In view of the shortcomings of the prior art, the invention provides a kind of multifunctional combination thin film capacitor, existing skill is overcome The deficiency of art, reasonable in design, compact conformation is welded using the parallel connection of multiple core bags, and capacity is twice of single bag, so that holding Amount is bigger, while overall volume reduces, is easily installed maintenance, while multiple core bags are in a housing, is easy to fill shell encapsulating, pole Production efficiency is improved greatly, cost is reduced.
(2) technical scheme
To realize object above, the present invention is achieved by the following technical programs:
A kind of multifunctional combination thin film capacitor, including housing, and the core bag being arranged in the housing, the housing It is interior to be provided with multiple core bags, wherein the positive pole leading-out terminal and negative pole leading-out terminal of each core bag electrical connection, casing center Position is provided with main core bag, core bag supplemented by other.
Multiple auxiliary cores, which surround to take all of around main core, to be uniformly distributed in week.
The core bag is odd number 3 or 5 or 7.
Connection sheet is equipped with the core bag positive and negative electrode leading-out terminal, the connection sheet is provided with fixing bolt, the company The contact pin other end is provided with connects bayonet socket.
The connection sheet is provided with stretching structure.
The connection sheet is copper sheet.
The hull outside face is provided with arc surface.
(3) beneficial effect
The embodiments of the invention provide a kind of multifunctional combination thin film capacitor.Possesses following beneficial effect:The present invention is adopted Welded, capacity is twice of single bag, so that capacity is bigger, while overall volume reduces, be easy to the parallel connection of multiple core bags Install and safeguard, while multiple core bags are in a housing, are easy to fill shell encapsulating, greatly improve production efficiency, reduce cost.
