Description
Technical field
This utility model relates to a kind of combiner, and in particular, it relates to a kind of water proof type combiner.
Background technology
In radio handset communications system, combiner Main Function is to be combined to together by the signal of the multiband of input
Output road is in same set of indoor distributed system.In engineer applied, need by the C net of 800MHZ, the G net of 900MHz or
Other different frequencies export simultaneously, use combiner, a set of indoor distributed system can be made to simultaneously work in CDMA frequency range, GSM
Frequency range or other frequency ranges.As in radio antenna system, (such as 145MHZ and 435MHZ) of several different frequency ranges is inputted
After output signal closes road by combiner, being connected with radio station with a feeder line, this has not only saved a feeder line, also avoid and cuts
Change the trouble of different antennae.
Combiner typically has two or more input port, only one of which output port.Interport isolation is one and compares
Important index, for describing the ability that two paths of signals is independent of each other, typically requires at more than 20dB.
Along with No.3 generation mobile communication system and the Large scale construction of forth generation mobile communcations system, in-door covering is distributed
The construction scale of system is increasing, and indoor combiner closes the Primary Component on road as the most each standard information source, and application is increasingly
Extensively.But owing to building diversification and the diversity of territorial environment of scene, indoor combiner is to environmental suitability difference
Problem comes out, and cannot meet moving communicating field to product high-performance and long-life demand.Existing combiner
Shown in as disclosed in the Chinese patent that Authorization Notice No. is CN201868546U, it includes casing, adjusting screw rod, resonant rod and connects
Line mouth, resonant rod is arranged on box bottom inwall by securing member, and adjusting screw rod passes casing water proof type combiner panel, inserts
Resonant rod opening, connection jaws is positioned at casing front-rear side walls, and described securing member does not pass box bottom water proof type combiner；Along casing
The surrounding of panel is additionally provided with the capillary groove of annular, is provided with a water proof ring in capillary groove water proof type combiner, and capillary groove top sets
The first cover plate, the first cover plate is had to compress water proof ring and are tightly connected with capillary groove.
But although this combiner is provided with water proof ring, but in actual use, often due to sealing ring and case lid
Laminating defective tightness, cause its sealing poor, and then cause its waterproof effect the best.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of sealing effectiveness more preferable, thus
Make the more preferable combiner of its waterproof effect.
For achieving the above object, this utility model provides following technical scheme: a kind of water proof type combiner, including casing
And case lid, it being provided with some resonant rods in described casing, the periphery of the opening of described casing is provided with a ring groove, described annular groove
Inside being connected with annular seal ring, be provided with the reed of arc in described annular seal ring, described case lid includes cover plate and is arranged on
One circle side plate of cover plate periphery, when described case lid covers on described casing, the side plate of described annular seal ring and described case lid
Inwall laminating and described reed are exceptionally straight.
By using technique scheme, when case lid covers on casing, annular seal ring can be provided as using supporting of reed
The lower sidewall with the side plate of case lid fits tightly, thus improves its sealing, and then improves the water proofing property of this combiner.
It is also preferred that the left the cross section of described annular seal ring be I shape arrange and include external seal sheet, interior diaphragm seal and
For connecting the connection sheet of described external seal sheet and interior diaphragm seal, described reed is arranged on the external seal sheet of described annular seal ring
In.
By use technique scheme, cross section be I shape arrange annular seal ring elastic deformability more
Good, so that the sealing effectiveness of annular seal ring is more preferable, and then improve the water proofing property of this combiner.
It is also preferred that the left be provided with anticreep groove in described annular groove, described annular seal ring is provided with and described anticreep slot fit
Anti-delinking part.
By using technique scheme, it is to avoid the when of opening case lid, cause ring-type close due to close adhesive force
Seal departs from annular groove, and the setting so making annular seal ring is more firm.
It is also preferred that the left described anti-delinking part is barb-shaped setting and anti-drop block integrated with described annular seal ring.
By using technique scheme, it is simple to manufacture, low cost, and good anti-drop effect.
It is also preferred that the left the outside of described external seal sheet and interior diaphragm seal is provided with anti-delinking part, be provided with in described annular groove with
The anticreep groove that described anti-delinking part coordinates.
By using technique scheme so that the anticreep effect of annular seal ring is more preferable.
It is also preferred that the left described anti-delinking part is barb-shaped setting and anti-drop block integrated with described annular seal ring.
By using technique scheme, it is simple to manufacture, low cost, and good anti-drop effect.
In sum, this utility model has the advantages that 1. casings of the present utility model compared to prior art
With the good airproof performance of case lid so that its water proofing property is more preferable；2. this utility model is simple to manufacture, low cost.
