Description

A kind of QSFP interface module structure

[technical field]

The utility model belongs to the photoelectric communication transmission technique field.

[background technology]

For the High Speed I/O in network, storage and the telecommunication apparatus application is connected, the advantage that can plug the I/O interface is very obvious.At present, comprise that the little encapsulation hot plug product line of single port and single stack high-density multi-port SFP (Small Form-factor Pluggables) screening cage was ripe already, commercial Application is very extensive.High-speed signal connector and electromagnetic interference shield cage have all been comprised on their mainboard.Along with the day by day raising of market to function and message transmission rate requirement.Can plug the demand of solution in order to satisfy market to more highdensity high speed, the SPF interface of quad (QSFP, Quad Small Form-factor Pluggable Plus) arises at the historic moment.The plugged interface transfer rate of this 4 passages has reached 40Gbps.Ripe gordian technique all has been applied in this design among a lot of XFP.

QSFP can be used as a kind of optical fiber solution, and speed and density all are better than 4 channel C X4 interfaces.Owing to can be under the identical port volume of XFP support the data transmission of four passages with the speed of every path 10 Gbps, so the density of QSFP can reach 4 times of the XFP product, 3 times of SFP+ product.Having 4 passages and the density QSFP interface higher than CX4 is adopted by the InfiniBand standard.

Owing to require such QSFP interface module plug flexibly, require connection status stable simultaneously, therefore in this generic module, all be provided with mechanical latching device.Have the latching device that is arranged on the QSFP interface module now, mainly adopt the tactic pattern of lever or hook or slide wedge, No. 200520034680.5 patents of China " modular device " promptly disclose a kind of similar structures; And the disclosed data of Chinese 200620096891-6 patent " extraction mechanism of triping on the SFP module " is that prior art is improved, at built-in stage clip below the sled sheet that blocks the cage effect, can trip to extract at the card cage like this and rebound after operation is finished, make easy to operate, but its structure phase shortage is to complexity.Traditional SFP module latching device design complexity is not easy to operation, when cubicle interface density is big performance particularly outstanding, it is little that cable goes out space of lines, also arranges to cable and bring puzzlement.

[utility model content]

In view of this, a kind of plug is convenient, constitutionally stable QSFP interface module structure in order to provide for the technical problems to be solved in the utility model:

A kind of QSFP interface module structure, comprise module housing and be installed on the interior pcb board of shell, be equipped with on the shell the latching device of module snap close on external interface, described latching device comprise a unlock piece and be installed on unlock piece and shell between back-moving spring, the unlock piece leading portion is two locking plates of separating that are positioned at the shell two sides, two separate locking plate end arranged outside the release boss, and the release boss has the dip plane, connects a handle in the unlock piece rear end.

As the improvement to such scheme, described unlock piece is a metalwork, be provided with in the shell both sides hold separate locking plate groove.Simultaneously, the back-moving spring that is adopted is a torsion spring, and its two ends are buckled in outer casing inner wall, and the centre is provided with two spiral center pits, and the spiral center pit is placed on the fixed pin default on the unlock piece inwall.And described handle is a soft plastic sheet, is placed on the default hangers in unlock piece rear end.

As further improvement of these options, described shell upper casing, the mutual buckle of lower casing, between upper casing and the lower casing by rivet and be arranged at upper casing, lower casing buckle position fixes.

As the further improvement to such scheme, described buckle position comprises and is arranged at Ka Tai and the draw-in groove that upper casing, lower case side wall mate mutually that the depression direction of the bearing of trend of Ka Tai and draw-in groove is consistent with the outer cover length direction.

Compared with prior art, the utility model structure is more succinct, and plug is also convenient, can realize quick-speed plug, and dependable performance is stable, and is practical.And this structure outward appearance can be accomplished cleaner and tidier, and the inner space utilization factor is higher, though from design, or produce and all have good advance in the operation.

[embodiment]

Understand for the ease of this area engineering technical personnel, will and be described in detail the utility model in conjunction with the accompanying drawings by specific embodiments below.

Shown in accompanying

drawing

1,2,4.The disclosed QSFP interface module of this programme structure comprises the shell of being made up of upper casing 12, lower casing 13 1 and is installed on pcb board 2 in the shell 1, is installed on the latching device 3 of being convenient to the whole module of quick-speed plug on the shell 1.

Wherein, upper casing 12 and lower casing 13 mutual buckles, and between upper casing 12 and the lower casing 13 by rivet 4 and be arranged at upper casing 12, lower casing 13 buckle positions 14 fix.This buckle position 14 comprises and is arranged at card platform 141 and the draw-in groove 142 that upper casing 12, lower casing 13 sidewalls mate mutually that the bearing of trend of card platform 141 and the depression direction of draw-in groove 142 are consistent with shell 1 length direction.When needs with upper casing 12, when lower casing 13 is combined to form shell 1, will block platform 141 and be stuck in the draw-in groove 142, upper casing 12, lower casing 13 front ends are fixed, and then the rear end are fixed by rivet 4, form constitutionally stable shell thus.

In this programme, the latching device 3 that is adopted comprise a unlock piece 31 and be installed on unlock piece 31 and shell 1 between back-moving spring 32, unlock piece 31 leading portions be two be positioned at shell 1 two sides separate locking plate 311, two separate locking plate 311 end arranged outside release boss 312, the release boss has dip plane 313 (in detail as shown in Figure 3), connects a handle 33 in unlock piece 31 rear ends.Unlock piece 31 in the present embodiment is a metalwork, and is complete and be convenient to the smooth and easy of plug in order to keep monnolithic case, be provided with in shell 1 both sides hold separate locking plate 311 groove 11.The back-moving spring 32 that is adopted is a torsion spring, and its two ends are buckled in shell 1 inwall, and the centre is provided with two spiral center pits 321, and spiral center pit 321 is placed on the fixed pin 314 default on unlock piece 31 inwalls.The handle 33 that is adopted is a soft plastic sheet, is placed on the default hangers 315 in unlock piece 31 rear ends.

When this module being assigned in the corresponding jack of connector, default screens is stuck in two and separates locking plate 311 outer wall boss 312 places in the connector plug jack, when needs are extracted this module, only need outwards pulling handle 33, handle 33 pulling unlock pieces 31 outwards move, the boss 312 and the dip plane 313 of separating simultaneously on the locking plate 311 eject the screens in the connector plug jack, thereby module can be extracted smoothly.

The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
