Abstract
The utility model discloses a cavity coupler, which comprises a cavity, a cavity cover, a first port, a second port, a third port, a transmission conductor and a coupling conductor, wherein the cavity cover is covered on the cavity to form an accommodating space with the cavity. The cavity of the cavity coupler is provided with positioning and fixing columns, the positioning and fixing columns are arranged at joints of the cavity and the cavity cover, and the cavity cover is provided with rivet holes matched with the positioning and fixing columns. The cavity coupler has the advantages that since the cavity of the cavity coupler is provided with the positioning and fixing columns, the cavity cover only needs to be covered on the cavity and positioned by using the positioning and fixing columns, and the cavity cover and the cavity can be riveted and fixed by flattening the positioning and fixing columns through a stamping process, thereby realizing the purpose of rapid assembly, and further improving the production efficiency.
Description
Technical field
The utility model relates to the mobile communication equipment technical field, relates in particular to a kind of cavity coupler for the signal of communication transmission.
Background technology
In the wireless mobile communications field, more and more extensive for the use of signal of communication transmission cavity coupler that signal of communication is distributed.Described cavity coupler generally comprises cavity, is placed on the chamber lid of described cavity, is arranged at transmission conductor and coupling conductors in described cavity, and three ports that are arranged on described cavity and are communicated with described cavity.Described transmission conductor and two ports wherein are connected to realize the transmission of signal of communication, and described coupling conductors is connected to realize the coupling of signal of communication with another port.
In the production process of cavity coupler, cavity and chamber lid need the auger shell hole, thereafter, chamber are placed on cavity, and the screw that passes cavity and chamber lid by screw is fixing by cavity and chamber lid.
Present stage, be screwed substantially cavity and chamber lid by manually completing with screw, and not only processing cost is high, and inefficiency.
Therefore, be necessary to provide a kind of improved cavity coupler to overcome above-mentioned defect.
The utility model content
The purpose of this utility model is to provide a kind of cavity coupler, in simple and convenient mode, cavity coupler is assembled.
For achieving the above object, the utility model provides a kind of cavity coupler, comprises cavity, chamber lid, the first port, the second port, the 3rd port, transmission conductor, coupling conductors; Described chamber is placed on described cavity and forms an accommodation space with described cavity, described transmission conductor, coupling conductors and load are arranged in described accommodation space, described the first port is arranged at respectively with the second port the both sides that described cavity is relative, and the two ends of described transmission conductor are connected with described the first port, the second port respectively, described the 3rd port and load are arranged at the opposite side of described cavity, and described coupling conductors is connected with described the 3rd port.
Wherein, the cavity of described cavity coupler arranges the location fixed leg, and described fixed leg is positioned at cavity and Gai junction, chamber, and described chamber covers the rivet hole had with described location fixed leg coupling.
The utility model has the advantage of: be provided with the location fixed leg on the cavity due to the utility model cavity coupler, only chamber need be placed on cavity, utilize this fixed leg location, location, to locate fixed leg by the punching press flow process afterwards flattens, being about to the chamber lid rivets with cavity, thereby realize the purpose of rapid-assembling, and then enhance productivity.
The accompanying drawing explanation
The cavity body structure schematic diagram that Fig. 1 is the utility model embodiment.
The cavity cap structure schematic diagram that Fig. 2 is the utility model embodiment.
Embodiment
In order to further illustrate the technical solution of the utility model, below in conjunction with embodiment, illustrate.
Shown in Fig. 1, a kind of cavity coupler, comprise cavity 1, chamber lid the 3, first port 5, the second port 6, the 3rd port 7, transmission conductor, coupling conductors; Described chamber lid 3 is placed on described cavity 1 and forms an accommodation space with described cavity 1, described transmission conductor, coupling conductors and load are arranged in described accommodation space, described the first port 5 is arranged at respectively the relative both sides of described cavity 1 with the second port 6, and the two ends of described transmission conductor are connected with described the first port 5, the second port 6 respectively, described the 3rd port 7 and load are arranged at the opposite side of described cavity 1, and described coupling conductors is connected with described the 3rd port 7.
Wherein, the cavity 1 of described cavity coupler arranges location fixed leg 2.
Shown in Fig. 2, have the rivet hole 4 with described location fixed leg 2 couplings on described chamber lid 1.
Shown in Fig. 1-2, in process of production, only chamber need be covered to 3 and be placed on cavity 1, utilize this location fixed leg 2 location, will locate fixed leg 2 by the punching press flow process afterwards and flatten, be about to chamber lid 3 and rivet with cavity 1, thereby realize the purpose of rapid-assembling, and then enhance productivity.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection range of claim of the present utility model.In addition, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
