Description

本発明の実施形態は、基板用コネクタに関する。 Embodiments of the present invention relate to a board connector.

従来、例えばマザーボードに設けられ、拡張基板の端部を挿入可能な基板用コネクタが知られている。基板用コネクタは、挿入部を有するコネクタ本体と、コネクタ本体の両側から互いに平行に延出された一対の保持アームと、各保持アームの延出端（先端）に設けられた凸部と、を有している。一方、拡張基板の両側には、保持アームの凸部が係合可能な凹部が設けられている。 2. Description of the Related Art Conventionally, there is known a board connector that is provided on, for example, a mother board and into which an end of an expansion board can be inserted. The board connector includes a connector main body having an insertion portion, a pair of holding arms extending parallel to each other from both sides of the connector main body, and a convex portion provided at an extending end (tip) of each holding arm. Have On the other hand, on both sides of the extension board, there are provided concave portions with which the convex portions of the holding arm can be engaged.

ここで、拡張基板の端部をコネクタ本体の挿入部に挿入する。そうすると、凸部が凹部に係合する。このとき、凸部と凹部との係合状態は、保持アーム自体の弾性力によって維持される。かくして、拡張基板は、一対の保持アームによって、その両側を挟むように保持され、これにより、拡張基板と基板用コネクタとが電気的に接続される。 Here, the end portion of the extension board is inserted into the insertion portion of the connector body. Then, the convex portion engages with the concave portion. At this time, the engagement state between the convex portion and the concave portion is maintained by the elastic force of the holding arm itself. Thus, the extension board is held by the pair of holding arms so as to sandwich the both sides thereof, whereby the extension board and the board connector are electrically connected.

特開２０１０−２２５４６６号公報JP, 2010-225466, A 特許第５４２９３０８号公報Japanese Patent No. 5429308 特許第３７３０１１６号公報Japanese Patent No. 3730116

ところで、上記した従来の基板用コネクタでは、平板状の拡張基板の両側が一対の保持アームによって挟持された状態にある。このような状態によれば、例えば、基板用コネクタや拡張基板に作用した外圧ないし外部振動の大きさの程度によっては、凸部と凹部との係合状態が解除され、その結果、基板用コネクタから拡張基板が抜けたり、更には、脱落したりしてしまう虞がある。 By the way, in the above-mentioned conventional board connector, both sides of the flat board-like extension board are held by the pair of holding arms. According to such a state, for example, depending on the magnitude of external pressure or external vibration applied to the board connector or the extension board, the engagement state between the convex portion and the concave portion is released, and as a result, the board connector is released. There is a risk that the expansion board may come off from the machine, or even fall off.

本発明の目的は、一対の保持アームで両側が挟持された拡張基板の抜け（脱落）防止を図る基板用コネクタを提供することにある。 An object of the present invention is to provide a board connector that prevents the extension board, which is sandwiched on both sides by a pair of holding arms, from coming off (falling off).

実施形態によれば、基板用コネクタは、コネクタ本体と、抜け防止機構と、を有する。抜け防止機構は、基板の端部をコネクタ本体の挿入部に挿入した状態において、基板の嵌合部に嵌り合うことで、挿入部からの基板の抜け防止を図る。 According to the embodiment, the board connector includes a connector body and a disconnection prevention mechanism. The removal prevention mechanism prevents the board from coming off from the insertion section by fitting the board end into the fitting section of the board when the end section of the board is inserted into the insertion section of the connector body.

「一実施形態の構成」
図１は、一実施形態に係る基板用コネクタ１（以下、コネクタと言う）の配置構成図である。図１では一例として、コネクタ１は、マザーボード２（電子回路基板）に設けられている。マザーボード２は、デスクトップパソコンやノートパソコン、タブレット端末に内蔵され、例えば、電源、ＣＰＵ、メモリなどの電子部品を搭載させることが可能に構成されている。コネクタ１は、マザーボード２と、他の基板３（以下、拡張基板と言う）とを電気的に接続させることが可能に構成されている。 "Configuration of one embodiment"
FIG. 1 is a layout configuration diagram of a board connector 1 (hereinafter, referred to as a connector) according to an embodiment. In FIG. 1, as an example, the connector 1 is provided on the motherboard 2 (electronic circuit board). The motherboard 2 is built in a desktop personal computer, a notebook computer, or a tablet terminal, and is configured so that electronic components such as a power supply, a CPU, and a memory can be mounted. The connector 1 is configured to be capable of electrically connecting the mother board 2 and another board 3 (hereinafter referred to as an expansion board).

