Abstract

The utility model discloses a novel POI combiner system box, which includes a box body, a combiner is arranged in the box body, a through hole is opened on the box body, and the combiner passes through the through hole , connected with threaded connectors. The beneficial effect of the utility model is that it solves the shortcomings of the protection structure that can only be realized by connecting cables and adapters in the prior art, which has a great impact on the insertion loss and third-order intermodulation performance of the entire POI system. It has the characteristics of good three-order intermodulation, simple assembly, energy saving and environmental protection.

Description

A New Type of POI Combination System Chassis

technical field

The utility model relates to a casing protection structure, in particular to a novel POI combining system casing.

Background technique

At present, the box protection structure of the POI combiner system used in the prior art is to install a threaded connector on the box and connect it to the port of the combiner in the box through a cable. The third-order intermodulation difference and the loss of the whole system increase, the structure is complex and uncontrollable, and the primary pass rate is poor.

Contents of the invention

The purpose of this utility model is just to overcome above-mentioned shortcoming, designs a kind of novel POI combiner system chassis.

In order to achieve the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

A new type of POI combining system chassis, including a box body, a combiner is arranged in the box, a through hole is opened on the box body, the combiner passes through the through hole, and is connected with a threaded connector connected.

As a preferred solution, a waterproof gasket is provided on the threaded connector, and a gasket is provided between the combiner and the threaded connector, and is fixed by a nut.

As a preferred solution, the diameter of the through hole is larger than 17.5mm.

The beneficial effect of the utility model is that it solves the shortcomings of the protective structure realized by connecting cables and adapters in the prior art, which has a great influence on the insertion loss and third-order intermodulation performance of the entire POI system. Therefore, it has the characteristics of good three-order intermodulation, simple assembly, energy saving and environmental protection.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a partial enlarged view of the utility model.

Fig. 3 is a partially enlarged view of the utility model.

Among them, 1 is a threaded connector, 2 is a nut, 3 is a gasket, 4 is a waterproof gasket, 5 is a box, 6 is a combiner, 7 is an electric bridge, and 8 is a jumper.

detailed description

As shown in Figure 1, Figure 2, and Figure 3, put the waterproof gasket 4 on the threaded connector 1, then pass the threaded connector 1 through the through hole on the box body 5, and then put the gasket on the threaded connector 1 The piece 3 is screwed on the nut 2 and fastened to the threaded connector and fastened.

Applying the utility model to the signal coverage, since the threaded connector 1 and the box body 5 are sealed by the waterproof rubber ring 4 and then screwed and fastened, it fully guarantees good protection performance and has good third-order intermodulation and simple assembly ,Energy saving and environmental protection.

The structure in the figure is to cut away the box body 5 to show the mutual assembly and connection state of the threaded connector 1, the waterproof rubber ring 4, the gasket 3 and the nut 2.

The inner core of the threaded connector realizes the transmission of microwave signals in the form of coupling. A through hole with a diameter of 17.5mm is opened on the POI case, and a rubber sealing ring is put on the threaded connector on the combiner to pass through the through hole of the POI case, and a nut for an internal spring washer is added to the connector protruding from the outside of the case Fastening, enhanced protection performance.
