Description

本発明は、例えば2つの筐体を互いにスライドさせることによって伸縮させるようにした携帯電話機等のように、相対動作する筐体間の電気回路を、基板接続コネクタを介して接続させた電子機器において、その基板接続コネクタの取り付け部分を防水状態とする基板接続コネクタの防水取付け構造に関する。   The present invention relates to an electronic apparatus in which an electrical circuit between relatively operating casings is connected via a board connection connector, such as a mobile phone that is expanded and contracted by sliding two casings relative to each other. Further, the present invention relates to a waterproof mounting structure for a board connecting connector in which the board connecting connector mounting portion is waterproof.

従来、携帯電話においては2つの筐体を互いにスライドさせることによって伸長・短縮させるようにした携帯電話機等、2つの筐体を相対動作させることによって伸縮させるようにした構造のものが普及している。このような携帯用電子機器においては、各筐体間はフレキシブルプリント基板（ＦＰＣ）等の接続配線により接続され、各筐体間で電気信号の送受信が実現される。   2. Description of the Related Art Conventionally, mobile phones having a structure in which two casings are expanded and contracted by sliding relative to each other, such as mobile phones that are extended and shortened by sliding the two casings relative to each other, have become widespread. . In such a portable electronic device, the housings are connected by connection wiring such as a flexible printed circuit board (FPC), and electrical signals can be transmitted and received between the housings.

このような電子機器において近年、防水処理を施したものが開発されており、各筐体間の接続配線部分の防水方法として、筐体に設けた接続配線の挿入口から筐体内へ水が入ることを防ぐため、接続配線の外周部に筐体の挿入口を閉塞するキャップを設け、キャップの外周部にパッキンを設け、挿入口を水密に封止する構造とするものがある（例えば、特許文献１）。キャップは、例えば金型内に接続配線を装填した後、樹脂を注入して接続配線を溶融樹脂で包んで固化させるインサート成形を行うことで、接続配線の外周部と一体に形成している。   In recent years, such an electronic device that has been waterproofed has been developed. As a method of waterproofing the connection wiring portion between the housings, water enters the housing from the connection wiring insertion port provided in the housing. In order to prevent this, there is a structure in which a cap for closing the insertion port of the housing is provided on the outer peripheral portion of the connection wiring, a packing is provided on the outer peripheral portion of the cap, and the insertion port is sealed in a watertight manner (for example, a patent Reference 1). The cap is formed integrally with the outer periphery of the connection wiring by, for example, insert molding in which a connection wiring is loaded into a mold, and then resin is injected and the connection wiring is wrapped with a molten resin and solidified.

また、この他に、筐体に対してコネクタプラグが挿入される窓穴を形成しておき、筐体外の外側プリント基板に固定したコネクタプラグを窓孔に挿入して内部のコネクタソケットに嵌合させ、その外側プリント基板と筐体の窓孔縁部外面との間にパッキンを介在させ、外側プリント基板の外面を、筐体にネジ止めした押圧板にて押圧させることによって窓孔を閉鎖させるようにしたもの（例えば特許文献２）が提案されている。   In addition to this, a window hole into which the connector plug is inserted into the housing is formed, and the connector plug fixed to the outer printed board outside the housing is inserted into the window hole and fitted into the internal connector socket. Then, a packing is interposed between the outer printed circuit board and the outer surface of the edge of the window hole of the housing, and the outer surface of the outer printed circuit board is pressed by a pressing plate screwed to the housing to close the window hole. What has been made (for example, Patent Document 2) has been proposed.

上述した従来の基板接続コネクタの防水取付け構造の内、筐体に設けた接続配線の挿入口から筐体内へ水が入ることを防ぐため、接続配線の外周部に筐体の挿入口を閉塞するキャップを設ける構造は、部品の加工のコストが高いという問題があった。   Of the above-described waterproof mounting structure of the conventional board connection connector, the housing insertion port is closed to the outer periphery of the connection wiring in order to prevent water from entering into the housing from the connection wiring insertion port provided in the housing. The structure in which the cap is provided has a problem that the cost of processing the parts is high.

また、外側プリント基板と筐体の窓孔縁部外面との間にパッキンを介在させ、外側プリント基板の外面を、筐体にネジ止めした押圧板にて押圧させる構造は、パッキンの他に筐体に押圧板が必要であり、部品数が多くなるとともに組み立て工数が多いという問題があった。   A structure in which a packing is interposed between the outer printed circuit board and the outer surface of the edge of the window hole of the housing and the outer surface of the outer printed circuit board is pressed by a pressing plate screwed to the housing is a housing other than the packing. There is a problem in that a pressing plate is required on the body, and the number of parts increases and the number of assembly steps increases.

