従来より、第１基板を有する第１の筐体と、第２基板を有する第２の筐体とを備え、該第１の筐体と第２の筐体とが、ヒンジ部によって折畳み開閉自在に連結された折畳み式電子機器は知られている。 Conventionally, a first housing having a first substrate and a second housing having a second substrate are provided, and the first housing and the second housing can be folded and opened by a hinge portion. Foldable electronic devices connected to are known.

このような折畳み式電子機器として、例えば、特許文献１では、折畳み部を介して連結される第１の筐体と第２の筐体とを有する携帯情報端末において、第１の筐体に第１部材と、該第１部材に重なり合うように接続される第２部材とを設け、第２の筐体に第３部材と、該第３部材に重なり合うように接続される第４部材とを設け、折畳み部に、第１部材に設けられた第１リング部と、第２部材に設けられた第２リング部と、第３部材に設けられた第３リング部と、第１，第２，第３リング部のそれぞれを同軸に接続し、回動可能に支持するヒンジ部材とを設けたものが開示されている。 As such a foldable electronic device, for example, in Patent Document 1, in a portable information terminal having a first casing and a second casing that are connected via a folding portion, the first casing is the first casing.

しかしながら、上記特許文献１の携帯情報端末では、第１の筐体の開閉操作を補助する弾性部材を備えた金属製のヒンジ部材を左右一対設ける必要があるので、部品点数が多くなり、コストアップ及び質量の増加という問題がある。 However, in the portable information terminal disclosed in Patent Document 1, since it is necessary to provide a pair of left and right metal hinge members provided with an elastic member that assists the opening and closing operation of the first housing, the number of parts increases and the cost increases. And the problem of increased mass.

また、ヒンジ部材を左右一対設けているため、第１の筐体と第２の筐体との間の信号をつなぐ信号線をヒンジ部材を設けた部分よりも内側の第１の筐体の空部及び第２の筐体の空部に通過させなければならず、ヒンジ部の空部の分割数が増える。このため、見映えが悪い上、各空部間の隙間から水やゴミが侵入しやすいという問題がある。 In addition, since the pair of hinge members are provided on the left and right, the signal line connecting the signals between the first housing and the second housing is connected to the empty space in the first housing inside the portion where the hinge member is provided. Part and the empty part of the second casing must be passed, and the number of divisions of the empty part of the hinge part increases. For this reason, there is a problem in that it looks bad and water and dust easily enter from the gaps between the empty portions.

さらに、上記特許文献２のようなフレキシブルプリント基板で第１の筐体と第２の筐体との間の信号をつなぐ信号線を構成するようにすると、フレキシブルプリント基板は、ある程度の幅を有するので、ヒンジ部の幅が大きくなると共に、信号線の配線が容易ではないという問題がある。 Furthermore, when a signal line for connecting signals between the first housing and the second housing is formed by the flexible printed circuit board as in Patent Document 2, the flexible printed circuit board has a certain width. Therefore, there is a problem that the width of the hinge portion is increased and the signal lines are not easily wired.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、ヒンジ部の構成を簡易にして組付性、コストパフォーマンス及び外観の見映えを向上させると共に、軽量化を図ることにある。 The present invention has been made in view of the above points, and an object of the present invention is to simplify the configuration of the hinge portion to improve the assembling property, cost performance, and appearance, and to reduce the weight. There is.

上記の目的を達成するために、この発明では、第１の筐体の開閉操作を補助する弾性部材を備えた開閉軸を第１の筐体の片側にのみ設けるようにした。 In order to achieve the above object, according to the present invention, an opening / closing shaft provided with an elastic member for assisting an opening / closing operation of the first housing is provided only on one side of the first housing.

具体的には、第１の発明では、第１基板を有する第１の筐体と、第２基板を有する第２の筐体とを備え、該第１の筐体と第２の筐体とが、ヒンジ部によって折畳み開閉自在に連結された折畳み式電子機器を対象とする。 Specifically, in the first invention, a first casing having a first substrate and a second casing having a second substrate are provided, and the first casing and the second casing are provided. However, the present invention is intended for a folding electronic device that is connected by a hinge part so as to be freely opened and closed.

