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, other important spare parts of capacitor are installed in container cavity, in manufacturing process, aluminium lid is installed in the process of metal shell, it is the opening part directly aluminium lid being engaged to metal shell, then seal, this sealing mode is outer sealing, need to carry out pressing by other plant equipment, in bonding processes, be easy to make the electronic devices and components of capacitor internal to damage, thus reduce the useful life of capacitor, and outer sealing pattern not only production efficiency is low, and input cost is large.
Utility model content
In view of this, be necessary to provide one to enhance productivity, during sealing, not fragile capacitor internal electronic devices and components, extend the power capacitor shell in capacitor useful life.
The utility model realizes like this, a kind of power capacitor shell, comprise body and aluminium lid, described body is cylindric, one end open, the other end seals, also comprise fixing ring flat-plate, ring-type push pedal and spring, the edge of the openend of described body is provided with ring-shaped baffle, the diameter of described ring-shaped baffle is less than the external diameter of body, and ring-shaped baffle and body coaxial, described fixing ring flat-plate is fixedly mounted on the inwall of body, described ring-type push pedal is between fixing ring flat-plate and ring-shaped baffle, and fixing ring flat-plate, ring-type push pedal is all coaxial with body, described fixing ring flat-plate is identical with ring-shaped baffle size shape, the surrounding of described ring-type push pedal is fixed on described fixing ring flat-plate by arranging multiple described spring, and described multiple spring is uniformly distributed around the axis of described body, described aluminium lid is in the inner chamber of body, and aluminium lid is between ring-type push pedal and ring-shaped baffle, aluminium lid tightly to be pushed by the thrust of spring and is fitted on ring-shaped baffle by described ring-type push pedal.
Further, the wiring that described aluminium lid is provided with for wiring is bored a hole.
Further, the end face center of the sealed end on described body is provided with construction bolt.
The advantage of a kind of power capacitor shell that the utility model provides is: by arranging fixing ring flat-plate, ring-type push pedal and spring, fixing ring flat-plate is fixedly mounted on the inwall of body, ring-type push pedal is between fixing ring flat-plate and ring-shaped baffle, the surrounding of ring-type push pedal is fixed on fixing ring flat-plate by arranging multiple described spring, aluminium lid is being located in the inner chamber of body, and aluminium lid is between ring-type push pedal and ring-shaped baffle, aluminium lid tightly to be pushed by the thrust of spring and is fitted on ring-shaped baffle by described ring-type push pedal, aluminium lid is built-in, directly to be fitted ring-shaped baffle by the thrust of spring, not needing to arrange large-scale extrusion equipment is sealed on body by pressure by aluminium lid, reduce input cost, during sealing, not fragile capacitor internal electronic devices and components, extend the power capacitor shell in capacitor useful life, and install rapidly, can greatly enhance productivity.
