Description

本発明は、基板間を接続するためのコネクタであって、電気信号の高速伝送に適したコネクタに関する。具体的には、コネクタの長手方向の軸に対して軸直方向（短手方向）に向い合せに配置された一方の端子の端部から他方の端子の端部までのコネクタ幅を、従来のコネクタよりも狭くすることが可能な端子構造に関する。 The present invention relates to a connector for connecting between substrates and suitable for high-speed transmission of an electric signal. Specifically, the conventional connector width from the end of one terminal to the end of the other terminal, which is arranged so as to face the axis in the longitudinal direction (shortward direction) of the connector. Regarding a terminal structure that can be made narrower than a connector.

複数の端子がハウジングに一体成形等により配列保持され、基板間を接続するコネクタとして、例えば、特開２０１７－０６９１３３号公報（特許文献１）に開示されているコネクタがある。当該コネクタは、プラグ側のコネクタ（プラグコネクタ）と接続されるレセプタクル側のコネクタ（レセプタクルコネクタ）であり、複数の端子を長手方向に配列保持した、長方形状のハウジングを備える。 As a connector in which a plurality of terminals are arranged and held in a housing by integral molding or the like to connect the substrates, for example, there is a connector disclosed in Japanese Patent Application Laid-Open No. 2017-069133 (Patent Document 1). The connector is a connector on the receptacle side (receptacle connector) connected to a connector on the plug side (plug connector), and includes a rectangular housing in which a plurality of terminals are arranged and held in the longitudinal direction.

レセプタクルコネクタ及びプラグコネクタは、それぞれプリント配線基板又はフレキシブルフラットケーブル等に設けることができる。表面実装等でプリント配線基板に設けられたレセプタクルコネクタと、フレキシブルフラットケーブルの端部に設けられたプラグコネクタとを互いに嵌合することで、基板間を接続することができる。 The receptacle connector and the plug connector can be provided on a printed wiring board, a flexible flat cable, or the like, respectively. By mating the receptacle connector provided on the printed wiring board for surface mounting or the like and the plug connector provided at the end of the flexible flat cable to each other, the boards can be connected to each other.

図１６には、従来のコネクタに用いられる端子の一例が示される。端子９００は、プラグコネクタの端子であり、端子１０００は、レセプタクルコネクタの端子であり、各端子の形状は、コネクタの長手方向からみたものである。端子９００は、実装部９０１と、接触部９０２と、嵌入先端部９０３と、接触部９０４とを備える。端子９００の実装部９０１は、半田付けされてプリント配線基板又はフレキシブルフラットケーブル等に実装される。嵌入先端部９０３を相手側の端子１０００の接触部１００１と接触部１００４との間の被嵌入部１００３に向けて嵌入することで、接触部９０２及び接触部９０４が、端子１０００の接触部１００１及び接触部１００４にそれぞれ接触することができる。 FIG. 16 shows an example of a terminal used in a conventional connector. The terminal 900 is a terminal of a plug connector, the terminal 1000 is a terminal of a receptacle connector, and the shape of each terminal is viewed from the longitudinal direction of the connector. The terminal 900 includes a mounting portion 901, a contact portion 902, a fitting tip portion 903, and a contact portion 904. The mounting portion 901 of the terminal 900 is soldered and mounted on a printed wiring board, a flexible flat cable, or the like. By fitting the fitting tip portion 903 toward the fitting portion 1003 between the contact portion 1001 and the contact portion 1004 of the terminal 1000 on the other side, the contact portion 902 and the contact portion 904 become the contact portion 1001 and the contact portion 1001 of the terminal 1000. Each of the contact portions 1004 can be contacted.

端子１０００は、接触部１００１と、バネ部１００２と、被嵌入部１００３と、接触部１００４と、Ｕ字屈曲部１００５と、延長部１００６と、実装部１００７とを備える。端子１０００の実装部１００７は、半田付けされてプリント配線基板又はフレキシブルフラットケーブル等に実装される。相手側の端子９００の嵌入先端部９０３が、端子１０００の接触部１００１と接触部１００４との間に嵌入されると、接触部１００１は、バネ部１００２の弾性力によって相手側の端子９００の接触部９０２に押し当てられ、接触部１００１及び接触部１００４は、接触部９０２及び接触部９０４にそれぞれ接触することができる。 The terminal 1000 includes a contact portion 1001, a spring portion 1002, a fitting portion 1003, a contact portion 1004, a U-shaped bending portion 1005, an extension portion 1006, and a mounting portion 1007. The mounting portion 1007 of the terminal 1000 is soldered and mounted on a printed wiring board, a flexible flat cable, or the like. When the fitting tip portion 903 of the terminal 900 on the mating side is fitted between the contact portion 1001 and the contact portion 1004 of the terminal 1000, the contact portion 1001 is brought into contact with the terminal 900 on the mating side by the elastic force of the spring portion 1002. It is pressed against the portion 902, and the contact portion 1001 and the contact portion 1004 can come into contact with the contact portion 902 and the contact portion 904, respectively.

