Abstract
A kind of novel capacitor guide pin, including lead, aluminium stalk and aluminium tongue, lead are welded on one end of aluminium stalk, and the other end of aluminium stalk connects aluminium tongue, aluminium stalk and the molding of aluminium tongue integrated punching, and aluminium stalk is connected with the junction in aluminium tongue side face by round-corner transition；The obverse and reverse of aluminium tongue is stamped into plane.The utility model, which obstructs aluminium by cancellation reinforcing rib, can effectively reduce generation short-circuit after capacitor is wound the setting between the obverse and reverse of aluminium tongue being only an inclined-plane and bevelled edge.
Description
Technical field
The utility model relates to a kind of building block of capacitor more particularly to a kind of novel capacitor guide pins.
Background technique
Capacitor is one of a kind of element that can store charge and most common electronic component.Any two are each other
It insulate and all constitutes a capacitor between the conductor (including conducting wire) that is spaced closely together, capacitor passes through capacitance guide needle and other circuits
It is connected.Application No. is 201720386432.X, a kind of disclosed novel aluminium electrolytic capacitor guide pin；It is provided on aluminium tongue adds
Strengthening tendons are provided with down it can be seen that the width of aluminium tongue is greater than the diameter of aluminium stalk from attached drawing 1 in one end of aluminium tongue and aluminium stalk connection
Angle.After aluminium tongue is riveted on the foil of pole, chamfering is very easy to scratch electrolytic paper when being wound with electrolytic paper, so as to cause
Short circuit.Meanwhile after guide pin is powered, the aggregation of charge can be caused on the wedge angle and reinforcing rib in chamfering, to be very easy to breakdown
Electrolytic paper and it is short-circuit.It is also known that the presence of some burrs is inevitably had on electrolytic paper, reinforcing rib meeting after winding
Withstanding these burrs leads to short circuit to pierce through electrolytic paper.
Utility model content
The technical problems to be solved in the utility model, which overcomes the deficiencies of the prior art and provide, a kind of is not easy to cause short circuit
Novel capacitor guide pin.
In order to solve the above technical problems, the utility model proposes technical solution are as follows: a kind of novel capacitor guide pin, including
Lead, aluminium stalk and aluminium tongue, the lead are welded on one end of aluminium stalk, and the other end of aluminium stalk connects aluminium tongue, the aluminium stalk and
The molding of aluminium tongue integrated punching, the aluminium stalk are connected with the junction in aluminium tongue side face by round-corner transition；The aluminium tongue front and
Reverse side is stamped into plane.
Above-mentioned novel capacitor guide pin, it is preferred that the aluminium stalk and the positive junction of aluminium tongue and aluminium stalk and aluminium tongue
Reverse side junction is stamped out an inclined-plane.
Above-mentioned novel capacitor guide pin, it is preferred that the two sides setting camber or semi-circular of the aluminium tongue.
Above-mentioned novel capacitor guide pin, it is preferred that the two sides beveling of the aluminium tongue and aluminium stalk connection one end is formed with tiltedly
Trimming；The width of described bevelled edge one end is identical as the diameter that aluminium obstructs, and obstructs transition with aluminium by fillet and connect；The beveling
Side is connect with the side of aluminium tongue by arc-shaped transition.
Above-mentioned novel capacitor guide pin, it is preferred that the length of the bevelled edge is 1 to the two/10ths of aluminium tongue length
/ mono-.
Above-mentioned novel capacitor guide pin, it is preferred that the bottom of the aluminium tongue is arc-shaped or semicircle.
In the present invention, aluminium stalk and aluminium tongue directly carry out punching press, aluminium stalk and the positive junction of aluminium tongue and aluminium stalk with
The reverse side junction of aluminium tongue is stamped out an inclined-plane.Stamp out on the aluminium tongue come without reinforcing rib, on aluminium stalk also without
Reinforcing rib is thus not in that reinforcing rib withstands burr and the case where burr pierces through electrolytic paper occurs, while reinforcing rib is not yet
The case where will appear accumulation, reduces electrical breakdown.
In the present invention, since aluminium stalk is stamped and formed out aluminium tongue, the width for being thus bound to cause aluminium tongue is greater than
Aluminium stalk, and traditional way is that chamfering is formed on aluminium tongue, the setting of chamfering so that be easy to scratch electrolytic paper when winding,
Simultaneously in the state of energization, the aggregation of charge is easy to appear to puncture electrolytic paper and short circuit occurs.In the present invention,
Chamfering is become the bevelled edge of an approximate arc in the present invention by this problem of the setting very good solution of bevelled edge, this
Sample is just not easy to scratch electrolytic paper, is also not easy to cause the aggregation of charge.
Compared with the prior art, the advantages of the utility model are: the present invention makes aluminium stalk and aluminium by cancelling reinforcing rib
Be only between the obverse and reverse of tongue an inclined-plane and bevelled edge setting can effectively reduce it is short after capacitor winding
The generation on road.

Specific embodiment
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to the utility model
Work more comprehensively, meticulously describes, but the protection scope of the utility model is not limited to embodiment in detail below.
It should be strongly noted that when to be described as " be fixed on, be fixed in, be connected to or be connected to " another for a certain element
When on element, it can be directly fixed, affixed, connection or is connected on another element, be also possible to by connecting among other
Fitting is indirectly fixed, affixed, connects or is connected on another element.
Unless otherwise defined, all technical terms used hereinafter and the normally understood meaning of those skilled in the art
It is identical.Technical term used herein is intended merely to the purpose of description specific embodiment, and being not intended to limitation, this is practical
Novel protection scope.
