Specific embodiment
For convenient for those skilled in the art understand that the utility model technology contents, with reference to the accompanying drawing to the utility model
Content is further illustrated.
The pin wasting of resources of optical module electrical interface is encapsulated in order to solve Video client using routine SFP, and
Contour structures need the problem of customizing；The utility model designs optical module electrical interface and uses contact pin form, is directly welded at board
Mainboard on, stability ratio SFP encapsulate optical module it is more preferable.The utility model designs optical module and uses FC optical interface, compared to normal
It is more stable to advise SFP encapsulation optical module optical interface.The utility model design optical module does not need shell, and contour structures can be according to client
Board customization, convenient for the fabric swatch demand of different situations.
The specific electrical interface definition using 1 × 4 contact pin form as shown in Figure 1, eliminates Video optical mode
The unwanted state of a control pin of block；The utility model arranges needle size as shown in the main view of Fig. 2, the specific rule of the row's of giving needle
Lattice, arranging needle length in the present embodiment is 10mm, head 2.1mm, tail portion 2.9mm, specifically as shown in the right view of Fig. 3；Fig. 4
For top view, the row's of giving needle spacing is 1.27mm, and row's needle spacing in the present embodiment is set as 1.27mm, has both guaranteed that welding can
Operability, and the overall dimensions of module can be reduced.
As illustrated in figs. 5-7 be optical module one of structure size figure, Fig. 5 is main view, give FC optical device with
The layout drawing of pcb plate, the row's needle and positioning column that are directly welded on pcb board；As shown in fig. 7, two positioning columns are set to PCB
Plate is close to FC optical device side, and the optical device both sides that are placed in, and gives the size and its shape of pcb board, is only here
