The mobile communication transmission grounding device provided by the utility model enables the transmission wire to be grounded directly, thereby not only achieving reliable grounding, but also enabling the base station equipment and the transmission equipment to achieve the unification of grounding, reducing the error code rate of the mobile communication signals, and ensuring the transmission quality of the mobile communication signals.
Description
Technical field
The utility model relates to a kind of earthing device, relates in particular to a kind of mobile communication transmission earthing device.
Background technology
At present, transmission equipment is sent to mobile communication signal in the process of base station equipment by transmission line in the mobile communication base station, error rate condition with higher can appear, the appearance of this situation is generally caused by hardware problem, as associated transport device interface board fault, the transmission line junction welding is bad, the problem with grounding of DDF (Digital DistributionFrame, digital distribution frame) etc.
Wherein comparatively common reason is: base station equipment is provided with the particular port of grounding function, and transmission equipment is directly connected to particular port on the described base station equipment by transmission line, thereby makes transmission line in transmit communications signals, by base station equipment ground connection.At first, the technological requirement of this kind earthing method butt joint is very high, and along with the increase of service time, the ground connection effect can decrease, simultaneously the signal of communication transmission quality is gone wrong, cause base station performance to descend, can't open, even occur in situation with base station service quit.Secondly, the method can cause the ground connection disunity of base station equipment and transmission equipment, and both acquire a certain degree at voltage difference, will cause the metal screen layer in the transmission line to have small amount of current to flow through, thereby the signal of communication transmission quality of influence transmission core causes a large amount of error codes.
Now need to provide a kind of new device in order to improve or to address the above problem.
The utility model content
The technical problems to be solved in the utility model is: a kind of mobile communication transmission earthing device is provided, avoided because the ground connection effect instability that transmission line causes by base station equipment ground connection, and the ground connection disunity of transmission equipment and base station equipment and high bit-error that the signal of communication that causes transmits.
The utility model solves above-mentioned technical problem by such technical scheme:
A kind of mobile communication transmission earthing device, be installed in inside of base station, also comprise transmission equipment, base station equipment and dead earth device in the base station, transmission equipment links to each other with base station equipment by transmission line, described mobile communication transmission earthing device one end links to each other with the transmission line of close transmission equipment, and the other end is connected to base station internal fixation earthing device.
Further, described mobile communication transmission earthing device comprises earth connection, and this earth connection one end is connected with the transmission line of close transmission equipment.
Wherein, described transmission line comprises metal screen layer, and the end connector that earth connection connects transmission line is the anchor ear shape, is used to bind round the metal screen layer in the firm transmission line.
Further, the transmission earthing device of described mobile communication base station also comprises ground plate, and this ground plate one end is connected with earth connection, and the other end is installed on the dead earth device.
Wherein, have draw-in groove on the described ground plate, earth connection is plugged in the draw-in groove.
Wherein, described dead earth device is the ground connection bronze medal.
Compared with prior art, advantage of the present utility model is:
1, the metal screen layer of transmission line directly links to each other with base station internal fixation earthing device, makes transmission line in transmit communications signals, reaches the effect of reliable ground;
2, it is unified to make base station equipment and transmission equipment reach ground connection, avoided because transmission equipment and base station equipment ground connection disunity, and cause the voltage difference that in the signal of communication transmission course, produces, thereby eliminated the small amount of current on the transmission line metal screen layer, and consequent transmission line core transmit communications signals performance decrease, avoid the high bit-error of signal of communication transmission, improved the communication signal transmission quality.
Description of drawings

Fig. 2 is the schematic diagram of earth connection in the utility model mobile communication transmission earthing device.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model provides a kind of mobile communication transmission earthing device 1, this device 1 is installed in the inside of mobile communication base station 10, this base station 10 comprises transmission equipment 2, base station equipment 3 and dead earth device 5 at least, transmission equipment 2 links to each other with base station equipment 3 by transmission line, transmits mobile communication signal.
Mobile communication transmission earthing device 1 comprises earth connection 11 and ground plate 12.Earth connection 11 links to each other with the transmission line of close transmission equipment 2 one sides; Ground plate 12 1 ends connect earth connection 11, and the other end is installed on the dead earth equipment 5 by brass screws.
The end connector 111 that earth connection 11 connects transmission line is the anchor ear shape, when earth connection 11 links to each other with the transmission line of close transmission equipment 2 one sides, need earlier with the epidermal area strip off of transmission line near transmission equipment 2 one ends, the metal screen layer that exposes transmission line is set in an end of earth connection 11 band anchor ear straight couplings 111 on the metal screen layer of transmission line again and tightens up.
Also be provided with draw-in groove on the ground plate 12, the end that earth connection 11 is connected to ground plate 12 is plugged in the draw-in groove of ground plate 12.Transmission line can pass through earth connection 11 and ground plate 12, can be connected to dead earth device 5, realizes the direct ground connection of transmission line.
In the utility model preferred embodiment, described dead earth device 5 is for being arranged on the ground connection bronze medal of 10 inside, base station.
The above-mentioned improvement that the utility model has been done, make the direct ground connection of transmission line, not only reached the effect of reliable ground, and it is unified to make base station equipment 3 and transmission equipment 2 reach ground connection, reduce the error rate of mobile communication signal, guaranteed the transmission quality of mobile communication signal.
The above only is a better embodiment of the present utility model; protection range of the present utility model does not exceed with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
