Abstract
The utility model relates to a radio remote unit suitable for indoor and outdoor application, comprising a radio remote module. The radio remote module comprises an upper cavity, a lower cavity and a front panel; a waterproof rubber ring is arranged at the involutory position of the upper cavity and the lower cavity; and interfaces are arranged on the front panel. In the radio remote unit, the radio remote module adopts a semitight structure, other assemblies are waterproof and airproof except the front panel, and all the interfaces are arranged on the front panel. All adopted interface devices are indoor devices which have lower price and smaller volume compared with outdoor devices so as to be suitable for the application of more module interfaces. In addition, the radio remote unit is provided with a semitight outdoor machine cabinet which can be simultaneously applied to indoor and outdoor base stations so as to achieve the general purpose of the indoor and outdoor modules; and due to the double seal of the machine cabinet and the radio remote module, the sealing performance is also very good.
Description
Technical field
The utility model relates to the Remote Radio Unit of a kind of GSM base station, particularly a kind of Remote Radio Unit that is applicable to indoor and outdoors simultaneously.
Background technology
For the Remote Radio Unit of GSM (Global System for Mobile communication, global system for mobile communications), has the application requirements of indoor and outdoors simultaneously.If design a kind of indoor type unit, can be applied to outdoorly simultaneously, for logistics management, cost control etc. very big benefit is arranged.
In the outdoor utility occasion, need Remote Radio Unit to reach the waterproof sealing requirement.And for the bigger GSM base station of capacity, the Remote Radio Unit intermodule needs more radio frequency interface communication, if module interface adopts the waterproof sealing device, on the one hand because the volume of hermetically sealed connector is relatively large, for the module that strict volume requirement is arranged, go out very difficulty of more closed type interface from a face; On the other hand, the closed type device cost is higher, and intermodule has more interface interconnected, and the security risk of system also increases greatly.
The utility model content
The technical problems to be solved in the utility model provides a kind of Remote Radio Unit, has good sealing property and flexibility, has both gone for indoor environment, also go for outdoor environment, and cost is low.
In order to address the above problem, the utility model provides a kind of Remote Radio Unit that indoor and outdoors is used that satisfies, comprise radio frequency remoto module, described radio frequency remoto module comprises upper cavity, lower chamber and front panel, is provided with waterproof apron between described upper cavity and lower chamber apposition position; Described front panel is provided with interface.
Further, the apposition position with described upper cavity on the described lower chamber is provided with a circle groove, and described waterproof apron is arranged in this groove.
Further, link to each other by hinge between described upper cavity and the lower chamber.
Further, also be connected and fixed between described upper cavity and the lower chamber by screw.
Further, also comprise rack, described rack bag cabinet and Qianmen are provided with waterproof apron between the contact position at described cabinet and Qianmen; Be provided with the guide rail that is used to install described radio frequency remoto module in the described cabinet.
Further, the edge of the front panel of described radio frequency remoto module exceeds the edge of described upper cavity and lower chamber, the back side that described front panel exceeds described upper cavity and lower chamber part is provided with waterproof apron, be installed on the guide rail of described cabinet at described radio frequency remoto module after, realize the sealing between described radio frequency remoto module and guide rail.
Further, described rack is provided with the waterproof wire clamp, and feeder line, the power line that passes in and out rack sealed.
Remote Radio Unit of the present utility model, its radio frequency remoto module adopts semitight structure, and except that front panel, other each faces are all accomplished waterproof sealing, and all interfaces are plate in front all.The interface device that is adopted is the indoor type device, because the indoor type device is lower with respect to outdoor version device price, and volume is less relatively, more can satisfy the application with more module interface.In addition, Remote Radio Unit of the present utility model has been equipped with the Cabinet of semitight, can be applied to the indoor and outdoors base station simultaneously, realizes the general of indoor and outdoors module, because the dual-seal of rack and radio frequency remoto module, its sealing property is also fine.
