 mm) shown in FIG. 3 in order to reduce the number of parts. As shown in FIG. 3, the metal flat plate 1 </ b> A is configured around a rectangular metal plate 10 that becomes the top plate portion 10. Further, the metal flat plate 1A is provided with a pair of elongated metal plates 11 and 12 that are connected to the metal plate 10 and extend to opposite sides. That is, the metal plates 11 and 12 are disposed so as to sandwich the metal plate 10. The pair of metal plates 11 and 12 become the first spring portion 11 and the second spring portion 12.

言い換えると、第１のばね部１１の一端は、天板部１０の外縁と連結している。第２のばね部１２の一端は、天板部１０の中心Ｏに対し、第１のばね部１１の一端が連結する位置と点対称な位置で天板部１０の外縁と連結している。   In other words, one end of the first spring portion 11 is connected to the outer edge of the top plate portion 10. One end of the second spring portion 12 is connected to the outer edge of the top plate portion 10 at a position that is point-symmetric with respect to the center O of the top plate portion 10 where one end of the first spring portion 11 is connected.

金属平板１Ａは、図３に示す状態から、金属板１１及び金属板１２がプレス成形機でそれぞれ折り曲げられた後、キャリア（不図示）から切り離されて、図１（Ａ）及び図１（Ｂ）に示す接触端子１Ａとなり、基板２に実装される。   The metal flat plate 1A is separated from the carrier (not shown) after the metal plate 11 and the metal plate 12 are bent by a press molding machine from the state shown in FIG. The contact terminals 1A shown in FIG.

図１（Ａ）及び図１（Ｂ）に示すように、天板部１０は、接触端子１Ａの＋Ｚ側の端部に位置する矩形状の金属板である（図４（Ａ）参照）。天板部１０の中心Ｏには、球面状に突出した接点部１０Ａが設けられており、図２に示すように、接点部１０Ａが基板３と接触する。   As shown in FIGS. 1A and 1B, the top plate portion 10 is a rectangular metal plate located at the end of the contact terminal 1A on the + Z side (see FIG. 4A). A contact portion 10A protruding in a spherical shape is provided at the center O of the top plate portion 10, and the contact portion 10A is in contact with the substrate 3 as shown in FIG.

第１のばね部１１では、図１〜図３に示すように、天板部１０の外縁と連結する第１の連結部２０Ａが一端に設けられている。第１の連結部２０Ａは、天板部１０に対して基板２に向かって折り曲げられている。一方で、第１のばね部１１の他端には、基板２と接続する第１の基板接続部２１Ａが設けられている。第１の基板接続部２１Ａは、基板２に対向する部分を有している。第１の基板接続部２１Ａは、はんだ付けにより基板２に接続される。   In the 1st spring part 11, as shown in FIGS. 1-3, the 1st connection part 20A connected with the outer edge of the top-plate part 10 is provided in the end. The first connecting portion 20 </ b> A is bent toward the substrate 2 with respect to the top plate portion 10. On the other hand, at the other end of the first spring portion 11, a first substrate connection portion 21 </ b> A that connects to the substrate 2 is provided. The first substrate connecting portion 21 </ b> A has a portion facing the substrate 2. The first board connecting portion 21A is connected to the board 2 by soldering.

第１のばね部１１では、第１の連結部２０Ａと第１の基板接続部２１Ａとの間に第１の中間部２２Ａが設けられている。第１の中間部２２Ａは、天板部１０に平行な面内方向に折れ曲がった第１の折曲部２３Ａと、その面内方向に延びる第１の延設部２４Ａと、天板部１０から基板２に向かって天板部１０の法線方向（−Ｚ方向）に折り返された第１の折返部２５Ａとを有している。ここで、面内方向とは、２次元平面内の任意の方向をいう。天板部１０は、ＸＹ平面に平行であるため、ＸＹ平面内の任意のベクトルが指す方向が、天板部１０に平行な面内方向となる。ＸＹ平面の面内方向をＺ軸に直交する方向と言い換えることもできる。   In the first spring portion 11, a first intermediate portion 22A is provided between the first connecting portion 20A and the first substrate connecting portion 21A. The first intermediate portion 22A includes a first bent portion 23A bent in an in-plane direction parallel to the top plate portion 10, a first extending portion 24A extending in the in-plane direction, and the top plate portion 10. The first folded portion 25 </ b> A is folded back in the normal direction (−Z direction) of the top plate portion 10 toward the substrate 2. Here, the in-plane direction means an arbitrary direction in the two-dimensional plane. Since the top panel 10 is parallel to the XY plane, the direction indicated by an arbitrary vector in the XY plane is an in-plane direction parallel to the top panel 10. The in-plane direction of the XY plane can be rephrased as a direction orthogonal to the Z axis.

