Description
本発明は、圧接コネクタに関するものである。 The present invention relates to a pressure welding connector.
近年、電子機器の小型化の傾向が進んでおり、このような電子機器に内蔵される異なる基板同士を電気的に接続する方法として、圧接コネクタが用いられている。この圧接コネクタは、例えば、金属板を折り曲げることにより形成されており、一方の接続端子と他方の接続端子とを有しており、一方の接続端子と他方の接続端子との間は弾性を有しバネとして機能する。 In recent years, there has been a trend toward miniaturization of electronic devices, and a pressure welding connector is used as a method of electrically connecting different substrates built in such an electronic device. This pressure welding connector is formed, for example, by bending a metal plate, has one connection terminal and the other connection terminal, and has elasticity between one connection terminal and the other connection terminal. Functions as a spring.
圧接コネクタは、一方の基板の電極端子に圧接コネクタの一方の接続端子をハンダ等により電気的に接続し、圧接コネクタの他方の接続端子に他方の基板の電極端子を接触させる。これにより、一方の基板の電極端子と他方の基板の電極端子とを圧接コネクタを介し電気的に接続することができる。この際、圧接コネクタの他方の接続端子が他方の基板の電極端子により押され、圧接コネクタの一方の接続端子と他方の接続端子との間が縮むことによりバネの復元力が生じる。この復元力により、圧接コネクタの他方の接続端子が、他方の基板の電極端子を押すことにより、圧接コネクタの他方の接続端子と他方の基板の電極端子との接触を確実にすることができる。 In the pressure welding connector, one connection terminal of the pressure welding connector is electrically connected to the electrode terminal of one board by soldering or the like, and the electrode terminal of the other board is brought into contact with the other connection terminal of the pressure welding connector. As a result, the electrode terminals on one substrate and the electrode terminals on the other substrate can be electrically connected via the pressure welding connector. At this time, the other connection terminal of the pressure welding connector is pushed by the electrode terminal of the other substrate, and the distance between one connection terminal of the pressure welding connector and the other connection terminal is contracted, so that the restoring force of the spring is generated. Due to this restoring force, the other connection terminal of the pressure welding connector pushes the electrode terminal of the other substrate, so that the contact between the other connection terminal of the pressure welding connector and the electrode terminal of the other substrate can be ensured.
ところで、上記のような圧接コネクタは１〜２ｍｍ程度と小さいため、圧接コネクタの他方の接続端子が、他方の基板の電極端子により押されると、圧接コネクタの他方の接続端子とバネとの接続部分が撓む場合がある。このように、圧接コネクタにおいて、意に反した力が加わると、他方の接続端子とバネとの接続部分が撓む場合があり、この場合には他方の接続端子の位置が不安定となり、安定した電気的な接続が得られなくなる。 By the way, since the pressure welding connector as described above is as small as about 1 to 2 mm, when the other connection terminal of the pressure welding connector is pushed by the electrode terminal of the other substrate, the connection portion between the other connection terminal of the pressure welding connector and the spring. May bend. In this way, when an unexpected force is applied to the pressure welding connector, the connection portion between the other connection terminal and the spring may bend, and in this case, the position of the other connection terminal becomes unstable and stable. You will not be able to obtain the electrical connection you made.
このため、圧接コネクタの他方の接続端子とバネとの接続部分との間における撓みが少なく、他方の基板の電極端子との電気的な接続を確実に得ることのできる圧接コネクタが求められている。 For this reason, there is a demand for a pressure welding connector that has less bending between the other connection terminal of the pressure welding connector and the connection portion between the spring and can reliably obtain an electrical connection with the electrode terminal of the other substrate. ..
