Embodiment
The implementation of mother daughter board connector component is for example shown in Fig. 1 ~ 5：Including the use of when the daughter board that is arranged on corresponding daughter board insert
Head and using when be arranged at backboard socket on corresponding backboard.Daughter board plug includes shell body 6, passes through the first bullet on shell body 6
Floating assembly has locking shell 7 to property part along the longitudinal direction, and the first elastic component is spring.It is oriented to along the longitudinal direction in locking shell 7
Movement is provided with integrally-built male component housing 8, and male component housing is insulator structure, is set in male component housing
There is two rows Plug contact unit, include spaced apart three front ends in left-right direction per socket head contact unit
For the Plug contact unit 1 of inserted terminal, each Plug contact unit 1 is floated along the longitudinal direction by the second elastic component to be arranged at
In male component housing, the second elastic component is spring, and Plug contact unit 1 is optical fiber contact unit in the present invention.Plug
The locked groove for playing pawl for the locking with socket and coordinating is provided with part case, locking can be played pawl and is limited in by locking shell 7
Locked in locked groove so as to realize.The guide groove that guide direction extends in left-right direction is provided with shell body, along a left side in guide groove
Right direction guiding movement is equipped with shell body block 4, and shell body block 4 is the left side of metalwork, shell body block 4 and guide groove
Top is provided with the back-moving spring 5 arranged before and after two between cell wall.The upper end of guide groove is provided with cover plate 11, the right front ends of guide groove
Set jagged, be provided with the bearing member 3 passed by breach on shell body block, bearing member includes extending along the longitudinal direction perpendicular
Bar and the cross bar extended in left-right direction, cross bar are connected with shell body block, and the front end of montant is provided with for by Socket casing
Pushing tow and make shell body block towards the block load portion 2 that moves left.Between three are provided with male component housing in left-right direction
Every the part case block 9 of setting, there are corresponding shell body block two to be used to keep off with two part case blocks on right side
Only coordinate to limit the block projection 10 that male component housing moves backwards, when shell body block is towards when moving left, block is raised
10 can be moved in the gap 20 between connected two part case blocks, so as to get out of the way part case block, now plug
Part case no longer by shell body block block, male component housing can opposite shell body move backwards.
Backboard socket includes Socket casing 14, female component housing 15 and the socket being correspondingly arranged with Plug contact unit
Contact unit 16, female component housing are the insulator structure of monoblock type, are provided with female component housing and are used for and plug
The locking bullet pawl 13 that locked groove and locking shell on part case coordinate, wherein locking plays pawl and the cooperation of locked groove and locking shell
Relation belongs to prior art, is no longer discussed in detail herein.The block being provided with Socket casing on pushing tow shell body block
The pushing tow inclined-plane in load portion.Plug contact unit is male in the present embodiment, and socket contact unit is female.
In use, backboard socket is installed on backboard, daughter board plug is installed on daughter board, promotes daughter board, daughter board is with lock
Tight housing and male component housing are moved towards backboard socket together, and locking shell, which is locked, to be played pawl pushing tow and then move, and works as locking
After bullet pawl is stuck in locked groove, acted on by the first elastic component, locking shell is moved forward and locking is played into pawl and is limited in locked groove, and realization is inserted
The locking of head contact unit and socket contact unit.When daughter board continues to push ahead, the pushing tow inclined-plane on Socket casing
Can pushing tow block load portion, make shell body block transverse shifting, when the block projection on shell body block be moved to it is two neighboring
After in gap between part case block, shell body block no longer stops male component housing, and now male component housing is just

Between, provide larger adjustment space for the rigging position of daughter board and backboard.
Synchronously lock or unlock using integrally-built female component housing, male component housing, during plug, make plug more
It is smooth, steady.Due to elasticity need not be utilized to realize block and the unblock to male component housing, therefore shell body block can
To be made up of metalwork, intensity is big, it is important that block is raised can to have very big load-carrying surface between part case block, make
It is more reliable to the block between part case block to obtain shell body.
In other embodiments of the invention：Block load portion can also be arranged at the left side of shell body block, now outer
Housing block can be unlocked by moving right to part case block；The number of part case block can also be as needed
Selected, such as one, two or other numbers, now the block projection number on shell body block can also adaptability
Change；Shell body block can also be nonmetal parts, such as plastics；Bearing member can not also be set, such as block load
Portion is located on the side of shell body block, the side of the direct pushing tow shell body block in the pushing tow inclined-plane on Socket casing；Work as daughter board
When not using the locking mechanism of locking shell formula between plug and backboard socket, such as adopted between daughter board plug and backboard socket
During with by frictional force direct-plug structure, locking shell can not be set, and now the first elastic component can be arranged directly on shell body
Between male component housing；First elastic component, the second elastic component may not be spring, for example can be in fore-and-aft direction
The upper rubber for producing elastic deformation or other elastomers；Daughter board plug and backboard socket can also be electric connector；Plug contact
Part unit can also be female, and now socket contact unit is male.
The implementation of daughter board plug is for example shown in Fig. 1 ~ 3：The concrete structure of daughter board plug and above-mentioned each mother daughter board connector component
Daughter board plug described in embodiment is identical, will not be described in detail herein.