なお、拡張基板３は、平板状の矩形を成し、表面３ａ及び裏面３ｂを有している。拡張基板３は、コネクタ１に挿入させることが可能な端部３ｐと、当該端部３ｐを挟んで拡張基板３の両側に設けられた側面３ｓとを有している。拡張基板３の両側面３ｓには、後述する凸部６が係合可能な凹部４が予め設けられている。凹部４は、例えば、側面３ｓの一部を矩形状に窪ませて構成されている。 The extension board 3 is in the shape of a flat plate and has a front surface 3a and a back surface 3b. The extension board 3 has an end portion 3p that can be inserted into the connector 1 and side surfaces 3s provided on both sides of the extension board 3 with the end portion 3p interposed therebetween. On both side surfaces 3s of the extension substrate 3, a concave portion 4 into which a convex portion 6 described later can be engaged is provided in advance. The concave portion 4 is formed by, for example, denting a part of the side surface 3s in a rectangular shape.

図１に示すように、コネクタ１は、コネクタ本体１ｐと、保持アーム５と、凸部６と、を有している。コネクタ本体１ｐは、マザーボード２に対して電気的に連結され、拡張基板３の端部３ｐを挿入可能な挿入部１ｓを有している。保持アーム５は、コネクタ本体１ｐの両側から互いに平行に延出されている。凸部６は、各保持アーム５の延出端に設けられ、拡張基板３の端部３ｐをコネクタ本体１ｐの挿入部１ｓに挿入する際に凹部４に係合する。図１の例において、一対の保持アーム５は、マザーボード２と平行に延出されている。この場合、拡張基板３は、コネクタ本体１ｐ（挿入部１ｓ）に対して傾斜させて挿入させる。 As shown in FIG. 1, the connector 1 has a connector body 1p, a holding arm 5, and a convex portion 6. The connector body 1p is electrically connected to the mother board 2 and has an insertion portion 1s into which the end portion 3p of the extension board 3 can be inserted. The holding arms 5 extend parallel to each other from both sides of the connector body 1p. The convex portion 6 is provided at the extended end of each holding arm 5, and engages with the concave portion 4 when the end portion 3p of the extension board 3 is inserted into the insertion portion 1s of the connector body 1p. In the example of FIG. 1, the pair of holding arms 5 extend in parallel with the motherboard 2. In this case, the extension board 3 is inserted while being inclined with respect to the connector body 1p (insertion portion 1s).

図２は、拡張基板３の保持状態図である。図２では一例として、拡張基板３は、マザーボード２と平行な位置関係を有してコネクタ１に保持されている。ここで、拡張基板３の保持プロセスによれば、先ず、拡張基板３をマザーボード２に対して傾斜させつつ、当該拡張基板３の端部３ｐをコネクタ本体１ｐ（挿入部１ｓ）に挿入する（図１参照）。 FIG. 2 is a holding state diagram of the extension board 3. As an example in FIG. 2, the extension board 3 is held by the connector 1 in a positional relationship parallel to the mother board 2. Here, according to the holding process of the extension board 3, first, the end portion 3p of the extension board 3 is inserted into the connector body 1p (insertion portion 1s) while inclining the extension board 3 with respect to the mother board 2 (FIG. 1).

次に、マザーボード２と平行となるように、拡張基板３を変位させる。同時に、一対の保持アーム５を弾性変形させて、当該保持アーム５の延出端（凸部６）を互いに離間させる。そして、拡張基板３がマザーボード２と平行な位置関係となったとき、保持アーム５の弾性変形を解除する。 Next, the extension board 3 is displaced so as to be parallel to the mother board 2. At the same time, the pair of holding arms 5 is elastically deformed to separate the extended ends (projections 6) of the holding arms 5 from each other. Then, when the extension board 3 is placed in a positional relationship parallel to the mother board 2, the elastic deformation of the holding arm 5 is released.

