Description

本発明は、それぞれが互いに異なる基板に実装され、これら基板を互いに接続する２つのコネクタ、いわゆるボード・トゥ・ボードコネクタを備えた電気コネクタに関する。   The present invention relates to an electrical connector provided with two connectors, so-called board-to-board connectors, which are mounted on different substrates and connect these substrates to each other.

従来から、板状のプリント配線基板（以下、ＰＣＢともいう）同士を互いに接続（いわゆるボード・トゥ・ボード接続）する電気コネクタが広く使われている。この電気コネクタは、互いに異なる基板に実装され、互いに嵌合するリセプタクルコネクタとプラグコネクタを備えており、これらリセプタクルコネクタとプラグコネクタを嵌合させることによりＰＣＢ同士が接続される。リセプタクルコネクタとプラグコネクタはそれぞれ、複数のコンタクトと、これらコンタクトが所定のピッチに配列されたハウジングを備えている。通常、リセプタクルコネクタのハウジングに配列されたコンタクトはばね性をもっており、リセプタクルコネクタとプラグコネクタが嵌合されると、それぞれのハウジングに配列されたコンタクト同士はこのばね性により所定の圧力で接触して電気的に接続される。   Conventionally, electrical connectors for connecting plate-like printed wiring boards (hereinafter also referred to as PCBs) to each other (so-called board-to-board connection) have been widely used. This electrical connector includes a receptacle connector and a plug connector that are mounted on different substrates and fit to each other, and the PCBs are connected to each other by fitting the receptacle connector and the plug connector. Each of the receptacle connector and the plug connector includes a plurality of contacts and a housing in which the contacts are arranged at a predetermined pitch. Normally, the contacts arranged in the housing of the receptacle connector have a spring property, and when the receptacle connector and the plug connector are fitted, the contacts arranged in the respective housings contact with each other with a predetermined pressure due to this spring property. Electrically connected.

このボード・トゥ・ボードコネクタの中には、たとえば、連結凸部を有するプラグコネクタと、連結凹部を有するリセプタクルコネクタとからなり、プラグコネクタの連結凸部をリセプタクルコネクタの連結凹部に嵌合させることにより、それぞれのコネクタのコンタクト（接点）同士が接続され、ボード・トゥ・ボード接続が達成されるようになっているものがある。   The board-to-board connector includes, for example, a plug connector having a connecting convex portion and a receptacle connector having a connecting concave portion, and the connecting convex portion of the plug connector is fitted into the connecting concave portion of the receptacle connector. In some cases, the contacts (contacts) of the respective connectors are connected to each other to achieve board-to-board connection.

近年、各種電気機器（パーソナルコンピュータ、液晶表示装置などの電子機器）の小型化が進むにつれて、上記のようなボード・トゥ・ボードコネクタの小型化および薄型化が望まれている。しかしながら、上記のようなタイプのボード・トゥ・ボードコネクタを薄型化するためには、連結凸部の高さを低くして、連結凹部の深さを浅くしなければならない。１対の配線基板の表面にそれぞれ取り付けられたコネクタ（プラグコネクタおよびリセプタクルコネクタ）をボード・トゥ・ボード接続する場合には、これらの１対のコネクタを互いに擦り合わせるようにして位置合わせを行わなければならないので、連結凸部の高さを低くして、連結凹部の深さを浅くした場合には、連結凹部と連結凸部との当たり部分が小さくなり、位置合わせしにくくなる。   In recent years, as various electric devices (electronic devices such as personal computers and liquid crystal display devices) have been reduced in size, it has been desired to reduce the size and thickness of the board-to-board connector as described above. However, in order to make a board-to-board connector of the type described above thinner, it is necessary to reduce the height of the connecting projection and reduce the depth of the connecting recess. When board-to-board connectors (plug connectors and receptacle connectors) respectively attached to the surface of a pair of wiring boards are to be aligned by rubbing the pair of connectors together. Therefore, when the height of the connecting convex portion is lowered and the depth of the connecting concave portion is made shallow, the contact portion between the connecting concave portion and the connecting convex portion becomes small, and alignment becomes difficult.

そこで、特許文献１には、一方向に長尺の形状を有するコネクタ同士を位置合わせする場合、特に長手方向の位置合わせが容易にできるように、各コネクタの短手方向の幅がある程度合うようにして長手方向に相対的に変位させることにより、プラグコネクタ５の端部の突出片をリセプタクルコネクタ３の突出部の内側面（規制面）に衝突させるようにするものが提案されている。
特開２００４−２７３２７７号公報 Therefore, in Patent Document 1, when connectors having long shapes in one direction are aligned with each other, the width in the short direction of each connector is matched to some extent so that the alignment in the longitudinal direction can be easily performed. Thus, it has been proposed that the projecting piece at the end of the plug connector 5 is made to collide with the inner surface (regulating surface) of the projecting portion of the receptacle connector 3 by being displaced relatively in the longitudinal direction.
JP 2004-273277 A

一方向に長尺の形状を有するコネクタ同士を位置合わせする場合、短手方向の位置合わせを行うときには、長手方向に沿った比較的長い当たり部分に対して位置合わせを行うことができ、位置合わせが比較的容易である。しかしながら、長手方向の位置合わせを行うときに、長手方向に相対的に変位させるため、短手方向に沿った位置合わせが変わることもある。   When aligning connectors that have a long shape in one direction, when aligning in the short direction, the alignment can be performed on a relatively long contact portion along the longitudinal direction. Is relatively easy. However, when the alignment in the longitudinal direction is performed, the alignment along the short side direction may change because the relative displacement is caused in the longitudinal direction.

