Description

Electronic component dustproof and waterproof structure

Technical field

The utility model relates to the water proof equipment of electronic component more particularly to a kind of electronic component dustproof and waterproof structures.

Background technique

It is universal with electronic product, electronic product using more and more.However, electronic product be most afraid of by aqueous vapor and It causes electronic component short-circuit, influences electronic product behaviour in service or even be easily damaged.Therefore it can be done in electronic product some anti- Water design usually utilizes coating or encapsulating, and especially one anti-water column of design is applied in circuit board, and being equipped on circuit boards can Power transformation hinders (VARIABLE RESISTOR), and in order to protect variable resistance, an anti-water column can be arranged on variable resistance for preventing Water penetrates into part.

Referring to Fig. 1, Fig. 1 is the perspective view of existing anti-water column, existing anti-water column 1 ' is by tube body 11 ' and 12 ' institute of waterproof plug Composition, wherein the waterproof plug 12 ' is additionally provided with waterproof ring 121 ' and positioning ring 122 '.In this way, when the waterproof plug 12 ' plug in When in the tube body 11 ', the waterproof ring 121 ' contacts at the 11 ' inner wall of tube body, and the positioning ring 122 ' corresponds to buckle In the positioning region of the tube body 11 '.

However, though existing anti-water column 1 ', which can pass through positioning ring 122 ', achievees the effect that stable waterproof plug 12 ' with positioning region, Waterproof plug 12 ' is allowed to reach the function of integrated molding and waterproof for convenience in existing anti-water column 1 ', the waterproof plug 12 ' is made Material is silica gel, rubber or other soft materials, and therefore, fixed effect may be influenced, and when entire When electronic device is placed in environment in the water of high pressure, the waterproof plug 12 ' will receive the pressure difference in water, so that waterproof plug 12 ' The phenomenon that generating sliding, and then the effect of existing anti-1 ' waterproof of water column is influenced, and existing anti-water column 1 ' is surveyed in foreign matter degree of protection Higher water proof and dust proof grade can not be obtained in examination, to be unable to satisfy specific products demand.

In addition, waterproof plug 12 ' can be influenced by positioning ring 122 ' and be can not be successfully from pipe when pulling out waterproof plug 12 ' The positioning region of body 11 ' is extracted, and pulling out firmly will cause the waterproof plug 12 ' and deform with positioning ring 122 ' influences waterproof effect in turn.

Therefore, via above description, the importance of anti-water column waterproof effect and pressure resistance can be learnt, it is desirable to provide high resistance to Pressure and fixed effect, at the same in the environment of high pressure, and can be avoided contact external dust and aqueous vapor, therefore, this is practical new Type inventor is strongly studied, and a kind of electronic component dustproof and waterproof structure of the utility model is completed in research and development finally.
