Description

本発明は、アンテナを筐体に接続する技術に関する。   The present invention relates to a technique for connecting an antenna to a casing.

デジタルTV放送の普及に伴い、TV局の番組制作現場では非圧縮のハイビジョン信号の伝送が可能な無線システムに対する要望が高まっている。発明者らは大容量の無線回線に対する要望にこたえるべく、ミリ波を使用した大容量無線技術の開発を行ってきた。   With the spread of digital TV broadcasting, there is an increasing demand for a wireless system capable of transmitting an uncompressed high-definition signal at a TV station program production site. The inventors have developed a large-capacity radio technology using millimeter waves in order to meet the demand for a large-capacity radio link.

TV局の中継番組においては、現場に到着してから中継が可能になるまでの時間を可能な限り短くしたいという要望がある。ところが、従来のミリ波無線機では、無線信号を発生するヘッド部にアンテナを取り付け、さらに、ヘッド部筐体を開けてアンテナにモジュールを取り付ける必要があり、簡易にミリ波無線機を組み立てることができなかった。これは、ミリ波信号を伝送する導波管のサイズが2mm×1mmと非常に小さいため、信号伝送部の接続に厳しい精度が要求されるからである。   In a relay program of a TV station, there is a demand for shortening the time from the arrival at the site until the relay becomes possible as much as possible. However, in conventional millimeter-wave radios, it is necessary to attach an antenna to the head unit that generates radio signals, open the head unit housing, and attach a module to the antenna. could not. This is because the size of the waveguide for transmitting the millimeter wave signal is very small, 2 mm × 1 mm, and thus strict accuracy is required for the connection of the signal transmission unit.

そこで、図5に示すように、ヘッド部とアンテナの接続にバイヨネット機構を導入し、従来よりも簡便にアンテナを取り付けることを可能とした(非特許文献1参照)。   Therefore, as shown in FIG. 5, a bayonet mechanism is introduced to connect the head portion and the antenna, and the antenna can be attached more easily than in the past (see Non-Patent Document 1).

図5に示すアンテナ接続部はヘッド部とアンテナに分けられ、ヘッド部の接続部100およびアンテナの接続部200それぞれに、方形導波管101,201が形成されている。方形導波管101,201を正確に接続するために、ヘッド部の接続部100に位置合わせ用穴102、アンテナの接続部200に位置合わせ用ピン202を配置している。位置合わせ用穴102に位置合わせ用ピン202を差し込むことで方形導波管101,201が接続される。方形導波管101,201を接続した後、羽根203を回して接続部100,200を固定する。   The antenna connecting portion shown in FIG. 5 is divided into a head portion and an antenna, and rectangular waveguides 101 and 201 are formed in the connecting portion 100 of the head portion and the connecting portion 200 of the antenna, respectively. In order to accurately connect the rectangular waveguides 101 and 201, an alignment hole 102 is disposed in the connection portion 100 of the head portion, and an alignment pin 202 is disposed in the connection portion 200 of the antenna. The rectangular waveguides 101 and 201 are connected by inserting the alignment pins 202 into the alignment holes 102. After the rectangular waveguides 101 and 201 are connected, the blades 203 are turned to fix the connection portions 100 and 200.

しかしながら、図5に示すアンテナの接続方式では、微細な方形導波管101,201の位置合わせを行うために、精密な加工精度がもとめられるという問題があった。また、位置合わせ用ピン202を位置合わせ用穴102に入れるためには、角度や位置を精度よく合わせる必要があり、アンテナの取り付けに時間がかかるという問題があった。さらに、方形導波管101,201同士を接合した場合、ピンと穴の遊びの関係上、方形導波管101,201の傾きにずれが生じる可能性があるという問題があった。方形導波管101,201の傾きにずれが生じると、伝送特性が大幅に劣化してしまう。   However, the antenna connection method shown in FIG. 5 has a problem that precise processing accuracy can be obtained in order to align the fine rectangular waveguides 101 and 201. In addition, in order to put the positioning pin 202 into the positioning hole 102, it is necessary to accurately match the angle and position, and there is a problem that it takes time to mount the antenna. Furthermore, when the rectangular waveguides 101 and 201 are joined together, there is a problem that the inclination of the rectangular waveguides 101 and 201 may be shifted due to the play between the pins and the holes. If the inclination of the rectangular waveguides 101 and 201 is deviated, the transmission characteristics are greatly deteriorated.

