N Connector
Technical field
The utility model relates to connector technique, particularly the technology of N Connector.
Background technology
The tradition N Connector occupation mode as shown in Figure 1: cavity body filter 7 is fixed in the cabinet 8, N Connector cable-assembly 5 one ends are fixed on the RRU port of cabinet 8, the other end is connected with output interface on the cavity body filter 7, and rubber washer 6 compacted backs supporting on the N Connector are to realize the degree of protection of IP67.Enforcement then makes the output port of cavity body filter 7 long to the signal transmission path of the N Connector of RRU port like this, node is many, transmission signals can lose, quality and performance requirement height to cable-assembly 5, the output port of the cable of cable-assembly 5 and cavity body filter 7 is connected the bigger exercisable space of needs, thereby and cable need be bent the performance that influences cable-assembly 5.
The utility model content
The purpose of this utility model is the shortcoming that signal transmission path is long, node is many when overcoming present N Connector and being connected with cavity body filter, and a kind of N Connector is provided.
The utility model solves its technical problem, the technical scheme that adopts is, N Connector, comprise the N Connector body, described N Connector body one end is provided with screw thread, it is characterized in that, also comprises inner wire and dielectric, described inner wire is arranged at the N Connector body interior by dielectric and protrudes in the N Connector body from a screw thread end far away, and described inner wire is connected with the output port of cavity body filter.
Concrete, also comprising square flange, described square flange is arranged on an end of giving prominence to the N Connector body on the N Connector body near inner wire.
Further, also comprise securing member, conductive seal circle, environmental sealing circle and circular flange dish, the circular flange dish is arranged on the N Connector body between screw thread and square flange, the conductive seal circle is arranged on the one side of circular flange dish near screw thread, the environmental sealing snare is at the end of screw thread near the circular flange dish, and securing member adapts with screw thread and contacts with the environmental sealing circle.
The beneficial effects of the utility model are, can make inner wire directly be connected with the output port of cavity body filter, signal transmission path is shortened, and no longer need cable-assembly, the loss of signal when as far as possible reducing transmission signals, and be screwed on cavity body filter by square flange, increase safety-type, make this N Connector more firm, the securing member, conductive seal circle, environmental sealing circle and the circular flange dish that increase, this N Connector is fixedly connected in the cabinet, it is fixed, increase fail safe.

Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model is provided with screw thread with N Connector body 1 one ends, it is inner and protrude in N Connector body 1 from screw thread 9 end far away that inner wire 11 is arranged at N Connector body 1 by dielectric 12, can make inner wire 11 directly be connected with the output port of cavity body filter 7, shorten signal transmission path, the loss of signal when as far as possible reducing transmission signals.
Embodiment
This routine N Connector also comprises square flange 13, described square flange 13 is arranged on an end of giving prominence to N Connector bodies 1 on the N Connector body near inner wire 11, its structure chart such as Fig. 2,3, its cutaway view such as Fig. 4, the schematic diagram that it is connected with cavity body filter such as Fig. 5, it is connected with cavity body filter and is installed in schematic diagram such as Fig. 6 on the cabinet.
At first screw thread is set at N Connector body 1 one ends, and it is inner and protrude in N Connector body 1 from screw thread 9 end far away that inner wire 11 is arranged at N Connector body 1 by dielectric 12, square flange 13 is arranged on the N Connector body 1 again and forms N Connector near an end of inner wire 11 outstanding N Connector bodies 1.This routine N Connector also comprises securing member 4, conductive seal circle 2, environmental sealing circle 3 and circular flange dish 10, wherein, circular flange dish 10 is arranged on the N Connector body 1 between screw thread 9 and square flange 13, conductive seal circle 2 is arranged on the one side of circular flange dish 10 near screw thread 9, environmental sealing circle 3 is enclosed within the end of screw thread 9 near circular flange dish 10, and securing member 4 adapts with screw thread 9 and contacts with environmental sealing circle 3.
Earlier the securing member on the N Connector 4, environmental sealing circle 3 are taken off during use; With the installing hole on the N Connector on the cavity body filter 7 (this N Connector is fixed on the cavity body filter 7 by square flange 13) the aligning cabinet 8, be installed in the cabinet 8 from cabinet 8 inboard insertions, and guarantee that conductive seal circle 2 closely contacts with cabinet 8 inwalls; Environmental sealing circle 3 is inserted on this N Connector body 1 from cabinet 8 outsides, and falls in the cabinet 8 outer wall mounting grooves; At last securing member 4 is screwed on the screw thread 9 on the N Connector body 1, and compresses environment sealing ring 3.
The utility model can be preferentially and particularly suitable but be not limited only to the outdoor and indoor Radio Frequency Subsystem of 3G (Third Generation) Moblie base station.
