Description

Novel low-self-inductance electronic capacitor

The technical field is as follows:

the utility model relates to an electronic capacitor technical field especially relates to a novel electronic capacitor of low self-inductance.

Background art:

in the technical field of power electronic capacitors, the internal core of the capacitor generally adopts an interconnection mode (as shown in fig. 2) with opposite metal spraying surfaces, and the structure has the problems of complex connection method of the internal core, long path of a connection circuit and complex insulation treatment process, so that the capacitor has the characteristics of large self-inductance, high ESR (equivalent series resistance) and large loss tangent on electrical parameters, and the temperature of the capacitor is increased, the voltage resistance is reduced and the reliability and the service life are seriously influenced in practical application.

The utility model has the following contents:

an object of the utility model is to provide a novel electronic capacitor of low self-inductance.

The content of the utility model is as follows: the utility model provides a novel electronic capacitor of low self-inductance, its shell that includes vertical setting, the level is provided with a plurality of core, a plurality of in the shell the core is from supreme alignment in proper order down arranging, the both ends of core all are provided with spouts the gold layer, and are adjacent the homonymy of core spouts the gold layer and passes through connecting electrode interconnect, the top the core spout the gold layer and be connected with binding post.

Further, the housing is square.

The utility model has the advantages that: the utility model has simple structure, adopts a brand new core arrangement mode, changes the commonly adopted core interconnection mode with relative metal spraying surfaces into the connection mode with the same side metal spraying surfaces, greatly shortens the length of the connection electrode inside the capacitor, and further reduces the self-inductance and ERS value of the capacitor; meanwhile, the square shell can facilitate the combined installation of a plurality of capacitors, and the current carrying capacity of the capacitors is effectively improved.

Description of the drawings:

fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic structural view of a nitrogen-blowing ring of the present invention;

in the figure, a shell 1, a core 2, a gold-sprayed layer 3, a connecting electrode 4 and a connecting terminal 5.

The specific implementation mode is as follows:

as shown in fig. 1 and 2, a novel low self-inductance electronic capacitor comprises a vertically arranged housing 1, a plurality of cores 2 are horizontally arranged in the housing 1, the plurality of cores 2 are sequentially aligned from bottom to top, gold-sprayed layers 3 are respectively arranged at two ends of each core 2, the same-side gold-sprayed layers 3 of the adjacent cores 3 are connected with each other through a connecting electrode 4, and the gold-sprayed layer 3 of the core 3 at the top end is connected with a connecting terminal 5; the shell 1 is square; the utility model has simple structure, adopts a brand new core arrangement mode, changes the commonly adopted core interconnection mode with relative metal spraying surfaces into the connection mode with the same side metal spraying surfaces, greatly shortens the length of the connection electrode inside the capacitor, and further reduces the self-inductance and ERS value of the capacitor; meanwhile, the square shell can facilitate the combined installation of a plurality of capacitors, and the current carrying capacity of the capacitors is effectively improved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
