Abstract
The utility model provides a kind of winding needle producing capacitor, it includes winding seat, volume pin, sleeve, wherein, winding seat is cylindrical, its center, one end is provided with sleeve, other end seat surface is provided with two symmetrical volume pin holes, and volume pin is identical two of structure, and symmetry is assemblied in corresponding volume pin hole; Between two silver lap pins after assembling, reserved certain distance forms aluminium foil groove, and described volume pin main body is strip, and its cross section is trapezoidal, and the trapezoidal faces of volume pin length direction both sides is the arc of evagination.This device is after employing such scheme, when rolling, aluminium foil and electrolytic paper to be led transition by winding needle cambered surface, make close contact between the capacitor layers after rolling time, effectively reduce the electric capacity volume after making, winding needle damages and can directly change, easy to operate, practical.
Description
Technical field
The utility model relates to a kind of capacitance technology field, refers in particular to a kind of winding needle producing capacitor.
Background technology
Electrolytic capacitor is the fuse that combination is coiled into a toroidal in a winding manner by positive pole aluminium foil, negative pole aluminium foil, electrolytic paper, guide pin, then injects and carry out aging after mechanical encapsulation again after electrolyte installs glue lid aluminum hull additional and formed.Existing electric capacity winding needle is all adopt square structure, this structure is when winding capacitance, because winding needle is square, and electric capacity is cylindric after winding, cause when reeling and between winding needle noncontact face, easily being formed gap and distortion by rolls of aluminum foil, after causing reeling, electric capacity core body volume increases, and easily produces seepage, greatly affects the result of use of electric capacity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy to operate, practical winding needle producing capacitor.
For achieving the above object, technical scheme provided by the utility model is: a kind of winding needle producing capacitor, it includes winding seat, volume pin, sleeve, wherein, winding seat is cylindrical, and its center, one end is provided with sleeve, and other end seat surface is provided with two symmetrical volume pin holes, volume pin is identical two of structure, and symmetry is assemblied in corresponding volume pin hole; Between two silver lap pins after assembling, reserved certain distance forms aluminium foil groove, and described volume pin main body is strip, and its cross section is trapezoidal, and the trapezoidal faces of volume pin length direction both sides is the arc of evagination.
One-body molded inside described volume pin hole have location notch, and volume pin one end is provided with the positioning strip matched, and the volume pin after sleeve is located by positioning strip.
The face that two described silver lap pins are wider is adjacent, and between its adjacent surface, reserved certain distance forms aluminium foil groove.
The utility model is after employing such scheme, when rolling, aluminium foil and electrolytic paper to be led transition by winding needle cambered surface, make close contact between the capacitor layers after rolling time, effectively reduce the electric capacity volume after making, winding needle damages and can directly change, easy to operate, practical.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the fractionation schematic diagram of Fig. 1.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2, a kind of winding needle producing capacitor described in the present embodiment includes winding seat 1, volume pin 2, sleeve 3, wherein, winding seat 1 is cylindrical, and its center, one end is provided with sleeve 3, and other end seat surface is provided with two symmetrical volume pin holes 4, volume pin 2 be identical two of structure, and symmetry is assemblied in rolls up in pin hole 4 accordingly; One-body molded inside described volume pin hole 4 have location notch, and volume pin 2 one end is provided with the positioning strip matched, and the volume pin 2 after sleeve is located by positioning strip; Between two silver lap pins 2 after assembling, reserved certain distance forms aluminium foil groove 5, described volume pin 2 main body is strip, its cross section is trapezoidal, the trapezoidal faces of volume pin 2 length direction both sides is the arc of evagination, the face that two described silver lap pins 2 are wider is adjacent, and between its adjacent surface, reserved certain distance forms aluminium foil groove 5.This device is after employing such scheme, when rolling, aluminium foil and electrolytic paper to be led transition by winding needle cambered surface, make close contact between the capacitor layers after rolling time, effectively reduce the electric capacity volume after making, winding needle damages and can directly change, easy to operate, practical.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection range of the present utility model.
