Description
Technical field
The utility model belongs to aluminium electrolytic capacitor product technical field, in particular to bolt type aluminum electrolytic capacitor cover plate
Mosaic texture part-electrode terminal structure.
Background technique
The electrode terminal of bolt type aluminium electrolutic capacitor is inlayed on the cover board using Shooting Technique, and wiring installation passes through
The threaded hole on electrode terminal is located to realize.Currently, electrode terminal generallys use cylindrical structure, it is embedded in deck portion
It mostly uses vehicle to go out the form of several grooves to increase friction area, but in bolt type aluminium electrolutic capacitor wiring installation, is
Biggish power can be applied rotating connection bolt by firmly installing, and electrode terminal easily still occurs in this way and cover board is circumferentially displaced
And it loosens.If loosen, will lead to capacitor stability it is poor in addition occur electrolyte from loosen position gap in ooze out
Influence the normal use of capacitor.
Based on the above, a kind of electrode connection rod structure need to be researched and developed to reduce between electrode terminal and cover board to greatest extent
The possibility of loosening, to eliminate the generation of the above problem.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of stud capacitors electrode terminal, solves wiring
Electrode terminal and cover board is caused to occur to influence bolt type alminium electrolytic condenser due to loosening because applying larger screwing force in installation process
The potential problems that device uses.
To solve the above-mentioned problems, the utility model uses following technical scheme:
A kind of stud capacitors electrode terminal, cylindrical section including end face with threaded hole and inlays with cover board
Groove segment, there is a pair of flat position about cylindrical section axisymmetrical on the periphery of the cylindrical section, and the flat position is one parallel
In the plane of cylindrical section axis；
The groove segment outer surface includes multiple coaxial annular grooves, and the slot bottom of annular groove is provided with a circle muscle, muscle
Surface be twill.
The high height in cylindrical section of the flat position.
The groove segment outer surface further includes the cylinder positioning surface that a plurality of outer diameter is greater than groove segment outer diameter.
The cylinder positioning surface and annular groove are distributed in groove segment outer surface.
The width of the cylinder positioning surface is greater than the width of annular groove.
The width of the muscle is less than the width of annular groove slot bottom, and outer diameter is less than groove segment outer diameter.
The topographic diagonal of the muscle of two neighboring annular groove slot bottom about two annular grooves to divide face equally symmetrical (i.e. parallel
In two annular grooves, and to two equidistant planes of annular groove).
The electrode terminal of the utility model realizes purpose by increasing anti-rotation structure, and anti-rotation structure includes two
Aspect:
1. there is the external cylindrical surface of threaded hole side cylindrical section flat by symmetrical two millings of opening width design of open-end wrench
Position can be reinforced in wiring installation with open-end wrench is opposite with tightening direction to eliminate screwing force and cause electrode terminal and cover board
Between loosen；
2. increasing the muscle class formation with twill in annular groove trench bottom, greatly enhancing anti-rotation according to the principle of tire tread
Kinetic force.
Main anti-rotation structure design rationally, meets die-casting process in the utility model, it is easy to accomplish, meet processing conditions
And requirements of mass production.
Detailed description of the invention
Fig. 1 is binding post structure schematic diagram；
Fig. 2 is partial schematic diagram at binding post muscle；
In figure: being positioned on the flat position 1- connection screw thread, 2-, 31- and position outer circle, 4- interfix outer circle, 5- under outer circle, 32-
Slot bottom setting circle, 6- muscle.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in figure 1 above and Fig. 2, the bolt type aluminium electrolutic capacitor electrode terminal part of the utility model mainly includes
Following geometry: connection screw thread 1, flat position 2, upper positioning outer circle 31, lower positioning outer circle 32, interfix outer circle 4, slot bottom positioning
Circle 5 and muscle 6.It is a pair of flat position about cylindrical section axisymmetrical on the periphery of the cylindrical section of bolt type aluminium electrolutic capacitor
2, flat position 2 is a plane for being parallel to cylindrical section axis, the high height in cylindrical section of flat position 2.Groove segment outer surface includes
Two coaxial annular grooves, the slot bottom of two annular grooves are respectively arranged with the muscle 6 of the dish structure shape of circle protrusion, muscle 6
Surface has twill (i.e. oblique line shape lines), and the topographic diagonal direction of two circle muscle 6 is different, symmetrical about interfix outer circle 4, is formed
Herringbone combines muscle.Groove segment outer surface further includes the cylinder positioning surface that three outer diameters are greater than groove segment outer diameter, i.e., upper positioning is outer
Circle 31, lower positioning outer circle 32, interfix outer circle 4.Upper positioning outer circle 31, lower positioning outer circle 32, interfix outer circle 4 and annular
Groove is distributed in groove segment outer surface.The width of upper positioning outer circle 31, lower positioning outer circle 32 and interfix outer circle 4 is greater than
The width of annular groove.The width of muscle 6 is less than the width of annular groove slot bottom, and outer diameter is less than groove segment outer diameter.
Connection screw thread 1 in cylindrical section end-face helical hole is constant by existing standard, i.e., true according to the requirement in existing standard
Determine the parameter of screw thread, route of the aluminium electrolutic capacitor in circuitry is connected when predominantly wiring is installed；
Flat 2 structure of position is reversely reinforced with open-end wrench with tightening direction when wiring is installed, and tightens connection bolt to eliminate
Power be transmitted to electrode terminal and cover board connecting portion；
Excircle orientation, including upper positioning outer circle 31, lower positioning outer circle 32, interfix outer circle 4, by the outer of groove segment
Form two groove structures on cylinder, three outer circle sections and slot bottom setting circle 5 play electrode terminal positioning on the cover board, fixed
Central role.
Anti-rotation structure: by the muscle structure for increasing herringbone arrangement symmetrical in two groove outer circles, enhancing is prevented
The ability of loosening, rotation occurs between electrode terminal and cover board because being more than ability to bear by external force.
The utility model structural member principle is simple, and smart structural design is motivated, for realizing the target call of invention
It is secure.Outgoing supplier is produced also very convenient, it is only necessary to will can be realized with compression mod restructuring according to engineering drawing, without bright
Aobvious cost increase.Secure for the realization of project objective, cost fluctuation is little, preferably ensures the quality of cover assembly, leads to
Above-mentioned means are crossed to eliminate and cause that loosening occurs between electrode terminal and cover board due to by larger external force to be effective.
