Description

この発明は、外部接続コネクタの補強構造及び該補強構造を備える電子機器に係り、特に、薄型の電子機器筐体に適用して好適な外部接続コネクタの補強構造及び該補強構造を備える電子機器に関する。 The present invention relates to an external connection connector reinforcement structure and an electronic device including the reinforcement structure, and more particularly to an external connection connector reinforcement structure suitable for application to a thin electronic device casing and an electronic device including the reinforcement structure. .

携帯電話機等の小型電子機器には、当然ながら、小型で軽量の電子部品や機械部品が実装されることとなる。実装される外部接続コネクタについても、例外ではない。ところで、外部接続コネクタは、機器の外部から、プラグの抜き差しが行われるので、特に、小型なもの程、強度が弱く、コンタクト（ソケット端子）や周囲配線や周囲部品が緩み変形し、断線する虞がある。そこで、従来から、この種の外部接続コネクタは、例えば、特許文献１や特許文献２等に開示されているように、何らかの補強が施されている。 Naturally, small and light electronic parts and mechanical parts are mounted on small electronic devices such as mobile phones. The external connector to be mounted is no exception. By the way, the external connection connector is plugged in and out from the outside of the device. In particular, the smaller the connector, the weaker the strength, and the contact (socket terminal), surrounding wiring, and surrounding parts may loosen and be deformed, resulting in disconnection. There is. Therefore, conventionally, this type of external connection connector has been subjected to some kind of reinforcement as disclosed in, for example, Patent Document 1, Patent Document 2, and the like.

ところで、特許文献１や特許文献２に記載の外部接続コネクタの補強構造は、コネクタ本体内部の主としてコンタクト（ソケット端子）を補強するものであるから、コネクタ本体に、補強タブや補強金具が組み込まれる構成となっている。言い換えれば、補強タブや補強金具も、外部接続コネクタの一部なのである。 By the way, since the reinforcement structure of the external connection connector described in Patent Document 1 or Patent Document 2 mainly reinforces the contact (socket terminal) inside the connector body, a reinforcement tab or a reinforcing metal fitting is incorporated in the connector body. It has a configuration. In other words, the reinforcing tab and the reinforcing metal fitting are also part of the external connection connector.

しかしながら、機器の外部から、プラグの抜き差しによって緩むのは、外部接続コネクタの内部構造だけではない。外部接続コネクタと基板との半田箇所も、プラグの抜き差しによってクラックが生じて断線し、コネクタ破損に至る虞のある箇所である。従来、外部接続コネクタと基板との半田箇所を保護する補強構造として、特許文献３に記載の補強部材が知られている。特許文献３に記載の補強部材には、天板部から上方に高く突出するばね部が一体形成されており、このばね部が、上方のサブフレームに突き当たることによって、上方のサブフレームから、ばね部を介して押圧力を受け、補強部材の固定の一助となる構成となっている。
特開２００１−０３５６０３号公報特開２００３−０９２１５９号公報特開２００２−０７５５５９号公報 However, it is not only the internal structure of the external connection connector that is loosened from the outside of the device by plugging and unplugging. The soldered portion between the external connection connector and the board is also a portion where there is a possibility that a crack may occur due to plugging / unplugging, resulting in breakage of the connector. Conventionally, a reinforcing member described in Patent Document 3 is known as a reinforcing structure for protecting a soldered portion between an external connector and a substrate. The reinforcing member described in Patent Document 3 is integrally formed with a spring portion that protrudes upward from the top plate portion, and the spring portion abuts against the upper subframe, thereby causing the spring from the upper subframe to spring. It is configured to receive a pressing force through the portion and to help fix the reinforcing member.

しかしながら、特許文献３に記載の補強部材には、上記したように、天板部から上方高くにばね部が突出する構成であるため、薄型の電子機器には採用できない、という不具合がある。
加えて、固定フレーム等の下ではなく、例えば、電池パック収納部の開閉蓋の下に実装される外部接続コネクタの補強構造用としては、ばね部を備える上記補強部材は不向きである。さらに、薄型の筐体では、筐体の側壁から、樹脂を庇状に回り込ませて、押さえ機能を持たせることも不可能である。 However, the reinforcing member described in Patent Document 3 has a problem that, as described above, the spring portion protrudes higher upward from the top plate portion, and thus cannot be employed in a thin electronic device.
In addition, the reinforcing member including the spring portion is not suitable for the reinforcing structure of the external connection connector mounted not under the fixed frame or the like but under the opening / closing lid of the battery pack housing portion, for example. Further, in a thin housing, it is impossible to provide a pressing function by causing resin to wrap around from the side wall of the housing.

