Abstract
The utility model relates to a deformation-preventing capacitor belonging to the field of capacitor, which comprises a shell body, a capacitor core arranged in the shell body, a cover plate and wiring terminals arranged on the cover plate, and is characterized in that the cover plate is arranged above the capacitor core and is arranged in the shell body, a fixed ring is arranged on the cover plate, fixed teeth are arranged on the periphery of the fixed ring, the fixed teeth are abutted on the inwall of the shell body, and the distance between the cover plate and the top part of the shell body ranges from 0.5cm to 1cm. The deformation-preventing capacitor has the advantages of simple structure and reasonable design, the cover plate is arranged inside the shell body, and the fixed ring is welded on the cover plate, therefore, when the capacitor is being extruded, the fixed ring plays a role in extrusion resistance, and can ensure that the cover plate cannot deform due to extrusion.
Description
Technical field
The utility model relates to a kind of electronic component, is specifically related to a kind of anti-deformation capacitor, mainly is applicable to the capacitor technology field.
Background technology
Electric capacity is called in the common letter of capacitor, as its name suggests, is ' container of dress electricity ', is a kind of device that holds electric charge.Electric capacity is one of a large amount of electronic components that use in electronic equipment, is widely used in handing over every straight-through in circuit, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Capacitor generally by housing, be arranged on core body in housing, cover the cover plate on housing and the lead wire that arranges on the cover board forms, capacitor cover plate of the prior art is directly to cover on housing, then lead wire is set on housing, aforesaid way exists that structure is insecure, extruding is held yielding situation, the useful life that therefore can reduce capacitor.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, reasonable in design, do not allow yielding anti-deformation capacitor.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of anti-deformation capacitor, comprise housing, be arranged on capacitor body, cover plate and the setting binding post on the cover board of enclosure interior, it is characterized in that: described capacitor body is provided with cover plate, and described cover plate is arranged on enclosure interior, and described cover plate is provided with retainer plate.
The distance of described cover plate and case top is between 0.5cm-1cm.
Fixed teeth is set around described retainer plate.
Described retainer plate welding on the cover board.
Described retainer plate and cover plate are concentric circles.
Described retainer plate is steel material, and hardness is strong, and compressive property is good.
Described fixed teeth is supported and is combined on the inwall of housing.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, cover plate is arranged on enclosure interior, then on the cover board is welded and fixed circle, when capacitor is squeezed, retainer plate has played anti-extrusion effect, can guarantee that cover plate can not be out of shape because of extruding.