特開２０１７－０６９１３３号公報Japanese Unexamined Patent Publication No. 2017-069133

近年、スマートフォン、携帯端末等の電子機器の小型化や高機能化等に伴って、プリント配線基板において、素子、基板間を接続するコネクタ等の部品の高密度実装化が進んでおり、部品であるコネクタ自体の小型化する必要がある。しかしながら、端子を保持可能な程度にしか、コネクタのハウジングを小さくすることができず、コネクタの小型化に限界がある。例えば、図１６に示されるように、レセプタクルコネクタに含まれる端子１０００は、接触部１００２及び接触部１００４から離れた位置に実装部１００７を備える形状のために、従来のコネクタ（特許文献１参照）のように、端子１０００をコネクタの短手方向で対称的に対向するように配置すると、一方の端子の端部から他方の端子の端部までのコネクタ幅を狭くすることができない。 In recent years, along with the miniaturization and higher functionality of electronic devices such as smartphones and mobile terminals, high-density mounting of components such as elements and connectors that connect between boards has been progressing in printed wiring boards. It is necessary to reduce the size of a certain connector itself. However, the housing of the connector can be made small only to the extent that the terminals can be held, and there is a limit to the miniaturization of the connector. For example, as shown in FIG. 16, the terminal 1000 included in the receptacle connector has a conventional connector (see Patent Document 1) because of the shape in which the mounting portion 1007 is provided at a position away from the contact portion 1002 and the contact portion 1004. When the terminals 1000 are arranged so as to be symmetrically opposed to each other in the lateral direction of the connector as described above, the connector width from the end of one terminal to the end of the other terminal cannot be narrowed.

つまり、レセプタクルコネクタの端子１０００は、相手側の端子９００が嵌入される被嵌入部１００３がある側から、接触部１００４、Ｕ字屈曲部１００５、延長部１００６を介して、コネクタの短手方向（Ｘ軸方向）に離れた位置に、実装部１００７を備えているため、端子１０００の短手方向（Ｘ軸方向）の長さを短くすることが困難である。そのため、短手方向（Ｘ軸方向）に対称的に向い合せに端子１０００を備えた、従来のレセプタクルコネクタでは、短手方向（Ｘ軸方向）の幅を狭くする余地がほとんどなく小型化することができない。 That is, the terminal 1000 of the receptacle connector is located in the lateral direction of the connector from the side where the mating portion 1003 into which the terminal 900 on the other side is fitted is located, via the contact portion 1004, the U-shaped bent portion 1005, and the extension portion 1006. Since the mounting portion 1007 is provided at a position distant from the X-axis direction, it is difficult to shorten the length of the terminal 1000 in the lateral direction (X-axis direction). Therefore, in the conventional receptacle connector provided with terminals 1000 symmetrically facing each other in the lateral direction (X-axis direction), there is almost no room for narrowing the width in the lateral direction (X-axis direction), and the size can be reduced. I can't.

以上のような課題を解決するために、端子の被嵌入部から離れた位置に設けられていた実装部を、被嵌入部の基板側の面（プラグコネクタの端子を受け入れる側の面とは、反対側の面）に設けることで、端子の長さを短くしてコネクタの短手方向の幅を狭く構成したレセプタクルコネクタを提供する。 In order to solve the above problems, the mounting portion provided at a position away from the fitting portion of the terminal is defined as the surface of the fitting portion on the board side (the surface on the side of receiving the terminal of the plug connector). By providing the connector on the opposite surface), a receptacle connector is provided in which the length of the terminal is shortened and the width in the lateral direction of the connector is narrowed.

図８に示す断面図及び図９に示す断面図を参照すると、レセプタクルコネクタ１００の２つの端子１０は、ハウジング３０によって、嵌合凸部３２を中心に互に向かい合って左右対称に保持される。プラグコネクタ２００の２つの端子２０は、ハウジング３０によって、嵌合凹部４４を中心に互いに向かい合って左右対称に保持される。 Referring to the cross-sectional view shown in FIG. 8 and the cross-sectional view shown in FIG. 9, the two terminals 10 of the receptacle connector 100 are held symmetrically by the housing 30 so as to face each other with respect to the fitting convex portion 32. The two terminals 20 of the plug connector 200 are held symmetrically by the housing 30 so as to face each other with respect to the fitting recess 44.

