Description

本発明は、移動電話システムに於ける不感地対策として設置される無線中継増幅装置に関するものである。   The present invention relates to a wireless relay amplification device installed as a dead zone countermeasure in a mobile telephone system.

無線中継増幅装置は、移動電話システムに於ける電波の届きに不感地での小規模なエリアをカバーする為に設置されるものであり、図６に於いて構成の概略を説明する。   The wireless relay amplification device is installed to cover a small area in a dead zone where radio waves reach the mobile telephone system. The outline of the configuration will be described with reference to FIG.

無線中継増幅装置１は主に、基地向けアンテナ２、第１共用器３、増幅部４、第２共用器５、移動局向けアンテナ６から構成され、前記基地向けアンテナ２で上り下り回線信号を送受信し、前記第１共用器３では上り下り回線信号を分配合成し、前記増幅部４では分配合成された信号を増幅し、更に前記第２共用器５で分配合成し、前記移動局向けアンテナ６により上り下り回線信号を送受信する様になっている。   The radio relay amplifying apparatus 1 mainly includes a base antenna 2, a first duplexer 3, an amplification unit 4, a second duplexer 5, and a mobile station antenna 6. The base antenna 2 transmits an uplink / downlink signal. The first duplexer 3 distributes and synthesizes the uplink / downlink signal, the amplifying unit 4 amplifies the distributed and synthesized signal, and further distributes and synthesizes the signal in the second duplexer 5. 6 transmits and receives uplink / downlink signals.

前記第１共用器３、第２共用器５は急峻な特性を要求され大型になるので、前記増幅部４とは一体構造とせず別体とされ、ケーブルにより接続されていた。   Since the first duplexer 3 and the second duplexer 5 are required to have steep characteristics and become large in size, they are separated from the amplifying unit 4 without being integrated, and are connected by cables.

図７、図８は従来の無線中継増幅装置を示しており、増幅装置１１と共用装置１２とがケーブル１３によって接続されている。前記増幅装置１１はフィン１４を有する筐体１５の内部に増幅部４、基地向けアンテナ２、移動局向けアンテナ６が内蔵されている。又、前記共用装置１２には第１共用器３、第２共用器５が内蔵され、該第１共用器３、第２共用器５は前記ケーブル１３により前記増幅部４に接続されている。   7 and 8 show a conventional wireless relay amplifying device, in which an amplifying device 11 and a shared device 12 are connected by a cable 13. The amplifying device 11 includes an amplifying unit 4, a base antenna 2, and a mobile station antenna 6 inside a casing 15 having fins 14. The shared device 12 includes a first duplexer 3 and a second duplexer 5, and the first duplexer 3 and the second duplexer 5 are connected to the amplification unit 4 by the cable 13.

上記した従来の無線中継増幅装置では、前記増幅装置１１と前記共用装置１２が別体となっているので、取扱い作業性が悪い。又ケーブル１３が長くなることからケーブルロスが発生し、特性の劣化、ケーブル配線スペースが必要となる等の問題があった。   In the above-described conventional wireless relay amplification device, the amplification device 11 and the shared device 12 are separate, so that handling workability is poor. Further, since the cable 13 becomes long, there is a problem that a cable loss occurs, characteristics are deteriorated, and a cable wiring space is required.

特開平６−６１９０２号公報JP-A-6-61902

本発明は斯かる実情に鑑み、共用器と増幅部とを一体とし、小型化、軽量化を図ると共に電気的特性を向上させるものである。   In view of such circumstances, the present invention integrates a duplexer and an amplifying unit to reduce the size and weight and improve the electrical characteristics.

本発明は、筐体を少なくとも下部ケース、上部ケースの２分割構造とし、前記下部ケース、前記上部ケースのいずれか一方に増幅部が設けられ、いずれか他方に共用部が設けられ、前記下部ケース、前記上部ケースを一体化することで前記増幅部と前記共用部とが接続される様構成した無線中継増幅装置に係るものである。   In the present invention, the housing has a two-part structure of at least a lower case and an upper case, an amplification unit is provided in one of the lower case and the upper case, and a shared unit is provided in the other, and the lower case Further, the present invention relates to a radio relay amplifying apparatus configured such that the amplifying unit and the shared unit are connected by integrating the upper case.

