【発明の属する技術分野】
本発明は、２枚のプリント基板等を接続するコネクタの嵌合状態を保持するロック機構に関する。
【０００２】
【従来の技術】
第１の従来のコネクタの要点について図８を参照して説明する。このコネクタは、特開平１１−７４０２４号公報に記載されている。
【０００３】
図８は、レセプタクルコネクタ２１とプラグコネクタ３１とが嵌合した状態を示す。
【０００４】
レセプタクルコネクタ２１は、インシュレータ２２と、インシュレータ２２の両側に配設されて保持される多数対のコンタクト２３とから構成される。各コンタクト２３は、逆Ｕ字形状の保持部２３Ａと、保持部２３Ａの一端に連続する横Ｌ字形状のばね部２３Ｂと、ばね部２３Ｂに連続する円弧形状の接点部２３Ｃと、保持部２３Ａの他端に連続する表面実装部２３Ｄとから一体に構成される。
【０００５】
プラグコネクタ３１は、インシュレータ３２と、インシュレータ３２の両側に配設されて保持される多数対の逆Ｌ字形状のコンタクト３３とから構成される。
【０００６】
図８の状態では、各コンタクト３３は、各コンタクト２３の接点部２３Ｃと圧接し、プラグコネクタ３１とレセプタクルコネクタ２１とは、接続する。
【０００７】
第２の従来のコネクタの要点について図９を参照して説明する。このコネクタは、特開２００１−５７２７３号公報に記載されている。
【０００８】
図９は、レセプタクルコネクタ４１とプラグコネクタ５１とが嵌合する前の状態を示す。
【０００９】
レセプタクルコネクタ４１は、略直方体形状のインシュレータ４２と、インシュレータ４２の長手方向の両側に配設されて保持される多数対のコンタクト４３と、インシュレータ４２の両側端付近に保持される各ロック部材４４とから構成される。各ロック部材４４は、両側先端の各ロック部４４Ａと、各ロック部４４Ａに連続する各ばね部４４Ｂと、両ばね部４４Ｂを連結する連結部４４Ｃとから一体に構成される。
【００１０】
プラグコネクタ５１は、略直方体形状のインシュレータ５２と、インシュレータ５２の長手方向の両側に配設されて保持される多数対のコンタクト５３と、インシュレータ５２の四隅付近に保持される各被ロック部材５４とから構成される。
【００１１】
プラグコネクタ５１の嵌合部５２Ａをレセプタクルコネクタ４１の嵌合部４２Ａに矢印方向に挿入すると、プラグコネクタ５１は、レセプタクルコネクタ４１と嵌合する。このとき、各コンタクト５３は、各コンタクト４３と接触し、各ロック部材４４のロック部４４Ａは、各被ロック部材５４をロックする。したがって、プラグコネクタ５１は、レセプタクルコネクタ４１からの離脱を防止される。
【００１２】
【発明が解決しようとする課題】
第１の従来のコネクタにおいては、対向する一対のコンタクト２３の一方の表面実装部２３Ｄから他方の表面実装部２３Ｄまでのサイズが大きい。また、コネクタの長手方向（コンタクトのピッチ方向）にロック部が形成されているので、長手方向のサイズが大型にならざるを得ない。
【００１３】
第２の従来のコネクタは、嵌合状態を保持するロック機構（各ロック部材４４と各被ロック部材５４）を有するが、ホールドダウンを有しない。したがって、ホールドダウンをコネクタに設置する場合には、インシュレータ４２の長手方向のサイズが大型にならざるを得ない。
【００１４】
そこで、本発明は、前記両従来のコネクタの欠点を改良し、嵌合状態を保持するロック機構及びホールドダウンを有し、しかも、小型のコネクタを提供しようとするものである。
【００１５】
【課題を解決するための手段】
本発明は、前記課題を解決するため、次の手段を採用する。
【００１６】
１．一方のコネクタと他方のコネクタとが嵌合離脱するコネクタにおいて、前記一方のコネクタは、インシュレータと、前記インシュレータの両側に対向して保持される複数対のコンタクトと、前記インシュレータの両側の端部付近に対向して保持される各一対の略平板状の嵌合ロック兼固定用ホールドダウンとから構成され、前記各嵌合ロック兼固定用ホールドダウンは、弾性変形可能なロック部を有し、前記ロック部には、突起が形成され、前記他方のコネクタは、インシュレータと、当該インシュレータの両側に対向して保持される複数対のコンタクトと、当該インシュレータの両側の端部付近に対向して保持される各少なくとも一対の嵌合被ロック兼固定用ホールドダウンとから構成され、当該各コンタクトと前記各嵌合被ロック兼固定用ホールドダウンとは同一部品であり、前記各嵌合被ロック兼固定用ホールドダウンは、当該インシュレータに保持される保持部を有し、前記保持部の先端には、被ロック受部が形成され、１つの前記嵌合ロック兼固定用ホールドダウンに複数の前記嵌合被ロック兼固定用ホールドダウンが対応し、前記一方のコネクタと前記他方のコネクタとが嵌合したとき、前記突起が前記被ロック受部に係合するコネクタのロック機構。
【００１７】
２．前記各嵌合ロック兼固定用ホールドダウンのロック部と前記インシュレータに保持される保持部とは、略Ｕ字形状に構成され、前記各嵌合被ロック兼固定用ホールドダウンの保持部は、略Ｊ字形状に構成され、当該インシュレータと一体成形される前記１記載のコネクタのロック機構。
【００１８】
【発明の実施の形態】
