Description

本発明は，主にテレビ共同受信に利用されるテレビ共同受信機器に関し，詳しくはそのテレビ共同受信機器の取扱性を向上するための構造に関する。
The present invention relates to a television joint reception device mainly used for television joint reception, and more particularly to a structure for improving the handling of the television joint reception device.

従来のテレビ共同受信システムでは，テレビアンテナやＣＡＴＶ伝送路から宅内に引き込まれた信号は，同軸ケーブルや分配器等を介して所要数に分配され，当該分配された信号は更に同軸ケーブル等を介してテレビ端子まで伝送される。テレビ端子には宅内用の同軸ケーブルを接続することによって，この同軸ケーブルの先には，例えばテレビ受像機が接続されたり，更に分配器等を介してテレビ受像機やビデオに接続されたりするような構成となっていた。
（例えば，特許文献１の図に示す分配器，及び，特許文献２の図に示すシステム参照。）

このような受信システムにおいて使用されるテレビ端子からテレビ受像機用までの宅内用の同軸ケーブルは，このシステムを施工した業者がテレビ等の配置に基づいて，所定長さに加工して配設する場合や，ユーザー自らが材料をそろえて加工する場合もあるが，一般的にはテレビ受像機等の配置に合わせて，家人がＤＩＹショップや家電量販店等において，接続コネクタの加工済みのケーブルを購入してくる場合が多い。
（例えば，特許文献３参照）
In the conventional TV joint reception system, the signal drawn into the house from the TV antenna or the CATV transmission line is distributed to the required number via a coaxial cable or a distributor, and the distributed signal is further transmitted via a coaxial cable or the like. To the TV terminal. By connecting a coaxial cable for home use to the TV terminal, for example, a television receiver is connected to the end of this coaxial cable, and further, it is connected to a television receiver or video through a distributor or the like. It was the composition.
(For example, see the distributor shown in the figure of Patent Document 1 and the system shown in the figure of Patent Document 2.)

The coaxial cable for home use from the TV terminal to the TV receiver used in such a receiving system is processed and arranged to a predetermined length by the contractor who installed this system based on the arrangement of the TV and the like. In some cases, the user himself / herself prepares the material, but in general, a householder uses a processed cable for the connector connector at a DIY shop or a home appliance mass retailer, etc. according to the arrangement of the television receiver, etc. Often purchased.
(For example, see Patent Document 3)

特許第２８１９０３２号公報Japanese Patent No. 2819032 特開平９−２７５５１３号公報JP-A-9-275513 特開昭６３−３１０５８２号公報JP-A-63-310582

しかし，従来のようにテレビ端子からテレビ受像機へ接続する同軸ケーブルや，分配器とビデオ等を接続する同軸ケーブルを，それらの設置場所に応じて同軸ケーブルを切断して，その両端にＦ型プラグを取り付けるような場合は，その加工の手間がかかるばかりでなく，加工することに慣れていない一般ユーザーにとっては，非常に難しいものとなるばかりでなく，この場合の信頼性においても補償されるものではない。更に近年においてディジタル放送の受信をすることが多くなり，同軸ケーブルの選択やプラグの組み付けにおいてミスがあれば，そこから妨害信号が入り込むことによって，受信画像に影響を与える場合が発生して，美しい画像が見られないといった問題があった。
However, the conventional coaxial cable that connects the TV terminal to the television receiver or the coaxial cable that connects the distributor and video, etc., is cut according to the installation location, and F-type is connected to both ends. When a plug is attached, not only is it troublesome to process it, but it is very difficult for general users who are not used to processing, and the reliability in this case is also compensated. It is not a thing. In recent years, digital broadcasts are often received, and if there is a mistake in selecting a coaxial cable or assembling a plug, an interference signal may enter from there, which may affect the received image. There was a problem that the image could not be seen.

