Description

Technical Field

[0001] The utility model relates to the field of SFP modules, in particular to a plug-in SFP module. Background Art

[0002] The pluggable SFP module, or Small Form Factor Pluggable (SFP), is a high-speed optoelectronic device used for data communications. An upgraded version of the GBIC optical module, it is compact, only about half the size of a GBIC, and can accommodate more than double the number of ports on the same panel. It supports hot swapping, facilitating module replacement without shutting down the system, improving system flexibility and availability. SFP optical modules support a variety of data transmission rates, such as 1Gbps, 2.5Gbps, 4Gbps, and 10Gbps, and feature a variety of interface types and transmission distances. They can connect to various network devices and achieve high-speed data transmission. They are widely used in data centers, metropolitan area networks, telecommunications networks, industrial control, video surveillance, and other fields.

[0003] In the prior art, plug-in SFP modules are usually plugged into the switch SFP slot in the form of an elastic locking tongue buckle to achieve snap-on fixation. Due to the lack of rigid external fixing measures, the fixing effect of the plug-in SFP module after plugging is poor, and the connection is not firm enough, which makes the SFP module easy to loosen between the device during use, and may fall off due to external factors such as accidental touch during use, thereby affecting the normal use of the plug-in SFP module and the device. Although some plug-in SFP modules currently have locking and fixing measures, they are more cumbersome to operate and not convenient to use. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 6 As shown, a plug-in SFP module includes an SFP module body 1, which is plugged into the SFP slot 2 of the switch. The SFP module body 1 is also fixedly connected to the SFP slot 2 of the switch through a locking and fixing mechanism 3 at the top of the front end, and the locking and fixing mechanism 3 includes a mechanism housing 6, a trapezoidal block 10, a threaded short rod 13, a movable plate 16, a limit rod 17, a compression spring 18 and a wedge block 19. The mechanism housing 6 is fixedly connected to the top of the front end of the SFP module body 1, and the trapezoidal block 10 is movably connected to the mechanism housing 6 through the sliding bar 11 on the upper and lower walls. The threaded short rod 13 is movably connected to the trapezoidal block 10 through the rotating block 14 at the rear end, and the two movable plates 16 are movably connected to the mechanism housing 6 through the limit rods 17 on the outer wall respectively. The compression spring 18 is sleeved on the outer wall of the limit rod 17, and the wedge block 19 is fixedly connected to the inner wall of the movable plate 16.

[0023] like Figure 2 As shown, side panels 4 are fixedly mounted on the top of the left and right sides of the front end of the switch SFP slot 2, and a set of symmetrical limiting holes 5 are opened on the side walls of the side panels 4. The limiting holes 5 opened on the side panels 4 are used to cooperate with the locking and fixing mechanism 3.

[0024] like Figure 3 and Figure 4 As shown, the mechanism housing 6 is fixedly mounted on the front top of the SFP module body 1, and the inner top and bottom surfaces of the mechanism housing 6 are respectively provided with slide grooves 7, which are used to cooperate with the slide bar 11 to achieve a sliding operation. A group of symmetrical through holes 8 corresponding to the limit holes 5 are respectively provided on the left and right side walls of the mechanism housing 6. The through holes 8 can ensure that the limit rod 17 can be moved out of the mechanism housing 6 and moved to the mechanism housing 6, and a screw hole 9 is further provided on the front wall of the mechanism housing 6. The screw hole 9 is used to cooperate with the threaded short rod 13 to achieve a threaded rotation operation.

[0025] like Figure 5 and Figure 6 As shown, the threaded short rod 13 is threadedly connected to the screw hole 9, and a rotating block 14 is fixedly installed on the rear end wall of the threaded short rod 13, and a knob 15 is fixedly installed on the front end wall of the threaded short rod 13. The threaded short rod 13 can be rotated by the knob 15 to realize the threaded rotation operation in the screw hole 9, and the threaded short rod 13 will drive the rotating block 14 to rotate and move;

[0026] like Figure 5 and Figure 6As shown, the trapezoidal block 10 is in the shape of an isosceles trapezoid, and a slide bar 11 is fixedly mounted on the top and bottom surfaces of the trapezoidal block 10, respectively. The slide bar 11 is movably mounted in the slide groove 7. A convex groove 12 is further provided on the front end wall of the trapezoidal block 10, and a rotating block 14 is movably mounted in the convex groove 12. When the rotating block 14 rotates, it pushes the trapezoidal block 10 to move rearward in the mechanism housing 6, and the slide bar 11 slides in the slide groove 7.

