Description
Technical field
The utility model relates to a kind of waterproof constructions, more particularly, to a kind of waterproof construction for LED driver.
Background technique
The LED driver for seeing waterproof currently on the market is substantially the structure of full encapsulating, and waterproof substantially leans on colloid, end
Waterproof gasket between lid and shell.There are three problems in this way:
A: full encapsulating waterproof problem
Consider waterproof, therefore casting glue is full of entire shell as far as possible, water is allowed to be not easy to invade the part PCBA.But due to
Colloid and enclosure material difference, the coefficient of expansion is different, under the work of long-term high and low temperature alternative, will cause colloid and shell division,
The coefficient of expansion of general colloid is greater than shell simultaneously, causes casing deformation, cracking, to destroy fragile water proof environment.
B: waterproof purpose is not achieved in waterproof gasket processing difficulties
Waterproof between case body and end cap leans on waterproof gasket, is close in end cap, shell, waterproof gasket three by screwed lock
It connects, but waterproof gasket is soft body, in screw locking, waterproof purpose is not achieved in easily-deformable, rupture.Case body simultaneously
It is very thin, it is difficult to be bonded shell and end cap, position is easy partially, waterproof between shell and end cap to be not achieved.
C: the earthing of casing is bad
There is waterproof gasket between the shell and end cap of LED driver, shell shell end cap is soft connection.End cap connects the earth, outside
Shell shell connects the earth by end cap fixed screw.It is easy poor contact, special anodized rear end cap and shell are more difficult to reality
Existing good earth.
Product is as depicted in figs. 1 and 2 currently on the market, and wherein A is the cavity that silica gel is full of, and causes gasket to compress in this way
Amount is unable to control.
Utility model content
The purpose of this utility model is exactly to provide a kind of for LED drive to overcome the problems of the above-mentioned prior art
The waterproof construction of dynamic device.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of waterproof construction for LED driver, including waterproof end cover, waterproof gasket and waterproof shell, described is anti-
Water end (W.E.) is covered with the groove of a circle Yu waterproof shell interconnecting piece correspondingly-shaped, and the waterproof gasket is embedded in the trench.
Preferably, the groove side is equipped with the positive stop lug boss for the limit control of waterproof gasket decrement.
Preferably, the waterproof shell is equipped with radiating ribs, the radiating ribs and positive stop lug boss gun iron link.
Preferably, the radiating ribs are the limit point of waterproof end cover.
Preferably, the waterproof gasket is surrounded by four tapped through holes, and the waterproof shell corresponding position is also set
There is tapped blind hole, tapped blind hole is entered across tapped through hole by screw, waterproof gasket is fixed on waterproof shell.
Preferably, the waterproof gasket encloses the protection boss for protruding into waterproof shell equipped with one.
Compared with prior art, the utility model has the advantage that
1) because using non-full encapsulating, electron element and the certain expansion space of casting glue, weaken the expansion to shell and rush
It hits, the integrality of structurally waterproof is effectively ensured.
2) waterproof gasket considers certain deflection simultaneously, after the default deflection for reaching waterproof gasket, end cap and shell
Two metalwork gun iron links guarantee mechanical strength, good contact conducting.Waterproof gasket deflection is controllable, guarantees product manufacturing
Consistency, while waterproof gasket is constantly in controllable deformation range, is effectively blocked between the end cap of LED power and shell
Be machined gap, prevent the intrusion of water, and this deflection can overcome it is swollen caused by the different coefficients of expansion between shell and shell
Swollen gap.Accomplish waterproof by soft connection, ground connection leans on gun iron link.
