Expansion radially will necessarily be produced during compression, in order to avoid the hole wall of installing hole limits this expanded radially, need hair button and peace
Dress interporal lacuna coordinates, if direct interference between hair button and installing hole, expands thicker hair button and returns aggravation and install
Contact between hole, extruding, hair button tinsel produces the biggest frictional force, this friction effects hair knob with the hole wall of installing hole
The axial deformation of button and resilience, reduce the axial elasticity of hair button, deteriorates the contact reliability between hair button and printed board, separately
Outer directly interference also can increase the installation difficulty of mao button, because hair button is not rigidity body, axially by bigger pressure
Easily occur during power that unstability, bending, diastrophic hair button cannot again be installed and use.Therefore prior art needs peace
The radial dimension in dress hole more than the radial dimension of hair button, i.e. matched in clearance between hair button and installing hole, and matched in clearance
Defect is mao button easily deviates under the effect of deadweight from installing hole, for the hair button that profile is the least, once carrying,
Occurring in installation process that hair button is deviate from, the hair button of abjection is scattered in device interior and is difficult to find, and for equipment, inside is deposited
It is the most unallowed at unnecessary conductive metal substrate.And the second form, although the setting of locking cap is possible to prevent a mao button
Deviate from by installing hole, but the setting of locking cap also bring problems with, 1, reliability reduce, transmit at signal or electric current
On path, number of parts its transmission reliabilities the most are the lowest；2, overall electrical resistance increases, and the increase of locking cap makes between tonequality plate
Elastic Contact is increased to four (two printed boards and two locking caps by two original (two printed boards and hair button two ends)
Between, two locking caps and hair button two ends), contact resistance is double；3, whole height increases, it is impossible to be applicable to more platelet spacing
Signal or electric current transmission；4, the setting of locking cap so that the parts of product are more, add the cost of product and assemble difficulty
Degree.
