請求項１の発明によれば，本体の内部には伝送信号を分配するための回路手段を有し，本体の外壁には伝送経路を介して前記回路手段と他の機器に接続するための複数の同軸接栓座を有する分岐及び分配器において，
前記本体は，該本体の１つの面に前記同軸接栓座の軸線が並行配置されるように同じ方向を向けて突出するように同軸接栓座を備え，
前記本体における，前記同軸接栓座の配列方向に位置する両側面と，前記同軸接栓座の最も外側に配設された同軸接栓座との間における前記本体の両端部には，内周面に段部が設けられ，少なくとも，該段部に連設して前記止着ねじの挿脱方向側に形成された開口部から段部にかけて配設される大径部と，前記段部から前記設置すべき面に設置するための設置面側に形成された開口部にかけて配設される小径部とから構成された，前記本体が前記同軸接栓座の突出方向を前記本体を設置すべき面に止着ねじを用いて並行配置して固定するために夫々対設された止着ねじ挿通用の第１及び第３の挿通孔と，前記同軸接栓座の突出方向を前記本体を設置すべき面に止着ねじを用いて直交配置して固定するために対設された止着ねじ挿通用の第２の挿通孔を備え，前記第１の挿通孔と前記第３の挿通孔は夫々の中心軸線を並列配置して，前記大径部と前記小径部の配列方向を対向するように配設し、前記同軸接栓座の最も外側に配設された一方の同軸接栓座と，該同軸接栓座と隣接する同軸接栓座との間の周面に識別部を備えさせたので，
前記本体が前記同軸接栓座の突出方向を前記本体を設置すべき面に止着ねじを用いて並行配置して固定したり，前記同軸接栓座の突出方向を前記本体を設置すべき面に止着ねじを用いて直交配置して固定したりすることによって，設置場所の状態によって取り付け方向を選択的に選ぶことができ，例えば建築物の壁面の近傍であっても同軸接栓座に接続された同軸ケーブルの突出方向を壁面の反対方向にするように配線ができるし，ＡＶラックのように上下方向の間隔が狭く仕切られたような狭い場所であっても，壁面に対して直交する方向に同軸ケーブルが突出するように設置することによってすることによって，同軸ケーブルを無理な曲げ半径で配線することもなく配線が容易に且つ電気的特性に影響の無いように配線できる。更には，前記第１及び第２及び第３の挿通孔を相互に重合するように本体の両端部に効率よく配設したので，本体の長手方向の寸法を短く形成でき，延いては分岐及び分配器を小型化することができる。 According to the first aspect of the present invention, the main body has circuit means for distributing the transmission signal, and the outer wall of the main body has a plurality of terminals for connecting to the circuit means and other devices via the transmission path. In branch and distributor with coaxial connector seat
The main body includes a coaxial plug seat so as to protrude in the same direction so that the axis of the coaxial plug seat is arranged in parallel on one surface of the main body,
The both ends of the main body between the both side surfaces of the main body located in the arrangement direction of the coaxial plug seats and the coaxial plug seat disposed on the outermost side of the coaxial plug seats have inner peripheries. A step is provided on the surface, and at least a large-diameter portion arranged from the opening to the step formed in the insertion / removal direction side of the set screw and connected to the step, and from the step The main body should be installed so that the coaxial connector seat protrudes in the protruding direction of the small-diameter portion disposed over the opening formed on the installation surface side for installation on the surface to be installed. The main body is installed with first and third insertion holes for insertion of fixing screws, which are arranged to be fixed in parallel on the surface using fixing screws, and the protruding direction of the coaxial connector seat. A second fixing screw for inserting a fixing screw, which is arranged to be orthogonally fixed to the surface to be fixed by using a fixing screw. Includes a hole, wherein the first insertion hole third insertion hole is arranged in parallel a central axis of the respective disposed so as to face the arrangement direction of the large diameter portion the smaller diameter portion, said and outermost on disposed the one coaxial contact plug seat of the coaxial contact plug seat, so was provided with an identification part on the peripheral surface between the coaxial contact plug seat adjacent to the coaxial contact plug seat,
The main body fixes the protruding direction of the coaxial connector seat parallel to the surface on which the main body is to be installed using a fastening screw, or the protruding direction of the coaxial connector seat is the surface on which the main body is to be installed. The mounting direction can be selectively selected according to the condition of the installation location, for example, by using a coaxial screw seat even in the vicinity of the wall of the building. Wiring can be performed so that the protruding direction of the connected coaxial cable is opposite to the wall surface, and even in a narrow place where the vertical space is narrowly partitioned, such as an AV rack, it is orthogonal to the wall surface. By installing the coaxial cable so that it protrudes in the direction in which the coaxial cable protrudes, the coaxial cable can be easily wired without undue bending radius and without affecting the electrical characteristics. Furthermore, since the first, second and third insertion holes are efficiently arranged at both ends of the main body so as to overlap each other, the length of the main body in the longitudinal direction can be shortened, and the branch and The distributor can be reduced in size.

