Description
Technical field
The utility model relates to capacitor technology field, particularly relates to a kind of power capacitor aluminium lid.
Background technology
Capacitor, being usually called for short its ability holding electric charge is electric capacity, represents by letter C.Definition 1: capacitor, as the term suggests being ' container of dress electricity ', is a kind of device holding electric charge.English name: capacitor.Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Definition 2: capacitor, any two insulated from each other and all form a capacitor between the conductor (comprising wire) of being separated by very near.
Electric capacity is different from capacitor.Electric capacity is fundamental physical quantity, symbol C, and unit is F (farad).
The special formula of general formula C=Q/U plane-parallel capacitor: electric field strength E=U/d between plate, condenser capacitance determines formula C=ε S/4 π kd.
Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.And having driven the development of associated materials, equipment Industry, China has become global capacitor big producing country.
Power capacitor of the prior art is all generally the container cavity being combined to form a sealing by cylindrical metal shell and aluminium lid, the important spare part of capacitor is installed in container cavity, but in real production process, metal shell and aluminium lid all carry out reverse mould production according to fixed dimension, when using installation, little deviation often due to size between aluminium lid and metal shell, cause between aluminium lid and metal shell, there is tiny gap, cause sealing very poor, if the diameter of aluminium lid is greater than the diameter of the outer box of metal, then aluminium lid is difficult to be installed on metal shell, later stage production efficiency is caused greatly to reduce like this.
Utility model content
In view of this, be necessary to provide good seal performance between a kind of and capacitor metal shell, and be convenient to the power capacitor aluminium lid of installation.
The utility model realizes like this, a kind of power capacitor aluminium lid, be arranged on the metal shell of capacitor, comprise body, described body is discoid aluminium lid, the edge of the periphery of described body is provided with the step groove of ring-type, the center line of the step groove of described ring-type overlaps with the center line of body, described body is provided with the recessed groove of annular, the cross section of described recessed groove is V-shaped, and the center line of the recessed groove of annular overlaps with the center line of body, the radius length of described recessed groove be body radius length 1/1 to three/2nd between.
Further, described body is provided with multiple wiring hole for wiring, and described wiring hole is all in the circle of annular recess groove.
Further, the radius length of described recessed groove is 1/2nd of body radius length.
The advantage of a kind of power capacitor aluminium lid that the utility model provides is: the step groove being provided with ring-type by the edge of the periphery at body, the center line of the step groove of described ring-type overlaps with the center line of body, described body is provided with the recessed groove of annular, the cross section of described recessed groove is V-shaped, and the center line of the recessed groove of annular overlaps with the center line of body, when mounted, described step groove is directly buckled in the metal shell edge of capacitor, and the ring-shaped depression groove that cross section is V-shaped has a flexible effect, body is made to be easy to be fastened on the opening part of capacitor case, and by pressing, can be close-coupled on capacitor metal shell, improve sealing property, and be convenient to install.