この発明は、かかる背景のもとでなされたもので、位置合わせが確実にできる電気コネクタを提供することを目的とする。   The present invention has been made in view of such a background, and an object thereof is to provide an electrical connector that can be reliably aligned.

以下、図面を参照して本発明の電気コネクタの実施形態を説明する。
図１から図５までを参照して本発明の電気コネクタの第１実施形態を説明する。 Embodiments of the electrical connector of the present invention will be described below with reference to the drawings.
A first embodiment of the electrical connector of the present invention will be described with reference to FIGS.

図１及び図２は電気コネクタのうちのリセプタクルコネクタ２０（本発明にいう第１のコネクタの一例）を示し、図３乃至図６は電気コネクタのうちのプラグコネクタ６０（本発明にいう第２のコネクタの一例）を示し、図７はこれらリセプタクルコネクタ２０とプラグコネクタ６０が嵌合した状態の電気コネクタ１０の断面を示す。   1 and 2 show a receptacle connector 20 (an example of a first connector according to the present invention) of an electrical connector, and FIGS. 3 to 6 show a plug connector 60 (a second connector according to the present invention) of the electrical connector. FIG. 7 shows a cross section of the electrical connector 10 in a state in which the receptacle connector 20 and the plug connector 60 are fitted.

このボード・トゥ・ボードコネクタである電気コネクタ１０は、図７に示すように、連結凹部としての嵌合凹部３２を有するリセプタクルコネクタ２０と、嵌合凹部３２に対応する形状の連結凸部としての嵌合凸部７２を有するプラグコネクタ６０とを備えている。各コネクタ２０，６０は、たとえば平面視で長方形形状を有していて、それぞれ配線基板１２，１４の実装面上に半田付けによって実装されて用いられる。嵌合凹部３２を有するリセプタクルコネクタ２０と嵌合凸部７２を有するプラグコネクタ６０を嵌合すると、基板１２，１４は互いに直交する状態に接続される。   As shown in FIG. 7, the electrical connector 10, which is a board-to-board connector, includes a receptacle connector 20 having a fitting recess 32 as a connecting recess, and a connecting projection having a shape corresponding to the fitting recess 32. And a plug connector 60 having a fitting projection 72. Each connector 20, 60 has, for example, a rectangular shape in plan view, and is used by being mounted on the mounting surface of the wiring boards 12, 14 by soldering. When the receptacle connector 20 having the fitting concave portion 32 and the plug connector 60 having the fitting convex portion 72 are fitted, the substrates 12 and 14 are connected in a state orthogonal to each other.

図１において、リセプタクルコネクタ２０は、ハウジング３０とコンタクト５０（本発明にいう第１のコンタクトの一例）とを備える。ハウジング３０は、略長尺四角枠状に突出する環状凸部３１と、この環状凸部３１に囲われて形成される嵌合凹部３２と、環状凸部３１の長手方向の両端に一体に設けられたベース３３とを備える。このベース３３には、基板１２の固定用パットに半田付けされる固定用金具３６が備えられている。   In FIG. 1, a receptacle connector 20 includes a housing 30 and a contact 50 (an example of a first contact referred to in the present invention). The housing 30 is integrally provided at both ends in the longitudinal direction of the annular convex portion 31, an annular convex portion 31 projecting in a substantially long rectangular frame shape, a fitting concave portion 32 formed by being surrounded by the annular convex portion 31. Provided base 33. The base 33 is provided with a fixing bracket 36 that is soldered to a fixing pad of the substrate 12.

ハウジング３０の環状凸部３１は、当該リセプタクルコネクタ２０の長手方向に沿って長尺四角枠形状に延びており、長手方向側壁３７と、短手方向側壁３８とを備えて成る。 Annular projection 31 of the housing 30 along the longitudinal direction of the receptacle connector 20 extends in a long rectangular frame shape, and includes a longitudinal Direction side wall 37, and a Tantekata direction side wall 38.

この環状凸部３１の四隅のうち、一方の長手方向側壁３７の両端に位置する２隅（両側の短手方向側壁３８の４つの端うち、一方の長手方向側壁３７に接する２つの端）に、リブ４０が突設されている。このリブ４０は、後述する逃がし穴８０に嵌入し易いように、裁頭４角錘形状の先細りテーパ状に形成されている。また、リブ４０の強度のある大きさを確保する為に、短手方向側壁３８の約半分が長手方向に厚みを増やして形成されている。   Out of the four corners of the annular protrusion 31, two corners located at both ends of one longitudinal side wall 37 (two ends in contact with one longitudinal side wall 37 among the four ends of the lateral side walls 38 on both sides). The rib 40 is projected. The rib 40 is formed in a tapered taper shape having a truncated quadrangular pyramid shape so that the rib 40 can be easily fitted into an escape hole 80 described later. Further, in order to ensure a strong size of the rib 40, about half of the lateral side wall 38 is formed with an increased thickness in the longitudinal direction.