本発明は、上記に鑑みてなされたものであり、導波管入出力を有するアンテナを筐体に簡易に取り付けることを目的とする。   The present invention has been made in view of the above, and an object thereof is to easily attach an antenna having a waveguide input / output to a housing.

本発明に係る無線装置は、アンテナを筐体に取り付けて使用する無線装置であって、アンテナは、円柱形の中心軸に沿って円形導波管を形成した接続手段を有し、筐体は、方形導波管を入出力とする信号モジュールと、一端に方形開口部を有し、他端に円形開口部を有する導波管を備え、信号モジュールの入出力に方形開口部を接続した円形−方形導波管変換手段と、接続手段の形状に合わせた円柱形の凹部を備え、当該凹部の底面の中心に円形開口部を露出させた支持手段と、を有することを特徴とする。   A wireless device according to the present invention is a wireless device that uses an antenna attached to a housing, and the antenna has connection means in which a circular waveguide is formed along a cylindrical central axis. A signal module having a rectangular waveguide as input and output, and a waveguide having a square opening at one end and a circular opening at the other end, and a square opening connected to the input and output of the signal module A rectangular waveguide conversion unit; and a support unit that includes a cylindrical recess adapted to the shape of the connection unit and that has a circular opening exposed at the center of the bottom surface of the recess.

以下、本発明の実施の形態について図面を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[第1の実施の形態]
図1は、第1の実施の形態における無線装置のアンテナ接続部の構成を示す側面図である。なお、同図では、無線装置の筐体10とアンテナ20を分離し、筐体10とアンテナ20の一部を断面で示している。
[First Embodiment]
FIG. 1 is a side view illustrating a configuration of an antenna connection unit of a wireless device according to the first embodiment. In the figure, the casing 10 and the antenna 20 of the wireless device are separated, and a part of the casing 10 and the antenna 20 are shown in cross section.

アンテナ20は、主反射鏡21、副反射鏡22、および1次放射器23を備えたカセグレンアンテナであり、アンテナ20を筐体10に取り付けるための接続部24を備える。接続部24は円柱形であり、側面に雄ねじ部241を有し、接続部24の中心軸に沿って一方の円形面から他方の円形面へ通ずる円形導波管242を有する。円形導波管242の一端は1次放射器23に接続される。他端は接続部24の円形面から露出し、アンテナ20が筐体10に取り付けられたときに筐体10の導波管に接続される。   The antenna 20 is a Cassegrain antenna that includes a main reflecting mirror 21, a sub-reflecting mirror 22, and a primary radiator 23, and includes a connection portion 24 for attaching the antenna 20 to the housing 10. The connection portion 24 has a cylindrical shape, has a male screw portion 241 on the side surface, and has a circular waveguide 242 that communicates from one circular surface to the other circular surface along the central axis of the connection portion 24. One end of the circular waveguide 242 is connected to the primary radiator 23. The other end is exposed from the circular surface of the connecting portion 24 and is connected to the waveguide of the housing 10 when the antenna 20 is attached to the housing 10.

筐体10は、内部にミリ波モジュール11と円形−方形導波管変換部12を備え、外部(表面)に支持部13を備える。ミリ波モジュール11は、無線信号を入出力する方形導波管ポート111を備える。円形−方形導波管変換部12は、一端に方形開口部を有し、他端に円形開口部を有する導波管を備える。方形開口部はミリ波モジュール11の方形導波管ポート111に接続され、円形開口部は筐体10外部(表面)へ露出するように配置される。支持部13は、アンテナ20の接続部24を挿入するための円柱形の凹部を有し、凹部の内周には雌ねじ部131が形成される。凹部の円形底面の中心には、筐体10から露出した円形−方形導波管変換部12の円形開口部が配置される。より具体的には、円形開口部は、円形開口部の中心が円柱形の凹部の中心軸に重なるように配置される。   The housing 10 includes a millimeter wave module 11 and a circular-rectangular waveguide conversion unit 12 inside, and a support unit 13 on the outside (surface). The millimeter wave module 11 includes a rectangular waveguide port 111 for inputting and outputting radio signals. The circular-rectangular waveguide converter 12 includes a waveguide having a square opening at one end and a circular opening at the other end. The rectangular opening is connected to the rectangular waveguide port 111 of the millimeter wave module 11, and the circular opening is arranged to be exposed to the outside (surface) of the housing 10. The support portion 13 has a cylindrical recess for inserting the connection portion 24 of the antenna 20, and a female screw portion 131 is formed on the inner periphery of the recess. In the center of the circular bottom surface of the concave portion, a circular opening of the circular-rectangular waveguide converter 12 exposed from the housing 10 is disposed. More specifically, the circular opening is arranged so that the center of the circular opening overlaps the central axis of the cylindrical recess.