また，同軸ケーブルが所定の長さに切られており，当該同軸ケーブルの両端にはプラグが加工済みの製品が家電店等において売られているのであるが，これを使用する場合は，宅内に配線するのに最適な寸法の同軸ケーブルが無い場合は，長めの物を購入することによって，テレビ等の背面に長いまま設置したり，余分な長さ分だけを適当に束ねるなどしたりして設置していた。この場合は，テレビ等の背面は他のケーブル類と合わせて整理し難いものとなるといった問題があった。更に近年において急速に普及している液晶テレビのように，液晶テレビの設置場所を移動させて見るなどの新しい使い方がなされるようになってきたが，当該テレビの配置場所に合わせて同軸ケーブルをすっきりと配線するためには，テレビの設置位置が制限されるといった問題があった。
また，同軸ケーブルが長くなればなるほどそれを入れるための梱包材を大きくしたり，梱包材が変形しないように強化したりする必要が生じることで製品コストが高くなるといった問題もあった。 In addition, the coaxial cable is cut to a predetermined length, and products with plugs processed at both ends of the coaxial cable are sold at home appliance stores, etc. If there is no coaxial cable of the optimal dimensions for wiring, you can purchase a longer one and install it on the back of a TV or the like, or bundle the extra length appropriately. It was installed. In this case, there is a problem that the rear surface of the television or the like becomes difficult to organize together with other cables. Furthermore, like LCD TVs, which are rapidly spreading in recent years, new usages such as moving the viewing location of the LCD TV have come to be used, but a coaxial cable is used in accordance with the location of the television. There is a problem that the installation position of the TV is limited in order to make the wiring clean.
In addition, the longer the coaxial cable , the larger the packing material for inserting the coaxial cable , and the need to strengthen the packing material so that it does not deform.

本発明は，こうした問題点を解決するためになされたものであり，その目的は，常に配設する寸法に最適な長さに調整可能で，テレビ受像機等の背面であってもすっきりと配線可能なテレビ共同受信機器を提供することにある。 The present invention has been made to solve these problems, and its purpose is to be able to be adjusted to an optimum length for the dimensions to be always provided, and to clean the wiring even on the back of a television receiver or the like. It is to provide a TV joint receiving device that can be used .

Ｆ型接栓座３１は中心導体３１ａが軸体３０の軸線と同一線上になるにように軸体３０の一方端側に配設されると共に，該中心導体３１ａは前記収納部３６の内方向に突出している。同時に接続端子３１の外部導体の一部を突設形成した突出片３１ｂも収納部３６に突出するように配設されている。
先ず，この中心導体３１ａと突出片３１ｂには，前記可動用の同軸ケーブル２０の自由端側に加工された中心導体と外部導体を周知の方法によって固着する。
前記軸体の蓋体３４と軸体の本体３５との当接面の任意の位置には，相対向する位置に，前記同軸ケーブル２１を収納部３６から軸体３０の外方向に導入するための蓋体側の導入溝３８と，本体側の導入溝３９が形成されており，この両方の溝に沿って同軸ケーブル２１を配設し，前記蓋体３４と本体３５を組み付けることによって，前記同軸ケーブル２１を挟持するように構成されている。更に前記導入溝３８，３９夫々の内側には，内側方向に相互に対向しない任意の位置となるように，所定数の係止爪３８ａ，３９ａが突設させてあり，同軸ケーブルを引き抜いたり押し込んだりする力に対して，前記同軸ケーブル２１を強固に挟持すると共に，接続端子３１との接続点に力が加わって破損しないように構成されている。
更に，軸体を合成樹脂材料で成形した場合は，前記収納部３６の内部に収納される金属材料で形成されたシールドケースを収納し，このシールドケースの内部において，前記同軸ケーブル２１の中心導体と前記接続端子の中心導体３１ａとを接続するように構成することによって，外来電波による妨害を低減するように構成しても良い。 Here, attachment and fixation of the movable coaxial cable 20 will be described.
The F-type plug seat 31 is disposed on one end side of the shaft body 30 so that the center conductor 31a is collinear with the axis of the shaft body 30, and the center conductor 31a is inward of the housing portion 36. Protruding. At the same time, a projecting piece 31 b formed by projecting a part of the outer conductor of the connection terminal 31 is also disposed so as to project into the storage portion 36.
First, the center conductor and the outer conductor processed on the free end side of the movable coaxial cable 20 are fixed to the center conductor 31a and the protruding piece 31b by a known method.
In order to introduce the coaxial cable 21 from the storage portion 36 to the outside of the shaft body 30 at an arbitrary position on the contact surface between the shaft body lid body 34 and the shaft body body 35. A lid-side introduction groove 38 and a body-side introduction groove 39 are formed. The coaxial cable 21 is disposed along both of the grooves, and the lid body 34 and the body 35 are assembled to each other. It is comprised so that the cable 21 may be clamped. Further, a predetermined number of locking claws 38a and 39a are projected on the inner side of the introduction grooves 38 and 39 so as to be at arbitrary positions that do not face each other in the inner direction, and the coaxial cable is pulled out or pushed in. The coaxial cable 21 is firmly clamped against the drag force, and the connection point with the connection terminal 31 is applied with a force so as not to be damaged .
Further, when the shaft body is formed of a synthetic resin material, a shield case formed of a metal material accommodated in the accommodating portion 36 is accommodated, and the central conductor of the coaxial cable 21 is accommodated in the shield case. And the central conductor 31a of the connection terminal may be connected to reduce interference caused by external radio waves.