また、短手方向側壁３８のうち、前記リブ４０に隣接する位置に、ガイド部としてのガイド溝４５が設けられている。このガイド溝４５は、嵌合凹部３２の短手方向の幅と略同じ幅ｗ１を有している。すなわち、ガイド溝４５の幅ｗ１は、後述するプラグコネクタ６０の嵌合凸部７２の先端が嵌まった状態でガイドすることができる幅となっている。また、ガイド溝４５の深さｈ１は、後述するプラグコネクタ６０の嵌合凸部７２の先端が外れない程度の深さであって、隣接するリブ４０が後述するプラグコネクタ６０の環状凹部７１に入ったときに、環状凹部７１の底まで届かないような深さとなっている。なお、ガイド部としてガイド溝４５とすることが好ましいが、ｈ＝０となったガイド面であってもよい。このガイド面の場合、環状凹部７１にリブ４０が入り、ガイド面が嵌合凸部７２の先端に当たることで、リブ４０の入る程度が制限され、嵌合凹部１に入ったリブ４０で短手方向がガイドされる。   Further, a guide groove 45 as a guide portion is provided in a position adjacent to the rib 40 in the short side wall 38. The guide groove 45 has a width w1 that is substantially the same as the width of the fitting recess 32 in the lateral direction. That is, the width w1 of the guide groove 45 is a width that can be guided in a state in which the tip of the fitting convex portion 72 of the plug connector 60 described later is fitted. Further, the depth h1 of the guide groove 45 is such a depth that the tip of the fitting convex portion 72 of the plug connector 60 described later cannot be removed, and the adjacent rib 40 is formed in the annular concave portion 71 of the plug connector 60 described later. When entering, the depth is such that it does not reach the bottom of the annular recess 71. The guide groove 45 is preferably used as the guide portion, but may be a guide surface where h = 0. In the case of this guide surface, the rib 40 enters the annular recess 71 and the guide surface hits the tip of the fitting projection 72, so that the extent of the rib 40 is limited, and the rib 40 entering the fitting recess 1 is short. Direction is guided.

前述した環状凸部３１の内側部分を構成する嵌合凹部３２の長手方向に沿った内側面、即ち長手方向側壁３７の内側面には、それぞれ、プラグコネクタ６０との電気的な接続を達成するための複数（たとえば、２０〜１６０個ずつ）のコンタクト５０が、嵌入状態で配設されている。複数のコンタクト５０は、長手方向に沿って等間隔（たとえば、０．３ｍｍピッチ程度）を空けて配置されている。   Electrical connection with the plug connector 60 is achieved respectively on the inner side surface along the longitudinal direction of the fitting concave portion 32 constituting the inner portion of the annular convex portion 31 described above, that is, on the inner side surface of the longitudinal side wall 37. A plurality of (for example, 20 to 160) contacts 50 are arranged in a fitted state. The plurality of contacts 50 are arranged at equal intervals (for example, about 0.3 mm pitch) along the longitudinal direction.

各コンタクト５０は、たとえば、金属板の打ち抜き加工によって作製されたものである。図２のように、各コンタクト５０は、長手方向側壁３７のスリット３７１に嵌入されて固定される基部５１と、この基部５１の端部から先端に向けて延在し、嵌合凹部３２に向かって山折り状に屈曲した形状であって、その先端がプラグコネクタ５に対する接点を構成する接点部５２と、基部５１から短手方向外方に突出し、当該コンタクト５０を配線基板１２の実装面上のランドに半田付けするためのリード部５３とを有している。接点部５２は、基部５１に対して片持ち状に弾性変形できるようになっている。この接点部５２の先端５２１は、ハウジング４０の長手方向側壁３７に形成された係止孔３７２の端に係止されている。 Each contact 50 is made, for example, by punching a metal plate. As shown in FIG. 2, each contact 50 has a base 51 fitted and fixed in the slit 371 of the longitudinal side wall 37, and extends from the end of the base 51 toward the tip and toward the fitting recess 32. And the tip of the contact portion 52 forms a contact point with respect to the plug connector 5 and the base portion 51 protrudes outward in the short direction, and the contact 50 is formed on the mounting surface of the wiring board 12. And a lead portion 53 for soldering to the land. The contact portion 52 can be elastically deformed in a cantilevered manner with respect to the base portion 51. The tip 521 of the contact portion 52 is locked in the longitudinal side walls 37 the edge of locking hole 37 2 formed on the housing 40.

この実施形態では、嵌合凹部３２に臨む長手方向側壁３７の両内面側に沿って配置された複数のコンタクト５０は、左右対称に配置されている。各コンタクト５０の基部５１をハウジング３０の長手方向側壁３７の内側に形成されたスリット３７１に対して基板の取付側から圧入すると、基部５１がハウジング３０の側面に沿った状態となり、リード部５３がハウジング３０の底から外方に突出する。当該リセプタクルコネクタ２０を配線基板１２に取り付ける場合には、ハウジング３０の底面から突出したリード部５３と、配線基板１２の実装面上のランドとの当接部に半田付けを行うことにより、当該当接部の周囲が半田フィレットで覆われて、リセプタクルコネクタ２０が配線基板１２に対して固定される。 In this embodiment, the plurality of contacts 50 arranged along both inner surfaces of the longitudinal side wall 37 facing the fitting recess 32 are arranged symmetrically. When the base portion 51 of each contact 50 is press-fitted from the mounting side of the substrate into the slit 371 formed inside the longitudinal side wall 37 of the housing 30, the base portion 51 is in a state along the side surface of the housing 30, and the lead portion 53 is Projecting outward from the bottom of the housing 30. When attaching the receptacle connector 20 to the wiring board 12, soldering is performed on the contact portion between the lead portion 53 protruding from the bottom surface of the housing 30 and the land on the mounting surface of the wiring substrate 12, thereby The periphery of the contact portion is covered with a solder fillet, and the receptacle connector 20 is fixed to the wiring board 12.

一方、図３において、プラグコネクタ６０は、ハウジング７０とコンタクト９０（本発明にいう第２のコンタクトの一例）を備える。ハウジング７０は、略長尺四角枠状に陥没する環状凹部７１と、この環状凹部７１に囲われて形成される嵌合凸部７２とを備える。   On the other hand, in FIG. 3, the plug connector 60 includes a housing 70 and a contact 90 (an example of a second contact referred to in the present invention). The housing 70 includes an annular recess 71 that is recessed into a substantially long rectangular frame shape, and a fitting projection 72 that is formed so as to be surrounded by the annular recess 71.

