Description

A kind of laminated type tripper and RJ45 electricity mouth SFP module thereof

Technical field

The utility model relates to optical interconnection module, particularly relates to a kind of laminated type tripper and RJ45 electricity mouth SFP module thereof.

Background technology

In data communication and telecom communication circuit, widely apply SFP module, i.e. small plug-type light emitting/telecommunication transmitting-receiving connector (Small Form-Factor Pluggable, abbreviation SFP).It is for providing the function of bidirectional data transfers in optical communication system, main application fields comprises SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy) add-drop multiplexer, light edge devices and MSPP(modular software programmable processor, modular software processor able to programme) and exchange system.

MSA(MultiSource Agreement, multi-source agreement) or SFF-8432 agreement in define the physical construction of SFP optical module.Be connected for dismantled and assembled between SPF optical module with switch cage, operationally SFP optical module be inserted into the switch cage 203 interior (as Fig. 2) with corresponding SFP interface.SFP optical module is locked by its release mechanism carried insertion realized between switch cage 203 or is unlocked and extracts.

But because its connector of RJ45 electricity mouth module 100(is as Fig. 1) IEC-60603 standard criterion need be met, so this generic module head can be less for the leeway of design, release mechanism form is single.At present, in industry, electric mouth SFP unlocking manner is almost: user is by rotating draw ring 200, cam feature 201 on draw ring promotes push rod inclined-plane 202 and moves to cage direction, the lockhole 204 of cage is upspring, module is locked a little 205 to depart from cage lockhole 204, reach optical module and exit cage 203 object.

Meanwhile, due to above structural limitations, make current line in the industry RJ45 electricity mouth module all have following problem:

1, due to RJ45 connector 100 and the setting of release mechanism, shoulder height 108 and lower shoulder height 107 in module is made more than the restriction of 2mm size maximum in MSA and SFF-8432, to cause compatibility issue;

Namely RJ45 electricity mouth module is on high port density switch, easily occurs the situation that upper and lower module is interfered, causes and cannot carry out high density plug, the port resource of waste switch preciousness.

2, in actual use, repeat plug reliability low, easily occur locking the problem that maybe cannot unlock.

3, release mechanism cannot automatically reset, and user operation is experienced low.

4, PCB can be little with fabric swatch area, cannot meet the layout requirements that speed is greater than the PHY chip of 1G.

5, in current industry, electric mouth module mainly uses the die casting shell of kirsite, and processing technology is complicated, and it directly causes following technological problems:

1) problem of dimensional stability

Kirsite, after die casting, also has the operations such as blanking, deburring, sandblasting and plating; What have in these operations at present needs manual operations, comparatively large on the impact of dimensional stability, causes the dimensional uniformity of SFP package module lower, also indirectly causes the problems such as unblock.

2) manufacturing cost is high

Current kirsite housing is lower to last assembling yield rate from die casting, is approximately about 85%.

3) problem of environmental pollution.

Current shell almost all adopts zinc alloy diecasting, must use electroplating technology, and the waste liquid produced in electroplating technology, if deal with improperly, very easily cause environmental pollution.

In a word, existing unlocking manner and shell Shortcomings, directly hinder the application of mouth SFP module on high port density and high rate communication circuit of RJ45 electricity, lacks a kind of unlocking structure of thoroughly addressing these problems and shell.
