Problems solved by technology
[0003] Most of the existing couplers on the market adopt the following structures: the outer dimensions are 120*40*17, 120*37*18, the inner wall of the cavity is not hollowed out, and the inner surface is flat; when opening the mold and die-casting, more materials are used As a result, the overall weight of the product is heavy and the cost is high, and the screws are fixed step by step when assembling the connector, which makes it difficult to ensure the stability of the product

Abstract
The invention discloses a concave surface cavity coupler connected with a connector via a flange and in a shared-piece manner, aiming at providing a novel way for installing the connector and a coupler cavity by the same piece (sharing one piece) for overcoming the defects in the prior art; the whole size of the coupler is designed to be 120*37*16.5mm by the optimization for the coupler cavity, a cover plate and the connector; special appearance function design (Figure 2 and 3) is carried out on the cavity and the cover plate; and the space size design of the cavity can be realized together with the prior art. According to the concave surface cavity coupler connected with the connector via the flange and in the shared-piece manner, the working cost is effectively saved, the structure is firmer, the performance is more stable, and the installation is more convenient; and the coupler can be mainly applied to mobile communication signal indoor distribution and coverage.
Description
Technical field [0001] The invention relates to a coupler, in particular to a concave cavity connector flange same-piece coupler, which is mainly used for indoor distribution coverage of mobile communication signals. Background technique [0002] At present, China's mobile communications market has become the world's largest mobile communications market and the most important production base for mobile communications products. However, the research and development capabilities of domestic mobile communication companies are generally still relatively weak, and the local matching rate of mobile communication equipment components and parts is still relatively low. At the same time, the operation of mobile communication 3G has reached a critical period, and the reform of the telecommunication system has also brought new business opportunities for it. With the rapid development of communication technology, the competition of coupler products is becoming more and more fierce, and the ...