本実施の形態の一観点によれば、一方の側に形成された一方の接続端子部と、他方の側に形成された他方の接続端子部と、前記一方の接続端子部と前記他方の接続端子部との間に形成された弾性を有する螺旋形状の弾性部と、を有し、前記一方の接続端子部、前記他方の接続端子部及び前記弾性部は、導電性を有する材料により形成されており、前記弾性部には、前記他方の接続端子部が前記一方の接続端子部の側に押された際に、前記他方の接続端子部の裏面に当接する受け部が設けられていることを特徴とする。 According to one aspect of the present embodiment, one connection terminal portion formed on one side, the other connection terminal portion formed on the other side, and the connection between the one connection terminal portion and the other connection. It has an elastic spiral-shaped elastic portion formed between the terminal portion, and the one connection terminal portion, the other connection terminal portion, and the elastic portion are formed of a conductive material. The elastic portion is provided with a receiving portion that comes into contact with the back surface of the other connection terminal portion when the other connection terminal portion is pushed toward the one connection terminal portion. It is characterized by.
開示の圧接コネクタによれば、圧接コネクタの他方の接続端子とバネとの接続部分との間における撓みが少なく、他方の基板の電極端子との電気的な接続を確実に得ることができる。 According to the disclosed pressure welding connector, there is little deflection between the other connection terminal of the pressure welding connector and the connection portion between the spring, and an electrical connection with the electrode terminal of the other substrate can be reliably obtained.
実施するための形態について、以下に説明する。尚、同じ部材等については、同一の符号を付して説明を省略する。尚、本願においては、Ｘ１−Ｘ２方向、Ｙ１−Ｙ２方向、Ｚ１−Ｚ２方向を相互に直交する方向とする。また、Ｘ１−Ｘ２方向及びＹ１−Ｙ２方向を含む面をＸＹ面と記載し、Ｙ１−Ｙ２方向及びＺ１−Ｚ２方向を含む面をＹＺ面と記載し、Ｚ１−Ｚ２方向及びＸ１−Ｘ２方向を含む面をＺＸ面と記載する。 The embodiment for carrying out will be described below.

In the present application, the X1-X2 direction, the Y1-Y2 direction, and the Z1-Z2 direction are orthogonal to each other. Further, the surface including the X1-X2 direction and the Y1-Y2 direction is described as the XY surface, the surface including the Y1-Y2 direction and the Z1-Z2 direction is described as the YZ surface, and the Z1-Z2 direction and the X1-X2 direction are described as the YZ surface. The including surface is referred to as a ZX surface.
最初に、従来の圧接コネクタについて図１及び図２に基づきより詳細に説明する。この圧接コネクタは、図１及び図２に示されるように、一方の接続端子部９１０、他方の接続端子部９２０、一方の接続端子部９１０と他方の接続端子部９２０との間に設けられた第１のバネ部９３０とを有している。また、他方の接続端子部９２０の裏側には、平坦支持部９４０が設けられており、一方の接続端子部９１０と平坦支持部９４０との間には第２のバネ部９５０が設けられている。圧接コネクタの一方の接続端子部９１０は一方の基板の電極端子にハンダ等により接続されており、他方の基板の電極端子が、圧接コネクタの他方の接続端子部９２０に接触することにより、一方の基板の電極端子と他方の基板の電極端子とが電気的に接続される。 First, the conventional pressure welding connector will be described in more detail with reference to FIGS. 1 and 2. As shown in FIGS. 1 and 2, the pressure welding connector is provided between one connection terminal portion 910, the other connection terminal portion 920, one connection terminal portion 910, and the other connection terminal portion 920. It has a first spring portion 930. A flat support portion 940 is provided on the back side of the other connection terminal portion 920, and a second spring portion 950 is provided between the one connection terminal portion 910 and the flat support portion 940. .. One connection terminal portion 910 of the pressure welding connector is connected to the electrode terminal of one substrate by solder or the like, and the electrode terminal of the other substrate comes into contact with the other connection terminal portion 920 of the pressure welding connector, thereby causing one of them. The electrode terminals on the substrate and the electrode terminals on the other substrate are electrically connected.