そうすると、図２に示すように、保持アーム５は、自身の復元力によって初期形状に弾性変形する。このとき、保持アーム５の凸部６が、拡張基板３の凹部４に係合する。図２の例において、凸部６と凹部４との係合状態は、凹部４に係合した凸部６の一部（例えば、先端部分６ｐ）が拡張基板３の表面３ａに圧接する。 Then, as shown in FIG. 2, the holding arm 5 is elastically deformed into the initial shape by its restoring force. At this time, the convex portion 6 of the holding arm 5 engages with the concave portion 4 of the extension board 3. In the example shown in FIG. 2, in the engagement state between the convex portion 6 and the concave portion 4, a part (for example, the tip portion 6p) of the convex portion 6 engaged with the concave portion 4 is in pressure contact with the surface 3a of the expansion substrate 3.

このような状態において、拡張基板３は、一対の保持アーム５によって、その両側を挟むように保持される。これにより、拡張基板３は、マザーボード２から起立（傾斜）する方向（図１参照）への変位動作が抑制される。この結果、拡張基板３は、マザーボード２と平行な位置関係を有してコネクタ１に保持される。 In such a state, the extension board 3 is held by the pair of holding arms 5 so as to sandwich both sides thereof. As a result, the displacement operation of the extension board 3 in the direction of standing (tilting) from the mother board 2 (see FIG. 1) is suppressed. As a result, the extension board 3 is held by the connector 1 in a positional relationship parallel to the mother board 2.

ところで、上記した凸部６と凹部４との係合状態については、コネクタ１や拡張基板３に作用した外圧ないし外部振動の大きさの程度によって、その係合状態が解除されてしまう虞がある。例えば、拡張基板３が、マザーボード２と平行な方向に、コネクタ１から抜けたり、脱落したりしてしまう場合が想定される。そこで、コネクタ１には、一対の保持アーム５で両側が挟持された拡張基板３の抜け（脱落）防止を図る抜け防止機構７（図３参照）が設けられている。 By the way, the engagement state between the convex portion 6 and the concave portion 4 may be released depending on the magnitude of external pressure or external vibration acting on the connector 1 or the extension substrate 3. .. For example, it is assumed that the extension board 3 may come off or come off from the connector 1 in a direction parallel to the mother board 2. Therefore, the connector 1 is provided with a detachment prevention mechanism 7 (see FIG. 3) for preventing the extension substrate 3 whose both sides are sandwiched by the pair of holding arms 5 from detaching (disengaging).

図３は、抜け防止機構７の構成図である。抜け防止機構７は、拡張基板３に予め設けられた嵌合部３ｅ（図１、図２、図４参照）を利用している。嵌合部３ｅは、拡張基板３の表面３ａから裏面３ｂに亘って構成されている。図１、図２、図４では一例として、嵌合部３ｅは、拡張基板３の表面３ａから裏面３ｂを貫通させた貫通孔３ｅとして構成されている。なお、嵌合部（貫通孔）３ｅの形状や大きさは、例えば、拡張基板３の種類やサイズに応じて設定されるため、ここでは特に限定しない。嵌合部（貫通孔）３ｅの形状としては、例えば、円形、三角形、矩形など各種形状が想定される。 FIG. 3 is a configuration diagram of the removal prevention mechanism 7. The slip-out prevention mechanism 7 uses a fitting portion 3e (see FIGS. 1, 2, and 4) provided in advance on the extension board 3. The fitting portion 3e is formed from the front surface 3a to the back surface 3b of the extension board 3. As an example in FIG. 1, FIG. 2, and FIG. 4, the fitting portion 3e is configured as a through hole 3e that penetrates the front surface 3a and the back surface 3b of the extension board 3. The shape and size of the fitting portion (through hole) 3e are set according to, for example, the type and size of the expansion board 3, and are not particularly limited here. As the shape of the fitting portion (through hole) 3e, various shapes such as a circle, a triangle, and a rectangle are assumed, for example.

