And an elastic portion 52 that comes into contact with each other. The terminal surface 51 is formed in a thin rectangular plate shape, and the upper end portion of the terminal surface 51 is bent once so as to be substantially parallel, and then drawn upward toward the inside of the operation unit side body 2. An elastic part 52 is formed. In addition, the front-end | tip part 521 of the elastic part 52 has faced a little downward. A plurality of such charging terminals 5 are arranged at predetermined intervals and are held by a holder 6.

ホルダ６は、互いに所定間隔を隔てて配置された複数の充電端子５の各端子面５１の上下左右の縁部５１１を覆うホルダ本体６１と、ホルダ本体６１の背面から操作部側筐体２の内部に向けて延在し、各充電端子５の弾性部５２間に介在される複数のリブ６２と、を備えている。

そして、これら各凸部６１４の両脇（弾性部５２の両脇）にリブ６２が設けられている。リブ６２は、ホルダ本体６１の背面に対して略垂直に延在し、弾性部５２と略同じ長さとなっている。 The holder 6 includes a holder main body 61 that covers the upper, lower, left, and right edges 511 of the terminal surfaces 51 of the plurality of charging terminals 5 that are arranged at a predetermined interval from each other; A plurality of ribs 62 extending inwardly and interposed between the elastic portions 52 of the respective charging terminals 5.
The holder body 61 has a rectangular plate shape, and a plurality of window portions 611 on which a plurality of terminal surfaces 51 are exposed are formed. The upper, lower, left, and right wall portions 612 forming each window portion 611 cover the upper, lower, left, and right edges 511 of the terminal surface 51 fitted in each window portion 611 from the surface side. That is, as shown in FIG. 7, each wall part 612 is formed wide toward the surface side. As shown in FIG. 6, each window portion 611 is formed with three rectangular pin holes 613 formed by support pins (not shown) that support each terminal surface 51 during insert molding. . Further, as shown in FIGS. 4 and 5, a plurality of convex portions 614 are formed on the back surface of the holder main body 61 so as to protrude toward the operation unit side body 2 and hold the base end portion of each elastic portion 52. .
Ribs 62 are provided on both sides of each of the convex portions 614 (on both sides of the elastic portion 52). The rib 62 extends substantially perpendicular to the back surface of the holder body 61 and has substantially the same length as the elastic portion 52.

ここで、充電端子部４のインサート成形方法について説明する。
金型内に三つの支持ピンを配置しておき、これら支持ピンで充電端子５の端子面５１を三点で支持させて、複数の充電端子５を所定間隔に配置する。次いで、金型内に樹脂を注入することによって所望形状に成形した後、支持ピンを取り除いて脱型することによって充電端子部４が形成される。 Here, an insert molding method of the charging terminal portion 4 will be described.
Three support pins are arranged in the mold, and the terminal surfaces 51 of the charge terminals 5 are supported at three points by these support pins, and the plurality of charge terminals 5 are arranged at predetermined intervals. Next, the resin terminal is molded into a desired shape by injecting resin into the mold, and then the support terminal is removed and the mold is removed to form the charging terminal portion 4.

このようにして構成された充電端子部４は、図４に示すように、ホルダ本体６が操作部側筐体２に形成された取付固定部２６の凹部２６１内に嵌め込まれ、凹部２６１に形成された開口部２６２を通ってホルダ６のリブ６２及び弾性部５２が操作部側筐体２内へと延在し、弾性部５２の先端が回路基板２２に形成された基板端子２３に接触している。なお、ホルダ本体６１と取付固定部２６の凹部２６１とは、防水テープ６３によって固定されており、開口部２６２を介して水が侵入できない防水構造とされている。   As shown in FIG. 4, the charging terminal portion 4 configured in this manner is formed in the concave portion 261 by fitting the holder body 6 into the concave portion 261 of the mounting fixing portion 26 formed in the operation unit side body 2. The rib 62 and the elastic part 52 of the holder 6 extend into the operation unit side body 2 through the opened opening 262, and the tip of the elastic part 52 contacts the board terminal 23 formed on the circuit board 22. ing. Note that the holder main body 61 and the concave portion 261 of the attachment fixing portion 26 are fixed by a waterproof tape 63 and have a waterproof structure in which water cannot enter through the opening 262.

一方、図１に示すように、充電台２００のポケット２０１内には充電端子部４の端子面５１と当接することによって充電端子部４に電力を供給する給電端子２０２が設けられている。また、ポケット２０１内には、スイッチレバー２０３が設けられており、スイッチレバー２０３が押圧されることによって、給電端子２０２による電力供給が開始されるようになっている。
充電台２００に折り畳み式携帯電話機１００がセットされると、操作部側筐体２の側面によりスイッチレバー２０３が押圧され、給電端子２０２による充電端子部４への電力供給が開始される。 On the other hand, as shown in FIG. 1, a power supply terminal 202 that supplies power to the charging terminal portion 4 by contacting the terminal surface 51 of the charging terminal portion 4 is provided in the pocket 201 of the charging stand 200. Further, a switch lever 203 is provided in the pocket 201, and power supply by the power supply terminal 202 is started when the switch lever 203 is pressed.
When the foldable mobile phone 100 is set on the charging stand 200, the switch lever 203 is pressed by the side surface of the operation unit side body 2, and power supply to the charging terminal unit 4 by the power supply terminal 202 is started.

