Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to a pull ring mechanism and an optical module. Background Art

[0002] In some special occasions, multiple optical modules are stacked up and used. In this case, the pull ring on the lower optical module will be blocked by the AOC or DAC cable of the upper optical module. This is especially true for OSFP optical modules, whose pull ring is relatively short, making it impossible to pull the pull ring on the lower optical module. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a pull ring mechanism and an optical module to overcome the deficiencies in the above-mentioned prior art.

[0004] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a pull ring mechanism, comprising: a handle and an auxiliary handle, the handle being fixed to a sheet metal part, the auxiliary handle slidingly cooperating with the handle through a slide rail structure, the auxiliary handle being able to slide along the length direction of the handle, and the length of its tail end extending outside the tail end of the handle becoming longer or shorter during the sliding process within the stroke range limited by the slide rail structure.

[0005] The beneficial effect of the present invention is that the pull ring mechanism is applied to the optical module. When multiple optical modules are stacked up and down, the optical modules are plugged into the cage in sequence. When the optical modules are subsequently unlocked, the auxiliary handle is slid along the length direction of the handle so that the length of the tail end thereof extending outside the tail end of the handle becomes longer. Since the pull ring mechanism can extend the handle length compared to the pull ring in the prior art, it can avoid being blocked by the AOC or DAC cable, making it easier for the staff to apply force to unlock the optical module.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the handle includes: two side arms and a connecting part, the two ends of the connecting part are respectively connected to the tail ends of the two side arms, the front ends of the two side arms are fixed to the sheet metal, and the auxiliary handle slides with the two side arms through a slide rail structure.

[0008] Furthermore, the slide rail structure includes: two tracks, the two tracks are respectively fixed on the two side arms, the two tracks are distributed in parallel on one side of the connection part close to the sheet metal, the tracks on each side arm are respectively distributed along the length direction, and a slider is provided on each of the two tracks for sliding, and the slider is fixed to the auxiliary handle, and the slider does not leave the track during the sliding process on the track.

[0009] A further beneficial effect of the above is that a stable and reliable sliding fit can be ensured between the auxiliary handle and the handle.

[0010] Furthermore, the two rails are respectively fixed on the inner side surfaces of the two side arms, the upper surfaces of the connecting portion and the two rails are lower than the upper surfaces of the side arms, and the auxiliary handle is located between the two side arms.

[0011] A further beneficial effect of the above method is that the track can be hidden on the handle.

[0012] Furthermore, the upper surfaces of the auxiliary handle and the slider are lower than the upper surface of the side arm.

[0013] A further beneficial effect of the above method is that the auxiliary handle and the slider can be hidden on the handle.

[0014] Furthermore, the auxiliary handle is a U-shaped structure, and the U-shaped end of the auxiliary handle is located at one end close to the sheet metal. The slider is a C-shaped structure, and the two sliders are respectively fixed to the area of the auxiliary handle close to its U-shaped end. The ends of the two arms at the open end of the auxiliary handle are each provided with a limiting portion, and the two limiting portions are located on the side of the connecting portion away from the sheet metal. The lower surface of the limiting portion is lower than the upper surface of the connecting portion, and the distance between the two limiting portions is greater than the wire diameter of the AOC or DAC cable plugged into the optical module.

[0015] The above-mentioned further beneficial effects are: by arranging the two rails to be distributed in parallel on the side of the connecting part close to the sheet metal, and arranging the two limiting parts to be located on the side of the connecting part away from the sheet metal, the lower surface of the limiting part is lower than the upper surface of the connecting part, and the slider is designed as a C-shaped structure, which can effectively prevent the auxiliary handle from detaching from the handle during the sliding process, and the distance between the two limiting parts is greater than the wire diameter of the AOC or DAC cable plugged into the optical module. When the auxiliary handle extends longer from the tail end of the handle, the AOC or DAC cable can enter the auxiliary handle from the gap between the two limiting parts, thereby avoiding the obstruction of the AOC or DAC cable.

[0016] Furthermore, the length of the auxiliary handle is smaller than the length of the side arm, and a receiving opening for receiving the limiting portion is provided at each of the two corresponding limiting portions on the side of the connecting portion facing away from the sheet metal component.

[0017] A further beneficial effect of the above method is that the auxiliary handle can be completely hidden on the handle.

[0018] Furthermore, the two rails are connected to the connecting portion, the upper surface of the rails is flush with the upper surface of the connecting portion, and the lower surface of the rails is flush with the lower surface of the connecting portion. The connecting portion, the two rails and the two side arms are integrally formed.

[0019] The above method has the further beneficial effects of facilitating production and simplifying the processing flow.

[0020] Furthermore, the slider and the auxiliary handle are integrally formed.

[0021] The above method has the further beneficial effects of facilitating production and simplifying the processing flow.

[0022] Based on the above technical solution, the present invention further provides an optical module, comprising a pull ring mechanism connected to a structural member.

[0023] A further beneficial effect of the above-mentioned method is that when multiple optical modules are stacked up and down, the optical modules are plugged into the cage in sequence. When unlocking the optical modules subsequently, the auxiliary handle is slid along the length direction of the handle so that the length of the tail end thereof extending outside the tail end of the handle becomes longer. Since the pull ring mechanism can extend the handle length compared to the pull ring in the prior art, it can avoid the obstruction of the AOC or DAC cable, making it easier for the staff to apply force to unlock the optical module.
