Description

A kind of SFP optical transceiver module

Technical field

The utility model relates to SFP optical transceiver module encapsulation field, particularly a kind of SFP optical transceiver module that can easy release.

Background technology

At present, SFP optical transceiver module (SFP), the release mechanism design that its encapsulation is generally adopted is at SFP module head, rely on the wedge shape part to release, back down the release of cage snap close with the inclined-plane, this kind mechanism is owing to be to be provided with spring in narrow SFP head space, the wedge shape part, parts such as pull bar, complex structure, and work the time will produce bigger friction force, the user often will just can finish release with bigger strength and take out module, separate lock assembly rapid wear consumption, functional lifetime is short, reliability is low, and product head outward appearance is too fat to move not attractive in appearance.

The utility model content

The purpose of this utility model provide a kind of fast, convenient plug, dependable performance, usability, maintainability is good, outward appearance is neatly unified, the SFP optical transceiver module that is easy to release.

A kind of SFP optical transceiver module of the present utility model is achieved by following technical proposals:

A kind of SFP optical transceiver module, comprise box body 1, be enclosed within the panel beating shell spare 2 in the box body outside, be separately positioned on the electricity mouth 4 and the light mouth 5 at box body two ends, and optical device location structure and module release mechanism, described module release mechanism comprises H shape shell fragment 9 at panel beating shell spare 2 upper surfaces, is positioned over the boss 3 of separating locking plate 11 and box body 1 upper surface between box body 1 and the panel beating shell spare 2; One C shape drum parts 10 are arranged at the bottom of described H shape shell fragment 9.

Describedly separate the head that locking plate 11 stretches in the box body 1 one opening is arranged, the inward flange of this opening extends one section inclined plane part 14 to side-lower; When locking, in the opening of C shape drum parts 10 on falling into release sheet 11 of H shape shell fragment 9 bottoms of panel beating shell spare 2, the boss 3 of box body 1 upper surface passes to be separated the opening on the locking plate 11 and extends to outside the upper surface of panel beating shell spare 2, stretch in the hole clipping on the switch cage elastic tongue piece, thereby make module be locked in the switch cage.

When release, outwards spur release sheet 11, when the bottom C shape drum parts 10 of separating H shape shell fragment 9 on inward flange below inclined plane part 14 and the panel beating shell spare 2 of opening of locking plate 11 contact, the contact position is streamlined contact, C shape drum parts 10 make progress on the sheet dignity of separating locking plate 11 along inclined plane part 14, at this moment, H shape shell fragment 9 forms elastic deformation, jack-up and promote the boss 3 that switch cage elastic tongue piece hole clipping breaks away from box body 1 upper surface upwards, thereby remove the locking of cage to module, after module was extracted cage, H shape shell fragment 9 recovered deformation.

As a kind of improvement, also comprise being fixed on the annular pull rod 12 of separating locking plate 11 outsides, and be enclosed within the sleeve pipe 13 on the pull bar 12.Finger stretches in the annular pull rod 12, is more convenient for pulling the moving locking plate 11 of separating.

There is reed panel beating shell spare 2 both sides, and its bottom surface also is provided with two reeds, and different with 3 fixations of boss of surface of shell, it plays ESD and heat transfer process.

A kind of SFP optical transceiver module of the present utility model compared with prior art has following good effect:

A kind of SFP optical transceiver module contour structures of the present utility model reaches the SFP protocol requirement fully, physical dimension is little, the user is under identical space, can arrange more SFP module, simplified release mechanism, significantly improved unlocking function stability and life-span, product is compact succinct, and its usability, reliability, security, productibility, maintainability are good.

Description of drawings

The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a module release mechanism sectional view of the present utility model.

Embodiment

Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

A kind of SFP optical transceiver module of present embodiment, as shown in Figure 1, comprise box body 1, be enclosed within the panel beating shell spare 2 in the box body outside, be separately positioned on the electricity mouthfuls 4 and the light mouth 5 at box body two ends, electricity mouthful constitutes by being arranged on the circuit board that its rear end in the box body is processed with 20 Copper Foil bands; The light mouth is made up of cavity and interior optical device and location, compressing structure thereof, after optical device is by box body arc fluting location, briquetting is pressed in the optical device same area, the plasticity of having utilized panel beating shell spare to have is pressed on the briquetting by outer panel beating shell spare, owing to can guarantee that the contact of sun adjuster spare is fixed again, sun adjuster spare plays effective thermolysis, also improve the productive capacity finish scantling fault-tolerant ability and module, and this structure avoids the use trip bolt fully, also be easy to produce assembling.

The module release mechanism comprises H shape shell fragment 9 at panel beating shell spare 2 upper surfaces, is positioned over the boss 3 of separating locking plate 11 and box body 1 upper surface between box body 1 and the panel beating shell spare 2; One C shape drum parts 10 are arranged at the bottom of described H shape shell fragment 9; Comprise also being fixed on the annular pull rod 12 of separating locking plate 11 outsides, and be enclosed within the sleeve pipe 13 on the pull bar 12 that annular pull rod 12 can be rotated up and down around separating locking plate 11 heads.

Describedly separate the head that locking plate 11 stretches in the box body 1 one opening is arranged, the inward flange of this opening extends one section inclined plane part 14 to side-lower; In the switch cage during locking, the boss 3 of box body 1 upper surface passes to be separated the opening on the locking plate 11 and extends to outside the upper surface of panel beating shell spare 2, stretches in the hole clipping on the switch cage elastic tongue piece; In the opening of C shape drum parts 10 on falling into release sheet 11 of H shape shell fragment 9 bottoms of panel beating shell spare 2, annular pull rod 12 turns to foot, is affixed on box body 1 surface.

When release, outwards spur release sheet 11 by annular pull rod 12, driving box body 1 skids off from panel beating shell spare 2, when the bottom C shape drum parts 10 of H shape shell fragment 9 on the inward flange below inclined plane part 14 of separating locking plate 11 openings and the panel beating shell spare 2 contact, the contact position is streamlined contact, C shape drum parts 10 make progress on the sheet dignity of separating locking plate 11 along inclined plane part 14, at this moment, H shape shell fragment forms elastic deformation, jack-up and promote the boss 3 that switch cage elastic tongue piece hole clipping breaks away from box body 1 upper surface upwards, thereby remove the locking of cage to module, after module was extracted cage, H shape shell fragment 9 recovered deformation.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