更に前記同軸接栓座の最も外側に配設された一方の同軸接栓座と，該同軸接栓座と隣接する同軸接栓座との間の位置に，識別部を備えさせたによって，設置の場所が暗い場所であっても狭い場所であっても，また，同軸接栓座の突出方向が取付面に並行配列した状態であっても，取付面に直交配置した状態であっても，常に同軸接栓座の最も外側に配設された一方の同軸接栓座の位置が判断できる。即ち，例えば２分配器，３分配器，４分配器に対して中央に位置する同軸接栓座を入力端子とすると，２分配器，４分配器を構成する本体の金型が違ったとしても出力端子が前記入力端子に対して対称位置に配設されることから，入力端子の識別が容易となるのであるが，３分配器に対しては金型の問題から前記４分配器用の本体を利用して構成することになり，この結果，出力端子の配列が出力端子に対して対象でなくなるので，入力端子の識別が難しくなるのであるが，本願の如く最も外側に配設された一方の同軸接栓座を入力端子と定め，その同軸接栓座と隣接する同軸接栓座との間に上述のような識別部を備えさせることによって，何れの分配器であっても入力端子の位置は全機種共通とすることができ，視認が容易でない取付状態であっても取付けの容易性を損なわない分岐及び分配器を提供できるのである。 Further, an identification portion is provided at a position between one coaxial connector seat disposed on the outermost side of the coaxial connector seat and the coaxial connector seat adjacent to the coaxial connector seat. Whether it is a dark place or a narrow place, whether the protruding direction of the coaxial connector seat is parallel to the mounting surface, The position of one coaxial connector seat disposed on the outermost side of the coaxial connector seat can always be determined. That is, for example, if the coaxial connector seat located in the center with respect to the 2-distributor, 3-distributor, and 4-distributor is used as the input terminal, even if the die of the main body constituting the 2-distributor, 4-distributor differs. Since the output terminal is arranged in a symmetrical position with respect to the input terminal, the input terminal can be easily identified. However, for the 3-distributor, the main body for the 4-distributor is installed due to the problem of the mold. As a result, since the arrangement of the output terminals is not targeted with respect to the output terminals, it becomes difficult to identify the input terminals, but one of the outermost terminals as in the present application is arranged. By defining the coaxial connector seat as an input terminal and providing the identification part as described above between the coaxial connector seat and the adjacent coaxial connector seat, the position of the input terminal can be determined in any distributor. Can be common to all models and is not easily visible We can provide a branched and distributor does not impair the ease of mounting even.

