7, by the fan-free Switching Power Supply of a kind of rain-proof type described in 1, it is further characterized in that the lower mouth of boxboard 2 is stained with insulating film 2-6 enhances the insulation of wiring window.

The application of common outdoor switch power supply is summarized:

A, a kind of to be used for cubicle switch power supply, in Switching Power Supply Rainproof case, radiating requirements are answered, Rainproof case opens up blinds Rain-screening aeration hole adapts to the needs of outdoor environment, and structure is complicated.

B, a kind of outdoor switch power supply, side are equipped with dedicated fan heat dissipation channel, lower part wiring, bottom end-cover-free and cable Protection pipe connection setting.

C, a kind of outdoor switch power supply, it is fan-free, by aluminum hull heat dissipation, lower part wiring, bottom end-cover-free and cable protection pipe Connection setting, lower part connecting part have protection flip lid or upward pushing cover.

D, a kind of outdoor switch power supply, fan-free, lower part uses dedicated connector, and integrally reaching bottom has end cap and cable Protection pipe connection setting, lower part connecting part have protection pushing cover, are able to satisfy every technical requirements, structure is complicated.

The pros and cons of above-mentioned four kinds common outdoor switch power supply applications:

1) A scheme, cubicle switch power supply is used for open air after refilling in Rainproof case, increases the workload of installation, high-power Have fan, the service life of fan is lower than other devices in general Switching Power Supply, the fan part service life determine equipment service life, and There is the fan running sound.

2) B scheme has dedicated fan, identical as A scheme, and the fan part service life determines the service life of equipment, and has fan The sound, while bottom end-cover-free and cable protection pipe connection setting are operated, there are security risks.

3) C scheme, bottom end-cover-free and cable protection pipe connection setting, lower part connecting part have protection to renovate or push up Lid；Bottom end-cover-free and cable protection pipe connection setting simultaneously, there are security risks；Lower part connecting part has protection flip lid or upward Pushing cover, in debugging and maintenance, protection cap, which loosens, is easy to influence operation, while because with aluminum conductive cap, conductive protection cap is held It is easily brushed up against by tool, the safety accident for leading to short circuit is easily caused to occur.

4) D scheme, is integrally able to satisfy every technical requirements, but due to being two large divisions's composition, more two parts connection dresses It sets, overall stiffness and heat dissipation are slightly lower, and structure is relative complex, and manufacturing cost is higher, it has not been convenient to whole factory.

The present invention is compared with existing situation:

1) fan-free Switching Power Supply and terminal box integrated design are used, heat dissipation ventilation is strengthened, extends power supply Bulk life time；End cap and cable protection pipe connection setting are arranged at bottom, eliminate security risk.

2) cover board 5 of 1 lower part of shell takes out structure using drop-down, and the lower mouth of boxboard 2 is stained with insulating film 2-6, enhances wiring Tool is not easy to brush up against cover board 5 when the insulation of window, debugging and maintenance, avoids the security risk that may cause short circuit when tool operation Occur.

3) for convenience of overhauling, respectively there are a lanyard holes on shell 1 and cover board 5, couple with rope, can prevent installation or Cover board 5 is fallen when maintenance.

4) cover board 5 is fixed on shell 1 using briquetting 6, and when removing cover board 5 from and being fastened on shell 1 with screw, device to hole occurs The case where position is difficult and easily falls screw generation, improves operating efficiency.

5) overall stiffness and thermal diffusivity are high, and structure is relatively easy, and manufacturing cost is lower, facilitates whole factory.
