Paster aluminium electrolyte electric capacity is one of modal electric capacity on board of today, rises in electronic industry Vital effect, along with electronic product is to slim, miniaturization, electronic circuit is to multi-layer sheet Development, electronic devices and components are the most rapidly to miniaturization, surface mount manner fast development, therefore components and parts bag Include aluminium electrolutic capacitor and will progressively move towards Surface Mounting Technology and high efficiency.

At present, at SMD aluminium electrolutic capacitor, or even whole SMD components and parts circle are in use Will run into working environment scope wide, the temperature difference is big, and efficiency is low, and the problem of the easy aspect such as sealing-off, For satisfied society development in science and technology needs, simultaneously as a qualified SMD aluminium electrolutic capacitor, this The solution of a little problems is extremely urgent.

Utility model content

The purpose of this utility model is that provides a kind of efficient SMD aluminum electricity to solve the problems referred to above Electrolysis condenser.

This utility model is achieved through the following technical solutions above-mentioned purpose: a kind of efficient SMD aluminium electroloysis Capacitor, including base, capacitor cylinder, paster pin, thermal insulation layer, aluminium foil and electrolysis paper roll and dissipate Heat channel；It is characterized in that: described capacitor cylinder is arranged on base, and base has radiating groove, described Pin is drawn by capacitor cylinder, walks around base bottom and is stuck on base, in capacitor column body Having aluminium foil to become close tubular structure with electrolysis paper roll Stagger-wrap, outermost has one layer of thermal insulation layer.

Further, for reaching to extend the service life of this capacitor, described base and capacitor cylinder Between have little gap for air circulation heat radiation, and derive hot-air by radiating groove.

Further, for reaching the purpose that this capacitor can use in high temperature, described thermal insulation layer is asbestos Mix heat insulation material, contacting of electrolyte and capacitor column body case can be isolated simultaneously.

Further, the purpose little for reaching efficient volume, the aluminium foil of described aluminium foil and electrolysis paper roll passes through Electrochemical corrosion is also processed, and cincture tight with electrolytic paper, more moistening also around, electrolytic paper through extrusion ring Soak in the electrolytic solution.

Further, for reaching to save welding material, the most effectively promote the purpose of weld strength, described Pin is three-dimensional ramp shaped structure, separates downwards bipod along the gradient, and bipod all raises up, cross section in Triangular shape.

The beneficial effects of the utility model are: the beneficial effects of the utility model are: this capacitor is the most steady Fixed, strong adaptability, unique thermal insulation layer design, make the working environment of this capacitor have the biggest extension, Coordinating bottom heat radiation groove, be obviously improved service life, aluminium foil can increase seven times larger through electrochemical corrosion Surface area, makes capacitor efficiency significantly improve, unique three-dimensional pin design, can be with less welding material Material reaches more firm welding effect；This utility model is handsome in appearance simultaneously, easy to use, cheap, Can meet most electric capacity installation requirements on market, during work, stability is strong, is suitable for promoting the use of.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this The scope of utility model protection.

2. referring to Fig. 1-2, a kind of efficient SMD aluminium electrolutic capacitor, including base 1, capacitor Cylinder 2, paster pin 3, thermal insulation layer 4, aluminium foil and electrolysis paper roll 5 and radiating groove 6；It is characterized in that: Described capacitor cylinder 2 is arranged on base 1, and base 1 has radiating groove 6, and described pin 3 is by electric capacity Device cylinder 2 is drawn, walks around bottom base 1 and be stuck on base 1, have inside capacitor cylinder 2 Aluminium foil becomes close tubular structure with electrolysis paper roll 5 Stagger-wrap, and outermost has one layer of thermal insulation layer 4.

As a kind of technical optimization scheme of the present utility model: described base 1 and capacitor cylinder 2 it Between have little gap for air circulation heat radiation, and derive hot-air by radiating groove 6；Described thermal insulation layer 4 Mix heat insulation material for asbestos, contacting of electrolyte and capacitor cylinder 2 shell can be isolated simultaneously；Institute The aluminium foil stating aluminium foil and electrolysis paper roll 5 through electrochemical corrosion and is processed, and cincture tight with electrolytic paper, Again through extrusion ring around, electrolytic paper moistens and soaks in the electrolytic solution；Described pin 3 is three-dimensional ramp shaped structure, Separating downwards bipod along the gradient, and bipod all raises up, cross section is triangular shape.

This utility model is in use, it then follows during circuit design, according to size of current and the alternating current of load Operating frequency choose suitable electric capacity, rather than according to the voltage of load and power；Should first measure load electricity The exact value of stream, selects the capacity of decompression capacitor then referring to example；For ensureing the reliable work of capacitor Making, selection that it is pressure should be greater than the supply voltage of twice；The selection of bleeder resistance must assure that and requiring Release in time the electric charge on power down container；This electric capacity is SMD aluminium electrolutic capacitor, should spy during welding Zhu Yi electric cautery ground connection；Additionally this utility model is electronic device, it should be noted that Electrical Safety.