図1に示す無線装置は、アンテナ20の接続部24を筐体10の支持部13へねじ込んでアンテナ20を筐体10に取り付ける。これにより、円形−方形導波管変換部12の円形開口部と接続部24の円形導波管242が接続される。   The radio apparatus shown in FIG. 1 attaches the antenna 20 to the housing 10 by screwing the connection portion 24 of the antenna 20 into the support portion 13 of the housing 10. As a result, the circular opening of the circular-rectangular waveguide converter 12 and the circular waveguide 242 of the connecting portion 24 are connected.

通常、ミリ波モジュール11の入出力は方形導波管であるため、アンテナの入出力もそれにあわせて方形導波管となるが、カセグレンアンテナやパラボラアンテナの1次放射器は円形フィードホーンであるため、アンテナ内で円形−方形導波管変換が用いられる。本実施の形態では、筐体10内に円形−方形導波管変換部12を備えることで、筐体10とアンテナ20の接続部分を円形導波管とした。一般に、円形部品の中心に方形の加工をするよりも、円形部品の中心に対し、中心を揃えて円形の穴を開ける加工をするほうが、円形の穴の位置精度が良い。したがって、円柱形の接続部24の中心軸に正確に円形導波管242を設け、支持部13の円柱形の凹部の円形底面の中心に合わせて円形−方形導波管変換部12の円形開口部の中心を配置することで、円形開口部の中心と円形導波管242の中心がずれる問題は回避可能である。また、筐体10とアンテナ20の導波管の接合面が円形であるので、アンテナ20をねじ込む回転方向のずれも問題ない。   Normally, since the input / output of the millimeter wave module 11 is a rectangular waveguide, the input / output of the antenna also becomes a rectangular waveguide accordingly. However, the primary radiator of the Cassegrain antenna or the parabolic antenna is a circular feed horn. Therefore, a circular-rectangular waveguide conversion is used in the antenna. In the present embodiment, the circular-rectangular waveguide converter 12 is provided in the housing 10 so that the connecting portion of the housing 10 and the antenna 20 is a circular waveguide. Generally, the position accuracy of the circular hole is better when the circular hole is formed by aligning the center with respect to the center of the circular part than when the circular part is processed at the center of the circular part. Therefore, the circular waveguide 242 is accurately provided on the central axis of the cylindrical connecting portion 24, and the circular opening of the circular-rectangular waveguide converting portion 12 is aligned with the center of the circular bottom surface of the cylindrical concave portion of the support portion 13. By disposing the center of the part, the problem of the center of the circular opening and the center of the circular waveguide 242 deviating can be avoided. Moreover, since the joint surface of the housing 10 and the waveguide of the antenna 20 is circular, there is no problem in the rotational direction in which the antenna 20 is screwed.

図2は、第1の実施の形態における別の無線装置のアンテナ接続部の構成を示す側面図である。   FIG. 2 is a side view illustrating a configuration of an antenna connection unit of another wireless device according to the first embodiment.

図2に示す無線装置は、図1に示したものに対して、ミリ波モジュール11と円形−方形導波管変換部12をアンテナ20側に引っ張るバネ14を備える点で異なっている。ミリ波モジュール11と円形−方形導波管変換部12は、筐体10に固定されずアンテナ20方向に可動である。バネ14などの弾性体によりミリ波モジュール11と円形−方形導波管変換部12をアンテナ20側に引っ張ることにより、円形−方形導波管変換部12の円形開口部と接続部24の円形導波管242の接合面を押圧接合し、ぴったり合わせることができる。   The wireless device shown in FIG. 2 differs from that shown in FIG. 1 in that it includes a spring 14 that pulls the millimeter wave module 11 and the circular-rectangular waveguide converter 12 toward the antenna 20. The millimeter wave module 11 and the circular-rectangular waveguide converter 12 are not fixed to the housing 10 and are movable in the direction of the antenna 20. By pulling the millimeter wave module 11 and the circular-rectangular waveguide converter 12 toward the antenna 20 by an elastic body such as a spring 14, the circular opening of the circular-rectangular waveguide converter 12 and the circular guide of the connecting portion 24 are connected. The joining surface of the wave tube 242 can be pressed and joined together.

