Abstract
The utility model relates to the field of techniques used in communications, in particular to a cavity filter, which comprises a cavity and a connector, wherein, the connector and the cavity are combined into a whole to improve the water resistance of the cavity filter. Compared with the procedurally complex conventional method of fixing the connector onto a housing through a bolt, the approach to configure the utility model is conducive to efficiency enhancement in mass production as a simple, time saving and labor saving technique.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of incorporating chamber fluid filter.
Background technology
Filter is widely used in the communications field as a kind of frequency selection device, especially field of radio frequency communication.Finish in the base station of signal emission and reception in communication system, filter is used to select signal of communication, clutter or interference signal that the filtering communication signal frequency is outer.
At present, in mobile communication base station system, generally use cavity body filter to come that antenna emission and the signal that receives are carried out frequency and select.Therefore, between cavity body filter and antenna, be provided for transmitting the connector of signal usually.As shown in Figure 1, it is the schematic diagram of the cavity body filter 100 that usually adopts of industry and the connector 200 that is connected with this cavity body filter 100.This connector 200 comprises outer conductor 210 and flange 220, this outer conductor 210 is the inner hollow shape, and the one end is connected with this flange 220, and this outer conductor 210 is one-body molded with this flange 220, makes this outer conductor 210 and flange 220 form common hollow bulb (not shown).The other end of this outer conductor 210 is provided with screw thread, is used for being connected with antenna end.This flange 220 is box-shaped, is provided with four through holes 221 around combining with outer conductor 210 on this flange 220.This cavity body filter 100 comprises cavity 120.Form chamber 110 on this cavity 120.On the sidewall 121 of this cavity 120, offer the perforation 121a that combines with the common hollow bulb of the outer conductor 210 of connector 200 and flange 220, and on sidewall 121 around this perforation 121a four through hole 221 positions of companion flange 220 be provided with four screw 121b.Four screws 300 pass institute respectively and reach through hole 221 and combine with described screw 121b, and then this connector 200 is fixed on the cavity body filter 100, hollow bulb on the connector 200 is communicated with perforation 121a, form unified hollow bulb, this is unified hollow bulb and is used for the mounted connector assembly.
Yet above-mentioned cavity body filter 100 is realized being connected by screw with connector 200, and each connector 200 all needs tool using that four screws 300 are screwed in corresponding screw 121b.Therefore, in large-scale production, need expend a large amount of time and manpower connector 200 is installed on the cavity body filter 100, be unfavorable for the raising of production efficiency.On the other hand, because base station system generally is exposed in the wild environment, for the cavity body filter 100 that is installed in the base station, it need have extremely strong water resistance.Usually, connector 200 is to realize with the cushion rubber at cavity 120 places of mutually combining of cavity body filter 100 by the flange 220 that is arranged on connector 200 with the waterproof of cavity body filter 100.Yet cushion rubber is in the wild environment, occurs easily wearing out, and then makes the water resistance variation.
The utility model content
In view of this, the invention provides the cavity body filter that a kind of water resistance is convenient to large-scale production well.
A kind of cavity body filter comprises cavity.This cavity body filter also comprises connector, and this connector and this cavity are one-body molded.
In the above-mentioned cavity body filter, described housing comprises a sidewall, and this connector is arranged on this sidewall.
In the above-mentioned cavity body filter, described this connector is cylinder type, and inside is hollow form.
In the above-mentioned cavity body filter, described cavity and connector adopt identical material to process.
In the above-mentioned cavity body filter, described identical material is an aluminium.
In the above-mentioned cavity body filter, described incorporate cavity and connector successively form through die casting and machining.
In the above-mentioned cavity body filter, this cavity and this connector are one-body molded, and then make the water resistance of this cavity body filter be better than the implementation of tradition employing connector partial installation on cavity body filter.The integrated cavity of this cavity body filter and connector are by adopting identical material elder generation after die casting and machining form; with respect to tradition with connector by the implementation of screw on housing; reduced installation procedure; save time and manpower, in large-scale production, help enhancing productivity.
Description of drawings
Fig. 1 is the schematic diagram of the cavity body filter that usually adopts of industry and the connector that is connected with this cavity body filter.
Fig. 2 is the partial schematic diagram of the cavity body filter of a better embodiment.
Embodiment
See also Fig. 2, cavity body filter 300 comprises cavity 320 and connector 330.Form chamber 310 on this cavity 320.This connector 330 is used for being connected with the antenna of base station system.
This cavity 320 comprises sidewall 321.This connector 330 is cylinder type, inside is hollow form, be arranged on this sidewall 321, and this sidewall 321 is provided with the perforation (not shown) with these connector 330 junctions, the hollow bulb of this perforation and this connector 330 forms unified hollow bulb in the lump, and this unified hollow bulb is used to assemble connector assembly.This connector 330 is provided with screw thread away from an end of cavity 320, is used for combining with antenna.This cavity 320 is formed in one with this connector 330, and then makes the water resistance of this cavity body filter 300 be better than the implementation of tradition employing connector partial installation on cavity body filter.
The integrated cavity 320 of this cavity body filter 300 and connector 330 by the block blank that adopts identical material such as aluminium through die casting, machining; with respect to tradition with connector by the implementation of screw on cavity 320; reduced installation procedure; save time and manpower, in large-scale production, help enhancing productivity.
