Be formed with a flange on the described waterproof pad, the exterior contour of this flange is corresponding with cylindrical body intracavity section shape.
Described baffle plate is provided with a boss that is solidified as a whole with baffle plate towards the end face of cylindrical body; Offer through hole and the scarce hole passed for lead on baffle plate and the boss.
Described seal comprises the collar that is arranged on the baffle plate through hole and is arranged on the sealing ring that boss lacks the place, hole.
Described collar has been formed along a circumference thereof a draw-in groove, and the inner edge inlay card of through hole is in this draw-in groove; Described sealing ring shape is corresponding with the shape that boss lacks the hole, and the end face of its relative collar one side forms the depressed part corresponding with the collar profile, and forms a groove in the depressed part outer rim.
The place, scarce hole of described boss is fixed with a securing member, and sealing ring is limited to by securing member and lacks in the hole; Offer the through hole that passes for lead on this securing member, be formed with the adapter sleeve that lead is carried out clamping in this through hole edge.
Form screwed hole on the left and right sides through hole end face of described cylindrical body, this screwed hole is positioned at the fin place, and baffle plate was fastened on the cylindrical body by screw and cooperating of this screwed hole.
Described baffle plate is formed with a kink, offers fixing hole on this kink, by this fixing hole entire product is fixed on other facilities, the device.
After the present invention had adopted technique scheme, it had following advantage:
1, the main body of shell of the present invention adopts the cylindrical body section bar that once forms, and the baffle plate encapsulation is adopted at the main body two ends, so both can guarantee the sealing of product, and the while also has good but thermal effect.
2, heat-conducting metal body on the circuit board of the present invention and shell are fitted, and can in time shed to make the heat on the circuit board.
3, adopt hermetically-sealed construction between baffle plate of the present invention and the cylindrical body, guarantee the sealing of the two.
4, among the present invention, when lead passes baffle plate, adopted special hermetically-sealed construction, can guarantee drainage can not occur, further guaranteed the sealing of product at the lead place.
In sum, the present invention directly adopts the structural formula sealing, and the sealant pouring and sealing in the non traditional product, its production cost can reduce greatly, and production technology is simplified.Another aspect, adopt this structure after, product can be dismantled, and is convenient to renewal part, element, reduces product and scraps because of minor issue.
Description of drawings:
Fig. 1 is an internal structure schematic diagram of the present invention;
Fig. 2 is a three-dimensional exploded view of the present invention.
Embodiment:
Below in conjunction with accompanying drawing this full mold is further described:
See Fig. 1-2, the present invention includes: shell 1 and the power supply main body 2 that is installed in the shell 1.
Form draw-in groove 112 on the two relative inwalls in the cylindrical body 11, this draw-in groove 112 is used for the circuit board 21 of power supply main body 2 and installs.
Power supply main body 2 comprises: circuit board 21, be fixed on heat-conducting metal body 22 and lead on the circuit board 21.Circuit board 21 adopts printed circuit board (PCB), and it inserts in the draw-in groove 112 of above-mentioned cylindrical body 11 inwalls, by draw-in groove 112 location.Heat-conducting metal body 22 is the body and function aluminum alloy materials also, and it is fixed on the circuit board 21, and this heat-conducting metal body 22 and the applying of cylindrical body 11 inwalls, and fixes by screw and cylindrical body 11 sidewalls.Owing to adopt screw, need on cylindrical body 11, offer screwed hole, screw and screwed hole assembling place drainage can not occur in order to go bail for.After screw passes cylindrical body 11 sidewalls and heat-conducting metal body 22 is threaded, offer the position of screwed hole at cylindrical body 11 sidewalls and adopt the fluid sealant water-stop, screw and screwed hole are got up than encapsulation entirely, guarantee can not occur infiltration.During renewal part, only need the encapsulation glue strip off at this screw place is got final product if desired.
Waterproof pad 3 is between baffle plate 12 and cylindrical body 11.In order to ensure the sealing effectiveness of waterproof pad 3, on waterproof pad 3, be formed with a flange 31, the exterior contour of this flange 31 is corresponding with cylindrical body 11 intracavity section shapes, improves sealing effectiveness by this flange.
Above-mentioned baffle plate 12 is provided with a boss 121 that is solidified as a whole with baffle plate 12 towards the end face of cylindrical body 11, and the shape of this boss 121 is consistent with marine glue 3 internal bore profile.Like this, when baffle plate 12 cooperated with cylindrical body 11, above-mentioned waterproof pad 3 inner edges just in time were set on the boss 121, form good closely cooperating.
On baffle plate 12 and boss 121, offer through hole 120 and the scarce hole 122 passed for lead.The seal 4 that lead in the power supply main body 2 passes on shell 1 baffle plate 12 connects with the outside.Sealing part 4 comprises: be arranged on the collar 41 at baffle plate 12 through holes 120 places and be arranged on the sealing ring 42 that boss 121 lacks 122 places, hole.