以上、本発明の実施の形態によれば、操作部側筐体２に充電端子部４のホルダ６を防水を図りながら固定し、充電端子部４を回路基板２２の基板端子２３に固定しないで、充電端子部４と基板端子２３とを電気的に接続しているので、落下衝撃等が加わった場合に充電端子部４と基板端子２３との接触面に衝撃が集中して充電端子部４や回路基板２２が破損するといった問題が生じることがない。
充電端子部４は、その端子面５１の各縁部５１１がホルダ６の窓部６１１を形成する上下左右の壁部６１２によって覆われて操作部側筐体２の外部に露出しないように構成されているので、端子面５１の各縁部５１１から水が浸入することを防ぐことができ、防水性能に優れた構造とすることができる。
充電端子部４は、その端子面５１から延在するとともに、基板端子２３に弾性力を付与して接触する弾性部５２を有するので、落下衝撃等で回路基板２２が操作部側筐体２内でずれた場合でも弾性部５２が撓むことによって、充電端子部４と基板端子２３との間に衝撃が集中しない。よって、充電端子部４や回路基板２２の破損等を確実に防止することができる。
弾性部５２の両脇にリブ６１が設けられているので、リブ６２によって弾性部５２がある一定以上に撓まないように防止でき、その結果、弾性部５２のへたりを防止することができる。 As described above, according to the embodiment of the present invention, the holder 6 of the charging terminal unit 4 is fixed to the operation unit side body 2 while waterproofing, and the charging terminal unit 4 is not fixed to the board terminal 23 of the circuit board 22. Since the charging terminal portion 4 and the substrate terminal 23 are electrically connected, when a drop impact or the like is applied, the impact concentrates on the contact surface between the charging terminal portion 4 and the substrate terminal 23 and the charging terminal portion 4. And the problem that the circuit board 22 is damaged does not occur.
The charging terminal portion 4 is configured such that each edge portion 511 of the terminal surface 51 is covered by the upper, lower, left and right wall portions 612 forming the window portion 611 of the holder 6 and is not exposed to the outside of the operation unit side body 2. Therefore, it is possible to prevent water from entering from each edge portion 511 of the terminal surface 51, and a structure having excellent waterproof performance can be obtained.
Since the charging terminal portion 4 has an elastic portion 52 that extends from the terminal surface 51 and makes contact with the substrate terminal 23 by applying an elastic force, the circuit board 22 is placed in the operation unit side body 2 due to a drop impact or the like. Even when they are displaced, the elastic portion 52 bends, so that the impact is not concentrated between the charging terminal portion 4 and the substrate terminal 23. Therefore, damage to the charging terminal portion 4 and the circuit board 22 can be reliably prevented.
Since the ribs 61 are provided on both sides of the elastic part 52, the ribs 62 can prevent the elastic part 52 from being bent more than a certain amount, and as a result, the elastic part 52 can be prevented from sag. .

なお、本発明は上記実施の形態に限定されるものではなく、その要旨を逸脱しない範囲で適宜変更可能である。
例えば、上記実施の形態では、端子防水構造として充電用として使用される充電端子部４を例に挙げて説明したが、これに限らず、データ通信端子にも適用することができる。
また、上記充電端子５を構成する端子面５１と弾性部５２とは、板金を折り曲げることによって一体形成したものであったが、端子面５１と弾性部５２とを別体に形成しても良い。
上記実施の形態では、防水端子構造を備えた電子機器として折り畳み式携帯電話機１００を例に挙げて説明したが、これに限らず、ノート型パーソナルコンピュータ、デジタルカメラ、腕時計、ＰＤＡ（Personal Digital Assistance）、電子手帳、ウェラブルパソコン、携帯型無線機、その他の電子機器に本発明を適用しても良い。 In addition, this invention is not limited to the said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above-described embodiment, the charging terminal portion 4 used for charging as the terminal waterproof structure has been described as an example. However, the present invention is not limited to this and can be applied to a data communication terminal.
Moreover, although the terminal surface 51 and the elastic part 52 which comprise the said charge terminal 5 were integrally formed by bending a sheet metal, you may form the terminal surface 51 and the elastic part 52 separately. .
In the above embodiment, the foldable mobile phone 100 has been described as an example of an electronic device having a waterproof terminal structure. However, the present invention is not limited thereto, and is not limited to a notebook personal computer, digital camera, watch, PDA (Personal Digital Assistance).
