Abstract
The utility model discloses a high-temperature edge-thickened metallized thin film for a capacitor core body, the thin film comprises a polypropylene thin film, a metal plated layer is arranged on the polypropylene thin film, and the metal plated layer on the edge of the polypropylene thin film is provided with a bulge. The high-temperature edge-thickened metallized thin film has simple structure, and the edge adopting the thin film is increased to an edge-thickened structure from the ordinary structure, thereby reducing the contact resistance of the end surface, realizing small loss, achieving small temperature increase and high reliability, and improving the anti-pulse impact performance of a product.
Description
Technical field:
The utility model relates generally to a kind of metallization, relates in particular to the thickened metalized film in a kind of capacitor core body and function high temperature edge.
Technical background:
Film capacitor is a kind of of capacitor, has advantages such as loss is little, insulation resistance is high, frequency characteristic is good, reliability is high, good temp characteristic, has comparatively widely to use; The current thin film capacitor can be divided into two kinds of metal forming formula and metallization formulas from the electrode form, the advantage that the metallic film capacitor volume is little, capacity big, self-healing feature is arranged, overvoltage capabilities is high, along with the complete electronic set continuous shortening in update cycle, and raising compact and that digitlization requires, become the main flow of film capacitor, thereby metallized film is the main raw material(s) of making film capacitor, and the characteristic of capacitor is had a direct impact.
The capacitor of metallized film all can decompose generation gas after losing efficacy, because the rising of temperature, brought very big loss, reliability of products can be poor, and anti-pulse shock ability is particularly in the electronic arc-control device resonant circuit, because the line design length and the complexity of electronic product, cause disturbing and clutter, cause electronic circuit reliability energy and Electro Magnetic Compatibility poor, limited the widespread usage of general capacitor.
The utility model content:
The purpose of this utility model is in order to remedy the deficiency of defectiveness, provide a kind of capacitor core body and function high temperature edge thickened metalized film, film edge increases to the edge structure thicker by ordinary construction, thereby reduce the contact resistance of end face, loss is little, thereby it is little to reach temperature rise, reliability height, the anti-pulse shock performance of raising product.
The utility model is achieved through the following technical solutions:
The thickened metalized film in a kind of capacitor core body and function high temperature edge, it is characterized in that: described film includes polypropylene film, is coated with metal layer on the described polypropylene film, and the metal layer at described polypropylene film edge is provided with projection.
The thickened metalized film in described capacitor core body and function high temperature edge, it is characterized in that: described metal layer is that spray does not have lead-coat on the metal spraying silk.
The capacitor core body adopts the thickened metalized winding film in high temperature edge, and temperature is promoted to 105 ℃ by original 85 ℃, thereby greatly reduces the loss that is brought by temperature rise, increases reliability of products; Film edge increases to the edge structure thicker by ordinary construction, and square resistance is: general area 6-9 Ω/cm
2, thickened area 2-4 Ω/cm
2Thereby reduce the contact resistance of end face, loss is little, thereby it is little to reach temperature rise, the reliability height, improve the anti-pulse shock performance of product, adopt high vacuum solid epoxy PBT plastic casing dosing technology behind the thickened metalized polypropylene film in capacitor core body coiling high temperature edge, improve electric capacity in grade of following life-span of peer-level, and shell adopts high temperature flame-proof PBT material, heatproof reaches 120 ℃, stops capacitor and change the hot operation state lower casing metaboly that causes because of air pressure inside under the condition of high temperature.
The utility model has the advantages that:
The utility model is simple in structure, adopts film edge to increase to the edge structure thicker by ordinary construction, thereby reduces the contact resistance of end face, and loss is little, thereby it is little to reach temperature rise, reliability height, the anti-pulse shock performance of raising product.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
The thickened metalized film in a kind of capacitor core body and function high temperature edge includes polypropylene film 1, and polypropylene film 1 is provided with the coat of metal 2, and the coat of metal 2 at polypropylene film 1 edge is provided with projection 3.
Application example:
The electric capacity that RC assembly electronic arc-control device uses core body to be wound with the thickened metalized polypropylene film in the high temperature edge integrated design composition resonant circuit of connecting with resistance; whole epoxy resin and the flame-retardant PBT of adopting in series connection back moulded the shell encapsulation; effective filtering interfering and absorb clutter; good anti-pulse ability (protective circuit); and reduce the line design length and the complexity of electronic product; improve electronic circuit reliability energy and Electro Magnetic Compatibility; be applicable to that hot-tempered circuit falls in the power supply cross-line; thyristor; the demagnetization arc extinguishing of relay, domestic electric appliances controller and Digit Control Machine Tool; electric control cabinet; sound equipment such as establishes at the alternating current-direct current occasion.
