　補強部５３ｂは、ステンレス等の金属材料からなる。補強部５３ｂは、蓋体５３が容器本体５２の開口部５１を閉鎖した状態で、開口部５１を全面にわたって覆うように延伸して配設され、かつ、無線基地局装置１０にて送受信される電波Ｅが透過可能な少なくとも１つの電波透過開口５３ｂ１が形成されている。本実施形態の補強部５３ｂは、図２及び図３に示すように、複数の網目を有する網状体で構成されている。電波透過開口５３ｂ１は、複数の網目のうちの少なくとも１つの網目である。また、補強部５３ｂは、樹脂部５３ａの厚さ方向の中央部に埋め込まれている。電波透過開口５３ｂ１は、図３に示すように、略矩形状に形成され、少なくとも短い辺の寸法Ｗが、無線基地局装置１０にて送受信される電波Ｅの波長の半分以上の寸法である。 The reinforcing portion 53b is made of a metal material such as stainless steel. The reinforcing portion 53b is arranged so as to extend so as to cover the entire surface of the opening 51 in a state where the lid 53 closes the opening 51 of the container body 52, and is transmitted and received by the radio base station apparatus 10. At least one radio wave transmission opening 53b1 through which the radio wave E can pass is formed. As shown in FIGS. 2 and 3, the reinforcing portion 53b of the present embodiment is composed of a mesh-like body having a plurality of meshes. The radio wave transmission opening 53b1 is at least one of the plurality of meshes. Further, the reinforcing portion 53b is embedded in the central portion of the resin portion 53a in the thickness direction. As shown in FIG. 3, the radio wave transmission opening 53b1 is formed in a substantially rectangular shape, and the dimension W of at least the short side is a dimension of half or more of the wavelength of the radio wave E transmitted and received by the radio base station apparatus 10.

Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　表１において、例えば、電波Ｅの周波数が４．８ＧＨｚの場合に、波長が６２．５ｍｍとなるため、電波透過開口５３ｂ１の少なくとも短い辺の寸法Ｗは、３１．３ｍｍ以上に設定される。 In Table 1, for example, when the frequency of the radio wave E is 4.8 GHz, the wavelength is 62.5 mm, so that the dimension W of at least the short side of the radio wave transmission opening 53b1 is set to 31.3 mm or more.
　以上のように構成された樹脂容器５において、無線基地局装置１０を収容空間５ａに設置する際には、ブラケット５２ｃを介してアンテナ部１２を容器本体５２の側面部５２ｂに取り付ける。このとき、容器本体５２の収容空間５ａにおけるアンテナ部１２の取り付け位置は、アンテナ部１２の放射素子１２ｂが、容器本体５２に固定された蓋体５３の補強部５３ｂの電波透過開口５３ｂ１の直下に位置するように調整される。 In the resin container 5 configured as described above, when the radio base station device 10 is installed in the accommodation space 5a, the antenna portion 12 is attached to the side surface portion 52b of the container body 52 via the bracket 52c. At this time, the mounting position of the antenna portion 12 in the accommodation space 5a of the container main body 52 is such that the radiating element 12b of the antenna portion 12 is directly below the radio wave transmission opening 53b1 of the reinforcing portion 53b of the lid 53 fixed to the container main body 52. Adjusted to be positioned.
　このとき、補強部５３ｂは、蓋体５３が容器本体５２の開口部５１を閉鎖した状態で、開口部５１を全面にわたって覆うことになる。このため、蓋体５３は、破壊に対する強度が向上するとともに、例えばディスクグラインダ等の工具によって補強部５３ｂを切断する際に大きな音が発生することになる。このため、樹脂容器５は、蓋体５３の破壊による容器本体５２の開口部５１の開放を抑制することが可能となり、蓋体５３を破壊して容器本体５２に収容された無線基地局装置１０の盗難や破壊等の被害を抑制することが可能となる。 At this time, the reinforcing portion 53b covers the entire surface of the opening 51 with the lid 53 closing the opening 51 of the container body 52.