２つの端子１０の内側脚部１１は、接触部１２がある面とは反対側の面をそれぞれハウジング３０の中央部分に設けられた嵌合凸部３２の側面で支持される。端子１０の外側脚部１５は、短手方向（Ｘ軸方向）外側を向いた面である支持面１７を、側壁部３３によって支持される。２つの端子２０は、実装部２１と嵌入部２４との間の湾曲部分を樹脂で覆うことで支持される。 The inner leg portions 11 of the two terminals 10 are supported on the surface opposite to the surface on which the contact portion 12 is located by the side surface of the fitting convex portion 32 provided in the central portion of the housing 30, respectively. The outer leg portion 15 of the terminal 10 is supported by the side wall portion 33 on the support surface 17, which is a surface facing outward in the lateral direction (X-axis direction). The two terminals 20 are supported by covering the curved portion between the mounting portion 21 and the fitting portion 24 with resin.

端子１０の接触部１６は、側壁部３３の表面よりも嵌合凸部３２側に突出し、一方、端子２０の接触部２２は、側壁部４３の外側の表面よりも短手方向（Ｘ軸方向）外側に出るように構成される。端子１０の接触部１２の表面は、嵌合凸部３２の表面と面一であり、端子２０の接触部２５の表面も、側壁４３の内側の表面と面一である。接触部１６は、接触部１２側に突出し、外側脚部１５と内側脚部１１との間隔は、接触部１６と接触部１２との間で最も狭くなる。 The contact portion 16 of the terminal 10 projects toward the fitting convex portion 32 from the surface of the side wall portion 33, while the contact portion 22 of the terminal 20 is in the lateral direction (X-axis direction) with respect to the outer surface of the side wall portion 43. ) It is configured to go outside.

The contact portion 16 projects toward the contact portion 12, and the distance between the outer leg portion 15 and the inner leg portion 11 is the narrowest between the contact portion 16 and the contact portion 12.

図１０は、本発明の一実施形態に係るレセプタクルコネクタとプラグコネクタとの嵌合状態を示す断面図である。当該断面図は、図７中の線Ａ－Ａに対応する部分で、レセプタクルコネクタ１００とプラグコネクタ２００を切断したものである。端子１０の被嵌入部１３に向けて、端子２０の嵌入先端部２６を侵入させていくと、端子１０の外側脚部１５は弾性を有しているので、短手方向（Ｘ軸方向）外側に押されて変形する。つまり、外側脚部１５は、内側脚部１１から離れる方向に変位することができる。このとき、側壁部３３も外側脚部１５の支持面１７に押されて、短手方向（Ｘ軸方向）外側に拡がり変形する。 FIG. 10 is a cross-sectional view showing a fitted state of the receptacle connector and the plug connector according to the embodiment of the present invention. The cross-sectional view is a portion corresponding to the line AA in FIG. 7, in which the receptacle connector 100 and the plug connector 200 are cut off. When the fitting tip portion 26 of the terminal 20 is inserted toward the fitting portion 13 of the terminal 10, the outer leg portion 15 of the terminal 10 has elasticity, so that it is outside in the lateral direction (X-axis direction). It is pushed by and deformed. That is, the outer leg portion 15 can be displaced in a direction away from the inner leg portion 11. At this time, the side wall portion 33 is also pushed by the support surface 17 of the outer leg portion 15 and expands and deforms outward in the lateral direction (X-axis direction).

外側脚部１５は、もとの状態に戻ろうとする力によって接触部１６を、端子２０の接触部２２に押し当てることで、端子間の電気的接続を保つことができる。レセプタクルコネクタ１００にプラグコネクタ２００から離れる方向（Ｚ１方向）に力が加わった場合、又はプラグコネクタ２００にレセプタクルコネクタ１００から離れる方向（Ｚ２方向）に意図しない力が加わった場合に、接触部２２の表面よりも突出したロック部２３は、接触部１６にひっかかり、簡単に電気的接続が解除されることを防ぐことができる。 The outer leg portion 15 can maintain an electrical connection between the terminals by pressing the contact portion 16 against the contact portion 22 of the terminal 20 by a force that tries to return to the original state. When a force is applied to the receptacle connector 100 in the direction away from the plug connector 200 (Z1 direction), or when an unintended force is applied to the plug connector 200 in the direction away from the receptacle connector 100 (Z2 direction), the contact portion 22 The lock portion 23 protruding from the surface can be prevented from being caught by the contact portion 16 and being easily disconnected from the electrical connection.