従って、他方の接続端子部９２０には、凸状の接触部９２１が設けられている。この圧接コネクタは、金属板を打ち抜き加工した後、折り曲げることにより形成されており、他方の接続端子部９２０の接触部９２１は、金属板を裏から押し出すことにより形成されているため、他方の接続端子部９２０の接触部９２１の表面は曲面となっている。ところで、このような圧接コンタクトは、一方の接続端子部９１０の大きさが、約１．４ｍｍ×１．４ｍｍと極めて小さく、金属板の厚さも約０．１ｍｍと薄い。 Therefore, the other connection terminal portion 920 is provided with a convex contact portion 921. This pressure welding connector is formed by punching a metal plate and then bending it, and the contact portion 921 of the other connection terminal portion 920 is formed by extruding the metal plate from the back, so that the other connection is made. The surface of the contact portion 921 of the terminal portion 920 is a curved surface. By the way, in such a pressure contact, the size of one connection terminal portion 910 is extremely small, about 1.4 mm × 1.4 mm, and the thickness of the metal plate is also as thin as about 0.1 mm.
このため、他方の基板の電極端子と圧接コネクタの他方の接続端子部９２０とが接触する際等において、圧接コネクタの他方の接続端子部９２０に意に反した力が加わると、圧接コネクタの他方の接続端子部９２０と第１のバネ部９３０との接続部分で撓む場合がある。このように、圧接コネクタの他方の接続端子部９２０と第１のバネ部９３０との接続部分が撓むと、圧接コネクタの他方の接続端子部９２０の位置が不安定となり、圧接コネクタの他方の接続端子部９２０と他方の基板の電極端子との間において、安定した電気的な接続が得られない。 Therefore, when an unexpected force is applied to the other connection terminal portion 920 of the pressure welding connector when the electrode terminal of the other substrate and the other connection terminal portion 920 of the pressure welding connector come into contact with each other, the other of the pressure welding connector The connection portion between the connection terminal portion 920 and the first spring portion 930 may be bent. When the connection portion between the other connection terminal portion 920 of the pressure welding connector and the first spring portion 930 is bent in this way, the position of the other connection terminal portion 920 of the pressure welding connector becomes unstable, and the other connection of the pressure welding connector is made. A stable electrical connection cannot be obtained between the terminal portion 920 and the electrode terminal of the other substrate.
このことは、特に圧接コネクタの高さの低い低背タイプの場合に特に顕著となる。具体的には、図３（ａ）に示される圧接コネクタの他方の接続端子部９２０を他方の基板の電極端子が形成されている部分を接触させて押した場合、図３（ｂ）に示されるように第２のバネ部９５０の一部が一方の接続端子部９１０に接触する。このため、これ以上奥には押し込むことができず、通常と同じストローク量を得ようとすると、低背化に対応することができない。これを解決する方法としては、図３（ｃ）に示されるように、第２のバネ部９５０ａの幅を一部細くして、第２のバネ部９５０ａと一方の接続端子部９１０との接触を防ぐ方法が考えられる。この場合、第２のバネ部９５０ａの幅を細くした分、奥に押し込むことができるため、低背化に対応することができる。 This is particularly remarkable in the case of a low profile type in which the height of the pressure welding connector is low. Specifically, when the other connection terminal portion 920 of the pressure welding connector shown in FIG. 3A is pressed by contacting the portion where the electrode terminal of the other substrate is formed, it is shown in FIG. 3B. A part of the second spring portion 950 comes into contact with one of the connection terminal portions 910. For this reason, it cannot be pushed further inward, and if the same stroke amount as usual is to be obtained, it is not possible to cope with the reduction in height. As a method for solving this, as shown in FIG. 3C, the width of the second spring portion 950a is partially narrowed, and the contact between the second spring portion 950a and one connection terminal portion 910 is performed. Can be considered as a way to prevent. In this case, since the width of the second spring portion 950a is narrowed and can be pushed into the back, it is possible to cope with the reduction in height.
しかしながら、第２のバネ部９５０ａの幅を細くすると、その分強度が下がり、第２のバネ部９５０ａの幅の細い部分等において曲がりやすくなり、他方の接続端子部９２０の位置が更に不安定となり、第２のバネ部９５０ａにおける復元力も低下する。このため、圧接コネクタの他方の接続端子部９２０と他方の基板の電極端子との間において、安定した電気的な接続を得ることが困難になる。 However, if the width of the second spring portion 950a is narrowed, the strength is lowered by that amount, and it becomes easy to bend in the narrow portion of the second spring portion 950a, and the position of the other connection terminal portion 920 becomes more unstable. , The restoring force at the second spring portion 950a also decreases. Therefore, it becomes difficult to obtain a stable electrical connection between the other connection terminal portion 920 of the pressure welding connector and the electrode terminal of the other substrate.