この発明は、上述の事情に鑑みてなされたもので、プラグの抜き差しから、外部接続コネクタと基板との半田箇所を確実に保護することができ、薄型の電子機器筐体に適用して好適な外部接続コネクタの補強構造及び該補強構造を備える電子機器を提供することを目的としている。 The present invention has been made in view of the above circumstances, and can reliably protect the soldered portion between the external connector and the substrate from plugging / unplugging, and is suitable for application to a thin electronic device casing. It aims at providing the reinforcement structure of an external connection connector, and an electronic device provided with this reinforcement structure.

Each locking hole 22b is provided in the vicinity of the corresponding fitting notch 22a across the resin molded portion of the front end side wall portion 22.

外部接続コネクタ１３は、その差込口１３ａが、前端側壁部２２のコネクタ実装部位に設けられた嵌合用切欠き２２ａに嵌合された状態で、短冊状の基板収納部２１に位置決めされて実装されている。 The external connection connector 13 is positioned and mounted in the strip-shaped board storage portion 21 in a state in which the insertion port 13a is fitted in the fitting notch 22a provided in the connector mounting portion of the front end side wall portion 22. Has been.

この例の補強板金１５は、図６及び図７に示すように、下面に複数の下向き凸部２３、２４、２５を有する概略細長い方形の天板部１５１と、この天板部１５１の後端縁から下方に折曲立設されて、ケース９（電池パック収納部１２）の開閉蓋１１を開けたとき、外部接続コネクタ１３や、コネクタ実装基板１６、スタッキングコネクタ１９等の周辺部品及び周辺配線構造とを外部から見えないように目隠しするための目隠し壁片１５２と、天板部１５１の左右の側端縁から下方に折曲立設されて、左右方向の位置決めのための端部壁片１５３と、天板部１５１の前端縁から下方に折曲立設され、前後方向を位置決めするための前壁片１５４と、天板部１５１の両端部に設けられていて、ケース９（基板収納部２１）の両端部に設けられたネジボス２６にネジ締め２６ａされて固定される固定部１５５とを備え、かつ、前壁片１５４には、外部接続コネクタ１３の差込口１３ａに対応する部位に前側切欠き１５４ａが設けられ、この前側切欠き１５４ａの両端部からそれぞれ前方に突出する前向き突起１５４ｂ、１５４ｂが設けられて箱蓋形状に構成されている。 As shown in FIGS. 6 and 7, the reinforcing sheet metal 15 in this example includes a substantially elongated rectangular top plate portion 151 having a plurality of downward convex portions 23, 24, 25 on the lower surface, and a rear end of the top plate portion 151. When the open / close lid 11 of the case 9 (battery pack storage part 12) is opened downwardly from the edge, peripheral components such as the external connection connector 13, the connector mounting board 16, the stacking connector 19, and the peripheral wiring A blindfold wall piece 152 for concealing the structure so as not to be seen from the outside, and an end wall piece that is bent downward from the left and right side edges of the top plate portion 151 for positioning in the left-right direction 153, bent downward from the front edge of the top plate portion 151, provided on the front wall pieces 154 for positioning in the front-rear direction, and at both ends of the top plate portion 151, and the case 9 (board storage Part 21) are provided at both ends. The front wall piece 154 is provided with a front notch 154a at a portion corresponding to the insertion port 13a of the external connection connector 13, and is fixed to the boss 26 by screwing 26a. Forward-facing protrusions 154b and 154b that protrude forward from both ends of the front notch 154a are provided to form a box lid shape.

ここで、上記天板部１５１に凸設される下向き凸部２３、２４、２５は、具体的には、補強板金１５がケース９に取付け固定された状態で、外部接続コネクタ１３の上面を押付ける左右一対の断面小円状の圧着突起２３、２３と、外部接続コネクタ１３の左右方向の動きを阻止する左右一対の断面小円状の係止突起２４、２４と、外部接続コネクタの後退を阻止する断面短冊状の凸段部２５とからなっている。ここで、右側の係止突起２４と左側の係止突起２４までの隔たりは、右側の圧着突起２３と左側の圧着突起２３までの隔たりよりも長く設定され、右側の係止突起２４は外部接続コネクタ１３の左端部に当接され、左側の係止突起１７は外部接続コネクタ２４の右端部に当接される構成となっている。 Here, the downward projecting portions 23, 24, and 25 projecting from the top plate portion 151 specifically press the upper surface of the external connection connector 13 in a state where the reinforcing sheet metal 15 is attached and fixed to the case 9. A pair of left and right cross-section crimping projections 23 and 23 to be attached, a pair of left and right cross-section locking projections 24 and 24 that prevent the external connection connector 13 from moving in the left-right direction, and the external connection connector are retracted. It consists of a protruding step portion 25 having a strip-shaped cross section to be blocked. Here, the distance between the right locking projection 24 and the left locking projection 24 is set longer than the distance between the right crimping projection 23 and the left crimping projection 23, and the right locking projection 24 is connected to the external connection. It is configured to contact the left end portion of the connector 13, and the left locking projection 17 is configured to contact the right end portion of the external connection connector 24.