ハウジング７０の環状凹部７１は、エンド部７３と、このエンド部７３の周囲に長尺四角枠形状に立設される側壁７４と、エンド部７３の中央に立設される中央壁でもある嵌合凸部７２とを備える。側壁７４は、長手方向側壁７５と、短手方向側壁７６とからなる。長手方向側壁７５の一方には、基板１４の固定用パットに半田付けされる固定用金具７９が備えられている。   The annular recess 71 of the housing 70 is a fitting that is also an end portion 73, a side wall 74 erected in the shape of a long rectangular frame around the end portion 73, and a central wall erected at the center of the end portion 73. And a convex portion 72. The side wall 74 includes a long side wall 75 and a short side wall 76. One of the longitudinal side walls 75 is provided with a fixing bracket 79 that is soldered to a fixing pad of the substrate 14.

この環状凹部７１の四隅のうち、一方の長手方向側壁７５の両端に位置する２隅（両側の短手方向側壁７６の４つの端うち、一方の長手方向側壁７５に接する２つの端）に、逃がし穴８０が設けられている。この逃がし穴８０は、前述したリブ４０が嵌入し易いように、裁頭４角錘穴形状の先細りテーパ穴状に形成されている（図５参照）。また、逃がし穴８０が設けられ二つの隅に対向する二つの隅には、短手方向側壁７６の厚みを長手方向内側に増やして、その上に受け面８５が形成されている。この受け面８５は、図６に示すように、短手方向からみて、逃がし穴８０と重なる位置に設けられ、受けとは逆のテーパ（角度α）となった浅い斜面８５１と、当たり面８５２とを備える。この斜面８５１は、逆嵌合時のリブ４０の先端を誘い込むためのものである。当たり面８５２は、逆嵌合時のリブ４０の端が当たって止めるためのものである。   Of the four corners of the annular recess 71, two corners located at both ends of one longitudinal side wall 75 (two ends in contact with one longitudinal side wall 75 among the four ends of the lateral side walls 76 on both sides) An escape hole 80 is provided. The relief hole 80 is formed in a tapered tapered hole shape having a truncated quadrangular pyramid hole shape so that the above-described rib 40 can be easily inserted (see FIG. 5). Further, relief holes 80 are provided, and at two corners facing the two corners, the thickness of the short side wall 76 is increased inward in the longitudinal direction, and a receiving surface 85 is formed thereon. As shown in FIG. 6, the receiving surface 85 is provided at a position overlapping the escape hole 80 when viewed from the short direction, and has a shallow slope 851 having a taper (angle α) opposite to the receiving surface, and a contact surface 852. With. The slope 851 is for guiding the tip of the rib 40 during reverse fitting. The contact surface 852 is for stopping the end of the rib 40 at the time of reverse fitting.

前述した嵌合凸部（中央壁）７２の長手方向の両外側面には、それぞれ、リセプタクルコネクタ２０との電気的な接続を達成するための複数（たとえば、２０〜１２０個ずつ）のコンタクト９０が、環状凹部７１の内方に臨んでいる。複数のコンタクト９０は、嵌合凸部72にリセプタクルコネクタ２０の嵌合凹部３２が嵌合したときに、当該嵌合凹部３２から外方に臨む複数のコンタクト５０と１対１に対向するように、長手方向に沿って等間隔（たとえば、０．３ｍｍピッチ程度）を空けて配置されている。   A plurality of (for example, 20 to 120) contacts 90 for achieving electrical connection with the receptacle connector 20 are provided on both outer side surfaces in the longitudinal direction of the fitting convex portion (center wall) 72 described above. However, it faces the inside of the annular recess 71. The plurality of contacts 90 face the plurality of contacts 50 facing outward from the fitting recess 32 when the fitting recess 32 of the receptacle connector 20 is fitted to the fitting projection 72. These are arranged at equal intervals (for example, about 0.3 mm pitch) along the longitudinal direction.

各コンタクト９０は、たとえば、金属板の打ち抜き加工によって作製されたものである。図４のように、各コンタクト９０は、ハウジング７０のエンド部７３を短手方向に延びる基部９１と、この基部９１から嵌合凸部７２に沿って延在し、その先端がリセプタクルコネクタ２０に対する接点を構成する接点部９２と、基部９１から下方に突出し、当該コンタクト９０を配線基板１４の実装面上のランドに半田付けするためのリード部９３と、基部９１から突出し、当該コンタクト９０をハウジング７０に対して把持するための把持部９４とを有している。二列のコンタクト９０のうち一方は、ハウジング７０のエンド部７３の側から圧入できるように、ハウジング７０に設けられたスリット７０１に圧入される。二列のコンタクト９０のうち他方は、ハウジング７０の中央壁７２の側から圧入できるように、ハウジング７０に設けられたスリット７０２に圧入される。   Each contact 90 is made, for example, by punching a metal plate. As shown in FIG. 4, each contact 90 extends from the base portion 91 along the fitting convex portion 72 through the end portion 73 of the housing 70 in the short direction, and the tip of the contact 90 extends to the receptacle connector 20. A contact portion 92 that constitutes a contact, a lead portion 93 for projecting downward from the base portion 91 and soldering the contact 90 to a land on the mounting surface of the wiring board 14, a projecting portion from the base portion 91, and housing the contact 90 And a gripping portion 94 for gripping 70. One of the two rows of contacts 90 is press-fitted into a slit 701 provided in the housing 70 so as to be press-fitted from the end portion 73 side of the housing 70. The other of the two rows of contacts 90 is press-fitted into a slit 702 provided in the housing 70 so as to be press-fitted from the central wall 72 side of the housing 70.