It is formed. As shown in the drawing, one connection terminal portion 10 is formed to be substantially flat so that the surface connected to the electrode terminal of one substrate (not shown) is parallel to the XY surface.
第１のバネ部３０は、一方の接続端子部１０より他方の接続端子部２０まで矩形の螺旋形状により形成されている。具体的には、第１のバネ部３０には、ＸＹ面と平行な一方の接続端子部１０に対し、下側折り曲げ部１１においてＺ１方向に略直角に折り曲げることにより、ＺＸ面に平行な第１の側面部３１が形成されている。また、第１の側面部３１に対し第１の折り曲げ部３２においてＹ２方向に略直角に折り曲げることにより第２の側面部３３が形成されている。また、第２の側面部３３に対し第２の折り曲げ部３４においてＸ２方向に略直角に折り曲げることにより第３の側面部３５が形成されている。また、第３の側面部３５に対し第３の折り曲げ部３６においてＹ１方向に略直角に折り曲げることにより第４の側面部３７が形成されている。 The first spring portion 30 is formed in a rectangular spiral shape from one connection terminal portion 10 to the other connection terminal portion 20. Specifically, the first spring portion 30 is bent at a lower bending portion 11 at a substantially right angle in the Z1 direction with respect to one connection terminal portion 10 parallel to the XY plane, so that the first spring portion 30 is parallel to the ZX plane. The side surface portion 31 of 1 is formed. Further, the second side surface portion 33 is formed by bending the first side surface portion 31 at a substantially right angle in the Y2 direction at the first bent portion 32. Further, the third side surface portion 35 is formed by bending the second side surface portion 33 at a substantially right angle in the X2 direction at the second bent portion 34. Further, the fourth side surface portion 37 is formed by bending the third side surface portion 35 at a substantially right angle in the Y1 direction at the third bent portion 36.
従って、第１のバネ部３０は、第１の側面部３１、第１の折り曲げ部３２、第２の側面部３３、第２の折り曲げ部３４、第３の側面部３５、第３の折り曲げ部３６、第４の側面部３７により形成されており、Ｚ１−Ｚ２方向に伸縮するバネ性を有している。尚、第１のバネ部３０における第１の側面部３１、第２の側面部３３、第３の側面部３５、第４の側面部３７の金属板の面は、Ｚ１−Ｚ２方向と略平行である。 Therefore, the first spring portion 30 includes a first side surface portion 31, a first bent portion 32, a second side surface portion 33, a second bent portion 34, a third side surface portion 35, and a third bent portion. It is formed by 36 and a fourth side surface portion 37, and has a spring property that expands and contracts in the Z1-Z2 direction. The surfaces of the metal plates of the first side surface portion 31, the second side surface portion 33, the third side surface portion 35, and the fourth side surface portion 37 of the first spring portion 30 are substantially parallel to the Z1-Z2 direction. Is.
他方の接続端子部２０は、第４の側面部３７に対し上部折り曲げ部３８においてＸ１方向に略直角に折り曲げることにより形成されており、全体が、ＸＹ面に略平行に形成されている。このため、第１のバネ部３０は、一方の接続端子部１０と他方の接続端子部２０との間が伸縮する方向においてバネ性を有している。本願においては、第１のバネ部３０を第１の弾性部と記載する場合がある。 The other connection terminal portion 20 is formed by bending the upper bent portion 38 with respect to the fourth side surface portion 37 at a substantially right angle in the X1 direction, and is formed as a whole substantially parallel to the XY plane. Therefore, the first spring portion 30 has a spring property in a direction in which one connection terminal portion 10 and the other connection terminal portion 20 expand and contract. In the present application, the first spring portion 30 may be referred to as the first elastic portion.
