TECHNICAL FIELD

[0001] The present application relates to the field of optical communication, in particular to an unlocking mechanism and an optical module. BACKGROUND

[0002] With the rapid development of the field of optical communication, the current locking mode of the optical module is generally to extrude the elastic pieces (strips) on both sides of the cage inward, and the unlocking mode is to push the elastic pieces (strips) on both sides of the cage outward. Whether it is locking or unlocking, it is necessary to deform the elastic pieces (strips) by driving. Since the elastic pieces (strips) have elastic characteristics, when plugging and unplugging multiple times, the elasticity of the elastic pieces (strips) will weaken, and the deformation of the elastic pieces (strips) will not be well restored, resulting in poor locking effect of the optical module.

[0016] Further, a wedge-shaped gap is formed in a groove wall of the groove away from the optical port, and the wedge-shaped gap can drive the clamping strip to be separated from the groove when the base is pulled out.

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. In the case of no conflict, the embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the application.

[0028] The unlocking mechanism of the application is described below with reference to Figure 1 、 3 , 5, 6, comprising:

[0029] The pull ring 1 has a stroke of reciprocating rotation in a vertical plane;

[0030] The follower 2 has a stroke of reciprocating movement in a vertical direction;

[0031] The two lock blocks 3 are correspondingly clamped and locked with the two clamping strips 4 of the cage and have a stroke of reciprocating rotation in a horizontal plane;

[0032] The follower 2 can move with the rotation of the pull ring 1, the two lock blocks 3 can synchronously rotate with the movement of the follower 2, and the two lock blocks 3 can be unlocked with the corresponding clamping strips 4 through rotation. In this way, the clamping and locking are achieved through the clamping of the lock blocks 3 and the clamping strips 4, and the unlocking is achieved through the rotation of the lock blocks 3, so that the number of deformations of the clamping strips 4 and the deformation amount of the clamping strips 4 are reduced during locking and unlocking, thereby ensuring the quality stability of the clamping strips 4 and the clamping and locking effect, and the linkage effect is achieved through the pull ring 1 and the follower 2, so that the locking and unlocking can be achieved through the rotation of the pull ring 1, and the operation is convenient;

[0033] In this embodiment, the unlocking mechanism is in a locked state when the pull ring 1 is in a vertical state, and the unlocking mechanism is in an unlocked state when the pull ring 1 is in a horizontal state.

[0034] Reference is made toFigure 3 The pull ring 1 comprises a ring body 101 and at least one protrusion 102 arranged on the ring body 101, the follower 2 is provided with a plurality of sliding grooves 2021 distributed in the horizontal direction and corresponding to the number of the protrusions 102, and the protrusions 102 are in sliding fit with the corresponding sliding grooves 2021. In this way, when the pull ring 1 rotates, the protrusions 102 rotate with the ring body 101, and through the sliding fit of the protrusions 102 and the sliding grooves 2021 and the stroke characteristics of the follower 2 moving in the vertical direction, the follower 2 is driven to move in the vertical direction.

[0035] In this embodiment, the protrusions 102 are arranged on both sides of the ring body 101, so that the ring body 101 can drive the follower 2 to move stably in the vertical direction when rotating, and the sliding grooves 2021 are also arranged on both sides.

[0036] In this embodiment, the protrusions 102 are arranged near the rotation center of the ring body 101.

[0037] In this embodiment, when the pull ring 1 rotates from the vertical state to the horizontal state, the follower 2 moves downward, and vice versa, the follower 2 moves upward.

[0038] Referring to Figure 1 , 2 The follower 2 is further provided with at least one spring 5 arranged in the vertical direction. In this way, the spring 5 can lock and assist the reset of the follower 2, and in this embodiment, when the unlocking mechanism is in the locked state, the spring 5 is in the normal state, and when the unlocking mechanism is in the unlocked state, the spring 5 is in the compressed state.

[0039] Referring to Figure 3 , 4 The two sides of the follower 2 are further provided with guide grooves 2031 distributed in the vertical direction, and the two guide grooves 2031 gradually approach each other from top to bottom, and the two locking blocks 3 are in sliding fit with the two guide grooves 2031 one by one. In this way, when the follower 2 moves in the vertical direction, the locking block 3 rotates through the guide groove 2031;

[0040] In this embodiment, when the follower 2 moves downward, the corresponding locking block 3 expands outward on one side and shrinks inward on the other side in sliding fit with the follower 2, and vice versa, the corresponding locking block 3 shrinks inward on one side and expands outward on the other side in sliding fit with the follower 2; and through cooperation with the clamping strip 4, the follower 2 can move downward, the inwardly shrunk end can be unlocked with the clamping strip 4, and the follower 2 can move upward, and the outwardly expanded end can be locked with the clamping strip 4.

[0041] Referring to Figure 3The ring body 101 is in U shape, and the vertical part 101a of the ring body 101 comprises two spaced-apart supporting parts 1011 and a connecting part 1012 connecting the two supporting parts 1011. In this way, the stability of the ring body 101 is strengthened by the connecting part 1012, and the carrying capacity of the ring body 101 is improved.

[0042] A light module, see Figure 1 , comprising the unlocking mechanism, further comprising a base 6, and the unlocking mechanism is installed at the base 6 close to the light port.

[0043] See Figure 5 , 6 The two sides of the base 6 are respectively provided with grooves 601 for installing two lock blocks 3, and the two lock blocks 3 can be clamped and matched with the corresponding clamping strips 4 in the corresponding grooves 601. In this way, the installation space of the lock block 3 and the clamping locking space are provided by the grooves 601, and enough space is ensured to prevent the clamping strip 4 from deforming in the locked state.

[0044] See Figure 5 , 6 The lock block 3 comprises a block body 301 in L shape in cross section, and the transverse part 301a of the block body 301 is clamped with the corresponding clamping strip 4. In this way, the clamping strip 4 is locked by the transverse part 301a, which is simple in structure and does not deform the clamping strip 4, ensuring the quality of the clamping strip 4;

[0045] And in this embodiment, the lock block 3 further comprises a slide rod 302 connected with the block body 301, and the slide rod 302 is slidingly matched with the follower 2.

[0046] See Figure 5 , 6 The groove 601 is provided with a wedge-shaped notch 6011 on one side groove wall away from the light port, and the wedge-shaped notch 6011 can drive the clamping strip 4 to separate from the groove 601 when the base 6 is pulled out. In this way, after the unlocking mechanism is unlocked, the base 6 and the clamping strip 4 still have the locking effect, and complete unlocking needs to be achieved by moving the base 6, and the wedge-shaped notch 6011 is further ensured to have the minimum deformation of the clamping strip 4 to ensure the quality of the clamping strip 4.

[0047] See Figure 3The base 6 is further provided with two limiting blocks 7 at intervals, the follower 2 comprises a guide block 201 sliding between the two limiting blocks 7, two sliding plates 202 sliding outside the base 6, and two limiting plates 203 vertically arranged at the ends of the two sliding plates 202 respectively, and the two limiting plates 203 can slide along the groove walls of the two grooves 601 respectively. In this way, the follower 2 is ensured to slide in the vertical direction by the limiting blocks 7, and the stability of the follower 3 moving in the vertical direction is ensured by wrapping and sliding the part of the base 6 by the limiting plates 203 and the sliding plates 202.

[0048] In this embodiment, the spring 5 is arranged between the guide block 201 and the base 6.

[0049] In this embodiment, the sliding groove 2021 is arranged on the sliding plate 202, and the guide groove 2031 is arranged on the limiting plate 203.
