Description

A kind of rectangular aluminium electrolutic capacitor
Technical field
The present invention relates to electronic field more particularly to a kind of rectangular aluminium electrolutic capacitors.
Background technique
Large-scale aluminum electrolysis capacitor has generally comprised core packet, shell, cover board and extraction electrode.Wherein, core packet includes Kernel, kernel are formed by positive and negative electrode electrolytic aluminum foil, electrolyte and electrolytic paper winding.Kernel occupies entire large-scale aluminium electrolysis Most of volume of capacitor product, and its weight is also part most heavy in entire large-scale aluminum electrolysis capacitor.Its volume is big, Weight is big, becomes a very big problem so being fixed and being encapsulated in entire large-scale aluminum electrolysis capacitor.Currently, in large size It is typically all that fixation is encapsulated using gel or pitch in aluminium electrolutic capacitor.However, being sealed using gel or pitch Dress is fixed so that the combustible organic deal of large-scale aluminum electrolysis capacitor increases, and increases the risk of aluminium electrolutic capacitor;In addition, It is easy to cause the weight of aluminium electrolutic capacitor to increase using gel or pitch, and the volume of aluminium electrolutic capacitor is increased. Also, the bad control of the loading of gel or pitch, and it is both high temperature melting filling, there is certain risk.And It is also easy to cause large-scale aluminum electrolysis capacitor thermal coefficient low using gel or pitch, so that large-scale aluminum electrolysis capacitor is interior Core thermal diffusivity is bad, and then influences the service life of large-scale aluminum electrolysis capacitor.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of good heat dissipation, it is easy to operate simultaneously And the rectangular aluminium electrolutic capacitor that sealing effect is good.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows:, a kind of rectangular aluminium electrolutic capacitor, including Core packet and shell, the shell are accommodated core packet by sealing connecting component, and sealing connecting component includes that two cross sections are in work Connector, stainless steel plate, rubber ring, positive wire and the negative wire of font;The positive strap of the core packet and cathode connect Contact pin passes through connector respectively and connect with positive wire and negative wire, and the connector is fixedly connected on stainless by rubber ring On steel plate, it is tightly connected between stainless steel plate and shell.
Above-mentioned rectangular aluminium electrolutic capacitor, it is preferred that the cross section of the rubber ring is in I-shaped, and is arranged even In the annular groove of fitting, the connection through-hole connecting with rubber ring is provided on the stainless steel plate, the stainless steel plate is by squeezing Rubber ring and connector is pressed to be tightly connected.
Above-mentioned rectangular aluminium electrolutic capacitor, it is preferred that the thickness of the stainless steel plate is between 3mm-6mm.
Above-mentioned rectangular aluminium electrolutic capacitor, it is preferred that the connector making of pure aluminum.
Above-mentioned rectangular aluminium electrolutic capacitor, it is preferred that the positive wire and negative wire are by way of butt-joint It is connected on connector.
Above-mentioned rectangular aluminium electrolutic capacitor, it is preferred that be provided on the connector and positive strap or cathode company The connection ring of contact pin connection.
Above-mentioned rectangular aluminium electrolutic capacitor, it is preferred that the stainless steel plate passes through the connection type being fully welded and shell is close Envelope connection.
Compared with the prior art, the advantages of the present invention are as follows: pass through stainless steel plate in the present invention for core encapsulation in shell It is interior, good heat dissipation effect, and it is easy to operate.Positive strap and negative straps are connected by connection ring and connector in the present invention It connects, positive wire and negative wire are connect by butt-joint with connector;Each tie point is stable so that square aluminum electricity of the present invention The stability of electrolysis condenser enhances.Stainless steel plate is tightly connected by squeezing rubber ring and connector in the present invention, and structure is simple And sealing effect is good.
