Technical field
The present invention relates to electric bridges, and in particular to a kind of low intermodulation Two In and One Out electric bridge.
Background technology
As the important component in telecommunication transmission system, the bridge joint between system and system is required for passing through electricity electric bridge
Bridge is completed, and with the optimization design of communication system, Two In and One Out electric bridge is born therewith.
Two In and One Out electric bridge in existing market is substantially a built-in ohmic load, to complete a radio frequency interface
Hypersorption, but due to the internal structure of the limitation of existing ohmic load and electric bridge limitation cause its mutual tone pitch excessively high,
Influence signal transmission quality.Therefore, it is necessary to propose a kind of new technical solution.
Invention content
The present invention proposes a kind of low intermodulation Two In and One Out electric bridge, solves signal transmission quality difference of the existing technology and asks
Topic.
To achieve the goals above, the technical scheme is that：A kind of low intermodulation Two In and One Out electric bridge, including shell,
First input adapter, the second input adapter and out splice going splice, the shell is interior to have coupler and accommodating cavity, and described first is defeated
Enter connector, the second input adapter and out splice going splice to be separately mounted on the side wall of the shell, and first input adapter,
Second input adapter and out splice going splice partly stretch into the coupler, are passed equipped with arranged in a crossed manner first in the coupler
Defeated line and second transmission line, are equipped with cable load in the accommodating cavity, and it is defeated that the both ends of the first transmission line are separately connected first
Enter connector and out splice going splice, the both ends of the second transmission line are separately connected the second input adapter and cable load.
Preferably, the shell includes that enclosure body and lid close the upper cover in the enclosure body.
Preferably, the cable load includes coaxial cable and wrapping post, and the coaxial cable is centered around the wrapping post
Periphery.
Preferably, the wrapping post is fitted between the enclosure body and upper cover.
Preferably, the end face of enclosure body contact opposite with the upper cover is equipped with waterproof construction.
Preferably, the waterproof construction includes waterproof groove and water proof ring, and it is recessed that the waterproof is protruded in the water proof ring part
Slot.
Compared with prior art, present invention tool has the advantage that：In low intermodulation Two In and One Out electric bridge proposed by the present invention, use
Cable load is come instead of traditional ohmic load, the mutual tone pitch of the reduction, and first transmission line arranged in a crossed manner and second are transmitted
Line is provided separately in coupler, and cable load is arranged in accommodating cavity, and so when in use, the two does not generate interference, this
Sample effectively increases signal transmission quality.Therefore, compared with prior art, the present invention has the advantages that signal transmission quality is good.
