Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, and in particular to an optical module unlocking mechanism and an optical module that prevent unlocking failure and structural component damage. Background Art

[0002] An optical module is a device that can convert optical signals into electrical signals and vice versa. It includes at least: a structural part and a pull ring. The structural part includes: a base and an upper cover covering the base. The two ring arms of the pull ring slide with the two sides of the structural part respectively, and a spring is arranged between each ring arm and the structural part along the sliding direction. The unlocking end of the ring arm has an unlocking protrusion.

[0003] The optical module is inserted into the cage. When unlocking, the pull ring is pulled outward to make it move outward on the structural member, and during the outward movement, the unlocking protrusion on the pull ring is used to push the spring piece on the cage outward by a predetermined size to achieve unlocking. When the size of the unlocking protrusion on the pull ring in the optical module is abnormal, the unlocking protrusion will not be able to push the spring piece on the cage outward by a sufficient size. At this time, the optical module fails to be unlocked and the optical module will continue to be locked in the cage.

[0004] In addition, when the optical module is inserted into the cage and is in a locked state, the cage's spring clip will hold up a small part of the optical module's structure above or below to prevent the module from being positioned abnormally, thereby causing performance abnormalities. When the cage is plugged in and out for a long time, the spring clip will deform, thereby damaging the structure and causing the cage's spring clip limit to fail. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an optical module unlocking mechanism and an optical module which can prevent unlocking failure and structural component damage, so as to overcome the deficiencies in the above-mentioned prior art.

[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: an optical module unlocking mechanism that prevents unlocking failure and structural damage, comprising: a structural member and a pull ring, wherein the two ring arms of the pull ring are respectively slidably matched with the two sides of the structural member in the length direction, the unlocking ends of the ring arms have unlocking protrusions, and an unlocking piece that does not overlap with the unlocking protrusion in a non-unlocked state and is hidden in the side surface of the structural member is arranged on the outer side of the unlocking end of each ring arm, the unlocking piece is provided with an outer spring piece, and the movable end of the outer spring piece is close to the unlocking protrusion; during the process of pulling the pull ring outward to unlock, the outer spring piece gradually overlaps with at least a partial area of ​​the unlocking protrusion, so as to push the movable end of the outer spring piece outward, so that the movable end extends to the outside of the structural member and pushes the spring piece on the cage to complete the unlocking.

[0007] The beneficial effect of the utility model is that during the process of pulling the pull ring outward to unlock, the unlocking protrusion will gradually overlap with the outer spring piece, and the unlocking protrusion will push the movable end of the outer spring piece outward, so that the movable end of the outer spring piece extends to the outside of the structural member and pushes the spring piece on the cage to complete the unlocking. By additionally adding an outer spring piece with a certain thickness between the unlocking protrusion and the spring piece on the cage, even if the size of the unlocking protrusion is abnormal, the outer spring piece can make up for the insufficient size of the spring piece on the cage pushed out by the unlocking protrusion, so as to achieve the unlocking condition and avoid the phenomenon of unlocking failure. In addition, in the non-unlocking state, the outer spring piece is hidden in the side of the structural member and will not extend out of the structural member at will, so that the optical module will not interfere with the insertion of the optical module when it is inserted into the cage, ensuring the smoothness of plugging and unplugging. At the same time, there is no risk of pulling the pull ring too much when unlocking, so as to avoid the optical module being stuck in the cage.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the lower end surface of the outer spring piece is lower than or flush with the lower end surface of the cage upper spring piece, and the upper end surface of the outer spring piece is higher than or flush with the upper end surface of the cage upper spring piece.

[0010] The above further beneficial effect is that the outer spring sheet completely covers the width of the spring sheet on the cage, so that the spring sheet on the cage can be completely popped up, avoiding damage to structural parts, preventing the optical module from failing to position and affecting performance.

[0011] Furthermore, the two side surfaces of the structural member each have a recessed groove extending from the optical end thereof toward the gold finger end, and the two ring arms of the pull ring are respectively located in the two recessed grooves of the structural member and slidingly cooperate with the structural member in the length direction; the unlocking piece is located in the recessed groove, and the upper and lower ends of the unlocking piece are respectively stuck in the recessed groove.

[0012] Furthermore, the upper and lower groove walls of the recessed groove are respectively provided with clamping grooves, and the upper and lower ends of the unlocking piece are respectively located in the two clamping grooves of the recessed groove.

[0013] A further beneficial effect of adopting the above method is: preventing the unlocking piece from falling off or shifting along the pulling direction of the pull ring, thereby ensuring the reliability of unlocking.

[0014] Based on the above technical solution, the utility model also provides an optical module, including an optical module unlocking mechanism that prevents unlocking failure and structural component damage.

[0015] The above method has the further beneficial effect of effectively avoiding unlocking failure and ensuring the reliability of plugging and unplugging the optical module and the cage. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] An unlocking piece 3 is arranged outside the unlocking end of each ring arm 210. In the unlocking state, the unlocking piece 3 does not overlap with the unlocking protrusion 211. The unlocking piece 3 has an outer spring piece 310, and the movable end of the outer spring piece 310 is close to the unlocking protrusion 211. In the unlocking state, the outer spring piece 310 does not extend outside the structural member 1, that is, it is hidden in the side of the structural member 1.

[0030] During the process of pulling the pull ring 2 outward to unlock, the outer spring piece 310 gradually overlaps with at least a partial area of ​​the unlocking protrusion 211. When the unlocking protrusion 211 gradually overlaps with the outer spring piece 310, the unlocking protrusion 211 pushes the movable end of the outer spring piece 310 outward, so that the movable end of the outer spring piece 310 extends to the outside of the structural member 1 and pushes the spring piece 410 on the cage 4 to complete the unlocking. By adding an additional outer spring piece 310 with a certain thickness between the unlocking protrusion 211 and the spring piece 410 on the cage 4, even if the size of the unlocking protrusion 211 is abnormal, the outer spring piece 310 can make up for the insufficient size of the spring piece 410 on the cage 4 pushed out by the unlocking protrusion 211, so as to meet the unlocking condition and avoid the phenomenon of unlocking failure.

[0034] Example 3

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, this embodiment is a further improvement on the basis of Embodiment 1 or 2, and the details are as follows:

[0036] The two side surfaces of the structural member 1 each have a recessed groove 110 extending from its optical end toward the gold finger end. The two ring arms 210 of the pull ring 2 are respectively located in the two recessed grooves 110 of the structural member 1 and slideably cooperate with it in the length direction. The two ring arms 210 are both hidden in the side surface of the structural member 1. The unlocking piece 3 is located in the recessed groove 110, and the upper and lower ends of the unlocking piece 3 are respectively stuck in the recessed groove 110.

[0037] Furthermore: the upper and lower groove walls of the recessed groove 110 are respectively provided with a card groove 120, and the upper and lower ends of the unlocking piece 3 are respectively located in the two card grooves 120 of the recessed groove 110, so as to prevent the unlocking piece 3 from falling off or being displaced along the pulling direction of the pull ring 2, thereby ensuring the reliability of unlocking.
