Abstract

The invention relates to a small-volume planar cavity coupler which discloses a novel one-piece (together-piece) mounting mode of a connector and a coupler cavity, and belongs to research and development for a mobile communication enterprise. According to the small-volume planar cavity coupler, a coupler cavity, a cover plate and a connector are optimized, the overall size is designed to be 120*37*16.2mm, the cavity and the cover plate are subjected to special appearance functional design, and the design of the space size in the cavity and the prior art are realized together. The small-volume planar cavity coupler saves materials during work, reduces process steps, is stable in structure and easy to operate, and is mainly used as a coupler for indoor distribution coverage of cavity communication signals.

Description

Small size plane cavity coupler

Technical field

The present invention relates to a kind of coupler, be specifically related to a kind of small size plane cavity coupler, be mainly used in the indoor distribution covering of chamber signal of communication and use coupler.

Background technology

China Mobile market has become the whole world maximum mobile communication market and most important mobile communication product production base at present.But domestic mobile communication enterprise research and development ability is also more weak generally, and the local supporting rate of the components and parts of mobile communication equipment and parts is also lower.The operation of mobile communication 3G has simultaneously arrived the critical period, and telecommunications system reform etc. also brings new business opportunity for it.Development of Communication Technique is maked rapid progress, and the competition of coupler product is more and more fierce also, and the coupler product that is used for indoor distribution and base station is also increasingly high to the requirement of intermodulation index.

The following structure of the many employings of existing coupler on the market: overall dimension has 120*40*17, and 120*37*18, its inner surface are the plane; When die sinking die casting, use more material to cause that the product overall weight is heavier, cost is higher, and all be the substep hold-down screw in assembly connector, be difficult to guarantee the stability of product.

Summary of the invention

The object of the invention is exactly that a kind of novel connector and the coupler cavity that provide for the deficiency that solves prior art adopt same part (part altogether) mounting means, and structure is more firm, and performance is more stable, installs more convenient

The present invention realizes that through following scheme this coupler invention design is passed through coupler cavity, cover plate; The optimization of connector; At 120*37*16.2mm, to cavity, cover plate carries out particular appearance function design (Fig. 2 with the overall dimensions design; Fig. 3), cavity space size design and prior art realize jointly.

Cavity design shown in Figure 2: overall dimension 120*37*14.9, design can guarantee that N Connector 4 hole screws are installed in (same part) on the same cavity like this, is connected firmly, and is easy for installation;

Cover plate design shown in Figure 3, overall dimension 120*37*5, cover plate adopt stealthy step design, after cooperating installation with cavity, combine together, and outward appearance is neatly smooth, the leakage of the signal transmission that effectively reduces;

Connector shown in Figure 4 is that a kind of full pitch thread coupler is used N Connector, and flange size adopts 13.7*18, and mounting hole site adopts 9.3*13, and diameter is 2.8 hole.

The present invention has following beneficial effect in sum: the coupler cavity size is 120*37*16.2; Cavity, the optimal design of cover plate make that a kind of full pitch thread connector of installation is very convenient, save the operation of secondary installing, have saved assembly process, and Stability Analysis of Structures, easy operating.

Description of drawings

Fig. 1 is that novel coupler drawing is whole;

Fig. 2 is novel coupler cavity;

Fig. 3 is novel coupler cover plate;

Fig. 4 is that novel coupler is with the full pitch thread flange coupling connector of N type

Embodiment

N type A, category-B coupler process salt fog, high low temperature, after vibration waited test, performance index met the communications industry standard fully.

Fig. 4 connector is with M2.5*6 screw (3 place) on Fig. 2 cavity, and inside cavity adopts the prior art structure to realize function; Screw with M2.5*6 is installed in Fig. 3 cover plate on cavity Fig. 4; The connector that Fig. 4 requires is that a kind of full pitch thread coupler is used N Connector, adopts the flange of 13.7*18 to be fixed on Fig. 2 coupler cavity; Fig. 1 overall dimensions requires 120*37*16.5; Fig. 2 cavity, Fig. 3 cover plate is installed the back and is formed an integral body, and the cavity bossing is hidden in below the cover plate, does not influence outward appearance.

Claims (3)

1. be a kind of passing through to the coupler cavity, cover plate, the optimization of connector, at 120*37*16.2mm, to cavity, cover plate carries out the design of particular appearance function, and (Fig. 2, Fig. 3), cavity space size design and prior art realize jointly with the overall dimensions design.

2. small size according to claim 1 plane cavity coupler is characterized in that: save material, reduce operation, Stability Analysis of Structures, easy operating.

3. small size according to claim 1 plane cavity coupler is characterized in that: the coupler cavity size is 120*37*16.2; Cavity, the optimal design of cover plate make that a kind of full pitch thread connector of installation is very convenient, save the operation of secondary installing, have saved assembly process, and Stability Analysis of Structures, easy operating.