本実施の形態においては、第１のバネ部３０の第３の側面部３５には、他方の接続端子部２０の側となるＺ１方向側に出っ張った第１の垂直支持部６１が形成されている。第１の垂直支持部６１は、他方の接続端子部２０が押された場合に、他方の接続端子部２０を支持する。よって、圧接コネクタの上面視では、第１の垂直支持部６１の一部は、他方の接続端子部２０により覆われており、打ち抜き加工により形成された第１の垂直支持部６１の金属板の板厚方向の面が、他方の接続端子部２０の裏面側と対向している。また、第１の垂直支持部６１が形成されている第３の側面部３５と上部折り曲げ部３８との間の第３の折り曲げ部３６等の幅は、第１のバネ部３０の他の部分、即ち、第１の側面部３１、第１の折り曲げ部３２、第２の側面部３３、第２の折り曲げ部３４、第３の側面部３５よりも細く形成されている。このように、第１のバネ部３０の第３の折り曲げ部３６等の幅を細くすることにより、低背化に対応している。 In the present embodiment, the third side surface portion 35 of the first spring portion 30 is formed with a first vertical support portion 61 protruding in the Z1 direction, which is the side of the other connection terminal portion 20. There is. The first vertical support portion 61 supports the other connection terminal portion 20 when the other connection terminal portion 20 is pushed. Therefore, in the top view of the pressure welding connector, a part of the first vertical support portion 61 is covered with the other connection terminal portion 20, and the metal plate of the first vertical support portion 61 formed by punching is formed. The surface in the plate thickness direction faces the back surface side of the other connection terminal portion 20. Further, the width of the third bent portion 36 or the like between the third side surface portion 35 on which the first vertical support portion 61 is formed and the upper bent portion 38 is the other portion of the first spring portion 30. That is, it is formed thinner than the first side surface portion 31, the first bent portion 32, the second side surface portion 33, the second bent portion 34, and the third side surface portion 35. In this way, by narrowing the width of the third bent portion 36 and the like of the first spring portion 30, it is possible to reduce the height.
他方の接続端子部２０は、不図示の他方の基板の電極端子と接触し電気的に接続されるものであり、円形の形状の一部となる平坦部２１と平坦部２１の周囲に設けられた第１の突起部２２、第２の突起部２３、第３の突起部２４を有している。平坦部２１は、一方の接続端子部１０と略平行となるように形成されている。また、第１の突起部２２の先端２２ａ、第２の突起部２３の先端２３ａ、第３の突起部２４の先端２４ａは尖っている。このように、第１の突起部２２の先端２２ａ、第２の突起部２３の先端２３ａ、第３の突起部２４の先端２４ａを尖らせることにより、先端２２ａ、２３ａ及び２４ａにより、他方の基板の電極端子がアルミニウム等により形成されている場合であっても、表面の酸化被膜を破ることができ、他方の基板の電極端子と電気的に接続することができる。 The other connection terminal portion 20 is electrically connected in contact with the electrode terminal of the other substrate (not shown), and is provided around the flat portion 21 and the flat portion 21 which are a part of the circular shape. It also has a first protrusion 22, a second protrusion 23, and a third protrusion 24. The flat portion 21 is formed so as to be substantially parallel to one of the connection terminal portions 10. Further, the tip 22a of the first protrusion 22, the tip 23a of the second protrusion 23, and the tip 24a of the third protrusion 24 are sharp. In this way, by sharpening the tip 22a of the first protrusion 22, the tip 23a of the second protrusion 23, and the tip 24a of the third protrusion 24, the other substrate is formed by the tips 22a, 23a, and 24a. Even when the electrode terminals of the above are made of aluminum or the like, the oxide film on the surface can be broken and the electrode terminals of the other substrate can be electrically connected.