図に示す１は本発明に係る分岐及び分配器であり，以下には説明を容易とするため特に明記しない限り分配器についての詳細を記載する。
この図１，２において，１０は本体であり，例えばアルミダイカストを金型で成形したものである。この本体１０は該本体１０の一端（本図によれば底面１１）を開口した箱状に形成されており。この開口部１１には，金属製材料（例えばアルミ材）を用いた蓋体９を圧入等で固着する構造として，蓋体９と本体１０とを強固に固着すると共に，外部からの妨害波等の侵入を低減するように構成されている。この本体１０の内部には分配回路が形成されたプリント基板５等からなる回路手段が収納されている。 Reference numeral 1 shown in the figure denotes a branching and distributing device according to the present invention. In order to facilitate the explanation, details of the distributing device will be described unless otherwise specified.
In FIGS. 1 and 2, reference numeral 10 denotes a main body, for example, an aluminum die cast formed by a mold. The main body 10 is formed in a box shape in which one end of the main body 10 (the bottom surface 11 in this figure) is opened. The opening 11 has a structure in which a lid 9 made of a metal material (for example, aluminum material) is fixed by press-fitting or the like, so that the lid 9 and the main body 10 are firmly fixed, and an interference wave from the outside, etc. It is configured to reduce intrusion. The main body 10 contains circuit means including a printed circuit board 5 on which a distribution circuit is formed.

また，この図に示す実施例では本体１０の側面１２（図１における上面）には，前記本体１０と一体に成形されたＦ型接栓座２０ａから２０ｅが，該接栓座の軸線が側面１２と直交する方向に突設されており，前記回路手段５と他の機器に接続できるように構成されている。尚，前記接栓座２０は本体１０の側面１２に圧着やカシメ等の手段によって固着しても良い。
このように同軸接栓座２０が全て同一方向を向いて形成されているので，金型構造が簡単となり，延いては製品のコストを安くすることができる。 Further, in the embodiment shown in this figure, on the side surface 12 (upper surface in FIG. 1) of the main body 10, there are F-type plug seats 20a to 20e formed integrally with the main body 10, and the axis of the plug seat is a side surface. 12 is formed so as to be connected to the circuit means 5 and other devices. The connecting seat 20 may be fixed to the side surface 12 of the main body 10 by means such as crimping or caulking.
As described above, since the coaxial connector seats 20 are all formed in the same direction, the mold structure is simplified, and the cost of the product can be reduced.

前記本体１０における，前記同軸接栓座２０の配列方向に位置する両側の側面１３，１３と，前記同軸接栓座２０の最も外側に配設された同軸接栓座２０ａ，２０ｅと，の間における前記本体１０の両端部８，８には，前記本体１０が前記同軸接栓座２０の突出方向を前記本体１０を設置すべき面４０に並行配置させ，止着ねじを用いて固定するための夫々対設された止着ねじ挿通用の第１の挿通孔２１及び第３の挿通孔２３と，前記同軸接栓座２０の突出方向を前記本体１０を設置すべき面４０に直交配置させ，止着ねじを用いて固定するための対設された止着ねじ挿通用に対設された第２の挿通孔２２が形成されている。
これらの挿通孔の実施例は図２によく示されるように，前記第１の挿通孔２１の内周面には段部２１ａが設けられ，少なくとも，該段部２１ａに連設して前記止着ねじの挿脱方向側の側面１４に形成された開口部１４ａから段部２１ａにかけて配設される大径部４１ａと，前記段部２１ａから前記設置すべき面に設置するための設置面１５側に形成された開口部１５ａにかけて配設される小径部４１ｂとから構成されている。
また，前記第３の挿通孔２３は，内周面に段部２３ａが設けられ，少なくとも，該段部２３ａに連設して前記止着ねじの挿脱方向側の側面１５に形成された開口部１５ｂから段部２３ａにかけて配設される大径部４３ａと，前記段部２３ａから前記設置すべき面に設置するための設置面１４側に形成された開口部１４ｂにかけて配設される小径部４３ｂとから構成されており，前記第１の挿通孔２１と第３の挿通孔２３における大径部４１ａと４３ａ，小径部４１ｂと４３ｂとの配列方向が相互に対向するように夫々の中心軸線を並列配置させてある。 Between the side surfaces 13, 13 on both sides of the main body 10 positioned in the arrangement direction of the coaxial connector seats 20, and the coaxial connector seats 20 a, 20 e disposed on the outermost side of the coaxial connector seat 20. The main body 10 is arranged at both end portions 8 and 8 of the main body 10 in such a manner that the protruding direction of the coaxial connector seat 20 is arranged in parallel with the surface 40 on which the main body 10 is to be installed, and is fixed using fastening screws. The first insertion hole 21 and the third insertion hole 23 for inserting the fixing screws, and the protruding direction of the coaxial connector seat 20 are arranged orthogonally to the surface 40 on which the main body 10 is to be installed. , A second insertion hole 22 is formed so as to be provided for insertion of a fixed set screw for fixing with a set screw.