このようにして軸体３０に取付けられた同軸ケーブル２０は，軸体３０を回転操作させることによって，軸体３０の外周面に巻取りされるのである。
次の組付け手順としては，この軸体２０の枢着軸４０を，ケース本体１２の貫通孔１２ａに貫通させると共に，前記同軸ケーブル２１をケース本体１２に形成した切欠部８に挿通させる。次に，接続端子３１の方向から，前記ケース蓋体１３を前記接続端子３１にケース蓋体１３の貫通孔１３ａが貫通するように取付けると共に，ケース蓋体１３とケース本体１２とを組み付けることによって，本発明の巻取り式同軸ケーブル１が形成される。
尚，軸体の周径は少なくとも同軸ケーブルの最小曲げ径より等しいかやや大きくなるように形成されるものであり，両側壁の軸体周面からの寸法は，所定寸法に形成された同軸ケーブルを巻きつけたときの寸法と等しいかやや大きくなるように形成される。
The coaxial cable 20 thus attached to the shaft body 30 is wound around the outer peripheral surface of the shaft body 30 by rotating the shaft body 30.
As a next assembling procedure, the pivot shaft 40 of the shaft body 20 is passed through the through hole 12a of the case body 12, and the coaxial cable 21 is inserted into the notch 8 formed in the case body 12. Next, from the direction of the connection terminal 31, the case lid 13 is attached to the connection terminal 31 so that the through hole 13 a of the case lid 13 penetrates, and the case lid 13 and the case body 12 are assembled. Thus, the winding coaxial cable 1 of the present invention is formed.
It should be noted that the peripheral diameter of the shaft body is at least equal to or slightly larger than the minimum bending diameter of the coaxial cable, and the dimensions of the both side walls from the shaft body peripheral surface are the coaxial cable formed to a predetermined dimension. It is formed so as to be equal to or slightly larger than the dimension when the is wound.

