Abstract

The utility model discloses a capacitor shell which comprises a shell body, wherein a central boss is arranged on the top of the shell body; an opening on the top of the shell body is positioned on the central boss; tooth grooves are formed on the edge of the opening of the shell body; the edge wall of a cover body of an end cover extends to form an extension edge; sawteeth are formed on the bottom surface of the cover body of the end cover; the end cover is covered on the shell body; the sawteeth on the bottom surface of the cover body of the end cover are meshed into the tooth grooves on the central boss of the shell body; and the extension edge of the cover body of the end cover is sleeved outside the central boss on the top of the shell body. The capacitor shell is easy to implement and convenient to use; and the assembly precision of the capacitor shell is improved.

Description

A kind of capacitor case

Technical field

The utility model relates to the capacitor production field, is specially a kind of capacitor case.

Background technology

Capacitor is a kind of device that holds electric charge, and it is widely used in the electron electric power equipment, and circuit is played at a distance from effects such as straight-through friendship, bypass, filtering, resonant tank, power conversion.Constitute by capacitor case and the pole plate etc. that places capacitor case on the capacitor arrangement, during the assembling of prior art capacitor case, be prone to the phenomenon of dislocation between end cap and the housing, influence the assembly precision of capacitor case.

The utility model content

The utility model purpose provides a kind of capacitor case, to solve the problem of prior art capacitor case housing and end cap error-prone.

In order to achieve the above object, the technical scheme that the utility model adopted is:

A kind of capacitor case includes the housing of open top, and said case top is covered with end cap; On the said end cap electrode terminal is installed, it is characterized in that: said case top has central boss, and the uncovered of case top is positioned on the central boss; And the central boss end face at the uncovered edge of housing forms a plurality of teeth groove; The limit wall of said end cap lid is extended for extension edge, and end cap lid bottom surface forms a plurality of sawtooth that cooperate one by one with housing central boss teeth groove, and said end cap covers on housing; The sawtooth of end cap lid bottom surface snaps in the housing central boss teeth groove one by one, and the extension edge of end cap lid is enclosed within outside the case top central boss.

Described a kind of capacitor case is characterized in that: the extension edge of said end cap lid connects as one through screw and housing central boss.

The utility model is easy to realize, and is easy to use.Housing central boss end face around uncovered forms teeth groove; The sawtooth of end cap lid bottom surface moulding snaps in the teeth groove of housing central boss; Through the cooperate accurate location of realizing end cap and housing of sawtooth with teeth groove; The extension edge of end cap limit wall is enclosed within outside the central boss, and through screw end cap is fixed on case top.In the utility model capacitor case and end cap when assembling mistake easily not, therefore improved the assembly precision of capacitor case.