As shown in FIG. 2, in the embodiment of these insertion holes, a step portion 21a is provided on the inner peripheral surface of the first insertion hole 21, and at least the step portion 21a is connected to the stop portion. A large-diameter portion 41a disposed from the opening portion 14a to the step portion 21a formed on the side surface 14 on the insertion / removal direction side of the screw, and an installation surface 15 for installation on the surface to be installed from the step portion 21a. And a small-diameter portion 41b disposed over the opening 15a formed on the side.
Further, the third insertion hole 23 is provided with a step portion 23a on the inner peripheral surface, and at least an opening formed on the side surface 15 on the insertion / removal direction side of the fixing screw so as to be connected to the step portion 23a. A large-diameter portion 43a disposed from the portion 15b to the step portion 23a, and a small-diameter portion disposed from the step portion 23a to the opening portion 14b formed on the installation surface 14 side for installation on the surface to be installed. 43b, and the central axes of the first insertion hole 21 and the third insertion hole 23 so that the arrangement directions of the large diameter portions 41a and 43a and the small diameter portions 41b and 43b face each other. Are arranged in parallel.

更に，前記第２の挿通孔２２は，内周面に段部２２ａが設けられ，少なくとも，該段部２２ａに連設して前記止着ねじの挿脱方向側の側面１２に形成された開口部１２ａから段部２２ａにかけて配設される大径部４２ａと，前記段部２２ａから前記設置すべき面に設置するための設置面１１側に形成された開口部１１ａにかけて配設される小径部４２ｂとから構成されており，この第２の挿通孔２２の中心軸線と前記第１の挿通孔２１及び前記第３の挿通孔２３の中心軸線とは直交配置されると共に，前記第１及び第２及び第３の挿通孔の中心軸線は，前記両端部８における前記同軸接栓座の配列方向に直交する平面上に配設するように形成されている。
このように前記挿通孔を形成することによって，該挿通孔を形成するのに必要なスペースを最少にすることができるので，本体１０の長手方向の寸法を小さくすることができるのである。
加えて，本願の実施例に示すように，例えば前記大径部４１ａ，４２ａ，４３ａの寸法は前記止着ねじのねじ頭の径よりやや大きく形成し，前記小径部４１ｂ，４２ｂ，４３ｂは前記ねじ頭の径より小さく前記止着ねじのねじ部を挿通させるように形成し，前記挿通孔に止着ねじを挿通して該止着ねじを取付面に螺着することによって，本体を取付面に固定するように構成すれば，前記止着ねじの寸法を短くできるし，止着ねじが本体周面から突出しないので美観を損なうことがないのである。
尚，前記小径部の内面に突片を形成しておいて，該突片に前記止着ねじを予め（出荷の状態で）螺着された状態にあるようにすれば利便性が更に良くなる。 Furthermore, the second insertion hole 22 is provided with a step portion 22a on the inner peripheral surface, and at least an opening formed on the side surface 12 on the insertion / removal direction side of the set screw in a continuous manner with the step portion 22a. A large diameter portion 42a disposed from the portion 12a to the step portion 22a, and a small diameter portion disposed from the step portion 22a to the opening portion 11a formed on the installation surface 11 side for installation on the surface to be installed. 42b, the central axis of the second insertion hole 22 and the central axes of the first insertion hole 21 and the third insertion hole 23 are orthogonally arranged, and the first and first The central axes of the second and third insertion holes are formed so as to be arranged on a plane orthogonal to the arrangement direction of the coaxial connector seats at the both end portions 8.