この実施形態では、嵌合凸部７２の両外側面に沿って配置された複数のコンタクト９０は、ハウジング７０のエンド部７３の側から圧入できるに適したものと、ハウジング７０の嵌合凸部７２の側から圧入できるのに適したものとの二種類があって、この二種類のコンタクト９０が、それぞれ、ハウジング７０の一方の長手方向側壁において基板１４に固定される。当該プラグコネクタ６０を配線基板１４に取り付ける場合には、ハウジング７０の一方の長手方向側壁７５から突出したリード部９３と、配線基板１４の実装面上のランドとの当接部に半田付けを行うことにより、当該当接部の周囲が半田フィレットで覆われて、プラグコネクタ６０が配線基板１４に対して固定される。
In this embodiment, the plurality of contacts 90 arranged along both outer surfaces of the fitting convex portion 72 are suitable for being press-fitted from the end portion 73 side of the housing 70, and the fitting convex portion of the housing 70. There are two types, one suitable for being press-fit from the 72 side, and the two types of contacts 90 are each fixed to the substrate 14 on one longitudinal side wall of the housing 70. When the plug connector 60 is attached to the wiring board 14, soldering is performed on the contact portion between the lead portion 93 protruding from one longitudinal side wall 75 of the housing 70 and the land on the mounting surface of the wiring substrate 14. Thus, the periphery of the contact portion is covered with the solder fillet, and the plug connector 60 is fixed to the wiring board 14.

図８は、リセプタクルコネクタ２０とプラグコネクタ６０とを嵌合させる手順を示す図である。   FIG. 8 is a diagram showing a procedure for fitting the receptacle connector 20 and the plug connector 60 together.

このボード・トゥ・ボードコネクタである電気コネクタ１０を接続させる場合、作業者は、たとえば、一方の手にリセプタクルコネクタ２０が取り付けられた配線基板１２を持ち、他方の手にプラグコネクタ６０が取り付けられた配線基板１４を持って、各配線基板１２，１４の実装面を互いに交差させた状態から、リセプタクルコネクタ２０の表面（配線基板１２と反対側の表面）に対してプラグコネクタ６０の表面（配線基板１４と直交する表面）を擦り合わせるようにして位置合わせを行う。   When connecting the electrical connector 10 which is this board-to-board connector, for example, the operator has the wiring board 12 with the receptacle connector 20 attached to one hand and the plug connector 60 attached to the other hand. From the state where the mounting surfaces of the wiring boards 12 and 14 are crossed with each other with the wiring board 14 held, the surface of the plug connector 60 (wiring) with respect to the surface of the receptacle connector 20 (surface opposite to the wiring board 12). The alignment is performed by rubbing the surface orthogonal to the substrate 14.

まず、リセプタクルコネクタ２０の環状凸部３１の一方の長手方向側壁３７の両端側に突出するリブ４０によって、リセプタクルコネクタ２０は、長手方向の中心線に対して非対称形状となっている（図１参照）。そのため、視覚的にも、リセプタクルコネクタ２０の方向性の判断がし易くなる。   First, the receptacle connector 20 has an asymmetric shape with respect to the center line in the longitudinal direction by the ribs 40 projecting to both ends of one longitudinal side wall 37 of the annular convex portion 31 of the receptacle connector 20 (see FIG. 1). ). Therefore, the directionality of the receptacle connector 20 can be easily determined visually.

また、プラグコネクタ６０の環状凹部の一方の長手方向側壁の両端側に設けられた逃がし穴８０と、プラグコネクタ６０の環状凹部の他方の長手方向側壁の両端側に設けられた受け面８５とによって、プラグコネクタ６０は、長手方向の中心線に対して非対称形状となっている（図３参照）。そのため、リブ４０が突出するリセプタクルコネクタ２０ほどではないが、視覚的にも、プラグコネクタ６０の方向性の判断がし易くなる。
Moreover, the relief holes 80 provided at both sides of one longitudinal side wall of the annular recess of the plug connector 60, the receiving surface 85 provided on both ends of the other longitudinal side wall of the annular recess of the plug connector 60 by The plug connector 60 has an asymmetric shape with respect to the center line in the longitudinal direction (see FIG. 3). Therefore, although not as much as the receptacle connector 20 from which the rib 40 protrudes, the directionality of the plug connector 60 can be easily determined visually.

このリセプタクルコネクタ２０をプラグコネクタ６０に対して位置合わせする場合には、まず、プラグコネクタ６０の環状凹部の側に、リセプタクルコネクタ２０の環状凸部の側を向かい合わせる。このとき、リセプタクルコネクタ２０とプラグコネクタ６０との長手方向の位置合わせはずれたままでよい。リセプタクルコネクタ２０の一方のリブ４０をプラグコネクタ６０の環状凹部７１を入れる（図８（ａ）参照）。すると、リセプタクルコネクタ２０ガイド溝４５がプラグコネクタ６０の嵌合凸部（中央壁）７２に嵌まり込み、また、リブ４０が環状凹部７１に入ることにより、リセプタクルコネクタ２０の短手方向とプラグコネクタ６０の短手方向がずれないように案内される（図８（ｂ）参照）。この状態で、リセプタクルコネクタ２０を長手方向に向かって斜めに押すと、リセプタクルコネクタ２０のガイド溝４５がプラグコネクタ６０の嵌合凸部（中央壁）７２に沿って、長手方向奥側に向かって移動をする。   When positioning the receptacle connector 20 with respect to the plug connector 60, first, the annular convex side of the receptacle connector 20 is opposed to the annular concave side of the plug connector 60. At this time, the longitudinal alignment between the receptacle connector 20 and the plug connector 60 may remain shifted. An annular recess 71 of the plug connector 60 is inserted into one rib 40 of the receptacle connector 20 (see FIG. 8A). Then, the receptacle connector 20 guide groove 45 fits into the fitting convex portion (center wall) 72 of the plug connector 60, and the rib 40 enters the annular concave portion 71, so that the short direction of the receptacle connector 20 and the plug connector It is guided so that the short direction of 60 does not shift (see FIG. 8B). In this state, when the receptacle connector 20 is pushed obliquely in the longitudinal direction, the guide groove 45 of the receptacle connector 20 extends along the fitting convex portion (center wall) 72 of the plug connector 60 toward the far side in the longitudinal direction. Move.

