Abstract
The utility model discloses a novel POI close way system machine case, the power distribution box comprises a box body, be provided with the combiner in the box, it has the through -hole to open on the box, the combiner passes the through -hole is connected with screw connector. The beneficial effects of the utility model reside in that, solved the protective structure that could realize through connecting cable and adapter among the prior art, to the insertion loss of whole POI system, index performances such as third order intermodulation have the shortcoming of very big influence. Have that third order intermodulation is good, the assembly is simple, characteristics such as energy -concerving and environment -protective.
Description
Technical field
This utility model relates to a kind of cabinet safeguard structure, particularly relates to a kind of novel POI and closes road system chassis。
Background technology
At present, it is install to turn screw thread coupling and be connected with Combiner port in cabinet by cable on cabinet that the POI that prior art uses closes road system chassis safeguard structure。Third order intermodulation difference and whole system loss increase, and the complicated uncontrollable first-time qualification rate of structure is poor。
Summary of the invention
The purpose of this utility model is that and overcomes disadvantages mentioned above, designs a kind of novel POI and closes road system chassis。
In order to realize foregoing invention purpose, this utility model adopts the following technical scheme that
A kind of novel POI closes road system chassis, including casing, is provided with combiner in described casing, described casing has through hole, and described combiner, through described through hole, is connected with screw thread coupling。
Preferably, described screw thread coupling is provided with waterproof washer, is provided with pad between described combiner and screw thread coupling, and is fixed by nut。
Preferably, the diameter of described through hole is more than 17.5mm。
The shortcoming that the index performances such as the beneficial effects of the utility model are in that, solve by connecting the safeguard structure that cable and adapter could realize in prior art, the insertion loss to whole POI system, third order intermodulation have a significant impact。Therefore there is the features such as third order intermodulation is good, assembling is simple, energy-conserving and environment-protective。
Accompanying drawing explanation
Fig. 1 is this utility model structural representation。
Fig. 2 is this utility model partial enlarged drawing。
Fig. 3 is this utility model partial enlarged drawing。
Wherein, 1 is screw thread coupling, and 2 is nut, and 3 is pad, and 4 is waterproof washer, and 5 is casing, and 6 is combiner, and 7 is electric bridge, and 8 is wire jumper。
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, waterproof washer 4 is set on screw thread coupling 1, afterwards by screw thread coupling 1 through the through hole on casing 5, on screw thread coupling 1, is then inserted in pad 3 screws on nut 2 and be fastened on screw thread coupling and fasten。
This utility model is applied to during signal covers, owing to screw thread coupling 1 and casing 5 adopt waterproof apron 4 to seal the mode of screw threads for fastening, has fully ensured that good barrier propterty has that third order intermodulation is good, assembling is simple, energy-conserving and environment-protective simultaneously again。
Structure in figure is to cut casing 5 open, it is shown that screw thread coupling 1, waterproof apron 4, pad 3, nut 2 mutually assembling and connection status。
Described screw thread coupling inner core realizes the transmission of microwave signal with the form of coupling。Opening the through hole that diameter is 17.5mm on POI cabinet, the screw thread coupling on combiner puts the rubber seal through hole through POI cabinet, adds the fastening of internal tooth spring washer nut, strengthen barrier propterty on the adapter stretching out outside cabinet。
Claims (3)
1. novel POI closes a road system chassis, including casing, it is characterised in that be provided with combiner in described casing, described casing has through hole, and described combiner, through described through hole, is connected with screw thread coupling。
