Description
Technical field
The utility model relates to a kind of optic module web member interface, particularly a kind of can the optical signal interface device (be called for short SFP) that uses of hot plug.
Background technology
Along with market is to the raising day by day of function and data transmission rates demands.In order to meet the demand of market to more highdensity High-Speed Passenger plug solution, the QSPF interface (QSFP, Quad SmallForm-factorPluggable Plus) of quad arises at the historic moment.The pluggable interface transfer rate of this 4 passages reaches 40Gbps.Gordian technique ripe in a lot of XFP has all been applied in this design.
Existing SFP interface device is roughly formed by upper cover, lower cover, PCB, optical fiber cable and draw ring, and PCB is placed between upper cover and lower cover, and its one end connects with optical module connector, and the other end connects with optical fiber.Upper cover or under cover and be provided with snap close office, described tab nose connects with snap close office, during use, snap close office is inserted in optical module connector, makes upper cover, lower cover and PCB be fixed in optical module connector; The not used time, pull out described draw ring, the front end of draw ring impels snap close office to unlock, thus locking machine is correlated same upper cover, lower cover extracts together with PCB from optical module connector.
This structure exists following not enough:
1) due to snap close office complex structure, thus, its manufacture craft difficulty is large, and manufacturing cost is higher.
2) because snap close office complex structure causes efficiency of assembling low.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of cost of manufacture is low, production efficiency is high and the four-way SFP interface of good reliability.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Four-way SFP interface of the present utility model, comprise upper cover, lower cover and the PCB be fixed between upper cover and lower cover, the fixed block of fixed fiber lead-in wire is provided with at the tail end of PCB, under cover the movable spring slice being also provided with and this interface can being pushed optical module connector or pull out from optical module connector, described movable spring slice is made by stainless steel material, the biside plate of its tail end is provided with the through hole laying needle shaft, the main body of described needle shaft is inserted in the plastic body of the tab nose made by plastic material by burying forming plastic cement technique in mould, the two ends of described needle shaft are inserted in described through hole.
Be provided with in the front end of described movable spring slice and there is elasticity and the contact that can insert in optical module connector.
Described needle shaft is made by stainless steel material.
The optical fiber cable be connected with fixed block end is also provided with the cable protective element be made up of soft plastic which is provided with interrupted through hole extended along optical fiber cable length direction.
Movable spring slice tail end two side on four-way SFP interface arranges through hole to the utility model, burying forming plastic cement technique (Insertmolding) in mould will be adopted again the tab nose on four-way SFP interface and the needle shaft one-shot forming made by stainless steel material to be structure as a whole, in through hole described in again the two ends of this needle shaft being inserted, thus, make four-way SFP interface of the present utility model without the need to arranging as snap close office of the prior art.The utility model structure is simple, and cost of manufacture is low, efficiency of assembling is high.In addition, due to draw ring, between needle shaft and movable spring slice, Stability Analysis of Structures is firm, and therefore, its serviceable life is corresponding growth also.
