Embodiment

Please refer to shown in Fig. 1 to Fig. 7, it has demonstrated the concrete structure of the preferred embodiment of the utility model.A kind of SFP module interface include SFP module bodies 10, for delivery of the optical cable 20 of light signal and for card cage coordinate buckle structure 30, this optical cable 20 is connected in SFP module bodies 10, this buckle structure 30 is located at the tail end of SFP module bodies 10.Wherein:

As shown in Figure 5, described SFP module bodies 10 is made up of housing 11 and the circuit board 12 being contained in housing 11.This housing 11 is assembled and is formed by upper shell 111 and lower house 112.Lower house 112 is in the form of slot, is accommodated with circuit board 12 in cell body.This upper shell 111 and lower house 112 use screw connecting mode fixing circuit boards 12.In addition, upper shell 111 tail ends of described SFP module bodies 10 are provided with a storage tank 13, are arranged with the longitudinal chute 14 forming by storage tank 13 bottoms downwards, on the mating surface 17 coordinating with card cage in SFP module bodies 10, have the lock dog 15 that hooks card cage, it coordinates buckle structure 30 fast SFP module bodies 10 to be lock onto to card cage and quick release exits card cage.

As shown in Fig. 2-7, described buckle structure 30 comprises that a sliding shoe 31, one are connected in the slide bar 32 of sliding shoe 31 front ends, are connected to the back-moving spring 33 of sliding shoe 31 and SFP module bodies 10 and are connected to the handle 34 of sliding shoe 31 tail ends.The head end of this slide bar 32 is provided with a jack-up projection 321; The sliding shoe 31 of this buckle structure 30 is installed on storage tank 13 movably, and slide bar 32 mates with longitudinal chute 14.As shown in Figure 4, when slide bar 32 is placed in longitudinal chute 14, the height that jack-up projection 321 stretches out mating surface 17 is greater than the height of lock dog 15 outstanding mating surfaces 17, and the difference in height of the two is H.In the present embodiment, the rear side end of this jack-up projection 321 is inclined-plane 322, and the front side end of lock dog 15 is also inclined-plane 151, can upwards be out of shape by a guiding card cage.As shown in Figure 5, handle 34 comprises first ring 341 and the second ring 342, and this first ring 341 is positioned at optical cable 20 below (see figure 1)s by top through optical cable 20, the second rings 342.By this, when handle 34 rearward pulls, drive sliding shoe 31 and slide bar 32 entirety to slide backward, in the time that jack-up projection 321 aligns with lock dog 15, by jack-up projection 321, the snap-on sheet of card cage is upwards pushed up, remove lock dog 15 and block spacing between cage, therefore can fast SFP module bodies 10 be extracted.

Particularly, the left and right sides of described sliding shoe 31 is provided with guiding sliding part 311, the upper shell 111 tail end both sides of the SFP module bodies 10 of correspondence are respectively equipped with projection 16, and the opposing sidewalls of this two projection 16 is concaved with guiding groove 161, and this guiding sliding part 311 coordinates with guiding groove 161.In addition, be also provided with stop section 162 at the tail end of guiding sliding part 311, avoid sliding shoe 31 to exit excessively, can not deviate from guiding groove 161, this fitment stability is high, and profile is unified clean and tidy.

In order to facilitate the installation of back-moving spring 33, the bottom surface of described storage tank 13 is longitudinally provided with two the first half grooves 131, the bottom surface of the sliding shoe 31 of correspondence is longitudinally provided with two the second half grooves 312, two the first half grooves 131 and two the second half grooves 312 enclose and form spring storage tank 13, and described back-moving spring 33 is installed in this spring storage tank 13.

Principle of work of the present utility model is as follows:

Under state of nature, the back-moving spring 33 in SFP module bodies 10 is positioned at spring storage tank 13, in natural elongation state.In the time that it is pushed to card cage, lock dog 15 fastens with the snap-on sheet on card cage, completes SFP module bodies 10 and blocks coordinating accurately and reliably between cage.In the time SFP module bodies 10 need being extracted, pull back the handle 34 of the structure structure of lock, handle 34 pulls sliding shoe 31 and slide bar 32 to shift out backward, compression reseting spring 33, moved backward by jack-up projection 321 thereupon, the height that jack-up projection 321 stretches out mating surface 17 is greater than the height of lock dog 15 outstanding mating surfaces 17, thereby jack-up projection 321 can back down by its inclined-plane 322 fastening of card cage and SFP module bodies 10, whole SFP module bodies 10 is extracted from card cage, after loosing one's grip, realize and automatically reseting by the restoring force of back-moving spring 33.

In sum, design focal point of the present utility model is, directly in slide bar 32 ends of latching device, jack-up projection 321 is set, the height that only need to make jack-up projection 321 stretch out mating surface 17 is greater than the height of lock dog 15 outstanding mating surfaces 17, in the time that handle 34 pulls back, make release SFP module bodies 10 easily.This latching device is simplified, and back-moving spring 33 coordinates ingenious, can also automatically restore to the original state after drawing top release, operates simple and easy, good stability, and profile is clean and tidy, and assembling easily.

The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