そして、上記ヒンジ部は、上記第２の筐体から垂直に膨出した中空の膨出部と、上記第１の筐体に設けられて上記膨出部を両側から挟み込む樹脂製の第１及び第２外筒とを備え、
上記第１外筒から膨出部の該第１外筒側端部に渡り、上記第１の筐体の開閉操作を補助する弾性部材を備えた開閉軸が挿入され、
上記第２外筒から膨出部の該第２外筒側端部に渡り、中空の内筒が挿入され、
上記第１基板と第２基板とを接続する信号線は、上記膨出部と第２外筒と内筒の内部を通過する構成とする。 The hinge portion includes a hollow bulge portion that bulges perpendicularly from the second housing, and a resin-made first and second resin that is provided in the first housing and sandwiches the bulge portion from both sides. A second outer cylinder,
An opening / closing shaft provided with an elastic member for assisting the opening / closing operation of the first housing is inserted from the first outer cylinder to the first outer cylinder side end of the bulging portion,
A hollow inner cylinder is inserted from the second outer cylinder to the second outer cylinder side end of the bulging portion,
A signal line connecting the first substrate and the second substrate passes through the bulging portion, the second outer cylinder, and the inner cylinder.

上記の構成によると、第１の筐体の開閉操作を補助する弾性部材を備えた開閉軸を第１の筐体における一方の外筒にのみ設けているので、従来のように第２の筐体から垂直に膨出した中空の膨出部を分割してその間に第１の筐体より延びる空部を挿入し、これら膨出部と空部との間に第１基板と第２基板とを接続する信号線を挿通する必要がなく、信号線を膨出部と第２外筒と内筒との内部に挿通することができるので、膨出部をコンパクトにすることができる。また、信号線は第２外筒内を通過することができるので、信号線の配線が容易である。さらに、第１及び第２外筒を樹脂で構成しているので、金属製のヒンジ部に比べて質量が軽い。 According to the above configuration, since the opening / closing shaft provided with the elastic member for assisting the opening / closing operation of the first casing is provided only on one outer cylinder of the first casing, the second casing is conventionally provided. A hollow bulging portion that bulges vertically from the body is divided, and an empty portion extending from the first housing is inserted therebetween, and the first substrate and the second substrate are interposed between the bulging portion and the empty portion. There is no need to insert a signal line for connecting the signal line, and the signal line can be inserted into the bulging part, the second outer cylinder, and the inner cylinder, so that the bulging part can be made compact. Further, since the signal line can pass through the second outer cylinder, the signal line can be easily wired. Furthermore, since the 1st and 2nd outer cylinder is comprised with resin, mass is light compared with a metal hinge part.

第２の発明では、上記第１及び第２外筒は、上記第１の筐体よりも高強度及び高剛性の樹脂材料で形成され、該第１の筐体に取り付けられる構成とする。 In the second invention, the first and second outer cylinders are made of a resin material having higher strength and rigidity than the first casing, and are attached to the first casing.

すなわち、ヒンジ部を構成する第１及び第２外筒は、第１の筐体と第２の筐体との開閉操作を行う際に大きな荷重が加わるが、上記の構成によると、これら第１及び第２外筒を高強度及び高剛性の樹脂で形成しているので、開閉操作を繰り返し行っても破損したり、ガタが生じたりすることはない。また、第１及び第２外筒を第１の筐体と別に形成しているので、第１の筐体は、比較的強度の低い安い材料で形成することができる。 That is, a large load is applied to the first and second outer cylinders constituting the hinge portion when the first casing and the second casing are opened / closed. And since the 2nd outer cylinder is formed with high intensity | strength and highly rigid resin, even if it repeats opening and closing operation, it will not be damaged or a play will not arise. In addition, since the first and second outer cylinders are formed separately from the first casing, the first casing can be formed from a cheap material with relatively low strength.

