Description
Technical field
The utility model relates to capacitor arrangement technical field, specially a kind of extraction electrode and locating cover integral type capacitor
Device structure.
Background technique
There are many kinds of the encapsulation of capacitor and lead-out mode, common a kind of cylinder in the application of power electronic capacitor
Metal shell, top electrodes are drawn, the thin film capacitor of plastics locating cover insulation.The capacitor of this construction packages can very big effect
Space is utilized to rate, it is easy for installation, it may be readily formed as standardized component and select to combine for client.
But such capacitor is primarily present two production technology problems in production now:
First is that locating cover will be fitted close with metal shell and leave no gaps, at present to guarantee capacitor sizes and leakproofness
The measure that industry is generally taken in production is that a circle silica gel is smeared on the contact surface of locating cover and shell, will with pneumatic shuttle
It depresses with the assembled locating cover of capacitor semi-finished product, is fitted close with metal shell, since silica gel solidification needs 5-6h, simultaneously
The non-encapsulating of capacitor internal is fixed, and after capacitor takes out in pneumatic shuttle, is easily rebounded with the assembled locating cover of metal shell,
There are gaps.So we have in capacitor before taking out in gland equipment, adhesive tape is wrapped in locating cover and shell
On, to prevent from springing back upwards in silica gel solidification prelocalization lid.Product is made to waste very big time cost and occupy very big in this way
Cost of labor, cannot achieve automatic assembly line production, and twine adhesive tape tear tape every time, gluing, significantly waste material reduce
Efficiency increases product not environmentally risk.It is specifically shown in Fig. 1, Fig. 2, shown in Fig. 3.
Second is that extraction electrode pin pitch and exposed size are particularly important due to client installation requirement, how to guarantee to draw electricity
The precision of pole pin pitch and exposed size is always the bottleneck for being difficult to break through when making such capacitor, and current solutions are fixed
Position lid, extraction electrode assembling after, before infusion epoxy resin with dedicated fixture guarantee electrode foot away from exposed size, to epoxy
Fixture is removed after resin solidification again.Such method causes great inconvenience, each upper fixture dismounting fixture waste to production process
In many working hours, the keeping and replacement of fixture are also pretty troublesome, often have reworks and defective products to occur, are completely unsuitable for high-volume
Modernize flow line production mode.If manual operation control is bad when production or uses bad fixture, will occur bulk
Size is bad, causes bulk loss not only difficult to install, and installation poor contact reluctantly, also gives the long-term fortune of circuitry sometimes
Bring security risk.
Summary of the invention
It is at high cost in existing capacitor production process in order to solve, the problem of low efficiency, unstable quality, the utility model
Provide a kind of extraction electrode and locating cover integral type capacitor arrangement, can save the cost, shorten the production cycle, improve life
Produce efficiency, Improving The Quality of Products stability.
Its technical solution is such that a kind of extraction electrode and locating cover integral type capacitor arrangement comprising shell, electricity
Container core, potting compound and extraction electrode, which is characterized in that the shell is cylindrical shell open at one end, the cylindrical shell
The opening of body is set with locating cover, forms the chamber for installing the capacitor core body inside the locating cover and the cylindrical shell
Body is fixed with extraction electrode on the locating cover, and the extraction electrode connects the capacitor core body by copper strips.
It is further characterized by the locating cover is plastic lid, and the extraction electrode and the locating cover are molded into one
Body structure, the shell are metal shell；
The cylindrical shell opening outer wall is provided with inside positioning groove, the downward outer peripheral surface of locating cover be provided with
The annular tongue of the positioning groove cooperation or the salient point arranged in a ring.
After the structure of the utility model, extraction electrode is directly integrally fixed with locating cover, efficiently solves life
Produce in manufacturing process electrode foot away from exposed Assurance of Size problem, reduce the artificial of unnecessary fixture cost and upper dismounting fixture
Cost, avoid because manual operation or fixture it is bad brought by bulk loss, substantially increase production efficiency, improve product
Quality meets full-automatic flow line production requirement；Further, by the downward outer peripheral surface annular tongue of locating cover or in ring
Positioning groove on the salient point and cylindrical shell of shape arrangement realizes clamping fixed, it is possible to prevente effectively from locating cover is assembled with capacitor
Rebound afterwards avoids the use of silica gel and adhesive tape, further saves unnecessary material cost and gluing twines adhesive tape tear tape
The cost of labor of generation shortens life cycle of the product, and effectively prevent because human factor generate it is bad, greatly mention
The high qualification rate of product.

Specific embodiment
As shown in Fig. 4 to Figure 11, a kind of extraction electrode and locating cover integral type capacitor arrangement comprising shell 1, capacitor
Device core 3, potting compound 4 and extraction electrode 22, shell 1 are cylindrical housings open at one end, and are metal shell, shell 1
Opening be set with locating cover 21, the cavity of installation capacitor core body 3, locating cover 21 are formed inside locating cover 21 and shell 1
On be fixed with extraction electrode 22, extraction electrode 22 connects capacitor core body by copper strips 23.Specifically, locating cover 21 is plastics
Lid, extraction electrode 22 be molded with locating cover 21 it is into a single integrated structure, shell 1 be metal shell.
1 opening outer wall of shell is provided with inside positioning groove, and the downward outer peripheral surface of locating cover 21 is provided with and positioning groove
The annular tongue of cooperation or the salient point arranged in a ring.The locating cover 21 of plastics is changed to inside the housing from 1 outside of shell is downward
Downward, the shell 1 and 3 top of capacitor core body exit and metal are completely insulated, considerably increase climbing for two exits
Electrical distance solves the insulation hidden danger of capacitor core body 3 Yu shell 1, improves the security performance of capacitor, installs for capacitor
Provide very big convenience.
The utility model is by improving capacitor arrangement, so that pipeline system automated production may be implemented in product, not only
