Abstract
The utility model discloses a kind of printed board connector contact piece fixing structure, it comprises pedestal and contact.The installing hole of described pedestal is provided with anti-rotation positioning section, axial location section, support thorn allow dead band.Described contact be provided with cut flat section, diameter of axle section, support thorn section, guide section.When contact presses fit in pedestal, led by guide section, support thorn section and the interference of axial location section, pressing-in force makes support sting section to recover strain by pedestal after axial location section completely, and support thorn section and guide section enter and support thorn and allow dead band.This practicality assembling is simple, can ensure that contact and the reliable of pedestal are fixed, for small―gap suture coordinates between contact with pedestal, be conducive to the spilling of contact heating power heat, be specially adapted to large core number print the structure of connector and fix, this structure can meet that printing connector plugging is soft, thermal diffusivity good, the functional requirement of contact anti-rotation.
Description
Technical field
The utility model relates to contact technique for fixing field, particularly relates to printed board connector.
Background technology
At present, along with the continuous upgrading of domestic model system development scale and speed, each system equipment unit is more and more strong to large core number, light in inserting/pulling force, highly reliable connector demand, and requires that each components and parts manufacturer can complete by fast Development.
Patent CN201038420Y discloses a kind of connector fixing construction (see figure 1), this structure adopts location snap ring (being commonly called as binding ring) to carry out axial restraint to contact, its pedestal installing hole is designed to stepped hole, first locator card ring set is entered in contact when assembling, then will locate in snap ring and contact special tooling feeding base aperture.This constitutional detail quantity and assembly process more, be unfavorable for reducing the production cost of product, be unfavorable for improving the competitiveness of product in market.
Patent CN102064418A discloses a kind of insulation board fixed structure (see figure 2), and this structure adopts in hangnail press-in pedestal, and makes pedestal, in this part, enough strains occur to exit to prevent contact.This structure is without anti-radial rotating function, and heat dispersion is poor, and there is the problems such as large core number product contact engaging and separating force is large.
Summary of the invention
The purpose of this utility model is to provide a kind of printed board connector contact piece fixing structure, and this structure can ensure the reliable fixing of the part such as contact and pedestal, and solves the problems such as anti-rotation, plug is difficult, heat dispersion is poor.
To achieve these goals, adopt following technical scheme: a kind of printed board connector contact piece fixing structure, comprises pedestal and contact; The installing hole of described pedestal is provided with anti-rotation positioning section, axial location section, support thorn allow dead band, described contact be provided with to cut flat section, diameter of axle section, support thorn section, guide section; In described contact press-in pedestal, led by guide section, support thorn section and the interference of axial location section, pressing-in force makes support sting section to recover strain by pedestal after axial location section completely, and support thorn section and guide section enter and support thorn and allow dead band.
Described diameter of axle section and axial location section, support thorn section allows dead band with support thorn, and anti-rotation positioning section flatly intersegmentally all has small―gap suture to coordinate with cutting.
Described anti-rotation positioning section and cut flat section and be squashed structure, can prevent contact radial rotating in pedestal installing hole.
The beneficial effects of the utility model are: need not fixture during assembling, and assembling is simple, can ensure reliably the fixing of contact and pedestal, prevent contact radial rotating; For small―gap suture coordinates between contact with pedestal, be conducive to the spilling of contact heating power heat, the structure being specially adapted to large core count connector is fixed, and can meet the functional requirement that connector plugging is soft, thermal diffusivity is good.