上記構成の補強板金１５は、外部接続コネクタ１３及びスタッキングコネクタ１９の上に、端部壁片１５３と前壁片１５４とによって位置決めされて、天板部１５１が被せられ、コネクタ実装部位に設けられた各係止穴２２ｂ、２２ｂに前向き突起１５４ｂ、１５４ｂが嵌合係止され、かつ、目隠し壁片１５２によって、外部接続コネクタ１３とスタッキングコネクタ１９等の外部接続コネクタ１３まわりの配線部とが目隠しされた状態で、固定部１５５がケース９の両端部のネジボス２６にネジ締め２６ａされて固定されている。 The reinforcing sheet metal 15 having the above-described configuration is positioned on the external connection connector 13 and the stacking connector 19 by the end wall piece 153 and the front wall piece 154, and is covered with the top plate portion 151 and provided at the connector mounting portion. Further, the forward projections 154b and 154b are fitted and locked in the respective locking holes 22b and 22b, and the external connection connector 13 and the wiring portion around the external connection connector 13 such as the stacking connector 19 are blinded by the blind wall piece 152. In this state, the fixing portion 155 is fixed to the screw bosses 26 at both ends of the case 9 by screwing 26a.

この固定状態で、補強板金１５の天板部１５１では、断面小円状の圧着突起２３、２３が外部接続コネクタ１３に圧着され、断面小円状の係止突起２４、２４によって、外部接続コネクタ１３の左右方向の動きが係止阻止され、断面短冊状の凸段部２５によって、外部接続コネクタ１３の後退が阻止され、かつ、補強板金１５の前壁片１５４では、前側切欠き１５４ａを挟む左右の前向き突起１５４ｂ、１５４ｂが、外部接続コネクタ１３の差込口１３ａをも挟む態様で、コネクタ実装部位に設けられた係止穴２２ｂ、２２ｂに嵌合係止されている。 In this fixed state, in the top plate portion 151 of the reinforcing sheet metal 15, the crimping protrusions 23, 23 having a small cross section are pressure-bonded to the external connection connector 13, and the locking protrusions 24, 24 having a small cross section have 13 is prevented from moving in the left-right direction, and the protruding step portion 25 having a strip-like cross section prevents the external connection connector 13 from retreating, and the front wall piece 154 of the reinforcing sheet metal 15 sandwiches the front notch 154a. The left and right forward projections 154b and 154b are fitted and locked in locking holes 22b and 22b provided in the connector mounting portion in such a manner as to sandwich the insertion port 13a of the external connection connector 13.

この例の構成によれば、補強板金の固定状態では、補強板金の天板部の各下向き凸部が、外部接続コネクタに圧着又は当接されるので、高さを必要とするばね部も、筐体の側壁からの樹脂の回り込みもなくても、外部接続コネクタのガタツキや緩みが阻止することができるので、薄型の電子機器筐体に好適に適用でき、プラグの抜き差しから、外部接続コネクタと基板との半田箇所を確実に保護することができ、半田箇所のクラックに起因する断線やコネクタ破損を防止できる。 According to the configuration of this example, in the fixed state of the reinforcing sheet metal, each downward convex part of the top plate part of the reinforcing sheet metal is crimped or brought into contact with the external connection connector. Even if the resin does not wrap around from the side wall of the housing, it can be prevented from rattling or loosening of the external connection connector, so it can be suitably applied to thin electronic device housings. The solder location with the substrate can be reliably protected, and disconnection and connector breakage due to cracks in the solder location can be prevented.

