Description
Technical Field
The invention relates to a fuzz button connector.
Background
The fuzz button connector is in contact with the corresponding printed board bonding pad through the axial end face of the fuzz button, and vertical interconnection among the printed boards is achieved.
The fuzz button connector comprises a fuzz button and an insulator, and a mounting hole for mounting the fuzz button is formed in the insulator. The fuzz button is required to be prevented from falling off from the mounting hole after being mounted on the insulator, and the fuzz button is usually realized by setting the inner diameter of the mounting hole to be smaller than the outer diameter of the fuzz button so as to enable the fuzz button to be in interference fit with the mounting hole.
Although this attachment method can prevent the fuzz button from falling off the attachment hole, there are some problems: firstly, because the hair button is not a rigid body, the interference fit installation difficulty of the hair button and the installation hole is high, and after the hair button is installed, the hair button can rebound phenomena such as creep deformation and the like after shrinkage deformation, and finally the length of the hair button extending out of two ends of the installation hole can not be ensured to be reliably contacted with a printed board; in addition, the wool button connector is when using, the wool button can be compressed by the printing board at both ends and take place elastic deformation, realize the reliable contact between wool button and the printing board under the effect of axial elasticity power, the wool button can produce radial inflation when being compressed by the axial, and if be interference fit between wool button and the mounting hole, the contact and the extrusion between inflation thickening wool button can aggravate and the mounting hole, will produce very big frictional force between wool button and the mounting hole, this frictional force can influence the axial resilience of wool button, reduce the axial elasticity of wool button, and then worsen the contact reliability between wool button and the printing board.
One chinese patent application publication No. CN106099488A published on 11/9/2016 describes a fuzz button connector and an insulator thereof, one embodiment of the fuzz button connector includes an insulator and a fuzz button, a mounting hole for mounting the fuzz button is provided on the insulator, and a hole wall of the mounting hole includes an upper clearance fit section in clearance fit with an upper end of the fuzz button, a lower clearance fit section in clearance fit with a lower end of the fuzz button, and an interference fit section located between the upper and lower clearance fit sections and in interference fit with a middle portion of the fuzz button. The interference fit section in the hair button connector ensures that the hair button cannot fall off from the mounting hole, and because the upper end and the lower end of the hair button are in clearance fit with the mounting hole, when the printed board compresses the hair button, enough space is reserved in the mounting hole for radial expansion of the hair button, and great friction force cannot be generated between the hair button and the mounting hole, so that the contact reliability between the hair button and the printed board cannot be influenced. The mounting holes of the other embodiment of the fuzz button connector are arranged in an equal diameter mode, the fuzz button adopts a stepped shaft structure, the part with the larger diameter is in interference fit with the mounting holes, and the part with the smaller diameter is in clearance fit with the mounting holes.
Although the shedding problem of the hair button and the unreliable problem of contact caused by interference fit of the hair button and the whole mounting hole can be solved by the two embodiments of the hair button connector, the interference fit section on the hair button is bound to generate compression deformation when the hair button is mounted because one section of the hair button and the mounting hole is interference fit, the creep deformation can be generated along with the lapse of time after the compression deformation of the hair button, the direction of the creep deformation can not be determined, so that the length of the insulator extending out of the two ends of the hair button when the hair button is finally used can not be ensured, and further the uncertainty of the contact pressure when the hair button is connected with a printed board is caused, and the contact reliability of the hair button and the printed board is influenced.
