Description

Active antenna

[technical field]

The utility model relates to communication technical field, relates in particular to a kind of active antenna.

[background technology]

At communication technical field, antenna is being served as the role of communication system terminal always.Industry adopts active antenna to realize the signal transmitting and receiving purpose usually.Active antenna refers to that the radio frequency part with the base station is integrated into a kind of antenna of Anneta module, and this active antenna adopts multichannel radio frequency and antenna a period of time to work in coordination to finish the transmitting-receiving of radiofrequency signal.

Existing active antenna is divided into two large classes basically: in the first active antenna, amplification module is integrated in the inside of Anneta module.In the second active antenna, with Remote Radio Unit and becoming one of Anneta module antenna.

The first active antenna is integrated in Anneta module inside with amplification module, its advantage is to reduce the installing space of Remote Radio Unit, its shortcoming is when amplification module goes wrong, repair cumbersome, and can only realize therefore having relatively high dilatation cost by the method that increases antenna amount during this active antenna dilatation.

Although the second active antenna is easy to maintenance, but because being electrically connected by RF cable between Remote Radio Unit and the Anneta module realizes, therefore cable waste is naturally inevitable, and then has affected the quality of communication link, and the dilatation cost of this active antenna is also higher.

Therefore, be necessary to provide a kind of improved active antenna, in order to overcome the shortcoming of prior art.

[utility model content]

The purpose of this utility model is to provide a kind of active antenna, and its grafting is convenient, the dilatation cost is low and communication link quality good.

For realizing this purpose, the utility model adopts following technical scheme:

A kind of active antenna, comprise Anneta module and be installed on the described Anneta module and with at least one active amplification module of its electric connection.Described Anneta module has the first Plug Division that the RF blind insertion socket is set on it; Described active amplification module has corresponding with described the first Plug Division and is provided with second Plug Division of inserting the RF blind insertion plug in the described RF blind insertion socket on it.

Compared with prior art, the utility model possesses following advantage:

In the utility model, the RF blind insertion plug effectively reduces with the grafting of RF blind insertion socket even has avoided Anneta module to be connected caused cable waste with active amplification module by cable, and then guarantees the communication link quality of active antenna; In addition, owing on the described Anneta module a plurality of active amplification modules can be set, therefore realized the dilatation of active antenna.

[description of drawings]

Figure 1A has showed the three-dimensional structure diagram of the active antenna of an embodiment of the utility model;

Figure 1B has showed the partial enlarged drawing at the active antenna A position shown in Figure 1A; And

Fig. 2 has showed the active antenna after the dilatation.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further described:

With reference to figure 1A-1B, according to an embodiment of the present utility model, a kind of active antenna 100 comprise Anneta module 1 and be installed on the described Anneta module 1 and with at least one active amplification module 2 of its electric connection.

Described Anneta module 1 has the first Plug Division 12, on the described Plug Division 12 RF blind insertion socket 122 is set; Described active amplification module 2 has second Plug Division 21 corresponding with described the first Plug Division 12, and on described the second Plug Division 21 RF blind insertion plug 22 is set; Described RF blind insertion plug 22 inserts in the described RF blind insertion socket 122, thereby realized being electrically connected between Anneta module 1 and the active amplification module 2.

In addition, offer location hole 124 on the first Plug Division 12 of described Anneta module 1; Form reference column 24 on the second Plug Division 21 of described active amplification module 2; Described reference column 24 accurate insertions in the described location hole 124.

Facilitate RF blind insertion plug 22 to insert like clockwork in the corresponding RF blind insertion socket 122 by above-mentioned reference column 24 and the precision-fit of location hole 124, thereby realized quickly and easily being electrically connected of Anneta module 1 and active amplification module 2.

Since adopted blindmate structure (fit structure of RF blind insertion plug 22 and RF blind insertion socket 122), therefore can be fast with Anneta module 1 and active amplification module 2 electrical interconnects; Simultaneously, above-mentioned blindmate structure decrease even avoided cable to connect caused cable waste, and then guarantee communication link quality.

Should be noted that: also can offer reference column (not label) on described the first Plug Division 12; Then form the location hole (not label) that inserts for described reference column on described the second Plug Division 21, thereby also can realize locating purpose.

In addition, with reference to figure 2, a plurality of active amplification modules 2 of can pegging graft on the described Anneta module 1 are in order to realize the dilatation of active antenna 100.

Preferably, described active amplification module 2 further comprises the sealing strip 26 that is sealed in the plugging position place after described RF blind insertion socket 122 is pegged graft mutually with described RF blind insertion plug 22, is used for realizing waterproof action.

Preferably, described active amplification module 2 is installed on the described Anneta module 1 by connector 28.Particularly, described connector 28 comprises the first connecting portion 282 and the second connecting portion 284 that is bent to form with a end from the first connecting portion 282.Pass the first connecting portion 282 and screw in described the second Plug Division 21 by the first screw 286 and realize connector 28 is fixed on the active amplification module 2; Realize connector 28 is fixed on the Anneta module 1 by the second screw 288 being passed the second connecting portion 284 and screwing in described the first Plug Division 12, and then active amplification module 2 is installed on described Anneta module 1.