本発明はこのような従来の問題に鑑み、部品数が少なく加工コストが低く、かつ組み立て工数が従来に比べて少ない基板接続コネクタの防水取付け構造の提供を目的としてなされたものである。   In view of such a conventional problem, the present invention has been made for the purpose of providing a waterproof mounting structure for a board connecting connector with a small number of components, a low processing cost, and a small number of assembly steps as compared with the conventional art.

上述の如き従来の問題を解決し、初期の目的を達成する請求項１に記載の発明の特徴は、筐体内の内側プリント基板に固定されたコネクタソケットと、前記筐体外の外側プリント基板に固定されたコネクタプラグとを、前記筐体に開口させた窓孔を通して互いに嵌合させることによって内外のプリント基板を互いに接続させる基板接続コネクタを前記筐体に対し水密を持たせて取り付ける基板接続コネクタの防水取付け構造であって、前記コネクタソケットを、前記窓孔内を通して筐体外に露出させ、該コネクタソケットに、その外側プリント基板側面の周縁部と該コネクタソケットの窓孔内面と対向する周側面とに跨らせたリング状のゴム状弾性材からなるシール材を嵌め付け、該シール材をもって前記コネクタソケットの外周側面と窓孔内面との隙間の水密性を持たせるとともに、前記コネクタプラグのコネクタソケットに嵌合することによって、前記シール材をコネクタソケット周囲の外側プリント基板表面に圧接させてコネクタソケットとの間の水密性を持たせたことにある。   The feature of the invention according to claim 1, which solves the conventional problems as described above and achieves the initial object, is a connector socket fixed to the inner printed board inside the casing, and fixed to the outer printed board outside the casing. A board connection connector for attaching a board connection connector for connecting an inner and an outer printed board to each other by fitting the connector plug with each other through a window hole opened in the casing while keeping watertightness to the casing. In the waterproof mounting structure, the connector socket is exposed to the outside of the housing through the window hole, and a peripheral side surface of the outer side of the outer printed circuit board and a peripheral side surface facing the inner surface of the window hole of the connector socket are exposed to the connector socket. A seal material made of a ring-like rubber-like elastic material straddled on the outer periphery of the connector socket and the window hole is fitted with the seal material. The sealing material is pressed against the outer printed circuit board surface around the connector socket so that the watertightness between the connector socket and the connector socket is obtained by fitting the connector plug with the connector socket. It is in having it.

請求項２に記載の発明の特徴は、請求項１の構成に加え、前記コネクタソケットの外周側面にシール材嵌合用の環状凹溝を備えるとともに前記シール材の内周面に該環状凹溝に嵌り合う凸条を一体に備え、該凸条を前記環状凹溝に嵌め合わせることによって該シール材をコネクタソケットに対して抜け止めしたことにある。   According to a second aspect of the present invention, in addition to the configuration of the first aspect, an annular groove for fitting a sealing material is provided on the outer peripheral side surface of the connector socket, and the annular groove is formed on the inner peripheral surface of the sealing material. The fitting is integrally provided with fitting ridges, and the sealing material is prevented from coming off from the connector socket by fitting the ridges into the annular groove.

請求項３に記載の発明の特徴は、請求項１又は２何れかの請求項の構成に加え、前記シール材と外側プリント基板表面との圧接は、外側プリント基板によってシール材に圧縮方向に弾性変形させた状態で前記コネクタプラグをコネクタソケットに対して抜け止めされた状態とすることによってなされていることにある。   According to a third aspect of the present invention, in addition to the configuration of the first or second aspect, the pressure contact between the sealing material and the surface of the outer printed board is elastic in the compression direction by the outer printed board. This is because the connector plug is kept from being detached from the connector socket in a deformed state.