本発明の一実施の形態例の基板対基板間接続多極コネクタについて図１〜図７を参照して説明する。
【００１９】
まず、レセプタクルコネクタ１について図１と図２を参照して説明する。レセプタクルコネクタ１は、略直方体形状のインシュレータ２と、インシュレータ２の幅方向の両側に対向して保持される２０対のコンタクト３と、インシュレータ２の長手方向（コンタクトのピッチ方向）の両側の端部付近に対向して保持される各一対（合計４本）の嵌合ロック兼固定用ホールドダウン（補強金具）４とから構成される。
【００２０】
各コンタクト３は、インシュレータ２の隙間２Ａに挟持される保持部３Ａと、保持部３Ａから一方側に略Ｖ字形状に延出し、嵌合時にプラグコネクタ（後述する。）のコンタクトと接触する弾性変形可能な接触部３Ｂと、保持部３Ａから他方側に延出し、プリント基板６（図７参照）に半田付けにより固定される端子部３Ｃとから一体に構成される。
【００２１】
各嵌合ロック兼固定用ホールドダウン４は、略平板状に形成され、インシュレータ２の隙間２Ｂに挟持される保持部４Ａと、保持部４Ａから一方側に略Ｌ字形状に延出し、嵌合時にプラグコネクタの各嵌合被ロック兼固定用ホールドダウンの保持部に係合する弾性変形可能なロック部４Ｂと、保持部４Ａから他方側に延出し、プリント基板６に半田付けにより固定される固定部４Ｃとから一体に構成される。なお、保持部４Ａとロック部４Ｂは、略Ｕ字形状に構成される。各固定部４Ｃの下部４Ｃ１は、本発明ではコンタクト３の端子部３Ｃと同様な形状に構成したが、設計変更により、図１（ｅ）に示されるように、インシュレータ２の長手方向に平行になるように直角に折曲して略Ｌ字形状に構成してもよい。なお、各コンタクト３と各嵌合ロック兼固定用ホールドダウン４は、インシュレータ２の下方から圧入される。
【００２２】
次に、プラグコネクタ１１について図３と図４を参照して説明する。プラグコネクタ１１は、略直方体形状のインシュレータ１２と、インシュレータ１２の幅方向の両側に対向して保持される２０対のコンタクト１３と、インシュレータ１２の長手方向の両側の端部付近に対向して保持される各二対（合計８本）の嵌合被ロック兼固定用ホールドダウン（補強金具）１４とから構成される。各コンタクト１３と各嵌合被ロック兼固定用ホールドダウン１４とを同一部品に構成すると、コストが安価になる。
【００２３】
各コンタクト１３は、インシュレータ１２を抱持する略Ｊ字形状の保持部１３Ａと、保持部１３Ａに連続し、プリント基板１６（図７参照）に半田付けにより固定される端子部１３Ｂとから一体に構成される。各コンタクト１３は、インシュレータ１２と一体成形される。インシュレータ１２には、一体成形時に各コンタクト１３を押圧するための穴１２Ａが設けられている。
【００２４】
各嵌合被ロック兼固定用ホールドダウン１４は、インシュレータ１２を抱持する略Ｊ字形状の保持部１４Ａと、保持部１４Ａに連続し、プリント基板に半田付けにより固定される固定部１４Ｂとから一体に構成される。各嵌合被ロック兼固定用ホールドダウン１４は、インシュレータ１２と一体成形される。
【００２５】
プラグコネクタ１１をレセプタクルコネクタ１に嵌合するときのロック過程について図５を参照して説明する。図５（ａ）は嵌合途中の状態、図５（ｂ）は嵌合完了の状態を、それぞれ示す。図５（ａ）の状態では、レセプタクルコネクタ１の各１本の嵌合ロック兼固定用ホールドダウン４のロック部４Ｂは、プラグコネクタ１１の各２本の嵌合被ロック兼固定用ホールドダウン１４の保持部１４Ａにより外側に弾性変形させられる。続いて、各保持部１４Ａの先端に形成された被ロック受部１４Ａ１が各ロック部４Ｂに形成された突起４Ｂ１を通過すると、図５（ｂ）の状態に至り、突起４Ｂ１が被ロック受部１４Ａ１に係合するので、プラグコネクタ１１はレセプタクルコネクタ１にロックされる。本実施の形態例では、１本の嵌合ロック兼固定用ホールドダウン４に２本の嵌合被ロック兼固定用ホールドダウン１４が対応するので、後者の負荷は半減する。
【００２６】
このとき、図４（ａ）に示されるプラグコネクタ１１の各コンタクト１３の接触面１３Ａ１は、図２（ａ）に示されるレセプタクルコネクタ１の各コンタクト３の接触部３Ｂに圧接する。したがって、プラグコネクタ１１は、レセプタクルコネクタ１と接続する。
【００２７】
本発明の一実施の形態例におけるロック機構を有するレセプタクルコネクタ１の占有面積は、図６（ａ）に示されるようにＬ１×Ｌ２である。これに対して、ロック機構を有しないレセプタクルコネクタ２０の占有面積も、図６（ｂ）に示されるようにＬ１×Ｌ２であり、両占有面積は、等しい。
【００２８】
また、本発明の一実施の形態例のロック機構を有するコネクタでは、図７に示されるように、プラグコネクタ１１は、コネクタの幅方向に矢印のように回転し難く、また、幅方向に直交する長手方向にも同様に回転し難い。したがって、プラグコネクタ１１とレセプタクルコネクタ１とは、安定して接続する。
【００２９】
本実施の形態例におけるプラグコネクタ１１には、インシュレータ１２の長手方向の両側の端部付近に、各二対の嵌合被ロック兼固定用ホールドダウン１４が対向して保持されるが、各一対又は各三対以上に設計変更することができる。
