Can be taken out by optical fiber along on fore-and-aft direction, so after damaging occurs in limit base, it is only necessary to change limit base.
Male component housing 8 is the flat block structure that thickness is vertically extending, width extends in left-right direction, intercalation part
Resilient push 21 is provided with part housing, there is resilient push 21 end to be fixedly installed with male component housing 8, head end bullet facing forward
Property the putter body 22 that overhangs, resilient push is arranged at male component housing upper end, and male component housing is outstanding with putter body
Stretch the deformation gap 20 having between end for resilient push elastic deformation along the vertical direction.The projecting end of putter body 22 is provided with
Coordinate the housing Stop structure 24 mobile forward to limit flotation shell with the block of flotation shell 5, top is provided with flotation shell
The locking pushing part 23 of housing Stop structure 24 is pushed away, housing Stop structure 24 is to be convexly equipped in the upper end of putter body 22 in the present embodiment
Projection, be provided with front side of housing Stop structure in putter body 22 in male component housing by respective socket part
By the load portion 25 of Socket casing pushing tow before housing block, load portion 25 is used to be made the outstanding of putter body by Socket casing pushing tow
The housing Stop structure is set to get out of the way flotation shell 5 after stretching end elastic deformation, flotation shell 5 in the longitudinal direction can opposing plug
Part case 8 is moved, and load portion 25 is in the upside of putter body.Can realize that flotation shell is corresponding by said structure to insert
The Z-direction of head part case is floated, and it is fore-and-aft direction that Z-direction is corresponding.
It is provided with male component housing for linking up with the locking slot 28 for coordinating, locking hook with the locking on backboard socket
27 is that guiding movement is assemblied in male component to locking shell 6 along the longitudinal direction with the relocatable elastic hook of slotting elastic tongue 26
On housing 8, it is provided between locking shell 6 and male component housing 8 for applying direction active force facing forward to locking shell
Second spring 10, locking shell 6 has to be used to coordinate to prevent locking spacing with locking hook 27 on fore-and-aft direction
The horizontal pressure unit 29 of abjection and the longitudinal direction for being linked up with pushing tow with locking in the longitudinal direction in locking slot is linked up with to hold
Splenium 30, longitudinal pressure-bearing portion 30 is located at the front side of horizontal pressure unit 29, when daughter board plug and backboard socket are to inserting, locking hook
27 end pushing tow longitudinal direction pressure-bearing portion 30, so as to moved after locking shell 6, after locking hook 27 is entered into locking slot 28, lock
Tight hook no longer pushing tow locking shell, by the active force of second spring, locking shell reach, the horizontal pressure unit in locking shell
29 be moved at locking hook position, and locking hook is prevented by locking slot by the way that the locking hook of horizontal pressure unit 29 pairs is spacing
Deviate from 28, to realize the locking of daughter board plug and backboard socket.The guiding for extending along the longitudinal direction is provided with locking shell
Groove 35, the rear side cell wall 37 of gathering sill 35 is gradually inclined skew wall forward from the bottom to top, is provided with flotation shell positioned at leading
To the barb 36 in groove, barb 36 can be moved in gathering sill 35, and barb 36 is adapted to the rear side cell wall gradient of gathering sill 35, this
When sample group strip flotation shell and moved backwards, barb 36 can backwards be moved with locking shell 6, make horizontal pressure unit by
Removed at locking hook, so as to realize unblock.The unblock of locking shell is realized by rock plate, is highly suitable for daughter board density
Greatly, used in the environment for directly going drawing locking shell without space at all.
The left and right sides of flotation shell is installed on daughter board by X, Y-direction floating mount mechanism, X to it is corresponding be right and left
To, it is above-below direction that Y-direction is corresponding, before X, Y-direction floating mount mechanism include front limited block 16, rear limited block 18 and be connected to,
Connecting pole 15 between limited block afterwards, front limited block 16 is fixed on daughter board by screw 17, and the left and right sides of flotation shell sets
The floating hole 50 that axis extends along the longitudinal direction is equipped with, is offered on the hole wall in floating hole for connecting pole along X to the side wall for loading
Passage, has the flying height on left and right directions and above-below direction between floating hole and connecting pole.Can so prevent daughter board with
When backboard is docked, it is possible that headstock is not to inserting, and the problem of parts is broken.Fig. 7 middle terms 2-1 represents Socket casing.
When using, the daughter board plug 3 is installed on daughter board 4, matched backboard socket 2 is installed on backboard 1, grasped
Making the hand-holdable daughter board of personnel makes daughter board plug with backboard socket to inserting, and X, Y-direction floating mount mechanism can prevent daughter board plug, the back of the body
After problem appearance of the plate socket to not inserting, daughter board plug and backboard socket are to inserting, the locking hook on backboard socket is first hooked
Locking slot on male component housing, the horizontal pressure unit in locking shell pushes down locking hook, daughter board plug and backboard socket
Locking is completed, and as the continuation of daughter board moves forward, flotation shell promotes resilient push, resilient push to continue with male component housing
Mobile forward, gradually, Socket casing makes the projecting end elasticity change down of putter body with the load portion pushing tow in resilient push
Shape, in the presence of Socket casing, the housing Stop structure in putter body can be completely disengaged with flotation shell, before daughter board continues
Move, only flotation shell is moved forward, and daughter board is installed in place, also by Socket casing block, flotation shell is floating flotation shell
During, male component housing can be moved back up untill locking hook serves do again in the presence of the first spring.
When needing daughter board plug to be separated with backboard socket, daughter board is pulled, flotation shell is moved backwards, the barbs hold on flotation shell
After rear wall in locking shell, flotation shell is moved and realizes unblock after can driving locking shell.
In the other embodiments of this connector assembly：Daughter board plug can also be LC plugs；In certain above-described embodiment
Z-direction float, X, Y-direction floating mount mechanism can also be applied in electric connector, and now daughter board plug can be an electric mortiser
Head, when daughter board plug is plug, osculating element is the insulator for being provided with contact；The deformation of the projecting end of putter body
Direction can also be left and right directions, and now putter body can be arranged at the side of male component housing；Housing Stop structure
Can not be a projection cube structure, such as low hierarchic structure after height before the upper surface of putter body is, now shell
Body Stop structure can be made up of the step surface of hierarchic structure；Limit base can also use monomer structure.