また、図９及び図１０にも示されるように、第２のバネ部５０は、一方の接続端子部１０より平坦支持部４０まで、矩形の螺旋形状により形成されている。尚、図９は、図８（ｂ）において、一点鎖線８Ａ−８Ｂにおいて切断し、他方の接続端子部２０を取り除いた状態の上面図であり、図１０は、この状態の斜視図である。 Further, as shown in FIGS. 9 and 10, the second spring portion 50 is formed in a rectangular spiral shape from one connection terminal portion 10 to the flat support portion 40. 9 is a top view of FIG. 8B in a state where the alternate long and short dash line 8A-8B is cut and the other connection terminal portion 20 is removed, and FIG. 10 is a perspective view of this state.
具体的には、第２のバネ部５０には、ＸＹ面と平行な一方の接続端子部１０に対し、下側折り曲げ部１２においてＺ１方向に略直角に折り曲げることにより、ＺＸ面に平行な第１の側面部５１が形成されている。また、第１の側面部５１に対し第１の折り曲げ部５２においてＹ１方向に略直角に折り曲げることにより第２の側面部５３が形成されている。また、第２の側面部５３に対し第２の折り曲げ部５４においてＸ１方向に略直角に折り曲げることにより第３の側面部５５が形成されている。また、第３の側面部５５に対し第３の折り曲げ部５６においてＹ２方向に略直角に折り曲げることにより第４の側面部５７が形成されている。また、第４の側面部５７に対し第４の折り曲げ部５８においてＸ２方向に略直角に折り曲げることにより第５の側面部５９が形成されている。 Specifically, the second spring portion 50 is bent at a lower bending portion 12 at a substantially right angle in the Z1 direction with respect to one connection terminal portion 10 parallel to the XY plane, so that the second spring portion 50 is parallel to the ZX plane. The side surface portion 51 of 1 is formed. Further, the second side surface portion 53 is formed by bending the first side surface portion 51 at a substantially right angle in the Y1 direction at the first bent portion 52. Further, the third side surface portion 55 is formed by bending the second side surface portion 53 at a substantially right angle in the X1 direction at the second bent portion 54. Further, the fourth side surface portion 57 is formed by bending the third side surface portion 55 at a substantially right angle in the Y2 direction at the third bent portion 56. Further, the fifth side surface portion 59 is formed by bending the fourth side surface portion 57 at a substantially right angle in the X2 direction at the fourth bent portion 58.
従って、第２のバネ部５０は、第１の側面部５１、第１の折り曲げ部５２、第２の側面部５３、第２の折り曲げ部５４、第３の側面部５５、第３の折り曲げ部５６、第４の側面部５７、第４の折り曲げ部５８、第５の側面部５９により形成されており、Ｚ１−Ｚ２方向に伸縮するバネ性を有している。尚、第２のバネ部５０における第１の側面部５１、第２の側面部５３、第３の側面部５５、第４の側面部５７、第５の側面部５９の金属板の面は、Ｚ１−Ｚ２方向と平行となっている。 Therefore, the second spring portion 50 includes a first side surface portion 51, a first bent portion 52, a second side surface portion 53, a second bent portion 54, a third side surface portion 55, and a third bent portion. It is formed by 56, a fourth side surface portion 57, a fourth bent portion 58, and a fifth side surface portion 59, and has a spring property that expands and contracts in the Z1-Z2 direction. The surfaces of the metal plates of the first side surface portion 51, the second side surface portion 53, the third side surface portion 55, the fourth side surface portion 57, and the fifth side surface portion 59 of the second spring portion 50 are It is parallel to the Z1-Z2 direction.

（圧接コネクタによる接続）
次に、本実施の形態における圧接コネクタによる基板と基板の接続について、図１１から図１３に基づき説明する。尚、図１１から図１３における圧接コネクタの断面は、図６における一点鎖線６Ａ−６Ｂにおいて切断した断面に対応している。
(Connection by pressure welding connector)
Next, the connection between the substrates by the pressure welding connector in the present embodiment will be described with reference to FIGS. 11 to 13. The cross section of the pressure welding connector in FIGS. 11 to 13 corresponds to the cross section cut along the alternate long and short dash line 6A-6B in FIG.
最初に、図１１に示すように、一方の基板１１０の電極端子１１１に、本実施の形態における圧接コネクタの一方の接続端子部１０をハンダ等により接続する。 First, as shown in FIG. 11, one connection terminal portion 10 of the pressure welding connector according to the present embodiment is connected to the electrode terminal 111 of one substrate 110 by soldering or the like.