本発明の実施例においては，接続端子３１は軸体３０に固着されるように構成しているので，該接続端子３１は可動用の同軸ケーブル２０の引き出し，若しくは巻取りの動作と同時に回転してしまう。従って本発明の実施例では，可動用の同軸ケーブル２０を最適な長さに設定した後に，別体の同軸ケーブルを前記接続端子とテレビ受信機のような対象物との間に接続するようにすればよい。図１（ｂ）にはこの接続端子３１が軸体３０と共に回転してしまうといったことの無い例を示したものであり，以下に図４を基に詳細に説明する。
尚，以下の説明では上記実施例と同じ構成を示すものには同一番号を付し特に明記しない限り詳細な説明は省略する。
In the embodiment of the present invention, since the connection terminal 31 is fixed to the shaft body 30, the connection terminal 31 rotates simultaneously with the operation of pulling out or winding the movable coaxial cable 20. End up. Therefore, in the embodiment of the present invention, after the movable coaxial cable 20 is set to an optimum length, a separate coaxial cable is connected between the connection terminal and an object such as a television receiver. do it. FIG. 1B shows an example in which the connection terminal 31 does not rotate together with the shaft body 30, and will be described in detail below with reference to FIG.
In the following description, the same components as those in the above embodiment are denoted by the same reference numerals, and detailed description is omitted unless otherwise specified.

この実施例では，例えば前記接続端子３１に，一方がＦ型プラグ４１ｃで他方がＦ型接栓座４１ｂとからなるアダプター４１を備えさせたものである。
このアダプター４１の中央部には鍔部４１ａが形成されている。この鍔部４１ａは小判型若しくは六角形等の形状となるように形成されており，当該鍔部４１ａの外径形状に対応させた，ケース蓋体１３に形成された凹部１３ｂと係合させることのよって，アダプター４１はケース蓋体に対して，周方向の回転と軸線方向の移動を制限されることになる。
一方，アダプター４１のＦ型プラグ４１ｃ部分は，詳細は図示されていないが，その内周面にバネ材からなる摺動部材が備えさせてある。これによってアダプター４１のＦ型プラグ部４１ｃは，軸体３０に固着された接続端子３１に周方向に回転自在となるように摺動固着されることになると共に，前記摺動部材によって回転動作時においても高周波特性が維持されるのである。
このようにして，軸体３０が回転しても，アダプター４１は回転することが無いので，別に用意された同軸ケーブルを前記接続端子３１とテレビ受信機のような接続対象物との間に接続してから，可動用の同軸ケーブル２０を最適な長さに設定すればよく，更に取扱性のよいものが提供できるのである。 In this embodiment, for example, the connection terminal 31 is provided with an adapter 41 having one F-type plug 41c and the other an F-type plug seat 41b.
A flange 41 a is formed at the center of the adapter 41. The flange 41a is formed in a shape such as an oval shape or a hexagon, and is engaged with a recess 13b formed in the case lid 13 corresponding to the outer diameter shape of the flange 41a. Therefore, the adapter 41 is restricted from rotating in the circumferential direction and moving in the axial direction with respect to the case lid.
On the other hand, the F-type plug 41c portion of the adapter 41 is not shown in detail, but a sliding member made of a spring material is provided on the inner peripheral surface thereof. As a result, the F-type plug portion 41c of the adapter 41 is slidably fixed to the connection terminal 31 fixed to the shaft body 30 so as to be rotatable in the circumferential direction, and is rotated by the sliding member. In this case, the high frequency characteristics are maintained.
In this way, even if the shaft body 30 rotates, the adapter 41 does not rotate, so a separately prepared coaxial cable is connected between the connection terminal 31 and a connection object such as a television receiver. After that, the movable coaxial cable 20 may be set to an optimum length, and a more handleable one can be provided.

尚，この実施例においては，軸体３０に形成された収納部３６に対して軸体の蓋体３４の無い例を示してある。この場合は，軸体本体３５に形成した収容部３６の開口部周縁のスペースに，例えば周知のケーブルクリップ等を用いて同軸ケーブルを固定すればよく，部品材料の削減，製品単価の低減，製品の質量の低減等が可能となる。また外部からの電波によって接続部からの飛び込みが心配される場合は，前記収納部３６収納できるシールドケースを用いれば良い事は言うまでもない。
In this embodiment, an example in which the shaft body lid 34 is not provided for the storage portion 36 formed in the shaft body 30 is shown. In this case, the coaxial cable may be fixed in the space around the opening of the housing portion 36 formed in the shaft body 35 using, for example, a well-known cable clip, etc. It is possible to reduce the mass of Needless to say, a shield case that can be housed in the housing portion 36 may be used when there is concern about jumping in from the connection portion due to external radio waves.

