Description

A remote radio unit for indoor and outdoor applications

technical field

The utility model relates to a radio remote unit of a GSM base station, in particular to a radio remote unit suitable for both indoors and outdoors.

Background technique

For the remote radio unit of GSM (Global System for Mobile communication, Global System for Mobile Communication), it has both indoor and outdoor application requirements. If an indoor unit is designed, it can be used outdoors at the same time, which will have great benefits for logistics management and cost control.

In outdoor applications, the remote radio unit needs to meet the waterproof and sealing requirements. For GSM base stations with larger capacity, more RF interface communication is required between the remote radio unit modules. If the module interface adopts waterproof sealing devices, on the one hand, due to the relatively large volume of the sealed connector, for those with strict volume requirements As far as modules are concerned, it is very difficult to have more sealed interfaces on one surface; on the other hand, the cost of sealed devices is relatively high, and there are many interfaces interconnected between modules, which greatly increases the reliability risk of the system.

Utility model content

The technical problem to be solved by the utility model is to provide a remote radio unit with good airtightness and flexibility, suitable for both indoor and outdoor environments, and low in cost.

In order to solve the above problems, the utility model provides a remote radio unit for indoor and outdoor applications, including a remote radio module, and the remote radio module includes an upper cavity, a lower cavity and a front panel. A waterproof rubber ring is provided between the junction of the upper cavity and the lower cavity; an interface is provided on the front panel.

Further, a groove is provided at the junction of the lower cavity and the upper cavity, and the waterproof rubber ring is set in the groove.

Further, the upper cavity and the lower cavity are connected by a hinge.

Further, the upper cavity and the lower cavity are fixed by screw connection.

Further, it also includes a cabinet, the cabinet includes a cabinet body and a front door, and a waterproof rubber ring is provided between the contact between the cabinet body and the front door; guide rails for installing the remote radio module are provided in the cabinet.

Further, the edge of the front panel of the radio remote module exceeds the edge of the upper cavity and the lower cavity, and the back of the front panel beyond the upper cavity and the lower cavity is provided with a waterproof rubber ring, After the remote radio module is installed on the guide rail of the cabinet, the sealing between the remote radio module and the guide rail is realized.

Further, the cabinet is provided with a waterproof wire clamp to seal the feeder and power wires entering and leaving the cabinet.

In the radio remote unit of the present invention, the radio remote module adopts a semi-sealed structure, except for the front panel, all other surfaces are waterproof and sealed, and all interfaces are on the front panel. The interface devices used are all indoor devices. Compared with outdoor devices, the price of indoor devices is lower, and the volume is relatively smaller, which can better meet the application with more module interfaces. In addition, the radio remote unit of the utility model is equipped with a semi-sealed outdoor cabinet, which can be applied to indoor and outdoor base stations at the same time to realize the common use of indoor and outdoor modules. Due to the double sealing of the cabinet and the remote radio module, its sealing performance is also very good.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the utility model and implement it, but the examples given are not intended to limit the utility model.

The radio remote unit of the utility model includes a radio remote module and a cabinet. As shown in FIG. 1 , the remote radio module includes an upper chamber 1 , a lower chamber 2 and a front panel 3 , and an interface 4 is provided on the front panel 3 . As shown in Figure 2, the upper and lower chambers 1 and 2 are connected by a hinge 5 on one edge, and a groove is provided at the joint of the lower chamber 2 and the upper chamber 1, and a waterproof rubber ring is provided in the groove 8. A plurality of screw holes 6 are oppositely arranged on the upper and lower cavities 1 and 2 where the upper and lower cavities 1 and 2 meet each other. When the upper and lower cavities 1 and 2 are combined, screws 7 can be used to penetrate Through these screw holes 6, the upper and lower chambers 1, 2 are fastened together. The radio remote module of the utility model is a semi-sealed module, except for the front panel 3 , all other surfaces are sealed, and all interfaces are drawn out from the front panel 3 .

As shown in Figure 3, in order to adapt to the outdoor application environment, the radio remote unit of the present invention is also equipped with a cabinet, the cabinet is composed of a cabinet body 9 and a front door (not shown in the figure), the junction of the cabinet body 9 and the front door Be provided with waterproof rubber ring 8.
