Description
Technical field
The invention belongs to outdoor power, electrical equipment or apparatus field, it is good and prevent that electronic devices and components are subjected to the outdoor application power supply can of stress damage and the encapsulating method of this shell to relate in particular to a kind of novel waterproof and dustproof, high-low temperature resistant, antiultraviolet, thermal conductivity.
Background technology
Along with the development of science and technology, people's work and life be unable to do without electric power.More and more to outdoor application power supply, electrical equipment or equipment, in the face of expose to the sun and rain, the test of the adverse circumstances such as wind and rain thunder and lightning, acid rain, humidity, thermal shock, outdoor application power supply, electrical equipment or equipment are had higher requirement, but most of power supplys and equipment all can't satisfy the needs of environment in outdoor application, number average is non-watertight mostly, antiultraviolet not, non-refractory, the bad phenomenon such as be not durable, device was lost efficacy by thermal shock, device is subjected to the stress infringement or inefficacy, life-span be short have perplexed the development of work and society always.
Existing outdoor LED outer casing of power supply generally adopts the materials such as metal plate such as iron plate, aluminium sheet, corrosion resistant plate to be squeezed into " returning " font structure, fixes with the side cover screw again.Because the degree of protection of outdoor power requires will accomplish more than the 1P65, so existing LED outdoor power shell all adopts the mode of embedding, the embedding filler mainly contains the filling of epoxy resin solid or the silica gel software is filled.
For example, the patent No. is that 201120473129 document discloses a kind of separated outdoor LED outer casing of power supply, comprise loam cake, the lower cover, the left cap that is connected with upper and lower covers respectively and the right cap that are connected with the mutual buckle of loam cake and inlay card in the sealing ring of side cover, it can adopt and be threaded.This utility model mainly adopts the mode of connector-a screw threads for fastening to fix, and structure comparatively simply is convenient to dismounting, in use need repairing if there is problem and also be very easy to, be convenient to the maintenance of later stage product, avoid occurring the outdoor LED of allowing power supply in the prior art will cut outer casing of power supply and cause the waste sheathing material in later maintenance problem.
Further, described loam cake comprises and the hook portion of the mutual buckle of described lower cover, the connecting hole that cooperates with described left and right side cap and the radiating ribs that places upper surface.Described lower cover comprises the draw-in groove with the mutual buckle of described loam cake, the connecting hole that cooperates with described left and right side cap and the radiating ribs of two sides.Be covered with radiating ribs and under be covered with radiating ribs, this radiating ribs can well be transferred to the heat that produces in the work of power supply inner member in the air rapidly, it is bad and affect the problem of power work, the useful life of having improved simultaneously power supply to have solved outdoor LED power supply heat sinking.
Described right cap that comprise connecting hole, two the line holes that are suitable for the sealing ring inlay card that cooperate with upper and lower cover and place the sidepiece low side with the stator location, outside, described stator is provided with two positioning through hole.Described sealing ring is provided with movable opening, line hole and the draw-in groove that cooperates with side cover.Described left cap comprise the connecting hole, that cooperates with upper and lower cover that be suitable for the line hole of sealing ring inlay card, a binding post and place the sidepiece low side with the stator location, outside, described stator is provided with two positioning through hole.Be equipped with stator on left cap and the right cap, this stator is provided with positioning through hole, the position of the outdoor LED power supply of the convenient fine setting of the design of through hole.
Because the degree of protection of outdoor LED power supply requires will accomplish more than the IP65 that therefore outdoor LED power supply need to adopt the sealing means of encapsulating.And this utility model has adopted split type design, in assembling process, first the lower connecting hole of left cap and first the alignment with the connecting hole of lower cover of lower connecting hole of right cap are installed and fixed, then the internal component of power supply is mounted on the inside of outer casing of power supply, first electric wire is passed after the line hole of sealing ring, inlay card is on left cap and right cap respectively with sealing ring again, and the power supply internal component is connected with outside by electric wire.After installing like this, directly the opening above outer casing of power supply carries out encapsulating.So the embedding process of outdoor LED power supply of the present utility model, can be fully by visually observing the encapsulating situation.This encapsulating mode can improve the encapsulating speed of product, the qualification rate of product and the production efficiency of power supply on the one hand; Can substantially avoid occurring leaking on the other hand the problem of glue or encapsulating deficiency.After encapsulating is finished, again the hook portion of loam cake and the draw-in groove of lower cover are fixed mutually, the position of fine setting loam cake with the upper connecting hole of the upper connecting hole of left cap, right cap with on the connecting hole that covers align, then fastening.The structural design of this outer casing of power supply guarantees the sealed circle of inner member of power supply and the inside that good encapsulating material is enclosed in outer casing of power supply, guarantees the performance of the water proof and dust proof protection against the tide of power supply.
The shortcoming that technique scheme exists is, because the glue cost of filling with is high, and encapsulating increases the product total weight, and the product weight heaviness causes cost of transportation to increase, maintenance difficult, and encapsulating operational difficulty etc. is perplexing the development of whole exterior product.