A portion overlapping in the Z-axis direction is formed in the first spring portion 11 by the first folded portion 25A.

第１のばね部１１は、弾性変形可能に構成されている。第１のばね部１１では、第１の中間部２２Ａが弾性変形する。第１の中間部２２Ａは、第１の折返部２５Ａが変形したり（図６（Ａ）参照）、第１の延設部２４Ａがねじれたりすることにより、Ｚ軸方向に伸縮する。   The first spring portion 11 is configured to be elastically deformable. In the first spring portion 11, the first intermediate portion 22A is elastically deformed. The first intermediate portion 22A expands and contracts in the Z-axis direction when the first folded portion 25A is deformed (see FIG. 6A) or the first extending portion 24A is twisted.

一方、図１（Ａ）及び図１（Ｂ）に示すように、第２のばね部１２には、天板部１０の外縁と連結する第２の連結部２０Ｂが一端に設けられている。第２の連結部２０Ｂは、基板２に向かって折り曲げられている。一方で、第２のばね部１２の他端には、基板２と接続する第２の基板接続部２１Ｂが設けられている。第２の基板接続部２１Ｂは、基板２に対向する部分を有している。第２の基板接続部２１Ｂは、はんだ付けにより基板２に接続される。   On the other hand, as shown in FIGS. 1 (A) and 1 (B), the second spring portion 12 is provided with a second connecting portion 20B connected to the outer edge of the top plate portion 10 at one end.

図３に示すように、第２の中間部２２Ｂは、第２の連結部２０Ｂから、第２の折曲部２３Ｂ、第２の延設部２４Ｂ、第２の折曲部２３Ｂ、第２の折返部２５Ｂ、第２の折曲部２３Ｂ、第２の延設部２４Ｂ、第２の折曲部２３Ｂ、第２の折返部２５Ｂ、第２の折曲部２３Ｂの順に連結されて、最終的に第２の基板接続部２１Ｂに連結されている。第２の折返部２５Ｂにより、第２のばね部１２には、Ｚ軸方向に重なった部分が形成される。   As shown in FIG. 3, the second intermediate portion 22B includes a second bent portion 23B, a second extending portion 24B, a second bent portion 23B, and a second bent portion from the second connecting portion 20B. The folded portion 25B, the second folded portion 23B, the second extending portion 24B, the second folded portion 23B, the second folded portion 25B, and the second folded portion 23B are connected in this order, and finally Are connected to the second board connecting portion 21B. A portion overlapping in the Z-axis direction is formed in the second spring portion 12 by the second folded portion 25B.

第２のばね部１２は、弾性変形可能に構成されている。第２のばね部１２では、第２の中間部２２Ｂが弾性変形する。第２の中間部２２Ｂは、第２の折返部２５Ｂが変形したり（図６（Ａ）参照）、第２の延設部２４Ｂがねじれたりすることにより、Ｚ軸方向に伸縮する。   The second spring portion 12 is configured to be elastically deformable. In the second spring portion 12, the second intermediate portion 22B is elastically deformed. The second intermediate portion 22B expands and contracts in the Z-axis direction when the second folded portion 25B is deformed (see FIG. 6A) or the second extending portion 24B is twisted.

