Description
Technical field
The utility model relates to a kind of metallized polypropylene film capacitor of alternating current machine, belong to technical field of electronic equipment.
Background technique
Metallized film capacitor is to replace metal foil as electrode in the surface of polyester film vapor deposition layer of metal film, because
For layer of metallized film thickness be much smaller than metal foil thickness, therefore wind after volume also it is more small in size than type metal foil type capacitor very
It is more.The great advantage of metalized film capacitor is " self-healing " characteristic.If so-called self-healing feature is exactly thin film dielectrics due in certain point
Existing defects and there is puncture short under overvoltage effect, and the metalization layer of breakdown point can be molten in moment under arcing
Change evaporation and formed very little without metal area, make two pole pieces of capacitor again mutually insulated and remain to work on, because
This greatly improves the reliability of capacitor work.The lead of existing metallic film capacitor is too thin, be easy to happen it is unexpected and
Caused by damage, and between lead and gilding layer welding form resistance, energy loss can be caused.
Summary of the invention
(1) technical problems to be solved
A kind of in order to solve the above problems, the utility model proposes metallized polypropylene film capacitor of alternating current machine.
(2) technical solution
The metallized polypropylene film capacitor of alternating current machine of the utility model comprising shell, lead, polypropylene screen, gold
Belong to coating, connection sheet and installation foot；It is provided with lead in the shell, is provided with installation foot on shell；The installation foot includes
Collets and metal block；The metal block is arranged in collets two sides；Connection sheet is provided on the lead, lead passes through poly- third
Alkene film and the coat of metal, lead are connect with metal block；The polypropylene screen and the arrangement of coat of metal coiling；On the coat of metal
It is provided with card seam；The connection sheet is connect with the coat of metal.
As preferential technical solution, the lead and connection sheet are integrally formed.
As preferential technical solution, installation screw thread is provided on the collets and metal block.
(3) beneficial effect
Compared with the prior art, the utility model has the following beneficial effects: the utility model metallized polypropylene
Film capacitor of alternating current machine structure is simple, and lead is directly connected to the coat of metal, avoids between lead and gilding layer because of welding
And the bridge resistance formed, traditional pin is substituted with installation foot, installation convenience, avoid pin it is too thin and caused by damage.

It is equipped with connection sheet 5, lead 2 passes through polypropylene screen 3 and the coat of metal 4, and lead 2 is connect with metal block 62；3 He of polypropylene screen
The arrangement of 4 coiling of the coat of metal；Card seam 41 is provided on the coat of metal 4；The connection sheet 5 is connect with the coat of metal 4.
Wherein, the lead 2 and connection sheet 5 are integrally formed；Installation spiral shell is provided on the collets 61 and metal block 62
Line.
A kind of metallized polypropylene film capacitor of alternating current machine of the utility model has below beneficial to fruit: this is practical new
Type metallized polypropylene film capacitor of alternating current machine structure is simple, and lead is directly connected to the coat of metal, avoids lead and spray
The bridge resistance formed between layer gold by welding substitutes traditional pin with installation foot, installation convenience, avoid pin it is too thin and
Caused by damage.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality
With novel claimed technology contents, it is all described in the claims.
