Abstract
The utility model provides a sealed structure for an outdoor waterproof power supply. The sealed structure comprises a hollow housing, screws and end caps disposed at two ends of the housing. The outer sides of four corners at the two ends of the housing are provided respectively with screw holes which do not communicate with a cavity of the housing. The inner side of each end cap is provided with waterproof foam. Through holes corresponding to the screw holes are disposed on the waterproof foam and the four corners of the end caps. The screws attach tightly and fix the waterproof foam and the end caps onto the two ends of the housing via the through holes and the screw holes of the waterproof foam and the end caps. The base material of the waterproof foam is chloroprene rubber. The beneficial effects are lie in that the sealed structure for the outdoor waterproof power supply allows the end caps, the waterproof foam and the housing to be closely attached and fixed so as to achieve excellent sealing effects; and meanwhile as the waterproof foam is excellent in sealing and stability, the waterproof performance of the outdoor waterproof power supply is improved.
Description
Technical field
The utility model relates to a kind of outdoor water-proof power supply, relates in particular to a kind of hermetically-sealed construction of outdoor water-proof power supply.
Background technology
At present, along with the fast development of electron trade, needing under many circumstances provides stable power supply to outdoor electronic product, for fear of short circuit and stable, requires outdoor power system to have higher water resistance.Classification of waterproof has reflected instrument protection against the tide and dustproof ability, and particularly in outdoor activities, in the unavoidable adverse circumstances in high humidity or many dirt sand, the sealing of instrument and waterproof ability are just most important for the safe handling and the life-span that guarantee instrument.In prior art, outdoor water-proof power supply main body adopts split-type structural, mainly by fluid sealant, carrys out waterproof, and its waterproof ability rank is relatively not high.Granted publication number: CN201976374U prospectus discloses the design that screwed hole is set at shell two ends corner, and screwed hole is communicated with shell inner cavity; Because connection easily causes screw corrosive wear, cause that immersion is in shell inner cavity, thereby affect internal circuit stability.In prior art, use casting glue can and end cap, often because encapsulating is inhomogeneous, easily causing coming off affects water resistance.
Utility model content
The utility model provides a kind of hermetically-sealed construction of outdoor water-proof power supply, reaches the technical problem that the waterproof rank of outdoor water-proof power supply is improved.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is:
The utility model provides a kind of hermetically-sealed construction of outdoor water-proof power supply, comprise hollow shell, screw, be arranged on the end cap at shell two ends, in four corners outsides at described shell two ends, be respectively arranged with the disconnected screwed hole of inner chamber with shell; In described end cap inner side described in each, be provided with waterproof foam, on four corners of described waterproof foam and end cap, be provided with the through hole corresponding with screwed hole; Described screw is close to by waterproof foam and end cap the two ends that are fixed on shell by through hole and the screwed hole of waterproof foam and end cap.
Further, the base material of described waterproof foam is neoprene; Neoprene has good physical and mechanical properties, and oil resistant is heat-resisting, resistance to combustion, resistance to daylight, resistance to ozone, acid and alkali-resistance, chemical-resistant reagent.
Further, the middle part of described waterproof foam and end cap is provided with the line three-way hole of crossing passing through for wire.
Further, in described line three-way hole arranged outside excessively, have the water joint being enclosed within on wire, effective anti-sealing seeps water from the space of mistake line three-way hole.
The hermetically-sealed construction of a kind of outdoor water-proof power supply that the utility model provides, the screwed hole of its outer casing end is arranged on the outside of four corners, makes end cap, waterproof foam and shell reach good sealing effectiveness; Screwed hole is not communicated with the inner chamber of shell, makes under the corrosion and abrasion condition of screw, and water also cannot infilter the inner chamber of shell from screw, improved the water resistance of waterproof power supply; Waterproof foam has good sealing and stability, for the water resistance of outdoor water-proof power supply provides safeguard.

Embodiment
Below in conjunction with accompanying drawing, specifically illustrate execution mode of the present utility model, accompanying drawing is only for reference and use is described, does not form the restriction to the utility model scope of patent protection.
The utility model provides a kind of hermetically-sealed construction of outdoor water-proof power supply, comprise hollow shell 1, screw 4, be arranged on the end cap 3 at shell 1 two ends, in four corners outsides at described shell 1 two ends, be respectively arranged with the disconnected screwed hole 5 of inner chamber with shell 1; In described end cap 3 inner sides described in each, be provided with waterproof foam 2, on four corners of described waterproof foam 2 and end cap 3, be provided with the through hole corresponding with screwed hole 5; Described screw 4 is close to by waterproof foam 2 and end cap 3 two ends that are fixed on shell 1 by through hole and the screwed hole 5 of waterproof foam 2 and end cap 3.The base material of described waterproof foam 2 is neoprene.The middle part of described waterproof foam 2 and end cap 3 is provided with the line three-way hole 7 excessively that confession wire 6 passes through.In described line three-way hole 7 arranged outside excessively, have the water joint 8 being enclosed within on wire 6, effective anti-sealing seeps water from the space of mistake line three-way hole.
The hermetically-sealed construction of a kind of outdoor water-proof power supply that the utility model provides, the screwed hole 5 of its shell 1 end is arranged on the outside of four corners, makes end cap 3, waterproof foam 2 and shell 1 reach good sealing effectiveness; Screwed hole 5 is not communicated with the inner chamber of shell 1, makes under the corrosion and abrasion condition of screw 4, and water also cannot infilter the inner chamber of shell 1 from screw 4, improved the water resistance of waterproof power supply; The base material that waterproof foam 2 is used is neoprene, has good sealing and stability, for the water resistance of outdoor water-proof power supply provides safeguard.
Above disclosed is only preferred embodiment of the present utility model, can not limit rights protection scope of the present utility model with this, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