リセプタクルコネクタ２０のリブ４０が、プラグコネクタ６０の短手方向側壁の内面に当たると、リセプタクルコネクタ２０のリブ４０がプラグコネクタ６０の逃がし穴８０に嵌まる位置となり、且つ、リセプタクルコネクタ２０の嵌合凹部３２がプラグコネクタ６０の嵌合凸部７２に嵌合する状態となるため、両コネクタが斜めになったまま、リセプタクルコネクタ２０の端とプラグコネクタ６０の端とが部分的に嵌合する状態になる（図８（ｃ）参照）。   When the rib 40 of the receptacle connector 20 hits the inner surface of the side wall in the short direction of the plug connector 60, the rib 40 of the receptacle connector 20 is positioned to fit into the relief hole 80 of the plug connector 60 and the fitting recess of the receptacle connector 20. 32 is fitted to the fitting convex portion 72 of the plug connector 60, so that the end of the receptacle connector 20 and the end of the plug connector 60 are partially fitted while both connectors are inclined. (See FIG. 8C).

両コネクタ６０の端が一部嵌合した状態で、この端を支点となるようにしてリセプタクルコネクタ２０の他端側を押すと、リセプタクルコネクタ２０とプラグコネクタ６０とは完全な嵌合状態になる（図８（ｄ）参照）。   When the other ends of the receptacle connector 20 are pressed with the ends of both the connectors 60 being partly fitted to serve as a fulcrum, the receptacle connector 20 and the plug connector 60 are completely fitted. (See FIG. 8D).

このようにしてリセプタクルコネクタ２０のリブ４０をプラグコネクタ６０の環状凹部７１に入れて、リセプタクルコネクタ２０のガイド溝４５がプラグコネクタ６０の嵌合凸部（中央壁）７２を案内する。すると、リセプタクルコネクタ２０とプラグコネクタ６０とは短手方向に位置決めされる。この短手方向に位置決めされた状態で、リセプタクルコネクタ２０をプラグコネクタ６０の端へと長手方向に滑らせて端まで移動させて押し込むと、殆ど自動的に嵌合を完了させることができる。   In this way, the rib 40 of the receptacle connector 20 is inserted into the annular recess 71 of the plug connector 60, and the guide groove 45 of the receptacle connector 20 guides the fitting convex portion (center wall) 72 of the plug connector 60. Then, the receptacle connector 20 and the plug connector 60 are positioned in the short direction. When the receptacle connector 20 is slid in the longitudinal direction to the end of the plug connector 60 and moved to the end and pushed in with being positioned in the short direction, the fitting can be completed almost automatically.

そして、嵌合された状態では、リセプタクルコネクタ２０のベース３３の上に、プラグコネクタ６０の側壁が載るようになって、両コネクタ２０，６０に無理な力が及ぶことなく、嵌合させることができる。   In the fitted state, the side wall of the plug connector 60 is placed on the base 33 of the receptacle connector 20 so that the two connectors 20 and 60 can be fitted without excessive force. it can.

したがって、両コネクタ２０，６０が小型のものであって位置合わせが困難な場合でも、長手方向及び短手方向の両方の位置合わせを容易に行うことができる。   Therefore, even when both the connectors 20 and 60 are small and it is difficult to align, it is possible to easily align both the longitudinal direction and the short direction.

つぎに、両コネクタ２０，６０のリブ４０と逃がし穴８０とが合わないような方向性を間違えた逆嵌合時の状態を図９により説明する。   Next, a state at the time of reverse fitting in which the directionality in which the rib 40 of the connectors 20 and 60 and the escape hole 80 do not match will be described with reference to FIG.

この逆嵌合時であっても、リセプタクルコネクタ２０のリブ４０はプラグコネクタ６０の環状凹部７１に入り、リセプタクルコネクタ２０のガイド溝４５がプラグコネクタ６０の嵌合凸部（中央壁）７２に案内される状態になるため、図８（ｂ）で示されるのと同じように、リセプタクルコネクタ２０をプラグコネクタ６０の長手方向に滑らせることができる。   Even during this reverse fitting, the rib 40 of the receptacle connector 20 enters the annular recess 71 of the plug connector 60, and the guide groove 45 of the receptacle connector 20 is guided to the fitting convex portion (center wall) 72 of the plug connector 60. Therefore, the receptacle connector 20 can be slid in the longitudinal direction of the plug connector 60 in the same manner as shown in FIG.

