Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a capacitor module for a metallized film of an external defibrillator. Background Art

[0002] The pulse capacitors used in automatic external defibrillators (abbreviated as AEDs abroad) mainly adopt circular oil-filled packages with 250 or 187 double / single insert tabs for lead-out; or oval metal packages / tinplate oil-filled packages with bolts / nuts for lead-out. In China, circular plastic packages with insulating silicone wires and flag-shaped terminal insert tabs are mainly used for lead-out.

[0003] Traditional thin-film capacitors for pulse power in defibrillators are large in volume, occupy a lot of space, cannot be closely matched between components, are easily affected by each other, and reduce the space utilization rate. Summary of the Invention

[0004] In order to solve the problems of the existing capacitors occupying a lot of space and having low space utilization rate, the utility model provides a capacitor module for a metallized film of an external defibrillator, which can miniaturize and modularize the product and effectively improve the space utilization rate.

[0005] The technical solution is as follows: a capacitor module for a metallized film of an external defibrillator, which includes a housing and a capacitor core. The cross-section of the housing is flat. A groove is provided on the outer wall of the bottom of the housing, and a bottom lead-out wire through-hole is opened at the bottom of the groove. An upper lead-out wire through-hole is opened at the top of the side wall of the housing. The capacitor core is located inside the housing, and the lead-out wires at both ends respectively pass through the bottom lead-out wire through-hole and the upper lead-out wire through-hole. The top opening of the housing is a sealing surface.

[0006] Further, the sealing surface is sealed with a cover plate or directly sealed with epoxy resin.

[0007] After adopting the utility model, the housing of the capacitor is flat, the capacitor core is installed inside the housing, and the lead wires extend out from the bottom lead-out wire through-hole and the upper lead-out wire through-hole respectively, without exceeding the housing, which does not affect the installation of other components, miniaturizes and modularizes the product, and effectively improves the space utilization rate. Brief Description of the Drawings

[0008] Figure 1 is a schematic external structure diagram of the utility model;

[0009] Figure 2 is a schematic internal structure diagram of the utility model. Detailed Description

[0010] See Figure 1 , Figure 2As shown, a capacitor module for an external defibrillator metallized film includes a housing 1 and a capacitor core 2. The illustrated capacitor is in an upside-down state, that is, the upper part in the figure is the bottom of the capacitor, and the lower part is the top of the capacitor. The cross-section of the housing 1 is flat, similar to an ellipse, but the two side walls of the housing 1 are flat, which is convenient for installation. Three grooves 3 are provided on the outer wall of the bottom of the housing 1, and bottom lead-through holes 4 are respectively opened at the bottoms of the three grooves. An upper lead-through hole 5 is opened at the top of one of the side walls of the housing 1. The capacitor core 2 is located inside the housing 1, and the lead-out wires 7 at both ends respectively pass through the bottom lead-through holes 4 and the upper lead-through hole 5. The opening at the top of the housing 1 is a sealing surface 6, and the sealing surface 6 is sealed with a cover plate and filled with potting compound inside, or directly sealed with epoxy resin.

[0011] In the structure of this application, the housing 1 can be made of a plastic housing, fully considering the miniaturization and modular requirements of medical defibrillators, reducing the installation space and not affecting the installation of other devices. The capacitor core 2 can adopt a shape that closely adheres to the inner wall of the housing 1, and fits tightly after being installed. The gaps on both sides can be filled with potting compound.