次に本発明の第２の実施形態として図５，６を参照して説明する。尚，以下の説明においても，上記第１の実施形態の巻取り式同軸ケーブルと同様の構成要素については同一符号を付与し，詳細な説明は省略する。
Next, a second embodiment of the present invention will be described with reference to FIGS. In the following description, the same reference numerals are assigned to the same components as those of the winding coaxial cable of the first embodiment, and detailed description thereof is omitted.

この第２の実施形態は，前記可動用の同軸ケーブル２０の他に，固定用の同軸ケーブル２５を具備させたものである。
図５（ａ）に示す実施例では，同軸ケーブル２５は所定長さに形成されたものであり，この同軸ケーブル部２６の両端部には接続端子２７，２８が取付けられている。本願の実施例では特に接続端子２７には，その中央部に形成された鍔部２７ａを備えさせ，当該鍔部２７ａをケース蓋体１３に形成された凹部１３ｂに嵌合させるように組み付けられている。また，Ｆ型プラグ部２７ｃの内周面には，詳細は図示されていないがバネ材からなる摺動部材が備えさせてある。これによってＦ型プラグ部２７ｃはケース蓋体１３によって周方向の回転と軸線方向への移動を制限されることとなり，軸体３０に固着された接続端子３１は周方向に回転自在となるように摺動固着されることになる。また，前記摺動部材によって回転動作時においても高周波特性が維持されるのである。 In the second embodiment, in addition to the movable coaxial cable 20, a fixed coaxial cable 25 is provided.
In the embodiment shown in FIG. 5A, the coaxial cable 25 is formed to have a predetermined length, and connection terminals 27 and 28 are attached to both ends of the coaxial cable portion 26. Particularly in the embodiment of the present application, the connection terminal 27 is provided with a flange portion 27 a formed at the center thereof, and is assembled so that the flange portion 27 a is fitted into the recess 13 b formed in the case lid body 13. Yes. Further, although not shown in detail on the inner peripheral surface of the F-type plug portion 27c, a sliding member made of a spring material is provided. As a result, the F-type plug portion 27c is restricted from rotating in the circumferential direction and moving in the axial direction by the case lid 13, so that the connection terminal 31 fixed to the shaft 30 can be rotated in the circumferential direction. It will be slidably fixed. Further, the sliding member maintains high frequency characteristics even during a rotating operation.

このように本発明の第２の実施例によれば，軸体３０が回転しても，固定用の同軸ケーブル２５は回転することが無いので，この固定用の同軸ケーブル２５の接続端子２８と，可動用の同軸ケーブル２０の接続端子２２を，例えばテレビ端子とテレビ受信機やパーソナルコンピュータのような接続対象物との間に接続するときに，可動用の同軸ケーブル２０を最適な長さに設定すればよく，同軸ケーブルを別途購入する必要も無いので，更に取扱性のよいものが提供できるのである。
Thus, according to the second embodiment of the present invention, even if the shaft body 30 rotates, the fixing coaxial cable 25 does not rotate. When the connection terminal 22 of the movable coaxial cable 20 is connected between, for example, a television terminal and a connection object such as a television receiver or a personal computer, the movable coaxial cable 20 has an optimum length. It is only necessary to set it, and there is no need to purchase a coaxial cable separately.