【００３０】
【発明の効果】
以上の説明から明らかなように、本発明によれば、次の効果が奏される。
【００３１】
１．嵌合ロック部材をホールドダウンが兼ね、かつ、嵌合被ロック部材をホールドダウンが兼ねるので、コネクタの小型化を図ることができ、また、部品点数が減少する。
【００３２】
２．コネクタの４箇所にそれぞれ独立したロック機構が設置されているので、コネクタは一方向とこの一方向に直交する方向に回転し難い。したがって、コネクタは、安定して接続する。
【００３３】
３．嵌合ロック兼固定用ホールドダウンのロック部とインシュレータに保持される保持部とは、略Ｕ字形状に構成され、かつ、嵌合被ロック兼固定用ホールドダウンの保持部は、略Ｊ字形状に構成されてインシュレータを抱持するので、コネクタの構造が、簡素で、また、コンパクトで、更に、堅牢である。

[0027]
The occupied area of the receptacle connector 1 having the lock mechanism according to the embodiment of the present invention is L 1 × L 2 as shown in FIG. On the other hand, the occupied area of the receptacle connector 20 having no lock mechanism is also L 1 × L 2 as shown in FIG. 6B, and both occupied areas are equal.
[0028]
In the connector having the lock mechanism according to the embodiment of the present invention, as shown in FIG. 7, the plug connector 11 is hard to rotate in the width direction of the connector as indicated by an arrow, and is orthogonal to the width direction. Similarly, it is difficult to rotate in the longitudinal direction. Therefore, the plug connector 11 and the receptacle connector 1 are stably connected.
[0029]
In the plug connector 11 in the present embodiment, two pairs of the locked / fixed holddowns 14 are held opposite to each other near the ends on both sides of the insulator 12 in the longitudinal direction. Alternatively, the design can be changed to three or more pairs.
[0030]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.
[0031]
1. Since the fitting lock member also serves as a hold-down and the fitted locked member also serves as a hold-down, the size of the connector can be reduced, and the number of components can be reduced.
[0032]
2. Since independent locking mechanisms are provided at four locations of the connector, it is difficult for the connector to rotate in one direction and a direction orthogonal to the one direction. Therefore, the connector is connected stably.
[0033]
3. The lock portion of the fitting lock / fixing holddown and the holding portion held by the insulator are formed in a substantially U-shape, and the holding portion of the fitting locked / fixing holddown is a substantially J-shape. Therefore, the structure of the connector is simple, compact, and robust.