It is possible to suppress deterioration of communication performance of wireless communication between the base station device 10 and the wireless communication device.
　このように、本実施形態の樹脂容器５によれば、上面に開口部５１を有し、内部にケーブル（通信線６及び電力線７）及び無線基地局装置を収容する容器本体５２と、開口部５１を閉鎖する蓋体５３と、蓋体５３を補強する補強部５３ｂと、を備え、補強部５３ｂは、蓋体５３が開口部５１を閉鎖した状態で、開口部５１を全面にわたって覆うように延伸して配設され、かつ、無線基地局装置１０において送受信される電波Ｅを透過可能な少なくとも１つの電波透過開口５３ｂ１を有している。 As described above, according to the resin container 5 of the present embodiment, the container body 52 having an opening 51 on the upper surface and accommodating the cable (communication line 6 and power line 7) and the radio base station device inside, and the opening.

It has at least one radio wave transmission opening 53b1 that is elongated and is capable of transmitting radio waves E transmitted and received by the radio base station apparatus 10.
　これにより、アンテナ部１２において送受信される電波Ｅが蓋体５３を透過可能な状態で、蓋体５３の強度を向上させることができるので、無線基地局装置１０と無線通信機器との無線通信の通信性能を低下させることなく、容器本体５２の内部に収容された無線基地局装置１０を構成する機器の盗難や破損等の被害を抑制することが可能となる。 As a result, the strength of the lid 53 can be improved in a state where the radio waves E transmitted and received in the antenna portion 12 can pass through the lid 53, so that the radio communication between the radio base station device 10 and the wireless communication device can be performed. It is possible to suppress damage such as theft or damage of the equipment constituting the wireless base station device 10 housed inside the container main body 52 without deteriorating the communication performance.
　また、補強部５３ｂは、複数の網目を有する網状体で構成され、電波透過開口５３ｂ１は、複数の網目の少なくとも１つの網目である、ことが好ましい。 Further, it is preferable that the reinforcing portion 53b is composed of a mesh body having a plurality of meshes, and the radio wave transmission opening 53b1 is at least one mesh of the plurality of meshes.
　これにより、蓋体５３に複数の電波透過開口５３ｂ１が配置されることになるので、アンテナ部１２において送受信される電波Ｅをより確実に透過させることが可能となり、無線基地局装置１０と無線通信機器との通信性能の低下を効果的に抑制することが可能となる。 As a result, since a plurality of radio wave transmission openings 53b1 are arranged in the lid 53, it is possible to more reliably transmit the radio wave E transmitted and received by the antenna unit 12, and wireless communication with the radio base station device 10. It is possible to effectively suppress the deterioration of communication performance with the device.
　また、補強部５３ｂは、蓋体５３の内部に埋め込まれている、ことが好ましい。 Further, it is preferable that the reinforcing portion 53b is embedded inside the lid 53.

　本実施形態の樹脂容器５は、容器本体５２の内部に無線基地局装置１０の本体部１１が収容され、蓋体５３にアンテナ部１２が収容されている。アンテナ部１２は、蓋体５３の樹脂部５３ａの内部に埋め込まれている。 In the resin container 5 of the present embodiment, the main body 11 of the radio base station device 10 is housed inside the container body 52, and the antenna part 12 is housed in the lid 53. The antenna portion 12 is embedded inside the resin portion 53a of the lid 53.
　蓋体５３は、アンテナ部１２の下方位置に設けられ、蓋体５３を補強する補強部５３ｅを有している。補強部５３ｅは、蓋体５３が開口部５１を閉鎖した状態で、開口部５１を全面にわたって覆うように延伸して配設されている。ここで、補強部５３ｅは、アンテナ部１２の下方に位置しているため、第１乃至第４実施形態のような、電波透過開口を有していなくてもよい。 The lid 53 is provided at a position below the antenna portion 12 and has a reinforcing portion 53e that reinforces the lid 53. The reinforcing portion 53e is arranged so as to extend so as to cover the entire opening portion 51 in a state where the lid 53 closes the opening portion 51. Here, since the reinforcing portion 53e is located below the antenna portion 12, it does not have to have the radio wave transmission opening as in the first to fourth embodiments.