尚，以下に例示するように，本発明の趣旨を逸脱しない範囲で各部の構成を適宜に変更して実施することも可能である。例えば，ケースは，このケースに形成した挿通孔等を除いて軸体を完全に覆うように形成する必要が無く，一部を開放するように形成してもよい。この場合は，同軸ケーブルを軸体に巻取る際に，同軸ケーブルを軸体に均一に巻取る補正が簡単に行える。
また，例えばケース本体とケース蓋体との係止方法をネジ式のようにすれば，係止を緩めた時に同軸ケーブルの引出しや巻取りが可能となり，係止を締付けた時は，同軸ケーブルの引出しや巻取りが制限されるように，上記実施例にロック機能を備えた構成にすればさらに取扱性に対して優れたものとなる。
また，図１（ｂ）及び図５（ａ）に示すロータリージョイント部分は，軸体に取付けられたＦ型接栓座にＦ型プラグを摺動固着する方法を示したが，この接合部分はＦ型プラグとＦ型接栓座を用いなくても，軸体の回転動作に対して固定用の同軸ケーブルが捩れてしまわない構造であり，接続部の特性を維持できるものであれば，図５（ｂ）に示すように特にＦ型にする必要はない。
更に，本発明においては可動用の同軸ケーブルの収納操作は，操作ツマミ５０を回転操作して行う例を示したが，例えば収納側壁３２にバネ材（請求項６に記載の発条に相当）を具備させることによって，該バネ材によって自動的に巻取り可能なように構成してもよい。自働巻取り式にすれば，操作ツマミは必要でないので，該操作ツマミを取付けるための枢着軸を軸体に形成する替わりに，ケース本体の内側に枢着軸を一体に形成して，該枢着軸を軸体の端部に設けた枢着穴に挿入するように構成するようにしてもよい。この場合はケースの外壁に突出する部分が少なくなるので，外形が小さくでき，すっきりとしたデザインとなる等の効果が得られるのである。
更に加えて，本発明の構造を分配器や分岐器等に取り入れてもよい事は言うまでもなく，また，収納部に同軸ケーブルの損失を補正する増幅手段を収納するようにしてもよい等，本発明は上記実施の形態に限定されるものでないことは言うまでもない。 In addition, as illustrated below, the configuration of each part can be changed as appropriate without departing from the spirit of the present invention. For example, the case does not need to be formed so as to completely cover the shaft body except for an insertion hole formed in the case, and may be formed so as to partially open. In this case, when winding the coaxial cable to the shaft member, uniformly winding take correction can be performed easily coaxial cables to the shaft member.
In addition, for example, if the locking method of the case body and the case lid is screw type, the coaxial cable can be pulled out and wound when the locking is loosened, and when the locking is tightened, the coaxial cable If the configuration of the above embodiment is provided with a lock function so that the drawing and winding are restricted, the handling property is further improved.
In addition, the rotary joint portion shown in FIGS. 1 (b) and 5 (a) showed a method of slidingly fixing the F-type plug to the F-type plug seat attached to the shaft body. Even if the F-type plug and F-type connector seat are not used, the structure is such that the fixing coaxial cable is not twisted with respect to the rotational movement of the shaft body, and can maintain the characteristics of the connection. As shown in FIG. 5 (b), it is not particularly necessary to use the F type.
Further, in the present invention, an example in which the storing operation of the movable coaxial cable is performed by rotating the operation knob 50 is shown. For example, a spring material (corresponding to the strip according to claim 6) is provided on the storing side wall 32. By providing it, you may comprise so that it can wind up automatically with this spring material. If the self-winding type is used, an operation knob is not required. Instead of forming a pivot shaft for mounting the operation knob on the shaft body, a pivot shaft is integrally formed inside the case body. The pivot shaft may be configured to be inserted into a pivot hole provided at the end of the shaft body. In this case, since the protruding portion on the outer wall of the case is reduced, the outer shape can be reduced, and an effect such as a neat design can be obtained.
In addition, it goes without saying that the structure of the present invention may be incorporated in a distributor, a branching device, etc., and that the amplifying means for correcting the loss of the coaxial cable may be housed in the housing portion. It goes without saying that the invention is not limited to the above-described embodiment.