次に、図１２に示すように、本実施の形態における圧接コネクタの他方の接続端子部２０の第１の突起部２２等に他方の基板１２０の電極端子１２１を接触させて、他方の基板１２０を他方の接続端子部２０の側に押す。このように他方の基板１２０により他方の接続端子部２０が押されると、最初に、第１のバネ部３０が変形し、他方の接続端子部２０は一方の接続端子部１０の側に動き、他方の接続端子部２０と一方の接続端子部１０との間が狭くなる。これにより、他方の接続端子部２０は他方の接続端子部２０の裏面に設けられている平坦支持部４０と接触し、他方の接続端子部２０により平坦支持部４０は一方の接続端子部１０の側に押されるため、第２のバネ部５０も変形する。 Next, as shown in FIG. 12, the electrode terminal 121 of the other substrate 120 is brought into contact with the first protrusion 22 or the like of the other connection terminal portion 20 of the pressure welding connector in the present embodiment, and the other substrate 120 Is pushed toward the other connection terminal portion 20. When the other connection terminal portion 20 is pushed by the other substrate 120 in this way, the first spring portion 30 is first deformed, and the other connection terminal portion 20 moves to the side of the one connection terminal portion 10. The space between the other connection terminal portion 20 and the one connection terminal portion 10 becomes narrow. As a result, the other connection terminal portion 20 comes into contact with the flat support portion 40 provided on the back surface of the other connection terminal portion 20, and the other connection terminal portion 20 causes the flat support portion 40 to come into contact with the one connection terminal portion 10. Since it is pushed to the side, the second spring portion 50 is also deformed.
この際、他方の接続端子部２０の裏面２０ａと第１のバネ部３０の第３の側面部３５に設けられている第１の垂直支持部６１とが接触し、他方の接続端子部２０は第１のバネ部３０の第１の垂直支持部６１により支持される。このため、他方の接続端子部２０は、上部折り曲げ部３８において、これ以上曲がることはなく、他方の接続端子部２０の位置は動くことはない。尚、第１の垂直支持部６１は、打ち抜き加工により形成された第１の垂直支持部６１の金属板の板厚方向の面により、他方の接続端子部２０の裏面２０ａを支持している。 At this time, the back surface 20a of the other connection terminal portion 20 and the first vertical support portion 61 provided on the third side surface portion 35 of the first spring portion 30 come into contact with each other, and the other connection terminal portion 20 It is supported by the first vertical support portion 61 of the first spring portion 30. Therefore, the other connection terminal portion 20 does not bend any more at the upper bent portion 38, and the position of the other connection terminal portion 20 does not move. The first vertical support portion 61 supports the back surface 20a of the other connection terminal portion 20 by the surface of the metal plate of the first vertical support portion 61 formed by punching in the plate thickness direction.
また、平坦支持部４０の裏面４０ａと第２のバネ部５０の第４の側面部５７に設けられている第２の垂直支持部６２とが接触し、平坦支持部４０は第２のバネ部５０の第２の垂直支持部６２により支持される。平坦支持部４０は、上部折り曲げ部４１において、これ以上曲がることはなく、平坦支持部４０の位置は動くことはない。尚、第２の垂直支持部６２は、打ち抜き加工により形成された第２の垂直支持部６２の金属板の板厚方向の面により、平坦支持部４０の裏面４０ａを支持している。 Further, the back surface 40a of the flat support portion 40 and the second vertical support portion 62 provided on the fourth side surface portion 57 of the second spring portion 50 are in contact with each other, and the flat support portion 40 is the second spring portion. It is supported by a second vertical support portion 62 of 50. The flat support portion 40 does not bend any more at the upper bent portion 41, and the position of the flat support portion 40 does not move. The second vertical support portion 62 supports the back surface 40a of the flat support portion 40 by the surface of the metal plate of the second vertical support portion 62 formed by the punching process in the plate thickness direction.