加えて、この例の構成のように、外部接続コネクタ１３の差込口１３ａから固定部１５５、１５５までの距離が離れ過ぎている場合でも、左右の前向き突起１５４ｂ、１５４ｂが、補強板金１５の前壁片１５４に設けられていて、外部接続コネクタ１３の差込口１３ａ近傍のコネクタ実装部位に設けられた係止穴２２ｂ、２２ｂに嵌合係止される構成となっているので、プラグの抜き差しによっても、上下方向の撓みやあおりを防止できるので、剛性を確実に維持できる。
また、この例の補強構造１４によれば、開閉蓋１１を開けて、電池パック８を取り除いても、補強板金１５の天板部１５１（図３）と目隠し壁片１５２とで、外部接続コネクタ１３や周辺部品及び周辺配線構造は、外部から見えないように目隠しされているので、美観を保つことができ、機器の破損を防止することもできる。 In addition, even when the distance from the insertion port 13a of the external connection connector 13 to the fixing portions 155 and 155 is too far as in the configuration of this example, the left and right forward projections 154b and 154b are formed on the reinforcing sheet metal 15. Since the front wall piece 154 is configured to be fitted and locked in the locking holes 22b and 22b provided in the connector mounting portion in the vicinity of the insertion port 13a of the external connection connector 13, Even when it is inserted and removed, the vertical deflection and tilt can be prevented, so that the rigidity can be reliably maintained.
Moreover, according to the reinforcing structure 14 of this example, even if the opening / closing lid 11 is opened and the battery pack 8 is removed, the external connection connector is formed by the top plate portion 151 (FIG. 3) of the reinforcing sheet metal 15 and the blind wall piece 152. 13 and the peripheral components and the peripheral wiring structure are concealed so that they cannot be seen from the outside, so that the aesthetics can be maintained and the apparatus can be prevented from being damaged.

図１３は、この発明の第２実施例である外部接続コネクタの補強構造に用いられる補強板金１５Ａの構成を上方（表面側）から見た斜視図、また、図１４は、同補強板金１５Ａの構成を下方（裏面側）から見た斜視図である。
この第２実施例では、前壁片１５４の前向き突起１５４ｂ、１５４ｂとコネクタ実装部位に設けられた係止穴２２ｂ、２２ｂとを廃し、代わりに、第１実施例では、天板部１５１の圧着突起２３、２３が左右一対設けられていたのに対して、左右二対の圧着突起２３、２３、２３ａ、２３ａ設けるようにした点である。この例では、圧着突起２３ａ、２３ａは、図１３及び図１４に示すように、外部接続コネクタ１３の差込口１３ａ近傍に設けられている。この第２実施例の構成によれば、外部接続コネクタ１３の差込口１３ａから固定部１５５、１５５までの距離が離れ過ぎている場合でも、外部接続コネクタ１３の差込口１３ａ近傍の領域が、天板部１５Ａの圧着突起２３ａ、２３ａによって圧着されるので、プラグの抜き差しによっても、上下方向の撓みやあおりを防止できるので、剛性を確実に維持できる。 FIG. 13 is a perspective view of the configuration of the reinforcing sheet metal 15A used in the reinforcing structure of the external connector according to the second embodiment of the present invention as viewed from above (front side), and FIG. 14 is a perspective view of the reinforcing sheet metal 15A. It is the perspective view which looked at the composition from the lower part (back side).
In the second embodiment, the forward projections 154b and 154b of the front wall piece 154 and the locking holes 22b and 22b provided in the connector mounting portion are eliminated. Instead, in the first embodiment, the top plate portion 151 is crimped. A pair of protrusions 23 and 23 are provided on the left and right, whereas two pairs of pressure-bonding protrusions 23, 23, 23 a and 23 a are provided. In this example, the crimping protrusions 23 a and 23 a are provided in the vicinity of the insertion port 13 a of the external connection connector 13 as shown in FIGS. 13 and 14. According to the configuration of the second embodiment, even when the distance from the insertion port 13a of the external connection connector 13 to the fixing portions 155 and 155 is too far, the region in the vicinity of the insertion port 13a of the external connection connector 13 is reduced. Since crimping is performed by the crimping projections 23a and 23a of the top plate portion 15A, vertical bending and tilting can be prevented even when the plug is inserted and removed, so that the rigidity can be reliably maintained.

図１５は、この発明の第３実施例である外部接続コネクタの補強構造を部分的に示す部分断面図である。この例の構成が上記した第１実施例の構成と異なるところは、ネジ締め２６ａ固定に代えて、この例の補強板金１５Ｂの固定部１５５ａには被係止穴２７ａが設けられ、ケース９ａ側に係止爪２７ｂを設けるようにした点である。このようにしても、第１実施例で述べたと略同様の効果を得ることができる。 FIG. 15 is a partial sectional view partially showing a reinforcing structure of an external connection connector according to the third embodiment of the present invention. The configuration of this example is different from the configuration of the first embodiment described above. Instead of fixing the screw 26a, the fixing portion 155a of the reinforcing sheet metal 15B of this example is provided with a locked hole 27a, and the case 9a side. It is a point which provided the latching claw 27b in this. Even in this case, substantially the same effect as described in the first embodiment can be obtained.

以上、この発明の実施例を図面を参照して詳述してきたが、具体的な構成はこの実施例に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があってもこの発明に含まれる。

However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention.
The number of the crimping protrusions and the locking protrusions is not limited to one or two pairs, and can be increased or decreased as necessary. The same applies to the number of convex steps. Instead of the convex step portion, a projection having a small circular cross section may be used.