図４（Ｂ）に示すように、第１のばね部１１及び第２のばね部１２は、Ｚ軸方向から見た場合に、互いに重ならないように配置されている。第１のばね部１１及び第２のばね部１２は、図６（Ａ）に示すように、第１の折返部２５Ａ及び第２の折返部２５Ｂが変形するなどして、Ｚ軸方向に弾性変形するので、例えば、Ｚ軸方向に凸となるらせん状にばね部を形成した場合にくらべ、ＸＹ平面の面内方向の変形量が小さくなる。このため、第１のばね部１１と第２のばね部１２とのＸＹ平面における位置を近接させることができるので、接触端子１Ａ全体を小型化することができる。   As shown in FIG. 4B, the first spring portion 11 and the second spring portion 12 are arranged so as not to overlap each other when viewed from the Z-axis direction. As shown in FIG. 6A, the first spring portion 11 and the second spring portion 12 are elastic in the Z-axis direction, for example, when the first folding portion 25A and the second folding portion 25B are deformed. For example, the amount of deformation in the in-plane direction of the XY plane is smaller than when the spring portion is formed in a spiral shape that is convex in the Z-axis direction. For this reason, since the position in the XY plane of the 1st spring part 11 and the 2nd spring part 12 can be brought close, the contact terminal 1A whole can be reduced in size.

また、図４（Ｂ）に示すように、基板２から見たときに、第１のばね部１１は、凹状に形成された部分を有しており、第２のばね部１２の少なくとも一部（第２の延設部２４Ｂ）が、第１のばね部１１が成す凹状の内側領域に内包されるように配置されている。これにより、接触端子１Ａの基板２への実装面積を小さくして、その小型化を図ることができる。   As shown in FIG. 4B, when viewed from the substrate 2, the first spring portion 11 has a concave portion, and at least a part of the second spring portion 12. The (second extending portion 24 </ b> B) is disposed so as to be included in the concave inner region formed by the first spring portion 11. Thereby, the mounting area to the board | substrate 2 of the contact terminal 1A can be made small, and the size reduction can be achieved.

また、図４（Ｂ）に示すように、第１の基板接続部２１Ａ及び第２の基板接続部２１Ｂは、基板２から見たときに天板部１０の中心Ｏを基準として点対称に配置されている。このようにすれば、接触端子１Ａをバランス良く安定して保持することができる。図５に示すように、第１の基板接続部２１Ａ及び第２の基板接続部２１Ｂは、天板部１０の対向する縁部から−Ｚ方向に離れた位置にそれぞれ配置されている。   Further, as shown in FIG. 4B, the first substrate connecting portion 21A and the second substrate connecting portion 21B are arranged symmetrically with respect to the center O of the top plate portion 10 when viewed from the substrate 2. Has been. In this way, the contact terminal 1A can be stably held with good balance. As shown in FIG. 5, the first substrate connecting portion 21 </ b> A and the second substrate connecting portion 21 </ b> B are arranged at positions away from the opposing edge portions of the top plate portion 10 in the −Z direction.

次に、基板２と基板３との間に配置された接触端子１Ａの動作について説明する。   Next, the operation of the contact terminal 1A arranged between the substrate 2 and the substrate 3 will be described.

接触端子１Ａは、図２（Ａ）及び図２（Ｂ）に示すように、第１のばね部１１及び第２のばね部１２に余裕がある状態で、基板２と基板３とを電気的に接続する。接触端子１Ａは、信号伝送用にも、接地用にも用いられる。   As shown in FIG. 2A and FIG. 2B, the contact terminal 1A electrically connects the substrate 2 and the substrate 3 with the first spring portion 11 and the second spring portion 12 having a margin. Connect to. The contact terminal 1A is used for both signal transmission and grounding.

基板２と基板３との間隔が変動すると、図６（Ｂ）に示すように、接触端子１Ａは、その変動に応じて伸縮する。この場合でも、第１のばね部１１及び第２のばね部１２は、Ｚ軸方向に変形するだけであり、互いに干渉することはない。   When the distance between the substrate 2 and the substrate 3 varies, the contact terminal 1A expands and contracts in accordance with the variation, as shown in FIG. 6B. Even in this case, the first spring portion 11 and the second spring portion 12 only deform in the Z-axis direction and do not interfere with each other.