　以上のように構成された樹脂容器５において、補強部５３ｅは、蓋体５３が容器本体５２の開口部５１を閉鎖した状態で、開口部５１を全面にわたって覆うことになる。このため、蓋体５３は、破壊に対する強度が向上する。また、アンテナ部１２において送受信される電波Ｅは、蓋体５３の樹脂部５３ａを透過する。本実施形態では、アンテナ部１２が、蓋体５３の樹脂部５３ａに埋め込まれた状態となっており、アンテナ部１２の放射素子１２ｂを覆う樹脂材料の厚さ方向寸法が小さくなるため、無線基地局装置１０と無線通信機器との無線通信の通信性能が向上する。 In the resin container 5 configured as described above, the reinforcing portion 53e covers the entire opening portion 51 with the lid 53 closing the opening 51 of the container main body 52. Therefore, the lid 53 has improved strength against breakage. Further, the radio wave E transmitted and received by the antenna portion 12 passes through the resin portion 53a of the lid 53. In the present embodiment, the antenna portion 12 is embedded in the resin portion 53a of the lid 53, and the thickness direction dimension of the resin material covering the radiating element 12b of the antenna portion 12 becomes small. The communication performance of wireless communication between the station device 10 and the wireless communication device is improved.
　このように、本実施形態の樹脂容器５によれば、上面に開口部５１を有し、内部にケーブル（通信線６及び電力線７）及び無線基地局装置１０の本体部１１を収容する容器本体５２と、内部に無線基地局装置１０のアンテナ部１２が埋め込まれ、開口部５１を閉鎖する蓋体５３と、アンテナ部１２の下方位置に設けられ、蓋体５３を補強する補強部５３ｅと、を備え、補強部５３ｅは、蓋体５３が開口部５１を閉鎖した状態で、開口部５１を全面にわたって覆うように延伸して配設される。 As described above, according to the resin container 5 of the present embodiment, the container body has an opening 51 on the upper surface and houses the cable (communication line 6 and power line 7) and the main body 11 of the radio base station device 10 inside. 52, a lid 53 in which the antenna portion 12 of the radio base station device 10 is embedded to close the opening 51, and a reinforcing portion 53e provided below the antenna portion 12 to reinforce the lid 53. The reinforcing portion 53e is arranged so as to extend so as to cover the entire surface of the opening 51 with the lid 53 closing the opening 51.
　これにより、アンテナ部１２において送受信される電波Ｅが蓋体５３を透過可能な状態で、蓋体５３の強度を向上させることができるので、無線基地局装置１０と無線通信機器との無線通信の通信性能を低下させることなく、容器本体５２の内部に収容された無線基地局装置１０を構成する機器の盗難や破損等の被害を抑制することが可能となる。 As a result, the strength of the lid 53 can be improved in a state where the radio waves E transmitted and received in the antenna portion 12 can pass through the lid 53, so that the radio communication between the radio base station device 10 and the wireless communication device can be performed. It is possible to suppress damage such as theft or damage of the equipment constituting the wireless base station device 10 housed inside the container main body 52 without deteriorating the communication performance.
　尚、第１乃至第４実施形態では、補強部５３ｂ，５３ｃ，５３ｄの電波透過開口５３ｂ１，５３ｃ１，５３ｄ１を、矩形状に形成したものを示したが、アンテナ部において送受信される電波が透過可能な開口であれば、矩形状に限られるものではない。 In the first to fourth embodiments, the radio wave transmission openings 53b1, 53c1, 53d1 of the reinforcing portions 53b, 53c, 53d are shown in a rectangular shape, but the radio waves transmitted and received in the antenna portion can be transmitted. The opening is not limited to a rectangular shape.
