Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
Referring to Fig. 1-Fig. 5, a kind of pre-terminated module, including shell 1 is provided with two rows groove 11 on the shell 1,
Often row has 3 grooves, two rows of grooves 11 symmetrical.One end of the groove 11 is to match vessel with crystal head
110, cable interface inner core is provided in the groove 11.There are one dust covers for the also each clamping in the top and bottom of the shell 1
12。
The inner core include pedestal 2, the pedestal 2 setting be provided with PCB on 11 bottom of the groove, the pedestal 2
Plate 3 is provided with clamping seat 31 and routing lid 32 on the pcb board 3.
Further include cover board 4, the cover board 4 is rotatably connected on the top of the groove 11.Each groove top is both provided with
One piece of cover board 4.
The both sides of the shell 1 are provided with horizontal concrete chute 13 and longitudinal chute 14, are slidably connected in the horizontal concrete chute 13
There is pull rod 5, the upper and lower ends in 5 centre position of the pull rod are groove 51,52, and the cross-sectional shape of groove 51,52 is triangle.
Mandril 61,62 is provided in the longitudinal chute 14.The top and bottom of the longitudinal chute 14 are each provided with one
Root mandril 61,62, the mandril 61,62 include the extension 611,621 of a transverse direction, are arranged on the extension 611,621
There are convex block 612,622, one end of spring 7 to be sleeved on the convex block 612,622, the other end of the spring 7 is inserted into the shell 1
In the molding card slot in side 16.Under the action of the spring, mandril 61,62 is close to one end on the outside of longitudinal chute and is inserted into distributing frame
On 100 in matched groove 101, the connection between the utility model and distributing frame is realized.
Be rotatably connected on the mandril 61,62 with 51 matched idler wheel 613,623 of the groove, be located at the longitudinal direction
