Abstract
The utility model discloses a 4G double-inlet double-outlet bridge for telecommunication, which comprises a housing. A cavity is opened in the housing, multiple installation holes are arranged in the sides of the cavity, a coupling rod is mounted in the cavity, a sleeve is sleeved on the middle portion of the coupling rod, multiple support media are arranged on the coupling rod, an adjusting medium is mounted outside the sleeve, two input ends are installed at one side of the housing, two output ends are installed at the other side of the housing, the input and output ends are connected to the coupling rod via copper wires, and the top of the housing includes a cover plate. The 4G double-inlet double-outlet bridge is mainly applied to multiple signal combination in China Telecom, the utilization rate of output signals is improved, base-station signals are widely combined via an indoor coverage system, the coupling rod of the bridge can adjust standing waves and in-band insert loss, all the indexes can be directly controlled via size precision and installation positions of the internal support media and adjusting medium, and the sleeve can control the distance between conducting rods to prevent that the total index is influenced due to that the parallelism or height between the conducting rods is not well controlled during assembly; and the 4G double-inlet double-outlet bridge also has the advantages including small volume, convenient installation and maintenance and low cost.
Description
Technical field:
The utility model relates to the mobile communication equipment field, relates in particular to a kind of telecommunications and advances the scene 2 electric bridge with 4G two.
Background technology:
Wireless communication technology is through for many years development, enters the 3G epoch from the GSM epoch, and following more advanced 4G network had can be practical technology, pilot is also arranged at home, and domestic application is also rare in the equipment of 4G network.
Therefore imagination provides a kind of telecommunications to advance the scene 2 electric bridge with 4G two, be mainly used in the many signals of China Telecom and close the road, improve the utilance of output signal, in the extensive use indoor covering system to the road of closing of base station signal, it is four port network that this telecommunications is advanced the scene 2 electric bridge with 4G two, and its characteristic is two-port input, two-port output, and two input ports are isolated mutually, two output ports are respectively exported 50% of input power, and phase of output signal differs 90 degree.Be connected with other electronic circuits in system for convenient, structurally port 2 and 3 need to be in same direction, so can be with parallel coupling line segment mutual dislocation.The length of parallel coupled line should design at 1/4 channel combine, and the degree mutual close according to flat coupling line can obtain different coupling level output at port 2.Be the situation of 1:1 for coupled power ratio, straightthrough port and the output of coupling aperture constant amplitude balance, phase phasic difference 90 degree are exactly that Novel electric credit 4G two advances the scene 2 electric bridge.
The utility model content:
The purpose of this utility model just is to provide a kind of telecommunications and advances the scene 2 electric bridge with 4G two, is mainly used in the many signals of China Telecom and closes the road, improves the utilance of output signal, in the extensive use indoor covering system to the road of closing of base station signal.
The technical solution adopted in the utility model is:
A kind of telecommunications is advanced the scene 2 electric bridge with 4G two, comprise housing: have cavity in housing, the cavity limit is provided with some installing holes, and coupling bar is installed in cavity, and sleeve is installed in the middle part of coupling bar, be provided with some Supporting Medias on coupling bar, sleeve is equipped with the adjustment medium outward, and housing one side is equipped with two inputs, and opposite side is equipped with two outputs, input and output all are connected to coupling bar by copper cash, and case top has cover plate.
Described Supporting Media is the conduction barred body.
Described input and output all adopt the base station with 7/16 type high turbine spare, inner copper material, plated surface ternary alloy three-partalloy.
Be provided with some location and installation holes on described cover plate, match with installing hole on box body.
Be welded to connect between described copper cash and coupling bar.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is mainly used in the many signals of China Telecom and closes the road, improve the utilance of output signal, in the extensive use indoor covering system to the road of closing of base station signal, its coupling bar can be regulated Insertion Loss in standing wave and band, all indexs can directly be controlled in dimensional accuracy and the installation site of inner Supporting Media and adjustment medium, distance between the controlled contact rod processed of sleeve is in case the depth of parallelism between when assembling bad control contact rod or height and cause affecting overall objective; Integral body has the plurality of advantages such as volume is light, convenient for installation and maintenance, cost is low.
