A kind of and aluminium electrolutic capacitor for preventing electrolyte splash.
Background technology
LED illumination is widely promoted as fourth generation of new light source in major lighting field, and LED illumination market is quick
Development, the unprecedented opportunity to develop that the field welcomes, the market demand is huge, while in order to preferably service lighting field,
Low cost, miniaturization trend is presented in core component LED drive power as LED illumination, big in order to reduce manufacturing cost
Part LED drive power all cancels load open circuit protection circuit, and when lamp bead is opened a way, output voltage occurs 1.5 times or so
Rated output voltage, acutely heating, internal pressure increase are straight for internal meeting in the short time when output filter capacitor overvoltage excess load uses
To explosion-proof valve release, electrolyte can with gas from positioned at Y type explosion-proof valves central point erupt, easily splash to electrification in high voltage portion
Position, causes the potential safety hazard such as short-circuit, on fire.
At present, when designing circuit, it is contemplated that capacitor security risk that may be present, the wiring of generally use extension wire
Or increasing the type selecting surplus of rated capacitor voltage, the low cost of this design concept and LED drive power, the development of miniaturization become
Gesture phase Divergence.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the above, there is provided one kind is rational in infrastructure, manufacturing cost is low, improves
The aluminium electrolutic capacitor for preventing electrolyte splash of security performance.
The purpose of this utility model is achieved through the following technical solutions：A kind of alminium electrolytic condenser for preventing electrolyte splash
The pin drawn in device, including the body and body of capacitor, and bodies top in body, body upper part are cased with aluminum hull, this
Body is enclosed with plastic insulated pipe-casing, and bodies top is provided with Y type explosion-proof valves, and aluminum hull surface is coated with polyamide nylon dielectric film.
Further improvement of the utility model is：Aluminum hull is closely set with body upper part, and aluminum hull is overlapping with body upper part
Suit length is 3-5mm, and aluminum hull contacts the step of oriented inner side with bodies top, and aluminum hull is 2-5mm beyond the height of body.
Further improvement of the utility model is：Have steam vent at the top of aluminum hull, a diameter of 1mm of steam vent, steam vent away from
From aluminum hull top edge 1-4mm.
The utility model has advantages below compared with prior art：
The aluminum hull of the plating dielectric film with steam vent, plating dielectric film aluminum hull and bodies top contact site are cased with body upper part
The step that oriented inner side is shunk, the suit positioning of plated film aluminum hull when can facilitate the capacitor to produce.
In use, body caused by can preventing overvoltage of capacitor use or property abnormality itself is explosion-proof in electronic circuit
Electrolyte splash caused by valve release, improves the safety coefficient of LED drive power, while reduces the manufacturing cost of power supply, and just
In the realization of Miniaturization Design requirement.

Embodiment：
, below will be to the utility model to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Technical scheme in embodiment is clearly and completely described, it is clear that described embodiment is that the utility model part is real
Apply example, rather than whole embodiments.Element and feature described in a kind of embodiment of the present utility model can be with one
The element and feature shown in individual or more other embodiment is combined.It should be noted that for purposes of clarity, in explanation
Eliminate the expression and description of part unrelated with the utility model, known to persons of ordinary skill in the art and processing.It is based on
Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained on the premise of creative work is not paid
There is other embodiment, belong to the scope of the utility model protection.
As figures 1 and 2 show that a kind of a kind of the of aluminium electrolutic capacitor for preventing electrolyte splash of the utility model implements
The pin 2 drawn in mode, including the body 1 and body 1 of capacitor, and bodies top 3 in body 1, the top of body 1 are cased with
Aluminum hull 4, body 1 are enclosed with plastic insulated pipe-casing, and bodies top 3 is provided with Y type explosion-proof valves, and the surface of aluminum hull 4 is coated with polyamide nylon
Dielectric film.Aluminum hull 4 is closely set with the top of body 1, and the suit length d overlapping with the top of body 1 of aluminum hull 4 is 3-5mm, aluminum hull 4 with
The step 5 of the oriented inner side of the top contact of body 1, aluminum hull 4 are 2-5mm beyond the height h of body 1.Steam vent 6 is arranged at the top of aluminum hull 4,
6 a diameter of 1mm of steam vent, steam vent 6 is apart from the top edge 1-4mm of aluminum hull 4.
The utility model is mainly production and the suit technique of body and aluminum hull for increasing body, after the completion of body production
