Abstract
The utility model relates to a kind of electrolytic capacitor with anti-antistructure, including ontology, anode and cathode, the installation dimension of the anode is greater than the installation dimension of cathode or the installation dimension of cathode is greater than the installation dimension of anode.The electrolytic capacitor has been specifically designed anti-antistructure, the difference of anode and cathode is interface differentiation physically, solve the problems, such as that electrolytic capacitor is anti-loaded from structural point, because after anti-loaded, since positive and negative anodes installation dimension is different, correct wiring assembly can not be carried out, to avoid anti-loaded problem completely, it just easily finds the problem early stage production process, avoids problem further expansion, cause the loss that can not be retrieved.The electrolytic capacitor is suitable for DC environment, such as the dc-link capacitance of field of power electronics, can also be used as energy storage device in energy storage field.
Description
Technical field
The utility model relates to technical field of electronic components more particularly to a kind of electrolytic capacitors with anti-antistructure.
Background technique
Electrolytic capacitor itself has polarity, including anode and cathode, must install in strict accordance with polarity when installing connection,
Cannot be anti-loaded, it can expand rapidly, damage after otherwise powering on, or even explosion, so existing electrolytic capacitor, has apparent
Positive and negative anodes mark, as depicted in figs. 1 and 2, electrolytic capacitor include ontology 1, anode 2, cathode 3 and shell 4, the white on shell 4
Part is exactly cathode color characteristic 42, and white portion is generally gone back emblem equipped with cathode symbol 41, is explicitly indicated.Color management
Although method effectively, can not be fully solved anti-loaded this problem, because of 3 knot of the anode 2 of existing electrolytic capacitor and cathode
Structure be it is the same, putting back can also install, be not easy to check after anti-loaded and, especially modern power electronics devices, stack bus bar
In can use many electrolytic capacitors as bus capacitor, if be only distinguish by color of shell, it is easy to wrongly installed.Once dress
Mistake, and do not check and, explosion or damage occur after only powering on could find that have resulted in destruction at this time, loss is difficult to
It retrieves.
Utility model content
The purpose of this utility model is to provide a kind of electrolytic capacitors with anti-antistructure.
Technical solution provided by the utility model are as follows: a kind of electrolytic capacitor with anti-antistructure, including ontology, anode and
Cathode, which is characterized in that the installation dimension of the anode is greater than the installation dimension of cathode or the installation dimension of cathode is greater than just
The installation dimension of pole.
Wherein, the anode is positive terminal, and the cathode is negative terminal.
Wherein, the positive terminal is equipped with screw hole, and the negative terminal is equipped with screw hole, described two screw hole rulers
Very little difference.
Wherein, the positive terminal is equipped with pin, and the negative terminal is equipped with pin, described two pin rulers
Very little difference.
Wherein, the cross-sectional area ratio of the anode and cathode is 1:1.5~3 or 1.5~3:1.
Wherein, the ontology is equipped with shell, and the shell is equipped with cathode symbol and cathode color characteristic.
The utility model has the following beneficial effects: the electrolytic capacitor has been specifically designed anti-antistructure, i.e. positive installation ruler
The very little installation dimension for being greater than anode greater than the installation dimension of cathode or the installation dimension of cathode, the difference of anode and cathode are
Interface differentiation physically solves the problems, such as that electrolytic capacitor is anti-loaded from structural point, because after anti-loaded, since positive and negative anodes are pacified
It is different to fill size, correct wiring assembly can not be carried out, to avoid anti-loaded problem completely, early stage production process just very
Problem is easily found out, problem further expansion is avoided, causes the loss that can not be retrieved.The electrolytic capacitor is suitable for direct current
Environment can also be used as energy storage device in energy storage field such as the dc-link capacitance of field of power electronics.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As the embodiment one of the electrolytic capacitor described in the utility model with anti-antistructure, as shown in Figures 3 to 5, packet
Ontology 1, anode and cathode are included, the installation dimension of the cathode is greater than the installation dimension of anode.The electrolytic capacitor is suitable for straight
Environment is flowed, the dc-link capacitance of field of power electronics is used as in the present embodiment.
In the present embodiment, the anode is positive terminal 21, and the cathode is negative terminal 31, and the anode connects
Terminal 21 is equipped with screw hole 22, and the negative terminal 31 is equipped with screw hole 32, using screw hole mount scheme, described two screw holes
22,32 sizes are different, and specifically, the diameter of screw hole 32 is greater than the diameter of screw hole 22.
The electrolytic capacitor has been specifically designed anti-antistructure, i.e. the installation dimension of cathode is greater than positive installation dimension, just
The difference of pole and cathode is interface differentiation physically, solves the problems, such as that electrolytic capacitor is anti-loaded from structural point, because of dress
After anti-, since positive and negative anodes installation dimension is different, correct wiring assembly can not be carried out, so that anti-loaded problem is avoided completely,
The early stage of production process just easily finds the problem, and avoids problem further expansion, causes the loss that can not be retrieved.
In the present embodiment, the installation dimension of the anode is greater than the installation dimension of cathode and feasible.It is described
The preferred value of the cross-sectional area ratio of anode and cathode is 1:1.5~3 or 1.5~3:1.Anode and cathode cross section ruler
Very little gap is too small, and the possibility of wrong assembly, gap is too big, and will affect assembly efficiency, also will affect beauty.