嵌入部２４は、外側脚部１５及び側壁部３３の元の形状に戻ろうとする力によって、嵌合凸部３２側に押されて、接触部２５は接触部１２に押し当てられて電気的に接続することができる。２つの端子１０の内側脚部１１は、それぞれ内側（嵌合凸部３２側）に押されるが、嵌合凸部３２は、両側から実質的に均等な力が加わるため、各内側脚部１１は変形することなく嵌合凸部３２で支持される。 The fitting portion 24 is pushed toward the fitting convex portion 32 by a force that tries to return to the original shape of the outer leg portion 15 and the side wall portion 33, and the contact portion 25 is pressed against the contact portion 12 and electrically. You can connect. The inner legs 11 of the two terminals 10 are pushed inward (on the fitting convex portion 32 side), respectively, but the fitting convex portions 32 are subjected to substantially even force from both sides, so that each inner leg portion 11 is applied. Is supported by the fitting protrusion 32 without deformation.

Represents the cut location. FIG. 13 is a cross-sectional view of the receptacle connector 700 and the plug connector 800 in which the terminal 50 portion included in the receptacle connector 700 and the terminal 60 portion included in the plug connector 800 are cut along the lines AA in FIG. .. FIG. 14 shows the receptacle connector 700 and the plug connector 800 in which the notch 71 portion of the housing 70 of the receptacle connector 700 and the side wall portion 83 portion of the housing 80 of the plug connector 800 are cut along the line BB in FIG. It is a cross-sectional view.

図１３に示す断面図及び図１４に示す断面図を参照すると、レセプタクルコネクタ７００の２つの端子５０は、ハウジング７０によって、嵌合凸部７２を中心に互に向かい合って左右対称に保持される。プラグコネクタ８００の２つの端子６０は、ハウジング６０によって、嵌合凹部８４を中心に互いに向かい合って左右対称に保持される。 Referring to the cross-sectional view shown in FIG. 13 and the cross-sectional view shown in FIG. 14, the two terminals 50 of the receptacle connector 700 are held symmetrically by the housing 70 so as to face each other with respect to the fitting convex portion 72. The two terminals 60 of the plug connector 800 are held symmetrically by the housing 60 so as to face each other with respect to the fitting recess 84.

２つの端子５０の内側脚部５１は、接触部５２がある面とは反対側の面をそれぞれハウジング７０の中央部分に設けられた嵌合凸部７２の側面で支持される。端子５０の外側脚部５５は、短手方向（Ｘ軸方向）外側を向いた面である支持面５７を、側壁部７３によって支持される。２つの端子６０は、実装部６１と嵌入部６４との間の湾曲部分を樹脂で覆うことで支持される。 The inner leg 51 of the two terminals 50 is supported on a surface opposite to the surface on which the contact portion 52 is located by the side surface of the fitting convex portion 72 provided in the central portion of the housing 70, respectively. The outer leg portion 55 of the terminal 50 is supported by the side wall portion 73 on the support surface 57, which is a surface facing outward in the lateral direction (X-axis direction). The two terminals 60 are supported by covering the curved portion between the mounting portion 61 and the fitting portion 64 with resin.

接触部５６は、接触部５１と対向する面の少なくとも一部に凹部を設けてもよい。図１３に示されるように、端子５０の接触部５６は、表面を凹状に窪ませた接触凹部５８を備えることができる。接触凹部５８は、端子６０の接触部６２の表面に、該表面から突出した凸部（図示せず）を設けた場合に、コネクタの嵌合時に、接触凹部５８は接触部６２上の凸部に係止することができる。接触部５６の表面は、側壁部６３の表面と面一である。 The contact portion 56 may be provided with a recess in at least a part of the surface facing the contact portion 51. As shown in FIG. 13, the contact portion 56 of the terminal 50 may include a contact recess 58 having a concave surface. When the contact recess 58 is provided with a convex portion (not shown) protruding from the surface of the contact portion 62 of the terminal 60, the contact recess 58 is a convex portion on the contact portion 62 when the connector is fitted. Can be locked to. The surface of the contact portion 56 is flush with the surface of the side wall portion 63.