本発明においては、コネクタソケットを、筐体に形成した窓孔内を通して筐体外に露出させ、該コネクタソケットと前記窓孔との間及び該コネクタソケットの外側プリント基板側面と前記コネクタプラグ外周の外側プリント基板面との間をシール材によってシールすることによって、筐体と基板接続コネクタ間及び該基板接続コネクタ内を防水するようにしたことによって、防水のために使用する部品が従来に比べて少なく、その加工コストも低く、組み立て工数も少なく、低コストでの基板接続コネクタの防水取付けがなされる。   In the present invention, the connector socket is exposed outside the casing through the window hole formed in the casing, and between the connector socket and the window hole, on the outer printed circuit board side surface of the connector socket, and outside the outer periphery of the connector plug. By sealing between the printed circuit board surface with a sealing material, the space between the housing and the board connection connector and the inside of the board connection connector are waterproof, so that less parts are used for waterproofing than in the past. The processing cost is low, the number of assembling steps is small, and waterproof mounting of the board connector is performed at low cost.

また、本発明においては、コネクタソケットに、その外側プリント基板側面の周縁部と該コネクタソケットの窓孔内面と対向する周側面とに跨らせたリング状のゴム状弾性材からなるシール材を嵌め付け、該シール材をもって前記コネクタソケットの外周側面と窓孔内面との隙間の水密性を持たせるとともに、前記コネクタプラグのコネクタソケットに嵌合することによって、前記シール材をコネクタソケット周囲の外側プリント基板表面に圧接させてコネクタソケットとの間の水密性を持たせることによって、シール材が１個でよく、しかもコネクタソケットに対するコネクタプラグの嵌合によって防水性をもたせた装着ができるため、加工コストが高くならず、組み立て工数も少ないという効果がある。   Further, in the present invention, the connector socket is provided with a sealing material made of a ring-like rubber-like elastic material straddling the peripheral portion of the side surface of the outer printed board and the peripheral side surface facing the inner surface of the window hole of the connector socket. The sealing material is fitted to the connector socket of the connector plug so that the sealing material is provided with water tightness in the gap between the outer peripheral side surface of the connector socket and the inner surface of the window hole. By making pressure contact with the printed circuit board surface and providing watertightness between the connector socket and the connector socket, only one seal material is required, and the connector plug can be fitted with a connector socket to provide waterproofness. Costs are not increased and the number of assembly steps is reduced.

本発明においては、前記コネクタソケットの外周側面にシール材嵌合用の環状凹溝を備えるとともに前記シール材の内周面に該環状凹溝に嵌り合う凸条を一体に備え、該凸条を前記環状凹溝に嵌め合わせることによって該シール材をコネクタソケットに対して抜け止めすることにより、コネクタソケットに予めシール材を脱落しない状態で装着しておくことができ、組み立てが容易となる。   In the present invention, an annular groove for fitting a sealing material is provided on the outer peripheral side surface of the connector socket, and a protrusion that fits in the annular groove is integrally provided on the inner peripheral surface of the sealing material. By fitting the annular groove into the annular groove to prevent the sealing material from coming off from the connector socket, the sealing material can be attached to the connector socket in advance without dropping off, and assembly is facilitated.

更に本発明においては、前記シール材と外側プリント基板表面との圧接を、外側プリント基板によってシール材に圧縮方向に弾性変形させた状態で前記コネクタソケットに対するコネクタプラグを抜け止め状態とすることによってなすようにすることにより、従来の基板接続コネクタに使用されているコネクタソケットに対するコネクタプラグのロック機構が利用でき、従来の量産品パーツをそのまま使用でき、加工コストが廉価となる。   Furthermore, in the present invention, the pressure contact between the sealing material and the surface of the outer printed board is performed by keeping the connector plug with respect to the connector socket in a state in which the sealing material is elastically deformed in the compression direction by the outer printed board. By doing so, the locking mechanism of the connector plug with respect to the connector socket used for the conventional board connection connector can be used, and the conventional mass-produced part can be used as it is, and the processing cost is reduced.

そして、図１に示すようにコネクタプラグ１１の凸条１６をコネクタプラグ嵌合凹溝１３内に嵌め合わせることによって互いに対応した接触子１４，１７が接触し、電気接続されるようになっている。また、この時、コネクタソケット１０の接触子１４に形成されている係合凹部１８に、コネクタプラグ１１の接触子１７形成されている係合凸部１９が嵌り合うことによって、コネクタソケット１０に対するコネクタプラグ１１の抜け止めがなされるようになっており、係合凹部１８と係合凸部１９とによって抜け止め機構を構成している。   Then, as shown in FIG. 1, the corresponding contacts 14 and 17 are brought into contact with each other and electrically connected by fitting the protrusion 16 of the connector plug 11 into the connector plug fitting groove 13. . At this time, the engagement protrusion 19 formed on the contact 17 of the connector plug 11 is fitted into the engagement recess 18 formed on the contact 14 of the connector socket 10, so that the connector socket 10 is connected to the connector socket 10. The plug 11 is prevented from coming off, and the engaging concave portion 18 and the engaging convex portion 19 constitute a retaining mechanism.

