A kind of power supply and waterproof electric power-feeding structure
Technical field
The utility model relates to a kind of electric supply installation.Specifically a kind of power supply.The utility model also relates to a kind of waterproof electric power-feeding structure simultaneously.
Background technology
Power supply adaptor, usually referred to as " power supply ", it is the power supply conversion equipment of electronic apparatus and portable electric appts, be usually used in mobile phone, notebook computer, electrical control equipment, LED light device etc., ac high voltage input power converts to and meets corresponding electronic product job requirement, the output of stable DC low-voltage by its effect.Power source internal is provided with operating circuit and protective circuit usually.In order to ensure the normal work of power supply, power supply need have good heat sinking function, to be distributed in time by the heat produced in power supply.
Due to reasons such as operational environments, many power supplys need be arranged in outdoor, moist environment or in water, such as, the driving power of outdoor LED or be arranged at the power supply of outdoor electric controling element, the power supply of the above-mentioned type not only will guarantee good radiating effect, also needs to have water-proof function, power source internal is entered to avoid the water source in rainwater or environment, cause the short circuit of power supply, burn power supply, even damage device corresponding to power supply.
China's Authorization Notice No. provides a kind of hermetically-sealed construction of outdoor water-proof power supply for CN203814097 utility model patent, comprise the shell of hollow, screw, be arranged on the end cap at shell two ends, outside four corners at described shell two ends, be respectively arranged with screwed hole disconnected with the inner chamber of shell; Inside described end cap described in each, be provided with waterproof foam, four corners of described waterproof foam and end cap are provided with the through hole corresponding with screwed hole; Waterproof foam and end cap are close to by the through hole of waterproof foam and end cap and screwed hole the two ends being fixed on shell by described screw.(documents is not write as the utility model, distinguishes with summary of the invention part) this patent makes end cap, waterproof foam and shell reach well to be close to fixing thus reaches good sealing effectiveness; Waterproof foam has good sealing and stability simultaneously, improves the water resistance of outdoor water-proof power supply.
But still there is following technological deficiency: first, the position that this patent needs water-tight to coordinate is more, namely need the position of carrying out water-tight process more, such as two end cap and shell, wire and two end cap all need to carry out water-tight process, so can cause complex structure, and the reliability of overall structure waterproof can be reduced due to many places water-tight process; Secondly, the position be sealed and matched is exposed to outside all the time, contacts with air.In the process of long term exposure, easily cause the quick aging such as wire, hermetically-sealed construction, thus cause integrally-built water resistance to decline, reliability is poor.Again, being arranged at outdoor power supply needs to be mounted on corresponding construction usually, and above-mentioned power supply needs, by the fixed installation of independent mounting structure, to make cost up, complex structure.
