Abstract
The utility model provides a radio frequency remote unit with a short transmission path and better transmission performance, which comprises a case and a cavity filter fixed inside the case. An output interface of the cavity filter is connected with an N-type connector, a mounting hole is preliminarily arranged on the wall of the case, the N-type connector is fastened in the mounting hole, the output interface of the cavity filter is directly connected with one end of the N-type connector, at least one sealing ring is sleeved on the N-type connector, and a compression nut is arranged at the end of the N-type connector. The radio frequency remote unit solves the problem of signal loss caused by long signal transmission path and a large number of nodes after adopting cable component connection in the prior art due to the fact that the N-type connector is directly connected with the cavity filter inside the case of the radio frequency remote unit, and simultaneously provides more usable space for the inside of the case.
Description
Technical field
The utility model relates to a kind of Wireless Telecom Equipment Remote Radio Unit (RRU), and especially output port adopts the Remote Radio Unit of N Connector.
Background technology
Remote Radio Unit (RRU) is arranged between the portable terminal usually, link to each other with upper-level BTS by optical fiber, its effect be with upper-level BTS together under the control of base station controller, realize the reception and the emission of radio frequency signal.Remote Radio Unit is finished the radio frequency processing function, and it is in the end of wireless access network in network, directly finishes the communication with portable terminal.
In the traditional scheme, the cavity body filter of Remote Radio Unit is fixed in the cabinet, and an end of N Connector cable-assembly is connected on the cabinet, and interconnects by cable-assembly and cavity body filter.In such embodiment, the cavity body filter output port is long to the signal transmission path of RRU output port N Connector, node is many, transmission signals can lose, and to the quality and the performance requirement height of cable-assembly, cable is connected the space of the bigger operation of needs with cavity filtering output end mouth; Cable need be bent and influence the cable-assembly performance.
The utility model content
Main purpose of the present utility model provides that a kind of transmission path is short, the better Remote Radio Unit of transmission performance.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of Remote Radio Unit, comprise cabinet and be fixed on its inner cavity body filter, the output interface of cavity body filter is connected with N Connector, be preset with installing hole on the cabinet wall, described N Connector is connected in the installing hole, and the output interface of described cavity body filter directly is connected with an end of N Connector, be set with at least one sealing ring on the N Connector, the end of described N Connector is provided with clamp nut.
Described ring set is positioned at part outside the cabinet at N shape connector; The part that described N shape connector is positioned at cabinet inside also is provided with at least one sealing ring.
The sealing ring number that is positioned at cabinet inside and outside can be one, also can be for a plurality of, and its principle is similar with action effect.
What the utility model provided compares with Remote Radio Unit of the prior art, have the following advantages: because N Connector directly is connected at cabinet inside with cavity body filter, solve the available technology adopting cable-assembly and connected the loss of signal problem that the back signal transmission path is long, node is many and cause, simultaneously, provide bigger utilized space for cabinet inside.
Because ring set is positioned at the part outside the cabinet at N shape connector, the part that N shape connector is positioned at cabinet inside also is provided with at least one sealing ring, after adopting such structure, N shape connector firmly can be installed on the cabinet by locking nut, guarantee sealing of interface electromagnetic shielding and environmental sealing.