By forming the insertion hole in this way, the space required to form the insertion hole can be minimized, and the longitudinal dimension of the main body 10 can be reduced.
In addition, as shown in the embodiment of the present application, for example, the dimensions of the large diameter portions 41a, 42a, 43a are formed slightly larger than the diameter of the screw head of the set screw, and the small diameter portions 41b, 42b, 43b are The screw body of the set screw is formed so as to be inserted smaller than the diameter of the screw head, the set screw is inserted into the insertion hole, and the set screw is screwed to the mount surface. If the fixing screw is configured to be fixed to the fixing screw, the size of the fixing screw can be shortened, and the fixing screw does not protrude from the peripheral surface of the main body, so that the appearance is not impaired.
In addition, if a projecting piece is formed on the inner surface of the small-diameter portion and the fixing screw is pre-screwed (in the shipping state) to the projecting piece, the convenience is further improved. .

更に加えて，このような挿通孔内部の段部を止着ねじで締め付けるように構成した場合は，前記段部と取付面との間に介在する本体部分の構造体が前記止着ねじの締め付けに対して充分な強度が得られなければならない。そこで本願の実施例においては，前記第１の挿通孔２１と前記第２の挿通孔２２は夫々の中心軸線を直交配置して，該中心軸線の交点が前記第１の挿通孔２１の大径部４１ａと前記第３の挿通孔２３の大径部４３ａに位置するように，挿通孔を重合し且つ同一平面上に配設する用に構成することによって，前記本体１０が前記同軸接栓座２０の突出方向を前記本体１０を設置すべき面に止着ねじを用いて並行配置して固定した場合であっても，前記同軸接栓座２０の突出方向を前記本体１０を設置すべき面に止着ねじを用いて直交配置して固定した場合であっても，段部に止着ねじを取付けた時の挿通孔の強度が得られる配置となるので，本体１０の取付面に対する取付強度を強く保てる分配器１を提供できるのである。 In addition, when the step inside the insertion hole is tightened with a set screw, the structure of the main body part interposed between the step and the mounting surface is tightened with the set screw. Sufficient strength must be obtained. Therefore, in the embodiment of the present application, the first insertion hole 21 and the second insertion hole 22 are arranged so that the central axes thereof are orthogonally arranged, and the intersection of the central axes is the large diameter of the first insertion hole 21. By arranging the insertion holes so as to overlap and be arranged on the same plane so as to be positioned at the large diameter portion 43a of the portion 41a and the third insertion hole 23, the main body 10 is connected to the coaxial plug seat. Even when the protruding direction of 20 is fixed to the surface on which the main body 10 is to be installed in parallel by using a fastening screw, the protruding direction of the coaxial connector seat 20 is the surface on which the main body 10 is to be installed. Even if the fixing screw is used to fix the fixing screw at right angles, the strength of the insertion hole can be obtained when the fixing screw is attached to the stepped portion. Can be provided.