第３の発明では、上記内筒は、上記第２外筒及び膨出部よりも耐摩耗性の高い樹脂材料で構成されている。 In 3rd invention, the said inner cylinder is comprised with the resin material whose abrasion resistance is higher than the said 2nd outer cylinder and a bulging part.

すなわち、ヒンジ部を構成する第２外筒に設けた内筒は、第１の筐体と第２の筐体との開閉操作を行う際に摺動し、摩擦力が繰り返し加わって摩耗しやすいが、上記の構成によると、内筒を第２外筒及び膨出部よりも耐摩耗性の高い樹脂材料で構成しているので、開閉操作を繰り返し行っても内筒が摩耗しない。 That is, the inner cylinder provided in the second outer cylinder constituting the hinge portion slides when the first casing and the second casing are opened and closed, and is easily worn due to repeated frictional force. However, according to said structure, since the inner cylinder is comprised with the resin material whose abrasion resistance is higher than a 2nd outer cylinder and a bulging part, even if it repeats opening and closing operation, an inner cylinder does not wear.

第４の発明では、上記信号線は、その両端部を除く中間部で複数の細い電線が一本に束ねられ、該束ねられた状態で、その外周が、複数の導線をメッシュ状に編んだグランド線で覆われ、
上記第２外筒には、上記グランド線の一端に接続されるアース板金が設けられ、該アース板金は、上記第１基板に接地され、
上記グランド線の他端は、上記第２基板に接地されている。 In a fourth aspect of the invention, the signal line is formed by bundling a plurality of thin electric wires into one at an intermediate portion excluding both ends thereof, and the outer periphery of the signal line is knitted into a mesh shape. Covered with ground wire,
The second outer cylinder is provided with a ground metal plate connected to one end of the ground wire, and the ground metal plate is grounded to the first substrate,
The other end of the ground line is grounded to the second substrate.

上記の構成によると、信号線は、複数の細い電線が一本に束ねられた状態でメッシュ状のグランド線で覆われているので、外径が小さく押さえられている。この信号線のグランド線の一端が、第２外筒に設けたアース板金を介して第１基板に接地されるので、容易に膨出部及び内筒の内部を通過させて配線が行われ、第１基板と第２基板との間の電位差が小さくなる。 According to said structure, since the signal wire | line is covered with the mesh-like ground wire in the state in which the some thin electric wire was bundled together, the outer diameter is restrained small. Since one end of the ground line of the signal line is grounded to the first substrate via a ground metal plate provided in the second outer cylinder, wiring is easily performed by passing through the inside of the bulging portion and the inner cylinder, The potential difference between the first substrate and the second substrate is reduced.

第５の発明では、上記第１の筐体の内部には、伝導性のある金属製補強部材が設けられ、
上記第１基板は、上記補強部材に取り付けられ、
上記アース板金は、上記第２外筒が第１の筐体にビス止めされる際に上記補強部材に共締めされて接地される構成とする。 In the fifth invention, a conductive metal reinforcing member is provided inside the first housing,
The first substrate is attached to the reinforcing member,
The ground metal plate is configured to be grounded together with the reinforcing member when the second outer cylinder is screwed to the first housing.

上記の構成によると、アース板金が、第２外筒を第１の筐体にビス止めする際に第１の筐体に接地されるので、組付作業が容易である。 According to the above configuration, since the ground metal plate is grounded to the first casing when the second outer cylinder is screwed to the first casing, the assembling work is easy.

第６の発明では、折畳み式電子機器は、折畳み式携帯通信機器とする。 In the sixth invention, the foldable electronic device is a foldable portable communication device.

上記の構成によると、携帯通信機器は、コンパクトで軽量なものが好まれるが、本発明により、商品性が向上する。 According to the above configuration, the portable communication device is preferably compact and lightweight, but the present invention improves the merchantability.

