Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-5, the present invention provides a kind of technical solution: a kind of PIN needle connector, PIN needle connector 3 are metal
One three stage structure made of material, including bottom stage position-arresting disk 32, interlude spring beam 33 and top section press from both sides syringe needle 34,
PIN needle connector 3 is inserted into the connector mounting hole 11 on wiring board 1, the upper surface of position-arresting disk 32 and the copper foil on wiring board 1
It is in close contact, specifically, the outer diameter of position-arresting disk 32 is greater than the diameter of connector mounting hole 11, prevents PIN needle connector 3 from entirely inserting
Enter in connector mounting hole 11, subsequent extraction is facilitated to continue to use, further, folder 34 lower part anchor ring overall diameter of syringe needle is greater than bullet
Property beam 33 overall diameter, i.e. the lower part anchor ring of folder syringe needle 34 protrudes from spring beam 33, presss from both sides and formed between syringe needle 34 and spring beam 33
One card slot, this card slot are used to be clamped with wiring board 1, and height and 1 thickness of wiring board of spring beam 33 match, and PIN needle connects
It connects device 3 to be inserted into connector mounting hole 11, in the lower part anchor ring barb assist side 1 for pressing from both sides syringe needle 34, prevent because of PIN connector ruler
It is very little it is smaller it is inadequate with 31 inner wall frictional force of PIN needle mounting hole caused by fall off, through offering PIN in the middle part of PIN needle connector 3
Needle mounting hole 31, PIN needle mounting hole 31 are an inclined-planes in 34 sections of syringe needle of folder of inner wall, and PIN needle 2 is inserted into PIN needle mounting hole
After 31, the inclined-plane of PIN needle 2 and folder 34 inner wall of syringe needle is interference fitted, and formation effectively contacts and generates certain frictional force, simultaneously
The meeting compression clamp syringe needle 34 of PIN needle 2 deforms, and the deformation of folder syringe needle 34 can force in 33 outside wall surface of spring beam and connector mounting hole 11
Wall surface forms certain contact, to make effectively transmit electric current letter between wiring board 1, PIN needle connector 3 and PIN needle 2
Number, further, PIN needle 2 and position-arresting disk 32 and spring beam 33 are clearance fits, between PIN needle 2 and PIN needle connector 3
Frictional force of the frictional force between PIN needle 2 and folder syringe needle 34, thus can control contact engaging and separating force, PIN needle 2 will not be bent
Deformation, will not damage wiring board 1, and reuse rate is high.
Specifically, in the present embodiment, 32 outer diameter of position-arresting disk is the 110%-115% of 11 internal diameter of connector mounting hole, have
Limiting to PIN needle connector 3 for effect, will not entirely submerge in wiring board 1, facilitate subsequent extraction.
Specifically, in the present embodiment, 33 height of spring beam is the 100%-105% of 1 thickness of wiring board, spring beam 33 is thick
Degree is the 95%-100% of the difference of 2 maximum outside diameter of connector mounting hole 11 and PIN needle.
Specifically, in the present embodiment, folder 34 lower part anchor ring outer diameter of syringe needle is no more than 33 top loop outer diameter of spring beam
5%, i.e., the card slot size formed between folder syringe needle 34 and spring beam 33 should not be too large, and otherwise PIN needle connector 3 is difficult do not sending out
Mounting hole is inserted into the case where raw or generation very little plastotype deformation.
Specifically, in the present embodiment, slope plane forms 85 ° -90 ° of inclined-plane with the horizontal plane perpendicular to spring beam 33
Angle a, power when PIN needle 2 is inserted into mainly is influenced by folder syringe needle 34 with its frictional force size, and frictional force and normal pressure are at just
Than, therefore contact engaging and separating force can be controlled by the size of control folder 34 ramp angle a of syringe needle, and bevel angle a is kept
85 ° -90 ° can control contact engaging and separating force in rationally comfortable range, more convenient plug.
Specifically, in the present embodiment, folder syringe needle 34 is axisymmetric four fractions structure, have the advantages of simple structure and easy realization low
Cost volume production.
Installation steps: as shown in Figures 2 and 3, installation PIN needle connector 3, PIN needle connector 3 are inserted on wiring board 1 first
Connector mounting hole 11 in, due to the deformation of spring beam 33, can very easily be inserted into, after insertion, folder syringe needle 34 block line
Road plate 1 prevents from falling off；Then PIN needle 2 is installed, as shown in Figures 4 and 5, after PIN needle 2 is inserted into PIN needle mounting hole 31, press from both sides syringe needle 34
The inclined-plane of inner wall will form with PIN needle 2 and effectively contact, and generate a certain size frictional force, make 32 upper surface of position-arresting disk and line
Plate 1 copper foil in road is in close contact, meanwhile, the deformation of folder syringe needle 34 can force to be avoided and 31 inner wall of PIN needle mounting hole outside spring beam 33
Face forms certain contact, thus be press from both sides syringe needle 34, three pressing contact positions of position-arresting disk 32 and spring beam 33 can effectively pass
Pass current signal.
PIN needle connector 3 provided by the present application, structure is simple, convenient disassembly, is easy to volume production, and contact engaging and separating force control is simple, inserts
The copper foil that will not be damaged on wiring board 1 is pulled out, may be reused.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