このように、他方の接続端子部２０は、他方の基板１２０の電極端子１２１により押されても、他方の接続端子部２０の裏面２０ａにおいて、平坦支持部４０と第１のバネ部３０に設けられている第１の垂直支持部６１により支持されている。また、平坦支持部４０の裏面４０ａは、第２のバネ部５０に設けられている第２の垂直支持部６２により支持されている。従って、他方の接続端子部２０は、平坦支持部４０、第１のバネ部３０に設けられている第１の垂直支持部６１、第２のバネ部５０に設けられている第２の垂直支持部６２により支持されている。このため、他方の接続端子部２０が、他方の基板１２０の電極端子１２１により押されても、他方の接続端子部２０は、上部折り曲げ部３８において、曲がることはなく、他方の接続端子部２０の位置は安定しており、他方の基板１２０の電極端子１２１との電気的な接続を確実に得ることができる。 As described above, even if the other connection terminal portion 20 is pushed by the electrode terminal 121 of the other substrate 120, the other connection terminal portion 20 is provided on the flat support portion 40 and the first spring portion 30 on the back surface 20a of the other connection terminal portion 20. It is supported by the first vertical support portion 61. Further, the back surface 40a of the flat support portion 40 is supported by a second vertical support portion 62 provided on the second spring portion 50. Therefore, the other connection terminal portion 20 is a flat support portion 40, a first vertical support portion 61 provided on the first spring portion 30, and a second vertical support provided on the second spring portion 50. It is supported by part 62. Therefore, even if the other connection terminal portion 20 is pushed by the electrode terminal 121 of the other substrate 120, the other connection terminal portion 20 does not bend at the upper bent portion 38, and the other connection terminal portion 20 does not bend. The position of the is stable, and an electrical connection with the electrode terminal 121 of the other substrate 120 can be surely obtained.
尚、本実施の形態においては、低背化のため、第１のバネ部３０及び第２のバネ部５０の一部が細く形成されている部分があるが、他方の接続端子部２０が押された際には、他方の接続端子部２０は、平坦支持部４０、第１のバネ部３０に設けられている第１の垂直支持部６１、第２のバネ部５０に設けられている第２の垂直支持部６２により支持される。このため、他方の接続端子部２０が、他方の基板１２０の電極端子１２１により押されても、他方の接続端子部２０は、上部折り曲げ部３８において、曲がることはない。 In the present embodiment, in order to reduce the height, there is a portion where a part of the first spring portion 30 and the second spring portion 50 is formed thinly, but the other connection terminal portion 20 is pressed. When this is done, the other connection terminal portion 20 is provided on the flat support portion 40, the first vertical support portion 61 provided on the first spring portion 30, and the second spring portion 50. It is supported by the vertical support portion 62 of 2. Therefore, even if the other connection terminal portion 20 is pushed by the electrode terminal 121 of the other substrate 120, the other connection terminal portion 20 does not bend at the upper bent portion 38.
更に、図１３に示すように、他方の基板１２０を圧接コネクタの他方の接続端子部２０の側に押す。これにより、第１のバネ部３０及び第２のバネ部５０が、更に変形し、他方の接続端子部２０は裏面が平坦支持部４０と接触している状態のまま一方の接続端子部１０の側に動き、他方の接続端子部２０と一方の接続端子部１０との間が狭くなる。この際、低背化している場合には、一方の接続端子部１０と第１のバネ部３０との間、一方の接続端子部１０と第２のバネ部５０との間は隙間が形成されており、各々の隙間の幅は略等しい。 Further, as shown in FIG. 13, the other substrate 120 is pushed toward the other connection terminal portion 20 of the pressure welding connector. As a result, the first spring portion 30 and the second spring portion 50 are further deformed, and the other connection terminal portion 20 of the one connection terminal portion 10 remains in contact with the flat support portion 40 on the back surface. It moves to the side, and the space between the other connection terminal portion 20 and the one connection terminal portion 10 becomes narrower. At this time, when the height is lowered, a gap is formed between one connection terminal portion 10 and the first spring portion 30, and between one connection terminal portion 10 and the second spring portion 50. The width of each gap is almost equal.