ハウジング７０は、嵌合凸部７２と側壁部７３との間に、樹脂が充填され被嵌入部５３を覆った被覆部７７を備えることができる。被覆部７７は、接触部５６、接触凹部５８及び接触部５２を覆うことなく、被嵌入部５３を実質的に隙間なく覆うことで、端子５０は、ハウジング７０に強固に固定される。被嵌入部５３は、内側脚部５１と外側脚部５５との間の屈曲した部分であり、相手コネクタであるプラグコネクタ８００の端子６０を受け入れる面とは反対側の面（すなわち、基板側（Ｚ１側）の面）に、半田付け等で基板に実装するための実装部５４を有する。 The housing 70 may include a covering portion 77, which is filled with resin and covers the fitted portion 53, between the fitting convex portion 72 and the side wall portion 73. The covering portion 77 does not cover the contact portion 56, the contact recess 58, and the contact portion 52, but covers the fitted portion 53 with substantially no gap, so that the terminal 50 is firmly fixed to the housing 70. The fitting portion 53 is a bent portion between the inner leg portion 51 and the outer leg portion 55, and is a surface opposite to the surface receiving the terminal 60 of the plug connector 800 which is the mating connector (that is, the substrate side (that is, the substrate side (that is, the substrate side). A mounting portion 54 for mounting on a substrate by soldering or the like is provided on the surface) on the Z1 side).

側壁部７３は、短手方向（Ｘ軸方向）外側に薄壁部７４を備えているので、外側に拡がり易く構成されている。端子５０の被嵌入部５３に向けて、端子６０の嵌入先端部６６を侵入させていくと、端子５０の外側脚部５５は弾性を有しているので、短手方向（Ｘ軸方向）外側に押されて変形する。つまり、外側脚部５５は、内側脚部５１から離れる方向に変位することができる。このとき、薄壁部７４を備えた側壁部７３も外側脚部５５の支持面５７に押され、短手方向（Ｘ軸方向）外側に拡がり変形する。このように、薄壁部７４は、コネクタの嵌合時に、側壁部７３の変形を促すことができる。 Since the side wall portion 73 is provided with the thin wall portion 74 on the outer side in the lateral direction (X-axis direction), the side wall portion 73 is configured to be easily spread outward. When the fitting tip 66 of the terminal 60 is inserted toward the fitting portion 53 of the terminal 50, the outer leg portion 55 of the terminal 50 has elasticity, so that it is outside in the lateral direction (X-axis direction). It is pushed by and deformed. That is, the outer leg portion 55 can be displaced in a direction away from the inner leg portion 51. At this time, the side wall portion 73 provided with the thin wall portion 74 is also pushed by the support surface 57 of the outer leg portion 55, and expands and deforms outward in the lateral direction (X-axis direction). In this way, the thin wall portion 74 can promote the deformation of the side wall portion 73 when the connector is fitted.

図１５は、図１０に示すレセプタクルコネクタとプラグコネクタをレセプタクルコネクタの基板側（Ｚ１側）からみた図である。ハウジング７０は、端子５０の長手方向（Ｙ軸方向）の配列毎に、基板側の面（底面）に、端子５０の実装部５４を露出させた溝部７６を備える。溝部７６は、コネクタ７００を基板に実装する際に、半田が実装部５４と溝部７６との間からハウジング７０の内部に侵入しないように、湾曲した実装部５４の周りを隙間なく覆うことができる。 FIG. 15 is a view of the receptacle connector and the plug connector shown in FIG. 10 as viewed from the substrate side (Z1 side) of the receptacle connector. The housing 70 includes a groove portion 76 in which the mounting portion 54 of the terminal 50 is exposed on the surface (bottom surface) on the substrate side for each arrangement in the longitudinal direction (Y-axis direction) of the terminals 50. When the connector 700 is mounted on the substrate, the groove portion 76 can cover the curved mounting portion 54 without a gap so that the solder does not enter the inside of the housing 70 from between the mounting portion 54 and the groove portion 76. ..

以上のとおり、本発明は、例示したいずれの実施形態においても、従来、端子の被嵌入部からコネクタの短手方向（Ｘ軸方向）に離れた位置に設けられていた実装部を、被嵌入部の基板側の面に設けたことで、短手方向の幅を狭くしてコネクタの小型化をすることができる。本発明の個々の実施形態は、独立したものではなく、それぞれ組み合わせて適宜実施することができる。 As described above, in any of the exemplified embodiments, the present invention conventionally fits the mounting portion provided at a position away from the fitting portion of the terminal in the lateral direction (X-axis direction) of the connector. By providing the portion on the surface on the board side, the width in the lateral direction can be narrowed and the size of the connector can be reduced. The individual embodiments of the present invention are not independent, and can be appropriately implemented in combination with each other.

本発明に係るコネクタは、電気信号の高速伝送を行うスマートフォン、携帯電話等の電子機器において、基板間をフラットケーブルで接続する等の用途に利用することができる。 The connector according to the present invention can be used for applications such as connecting substrates with a flat cable in electronic devices such as smartphones and mobile phones that transmit electric signals at high speed.