なお、図上でミリ波モジュール11の左側からミリ波モジュール11と円形−方形導波管変換部12をアンテナ20側に押す構成にしてもよい。   In addition, you may make it the structure which pushes the millimeter wave module 11 and the circular-rectangular waveguide conversion part 12 to the antenna 20 side from the left side of the millimeter wave module 11 on the figure.

図3は、第1の実施の形態におけるさらに別の無線装置のアンテナ接続部の構成を示す側面図である。   FIG. 3 is a side view illustrating a configuration of an antenna connection unit of still another wireless device according to the first embodiment.

図3に示すアンテナ20の本体は入出力が方形導波管である。一般に、ミリ波モジュール11の入出力は方形導波管であるので、アンテナの入出力も方形導波管であることが多い。そこで、同図に示す無線装置では、アンテナ20の本体と接続部24との間に円形−方形導波管変換部25を配置した。これにより、図1、図2で示した無線装置と同様に、筐体10とアンテナ20の導波管の接合面が円形となるので、筐体10にアンテナ20を精度良く取り付けることが可能となる。ただし、アンテナ20を筐体10取り付けたときに、アンテナ20の本体の方形導波管が所望の向きに配置されるように設計する必要がある。   The main body of the antenna 20 shown in FIG. 3 is a rectangular waveguide for input and output. In general, since the input / output of the millimeter wave module 11 is a rectangular waveguide, the input / output of the antenna is often a rectangular waveguide. Therefore, in the radio apparatus shown in FIG. 2, the circular-rectangular waveguide conversion unit 25 is disposed between the main body of the antenna 20 and the connection unit 24. As a result, as in the wireless device shown in FIGS. 1 and 2, the joint surface of the housing 10 and the waveguide of the antenna 20 becomes circular, so that the antenna 20 can be accurately attached to the housing 10. Become. However, it is necessary to design so that the rectangular waveguide of the main body of the antenna 20 is arranged in a desired direction when the antenna 20 is attached to the housing 10.

以上説明したように、本実施の形態によれば、アンテナ20が円柱形の接続部24を備え、筐体10が、接続部24の形状に合わせた円柱形の凹部を有する支持部13を備えるとともに、円柱形の接続部24の中心軸に沿って円形導波管242を形成し、円柱形の凹部の底面の中心において筐体10内部に配置し、ミリ波モジュール11に接続した円形−方形導波管変換部12の円形開口部を露出させることにより、接続部24を支持部13の凹部にはめ込むだけで簡易にアンテナ20を筐体10に取り付けることができる。また、接続部24、支持部13をねじ切り加工して雄ねじ部241、雌ねじ部131を形成することで、筐体10にアンテナ20をしっかりと固定されることができる。   As described above, according to the present embodiment, the antenna 20 includes the columnar connection portion 24, and the housing 10 includes the support portion 13 having the columnar recess that matches the shape of the connection portion 24. At the same time, a circular waveguide 242 is formed along the central axis of the cylindrical connecting portion 24, arranged inside the housing 10 at the center of the bottom surface of the cylindrical concave portion, and connected to the millimeter wave module 11. By exposing the circular opening of the waveguide conversion unit 12, the antenna 20 can be easily attached to the housing 10 simply by fitting the connection unit 24 into the recess of the support unit 13. Further, the antenna 20 can be firmly fixed to the housing 10 by forming the male screw part 241 and the female screw part 131 by threading the connection part 24 and the support part 13.

なお、図2に示したようにミリ波モジュール11と円形−方形導波管変換部12を筐体10に固定せず可動とし、円形−方形導波管変換部12の円形開口部と接続部の円形導波管242を押圧接合するバネ14を備えることで、円形−方形導波管変換部12の円形開口部と接続部24の円形導波管242の接合面をぴったり合わせてもよい。   As shown in FIG. 2, the millimeter wave module 11 and the circular-rectangular waveguide converter 12 are movable without being fixed to the casing 10, and the circular opening and the connecting part of the circular-rectangular waveguide converter 12 are connected. The circular opening 242 of the circular-rectangular waveguide converter 12 and the joint surface of the circular waveguide 242 of the connecting portion 24 may be closely aligned by providing the spring 14 that press-bonds the circular waveguide 242 of the above.