[0027] like Figure 5 and Figure 6 As shown, the movable plate 16 is provided with a group of symmetrical limit rods 17, and a group of symmetrical limit rods 17 are fixedly installed on the outer wall of the movable plate 16. The limit rods 17 pass through the through hole 8 and are inserted into the limit hole 5. The outside of the limit rods 17 is also covered with a compression spring 18, which is fixed between the movable plate 16 and the inner wall of the mechanism housing 6. A wedge block 19 is also fixedly installed on the inner wall of the movable plate 16. Under the movement of the trapezoidal block 10, the wedge blocks 19 installed on the opposite walls of the symmetrical movable plates 16 will be squeezed by the trapezoidal block 10. When the wedge blocks 19 move outward, they will push the movable plate 16, and the movable plate 16 will force the compression spring 18 to retract until the limit rods 17 pass through the through hole 8 and enter the limit hole 5, thereby achieving the purpose of quickly limiting and locking the SFP module body 1 in the switch SFP slot 2 for use, and preventing the SFP module body 1 from loosening or falling off due to external factors during use.

[0028] It should be noted that the present invention is a plug-in SFP module. After the SFP module body 1 is inserted into the SFP slot 2 of the switch, the knob 15 located on the front end wall of the mechanism housing 6 installed at the top front end of the SFP module body 1 is rotated. The knob 15 will drive the threaded short rod 13 to realize the threaded rotation operation in the screw hole 9 opened on the front end wall of the mechanism housing 6. When the knob 15 is continuously rotated, the knob 15 will move into the mechanism housing 6 and drive the rotating block 14 installed at the rear end to rotate in the convex groove 12 opened on the front end wall of the trapezoidal block 10, and the trapezoidal block 10 is synchronously pushed to move backward by the rotating block 14. When the trapezoidal block 10 moves, the slide bars 11 installed on the top and bottom surfaces will slide in the slide grooves 7 opened on the top and bottom surfaces inside the mechanism housing 6. At the same time, the trapezoidal block 10, which is in the shape of an isosceles trapezoid, will squeeze the inclined parts of the wedge blocks 19 installed on the opposite walls of the left and right movable plates 16 through the inclined parts of the two side walls. The wedge blocks 19 on both sides will move in opposite directions after being squeezed by the trapezoidal block 10, and will push the movable plate 16 to move outward during the movement, and force the compression spring 18 installed between the movable plate 16 and the inner wall of the mechanism housing 6 to retract, while the compression spring 18 installed on the outer wall of the movable plate 16 will retract. The limiting rod 17 will also pass through the corresponding through holes 8 opened on the two side walls of the mechanism housing 6 until the limiting rod 17 passes through the through holes 8 and is inserted into the limiting holes 5 opened on the side walls of the extended side panels 4 installed on the top of the front sides of the switch SFP slot 2, and the knob 15 can no longer be rotated. Therefore, after the SFP module body 1 is plugged into the switch SFP slot 2, the SFP module body 1 can be quickly limited and locked and fixed in the switch SFP slot 2 for use, which not only improves the fixing effect of the SFP module body 1 after plugging, but also avoids the SFP module body 1 from being damaged by external factors during use. There is a problem of looseness or falling off, and the connection stability of the SFP module body 1 is ensured by a rigid connection, thereby ensuring the normal use of the SFP module body 1 and the equipment. Finally, when the SFP module body 1 needs to be pulled out from the switch SFP slot 2, the knob 15 is rotated in the opposite direction to move the trapezoidal block 10 forward, and no longer squeezes the wedge block 19, so that the movable plate 16 moves inward under the elastic recovery and stretching force of the compression spring 18, and drives the limiting rod 17 to move out of the limiting hole 5, through the through hole 8 and into the mechanism housing 6, and the SFP module body 1 can be pulled out from the switch SFP slot 2.
