Detailed description of the invention
The enforcement of mother daughter board connector assembly is such as shown in Fig. 1 ~ 5: the backboard socket being arranged on corresponding backboard when including the daughter board plug and the use that are arranged on corresponding daughter board when using.Daughter board plug includes shell body 6, and shell body 6 has locking shell 7 by the first elastic component floating assembly along the longitudinal direction, and the first elastic component is spring.In locking shell 7, guiding movement is provided with integrally-built male component housing 8 along the longitudinal direction, male component housing is insulator structure, male component housing is provided with two rows Plug contact unit, it is the Plug contact unit 1 of inserted terminal that every socket head contact unit all includes spaced apart three front ends in left-right direction, each Plug contact unit 1 is floated along the longitudinal direction by the second elastic component and is arranged in male component housing, second elastic component is spring, and in the present invention, Plug contact unit 1 is optical fiber contact unit.Being provided with on male component housing and play, for the locking with socket, the locked groove that pawl coordinates, locking can be played pawl and be limited in locked groove thus realizing locking by locking shell 7.Shell body is provided with the gathering sill that guide direction extends in left-right direction, in gathering sill, guiding movement is equipped with shell body block 4 in left-right direction, shell body block 4 is metalwork, and between the left side cell wall of shell body block 4 and gathering sill, top is provided with the back-moving spring 5 that two front and back are arranged.The upper end of gathering sill is provided with cover plate 11, the right front ends of gathering sill is provided with breach, shell body block is provided with the bearing member 3 passed by breach, bearing member includes the montant extended along the longitudinal direction and the cross bar extended in left-right direction, cross bar is connected with shell body block, and the front end of montant is provided with for being made shell body block towards the block load portion 2 moved left by Socket casing pushing tow.Male component housing is provided with three spaced part case blocks 9 in left-right direction, corresponding shell body block has two for coordinating to limit the block projection 10 that male component housing moves backwards with the two of right side part case block blocks, when shell body block is towards when moving left, block projection 10 can move in the gap 20 between connected two part case blocks, thus getting out of the way part case block, now male component housing is no longer by shell body block block, and male component housing can move by opposite shell body backwards.
Backboard socket includes Socket casing 14, female component housing 15 and the socket contact unit 16 being correspondingly arranged with Plug contact unit, female component housing is all-in-one-piece insulator structure, female component housing is provided with the locking bullet pawl 13 for coordinating with the locked groove on male component housing and locking shell, wherein locking bullet pawl belongs to prior art with the matching relationship of locked groove and locking shell, is no longer discussed in detail at this.The pushing tow inclined-plane in the block load portion being provided with on Socket casing on pushing tow shell body block.In the present embodiment, Plug contact unit is male, and socket contact unit is female.
During use, backboard socket is installed on backboard, daughter board plug is installed on daughter board, advance daughter board, daughter board moves towards backboard socket together with male component housing with locking shell, locking shell be locked bullet pawl pushing tow then move, after locking bullet pawl is stuck in locked groove, by the first elastic component effect, locking shell moves forward and locking is played pawl and is limited in locked groove, it is achieved the locking of Plug contact unit and socket contact unit.When daughter board continues to push ahead, meeting pushing tow block load portion, pushing tow inclined-plane on Socket casing, make shell body block transverse shifting, after in the gap that the block projection on shell body block moves between adjacent two part case blocks, shell body block no longer stops male component housing, now male component housing just can be moved rearwards by with locking shell, thus achieve while contact is reliably connected, daughter board has certain activity space, and the rigging position for daughter board and backboard provides bigger adjustment space.
Adopt integrally-built female component housing, male component housing, synchronize locking during plug or unlock, making plug more smooth and easy, steady.Owing to elasticity need not be utilized to realize the block to male component housing and unblock, therefore shell body block can be made up of metalwork, intensity is big, it is important that block is protruding and can have very big load-carrying surface between part case block so that shell body is more reliable to the block between part case block.
In other embodiments of the invention: block load portion can also be arranged at the left side of shell block, now part case block can be unlocked by shell body block by moving right；The number of part case block can also select as required, such as one, two or other number, now the block projection number on shell body block can also adaptive change；Shell body block can also be nonmetal parts, such as plastics；Bearing member can also be without setting, such as block bearing position is on the side of shell body block, the side of the direct pushing tow shell body block in pushing tow inclined-plane on Socket casing；When not adopting the locking mechanism of locking shell formula between daughter board plug and backboard socket, such as when adopting between daughter board plug and backboard socket by frictional force direct-plug structure, locking shell can not set, and now the first elastic component can be arranged directly between shell body and male component housing；First elastic component, the second elastic component may not be spring, can produce rubber or other elastomer of elastic deformation for example in the longitudinal direction；Daughter board plug and backboard socket can also is that electric connector；Plug contact unit can also is that female, and now socket contact unit is male.
The enforcement of daughter board plug is such as shown in Fig. 1 ~ 3: the concrete structure of daughter board plug is identical with the daughter board plug described in above-mentioned each mother daughter board connector Assemblies Example, is not described in detail in this.