実施の形態２．
次に、本発明の実施の形態２について説明する。 Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described.

本実施の形態２に係る接触端子１Ｂは、図７（Ａ）及び図７（Ｂ）に示すように、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂをさらに備える点が、上記実施の形態１に係る接触端子１Ａと異なっている。ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、第１のばね部１１及び第２のばね部１２を、ＸＹ平面における四方から取り囲んでいる。ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、接触端子１Ｂの実装中に、作業者の手が第１のばね部１１及び第２のばね部１２に接触して、変形するのを防止する。また、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、第１のばね部１１及び第２のばね部１２がＸＹ平面の面内方向に過度に歪むのを規制する。   As shown in FIGS. 7A and 7B, the contact terminal 1B according to the second embodiment is further provided with guards 30A, 31A, 30B, and 31B, according to the first embodiment. Different from the terminal 1A. The guards 30A, 31A, 30B, 31B surround the first spring part 11 and the second spring part 12 from four directions in the XY plane. The guards 30A, 31A, 30B, and 31B prevent the operator's hand from coming into contact with the first spring portion 11 and the second spring portion 12 and deforming during mounting of the contact terminal 1B. Further, the guards 30A, 31A, 30B, 31B restrict the first spring portion 11 and the second spring portion 12 from being excessively distorted in the in-plane direction of the XY plane.

図８に示すように、ガード３０Ａ，３０Ｂは、天板部１０に連結されており、ガード３１Ａは、ガード３０Ａに連結されており、ガード３１Ｂは、ガード３０Ｂに連結されている。ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、天板部１０と一体化した金属板１１，１２で構成されている。   As shown in FIG. 8, the guards 30A and 30B are connected to the top plate 10, the guard 31A is connected to the guard 30A, and the guard 31B is connected to the guard 30B. The guards 30 </ b> A, 31 </ b> A, 30 </ b> B, and 31 </ b> B are configured by metal plates 11 and 12 that are integrated with the top plate portion 10.

ガード３０Ａ，３０Ｂは、天板部１０に対して直角に折り曲げられ、ガード３１Ａ，３１Ｂは、ガード３０Ａ，３０Ｂに対して直角に折り曲げられて、配置される。図９（Ａ）及び図９（Ｂ）に示すように、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、第１のばね部１１及び第２のばね部１２を囲むように配置され、第１のばね部１１及び第２のばね部１２を保護する保護部となっている。   The guards 30A and 30B are bent at a right angle with respect to the top plate 10, and the guards 31A and 31B are bent at a right angle with respect to the guards 30A and 30B. As shown in FIGS. 9A and 9B, the guards 30A, 31A, 30B, and 31B are arranged so as to surround the first spring portion 11 and the second spring portion 12, and the first spring. It is a protective part that protects the part 11 and the second spring part 12.

基板２と基板３との間隔に応じて第１のばね部１１及び第２のばね部１２は、上述のように、Ｚ軸方向に伸縮する。第１のばね部１１及び第２のばね部１２が縮み量に余裕がある状態では、図１０（Ａ）に示すように、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、基板２から浮いている。これに対して、図１０（Ｂ）に示すように、第１のばね部１１及び第２のばね部１２のＺ軸方向の変位量が許容値を超えようとする場合に、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、基板２と当接して第１のばね部１１及び第２のばね部１２がこれ以上縮まないように保護する。このようにすれば、第１のばね部１１及び第２のばね部１２が過度に変形するのを防止することができる。   As described above, the first spring portion 11 and the second spring portion 12 expand and contract in the Z-axis direction according to the distance between the substrate 2 and the substrate 3. In a state in which the first spring portion 11 and the second spring portion 12 have a sufficient amount of contraction, the guards 30A, 31A, 30B, and 31B are floating from the substrate 2 as shown in FIG. On the other hand, as shown in FIG. 10B, when the displacement amount in the Z-axis direction of the first spring portion 11 and the second spring portion 12 is about to exceed the allowable value, the guards 30A and 31A. , 30B, 31B abut against the substrate 2 to protect the first spring portion 11 and the second spring portion 12 from further contraction. If it does in this way, it can prevent that the 1st spring part 11 and the 2nd spring part 12 deform | transform excessively.

