So that locking shrapnel 610 carries out a locking to clamping shrapnel 132；And when 510 contact locking shrapnel 610 of the first shackle member,
Plug-in unit locking protrusion 612 is detached from the first blocked hole 1321, to release a locking.
5 are please referred to Fig.1 to Figure 16, it is seen then that one end of locking shrapnel 610 tilts down certain angle, and above-mentioned plug-in unit
Locking protrusion 612 is installed in the end, so that when locking shrapnel 610 is plugged in clamping gap 133, plug-in unit locking protrusion
612 can smoothly be connected in first blocked hole 1321.
In order to increase the effect once locked, locking shrapnel 610 further includes limit protrusion 613, and limit protrusion 613, which is fixed, to be connected
It is connected to the one end of elastic sheet body 611 far from plug-in unit locking protrusion 612, and plug-in unit locking protrusion 612 is directed away from clamping shrapnel 132
Direction extend；The side of clamping shell 131 towards clamping shrapnel 132 is provided with limited wall 1311；Plug-in unit locking protrusion 612 is solid
When being connected in surely in the first blocked hole 1321,613 contact of limit protrusion is on limited wall 1311.
Preferably, above-mentioned limited wall 1311 is inclined wall, and limited wall 1311 is towards close to the first blocked hole 1321
Direction tilt, limited wall 1311 matches with limit protrusion 613, can stop that locking shrapnel 610 is moved to the left and (namely stop
Dynamic clamping head and quiet clamping head 650 drives locking shrapnel 610 to be moved to the left), avoid plug-in unit locking protrusion 612 from being taken off from the first blocked hole 1321
From the effect that increase is once locked.
6 are please referred to Fig.1, secondary locking is realized especially by with lower structure：
Figure 15 and Figure 16 are please also refer to, clamping shell 131 is provided with the second card close to one end of the first blocked hole 1321
Connect hole 1312；Dynamic clamping head and quiet clamping head 650 is connected in for making plug-in unit locking protrusion 612 fix in the second blocked hole 1312, so that
It obtains locking shrapnel 610 and secondary locking is carried out to clamping shrapnel 132.
As shown in figure 15, the second blocked hole 1312 is located at the left side of the first blocked hole 1321, when a locking, plug-in unit locking
Protrusion 612 is fixed and is connected in the first blocked hole 1321, when male plug part 500 is plugged on mother board 100, the first shackle member 510
It as male plug part 500 moves right, and contacts and extrusion insert locking protrusion 612 so that plug-in unit locking protrusion 612 is to moving up
Dynamic to be detached from the first blocked hole 1321, limit protrusion 613 moves down the limited wall 1311 (Figure 16) that falls off, dynamic clamping head and quiet clamping head 650 to
Locking shrapnel 610 applies active force to the left, so that locking shrapnel 610 is moved to the left, until plug-in unit locking protrusion 612 is blocked
It is connected in the second blocked hole 1312；First shackle member 510 fixation at this time is connected in the first blocked hole 1321, plug-in unit locking protrusion
612 fixations are connected in the second blocked hole 1312, and locking shrapnel 610 applies downward active force towards clamping shrapnel 132,
It avoids clamping shrapnel 132 from moving up and down, so that the first shackle member 510 is reliably fixed in the first blocked hole 1321, prevents public affairs
Plug-in unit 500 is detached with mother board 100.
When male plug part 500 is plugged in mother board 100, one time locking automatically terminates, and dynamic clamping head and quiet clamping head 650 pushes lock automatically
Only shrapnel 610 realizes secondary locking, without manual operation, increases efficiency of assembling, improves assembly convenience, can effectively prevent
Only operating personnel forget secondary locking, increase safety coefficient.
After secondary locking, dynamic clamping head and quiet clamping head 650 always applies towards left active force locking shrapnel 610, ensures locking
Shrapnel 610 is in the lockup state to grafting shrapnel always, further avoids male plug part 500 and is detached with mother board 100, improves card
Connect reliability.
Need dismantle male plug part 500 when, to locking shrapnel 610 right end apply to the right in horizontal direction active force (with
Direction in Figure 16 is reference), using lever principle, at this point, the left end of locking shrapnel 610 moves up to the right simultaneously so that
Plug-in unit locking protrusion 612 is detached from the second blocked hole 1312, so as to release locking shrapnel 610 to the secondary of clamping shrapnel 132
Locking；Subsequent plug-in unit locking protrusion 612 exerts a force downwards under own resilient effect, to which the first shackle member 510 is ejected first
Blocked hole 1321, male plug part 500 can easily be extracted from mother board 100.