ただし、リセプタクルコネクタ２０のリブ４０がプラグコネクタ６０の端に来ると、プラグコネクタ６０の受け面８５に乗り上げて止まる。この状態で、リセプタクルコネクタ２０をプラグコネクタ６０に向けて押し込むと、リブ４０の先端が受け面８５に乗り上げた所を支点として、リセプタクルコネクタ２０が短手方向に傾くという、図９の状態になる。すると、作業者は、嵌合できずに、傾くことから、逆嵌合であることに気付く。   However, when the rib 40 of the receptacle connector 20 comes to the end of the plug connector 60, it rides on the receiving surface 85 of the plug connector 60 and stops. In this state, when the receptacle connector 20 is pushed toward the plug connector 60, the receptacle connector 20 is inclined in the lateral direction with the tip of the rib 40 riding on the receiving surface 85 as a fulcrum. . Then, the operator can not fit, but tilts, and thus notices that it is reverse fitting.

このように、リセプタクルコネクタ２０をプラグコネクタ６０に対して、逆嵌合状態に向かい合わせたとしても、嵌合させることができず、正常時とは異なる動きにより、逆嵌合に直ちに気づき、正しい向きに直すことができる。   As described above, even when the receptacle connector 20 is opposed to the plug connector 60 in the reverse fitting state, the receptacle connector 20 cannot be fitted, and the reverse fitting is immediately noticed by the movement different from the normal state. It can be corrected to the direction.

図１０を参照して本発明の電気コネクタの第１参考例を説明する。図１の第１実施形態では、環状凸部３１の四隅のうち、一方の長手方向側壁３７の両端に位置する２隅（両側の短手方向側壁３８の４つの端うち、一方の長手方向側壁３７に接する２つの端）に、リブ４０が突設されている。第１参考例では、さらに、環状凸部３１の四隅のうち、他方の長手方向側壁３７の両端に位置する２隅（両側の短手方向側壁３８の４つの端うち、他方の長手方向側壁３７に接する２つの端）に、リブ４１が突設されている。そして、リブ４１の長さは、リブ４０の長さより短くなっている。すなわち、ハウジング３０に設けられた四隅のリブ４０，４１は、長手方向の中心線に対して非対称となるようにその長さが異なるように設けられている。また、このリブ４１は、後述する逃がし穴に嵌入し易いように、裁頭４角錘形状の先細りテーパ状に形成されている。また、リブ４１の強度ある大きさを確保する為に、長手方向側壁３７の側に厚みを増やして形成されている。
なお、リブ４０に対して中心線を挟んでリブ４１が設けられることにより、ガイド溝４５の見掛け上の深さが深くなっている。また、ガイド部としてのガイド溝４０は、深さｈ１があることが好ましいが、ｈ１＝０であってもよい。 A first reference example of the electrical connector of the present invention will be described with reference to FIG. In the first embodiment of FIG. 1, of the four corners of the annular protrusion 31, two corners located at both ends of one longitudinal side wall 37 (one longitudinal side wall out of the four ends of the lateral side walls 38 on both sides). The ribs 40 protrude from the two ends that are in contact with 37. In the first reference example , among the four corners of the annular protrusion 31, two corners located at both ends of the other longitudinal side wall 37 (out of the four ends of the lateral side walls 38 on both sides, the other longitudinal side wall 37 is provided. Ribs 41 are provided so as to protrude at two ends in contact with each other. The length of the rib 41 is shorter than the length of the rib 40. That is, the ribs 40 and 41 at the four corners provided in the housing 30 are provided so as to have different lengths so as to be asymmetric with respect to the center line in the longitudinal direction. In addition, the rib 41 is formed in a tapered taper shape having a truncated quadrangular pyramid shape so that the rib 41 can easily be fitted into a later-described escape hole. Further, the rib 41 is formed with an increased thickness on the side of the longitudinal side wall 37 in order to ensure a certain size.
In addition, the apparent depth of the guide groove 45 is deepened by providing the rib 41 with the center line sandwiched from the rib 40. Further, the guide groove 40 as the guide portion preferably has a depth h1, but h1 = 0 may be sufficient.

なお、第１実施形態と同様に、図３において、ハウジング７０の環状凹部７１の環状凹部７１の四隅のうち、一方の長手方向側壁７５の両端に位置する２隅（両側の短手方向側壁７６の４つの端うち、一方の長手方向側壁７５に接する２つの端）に、リブ４０に対応する逃がし穴８０が設けられている。しかし、第２実施形態では、逃がし穴８０が設けられ二つの隅に対向する二つの隅には、第１実施形態の受け面８５に代わり、リブ４１に対応する逃がし穴８１が形成されている。   As in the first embodiment, in FIG. 3, two corners (short-side sidewalls 76 on both sides) located at both ends of one longitudinal side wall 75 among the four corners of the annular recess 71 of the annular recess 71 of the housing 70. Are provided with relief holes 80 corresponding to the ribs 40 at two ends of the four ends. However, in the second embodiment, the relief holes 80 are provided, and the relief holes 81 corresponding to the ribs 41 are formed in the two corners opposed to the two corners, instead of the receiving surface 85 of the first embodiment. .

この第１参考例では、まず、リセプタクルコネクタ２０の環状凸部３１の一方の長手方向側壁３７の両端側に突出するリブ４０，４１の長さの異なる形状によって、リセプタクルコネクタ２０は、長手方向の中心線に対して非対称形状となっている（図１０参照）。そのため、視覚的にも、リセプタクルコネクタ２０の方向性の判断が一層し易くなる。 In the first reference example , first, the receptacle connector 20 is formed in the longitudinal direction by the different shapes of the ribs 40 and 41 protruding from both ends of the one longitudinal side wall 37 of the annular convex portion 31 of the receptacle connector 20. The shape is asymmetric with respect to the center line (see FIG. 10). This makes it easier to visually determine the directionality of the receptacle connector 20.