また、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂは、Ｚ軸方向の長さが同じである。このため、ガード３０Ａ，３１Ａ，３０Ｂ，３１Ｂを基板２に当接させながら、接触端子１Ｂを基板２に実装するようにすれば、天板部１０を基板２に対して平行に設置することができる。   Further, the guards 30A, 31A, 30B, 31B have the same length in the Z-axis direction. For this reason, if the contact terminals 1B are mounted on the substrate 2 while the guards 30A, 31A, 30B, 31B are in contact with the substrate 2, the top plate 10 can be installed parallel to the substrate 2. it can.

以上詳細に説明したように、上記各実施の形態によれば、第１のばね部１１及び第２のばね部１２が天板部１０と一体化している。このため、弾性方向以外の方向の外力が加わったとしても、第１のばね部１１及び第２のばね部１２により天板部１０を強固に支持することができるので、弾性方向以外の方向の外力に対して変形又は破損しにくくすることができる。   As described above in detail, according to the above embodiments, the first spring portion 11 and the second spring portion 12 are integrated with the top plate portion 10. For this reason, even if an external force in a direction other than the elastic direction is applied, the top plate portion 10 can be firmly supported by the first spring portion 11 and the second spring portion 12, so It can be made difficult to deform or break against external force.

すなわち、本実施の形態では、天板部１０が第１のばね部１１と第２のばね部１２との両方に接続されているので、天板部１０を基板２上で安定して保持することができる。   That is, in the present embodiment, the top plate portion 10 is connected to both the first spring portion 11 and the second spring portion 12, so that the top plate portion 10 is stably held on the substrate 2. be able to.

また、上記各実施の形態に係る接触端子１Ａ，１Ｂでは、第１のばね部１１及び第２のばね部１２を、例えばらせん状に形成する場合とは異なり、上述のように、Ｚ軸方向から見て重なる部分を有しないように設計する必要があるという制約を不要とすることができる。このため、らせん状に形成した場合にくらべ、第１のばね部１１及び第２のばね部１２のばね長をより長くすることができる。ばね長を長くすることができれば、ばね長を調整して、第１のばね部１１及び第２のばね部１２の接圧等を調整することも容易となる。すなわち、上記各実施の形態に係る接触端子１Ａ，１Ｂにおける設計の自由度を向上し、所望のばね長、変位量、弾性力を有する接触端子１Ａ，１Ｂを得ることができる。   Further, in the contact terminals 1A and 1B according to the above embodiments, unlike the case where the first spring portion 11 and the second spring portion 12 are formed in a spiral shape, for example, as described above, the Z-axis direction Therefore, it is possible to eliminate the restriction that it is necessary to design so as not to have overlapping portions. For this reason, compared with the case where it forms in a spiral shape, the spring length of the 1st spring part 11 and the 2nd spring part 12 can be made longer. If the spring length can be increased, it becomes easy to adjust the contact length of the first spring portion 11 and the second spring portion 12 by adjusting the spring length. That is, the design flexibility of the contact terminals 1A and 1B according to the above embodiments can be improved, and the contact terminals 1A and 1B having a desired spring length, displacement, and elastic force can be obtained.

また、第１のばね部１１及び第２のばね部１２を天板部１０と一体化することにより、基板２に接続する大きな底板を不要とすることができる。   Further, by integrating the first spring portion 11 and the second spring portion 12 with the top plate portion 10, a large bottom plate connected to the substrate 2 can be dispensed with.

