Description
Technical field
The utility model belongs to field of electronics, more particularly to a kind of anti-loose slotting pin configuration.
Background technology
In electronic enterprises, traditional plug-in appearance and plug-in resistance are all by resistance capacitance or other productions with pin
Product are inserted into the circular hole of PCB, are then welded again, by Pin insertion apertures, always will appear the case where pin bullet comes up, leading
Cause product that cannot be attached to the bottom of PCB, the bad result of appearance is exactly:Product height superelevation, or pin do not enter into circle
Kong Zhong, leading to not conducting, this is also the normal problem of industry, the also matching problem between hole and pin, the diameter in hole
Cannot be too big for the diameter of pin, too big is difficult to fix pin, too small, for automaton, very
Pin is inserted into hole by difficulty, hinders the propulsion of automation, is all much to operate and assemble by hand in industry
Application No. is：CN201710346326.3, the applying date be:20170517, it is entitled：A kind of safety capacitance installation
In the patent of auxiliary installing mechanism in equipment, the auxiliary installing mechanism in a kind of safety capacitance installation equipment is disclosed, is improved
The accuracy that the pin of safety capacitance is inserted into the multiple tooth hole of circuit board by equipment is installed.This safety capacitance installs the auxiliary in equipment
Installing mechanism is provided with linear vibration feeder on workbench, conveyer is provided in the second rack, is additionally provided on workbench
Mechanism is inserted, auxiliary installing mechanism includes Lu Zhi mechanisms and guiding mechanism, and Lu Zhi mechanisms include finger cylinder two, finger cylinder two
With gripping finger two, gripping finger two be connected with for by safety capacitor pin smooth out with the fingers it is straight smooth out with the fingers straight pawl group, the guiding mechanism includes hand
Refer to cylinder three, there is finger cylinder three gripping finger three, gripping finger three to be connected with guide grab group, and the invention improves safety safety capacitance peace
The standby accuracy being inserted into safety capacitor pin in the multiple tooth hole of circuit board of installing improves what installation equipment installed safety capacitance
Stability and efficiency.
Invention content
The purpose of this utility model is exactly to be provided a kind of anti-loose slotting to overcome the problems of the above-mentioned prior art
Pin special fixture, this jig can reduce the fraction defective of automatic insertion-leading foot, greatly improve yields, be more conducive to certainly
Dynamic metaplasia produces
The purpose of the utility model can be achieved through the following technical solutions：
Several multiple tooth holes are arranged in a kind of anti-loose slotting pin configuration, including metal substrate 1, pin 3, the metal substrate 1
2, the pin 3 passes through multiple tooth hole 2, is wrapped along several teeth 4 of hole circumferencial direction setting, the teeth 4 inside the multiple tooth hole 2
Crest 41 is included, plane 42 is set between the teeth 4 and teeth 4.
Preferably, the teeth 4 are equally spacedly distributed around hole circumferencial direction.
Preferably, the radius in the multiple tooth hole 2 is 0.2mm.
Preferably, distance of the plane 42 apart from 2 center of circle of multiple tooth hole is 0.5mm.
Preferably, a diameter of 0.45mm of the pin.
Preferably, the diameter of pin 3 is bigger 0.05mm than the diameter in multiple tooth hole 2.
This utility model is applied in the case of sheet metal inserted component.The circular hole aperture of multiple tooth formation, the thickness of thin slice
It is to have certain relationship, the diameter of pin is greater than the 0.05mm of multiple tooth bore dia under normal circumstances with corresponding leg diameter
Left and right, this is also intended to the thickness of binding slices, and leg diameter confirms.The thickness of the diameter in multiple tooth hole and multiple tooth hole, certainly
The error range allowed is determined, just can more accurately be inserted into sheet metal.
Preferably, the teeth 4 are isosceles trapezoidal structure or isosceles triangular structure.
It is furthermore preferred that the material of the metal substrate is copper material
The utility model is a kind of novel jack structure design, is applied to electronics member of the installation with pin on sheet metal
Part is no longer the structure in hole, but multiple tooth composite structure forms structure as and has the advantages of there are two aspects：
1:Pin be inserted into after, pin again can not negative direction retract, prevent loosening for electronic component；
2:With a certain range of guiding role, the error allowed between pin and hole position can be some larger, to
The fraction defective for reducing automatic insertion-leading foot, greatly improves yields, is more conducive to automated production.

Specific implementation mode
In conjunction with shown in attached drawing, the technical solution of the utility model is further described：
Several multiple tooth holes are arranged in a kind of anti-loose slotting pin configuration, including metal substrate 1, pin 3, the metal substrate 1
2, the pin 3 passes through multiple tooth hole 2, is wrapped along several teeth 4 of hole circumferencial direction setting, the teeth 4 inside the multiple tooth hole 2
Crest 41 is included, plane 42 is set between the teeth 4 and teeth 4.
Wherein, the diameter of the quantity installation warrants pin of teeth 4 and setting, teeth 4 are around hole circumferencial direction etc.
Spacing it is distributed.
Wherein, the diameter of pin is bigger 0.05mm than the diameter in multiple tooth hole or so, this needs the thickness and correspondence of binding slices
Leg diameter confirm that the thickness of the diameter in multiple tooth hole and multiple tooth hole determines the error range of permission.
In this embodiment, it is 0.2mm preferably to select the radius in multiple tooth hole.
Wherein, distance of the plane 42 apart from the multiple tooth hole center of circle is 0.5mm.
In the present embodiment, the preferred a diameter of 0.45mm for selecting pin.
Wherein teeth 4 are isosceles trapezoidal structure, and wherein crest 41 is planar structure.
The teeth 4 are isosceles triangular structure.
In this example, the material that metal substrate is selected is copper material.
This structure is applied to install the electronic component with pin on sheet metal.
Finally it should be noted that：Above example is only to illustrate and unrestricted the technical solution of the utility model, although
