Description
Technical field
The present invention relates to a kind of screw structural, particularly relate to a kind ofly when the printed circuit board (PCB) assembling operation, promote the screw structural of the tool baffle ring of stability.
Background technique
Fig. 1 to Fig. 5 is respectively schematic representation one, schematic representation two, schematic representation one, schematic representation two and the schematic representation three of existing known screw structural when assembling of existing known screw structural.General existing commonly using when being incorporated into screw on the printed circuit board (PCB), it is a screw 5 that will have screw terminal 51, screw rod 52 and sleeve 53, in the perforation 71 of screw 5 sleeves 53 corresponding to a printed circuit board (PCB) 7, press down again screw terminal 51, the jagged flange 531 of screw 5 sleeves 53 tools is installed with in perforation 7
In 1 so that screw 5 be incorporated on the printed circuit board (PCB) 7.
Although the above-mentioned existing screw structural of commonly using can be incorporated into screw 5 in the perforation 71 of printed circuit board (PCB) 7; but screw 5 is with the directly corresponding perforation 71 of its sleeve 53 when arranging; its screw terminal 51 can't compress with sleeve 53 and set firmly; so 51 of sleeve 53 and screw terminals are easily slipped up because crack between therebetween produces to rock to cause to aim at easily when being incorporated into printed circuit board (PCB) 7; and employed screw 5 volumes are all less with perforation 71 apertures; therefore; when the flange 531 of screw 5 sleeves 53 wants to be located at perforation 71 the time; also produce easily error; make the flange 531 of sleeve 53 can't aim at smoothly perforation 71; cause the bad machine plate that causes of printed circuit board (PCB) pressing to damage; and when the flange 531 of sleeve 53 can't once be located at perforation 71 the time; often can be inaccurate because of printed circuit board (PCB) 7 plane precisions; and the flange 531 that makes sleeve 53 is arranged at perforation 71 o'clock; can't be pressed together on fully in the perforation 71, and have easily skew and crooked phenomenon to produce.In addition, use pressing mode assembling screw 5 must take each screw 5 and do pressing, so the various shortcoming of existing known techniques can't make the efficient optimization of the widely used surface mount technology of industry when assembling screw 5.
This shows that above-mentioned existing screw structural obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, finished by development but have no for a long time applicable design always, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious wish of relevant dealer solves.Therefore how to found a kind of screw structural of novel tool baffle ring, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
