CN202855881U - Flange same-piece coupler of plane cavity connector - Google Patents

Abstract

The utility model discloses a flange same-piece coupler of a plane cavity connector, and belongs to a mobile communication device; the whole size of the flange same-piece coupler is designed to be 120*40*16.5mm by the optimization for a 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 in the cavity can be realized together with the prior art. According to the flange same-piece coupler of the plane cavity connector, the working cost is reduced, the assembly working procedure is omitted, and the installation is very convenient; and furthermore, the flange same-piece coupler is stable in structure and easy to operate, and can be mainly applied to mobile communication signal indoor distribution and coverage.

Description

A kind of plane cavity connector flange is with the part coupler

Technical field

The utility model relates to a kind of coupler, is specifically related to a kind of plane cavity connector flange with the part coupler, is mainly used in the mobile communication signal indoor distribution and covers.

Background technology

China Mobile market has become the whole world maximum Mobile Communications Market and most important mobile communication product production base at present.But domestic mobile communication enterprise the capacity of R﹠D 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 simultaneously operation of mobile communication 3G has arrived the critical period, and telecommunications system reform etc. also brings new business opportunity for it.The development of the communication technology is maked rapid progress, and the competition of coupler product is also more and more fierce, and the coupler product that is used for indoor distribution and base station is also more and more higher 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.

The utility model content

The utility model is realized by following scheme, this coupler utility model design is by the optimization to coupler cavity, cover plate, connector, overall dimensions is designed at 120*40*16.5mm, cavity, cover plate are carried out particular appearance Functional Design (Fig. 2, Fig. 3), cavity space size design and prior art realize jointly.

The purpose of this utility model is exactly that a kind of New connector and the coupler cavity that provide for the deficiency that solves prior art adopt same part (altogether part) mounting means, and structure is more firm, and performance is more stable, installs more convenient.

Cavity overall dimension 120*40*15.2, 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 outline size 120*40*5, cover plate adopt stealthy step design, combine together after cooperating installation with cavity, and outward appearance is neatly smooth, the leakage of the signal transmission that effectively reduces; Connector is a kind of full pitch thread coupler N Connector, and flange size adopts 13.7*18, and mounting hole site adopts 9.3*13, and diameter is 2.8 hole.

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 novel coupler with the full pitch thread flange coupling connector of N-type.

Embodiment

The design of this coupler utility model is optimized coupler cavity, cover plate, connector, concave surface cavity connector with the part coupler through salt fog, high low temperature, after vibration waited test, performance index met the communications industry standard fully.

The utility model provides a kind of New connector and coupler cavity adopts same part (altogether part) mounting means, cavity design overall dimension 120*40*15.2 shown in Figure 2, design can guarantee that N Connector 4 hole screws are installed in (same part) on the same cavity like this; Cover plate design outline size 120*40*5 shown in Figure 3, cover plate adopt stealthy step design, combine together after cooperating installation with cavity.

The connector that Fig. 4 requires is a kind of full pitch thread coupler N Connector, adopts the flange of 13.7*18 to be fixed on Fig. 2 coupler cavity; Fig. 1 overall dimensions requires 120*40*16.5; Fig. 2 cavity design N Connector 4 hole screws are installed on the cavity, form an integral body after Fig. 3 cover plate is installed, and the cavity bossing is hidden in below the cover plate, does not affect outward appearance.

Claims (3)

1. a plane cavity connector flange is the coupler that distributes and cover for mobile communication signal indoor with the part coupler, and it is comprised of novel coupler cover plate, cavity, the full pitch thread flange coupling connector of N-type.

2. a kind of plane according to claim 1 cavity connector flange is characterized in that with the part coupler: New connector and coupler cavity adopt with the part mounting means.

3. a kind of plane according to claim 1 cavity connector flange is with the part coupler, and it is characterized in that: N is complete, and pitch thread flange coupling connector 4 hole screws are installed on the same cavity.