図３に示すように、抜け防止機構７は、抜け止め本体７ｐと、嵌入構造８と、を有している。抜け止め本体７ｐの材質としては、例えば、金属材料、樹脂材料のいずれも適用可能である。抜け止め本体７ｐと嵌入構造８とは、互いに一体的に成形してもよいし、或いは、別体で成形し、抜け止め本体７ｐに嵌入構造８を後付けしてもよい。 As shown in FIG. 3, the disengagement prevention mechanism 7 includes a disengagement prevention body 7p and a fitting structure 8. As the material of the retaining body 7p, for example, either a metal material or a resin material can be applied. The retaining body 7p and the fitting structure 8 may be integrally molded with each other, or may be molded separately, and the retaining structure 7p may be retrofitted to the retaining body 7p.

抜け止め本体７ｐは、弾性を有する片持ち梁状を成している。抜け止め本体７ｐは、基端がコネクタ１に支持され、先端が自由端となっている。図３の例において、抜け止め本体７ｐは、一対の保持アーム５の相互間に配置されている。この場合、抜け止め本体７ｐは、基端が保持アーム５の対向面５ｓに支持され、基端から先端に亘って保持アーム５（対向面５ｓ）と平行に延在されている。対向面５ｓとは、平行に延出された一対の保持アーム５のうち、互いに対向した位置関係にある内側面５ｓを指す。 The retaining body 7p has a cantilever shape having elasticity. The retainer body 7p has a base end supported by the connector 1 and a free end. In the example of FIG. 3, the retaining body 7p is arranged between the pair of holding arms 5. In this case, the retaining body 7p has its base end supported by the facing surface 5s of the holding arm 5 and extends in parallel with the holding arm 5 (opposing surface 5s) from the base end to the tip. The opposing surface 5s refers to the inner surface 5s of the pair of holding arms 5 extending in parallel and having a positional relationship of facing each other.

嵌入構造８は、抜け止め本体７ｐの先端（自由端）に設けられている。嵌入構造８は、拡張基板３の嵌合部（貫通孔）３ｅに嵌り込み可能な輪郭を有している。嵌入構造８は、マザーボード２（図１参照）から離間する方向に向けて、抜け止め本体７ｐの先端（自由端）から連続的に立ち上げられている。ここで、嵌合部（貫通孔）３ｅの形状が円形の場合、嵌入構造８は、当該円形の嵌合部（貫通孔）３ｅに嵌り込み可能な輪郭（例えば、円筒状、円柱状）を有している。この場合、円筒（円柱）状の嵌入構造８の直径は、円形の嵌合部（貫通孔）３ｅの内径と同一或いは若干小さく設定することが好ましい。 The fitting structure 8 is provided at the tip (free end) of the retaining body 7p. The fitting structure 8 has a contour that can be fitted into the fitting portion (through hole) 3e of the extension board 3. The fitting structure 8 is continuously erected from the tip (free end) of the retaining body 7p in a direction away from the motherboard 2 (see FIG. 1). Here, when the shape of the fitting portion (through hole) 3e is circular, the fitting structure 8 has a contour (for example, a cylindrical shape or a cylindrical shape) that can be fitted into the circular fitting portion (through hole) 3e. Have In this case, the diameter of the cylindrical (cylindrical) fitting structure 8 is preferably set to be the same as or slightly smaller than the inner diameter of the circular fitting portion (through hole) 3e.