第７の発明では、折畳み式電子機器は、折畳み式携帯電話機であり、
上記第１の筐体には、表示部が設けられ、
上記第２の筐体には、操作部が設けられる構成とする。 In the seventh invention, the foldable electronic device is a foldable mobile phone,
The first casing is provided with a display unit,
The second casing is provided with an operation unit.

上記の構成によると、比較的軽量な表示部側が第１の筐体に設けられ、バッテリーなどが設けられて質量の重い操作部が第２の筐体に設けられる。このため、膨出部のある第２の筐体に比して第１の筐体の小型軽量化が可能となる。 According to said structure, the comparatively lightweight display part side is provided in a 1st housing | casing, a battery etc. are provided and an operation part with a heavy mass is provided in a 2nd housing | casing. For this reason, the first housing can be made smaller and lighter than the second housing having the bulging portion.

第８の発明では、上記第１の筐体の平面視の外形は、上記第２の筐体の平面視の外形よりも小さい構成とする。 In the eighth invention, the outer shape of the first casing in plan view is smaller than the outer shape of the second casing in plan view.

上記の構成によると、第２の筐体を片手でつかんだ状態で、第２の筐体よりも小さい第１の筐体を、第２の筐体をつかんだ手の指で押し上げて第１の筐体の開閉操作が行われる。本発明では、膨出部を分割する必要がなく、膨出部の幅を小さくできるので、第１の筐体を小さくし易い。 According to the above configuration, in a state where the second casing is held with one hand, the first casing which is smaller than the second casing is pushed up with the finger of the hand holding the second casing and the first casing is pressed. The opening / closing operation of the casing is performed. In the present invention, it is not necessary to divide the bulging portion, and the width of the bulging portion can be reduced.

以上説明したように、上記第１の発明によれば、第１の筐体の第１及び第２外筒を樹脂で構成し、弾性部材を有する開閉軸を第１外筒にのみ設け、信号線を膨出部と第２外筒と内筒との内部に通過させている。このため、ヒンジ部の構成を簡易にして組付性、コストパフォーマンス及び外観の見映えを向上させると共に、軽量化を図ることができる。 As described above, according to the first invention, the first and second outer cylinders of the first casing are made of resin, the opening / closing shaft having the elastic member is provided only on the first outer cylinder, The wire is passed through the bulging portion, the second outer cylinder, and the inner cylinder.

For this reason, it is possible to prevent damage to the first and second outer cylinders by repeatedly performing the opening and closing operation, and only the portion requiring strength is formed of a high-strength and high-rigidity resin material. Good performance.

上記第３の発明によれば、内筒を耐摩耗性の高い樹脂材料としている。このため、開閉操作を繰り返し行うことによる内筒の摩耗を防ぐことができると共に、樹脂材料で構成しているので、さらに軽量化を図ることができる。 According to the third aspect, the inner cylinder is made of a highly wear-resistant resin material. For this reason, while being able to prevent abrasion of the inner cylinder by repeatedly performing the opening and closing operation, since it is made of a resin material, it is possible to further reduce the weight.

上記第４の発明によれば、信号線を、複数の細い電線を一本に束ねた状態でメッシュ状のグランド線で覆い、このグランド線の一端を第２外筒に設けたアース板金に接続して第１基板に接地し、他端を第２基板に接地している。このため、信号線の外径が小さく押さえられるので、容易に配線を行うことができ、さらに組付性を向上させることができると共に、第１基板と第２基板との間の電位差を確実に小さくして誤動作を防止することができる。 According to the fourth aspect of the invention, the signal line is covered with a mesh-like ground line in a state where a plurality of thin electric wires are bundled together, and one end of the ground line is connected to the ground sheet metal provided on the second outer cylinder. Thus, the first substrate is grounded, and the other end is grounded to the second substrate. For this reason, since the outer diameter of the signal line can be kept small, wiring can be easily performed, and the assembly can be improved, and the potential difference between the first substrate and the second substrate can be reliably ensured.
