In view of the above-mentioned problems, a kind of pin handware provided by the invention, network filter and filter manufacturing method are logical
Following technical essential is crossed to solve the problems, such as: a kind of pin handware, including pin are arranged on one end of the pin promising
Second wire casing of groove-like structure, the open end of second wire casing is located at the end of pin, and the second wire casing penetrates through pin
Two sides；
By notch end to the slot bottom end of the second wire casing, the groove width of the second wire casing continuously becomes smaller.
The structure of existing network filter as described above designs and manufactures technique, structure design and such technique
Process is not only complicated, and manufacturing process is cumbersome, simultaneously because need to control the elasticity of coil lead during kinking, therefore
There is also the big problems of operation difficulty；Since the lead of magnetic coil is enameled wire, tool used in kinking connects with enameled wire
The part of touching needs to polish smooth, and makes not destroy enameled wire during kinking, influences enameled wire after destroying to avoid enameled wire
Electric property.If the tool (such as tweezers) used is too sharp, lead is also easily set to break or be broken, therefore prior art is also
There are the higher problems of rejection rate.Simultaneously as traditional network filter bond pad locations are winding position, volume is relative to pin
Needle is significantly greater, therefore the problem of there is also the dosages of tin material more, production cost and high labor cost.The two of traditional filter
Spacing between pin is relatively narrow after coiling, therefore the insulation performance between two pins is deteriorated, and easily causes short circuit when in use
Problem, severe one even can cause safety accident occur.
In the present solution, the second wire casing in the pin is used to clamp the lead by drawing on magnetic coil, drawn with realizing
Line is conducted with pin pin.In specific use, according to the diameter of clamped lead, it is set as the opening of the second wire casing
Width numerical value is held to be greater than diameter wire, the groover rot diameter of the second wire casing is less than diameter wire, in this way, lead is going deep into the second wire casing
During, the clamping to lead can be realized by the cell wall of the second wire casing.The groove width of above-described second wire casing is continuous
Become smaller, i.e., are as follows: by open end to the bottom end of the second wire casing, the width of the second wire casing not only consecutive variations, and continuously become smaller, it is above
Continuously become smaller be understood as linearly becoming smaller or it is non-linear become smaller, in actual implementation, such as by the setting of the groove face of the second wire casing
For V-shaped groove type.Using this programme, the groove face of the second wire casing is plane or arcwall face, can effectively avoid or reduce lead
It is broken during being embedded in the second wire casing.The restriction of the first wire casing is also aimed at below and is equal to above second wire casing
Purpose is set.
It not only can effectively avoid using this programme compared to the existing mode that notch and spiral coil are arranged in pin
When such as using tweezers spiral coil, tool itself gives lead bring risk of breakage or surface damage risk；Simultaneously in efficiency,
Embedding connection new model brought by the design of structure used by this programme can be improved 30% or more compared to kinking in efficiency；
Compared to spiral coil mode, the pin that this programme provides not will cause lead to pin after realization is electrically connected with lead
Surrounding space occupies, therefore the filter obtained using this programme, is not in that spacing between two pins of filter exists
Relatively narrow after connecting lead wire, the insulation performance between two pins is deteriorated, and causes the problem of short circuit when in use, or even cause safety
The problem of accident；Using this programme, compared to spiral winding, in wicking, since tie point volume is smaller, therefore required tin amount
Less, therefore this programme is used, also has the characteristics that tin material dosage, control production cost can be reduced.
As the above-described further technical solution of pin handware:

With the connecting pin of lead.Using this programme, not only before each pin is not fixedly connected with the casing, can be limited by winding displacement plate
Determine the relative position between pin, while when completing lead connection, being such as directed to a certain lead, by second wire casing and
First wire casing is completed to clamp to the lead, fixation of the lead relative to shell can be completed, then to lead and pin second
After the cooperation position wicking of wire casing welds and solidifies, then constraint of first wire casing to lead is removed, it is subsequent that tangent line can be completed, cut
Needle operation.Using this programme, in addition to facilitating the relative position between constraint pin, to complete connection of the pin on shell
Outside, it is cooperated by above first wire casing, the first wire casing and the second wire casing when realizing the clamping to lead, in identical clamping
Under effect, lead local pressure is smaller, in this way, can effectively reduce a possibility that lead fixation procedure damages lead；Together
When, according to specific lead parameter, the above tangent line also can be before removing the mutual constraint of lead and the first wire casing, for this feelings
Condition, the first wire casing and the mutual cooperation of the second wire casing can constrain the extending direction of lead in space, in this way, more leads are directed to,
Facilitate and obtains smooth, regular, the accurate lead in position and cut face.
