Abstract
The utility model discloses a low-impedance lead type aluminum electrolytic capacitor for an LED, which comprises an aluminum shell and a rubber plug which are connected with each other in a sealed manner. A core covering is arranged in the aluminum shell and includes a foil guiding strip, wherein the foil guiding strip is provided with an aluminum guide pin body connected with electrodes on the rubber plug through copper leads. The low-impedance lead type aluminum electrolytic capacitor for the LED has the advantages that the impedance of the aluminum electrolytic capacitor is reduced by the aluminum guide pin body arranged inside the aluminum electrolytic capacitor and the guide pin copper leads exposed outside the aluminum electrolytic capacitor, and self-heating of the aluminum electrolytic capacitor is decreased, so that the performance of the aluminum electrolytic capacitor is improved and the service life of the aluminum electrolytic capacitor is prolonged.
Description
Technical field
The utility model relates to a kind of alminium electrolytic condenser, relates in particular to the Low ESR wire type alminium electrolytic condenser of a kind of LED of being used for.
Background technology
At present, in the led light source industry, for whether using alminium electrolytic condenser to have dispute in the circuit.The key that causes dispute is the life-span and the integrity problem of alminium electrolytic condenser.Because high-quality led light source requires the very long life-span, and the life-span of alminium electrolytic condenser often becomes the bottleneck in restriction official's LED life-span, because the narrow and small compactness in space of living in is difficult to heat radiation, so the operating ambient temperature of alminium electrolytic condenser is very high, and alminium electrolytic condenser is at high temperature worked and bear the high frequency large ripple current, so can produce bigger self-heating phenomenon simultaneously, and dry gradually and inefficacy with the prolongation alminium electrolytic condenser of operating time.If will reduce the antijamming capability of power supply to power network fluctuation but remove electrochemical capacitor simply, also can bring the risk that lost efficacy because of thunderbolt, simultaneously, the high frequency large ripple current that no electrolytic capacitor brings and the low frequency flicker that causes begin more and more to be noted by the people, even if it is subtle to be lower than the stroboscopic naked eyes of 165Hz, but caused physiological discomfort, the low-frequency ripple that amplitude is big can also can be caused some digital camera equipment the bright dark grid of difference frequency flicker to occur.Therefore be necessary to improve existing wire type alminium electrolytic condenser, reduce alminium electrolytic condenser self-heating at high temperature, improve the life-span and the reliability of alminium electrolytic condenser product.
Summary of the invention
Technical problem to be solved in the utility model provides the Low ESR wire type alminium electrolytic condenser of a kind of LED of being used for, reduces alminium electrolytic condenser self-heating at high temperature, improves the life-span and the reliability of alminium electrolytic condenser product.
The utility model is to solve the problems of the technologies described above the Low ESR wire type alminium electrolytic condenser that the technical scheme that adopts provides a kind of LED of being used for, comprise aluminum hull and plug that sealing links to each other, be provided with the core bag in the described aluminum hull, described core bag comprises leads chaff, wherein, the described chaff of leading is provided with aluminium guide pin body, and described aluminium guide pin body links to each other with electrode on the plug by copper lead-in wire.
The above-mentioned Low ESR wire type alminium electrolytic condenser that is used for LED, wherein, described copper wire surface is zinc-plated.
The above-mentioned Low ESR wire type alminium electrolytic condenser that is used for LED, wherein, described copper wire length 6～8mm.
The utility model contrast prior art has following beneficial effect: the Low ESR wire type alminium electrolytic condenser that is used for LED that the utility model provides, the aluminium guide pin body that is in alminium electrolytic condenser inside by setting goes between with the guide pin copper that is exposed at the alminium electrolytic condenser outside and reduces the impedance of alminium electrolytic condenser, reduce the alminium electrolytic condenser self-heating, thereby improve the performance and the life-span of product.
Description of drawings
Fig. 1 is the utility model aluminium electrolytic capacitor structural representation.
Among the figure:
1 positive guide pin copper, 2 negative guide pin copper, the 3 aluminium guide pin bodies that go between that go between
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the utility model aluminium electrolytic capacitor structural representation.
See also Fig. 1, the Low ESR wire type alminium electrolytic condenser that is used for LED that the utility model provides, comprise aluminum hull and plug that sealing links to each other, be provided with the core bag in the described aluminum hull, described core bag comprises leads chaff, wherein, the described chaff of leading is provided with aluminium guide pin body 3, and described aluminium guide pin body links to each other with electrode on the plug by copper lead-in wire.
The material that the guide pin that the utility model provides is in the aluminium guide pin body 3 of alminium electrolytic condenser inside is the aluminium of purity more than 99.94%, the positive guide pin copper lead-in wire 1 and 2 in the negative guide pin copper lead-in wire that are exposed at the alminium electrolytic condenser outside use copper alloy, its material is that to contain the beryllium amount be 2%～4% copper alloy, and guide pin copper wire surface is zinc-plated to improve solderability.And traditional guide pin lead-in wire material is the core, copper tinning.
Because the conductance of copper is better than iron, produce alminium electrolytic condenser so adopt above-mentioned copper guide pin, compare with the alminium electrolytic condenser of traditional guide pin production, promoting to some extent aspect impedance behavior and the life performance: the impedance of product reduces about 5%, its temperature rise of ripple current that applies 1 times reduces about 1 ℃, its temperature rise of rated ripple current that applies 2 times reduces about 3 ℃, and the average life span of product prolongs about 5% in the load test of 125 DEG C high temperature in addition.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