次に識別部３について説明する。本願の実施例では前記同軸接栓座２０の最も外側に配設された一方の同軸接栓座２０ａと，該同軸接栓座２０ａと隣接する同軸接栓座２０ｂとの間の位置であって，同軸接栓座２０の配列方向に直交する平面上となる位置の前記本体１０の全周面にわたって一体的に形成された凹部から成る。この識別部３によれば，設置の場所が暗い場所であっても狭い場所であっても，また，同軸接栓座２０の突出方向が取付面に並行配列した状態であっても，取付面に直交配置した状態であっても，常に同軸接栓座２０の最も外側に配設された一方の同軸接栓座２０ａの位置を，特別に探ることなく指先で触れるだけで一瞬に判断できるのである。即ち，例えば２分配器，３分配器，４分配器等に対して中央に位置する同軸接栓座２０ａを入力端子とすると，２分配器，４分配器を構成する本体の金型が違ったとしても出力端子が前記入力端子に対して対称位置に配設されることから，入力端子の識別が容易となるのである。ところが３分配器を作る場合，３分配器は前記４分配器用の本体を利用して構成することが金型の制作費の削減の面からよい。この結果，出力端子の配列が出力端子に対して対称でなくなるので，入力端子の識別が難しくなるのである。そこで図３に良く示されるように，本願の如く最も外側に配設された一方の同軸接栓座２０ａを入力端子と定め，その同軸接栓座２０ａと隣接する同軸接栓座２０ｂとの間に上述のような識別部３を備えさせることによって，何れの分岐器及び分配器１であっても入力端子の位置は全機種共通とすることができ，且つ，視認が容易でない取付状態であっても，取付けの方向がどちらを向いていても，識別の容易性を損なわない分岐及び分配器１を提供できるのである。
尚，分岐器の場合は最も外側にある他方の同軸接栓座を出力端子と規定すれば同様の効果が得られる。 Next, the identification unit 3 will be described. In the embodiment of the present application, it is a position between one coaxial connector seat 20a disposed on the outermost side of the coaxial connector seat 20 and the coaxial connector seat 20b adjacent to the coaxial connector seat 20a. , And a concave portion integrally formed over the entire peripheral surface of the main body 10 at a position on a plane orthogonal to the arrangement direction of the coaxial connector seats 20. According to the identification unit 3, whether the installation place is a dark place or a narrow place, and the protruding direction of the coaxial connector seat 20 is arranged in parallel with the attachment face, the attachment face Even in the state of being arranged orthogonally to each other, the position of one coaxial connector seat 20a disposed on the outermost side of the coaxial connector seat 20 can always be determined instantly by simply touching it with a fingertip without searching for it. is there. That is, for example, when the coaxial connector seat 20a located in the center with respect to the 2-distributor, 3-distributor, 4-distributor, etc. is used as the input terminal, the mold of the main body constituting the 2-distributor, 4-distributor is different. However, since the output terminal is disposed at a symmetrical position with respect to the input terminal, the input terminal can be easily identified. However, in the case of making a 3-distributor, it is preferable to configure the 3-distributor using the main body for the 4-distributor from the viewpoint of reducing the production cost of the mold. As a result, the arrangement of the output terminals is no longer symmetric with respect to the output terminals, making it difficult to identify the input terminals. Therefore, as shown well in FIG. 3, one coaxial connector seat 20a arranged on the outermost side as in the present application is defined as an input terminal, and between the coaxial connector seat 20a and the adjacent coaxial connector seat 20b. By providing the identification unit 3 as described above, the position of the input terminal can be made common to all models regardless of the branching device and the distributor 1, and the mounting state is not easy to see. However, it is possible to provide the branching and distributing device 1 that does not impair the ease of identification, regardless of which direction the mounting is directed.
In the case of a branching device, the same effect can be obtained by defining the other coaxial connecting seat on the outermost side as an output terminal.

更に，化粧ケース２の前記接栓座２０の周縁部には，該接栓座に対して同心形状と成るように本体１０の内部方向に凹ませた凹部２５を形成することによって，該凹部２５に，前記接栓座２０に取り付けられる図示されていないコネクタ栓等に備えた前記接栓座を収納するための筒状に形成された接栓座収容部を収納させることによって，コネクタ栓が本体１０から突出する寸法を小さくするように構成することによって省スペース化が図れるのである。 4 and 5 show different embodiments of the distributor 1 of the present invention.