コネクタソケット１０は、窓孔３内を通して筐体１外に露出されているとともに、コネクタソケット１０と窓孔３との間と、コネクタソケット１０の頂面、即ち外側プリント基板５側の面と前記コネクタプラグ外周の外側プリント基板面との間とをシール材２０によってシールすることにより、筐体１と基板接続コネクタ４との間及び該基板接続コネクタ４内を防水している。   The connector socket 10 is exposed to the outside of the housing 1 through the window hole 3, and between the connector socket 10 and the window hole 3, the top surface of the connector socket 10, that is, the surface on the outer printed circuit board 5 side, The space between the outer periphery of the connector plug and the outer printed board surface is sealed with a sealing material 20, thereby waterproofing the space between the housing 1 and the board connection connector 4 and the inside of the board connection connector 4.

シール材２０は、ゴム状弾性材によってリング状に形成されており、コネクタソケット１０の頂面周縁部を覆う平板リング状の頂面部２０ａと、その周縁から下向きに一体に垂下された筒状部２０ｂとからなる断面Ｌ字状をなしている。筒状部２０ｂの内周面には、周方向に連続した凸条２１が一体に突設されている。   The sealing material 20 is formed in a ring shape by a rubber-like elastic material, and a flat plate ring-shaped top surface portion 20a that covers the peripheral surface of the top surface of the connector socket 10, and a cylindrical portion that is integrally suspended downward from the periphery. It has an L-shaped cross section consisting of 20b. On the inner peripheral surface of the cylindrical portion 20b, a convex strip 21 continuous in the circumferential direction is integrally projected.

コネクタソケット１０の外周面には、前記凸条２１が嵌り合うシール材嵌合用の環状凹溝２２が形成されており、この環状凹溝２２内に突条２１を嵌め合わせることによってコネクタソケット１０に対するシール材２０の抜け止めがなされるようになっている。また、頂面部２０ａが、コネクタソケット１０の頂面に密着した状態で環状凹溝２２に対する凸条２１の嵌合がなされるように形成されている。   On the outer peripheral surface of the connector socket 10, an annular groove 22 for fitting the sealing material into which the ridge 21 is fitted is formed. By fitting the ridge 21 into the annular groove 22, the connector socket 10 is attached to the connector socket 10. The sealing material 20 is prevented from coming off. Further, the top surface portion 20 a is formed so that the protrusions 21 are fitted to the annular groove 22 in a state in which the top surface portion 20 a is in close contact with the top surface of the connector socket 10.

シール材２０をコネクタソケット１０に装着した状態でコネクタソケット１０を窓孔３内に押し込むことにより、シール材２０の筒状部２０ｂが半径方向に弾性変形した状態で、窓孔３の内周面とシール材嵌合用凹溝２２の底面との間に介在され、これによってコネクタソケット１０と窓孔３との間を水密状態にシールしている。   The inner peripheral surface of the window hole 3 in a state where the cylindrical portion 20b of the sealing material 20 is elastically deformed in the radial direction by pushing the connector socket 10 into the window hole 3 with the sealing material 20 mounted on the connector socket 10.

At this time, the connector socket 10 and the connector plug 11 have the engagement concave portions 18 and the engagement convex portions 19 of the contact pieces 14 and 17 in a state where the top surface portion 20a of the sealing material 20 is elastically deformed in the thickness direction. The upper and lower surfaces of the top surface portion 20a of the sealing material 20 are kept in pressure contact with the top surface of the connector socket 10 and the surface of the outer printed circuit board 5 so that watertightness is maintained. It has become.

尚、本例ではコネクタソケット１０とコネクタプラグ１１との抜け止め機構が接触片１４，１７の係合によってなされている例を示しているが、このような接触片相互間の弾性抜け止め機構の他に、コネクタソケット１０とコネクタプラグ１１のハウジング相互間を係合する機構を利用したものであってもよい。   In this example, the retaining mechanism between the connector socket 10 and the connector plug 11 is shown by the engagement of the contact pieces 14 and 17, but such an elastic retaining mechanism between the contact pieces is shown. In addition, a mechanism that engages between the housings of the connector socket 10 and the connector plug 11 may be used.