図４は、抜け防止機構７（抜け止め本体７ｐ、嵌入構造８）と、嵌合部（貫通孔）３ｅとの係合プロセスを示す模式図である。図４に示すように、拡張基板３をマザーボード２（図１参照）に対して傾斜させつつ、当該拡張基板３の端部３ｐをコネクタ本体１ｐ（挿入部１ｓ）に挿入する。かかる挿入に際し、嵌入構造８は、嵌合部（貫通孔）３ｅに嵌り込み可能に位置付けられる。 FIG. 4 is a schematic diagram showing an engagement process of the detachment prevention mechanism 7 (the detachment prevention body 7p, the fitting structure 8) and the fitting portion (through hole) 3e. As shown in FIG. 4, the end portion 3p of the extension board 3 is inserted into the connector body 1p (insertion portion 1s) while the extension board 3 is inclined with respect to the mother board 2 (see FIG. 1). At the time of such insertion, the fitting structure 8 is positioned so that it can be fitted into the fitting portion (through hole) 3e.

次に、マザーボード２と平行となるように、拡張基板３を変位させると共に、保持アーム５の凸部６を拡張基板３の凹部４に係合させる。このとき、拡張基板３は、その両側が一対の保持アーム５で挟持される。同時に、嵌入構造８が、嵌合部（貫通孔）３ｅに嵌り込む（図５参照）。 Next, the extension board 3 is displaced so as to be parallel to the mother board 2, and the projection 6 of the holding arm 5 is engaged with the recess 4 of the extension board 3. At this time, the extension board 3 is held by the pair of holding arms 5 on both sides thereof. At the same time, the fitting structure 8 is fitted into the fitting portion (through hole) 3e (see FIG. 5).

図５は、抜け防止機構７の嵌入構造８と、拡張基板３の嵌合部（貫通孔）３ｅとが嵌り合った状態を示す模式図である。図５に示すように、嵌合状態において、円筒（円柱）状の嵌入構造８が、円形の嵌合部（貫通孔）３ｅに隙間無く接触する。これにより、コネクタ本体１ｐ（挿入部１ｓ）からの拡張基板３の抜け防止が図られる。この結果、拡張基板３の端部３ｐと、コネクタ本体１ｐ（挿入部１ｓ）の金属端子９との接続状態が一定に維持される。なお、図５の例において、コネクタ本体１ｐ（挿入部１ｓ）に挿入された拡張基板３の端部３ｐは、コネクタ本体１ｐ（挿入部１ｓ）に内蔵された付勢バネ１０によって、常に、金属端子９に向けて押圧される。 FIG. 5 is a schematic diagram showing a state in which the fitting structure 8 of the removal prevention mechanism 7 and the fitting portion (through hole) 3e of the extension board 3 are fitted to each other. As shown in FIG. 5, in the fitted state, the cylindrical (cylindrical) fitting structure 8 comes into contact with the circular fitting portion (through hole) 3e without a gap. This prevents the extension board 3 from coming off from the connector body 1p (insertion portion 1s). As a result, the connection state between the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (insertion portion 1s) is maintained constant. In the example of FIG. 5, the end portion 3p of the extension board 3 inserted into the connector body 1p (insertion portion 1s) is always made of metal by the biasing spring 10 incorporated in the connector body 1p (insertion portion 1s). It is pressed toward the terminal 9.

「一実施形態の作用効果」
以上、本実施形態によれば、抜け防止機構７を備えたことで、保持アーム５で両側が挟持された拡張基板３の抜け（脱落）防止を図ることができる。この場合、コネクタ１や拡張基板３に外圧ないし外部振動が作用しても、保持アーム５の凸部６ｐと拡張基板３の凹部４との係合状態が一定に維持される。これにより、拡張基板３の端部３ｐと、コネクタ本体１ｐ（挿入部１ｓ）の金属端子９との接続状態が一定に維持される。この結果、コネクタ１と拡張基板３との電気的な接続状態を長期に亘って一定に維持することができる。 "Operation and effect of one embodiment"
As described above, according to the present embodiment, since the removal prevention mechanism 7 is provided, it is possible to prevent the extension board 3 whose both sides are held by the holding arm 5 from coming off (falling off). In this case, even if external pressure or external vibration acts on the connector 1 and the extension board 3, the engagement state between the protrusion 6p of the holding arm 5 and the recess 4 of the extension board 3 is maintained constant. As a result, the connection state between the end portion 3p of the extension board 3 and the metal terminal 9 of the connector body 1p (insertion portion 1s) is maintained constant.
