Abstract
The utility model discloses an outdoor power divider. The outdoor power divider comprises a cavity and a plurality of connectors arranged in the cavity. The outdoor power divider further comprises a protecting crust. The protecting crust is arranged outside the cavity and the plurality of connectors. The protecting crust is provided with waterproof joints whose number is equal to that of the connectors. The waterproof joints are respectively electrically connected with the connectors. By adopting the outdoor power divider provided by the utility model, the protection level of the power divider is improved, and the requirement of outdoor usage is satisfied.
Description
Technical field
The utility model relates to the power splitter field, relates in particular to a kind of outdoor power splitter that is suitable for outdoor application.
Background technology
Power splitter is the common equipment of the communications field, is that two-way or multichannel output equate or the device of unequal energy for a road input signal energy is divided into.As shown in Figure 1, existing power splitter comprises cavity 11 and a plurality of connector, and connector comprises shell 14 and is arranged on the inner wire 13 in shell 14.Be provided with centre pilot 12 in cavity 11, the inner wire 13 of a plurality of connectors is threaded with centre pilot 12 respectively, and the shell 14 of a plurality of connectors is threaded connection and is fixed on cavity 11, between shell 14 and cavity 11, is provided with O RunddichtringO 15.This power splitter, all adopt and be threaded between the inner wire 13 of connector and centre pilot 12 and between the shell 14 of connector and cavity 11, therefore, can guarantee sealing effectiveness to a certain degree.But, there is certain interval and be difficult for installing additional sealing device between the inner wire 13 due to the shell 14 of connector and connector, therefore, existing power splitter degree of protection can only reach IP65 usually.
Existing this power splitter can also meet the protection needs when indoor use, and still, when when outdoor, because outdoor work environment is severe, therefore, its degree of protection does not often reach requirement, and device easily damages, and affects the useful life of power splitter.
The utility model content
For addressing the above problem, the utility model provides a kind of outdoor power splitter, and it can reach higher degree of protection, meets the outdoor application needs.
For achieving the above object, outdoor power splitter of the present utility model, comprise cavity and be arranged on a plurality of connectors on described cavity, described outdoor power splitter also comprises protecting crust, described protecting crust is arranged on the outside of cavity and described a plurality of connectors, be provided with the water joint identical with described connector quantity on described protecting crust, described water joint is electrically connected to each described connector respectively.
Preferably, the water joint that described water joint is degree of protection IP67.
Preferably, described protecting crust comprises drain pan and lid, and described lid is threaded connection and is fixed on drain pan, between described lid and drain pan, is provided with sealing joint strip.
Outdoor power splitter of the present utility model, the outer setting protecting crust at cavity and a plurality of connectors arranges water joint on protecting crust, and therefore, the barrier propterty of whole outdoor power splitter is improved.Especially adopt the water joint of IP67 degree of protection, can further guarantee the operational environment of cavity and connector.Outdoor power splitter of the present utility model, device is not fragile, can increase the service life.
The accompanying drawing explanation
The structural representation that Fig. 1 is power splitter in prior art;
The structural representation that Fig. 2 is the outdoor power splitter of the utility model.
Embodiment
As shown in Figure 2, outdoor power splitter of the present utility model comprises cavity 1 and is arranged on a plurality of connectors 2 on cavity 1 that a plurality of connectors 2 are threaded connection respectively and are arranged on cavity 1.This outdoor power splitter also comprises protecting crust 4, and protecting crust 4 is arranged on the outside of cavity 1 and a plurality of connector 2, is provided with the water joint 5 identical with connector 2 quantity on protecting crust 4, and water joint 5 is electrically connected to each connector 2 respectively.As shown in FIG., be provided with three connectors 2 on cavity 1, be provided with 5, three water joints 5 of three water joints on protecting crust 4 and be electrically connected to respectively with three connectors 2 by the wire 3 that is positioned at protecting crust 4.During use, protecting crust 4 matches with water joint 5, can improve the degree of protection of power splitter to meet the outdoor application needs.
Protecting crust 4 comprises drain pan 41 and lid 42, and lid 42 is threaded connection and is fixed on drain pan 41, between lid 42 and drain pan 41, is provided with sealing joint strip 6.Be that lid 42 can cover on drain pan 41, sealing joint strip 6 is arranged on the limit section that lid 42 is connected with drain pan 41, on lid 42, is provided with for lid 42 being fixed to the screw 7 on drain pan 41, and spring pad 8 and plain cushion 9 are installed on screw 7.
Protecting crust 4 of the present utility model is used in conjunction with water joint 5, has improved the degree of protection of power splitter.As of the present utility model a kind of preferred, the water joint that water joint 5 is degree of protection IP67.
This outdoor power splitter is carried out to waterproof and Dustproof experiment, experiment condition:
1, Dustproof experiment.Vacuum degree :≤2KPa (200mbar); Test duration: 8h; Test dust: talcum powder; Particle diameter distribution: 50um～1mm.
2, waterproof experiment.The immersion case, after immersion case size should make sample put the immersion case into, the sample bottom is at least 1m to the distance of the water surface, and the sample top is at least 0.15m to water surface distance; Test duration: 30min.
3, air-tightness experiment.Test pressure+52.3KPa, pressurize 3min, pressure drop is no more than 0.3KPa.
Experimental result:
Through experiment test, when using the water joint of degree of protection IP67, outdoor power splitter of the present utility model can reach the IP67 degree of protection, effectively protects the device of power splitter that it is not damaged.
