Embodiment
The detailed description of relevant the utility model and technology contents, schema is coordinated to be described as follows, but institute's accompanying drawings only carry
Used for reference with explanation, be not used for being any limitation as the utility model.
As shown in Figures 3 to 6, the utility model provides a kind of electronic device construction, including a shell 110, a circuit board
160th, a fluid sealant 180 and an encapsulating 190.Electronic installation 100 described herein preferably turns including but not limited to voltage device, power supply
The related electronic installation such as parallel operation.
Shell 110 offers at least one perforation 120, and it can be made by plastic cement, metal, metal alloy or its combination.Outside
Shell 110 also has two flanges 130, the convex hull 140 being arranged between two flanges 130 and the accommodating sky in convex hull 140
Between 150.Circuit board 160 at least one comprising the multiple electronic components 162 of electric property coupling and the setting of relatively at least one perforation 120 is electrical
Connection end 170.In the present embodiment, shell 110 preferably offers perforation 120 corresponding to two-phase, relative two perforation of circuit board 160
120 include two electricity connection ends 170.Signified electricity connection end 170 preferably refers to a connector herein；But at other
In different embodiments, electricity connection end 170 also can be some electrically pins, an electric wire or other suitable electric connection members
Part, do not limit.Species and quantity about each electronic component 162 regard different electronic installations 100 and changed, therefore herein not
Separately repeat.
In such as Fig. 4 and Fig. 5, each electronic component 162 is preferably respectively contained in accommodation space 150, and accommodation space 150 is also
Filled with encapsulating 190, therefore each electronic component 162 of circuit board 160 and its solid welding can effectively be solidified and determined by encapsulating 190
Position.Perforation 120 is formed at flange 130, makes preferably to be, for example, that the electricity connection end 170 of connector passes and exposed from perforation 120
Outside convex hull 140.Two sides of perforation 120 have been also respectively connected with a dividing plate 134, and flange connector 130 is distinguished in each both sides of dividing plate 134
With the side wall of convex hull 140, further to limit the displacement of electricity connection end 170.
Fluid sealant 180 is arranged between each circuit board 160 and each perforation 120.In other words, when fluid sealant 180 is coated on electricity
After between road plate 160 and each perforation 120, the electricity connection end 170 of for example, connector can plug perforation 120 and be positioned at two
Between dividing plate 134, the impurity such as aqueous vapor, dust is not penetrated into from perforation 120, avoid each electronics member on circuit board 160
Part 162 damages or failure, and then lifts the service life of electronic installation 100.
A gap 210 is also included between bottom plate 200 and circuit board 160, encapsulating 190 is more filled in gap 210.Therefore work as
When encapsulating 190 is filled in the gap 210, equally has and the stabilization of circuit board 160 is fixed on the effect of bottom plate 200, and make
The impurity such as aqueous vapor, dust will not penetrate into from the gap of bottom plate 200 (figure omits).Bottom plate 200 can be plastic cement, metal, metal alloy or
Made by it is combined, the curable formation matrix such as collision mat or waterproof gasket after solidifying of encapsulating 190, with reach waterproof with it is solid
The effect of determining.
In addition, the elastic button hook that at least opposite sides of bottom plate 200 is set also comprising side plate 222 and in side plate 222
220.The two flanges 130 of shell 110 also offer a positioning hole 132 respectively, for engaging with each elastic button hook 220.In such as Fig. 3 extremely
In embodiment shown in Fig. 5, bottom plate 200 is preferably provided with four corresponding side plates 222, and is equipped with the bullet per side plate 222
Property button hook 220, to engage with corresponding each positioning hole 132.The stability that bottom plate 200 engages with shell 110 can so be increased
With reliability.
Therefore, each electronic component 162 of the solid welding of the utility model circuit board 160 is adapted to for example, connector or other
The electricity connection end 170 of element, therefore be not necessary to the welding processing procedure by tin stove, that is, the procedure by secondary welding is not necessary to,
Circuit board 160 and each electronic component 162 thereon will not produce the phenomenon to melt down because of high temperature.In addition, be coated on circuit board 160 with
Fluid sealant 180 between perforation 120 and it is coated on the encapsulating 190 in accommodation space 150 and gap 210 and will not also produces excessive glue etc.
The problem of pollution, electronic installation 100 of the present utility model is set not produce any clearance or gap, aqueous vapor and dust etc. will not
Its from there into, and then lifted electronic installation 100 quality and service life.
In summary, it should be considered as in the embodiment disclosed in this illustrating the utility model herein, and be not used to limit
The utility model processed.The scope of the utility model should be defined by rear attached claim, and cover its legal equivalents, and