以下、図面を参照しつつ本発明を実施する為の最良の形態を説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

図１〜図３に於いて、図７、図８中で示したものと同等のものには同符号を付してある。   1 to 3, the same components as those shown in FIGS. 7 and 8 are denoted by the same reference numerals.

筐体１７は、下部ケース１８、上部ケース１９の２分割構造であり、側面に突設されたフランジ部２１をボルト２２により固定することで前記下部ケース１８、上部ケース１９が一体化される。前記下部ケース１８、上部ケース１９の内、少なくとも前記下部ケース１８はアルミダイカスト製であり、外面にはフィン２３が形成されている。前記上部ケース１９の上面には凹部２４が形成され、該凹部２４には球面支持部２５を介してアンテナ、例えば移動局向けアンテナ６が任意の方向に傾動可能に設けられ、該移動局向けアンテナ６は後述する共用部３１に接続されている。又、前記凹部２４はアンテナカバー２６により覆われている。   The casing 17 has a two-part structure of a lower case 18 and an upper case 19, and the lower case 18 and the upper case 19 are integrated by fixing a flange portion 21 projecting from a side surface with a bolt 22. Of the lower case 18 and the upper case 19, at least the lower case 18 is made of aluminum die casting, and fins 23 are formed on the outer surface. A concave portion 24 is formed on the upper surface of the upper case 19, and an antenna, for example, a mobile station antenna 6 is provided in the concave portion 24 via a spherical support portion 25 so as to be tiltable in an arbitrary direction. 6 is connected to a shared section 31 to be described later. The recess 24 is covered with an antenna cover 26.

前記下部ケース１８の底部には増幅部４が固着され、該増幅部４から発せられる熱が前記フィン２３より放熱される様になっている。又、底部にはコネクタ支持部材２７が設けられ、該コネクタ支持部材２７には同軸コネクタ２８が取付けられ、該同軸コネクタ２８と前記増幅部４とはケーブル２９によって接続されている。   The amplifying unit 4 is fixed to the bottom of the lower case 18, and heat generated from the amplifying unit 4 is radiated from the fins 23. A connector support member 27 is provided at the bottom, and a coaxial connector 28 is attached to the connector support member 27, and the coaxial connector 28 and the amplifying unit 4 are connected by a cable 29.

前記上部ケース１９の天井部には共用部３１が取付けられ、該共用部３１は図６中で示した第１共用器３、第２共用器５を具備している。前記共用部３１は前記上部ケース１９内部の空間を略全体に亘って占有しており、充分大きい収納スペースに組込まれる。又、該上部ケース１９の天井部にはコネクタ支持部材３２が設けられ、該コネクタ支持部材３２には同軸コネクタ３３が取付けられ、該同軸コネクタ３３と前記共用部３１とはケーブル３４によって接続されている。前記上部ケース１９の１側面には基地向けアンテナ用接続端子３６が設けられており、該基地向けアンテナ用接続端子３６を介して基地向けアンテナ（図示せず）が前記共用部３１に接続される。   A shared portion 31 is attached to the ceiling portion of the upper case 19, and the shared portion 31 includes the first duplexer 3 and the second duplexer 5 shown in FIG. 6. The shared portion 31 occupies almost the entire space inside the upper case 19 and is incorporated in a sufficiently large storage space.

Since the common part 31 is integrated, installation work is easy. The inclination of the mobile station antenna 6 is adjusted in the installed state, and the delicate directivity of the mobile station antenna 6 is adjusted.

尚、該移動局向けアンテナ６は内蔵せず別途設けケーブルで接続する様にしてもよい。又、上部ケース１９に増幅部４を設け、下部ケース１８に共用部３１を設ける様にしてもよいことは言う迄もない。   The mobile station antenna 6 may be provided separately and connected via a cable. Needless to say, the upper case 19 may be provided with the amplifying unit 4 and the lower case 18 may be provided with the common unit 31.