また、リブ４０，４１が、プラグコネクタの環状凹部の両側の溝に入ることになり、プラグコネクタの嵌合凸部（中央壁）に対するガイド溝４６の案内が一層確実になる。そのため、リセプタクルコネクタ２０をプラグコネクタに対して長手方向に向かって斜めに押すと、リセプタクルコネクタ２０のガイド溝４５がプラグコネクタ６０の嵌合凸部（中央壁）７２に沿って、長手方向奥側に向かってスムーズに移動をする。   Further, the ribs 40 and 41 enter the grooves on both sides of the annular concave portion of the plug connector, and the guide of the guide groove 46 with respect to the fitting convex portion (center wall) of the plug connector is further ensured. Therefore, when the receptacle connector 20 is pushed obliquely in the longitudinal direction with respect to the plug connector, the guide groove 45 of the receptacle connector 20 extends along the fitting convex portion (center wall) 72 of the plug connector 60 in the longitudinal direction rear side. Move smoothly toward.

また、逆嵌合時には、リセプタクルコネクタ２０のリブ４０，４１に対応するプラグコネクタの逃がし穴の深さが合わず、リセプタクルコネクタ２０はプラグコネクタに対して途中で嵌合が止まる半嵌合状態となるため、半嵌合であることが判る。
Also, during the reverse fitting, not meeting the depth of the relief holes of the plug connector corresponding to the rib 40, 41 of the receptacle connector 20, receptacle connector 20 includes a half-fitted state middle fitting stops the plug connector Therefore, it turns out that it is a semi-fitting.

この発明は、以上の実施形態の内容に限定されるものではなく、請求項記載の発明の範囲内において、種々の変更が可能である。   The present invention is not limited to the contents of the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims.

まず、リセプタクルコネクタが一つの側壁を有するものあり、プラグコネクタがこの側壁が挿入される一つの溝を形成する場合である第２参考例を説明する。
この場合、第１のコネクタが、前記第1のコンタクトが少なくとも一列で配設される側壁を有する第１のハウジングを備える。この側壁が嵌合凸部となる。第２のコネクタが、前記側壁が挿入される溝を形成する、一対の壁を有し、前記壁の少なくと一方の長手方向に前記第2コンタクトが列状で配列される第2のハウジングを備える。一対の壁の長手方向の端にも端壁が設けられ、これら壁に囲まれた溝は、嵌合凹部となる。前記第1ハウジングの側壁の長手方向両端に、前記第2ハウジングの溝に入るリブを突設させると共に、前記リブの短手方向の横に、前記壁に当たるガイド部が設けられる。前記第2ハウジングの溝の長手方向両端に、前記リブが嵌まる逃がし穴が設けられる。前記第２ハウジングの両端には、前記ガイド部が嵌まる嵌合部が形成されている。
このような構成の電気コネクタにおいて、第１のハウジングのリブを第２のハウジングの溝に入れ、第１のハウジングのガイド部を第２のハウジングの壁に当てると、両ハウジングの短手方向の位置決めができる。この状態で、第１のハウジングを第２のハウジングに向かって斜めに押し当てるようにして長手方向に移動させる。すると、第１のハウジングのリブが第２のハウジングの逃がし穴に嵌まる位置になって止まり、第１のハウジングと第２のハウジングとの長手方向の位置決めがなされる。更に押し込むと、第１のハウジングの嵌合凸部と第２のハウジングの嵌合凹部との嵌合による正規嵌合となる。 First, the receptacle connector has those having one of the side walls, the plug connector is described a second reference example Ru der case of forming a single groove is the side wall is inserted.
In this case, the first connector includes a first housing having a side wall in which the first contacts are arranged in at least one row. This side wall becomes a fitting convex part. A second connector having a pair of walls forming a groove into which the side wall is inserted, and a second housing in which the second contacts are arranged in a row in at least one longitudinal direction of the walls; Prepare. End walls are also provided at the ends in the longitudinal direction of the pair of walls, and the grooves surrounded by these walls serve as fitting recesses. Ribs that enter the grooves of the second housing protrude from both longitudinal ends of the side walls of the first housing, and guide portions that contact the walls are provided beside the short sides of the ribs. Relief holes into which the ribs are fitted are provided at both longitudinal ends of the groove of the second housing. Fitting portions into which the guide portions are fitted are formed at both ends of the second housing.
In the electrical connector having such a configuration, when the rib of the first housing is put in the groove of the second housing and the guide portion of the first housing is brought into contact with the wall of the second housing, Positioning is possible. In this state, the first housing is moved in the longitudinal direction so as to be obliquely pressed toward the second housing. Then, the rib of the first housing stops at a position where it fits into the escape hole of the second housing, and the first housing and the second housing are positioned in the longitudinal direction. When pushed further, normal fitting is achieved by fitting between the fitting projection of the first housing and the fitting recess of the second housing.

また、第１実施形態において、基板１２，１４が直交する方向に配設されるものであったが、両基板が平行に配設される場合でも本発明を適用できる。
この場合、プラグコネクタの基板に対するベースを嵌合凸部の反対側に設け、コンタクトをリセプタクルコネクタと同様に中心線に対して対称に配設するものに変更すればよい。 Further, Oite to first embodiment type state, but the substrate 12 and 14 was to be arranged perpendicular, the present invention can be applied even if the two substrates are arranged in parallel.
In this case, the base of the plug connector with respect to the substrate may be provided on the opposite side of the fitting convex portion, and the contact may be changed to be disposed symmetrically with respect to the center line as in the case of the receptacle connector.