また、上記各実施の形態によれば、天板部１０に第１のばね部１１及び第２のばね部１２が接続され、第１のばね部１１の端部に第１の基板接続部２１Ａが設けられ、第２のばね部１２の端部に第２の基板接続部２１Ｂが設けられ、それぞれの基板接続部が独立して形成される（図５参照）。すなわち、第１の基板接続部２１Ａ及び第２の基板接続部２１Ｂの位置は、図４（Ｂ）に示すように、天板部１０を中心に設計されるので、第１の基板接続部２１Ａから天板部１０までの高さと、第２の基板接続部２１Ｂから天板部１０までの高さとを精度良く揃えることができる。この結果、天板部１０を基板２の実装面と平行に配置し易くなる。   Further, according to each of the above embodiments, the first spring portion 11 and the second spring portion 12 are connected to the top plate portion 10, and the first board connecting portion 21 </ b> A is connected to the end portion of the first spring portion 11. Is provided, and the second substrate connecting portion 21B is provided at the end of the second spring portion 12, and each substrate connecting portion is formed independently (see FIG. 5). That is, the positions of the first substrate connecting portion 21A and the second substrate connecting portion 21B are designed around the top plate portion 10 as shown in FIG. 4B, and therefore the first substrate connecting portion 21A. To the top plate portion 10 and the height from the second board connecting portion 21B to the top plate portion 10 can be aligned with high accuracy. As a result, it becomes easy to arrange the top plate 10 parallel to the mounting surface of the substrate 2.

なお、上記実施の形態１では、第１の基板接続部２１Ａ及び第２の基板接続部２１Ｂの基板２に対向する部分において、金属板が天板部１０に向かって折り返された部分を有するものとしてもよい。なお、この折り返しの数は１回に限らず、複数回折り返すようにしてもよい。このようにすれば、第１の基板接続部２１Ａ及び第２の基板接続部２１Ｂにおいて、基板２と接触する部分の面積をより大きくすることができる。また、金属板をすぐ折り返すのではなく、基板２との接触する部分を広くとってから折り返すようにしてもよい。   In the first embodiment, the portion of the first substrate connecting portion 21A and the second substrate connecting portion 21B facing the substrate 2 has a portion where the metal plate is folded back toward the top plate portion 10. It is good. Note that the number of turns is not limited to one, and a plurality of turns may be folded back. If it does in this way, in the 1st substrate connection part 21A and the 2nd substrate connection part 21B, the area of the part which contacts substrate 2 can be enlarged more. In addition, the metal plate may not be folded immediately, but may be folded after widening a portion in contact with the substrate 2.

また、第１の基板接続部２１Ａ及び第２の基板接続部２１Ｂでは、基板２に対向する部分を、基板２から見たときに折り曲がったＬ字状としてもよい。これらは、Ｕ字状、四角形状など、他の折れ曲がった形状であってもよい。すなわち、折り曲げ数は複数回であってもよく、折り曲がる向きも任意である。折り曲げた回数及び方向が多ければ多いほど、接触端子１Ａを安定して保持することができる。   Further, in the first substrate connecting portion 21A and the second substrate connecting portion 21B, a portion facing the substrate 2 may be formed in an L shape that is bent when viewed from the substrate 2. These may be other bent shapes such as a U-shape and a quadrangular shape. That is, the number of bends may be multiple, and the direction of the bend is arbitrary. The more the number and direction of bending, the more stable the contact terminal 1A can be held.

また、上記各実施の形態では、図４（Ｂ）に示すように、第１のばね部１１及び第２のばね部１２は、基板２から見たときに、凹状となっており、互いの一部を凹状の内部領域に位置するように（互い違いに）配置されている。しかしながら、本発明はこれには限られない。第１のばね部１１と第２のばね部１２とを別々の領域に配置してもよい。第１のばね部１１及び第２のばね部１２のＸＹ平面と平行な面内方向における折れ曲がり方向は、両者が干渉しないのであれば、特に制限はない。すなわち、第１の折曲部２３Ａ及び第２の折曲部２３Ｂの数は幾つであってもよい。第１のばね部１１及び第２のばね部１２が、図１１（Ａ）に示すように、基板２から見たときに、第１のばね部１１及び第２のばね部１２は、Ｌ字状であってもよいし、図１１（Ｂ）に示すように、渦巻き状であってもよいし、図１１（Ｃ）に示すように、Ｓ字状であってもよい。   Moreover, in each said embodiment, as shown to FIG. 4 (B), when it sees from the board | substrate 2, the 1st spring part 11 and the 2nd spring part 12 become concave shape, and each other It arrange | positions so that a part may be located in a concave internal area | region (it staggered).
