Utility model content
The purpose of this utility model is to provide a kind of PIN needle mounting structure, solves easy causing hole pull-up when existing PIN needle is installed and falls to causing the problem of product rejection.
For solving the problem, the utility model embodiment provides a kind of PIN needle mounting structure, comprises printed circuit board, and described printed circuit board is provided with PIN hole, inside described PIN hole cylinder and PIN hole bottom surface periphery printed circuit board on metallic conductor; Be installed with suitable PIN needle in described PIN hole, described PIN needle comprises shank, and described shank one end extends connection round platform, and outside described round platform, cylinder is provided with flange, described round platform and PIN hole interference fit.By designing new PIN needle mounting structure, when squeezing into PIN needle, flange and Hua Ceng contact position, hole part metals conductor is only had easily to come off, but squeeze into rear PIN hole can be out of shape and touch with the non-flange part tap of round platform, ensure that the PIN needle conduction good with PIN hole is connected, improve the one-shot forming rate that PIN needle is installed, solve PIN needle when installing, hole, PIN hole layer is easily squeezed and peels off, the defect of the electrical connection open circuit of thus caused PCB levels.
Optionally, described flange extends along round platform bus.
Optionally, described flange has three at least.By designing three with upper flange, be more conducive to round platform and PIN hole interference fit.
Optionally, described flange length is equal with round platform bus length.Take to this architecture enhance the intensity squeezed into rear PIN needle and install, prevent PIN needle from departing from.
Optionally, described flange seamed edge takes R angle excessive.Excessively its production technology is easier to take R angle, low production cost.
Optionally, described round platform center line is PIN pore radius 1.05-1.10 times to the vertical range of seamed edge.Take this designed distance, PIN needle to be connected with PIN hole more closely after squeezing into, and ensure that the PIN needle conduction good with PIN hole is connected.
Optionally, described round platform is provided with overlap away from shank one end outer ledge.In the design of round platform one end, during installation between overlap press-in PIN needle and PIN hole, promote PIN needle and be connected with the conduction between PIN hole.
Compared with prior art, the technical program has the following advantages:
This is by designing new PIN needle mounting structure, when squeezing into PIN needle, flange and Hua Ceng contact position, hole part metals conductor is only had easily to come off, but squeeze into rear PIN hole can be out of shape and touch with the non-flange part tap of round platform, ensure that the PIN needle conduction good with PIN hole is connected, improve the one-shot forming rate that PIN needle is installed, solve PIN needle when installing, hole, PIN hole layer is easily squeezed and peels off, the defect of the electrical connection open circuit of thus caused PCB levels.At round platform one end design overlap, during installation between overlap press-in PIN needle and PIN hole, promote PIN needle and be connected with the conduction between PIN hole.Flange seamed edge takes R angle, and excessively its production technology is easier, low production cost.The utility model structure is simple, convenient for production, with low cost.

Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, clear, complete description is carried out to the technical solution of the utility model.
Embodiment: the utility model embodiment provides a kind of PIN needle mounting structure, comprises printed circuit board 3, described printed circuit board 3 is provided with PIN hole 7, inside described PIN hole 7 cylinder and PIN hole 7 bottom surface periphery printed circuit board 3 on metallic conductor 1; Be installed with suitable PIN needle 2 in described PIN hole 7, described PIN needle 2 comprises shank 22, and described shank 22 one end extends connection round platform 21, and outside described round platform 21, cylinder is provided with flange 5, described round platform 21 and PIN hole 7 interference fit.By designing new PIN needle mounting structure, when squeezing into PIN needle 2, flange 5 and Hua Ceng contact position, hole part metals conductor is only had easily to come off, but squeeze into rear PIN hole 7 can be out of shape and with round platform 21 non-flange 5 part contact, ensure that PIN needle 2 conduction good with PIN hole 7 is connected, improve the one-shot forming rate that PIN needle is installed, solve PIN needle when installing, hole, PIN hole layer is easily squeezed and peels off, the defect of the electrical connection open circuit of thus caused PCB levels.Described flange 5 extends along round platform 21 bus.Described flange 5 has three at least.By designing three with upper flange 5, be more conducive to round platform 21 and PIN hole 7 interference fit.Described flange 5 length is equal with round platform 21 bus length.Take to this architecture enhance the intensity squeezed into rear PIN needle and install, prevent PIN needle 2 from departing from.The present embodiment adopts 4 flanges, and flange seamed edge 6 takes R angle excessive.Described flange seamed edge 6 takes R angle excessive.Excessively its production technology is easier to take R angle, low production cost.Described round platform 21 center line is PIN hole 7 radius 1.05-1.10 times to the vertical range of seamed edge.Take this designed distance, PIN needle 2 to be connected with PIN hole 7 more closely after squeezing into, and ensure that PIN needle 2 conduction good with PIN hole 7 is connected.The present embodiment takes round platform 21 center line to the vertical range of seamed edge to be 1.06 times of PIN hole 7 radius.Described round platform 5 is provided with overlap 11 away from shank 22 one end outer ledge.At round platform 21 one end design overlap 11, during installation, overlap 11 is pressed between PIN needle 2 and PIN hole 7, promotes PIN needle 2 and is connected with the conduction between PIN hole 7.Overlap 11 is provided with near the present embodiment flange 5.
