Problems solved by technology

Electronic appliances with waterproof function are required when used outdoors and in low water. Most of the current waterproof casings are potted with glue or epoxy resin; this will greatly affect the heat dissipation of the electronic components inside the appliance, thus Reduce the reliability of the product and shorten the life of the product
Furthermore, some heating elements will be damaged when the epoxy resin is heated and deformed, which will further affect the reliability of the product

Abstract

The invention relates to a waterproof electrical-appliance shell which comprises an upper shell, a lower shell, a left end cover and a right end cover, wherein the upper shell, the lower shell, the left end cover and the right end cover are installed into a whole. The waterproof electrical-appliance shell is characterized in that the edges of the upper shell and the lower shell are overlapped together, the overlapping surfaces of the upper shell and the lower shell are mutually corresponding circular-arc surfaces, and a waterproof strip is clamped inside the combined part of the upper shell and the lower shell; and a waterproof sealing pad is respectively clamped between the end surfaces of the upper shell and the lower shell and the end covers, and the end covers and the waterproof sealing pads are connected with and fixed at the end parts of the upper shell and the lower shell through screws. The waterproof electrical-appliance shell provided by the invention has the advantages thatthe waterproof electrical-appliance shell has an artful structure, not only has a good waterproof function, but also can be used for emitting the heat inside the shell to the outside of the shell through an aluminum alloy, does not have a series of troubles brought by using epoxy resin for filling and sealing, is also quite convenient to install and produce, is safe and reliable and has long service life.

Description

(1) Technical field [0001] The invention belongs to the casing junction method of electric appliances, and relates to a waterproof electric casing. The main feature is that it has a good waterproof function, and is widely used in the shells of electronic ballasts for electrodeless lamps, LED power supplies, power adapters, chargers and other electronic appliances. (2) Background technology [0002] With the increasing development of electronic technology, electronic products such as switching power supplies, electronic ballasts, and chargers are widely used. Electronic appliances with waterproof function are required when used outdoors and in low water. Most of the current waterproof casings are potted with glue or epoxy resin; this will greatly affect the heat dissipation of the electronic components inside the appliance, thus Reduce the reliability of the product and shorten the life of the product. Furthermore, some heating elements will be damaged when the epoxy resin ...
