Abstract
The utility model relates to a cavity body circuit synthesizer with a sealing cover, which belongs to a cavity body circuit synthesizer used in the field of wireless communication. The utility model comprises a cavity body and a top cover, wherein the outer surface of the top cover is provided with the exposed end of a harmonic oscillation rod. The utility model is characterized in that the cavity body and the top cover are provided with a sealing cover, and the exposed end of the harmonic oscillation rod is sealed in the sealing cover. The design can prevent the exposed end of the harmonic oscillation rod from wind and rain erosion; the phenomena of signal distortion of the circuit synthesizer, the abandonment of the circuit synthesizer and the communication failure which are caused by the displacement and the deformation of the harmonic oscillation rod can be avoided, wherein the displacement and the deformation are caused by the collision of external force.
Description
Technical field
The utility model relates to a kind of cavity mixer of cavity mixer, especially with closure of wireless communication field use.
Background technology
China has had a plurality of mobile communications networks at present, comprises China Mobile Digital GSM, DCS net, the GSM of CHINAUNICOM, CDMA net etc., and the uplink and downlink signal distributions of these mobile communications networks is in different frequency ranges.Need to use mixer to merge, realize heterogeneous networks shared to antenna-feedback system and indoor distributed system by the Signal Separation of the different frequency range that will mix or with the signal that separates.Normally used mixer is the cavity mixer.This kind mixer includes cavity and top cover, and the outer surface of cap assembly exposes the end that resonant rod is arranged.Owing to outside an end of resonant rod is exposed to, be subject to erosion by wind and rain, rainwater infiltrates in the chamber; Even more serious is, as is subjected to the external force collision and makes resonant rod produce displacement, distortion, gently then can make the mixer distorted signals, heavy then mixer is scrapped, and causes communication failure.
Summary of the invention
In order to overcome the above-mentioned defective of existing cavity mixer, the utility model provides a kind of mixer, makes the exposed ends of resonant rod be subjected to seal protection, to avoid the collision of erosion by wind and rain and external force.
The technical scheme that its technical scheme that solves the utility model adopts is, the outside at the cap assembly of mixer increases a seal cover again, is closed originally being exposed to outer resonant rod.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the front structural map that the utility model cavity adds top cover.
Fig. 2 is the profile of Fig. 1 along A-A.
Fig. 3 is the front schematic view of the utility model seal cover.
Fig. 4 is the schematic perspective view of the utility model unencryption capping.
Fig. 5 is the schematic perspective view after the utility model adds seal cover.
Among the figure 1, cavity, 2, top cover, 3, seal cover, 4, the resonant rod exposed ends, 5, sealing strip, 6, screw.
Embodiment
In Fig. 1, Fig. 2, the cavity mixer mainly comprises cavity (1) and top cover (2), and cavity is made by a block of metal material, and the position of resonant cavity is reserved with some holes that are used to install resonant rod in the top cover respective chamber.The inboard, edge of cavity forms heavy stand rank, and top cover is installed on this step, makes the top cover outer surface apart from the cavity edge certain distance be arranged still, and purpose is that its exposed ends was no more than the cavity edge after resonant rod was installed.
Fig. 3 is the front schematic view of seal cover (3), is the metallic plate that a size equates with the cavity outer rim.
Fig. 4 shows that the top cover of cavity mixer has some resonant rod exposed ends (4) outward, and a circle sealing strip (4) is arranged on the cavity top edge.
Fig. 5 shows that seal cover passes through screw (5) and is connected with cavity.Resonant rod exposed ends (invisible among this figure) is sealed fully.
Another kind of embodiment of the present utility model is: seal cover (3) is not tabular, but shallow discoid.The cavity edge need not, or only presses top cover thickness.After seal cover was installed, resonant rod exposed ends (4) was sealed in the shallow discoid space of seal cover.
Claims (4)
1, a kind of cavity mixer of with closure comprises cavity, top cover, and the top cover outer surface has the resonant rod exposed ends, it is characterized in that, a seal cover is arranged on cavity and the top cover, in the resonant rod exposed ends is sealed in.
2, a kind of cavity mixer as the said with closure of claim 1 is characterized in that seal cover is a shallow discoid, and after seal cover was installed, the resonant rod exposed ends was sealed in the shallow discoid space of seal cover.
3, a kind of cavity mixer as the said with closure of claim 1, it is characterized in that, seal cover is tabular, the inboard, edge of cavity forms heavy stand rank, top cover is installed on this step, the top cover outer surface still has certain distance apart from the cavity edge, and resonant rod exposed ends height is no more than the cavity edge.
4, a kind of cavity mixer as claim 1 or 2 or 3 said with closures is characterized in that having between cavity edge and the seal cover sealing strip.
