Big technology or technology difficulty.Produce in enormous quantities and the use process of user in, there are still the risk of leak, to user or
User brings some potential safety problems；Meanwhile as shell sizes of the market to Switching Power Supply, charger, adapter are continuous
Reduce, the consistency problem in production will become more prominent, so that traditional shell waterproof technology using and pushing away
Extensively receive larger limitation.
Another traditional shell waterproof technology, is the bottom in upper and lower covers and line card interface, is filled in using glue
Its gap location, or in line card and outer cover body intersection the perfusion insulation AB glue of output line, waterproof is achieved the purpose that with this.This
The mode of kind waterproof, though the effect of waterproof can be functioned well as, as the glue and insulation AB glue of bonding, when having solidification
Between, the production capacity of production can be reduced, the dosage of glue is also difficult to control, it is more difficult to operation, i.e., enabled to solidify well, the production after solidification
Product are also easy to be influenced by factors such as mechanical oscillation, temperature, external force and gap location is caused to fall off, can still bring to user
Some potential safety problems.In addition, using cost brought by this technique, and the difficulty of batch production, can all have significantly
It is promoted；And the installation and the demolition and maintenance in later period of early period, there is bigger difficulty, does not meet the demand of economic benefit, Wu Fada
To ideal state, which also can not fundamentally solve the problems, such as shell waterproof.
Summary of the invention
The switch electricity that the object of the present invention is to provide a kind of suitable for communicating the fields such as communication, living electric apparatus, battery charging
Source, charger, adapter, converter etc. and it is reasonable in design, connection is reliable, waterproof performance is preferable, technological operation is simple, can

S2 the upper cover of convex multi-turn capillary groove and weld bond) is equipped with using the difference injection molding of dedicated injection mold and is equipped with convex
The lower casing of multi-turn capillary groove and weld bond；
S3) by the circuit board insertion lower casing for meeting electrical performance indexes, the output line for distinguishing positive-negative polarity is correspondingly welded to
Electrical connection is formed on circuit board；
S4) the line card by the upper cover of convex multi-turn capillary groove is equipped with and equipped with outer recessed multi-turn capillary groove, by supersonic direction, pressure
Enter in the convex multi-turn capillary groove of lower casing, and all components are put into ultrasonic particular manufacturing craft and carry out high temperature welding, forms one
The complete waterproof construction that all components are welded together.
Compared with prior art, the present invention having the advantage that
A kind of power supply casing structure of the present invention, reasonable in design, connection is reliable, and waterproof performance is preferable, low in cost,
Manufacture craft is simple, can automatic batch production.
Power supply casing structure of the invention is prevented including being equipped with the upper cover of convex multi-turn capillary groove, being equipped with outer recessed multi-turn
The line card of sink and lower casing equipped with convex multi-turn capillary groove, the outer recessed multi-turn capillary groove of line card end be accordingly pressed into upper cover and
The convex multi-turn capillary groove of lower casing, so that the output line and line card end that connect with circuit board are fixed in shell, and by upper
The weld bond on weld bond and convex multi-turn capillary groove that lid, lower casing edge are arranged, the welding by way of high-frequency high temperature welding
Together, to form a complete waterproof construction, it is equal to an one-time formed integral plastics component.Of the invention is anti-
Water-bound solves multicomponent and brought technology is used in combination under the premise of not influencing product overall appearance and electrical property
Problem and technology difficulty, efficiently solving between power supply body and output line due to mechanical clearance can not effective water proof and dust proof
Technology and production problem, avoid because the line card and shell of output line generate pine in the normal external force by user
It moves, misplace and cause the bad phenomenons such as poor contact and leak.Waterproof construction of the invention has the effect of good durable waterproof
Fruit, both not excessively high dimension precision requirement, did not needed to increase accessory part, also the requirement of not excessively high technique, just can reach yet
To good waterproof effect, and it can guarantee the plug performance of some strength.
