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。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting substrates and suitable for high-speed transmission of electrical signals. Specifically, the width of the connector from the end of one terminal to the end of the other terminal arranged facing each other in the direction perpendicular to the longitudinal axis of the connector (transverse direction) is defined as the width of the conventional connector. The present invention relates to 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。 2017-069133 (Patent Document 1), for example, discloses a connector in which a plurality of terminals are arrayed and held in a housing by integral molding or the like to connect substrates. The connector is a receptacle-side connector (receptacle connector) connected to a plug-side connector (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 each be provided on a printed wiring board, a flexible flat cable, or the like. The boards can be connected by fitting a receptacle connector provided on the printed wiring board by surface mounting or the like to a plug connector provided at the end of the flexible flat cable.

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 terminals used in conventional connectors. A terminal 900 is a terminal of a plug connector, a 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 , an insertion tip portion 903 and a contact portion 904 . A mounting portion 901 of the terminal 900 is soldered and mounted on a printed wiring board, a flexible flat cable, or the like. By inserting the insertion tip portion 903 toward the inserted portion 1003 between the contact portion 1001 and the contact portion 1004 of the mating terminal 1000 , the contact portions 902 and 904 are connected to the contact portions 1001 and 1004 of the terminal 1000 . The contact portions 1004 can be contacted respectively.

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。 Terminal 1000 includes contact portion 1001 , spring portion 1002 , inserted portion 1003 , contact portion 1004 , U-shaped bent portion 1005 , extension portion 1006 , and mounting portion 1007 . A 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 end portion 903 of the mating terminal 900 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 mating terminal 900 by the elastic force of the spring portion 1002 . Pressed against the portion 902, the contact portion 1001 and the contact portion 1004 can contact the contact portion 902 and the contact portion 904, respectively.

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1001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 sophistication of electronic devices such as smartphones and mobile terminals, there has been progress in high-density mounting of components such as connectors that connect elements and boards on printed wiring boards. There is a need to miniaturize the connector itself. However, the housing of the connector can only be made small enough to hold the terminals, and there is a limit to miniaturization of the connector. For example, as shown in FIG. 16, a terminal 1000 included in a receptacle connector has a shape in which a mounting portion 1007 is provided at a position apart from contact portions 1001 and 1004, so that it is similar to a conventional connector (see Patent Document 1). If the terminals 1000 are symmetrically opposed to each other in the lateral direction of the connector as shown in , the connector width from one terminal end to the other terminal end 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。 In other words, the terminal 1000 of the receptacle connector extends from the side of the inserted portion 1003 into which the mating terminal 900 is inserted through the contact portion 1004, the U-shaped bent portion 1005, and the extended portion 1006 in the lateral direction of the connector ( Since the mounting portion 1007 is provided at a position separated in 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 having the terminals 1000 symmetrically opposed to 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), so that miniaturization is possible. can't

以上のような課題を解決するために、内側脚部と外側脚部とを有する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、当該端子の外側脚部の短手方向(X軸方向)外側を向いた面である支持面を、側壁部によって支持するレセプタクルコネクタであって、外側脚部及び側壁部の元の形状に戻ろうとする力によって、相手側の端子との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を提供する。 In order to solve the above-described problems, the mounting portion, which is provided at a position apart from the inserted portion of the terminal having the inner leg portion and the outer leg portion, is replaced with the substrate side surface of the inserted portion (plug connector). By providing it on the opposite side of the terminal receiving side), the length of the terminal is shortened and the width in the width direction of the connector is narrowed, and the width in the width direction of the outer leg of the terminal A receptacle connector in which a support surface, which is a surface facing (X-axis direction) outward, is supported by a side wall, and the force of the outer leg and the side wall to return to the original shape causes contact with a mating terminal. To provide a receptacle connector capable of maintaining electrical connection between.

Represents the cutting point. 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 line AA in FIG. . FIG. 14 is a view of receptacle connector 700 and plug connector 800 obtained by cutting cutout portion 71 of housing 70 of receptacle connector 700 and side wall portion 83 of housing 80 of plug connector 800 along line BB in FIG. It is a 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70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。 13 and 14, the two terminals 50 of the receptacle connector 700 are symmetrically held by the housing 70 so as to face each other with the fitting protrusion 72 as the center. The two terminals 60 of the plug connector 800 are symmetrically held by the housing 70 so as to face each other centering on 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 portions 51 of the two terminals 50 are supported by the side surfaces of the fitting protrusions 72 provided in the central portion of the housing 70 on the surfaces opposite to the surfaces on which the contact portions 52 are provided. The outer leg portion 55 of the terminal 50 is supported by the side wall portion 73 on the support surface 57 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52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 have a recess in at least part of the surface facing the contact portion 52 . 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 has a protrusion (not shown) protruding from the surface of the contact portion 62 of the terminal 60, the contact recess 58 is formed by the protrusion on the contact portion 62 when the connector is mated. can be locked. 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 can include a covering portion 77 that is filled with resin and covers the inserted portion 53 between the fitting convex portion 72 and the side wall portion 73 . The terminal 50 is firmly fixed to the housing 70 by covering the inserted portion 53 substantially without covering the contact portion 56 , the contact recess 58 and the contact portion 52 without covering the contact portion 56 , the contact recess 58 and the contact portion 52 . The inserted portion 53 is a bent portion between the inner leg portion 51 and the outer leg portion 55, and is the surface opposite to the surface for receiving the terminals 60 of the mating plug connector 800 (that is, the board side ( A mounting portion 54 for mounting on a substrate by soldering or the like is provided on the surface (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 has the thin wall portion 74 on the outer side in the lateral direction (X-axis direction), it is configured to easily spread outward. When the insertion tip portion 66 of the terminal 60 is inserted toward the insertion receiving portion 53 of the terminal 50, the outer leg portion 55 of the terminal 50 has elasticity, so that the outer leg portion 55 of the terminal 50 is pushed outward in the lateral direction (X-axis direction). deformed by being pushed by That is, the outer leg 55 can be displaced away from the inner leg 51 . At this time, the side wall portion 73 having the thin wall portion 74 is also pushed by the support surface 57 of the outer leg portion 55, and is expanded and deformed outward in the lateral direction (X-axis direction). In this manner, the thin wall portion 74 can promote deformation of the side wall portion 73 when the connectors are mated.

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。 15 is a view of the receptacle connector and the plug connector shown in FIG. 10 as viewed from the board side (Z1 side) of the receptacle connector. The housing 70 has grooves 76 that expose the mounting portions 54 of the terminals 50 on the substrate side surface (bottom surface) for each arrangement of the terminals 50 in the longitudinal direction (Y-axis direction). The groove portion 76 can cover the curved mounting portion 54 without gaps so that solder does not enter the inside of the housing 70 from between the mounting portion 54 and the groove portion 76 when the connector 700 is mounted on the substrate. .

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 illustrated embodiments of the present invention, the mounting portion, which is conventionally provided at a position separated from the insertion portion of the terminal in the lateral direction (X-axis direction) of the connector, can be replaced with the insertion portion. By providing the portion on the substrate side surface, the width in the lateral direction can be narrowed and the size of the connector can be reduced.
